<p> Researchers are learning how to prevent the projected United States shortage of science, technology, engineering, and mathematics (STEM) professionals by retaining more undergraduates in STEM majors. Specifically, since undergraduates generally want to give back to their communities, they experience heightened science career motivation once they "fit" their communal goals with their views of science careers. However, testing the quality of fit is challenging because individuals differ in communal goals and views of science. For the present study, therefore, a person-centered analytical approach was used to identify groups of STEM undergraduates defined by combinations of communal goal endorsement and perceived communal goal affordances. Four groups were identified: Low Incongruent, Moderately Low Incongruent, Average Congruent, and Moderately High Incongruent. Results showed that undergraduates were optimally motivated when both communal goal endorsement and perceived communal goal affordances were moderately high and incongruent. Results also showed that gender and cultural identity could predict group membership.</p><p>

<p>Chemistry students have historically struggled with conceptually understanding organic acidity and oxidation-reduction. Previously dominant approaches towards remediating students? misconceptions has been challenged by Explanatory Coexistence, which eludes to a competition between conceptions held within individuals. Conceptual reprioritization may be associated with the restructuring of conceptual dominance hierarchies, which may occur once a conceptual competition concludes. Investigation of conceptual reprioritizations of general chemistry students? conceptions of organic acidity and oxidation-reduction performed across multiple demographics using Rasch analysis, student interviews and argumentation quality assessment. Student samples belonged to two different general chemistry courses that used different curricula. One used a reform-based curriculum, that compared to the traditional curriculum, focused on discussion and argumentation. Student conceptions were captured, and tracked via repeated measures, using the ACIDI and ROXCI concept inventories. Results indicated both inventories were capable of detecting conceptual reprioritizations after instruction from both curricula. Student achievement was consistent across multiple demographic characteristics. Evidence of argumentation quality and its association with conceptual reprioritizations of organic acidity and dominant, scientifically accepted redox conceptions was collected. Individual interviews suggested conceptual reprioritizations may be attributed to their respective curricula, while also adding insight into thought processes that arose while taking both inventories. Suggestions for future work is also discussed, highlighting the development of community standards, ACIDI and ROXCI responses databases to assess general student representation, and modification of both inventories.

<p> Persistence and retention of college students is a great concern in American higher education. The dropout rate is even more apparent among first-generation college students, as well as those majoring in science, technology, engineering, and math (STEM). More students earning STEM degrees are needed to fill the many jobs that require the skills obtained while in college. More importantly, those students who are associated with a low-socioeconomic background may use a degree to overcome poverty. Although many studies have been conducted to determine the characteristics associated with student attrition among first-generation students or STEM majors, very little information exists in terms of persistence and retention among the combined groups. The current qualitative study identified some of the characteristics associated with persistence and retention among first-generation college students who are also STEM majors. Participants were juniors or seniors enrolled at a regional 4-year institution. Face-to-face interviews were conducted to allow participants to share their personal experiences as first-generation STEM majors who continue to persist and be retained by their institution. </p><p> Tinto&rsquo;s Theory of Individual Departure (1987) was used as a framework for the investigation. This theory emphasizes personal and academic background, personal goals, disconnecting from one&rsquo;s own culture, and institutional integration as predictors of persistence. The findings of the investigation revealed that persisting first-generation STEM majors are often connected to family, but have been able to separate that connection with that of the institution. They also are goal-driven and highly motivated and have had varied pre-college academic experiences. These students are academically integrated and socially integrated in some ways, but less than their non-first-generation counterparts. They are overcoming obstacles that students from other backgrounds may not experience. They receive support from their families and institution, but have diverse academic backgrounds. The findings show that a culmination of many characteristics have enabled the participants to persist and be retained by their institution.</p><p>

<p> Course-based undergraduate research experiences (CUREs) provide authentic research benefits to an entire laboratory course population. CURE experiences are proposed to enhance research skills, critical thinking, productivity, and retention in science. CURE curriculum developers face numerous obstacles, such as the logistics and time commitment involved in bringing a CURE to larger student populations. In addition, an ideal CURE topic requires affordable resources, lab techniques that can be quickly mastered, time for multiple iterations within one semester, and the opportunity to generate new data. This study identifies some of the CURE activities that lead to proposed participant outcomes. Introductory Biology I CURE lab students at Southern Illinois University Edwardsville completed research related to the process of converting storage lipids in microalgae into biodiesel. Data collected from CURE and traditional lab student participants indicate increased CURE student reports of project ownership, scientific self-efficacy, identification as a scientist, and sense of belonging to a science community. Study limitations and unanticipated benefits are discussed.</p><p>

