ABSTRACT As a validated assessment, the Microbiology for Health Sciences Concept Inventory (MHSCI) is a valuable tool to evaluate student progress in health sciences microbiology courses. In this brief analysis, we survey MHSCI faculty users and report student MHSCI scores to determine the impact on student learning gains of the COVID-19 pandemic and subsequent quarantine in spring 2020. Although a majority of students reported moving to a fully online lecture and lab microbiology course in the spring 2020 semester, there was no statistically significant impact on student outcomes reported by the MHSCI, and by some measures, student learning gains increased in the semester students moved to online learning. Further research is necessary to determine the continuing impact of online lecture/lab courses on student outcomes on the MHSCI. Our analysis of data from spring 2020 shows that the MHSCI is still a statistically reliable measure of student misconceptions and overall difficulty scores for each item on the MHSCI was unchanged due to the pandemic.

Application of the Microbiology Concept Inventory to improve programmatic curriculum
ABSTRACT The Microbiology Concept Inventory is an assessment tool derived from the fundamental statements created by the American Society for Microbiology. This two-tier, multiple-choice question inventory requires students to choose the most correct answer for each question and provide a brief justification of their reasoning. Educators can utilize this tool to identify common misconceptions held by students and adjust curriculum to address and prevent the persistence of student misconceptions. Over the course of 5 years, the Microbiology Concept Inventory was annually administered to undergraduate students enrolled in entry-level, mid-level, and senior capstone microbiology courses at a mid-western rural university. Analysis was completed to compare course, year, majors and minors, gender, ethnicity, and cumulative GPA. Results of this study showed a significant difference in Microbiology Concept Inventory scores between students with high cumulative GPAs (3.5–4.0) and students with comparatively lower cumulative GPAs (2.5–2.99, 3.0–3.49). Results between the other demographic categories revealed statistically different scores in favor of white students, but no differences in scores between genders. The results suggest evidence of ethnic bias, but no gender bias as measured by the Microbiology Concept Inventory. Additionally, significant differences in scores across cohorts are indicative of improvements in the curricula due to prior targeted changes. Analysis of concept inventory results can guide curriculum changes for course instructors. Implementation of curriculum changes can enrich students’ academic success.

Students come to learning in engineering classrooms with misconceptions about the concepts covered in engineering course contents. However, instructional efforts often do not effectively address misconceptions in students’ prior knowledge. Concept inventories (CIs) are often relied upon to identify misconceptions in students’ prior knowledge. However, many instructors never benefit much from using CIs because they lack either the know-how, time commitment, or statistical skills required to use them efficiently and effectively. Furthermore, there sometimes are ambiguities about how to interpret students’ CI scores. The Electric Circuit Concepts Diagnostic (ECCD) project team will address these limitations of CIs by creating a web-based electric circuit concept inventory that: (i.) provides an immediate and multipurpose feedback system for reporting about students’ circuits and electricity prior knowledge; (ii.) differentiates, with a high probability, between a lack of prior knowledge and misconceptions; and (iii.) uses a scheme of multidimensional knowledge profiles to report on students’ prior knowledge and misconceptions. The project will integrate the affordances of cognitive diagnostic modeling (CDM), multitier testing frameworks, and computer-assisted testing to realize these project objectives. This work-in-progress report introduces the objectives of ECCD inventory to the ECE research and teaching community.more » « less

This study investigates how Learning Assistants (LAs) and related course features are associated with inequities in student learning in introductory university physics courses. 2,868 physics students’ paired pre- and post-test scores on concept inventories from 67 classes in 16 LA Alliance member institutions are examined in this investigation. The concept inventories included the Force Concept Inventory, Force and Motion Conceptual Evaluation, and the Conceptual Survey of Electricity and Magnetism. Our analyses include a multiple linear regression model that examines the impact of student (e.g. gender and race) and course level variables (e.g. presence of LAs and Concept Inventory used) on student learning outcomes (Cohen’s d effect size) across classroom contexts. The presence of LAs was found to either remove or invert the traditional learning gaps between students from dominant and non-dominant populations. Significant differences in student performance were also found across the concept inventories.more » « less

Mechanics instructors frequently employ hands-on learning with goals such as demonstrating physical phenomena, aiding visualization, addressing misconceptions, exposing students to “real-world” problems, and promoting an engaging classroom environment. This paper presents results from a study exploring the importance of the “hands-on” aspect of a hands-on modeling curriculum we have been developing that spans several topics in statics. The curriculum integrates deep conceptual exploration with analysis procedure tutorials and aims to scaffold students’ development of representational competence, the ability to use multiple representations of a concept as appropriate for learning, problem solving, and communication. We conducted this study over two subsequent terms in an online statics course taught in the context of remote learning amidst the COVID-19 pandemic. The intervention section used a take-home adaptation of the original classroom curriculum. This adaptation consisted of eight activity worksheets with a supplied kit of manipulatives and model-building supplies students could use to construct and explore concrete representations of figures and diagrams used in the worksheets. In contrast, the control section used activity worksheets nearly identical to those used in the hands-on curriculum, but without the associated modeling parts kit. We only made minor revisions to the worksheets to remove reference to the models. The control and intervention sections were otherwise identical in how they were taught by the same instructor. We compare learning outcomes between the two sections as measured via pre-post administration of a test of 3D vector concepts and representations called the Test of Representational Competence with Vectors (TRCV). We also compare end of course scores on the Concept Assessment Test in Statics (CATS) and final exam scores. In addition, we analyze student responses on two “multiple choice plus explain” concept questions paired with each of five activities covering the topics of 3D moments, 3D particle equilibrium, rigid body equilibrium (2D and 3D), and frame analysis (2D). The mean pre/post gain across all ten questions was higher for the intervention section, with the largest differences observed on questions relating to 3D rigid body equilibrium. Students in the intervention section also made larger gains on the TRCV and scored better on the final exam compared to the control section, but these results are not statistically significant perhaps due to the small study population. There were no appreciable differences in end-of-course CATS scores. We also present student feedback on the activity worksheets that was slightly more positive for the versions with the models.more » « less
