An OER COUP: College Teacher and Student Perceptions of Open Educational Resources

Despite increased development and dissemination, there has been very little empirical research on Open Educational Resources (OER). Teachers and students involved in a large-scale OER initiative at eight community colleges across the United States were given a detailed questionnaire aimed at uncovering their perceptions of the cost, outcomes, uses and perceptions of quality of the OER used in their courses. Teachers and students alike reported significant cost savings and various pedagogical and learning impacts due to the implementation of OER in the classroom. In addition, most students and teachers perceived their OER to be at least equal in quality to traditional textbooks they had used in the past. Implications for further research are discussed.

While OER provide new opportunities for access to educational resources, many also see in OER an opportunity for students and school districts to save substantial amounts of money by eliminating the need to purchase expensive textbooks (Bliss, et al, 2013;Hilton & Wiley, 2011). For example, Caswell (2012) describes a major curriculum redesign initiative undertaken by the Washington State Board of Community and Technical Colleges to leverage OER and original, faculty-authored content. The intended result is that professors will be able to use OER to replace traditional textbooks, dramatically lowering the cost that students pay for their education.
While much work has been done to create, disseminate, and champion OER, relatively little theory-based, generalizable research has been done to examine its use and impacts (Bateman, Lane & Moon 2012). Vital questions about many aspects of OER still need to be addressed, which we view through the lens of a "COUP framework" (Cost, Outcome, Use, Perceptions) encompassing the impacts on Cost, impact on Outcomes, Use patterns, and Perceptions of quality of OER. The four components of the COUP framework comprise the salient aspects of education that we consider most likely to be impacted by the use of OER. Specifically, OER could potentially affect educational costs because the expense of copying and distributing openly licensed materials (especially digital materials) can be greatly reduced compared to most copyrighted educational materials. Reduced educational costs, together with increased ability to keep OER up-to-date and access to materials on the first day of class, have the potential to impact student outcomes. Outcomes could also be affected by how teachers and students use OER in ways that differ from how they use traditional materials. Finally, student and teacher perceptions of OER have the potential to shed light on conflicting use patterns and outcomes. For these and other reasons, the use of a framework such as COUP provides a minimal basis for future comparative research on OER.
Preliminary research has begun to explore the extent to which replacing traditional textbooks with OER can both decrease costs and improve outcomes in middle and high schools. Wiley et al (2012) examined the impact of using open textbooks based on materials produced by the CK-12 Foundation for three high school science courses. They found that open textbooks were over 50% less expensive than the traditional textbooks recommended for adoption, and that there was no negative impact on student learning outcomes as measured by state standardized tests.
Despite promising early results in the K-12 space, no empirical work around the costs, outcomes, uses, and perceptions of open textbooks appears to have been done in community college settings. In a potential case of policy outpacing evidence, the US Department of Labor recently required open licensing of all educational materials produced under the Trade Adjustment Assistance Community College and Career Training (TAACCCT) Grant Program -a two billion dollar investment in OER. Given this new policy, it behooves us to understand how OER impact community college students and teachers from a COUP perspective. The current study contributes to the knowledgebase by providing additional detail about these four impacts of OER in the community college setting.

Methodology
The study was conducted in the context of an open education initiative called Project Kaleidoscope (http://www.project-kaleidoscope.org/). This initiative is comprised of eight community colleges serving predominantly at-risk students. These colleges work together to create courses that replace traditional, expensive textbooks with OER. During the 2011-2012 academic year, Project Kaleidoscope (PK) impacted over 4,000 students across 80 teachers in a controlled pilot, with another 5,000 students using PK course designs and materials outside the controlled pilot.
Over 80 community college teachers who used PK texts in their Winter 2012 courses were asked to complete an online questionnaire about their impressions of these resources in terms of cost, outcomes, use and perceptions of quality (Annex A). Requests were made via email from the study authors containing a link to the questionnaire in early March, near the end of the first half of the semester for most courses. Some institutions had courses on the block schedule and instructors of these courses were sent email requests in mid-April.
Additionally, all instructors were provided with a link to a student version of the questionnaire (Annex B) and asked to forward that link onto their students. Follow-up emails were sent to non-responding teachers and teachers with low numbers of responding students every 10-15 days through to the end of the semester.
The questionnaires included multiple-choice, multiple-select, and constructed response items that asked instructors and students about each of the components of the COUP framework. For instance, teachers and students were asked to compare the cost, quality and patterns of use of their open textbook to what they normally experienced with traditional textbooks. In addition, teachers were asked about the impact of the open textbook adoption on their own preparation time and pedagogy and on their students' preparedness and engagement.