This dissertation is an evaluation of an intervention designed to (a) increase the number of minority students who pursue graduate degrees in Science, Technology, Engineering, and Mathematics (STEM) disciplines, and (b) to develop a cadre of qualified individuals from minority backgrounds who, upon finishing their training, are ready to take positions as faculty members and mentors. The Alliances for Graduate Education and the Professoriate (AGEP) is a program funded by the National Science Foundation (NSF) to support a pathway from undergraduate to graduate school and to a career in the professoriate. AGEP is part of an effort by the U.S. Government to keep the nations' competitive edge; redress historical gender and racial inequalities still prevalent at the higher levels of science and academia; and to use those who have reached the top of their professions as effective role models for the thousands of talented youth who are excluded from STEM fields due to real or perceived social, economic, or cultural barriers. As of September 2012, there were 178 colleges and universities grouped in 37 alliances nationwide and serving approximately 22,000 minority doctoral students. Specifically, this evaluation focuses on one alliance situated in the North Region of the United States, and presents the approaches, rationale, and findings of evaluation activities conducted during 2011 through 2012. The overarching goals of this evaluation were to assist program managers and staff in their efforts to improve the quality and effectiveness of the program, and to provide them with information related to the program's contribution to increasing the recruitment and retention of students from underrepresented minorities (URMs) in STEM graduate programs, their transition into the professoriate, and the strength of the program's theory of change. To achieve these goals the evaluation design included a) the reconstruction of the program's theory, b) a systematic review and meta-analysis of existing research; and c) analysis of primary data collected from a sample of current AGEP students, alumni, faculty, staff, and program officers. Primary data were collected through focus groups, interviews, and electronic surveys for current and former participants. The evaluation found evidence that the North Region program has been largely successful in contributing to the number of URM receiving STEM graduate degrees at both the master's and doctoral levels in North Carolina since its inception in 1999. Those who have received their graduate degrees are employed in academic and non-academic settings as practitioners, researchers, and as university faculty. Probably the most significant weakness was the absence of a systematic or coherent evaluation design of the program that could be found throughout the history of the program.

The purpose of this qualitative study is to understand how women enrolled in undergraduate engineering programs perceive their undergraduate experience in relation to their anticipatory socialization into the engineering profession. The significance of this study rests in the fact that although over the past few decades millions of dollars have been invested to combat the shortage of women entering and persisting in engineering undergraduate programs, very little improvement has yet been achieved. More importantly, although many factors have been determined to perhaps influence the under representation of women in engineering, a clear understanding of why this phenomenon continues has not yet been established. The findings from this study are intended to provide insight into what women in engineering need to succeed and provide clear recommendations for practice and policy to address the issue.

<p> Earlier studies concluded that technology&rsquo;s strength is in supporting student learning rather than as an instrument for content delivery (Angeli &amp; Valanides, 2014). Current research espouses the merits of the Technological Pedagogical Content Knowledge (TPACK) framework as a guide for educators&rsquo; reflections about technology integration within the context of content and instructional practice. Grounded by two theoretical frameworks, TPACK (Mishra &amp; Koehler, 2006; 2008) and Rogers&rsquo; (1983, 1995) theory of diffusion of innovation, the purpose of this mixed-methods research was two-fold: to explore the perceived competencies of tertiary science faculty at higher education institutions with respect to their integration of technology within the constructs of pedagogical practice and content learning and to analyze whether these perceived competencies may serve as predictive factors for technology adoption level. The literature review included past research that served as models for the Sci-TPACK instrument. Twenty-nine professors of tertiary science courses participated in an online Likert survey, and four professors provided in-depth interviews on their TPACK practices. Quantitative analysis of data consisted of descriptive and reliability statistics, calculations of means for each of the seven scales or domains of TPACK, and regression analysis. Open-ended questions on the Likert survey and individual interviews provided recurrent themes of the qualitative data. Final results revealed that the participants integrate technology into pedagogy and content through a myriad of TPACK practices. Regression analysis supported perceived TPACK competencies as predictive factors for technology adoption level. </p>

<p> The purpose of this study was to ascertain the various factors that influenced these first-generation college women as they chose a college and selected a STEM major and subsequently persisted to upper level (junior/senior) status. Twenty-five first-generation college women in STEM majors who attended a research-intensive university in the Midwest were interviewed. Approaching this study using constructivist grounded theory provided the opportunity for deeper insights by examining data at a conceptual level while preserving the voices of the women in this study. The women faced numerous challenges on their journeys, yet they persisted. As the women in this study selected and persisted in STEM, they demonstrated thoughtful determination, experienced shifting identities, established purposeful relationships and applied forward thinking, as they practiced high-stakes decision-making during their journeys. The experiences of these women, namely first-generation women in STEM fields, may inform students, parents, educators, researchers, and policymakers concerned with (a) inspiring students to consider STEM majors, (b) fostering student success in STEM throughout their academic journeys, and (c) ultimately increasing the number of underrepresented minorities and women in the STEM fields.</p>

<p> With the rapid growth of technology and a fast pace society, students have discovered tablet computers, a powerful portable useful device for education. Although studies have shown rapid growth of tablet computer adaptation within education, limited research exists regarding how tablet computers are used for classroom performance, communication, and leadership among college students. The purpose of the study was to explore and understand how college students use tablet computers by interviewing undergraduate and graduate students. Interview results of 20 college students are as follows: (a) students reported that tablet computers were more portable, easier to use, and convenient devices over laptop computers; (b) in regard to classroom performance, students expressed that the use of e-text books combined with tablets was a faster method of searching for a specific subject over standard paperback books; (c) in regards to leadership, many students believed that tablets are only a tool for leaders but not an essential tool for leading people; and (d) in regard to communication, students expressed that tablet computers was an essential tool for team projects and communicating with their professors and peers while on the go. The study includes a discussion of future research in leadership&rsquo;s use of technology in the workplace, college professors&rsquo; perceptions of tablet computers in the classroom, and marketing modern tablet computers.</p>
