General chemistry courses are key gateways for many Science, Technology, Engineering, and Mathematics (STEM) majors. Here, we report on the implementation and evaluation of an adaptive, ALEKS-based online preparatory module (PM) for general chemistry. The module was made available in Summer 2018 at no cost to all students entering any section of general chemistry that fall. Of the 827 students who registered into the PM, 44% fully completed the module, 48% completed part of the module, and 8% did not complete any of the module. Considering students enrolled in first-term general chemistry, we find a marked increase in ACS final exam percentile for students who completed more than 50% of the module. This is suggested to reflect the self-selection of users who were highly motivated and/or likely to succeed in the course, a hypothesis supported by an analysis using an internal diagnostic metric, the predicted first-year quality point average (PQPA). To examine longer term impacts of the PM, we examined performance in subsequent chemistry courses, through second-semester organic, and found that students completing more than 50% of the module outperformed their counterparts across all courses, with the gap largest in first semester general chemistry and narrowing across subsequent courses. Finally, we surveyed students in summer 2020, two years after the PM offering. The survey indicated overall satisfaction with the PM. For students who did not complete the module, primary reasons given were difficulty (29% of respondents) and insufficient time (46%). As the module did not proportionally benefit the target group of underprepared or at-risk students, we suggest tweaks for future implementations.

Completion of a first-semester chemistry (Chem I) course lays the foundation for understanding second-semester chemistry (Chem II) topics. The purpose of this study is to evaluate the influence of basic arithmetic skills on students’ Chem II success in understanding mathematics-grounded concepts (e.g., solutions and aqueous reactions, kinetics, equilibrium, acids and bases, solubility and equilibria, thermodynamics, electrochemistry, and nuclear chemistry). Previous studies suggest a strong correlation between arithmetic preparation and performance in general chemistry courses, though few have focused on the second-semester course. In this investigation, researchers from six higher-education institutions in Texas, USA of different sizes and with student bodies of different diversities have collaborated to determine whether the Math-Up Skills Test (MUST) is able to reliably identify at-risk students from a population of n = 1599 at the beginning of a Chem II course.

The Impact

Many students transitioning from high school to college are faced with challenges of getting acclimated to college life and managing their time and heavy course load that is cognitively demanding. Students planning to major in science, technology, engineering, and mathematics (STEM) programs in the United States are mostly required to enroll in general chemistry courses as prerequisites. Unfortunately, these courses are among the STEM gateway courses in which many first-year students struggle to get through, or are weeded out. This is partly due to the use of ineffective study strategies that require more than rote memorization, a common learning approach in high schools. One way to prepare first-year college students for STEM trajectories is by teaching them metacognitive strategies early in their study programs to enable early adoption and sustainability of metacognition knowledge and metacognition regulation skills as they progress to the advanced courses. While a handful of studies have investigated study strategies among students in the general chemistry courses as well as the impact of metacognitive activities on student performance in chemistry, very few in-depth qualitative studies investigating the influence of explicit teaching of metacognition on students’ study strategies have been reported. Using open-ended questionnaires, this unique study investigated general chemistry students’ study strategies that they employed prior to a 50 minute metacognition lesson; strategies they reported to have gained from the instruction; and the influence of the metacognition instruction on students’ study strategies and performance in the final exam. Findings indicated more reported use of rote memorization over higher-order study strategies prior to the metacognition instruction, but more reported gains on higher-order study strategies and fewer strategies related to rote memorization immediately after the metacognition instruction. Furthermore, 67% reported a positive influence of the metacognition instruction on study strategies, with 7% lower DFs in the final exam compared to those who reported ‘no influence’. Findings revealed that most general chemistry students were unaware of effective study strategies; thus, there is a critical need to explicitly teach students in general chemistry courses metacognitive strategies.

For six semesters, activities have been incorporated into first year general chemistry courses in an effort to build student conceptual chemistry knowledge. The activities follow a learning cycle pedagogy (similar to Process Oriented Guided Inquiry Learning or POGIL activities) and consist of guiding questions involving animations, models, simulations, or a data set and are completed by students working in groups. The efficacy of the learning cycle approach and learning outcomes from POGIL and other similar initiatives have been well studied; however, examining how scaffolding in chemistry learning cycles can improve learning outcomes has not been well studied. In Fall 2016, an activity was implemented in a first semester general chemistry course that focused on energy changes during bond breaking and bond making. The data showed that, even after working with the PhET Atomic Interactions simulation guided by the activity, about half of the students in the sample (N = 55) still thought bond-breaking was an exothermic process, even though they collected data from the simulation that indicated otherwise. After analyzing student answers, the activity was redesigned to increase scaffolding and improve concept development. Students’ performance improved greatly with the implementation of the second activity with 82% of students (N = 34) able to identify and distinguish between exothermic and endothermic processes. Results have implications for applying research-based techniques to activity development to improve students’ conceptual understanding in chemistry.