Results
Fifty-eight teachers from all eight PK institutions completed some items on the questionnaire. Respondents used PK texts to teach a variety of subjects, ranging from business fundamentals to introductory psychology. Nearly 60 percent of teacher-respondents were female, over 60 percent had taught at the college level for more than 6 years, and over 70 percent typically taught three or more courses each term. Only three teachers did not have a master's or doctoral degree. Sixty-seven percent of teachers indicated that they had taught the course in which PK materials were used at least three times, and all but six teachers had taught the course at least once. Finally, 42 percent of responding teachers taught at one of the eight PK institutions, with the remaining 58 percent were spread fairly evenly across the remaining seven schools. This response distribution was fairly parallel to the actual distribution of teachers across the PK schools.
In all, 490 students from all eight PK institutions completed the questionnaire. The disciplines within which students who responded to the questionnaire took courses are shown in Figure 1. Over 60 percent of student-respondents were female, and, on average, had completed 2.5 academic terms or semesters. Sixty-one percent of students in PK courses who responded to the questionnaire indicated having received a Pell grant or fee waiver, a proxy for low socioeconomic status. The overall percentage of Pell eligible students in the surveyed population is not known, but it is likely more than 50 percent. Thirty-four percent of students indicated having received loans to fund their education. Nearly 50 percent of student-respondents reported a college GPA of 3.0 or higher on a 4.0 scale. The majority of respondents came from three of the eight PK institutions (40 percent from one, 20 percent each from two others). The remaining 20 percent of respondents were spread across the other five PK schools in decreasing proportions. Response proportions were similar to actual enrollment in PK courses, with the most represented institution in our study having the highest proportion of students in the PK initiative and the least represented institution having the lowest proportion of students in PK courses. Figure 1: Distribution of student responses by discipline *Indicates a variety of different courses within a similar discipline (e.g. "math" includes developmental math, elementary developmental algebra, intermediate developmental algebra, and college algebra courses).
In the remainder of this section, we present the results of our study in terms of the COUP framework: cost, outcomes, use and perceptions of open digital textbooks in community college courses.

Cost
Teacher and student reports of traditional textbook costs were fairly well aligned. Teachers reported typically requiring students to spend at least $80 per course on required textbooks, while students reported spending between $60 and $83 per course on such texts (Figures 2 and 3). Figure 2: Distribution of teacher responses to the question "When you have taught this course in the past, how much have students generally been asked to spend on textbooks?" (n=49). Likewise, teacher and student reports of spending on OER texts were very similar. Most teachers reported requiring students to spend less than $20 on texts in their PK courses and students reported spending between $12 and $17 on average (Figures 4 and 5). However, a focus on the mean is misleading as most students reported spending no money at all on their OER texts. Indeed, the mode and median student reported spending on PK textbooks were both $0. Figure 4: Distribution of teacher responses to the question "How much have students been asked to spend on required textbooks in this course this semester?" (n=50). Figure 5: Distribution of student-reported spending on PK texts during the 2012 Spring Term. Seventy-two percent (n=488) reported spending no money, and another six percent reported spending less than $20.
Students who reported spending no money on textbooks in their PK courses were subsequently asked to select among various reasons for why they did not spend any money ( Figure 6). Eighty-eight percent of these students selected "The texts were online and free." Interestingly, seven percent of students surveyed indicated they "couldn't afford to purchase texts." However, all but two of these students also selected "The texts were online and free," possibly indicating some confusion about what "affording a textbook" means. Figure 6: Reasons students selected for why they didn't spend any money on texts in PK courses. Students were allowed to select more than one option (n=348).

Outcomes
We explored how open textbook adoption impacted students and teachers in several meaningful ways. Teachers were asked questions relating to three aspects of the impact of PK texts: teacher preparation time, pedagogical change, and student preparation. Finally, a few students shared thoughts about the impact of their OER textbook on their learning, though no specific question on this point was included in the questionnaire.

