Ruomei Gao; Judith Lloyd-Weinstein; Jody Cardinal – Journal of College Science Teaching, 2024
Pedagogical approaches for supporting students' argumentative writing in science laboratories have not been fully established. This article examines the development of argumentative abilities in undergraduate students enrolled in chemistry laboratory courses that employed two teaching sequences: (i) an argumentative writing workshop for conceptual…

Chaumba, Jeff B.; Chaumba, Josphine – Journal of College Science Teaching, 2023
Spatial reasoning is one of the most challenging skills to master in the science, technology, engineering, and mathematics (STEM) fields. This article reports the results of a teaching intervention that involved using wooden blocks to enhance the development of spatial reasoning in an undergraduate-level introductory geology course. Wooden blocks…

Goolsby-Cole, Cody; Bass, Sarah M.; Stanwyck, Liz; Leupen, Sarah; Carpenter, Tara S.; Hodges, Linda C. – Journal of College Science Teaching, 2023
During the pandemic, the use of question pools for online testing was recommended to mitigate cheating, exposing multitudes of science, technology, engineering, and mathematics (STEM) students across the globe to this practice. Yet instructors may be unfamiliar with the ways that seemingly small changes between questions in a pool can expose…

Hallett-Njuguna, Rachel – Journal of College Science Teaching, 2023
Preservice elementary teachers are faced with the daunting task of learning enough about every subject to support their students' development of foundational ideas. Teacher preparation programs and professional development providers therefore have the challenge of supporting those preservice and in-service teachers by providing content and methods…

Patricia Morrell; Adele Schepige – Journal of College Science Teaching, 2023
The purposes of this study were to examine preservice elementary teachers' conception of the water cycle; determine if participating in a conceptual change-based role-play alters these conceptions; and ascertain if any conceptual change brought about by the intervention is lasting. We found that most of our students held naive conceptions of the…

Colin Harrison; Clarke Britton; Hannah Shin; Yassin Watson – Journal of College Science Teaching, 2023
Online laboratories can be an effective way to introduce students to lab concepts while providing flexibility, increased access, and reduced costs. However, online labs might lack the authentic research experience that can be gained by doing hands-on lab work. This study explores student perceptions of an online, inquiry-based introductory biology…

Yuen, Pong Kau; Lau, Cheng Man Diana – Journal of College Science Teaching, 2022
Redox reaction is a core concept in teaching and learning chemistry. This article explores a new method for balancing organic redox reactions that requires the balancing of both atoms and charges. The H+, O, H[subscript 2]O, and e- are used as balanced vehicles in two half reactions. A non-oxidation number approach can be applied to both molecular…

Subramaniam, Karthigeyan; Long, Christopher S.; Harrell, Pamela Esprivalo; Khan, Nazia – Journal of College Science Teaching, 2022
This study investigated the stability and persistence of prospective elementary teachers' conceptual understanding of average speed. A questionnaire containing two questions about average speed was administered to the prospective teachers prior to their admission to an elementary science methods course (pretest) and at the end of the course…

Singh, Mamta – Journal of College Science Teaching, 2022
The study assessed the science teaching confidence of preservice teachers in teaching elementary science by addressing two research questions: (1) Did preservice teachers understand the science concepts well enough to be effective in teaching elementary science content? (2) Did preservice teachers have the necessary science concepts and skills to…

Craig, Erin M.; Galbreath, Sydney; Sorey, Timothy; Ricketson, Derek – Journal of College Science Teaching, 2022
A growing number of Introductory Physics for Life Sciences courses have been developed to prepare biology, premedicine, and prehealth majors for cross-disciplinary connections between physical principles and biological systems. Many students find it challenging to apply idealized algebra-based general physics to more complex biological systems. A…

Moore, Sammi; Gray, Ron; Meilander, Jeff – Journal of College Science Teaching, 2022
Historically, undergraduate anatomy and physiology (A&P) has been a challenging course for incorporating conceptual learning techniques due to large class sizes and an emphasis on content and terminology. The project utilized the Predict-Observe-Explain (POE) strategy to create short activities based on real-world scenarios that incorporated…

Forbes-Lorman, Robin; Korb, Michele; Moser, Amy; Franzen, Margaret A.; Harris, Michelle A. – Journal of College Science Teaching, 2022
Physical and life science disciplines emphasize how basic structural units influence function, yet it is challenging for students to understand structure-function relationships, particularly at molecular scales. Undergraduates in our biology capstone course struggled to connect mutations in a gene encoding a key protein in a cell development…

Arthurs, Leilani A.; Elwonger, Justin; Kowalski, Chelsie M. – Journal of College Science Teaching, 2021
Whether to engage student preconceptions to facilitate conceptual change is an area of debate among conceptual change theorists. Here, we evaluate the efficacy of a preconceptions-based instructional sequence about groundwater previously described by (Arthurs, 2019). To assess the impact this instructional sequence had on facilitating the…

Begg, Meredith; Pierce, Robyn – Journal of College Science Teaching, 2021
Symbols are a cornerstone of the written language of physics and mathematics but inconsistencies in their use pose a challenge to students. This article reports on interviews held with first-year undergraduate physics students, focused on their early experiences with symbols in university physics. Students reported being confused by the symbolic…

Nieberding, Megan; Buxner, Sanlyn; Elfring, Lisa; Impey, Christopher – Journal of College Science Teaching, 2021
An understanding of basic science is central to student success at the university level, even for students who will never work in scientific fields. Our investigation into students' understanding of DNA is part of a larger investigation into students' knowledge and attitudes about science. DNA and the concepts associated with it (e.g., heredity…