Math Aptitude

Students who score within the bottom quartile on cognitive measures of math aptitude have been identified as at-risk for low performance in chemistry courses, with less attention as to why such differential performance persists. At-risk students struggle most differentially on assessment items related to the mole concept and stoichiometry. An exploration as to the nature of the differential performance observed became of great interest as the assessment of these topics rarely progresses beyond multiplication or division, and at-risk students who achieved proficiency with the mole concept and stoichiometry had no noticeable gaps in academic chemistry performance when compared to students scoring in the top three quartiles of math aptitude. Thus, students in first-semester general chemistry were surveyed to describe their solution processes toward assessment items involving the mole concept and stoichiometry. Three hundred and forty-eight students responded to all survey prompts with 101 identified as at-risk. Findings suggest that while all students were observed to struggle in the conceptualization of the algorithms by which they execute solution processes, not-at-risk chemistry students were more likely to achieve correct answers via chemically implausible solution pathways. Rather than suggest the removal of assessment practices involving algorithmic, multiple-choice assessment on these topics, the implications include practical suggestions and opportunities for further research toward improving the equitability of measures used to assess proficiency with stoichiometry.

College Calculus

This study investigated the effects of various levels of secondary school calculus experience on performance in first-year college calculus, with focus on student performance on conceptual and procedural exam items. Analysis of covariance, with mathematics SAT score as a covariate, was employed to explore differences among four groups of students. Students who had a year of secondary school calculus, advanced placement or otherwise, differed significantly in performance from students who had either no calculus or a brief introduction to calculus prior to college. A brief secondary school introduction to calculus, in comparison with no secondary school calculus, provided an initial advantage in the college course. This slight advantage reappeared on the final exam and on the procedural subscale of the final exam. Students who had studied a full year of secondary school calculus performed significantly better than other groups throughout the first-semester course. The advantage was revealed more strongly in procedural than in conceptual items. There were no significant differences among the four groups of students on outcome measures in the second-semester course. Students with more secondary school calculus background were more likely to continue into the second semester of college calculus.

Using a Scholarship of Teaching and Learning lens, this study systematically examined if a targeted intervention in at-risk students within a science, technology, engineering, and mathematics (STEM)-based physiology program would elicit positive student perceptions and higher retention rates into the second year. Those students who were considered at risk for attrition (retention; n = 82) were compared against a control group (non-retention; n = 165), and outcomes were evaluated with an End-of-Semester Survey and university enrollment data. Students in the retention group reported more favorable responses to questions pertaining to a first-year seminar course and academic advising. By the start of the following (spring 2019) semester, 48 students transferred out of the program (20%) with little difference between groups (non-retention 19%; retention 22%). At the start of fall 2019 term, 55% of the 2018 freshman class were retained within the program (non-retention 66%; retention 39%), and 85% were retained within the university (non-retention 91%, retention 74%). The intervention was successful in eliciting positive student perceptions of the major, but did not improve retention of at-risk students within the physiology major.

Purpose: Organic chemistry has been shown to correlate with academic success in the preclinical years of medicine, dentistry, and graduate physiology. The purpose of this study is to examine the relationship between undergraduate organic chemistry grades and first-semester biochemistry grades at a Midwest chiropractic doctoral program. Methods: Students enrolled in a first-semester biochemistry course who had completed the prerequisite courses in organic chemistry offered at this same institution were entered into the study. The total grade for each of the three courses was calculated using the midterm and final exam raw scores with a weighting of 50% each. Analysis consisted of obtaining correlation coefficients between the total grades of organic 1 with biochemistry and organic 2 with biochemistry. Using the biochemistry total grade, the students were divided into quartiles and course grades for both organic chemistry 1 and 2 were calculated. Results: For the 109 students in the study, the correlation coefficient between the biochemistry and organic chemistry 1 and biochemistry and organic chemistry 2 courses was r = 0.744 and r = 0.725, respectively. The difference in organic chemistry grades between those in the first and fourth quartiles was 63.2% and 86.9% for organic chemistry 1 (p < .001) and 60.9% and 79.4% for organic chemistry 2 (p < .001). Conclusion: This study shows that organic chemistry can be used as an indicator of future academic success in a chiropractic biochemistry course. Knowledge of such a relationship could prove useful to identify students who may potentially run into academic difficulty with first-year biochemistry.