Preparation time
More than half of teachers reported spending more time preparing for their PK course compared to when they had taught the course in the past. Since some teachers participated in the actual development of the PK texts, all teachers were asked to report preparation time excluding time spent on text development ( Figure 7). A chi-square test was used to determine whether there was a statistical difference in time spent depending on teacher participation in text development, but no significant difference was found [χ 2 (2) = 1.64, p = .441].

Pedagogical change
We also looked at how the flexibility and adaptability inherent in OER affected teachers' pedagogical practice. Seventy-five percent of teachers reported some change in instructional practice when they used the PK texts. Some reported changes were a direct result of the digital nature of many of the texts and other changes were an indirect effect resulting from the impact of PK texts on students. In the first case, many teachers reported increasing their effective use of technology in the classroom, while a handful reported technology getting in the way of teaching and learning. In the second case, teachers reported that their students were more engaged and interested in the material in the PK courses. These teachers, in turn, felt more latitude to give more assignments and assessments, as well as cover more content.
Over 20 percent of teachers described the advantages of OER in terms of student access to materials at the very beginning of the course. For example, one teacher wrote, "Having the book immediately available online helps the class progress faster." And another teacher described how his students "are prepared from the beginning of class." A few teachers discussed other advantages of continuous online access to materials, including more student interest and engagement. One teacher described this advantage, saying, "Students are better prepared as they have access to the reading materials at little or no cost. Students are more engaged and have more interesting questions." Another teacher explained how better access to resources affected her class instruction: "I am able to refer to material knowing that all students will have access to the same material." Nearly a quarter of teachers reported no change in their teaching practice as a result of using the OER textbook. For example, one teacher said that her practice changed "remarkably little…the text provides much of the same content as a commercial text." Another teacher noticed a change in practice, but did not attribute this to the OER text: "No change due to the textbook. Lots of change due to my growth as a teacher." Another quarter of teachers mentioned changes in time spent using technology, for better and worse. Several teachers mentioned technology as a barrier to instruction and learning: "I spend a lot more time helping students access and navigate the website. I refer to posts I make to the website during class on a frequent basis, mainly because I am not convinced they are using the links I give them." Even more time consuming, one teacher reported having to "modify several assignments in order to help students without access to [the] Internet or [who] have problems accessing materials through the net." On the other hand, some teachers felt that technology helped their students become more interested and engaged in the course material. One teacher described how he was "able to use technology more; for example, I can access the online materials and engage all of my students during class time" while another teacher "love [ed] showing the video clips during the PowerPoint presentation." Teachers reported a wide variety of other positive changes to their practice. These changes were reflected in 30 percent of responses and ranged from giving more assignments, to more activity in class, to creation of more assessments and learning tools. One teacher even took the opportunity to have his students write an open textbook: "I've really backed off lecturing. Because of the lack of high-quality OER materials for biology, my students are spending lots of time writing their own book." Another teacher noted how much more aligned her instruction was with the course materials: "My weekly posts/lecture notes are directly related to the OER textbook. It has helped my instruction as far as the students using a functional resource for their papers." The positive pedagogical effect of OER is reflected in the comment of one late-adopting teacher: "I didn't integrate until the end of the semester. Had I known how happy and responsive my students would be to the use [of] the OER textbook, I would have started much earlier in the semester."

Student preparedness
Sixty-three percent of teachers believed that their students were equally prepared in the course with PK texts compared to students in the same course before implementation of PK texts ( Figure 8). Another 26 percent felt that their students were more prepared than students in the same course in the past. The final 11 percent perceived their students as being less prepared. Figure 8: Distribution of teacher responses to the question, "How did your students' preparedness in the course compare to previous semesters?" (n = 54).

Student comments on learning
Many students commented that they were better able to learn with an online book. One student wrote that he found himself "using [it] a lot and learning better than before." Another student noted that the OER text "helped me to study and learn what I needed to learn within the course." Of particular note, a learning-disabled student wrote, "I have a learning disability and it seemed like I am doing better in my grades reading the texts online than in my [printed] books." At the same time, a few students felt that the OER texts impeded their learning. For example, one student wrote that his textbook was "not the best quality to learn from." Another student gave a bit more detailed explanation: I think the textbook is terrible. First of all, the entire book is black and white. The examples are good, but not having color is making the book 10X harder to read and understand. They have quizzes and true/false questions at the end of the chapter but they don't provide answers for them....how am I suppose to learn?! More examples of both positive and negative student-reported impacts on learning are included in a later section on students' perceptions of quality.

