Book Description
According to the U.S. Government Accountability Office (GAO), college textbook prices have increased by 186% from 1986 to 2004.1 The impact of rising cost of textbooks is increasingly apparent as students are becoming more selective in the courses they enroll in, as well as more concerned with the quality of the learning experience they receive once enrolled in a course.1 In response to high textbook prices, open-education resources (OER) are increasingly becoming more accepted for student use as an alternative to traditional textbook options. OERs are open-source textbook and/or materials that are free to use without worrying about copyright laws.2 The authors on this study have created an OER textbook3 for engineering majors enrolled in an introductory general chemistry course. Understanding the impact this open-education resource on student success will allow us to explore and provide more cost-effective resources for our students. Specifically, we are interested in exploring how the use of these open-source materials may impact student learning, perceptions, and success when compared to traditional publisher-provided textbooks. We also intend to characterize additional resources used by students beyond their textbook to aid their studies. Understanding which resources students are using the most and why they find them to be useful will allow us to adapt and recommend better and more affordable resources to students. One of our studies compared students using a traditional textbook and students using our OER textbook. For the treatment group, there were significant correlations including an inverse relationship between using the internet as a resource and final grades. We also found statistically significant differences between the control and treatment groups concerning students' perceived helpfulness and use of textbook resources. In our second study we found that of the “official” resources, students use lecturer provided materials via Folio and materials generated during lecture the most and found them to be the most helpful. Of the “unofficial” resources, we found that free online study resources and peer messaging were used the most often and found to be more helpful than paid online study resources and paid or private tutoring.

Book Description
The College of Natural Science and Mathematics, NSM, at California State University Sacramento has a low retention rate, high failure rate and a large achievement gap for freshmen students. Freshmen students who are part of the underrepresented minority -- Black, Latino/a, American Indian and Pacific Islander students -- have even higher failure rates and lower retention rates than the rest of the student population. Of the nine subjects offered by NSM, the courses in the subject of chemistry consistently have the highest failure rates and lowest retention rates. Despite several calls for an increase in science workers, there have been reports of shortages of college graduates with advanced STEM degrees. It is clear that changes need to be made to help boost the retention rate in order to help meet the demand for science workers. This study uses action research to investigate the effect of using humanistic approaches to science, inclusive pedagogy, and affective learning objectives in order keep students engaged and to increase students' sense of belonging in a science course. Previous studies have shown that student engagement and a sense of belonging are both positively correlated with academic achievement. By developing techniques and interventions to help students stay engaged with course material, this study demonstrates that small interventions can have a positive effect on student perseverance and sense of belonging. For this study, five new interventions were introduced in the introductory chemistry course CHEM 4: Chemical Calculations. The interventions focused on adding human elements and social relevance to science education. As a result of these interventions, CHEM 4 students indicated that they felt a greater sense of belonging at the end of the semester than they did at the beginning of the semester. Based on student responses on surveys, students also appeared to maintain their level of interest and engagement throughout the semester. While this study shows that the interventions had a positive effect on students during the two semesters that interventions were implemented, the failure rates and achievement gaps for CHEM 4 remained high. Since this study attempted to address student attitudes to impact student performance, it will be important to monitor both immediate and long-term outcomes.

Book Description
This book takes a fresh look at programs for advanced studies for high school students in the United States, with a particular focus on the Advanced Placement and the International Baccalaureate programs, and asks how advanced studies can be significantly improved in general. It also examines two of the core issues surrounding these programs: they can have a profound impact on other components of the education system and participation in the programs has become key to admission at selective institutions of higher education. By looking at what could enhance the quality of high school advanced study programs as well as what precedes and comes after these programs, this report provides teachers, parents, curriculum developers, administrators, college science and mathematics faculty, and the educational research community with a detailed assessment that can be used to guide change within advanced study programs.

Book Description
Abstract: This study examines how incoming students as well as educators of an introductory college chemistry course evaluate and describe the level of student preparation. Data collection was based on individual and focus group interviews of 11 undergraduate students as well as two university chemistry educators from California State University Long Beach. Chemistry educators generally described the incoming students as unprepared in terms of student skills, conceptual understanding, depth versus breadth, and basic chemical and scientific principles. Incoming chemistry students generally described themselves as unprepared for introductory chemistry in terms of academic rigor and laboratory experiences. The findings of this study have implications for primary and secondary science educators in terms of teaching science content and providing laboratory experiences. Further discussion includes aspects of Common Core State Standards and Next Generation Science Standards.

Book Description
This dissertation explores how student beliefs about the nature of science learning, beliefs in their academic ability, perceptions of the classroom environment, perceptions of external support, and use of resources contribute to success in introductory chemistry as measured by midterm and final exam scores. These factors were selected for study because they are susceptible to instructional intervention. A beliefs and perceptions survey and use of resources framework were developed, tested, and utilized to find predictors for student grades. To measure beliefs and perceptions the Chemistry Beliefs and Perceptions Survey was developed and tested. A total of 428 introductory chemistry students responded to the survey measuring their beliefs and perceptions during Fall 2009. Factor analysis of student responses yielded four categories of beliefs and perceptions: nature of science learning, academic ability, classroom environment, and external support. A hierarchical linear model estimated the influence of student beliefs and perceptions on exam scores. There was a positive relationship between exam scores and (a) belief in academic ability and (b) belief that learning science involves understanding dynamic processes. There was a negative relationship between exam scores and perception of external support. Perceptions of the classroom environment were not strongly related to exam scores. These results were replicated with survey responses collected from students taking the course the following Fall (N=597). To characterize student use of resources, a subset of survey participants (N=61) were interviewed at three time-points spanning the Fall 2009 semester. Interview responses were used to create a Use of Resources Framework. This framework described students as memorizers, procedural thinkers, critical thinkers, or researchers. Students characterized as memorizers or procedural thinkers view outside sources of information as the "authority," while critical thinkers and researchers evaluate information for themselves and generate explanations in their own words by using multiple relevant ideas. The four use of resource levels were shown to predict exam performance. There was a positive relationship between use of resources and exam performance. Survey and interview measures were combined for the subset of 61 students to explore the joint contribution of use of resources along with beliefs and perceptions on exam performance. The influence of student beliefs in their academic ability on exam performance was found to be mediated by use of resources. That is, there was a positive relationship between belief in academic ability and use of resources. There was also a positive relationship between overall use of resources and exam performance. To illustrate these relationships, three case studies are described. The case studies demonstrate the strong relationship between use of resources (for example the textbook, solving problems, interactions with peers) and understanding of chemistry as revealed on the exams. The cases illustrate how students use resources to understand the course material. Memorizers and procedural thinkers explain the idea of boiling based on connection of recalled information with little evaluation of these ideas. Critical thinkers and researchers explain their understanding in their own words, including evaluation of multiple explanations on the topic. These results suggest that it might be valuable to instruct students in productive ways to use resources so they can succeed in chemistry. This may be done by modeling effective strategies to become a more independent learner such as (a) evaluation or critique of information before accepting its accuracy, (b) translate information to create their own understanding, (c) work out problems on their own before confirming answers with others, (d) opportunities to exchange and evaluate ideas with others. Instructional interventions that improve student use of resources in chemistry could lead to better overall student performance.
