Teaching practices used by teachers influence students' achievement of learning outcomes. These practices may be explored from students' perspectives. Because gender may influence students' perceptions of learning environments, this study explored gender differences in students' perceptions of teaching practices employed in their biology…

Enzymes are nature's catalysts, mediating chemical processes in living systems. The study of enzyme function and mechanism includes defining the maximum catalytic rate and affinity for substrate/s (among other factors), referred to as enzyme kinetics. Enzyme kinetics is a staple of biochemistry curricula and other disciplines, from molecular and…

Testing is a highly important tool, used ubiquitously in academia, to assess student comprehension and understanding of material. Unfortunately, the emphasis placed on test grades has resulted in a modern epidemic of test-related anxiety, which can have adverse health effects on students. Over time, novel testing strategies have been developed to…

Integrating literacy in science and mathematics learning and teaching has been an ongoing endeavour. There are frameworks developed to guide teachers' practices, but little is reported on assessing literacy simultaneously with scientific or mathematical content knowledge. We reviewed the literature on assessing literacy in science and mathematics…

In recent years, single-subject experimental courses have not been able to meet the demands of the comprehensive development of life sciences. This study is based on two fundamental disciplines, molecular biology and metabolomics, with the analysis and intervention of tumor-related genes as the starting point. A comprehensive experimental course…

Problem solving is considered an essential ability for becoming an expert in physics, and individualized feedback on the structure of problem-solving processes is a key component to support students in developing this ability. Problem-solving processes consist of multiple elements whose order forms the sequential structure of these processes.…

In this paper we argue that the complexity of education systems can lead to a lack of coherence in the implementation of policy. More effective educational change requires policymakers and researchers to pay more attention to supporting teachers in classrooms. As an example, we consider decades of research attempts in STEM education to implement…

To potentially engage students in "doing organic chemistry", organic chemistry courses should foreground weaving together structure- and energy-related ideas to construct causal accounts for phenomena. Here, we investigate whether enrolling in an organic chemistry course that places substantial emphasis ([approximately]50% of total…

Pedagogical content knowledge (PCK) is important for teachers' instructional effectiveness. This study investigated the self-reported level of PCK among in-service elementary school science teachers in a municipality in Ghana, examining the overall level of PCK. An In-Service Elementary Science Teachers Self-Reported PCK (IEST-SR-PCK) scale was…

Understanding reaction mechanisms is integral to success in organic chemistry; however, prior research suggests that learners struggle with recognizing the importance of underlying implicit features in reaction mechanisms. Because of this struggle, understanding how learners' reason about reaction mechanisms and developing assessments to elicit…

In this study, we investigated the impact of collaborative learning practices on the academic success of first generation college (FGC) students in one section of a general chemistry course. We implemented group problem solving and group quizzes during the lecture sessions of General Chemistry 1. Our focus was on understanding how FGC students…

The work in this dissertation is presented in two parts. The first part (Chapters 3 and 4) details work relating to students' explanations of reaction mechanisms in organic chemistry. The second part (Chapters 5 and 6) details work relating to the evaluating the uptake of research-based instructional practices in introductory chemistry,…

Local culture has undergone significant shifts and alienations, leading to the neglect of societal values. This situation underscores the need for teachers to be well-prepared to incorporate local wisdom into science education, supporting Cultured-Based Learning. This study, conducted from January to June 2022, aimed to assess the relevance of…

Background: Dialogue between the teaching profession and researchers regarding pedagogical strategy is sometimes problematic. Pedagogy research may benefit from incorporating research methods that can investigate teachers' and pupils' interpretations. Purpose: This research expands the Pedagogy Analysis Framework (Riordan, 2020) by explaining in…

Breadth and depth of curriculum are important for success in science teaching and learning. Curriculum theorists recommend less breadth and more depth than overloaded, superficial science curricula. This study investigates breadth and depth in the official biology syllabi in the seventh to eighth or ninth years in four diverse jurisdictions,…