Use
Neither teachers nor students reported meaningful increases in student use of PK texts compared to use of traditional texts. Students were asked to report how frequently they used their textbooks, both typically and in the PK course specifically. For typical courses, nearly half of the students reported using textbooks two to three times per week and another quarter reported using them daily (Figure 9). For PK courses, slightly less than half of the students reported using the OER textbooks two to three times per week, but slightly more than a quarter reported using them daily (Figure 10). The largest difference between reported typical textbook usage and PK textbook usage was in the "Never" category. Only one percent of students reported never using textbooks typically, but 12 percent reported never using the PK texts. Nearly 75 percent of students who reported that they never used the OER textbook were associated with just 5 different teachers. Figure 9: Student responses to a question about how often they used the required texts in typical courses (n=484). Figure 10: Student response to a question about how often they used the textbook in their PK courses (n=486).

Perceptions of Quality
Eleven percent of teachers and six percent of students perceived the OER textbooks as being of worse quality than traditional textbooks they had used in the past. In all cases, these users cited technology problems or general poor text quality as reasons for giving a low rating.
Six teachers provided a description of what they thought made the OER texts worse than texts in other courses. Their responses clustered in two major categories: technology issues and poor quality. The two teachers who mentioned technology issues did not provide much detail, but it appears that student access to the Internet and perceived student preference for printed textbooks was at the heart of what made the OER texts worse for these teachers. For example, one of the teachers wrote, "Students have limited access-want print sources [because] that is what they are used to." The other teacher simply wrote, "That it's online." The remaining four teachers who thought the OER texts were worse than other texts focused on various aspects of quality in general. One teacher explained that in her text the "information is disconnected [and] the images and diagrams are poor," another teacher mentioned that, "the layout is hard to read," and a third teacher described the coverage of her textbook as "not as thorough" as her previous book. The fourth teacher described his perceptions of the limitations of OER in his discipline and a creative solution he devised to overcome these challenges: "The Online Biology book is terrible. It is too detailed, poorly written, and the diagrams are not nice. This is why I'm writing an ecology text with students.
[The online text] sources are either very outdated, more advanced than the level I teach at, and poor quality." In all, 20 students provided a description of what they thought made the OER texts worse than other texts they had used in the past. Their responses clustered in the same two major categories: technology issues and text quality.
Student comments on technology issues centred on website functionality and accessibility of materials in multiple formats. For example, one student expressed a desire for the website to "have an app for phones if the content is going to go through the Internet. If the content was able to be put into an e-reader such as the Kindle, that would be amazing as well." Another student wrote about how "the left and right scroll bar made the texts a nuisance to read." A third complained that "the website format made the text difficult to view." Most students who thought the OER texts were worse than traditional texts were concerned about general text quality. These student comments related to the quality of the content itself, alignment of the content with course expectations, presentation issues (like typos and grammar), and the physical quality of the print-on-demand OER texts. One student noted the he "didn't like the format. It asks a question and then answers it in the following paragraphs.
To me it is not clear info and I have to often re-read." Another student wrote about her text's alignment with the course: "The info on this site for my course goes beyond the scope of my class and fails to break down the basics. Usually if I don't understand something in lecture I can go to my textbook for clarification. However this site failed to break down the basics for me before delving too deeply into the details." Despite these important critical comments, the majority of teachers and students perceived the OER textbooks as being of at least equal quality compared to the traditional textbooks they had used in the past. Respondents in this category were not asked to explain their reasoning.
Finally, a large proportion of teachers (34 percent) and students (39 percent) perceived the OER textbooks as being of better quality than traditional texts. In total, 17 teachers provided a description of what they thought made the OER texts better. Their responses clustered in three major categories: cost, customization, and general quality.
More than 20 percent of the positive teacher comments reflected a feeling that the cost of the OER textbook was better both for the students and for themselves. For example, one teacher said, "The materials were free to my students, which reduced a barrier to their chances for academic success." Another teacher stated, "It's very helpful because I didn't have to spend lots of money on the text book." A full one-third of teacher comments focused on the customization aspect of the OER textbook. They expressed appreciation at being able to tailor the book to their course and to their students. One teacher stated, "I put together the resources, so I could write the information my students receive. Further, I can select the best (easiest to understand and clearest written) sources for my students." Another teacher said the OER were "perfectly aligned with our critical reading course learning objectives. Finding critical reading instructional