Post Hoc

<p>In an ongoing effort to increase student retention and success in the undergraduate general chemistry course sequence, a fully online preparatory chemistry course was developed and implemented at a large public research university. To gain insight about the efficacy of the online course, post-hoc analyses were carried out in which student performance on final exams, and performance in the subsequent general chemistry course were compared between the online cohort and a previous student cohort who completed the preparatory chemistry course in a traditional lecture format. Because the retention of less academically prepared students in STEM majors is a historical problem at the institution in which the online preparatory chemistry course was implemented, post-hoc analyses were also carried out to determine if this at-risk group demonstrated similar achievement relative to the population at large. Multiple linear regression analyses were used to compare final exam scores and general chemistry course grades between the online and in-person student cohorts, while statistically controlling for incoming student academic achievement. Results from these analyses suggest the fully online course led to increased final exam scores in the preparatory course (unstandardized <i>B</i> = 8.648, <i>p</i> < 0.001) and higher grades in the subsequent general chemistry course (unstandardized <i>B</i> = 0.269, <i>p</i> < 0.001). Notably, students from the lowest quartile of incoming academic preparation appear to have been more positively impacted by the online course experience (preparatory chemistry final exam scores: unstandardized <i>B</i> = 11.103, <i>p</i> < 0.001; general chemistry course grades: unstandardized <i>B</i> = 0.323, <i>p</i> = 0.002). These results suggest a fully online course can help improve student preparation for large populations of students, without resulting in a negative achievement gap for less academically prepared students. The structure and implementation of the online course, and the results from the post-hoc analyses will be described herein. </p>

The Impact

This paper describes the conversion of an introductory computing course to the blended learning model at a small, public liberal arts college. Blended learning significantly reduces face-to-face instruction by incorporating rich, online learning experiences. To assess the impact of blended learning on students, survey data was collected at the midpoint and end of semester, and student performance on the final exam was compared in traditional and blended learning sections. To capture faculty perspectives on teaching blended learning courses, written reflections and discussions from faculty teaching blended learning sections were analyzed. Results indicate that student performance in the traditional and blended learning sections of the course were comparable and that students reported high levels of interaction with their instructor. Faculty teaching the course share insights on transitioning to the blended learning format.

Psychology Course

Students in an introductory psychology course took a quiz a week over each textbook chapter, followed by a cumulative final exam. Students missing a quiz in class could make up a quiz at any time during the semester, and answers to quiz items were available to students prior to the cumulative final exam. The cumulative final exam consisted of half the items previously presented on quizzes; half of those items had the response options scrambled. The performance on similar items on the cumulative final was slightly higher than on the original quiz, and scrambling the response options had little effect. Students strongly supported the quiz a week approach.

Introductory Biology Course

We assessed the performance of students with a self-reported conflict between their religious belief and the theory of evolution in two sections of a large introductory biology course (N = 373 students). Student performance was measured through pretest and posttest evolution essays and multiple-choice (MC) questions (evolution-related and non-evolution-related questions) on the final exam and posttest. The two class sections differed only in exam format: MC with or without constructed-response (CR) questions. Although students with a reported conflict scored significantly lower on the final exam in the MC-only section, they scored equally well in the MC+CR section, and all students in the MC+CR section performed significantly better overall. As a result, (1) a religious conflict with evolution can be negatively associated with student achievement in introductory biology, but (2) assessment with constructed response was associated with a closed performance gap between students with and without a conflict. We suggest that differences in exam format and focus on student acceptance of evolution (either evidence-based or opinion), rather than reported conflict, may contribute to the inconsistencies in student learning of evolution across research studies, and that CR questions may help students overcome other obstacles to learning evolution.

Abstract Background Physiology is a subject that is considered difficult; it is associated with academic failure and causes high levels of stress and anxiety in students. Methods This study compared the effectiveness of a traditional lecture-based methodology with that of a flipped classroom scheme focusing on cooperative ludic learning among gastrointestinal and renal physiology students. Two groups were subjected to these two different methods to teach gastrointestinal and renal physiology content divided into 14 topics. Additionally, two subgroups were identified in each group: entrants and repeaters. There were no differences in age or gender between the subgroups. Results Levels of self-perceived stress (measured by the SISCO scale), biological stress (measured by awakening salivary cortisol levels), and anxiety (measured by the Zung scale) were high in all of the students; the cortisol levels increased in the entrants and some of the scores in SISCO scale increased in the repeaters, throughout the study. The self-reported study time was longer in the students subjected to the flipped classroom-based method. The final exam results were better only in the new students facing the flipped methodology, but not in the repeaters, who scored lower on the final evaluation. The quantitative and qualitative assessments completed by the participants regarding the different aspects of the flipped-classroom-based methodology were favorable; however, the participants believed that traditional lectures should be maintained for specific topics. Conclusions A methodology based on flipped teaching was an effective strategy to improve academic performance ingastrointestinal and renal physiology, but only in new students.

The purpose of this study was to assess the effect of flipping the classroom on final exam scores in a terminal general education college mathematics course for a diverse student population. We employed a quasiexperimental design. Seven instructors collectively taught 13 sections of each pedagogy (flipped/traditional). Six hundred thirty-two students participated. Common final exams were graded concurrently. Mixed-model analyses were performed. Students in flipped sections scored 5.1 percentage points higher on average than those in traditional sections (p = .02) when controlling for math SAT and financial aid status, an improvement of 7.8 points among Black students (p < .01) and 1.0 points among Whites (p = .67). The estimated average difference between White and Black students, conditional on covariates, was 5.2 percentage points in traditional sections (p < .01) and –1.6 in flipped sections (p = .39). The 6.8-point difference in achievement gap between pedagogies was statistically significant (p < .01). Flipping the classroom was associated with improved student performance, particularly among Black students.

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.

Process-oriented guided-inquiry learning (POGIL), a pedagogical technique initially developed for college chemistry courses, has been implemented for 2 yr in a freshman-level anatomy and physiology course at a small private college. The course is populated with students with backgrounds ranging from no previous college-level science to junior and senior biology, biochemistry, and forensic science majors. Fifty percent of the lectures in the course were replaced with POGIL activities, performed in class by students working collaboratively in small groups. The introduction of POGIL pedagogy into the second half of a two-semester anatomy and physiology course significantly improved student performance on summative evaluations. Overall course scores increased from a mean score of 76% to 89% in the three semesters after POGIL was introduced. Performance on the same multiple-choice final exam rose from a mean of 68% to 88% over the same time period. Most significantly, the rate of students earning a D or F in the course was halved in the first two semesters after POGIL was introduced and was 0% in the third semester. Student satisfaction with the method was high, and most students perceived the value of this form of instruction.