Scientific and innovative society can be produced by giving priorities in Science, Technology, Engineering, and Mathematics (STEM) as emphasized by Malaysian Higher Education Blueprint (2015-2025). STEM need to be implemented at higher education because universities need to produce competent graduates to support economy growth and sustainable development. Learning STEM through Problem Based Learning might allow the undergraduates to become more enthusiastic when problem-based instruction is incorporated with STEM by implementing teamwork and problem-solving techniques to engage the first-year undergraduates fully with the learning. This study was conducted to investigate whether Integrated STEM Problem Based Learning module could enhance and retain the interest towards genetics concepts among first-year undergraduates. Topics in genetics was considered difficult not only to teach but also to learn. In this research, to overcome the genetic concepts learning difficulties, genetic related topics were chosen to introduce STEM through problem-based learning approach, which might help first-year undergraduates to acquire deep genetic content knowledge. This is very vital for the first-year undergraduates, as the knowledge gained in their first semester will be applied in the upcoming courses in their entire undergraduates’ programs of study. A Pre-Experimental research design with one group-posttest design was applied. A total of 50 participants who are first-year undergraduates from Faculty of Biology from one of the public universities in Malaysia were involved. The Genetics Interest Questionnaire used to study if the STEM Problem Based Learning module could enhance and retain the interest towards genetics concepts. The research has proven that Integrated STEM through problem-based learning approach could enhance and retains the interest in learning genetics concepts among first-year undergraduates.

Although science, technology, engineering, and mathematics (STEM) majors remain male dominated, women’s greater enrollment in STEM is one of the greatest transformations to occur in U.S. higher education in the past half century. But to what extent have women’s gains in STEM enrollment translated to greater parity in labor market outcomes? Although the challenges women face in STEM have been well documented, questions about the influence of gender for STEM employment and earnings differences remain. In the present research, the authors use data from recent birth cohorts in the American Community Survey between 2009 and 2018 (starting with the first year college majors were available in the survey) and a reweighting technique from labor economics to track the evolution of gender inequalities in STEM employment and earnings inequality among STEM work at the onset of labor market entry. Even among a sample expected to produce highly conservative gender differences, sizable gender inequalities in STEM employment are observed. The authors show that despite women’s gains in STEM education among recent cohorts, women with STEM degrees face employment prospects in STEM work that more closely resemble those of men without STEM degrees than men with STEM degrees. Moreover, although modest gender earnings gaps eventually emerge for those without STEM degrees, large gaps occur at the outset of employment for STEM workers. Thus, although STEM education provides important opportunities for women’s earning potential, it may be less effective in itself to address significant gender inequalities among STEM employment.

Retention And Graduation Rates

The mission of the Virginia Commonwealth University Louis Stokes Alliance for Minority Participation (VCU LSAMP) program is to increase the retention and graduation rates of students from underrepresented racial and ethnic groups in science, technology, engineering, and mathematics (STEM) majors and those who matriculate into graduate programs. VCU LSAMP offers a hybrid summer transition program (HSTP) focused on facilitating the high school to college and two-year to four-year college transition process for students majoring in STEM disciplines. The goals of the program are to 1) build community among a cohort of students, 2) orient students to VCU, 3) prepare students for the academic rigors of their first year in a STEM discipline at VCU, 4) expose students to opportunities and careers in STEM, 5) engage them in the VCU LSAMP program, and 6) provide financial support. Five distinct components of the VCU HSTP are 1) a six-week online summer component, 2) a 1 week on-campus orientation, 3) a Design Project Challenge, 4) a transfer student track, and 5) an academic year component. Evaluation data reveals that the HSTP assisted participants with adjustment to the college schedule and setting, facilitated the formation of study groups, and increased overall motivation to graduate. The online courses helped familiarize students with both the academic topics in their chemistry and mathematics classes and the behaviors and norms of STEM majors. On average, participants in the HSTP had higher retention (85%) and graduation (73%) rates when compared with their peers (81% and 64%, respectively). Furthermore, those students who complete the online classes’ requirements had a higher probability of receiving a grade of B or better in their first mathematics or chemistry class.