materials for college-level students is very difficult, and now we have custom-made materials that all instructors can use." Forty-five percent of the positive teacher comments centred on the better quality of the OER textbook. These comments on quality addressed the simplicity, relevancy, and organization of the textbook. One teacher appreciated the "currency and articulation of content [and the] organization of content," while another teacher liked that there were "no bells and whistles. [The book] covers all the required materials [and] presents the material in a simple, easy to understand fashion." Other teachers stated that the book was well-written and more interesting than books they had used in the past. For example, one teacher responded that the book they used "is well written and has a good mixture of text, questions and case studies. The business communication textbook I used for a previous class was very dry." In addition, 160 students provided a description of what they thought made the OER texts better. Their responses clustered in six major categories: technical advantages, learning aides, customization/alignment, cost, access, and general quality/presentation.
Most of the comments on technical advantages of PK texts focused on using a built-in search functionality to look for specific text. One student explained this advantage, saying the PK text was better "because it gives you the option to look for specific chapters…and find any keyword to start studying and reviewing." Another student mentioned that "it was easier to browse through and find the information that was needed." Other technical advantages included being able to "zoom in the size of the print" for "reading comfort" and "scroll up and down to any part of the book quickly." Nine percent of student responses focused on learning aids. In these comments, students talked about the usefulness of embedded videos, quizzes, visuals, and other study helps. One student felt that his OER text was better than traditional texts because it "gives video lessons which really help if you don't understand." Another student agreed that "the videos are...very helpful." Ten percent of students recognized the advantages of the customizable nature of the open texts. These students wrote about how their texts were better aligned with content covered in lecture and how the content was "more up-to-date" and "relevant" than other texts they had used in the past. A few students even recognized the pedagogical advantages from the teachers' point of view, as evidenced in the following student comment: "[My text] allowed the instructor to teach as the department intended, instead of using an outside book and basing the class around the book." Because the OER texts were offered to PK students for free, it could be expected that most students would cite cost as a major reason for feeling that their open texts were better than traditional texts. However, only 20 percent of students mentioned cost in their comments. For many of the students who did comment, the cost of their open texts seemed critical to their education. For example, one student said, "I have no expendable income. Without this free text I would not be able to take this course." Most of the students who mentioned cost also gave other, non cost-related, reasons for preferring the open texts over other texts they had used in the past.
Over a quarter of student comments about what made their open texts better than traditional texts centered on convenient access. One student wrote that "it's easier when [my book] is online. I don't have to carry a big book. I could just carry my laptop and I have all the materials I need." Another student explained that "since [the book] is online I can access it anywhere there is an Internet connection." Interestingly, many students explicitly stated that having their texts online was better because "you don't have to carry around a heavy textbook" or worry about it getting damaged.
There was also a wide variety of student comments about the overall quality of the content and presentation of the OER texts. Comments grouped under this theme related to the text being "easy to read," "interesting," and "providing examples." Student comments in this theme also mentioned the organization, layout, navigability, simplicity, concision, and clarity of the open texts compared to more traditional texts. For example, one student said the textbook is, "short and straight to the point with follow-up questions to better one's understanding." Another student described his text as "organized very well and easy to read." In fact, the idea of the open texts being "easy" or "easier" than other texts was the predominate theme throughout all responses to the question asking students to describe what made quality of the OER texts better than those in other courses.
Near the end of the survey, students were given an item that attempted to assess their textbook preferences. This item asked, "How likely are you to register for a future course that uses a textbook like the one used in this course?" The majority of students reported that they would be "Very Likely" (53 percent) or "Somewhat Likely" (32 percent) to register for a future course with a textbook like the one used in their PK courses. Only a few reported being "Somewhat Unlikely" (eight percent) or "Very Unlikely" (seven percent) to register for such a course.
It is important also to consider students' exposure to digital textbooks when interpreting this data. In all, 383 students indicated that their PK texts were accessed primarily in digital format (usually online). Only 93 students indicated that their PK texts were not accessed primarily in digital format. A chi-square test of independence was used to examine whether student likelihood to register for future OER courses depended on digital text exposure. No significant result was found (). The majority of student respondents (76 percent) would be somewhat or very likely to enroll in a future course that uses a text similar to that used in their PK course, regardless of whether their PK text in the 2012 Spring term was primarily online or not.

