Through Preschool and Foundation Level, children are confident in their knowledge about rocks. Five- to six-year-olds have firm ideas on what they consider rocks are and where they might be found (Preston, 2018). With the exception of children who are avid rock collectors, such knowledge usually comprises general, inconsistent ideas formed from…

Mathematical reasoning with algebraic and geometric representations is essential for success in upperdivision and graduate-level physics courses. Complex algebra requires student to fluently move between algebraic and geometric representations. By designing a task for middle-division physics students to translate a geometric representation to…

Controversies in science are an essential feature of scientific practice: defined here as current problems that are unresolved because there are no accepted procedures by which they can be resolved or there are differing assumptions that affect the interpretation of evidence. Although there has been much attention in science education literature…

The focus of this article is to expand María del Mar Aragón, José Antonio Acevedo-Díaz and Antonio García-Carmona's paper "Prospective Biology teachers' understanding of the nature of science through an analysis of the historical case of Semmelweis and childbed fever" by focusing on the discussion about teaching non-epistemic aspects of…

This article presents a qualitative study of the understanding of various epistemic and non-epistemic aspects of the nature of science (NOS), based on analysis of the historical case of Semmelweis and childbed fever. To this aim, an activity was designed which consisted of: (1) reading of a narrative of the case without instruction and discussion…

This article concerns a lacuna in chemistry students' reasoning about chemical bonding. Although chemistry students are familiar with the charges that make up the atom--both positive and negative--they refer only to the attraction between unlike charges. Specifically, they ignore the repulsion between the positive nuclei. We named this disregard…

In this qualitative study, we examined the process of active learning from the perspective of undergraduate students in a high-enrollment introductory biology class. Eight students participated in a series of five interviews throughout the semester that examined their experiences during and after class. Grades were collected for each student at…

Reported herein is a multidisciplinary experiment for senior-level undergraduate teaching laboratories in the synthesis of the analytes acetaminophen and phenacetin; the fabrication of paper-based devices, using eyeliner, acrylic spray paint, or wax-printing, for sensing of those analytes; and the use of the newly fabricated devices for successful…

Recent educational research emphasizes the importance of personal social cognitive beliefs and metacognitive knowledge and skills for achievement in science as well as retention in the field. In this project, a mandatory evening tutorial program was developed to provide direct instruction in metacognitive skills for first year students enrolled in…

Chemistry laboratories ordinarily involve a number of visual observations and require qualitative and quantitative explanations of these observations. A student with blindness at Truman State University successfully completed the laboratory portion of the non-majors liberal arts chemistry course with the assistance of a senior undergraduate…

Students always encounter difficulties in studying biochemical pathways. They are especially weak in understanding the relationships between metabolic pathways and their integration because these pathways are always taught one-by-one in class. In the past, various online resources have been developed to facilitate students' understanding toward…

Biochemistry textbooks often provide a disconnected, highly mathematical, and decontextualized treatment of thermodynamic and kinetic principles, which renders topics like protein folding difficult to teach. This is concerning given that graduates entering careers, like the pharmaceutical industry, must be able to apply such knowledge and related…

There have been significant increases in the number of students studying physiology in the Bachelor of Science degree-program at our university. We thought that physiology prerequisites for graduate programs in medicine and allied-health areas were facilitating these increased numbers. Undergraduate physiology students were surveyed about their…

Health sciences students need strong communication skills so that they can engage patients, explain concepts and justify medical procedures. For 3% of their final mark, 547 students studying the anatomy and physiology of the immune system were assigned the creation of a one-page brochure to help parents understand the importance and mechanism of…

In quantum mechanics, probability amplitudes are complex numbers and the relative phases between the terms in superposition states have measurable effects. This article describes an investigation into sophomore- and junior-level students' reasoning patterns in relating relative phases and real-world quantum phenomena. The investigation involved…