Discussion
Following the COUP framework, we next discuss the results of this study in terms of cost, outcomes, use, and perceptions of open digital textbooks.
One of the primary goals of Project Kaleidoscope was to dramatically decrease the cost students pay for textbooks. Both teachers and students in the study perceived that textbook costs were reduced by nearly 80 percent. Consequently, the project appears to have been successful in demonstrating that open educational resources can be used to lower the cost of attending community college. Future research should focus on understanding how savings only dropped by 80 percent when the cost of required textbooks on class syllabi was $0.
On the other hand, while there was general agreement that OER reduced the cost of educational materials to students, many teachers reported that using OER required more preparation time than using traditional materials. It is presumed that teachers spent more time preparing to teach either because they were adapting and revising existing OER or they were calculating in the time spent developing the materials specific to this initiative. Either way, this finding has at least one important implication for future OER initiatives: despite the many clear advantages of OER, obtaining instructor buy-in could be hindered by the reality of increased preparation time. One approach to ameliorate this concern would be to get buy-in first from those willing to spend more time preparing and then scale to instructors less willing to spend more time by providing them with pre-existing material. This particular approach was successfully used in the Project Kaleidoscope initiative, where several faculty members were brought on initially to develop content and then others were added later as "adopters." Only some of the adopters reported increased preparation time, indicating that the use of OER does not necessarily lead to more time spent preparing to teach.
While the cost story is quite clear, the teaching and learning outcomes of the project are mixed. Even after removing time spent in the upfront development of the OER textbook replacements, teachers still reported spending more time preparing for classes using these materials. This must be interpreted as a negative outcome of the study. However, the majority of teachers also reported that students using open textbooks were better prepared for class. This should be interpreted as a positive outcome of the study. Future research should determine if faculty think this tradeoff is acceptable. Do teachers spend significantly more preparation time in exchange for students who are only minimally better prepared? Do teachers spend minimally more preparation time in exchange for students who are significantly more prepared?
Student use of their open textbooks appears to be unchanged from their use of other textbooks. This might be interpreted as a "do no harm" or neutral finding. Future research should probe a variety of issues relating to how students could be better prepared for class if their use of textbooks was unchanged. Also, how is it possible that students report that they appreciate the ability to keyword search their books, for example, and still report that their use of the books had not changed?
While some teachers and students perceived the open textbooks as being lower quality than the traditional books they had used before, over three times as many teachers and six times as many students thought the books were higher quality than traditional books. This should be interpreted as a positive finding of the study, particularly in the context of recent concerns about the potential for production and dissemination of low quality OER (e.g., WCET, in press).
Overall, the results of this study on the impacts of replacing traditional textbooks with OER in community college settings are mixed. However, these mixed findings reflect a single approach to using open educational resources in community college classes. Different approaches will likely produce results that are more uniformly negative or positive. We believe that the results presented above should be interpreted as a first effort at using OER at scale -an effort that can be improved upon and strengthened.

Limitations
There are a number of limitations to this study, including the study's reliance on questionnaire data. The results are only as accurate as the perceptions of those being surveyed. For example, we gained data about students' and teachers' perceptions of costs. However, an important follow-up to this study (on cost) would include an inspection of syllabi from the OER and non-OER versions of these courses to determine actual costs of required texts in both versions.
A second general weakness of this study is that student and teacher perceptions about the use and quality of OER were likely coloured by their more general perceptions about the use of technology in education. Results about pedagogical impacts of OER are encouraging for proponents of such resources, but further, in-depth qualitative studies of these kinds of impacts are much needed.
While discussing limitations, we must note that response rate is not a limitation in our study because we were not intending to conduct a survey, in the statistical sense, of a particular population. Our goal was to obtain a large amount of qualitative data rather than a statistically representative sample of the entire population of PK students. Our priority, then, was to obtain data from each of the eight participating institutions and from as many different instructors and students as possible. Indeed, student and faculty responses are quite representative of the spread of participants in PK courses across the institutions. For instance, most responses came from the institution with the largest number of participating instructors and students.
Finally, while our study did not explore the issue, the impact of open textbook adoption on student achievement is an extremely important outcome for future studies. Future research should look at the differences in student success rates across teachers and across time.  (4) Q18 Did you work on the development of the OER textbook for this course?
