This study investigated evidence of how students' mental models of fundamental kinematic relations evolved (i.e., developed cognitively over time) as observed during an introductory course in calculus-based classical mechanics. The core of the curriculum is based on a claim known as Galileo's principle of relativity. The course material comprised…

In order to characterize students' risk assessment explanations based on the Geohazard Risk Framework, which describes four key elements of risk for high school science education, we investigate whether student explanations include the following risk elements: scientific factors, impacts, human influences, and likelihood. This study uses the…

This study aims to investigate the effects of an integrated Science, Technology, Engineering, and Mathematics (STEM) unit designed around the issue of sulfide mining on middle school students' socioscientific reasoning competencies (i.e., complexity, perspective taking, inquiry, skepticism, affordances of science). More specifically, students'…

The diversity of scientific methods has received widespread attention and recognition in recent years. Brandon's Matrix illustrated four categories of scientific methods, which was applied to establish the analytical framework of this study. This paper adopted content analysis to investigate how the diversity of scientific methods is represented…

Purpose: A health learning program relying on the scientific method was designed to promote reducing the intake of foods high in sugar, sodium and saturated fat in a group of school-aged children. Design/methodology/approach: The scientific method was a core approach for creating intervention activities. We conducted mixed-methods research…

This study explores machine learning (ML) for assessing elementary students' scientific argumentation skills, addressing the inefficiency of traditional teacher-based evaluations. We developed tailored test questions and scoring rubrics, collecting data from sixth-graders in China. Four shallow learning algorithms (Polynomial Naive Bayes, k-NN,…

This study tracked pre-service science teachers (PSTs) over 3 years as they completed required science courses (e.g., chemistry, biology and science and technology laboratory courses). The PSTs' use of argument, representations, and reasoning were examined (1) to determine the coherence within and between these and (2) examine the relationship…

Biochemistry and molecular biology is an experimental discipline and therefore training students in experimental techniques and data analysis is an essential component of undergraduate degrees. However, the amount of practical work may be limited by financial constraints and can vary considerably in the quality of the student experience. We were…

A critical skill that biochemistry students must develop is the interpretation of molecular images, ranging from macromolecular representations to the chemical structures of the building blocks that comprise them. Such analysis requires biomolecular visual literacy, which is not often explicitly taught, and can be challenging for instructors to…

Students develop process skills through repeated practice of data interpretation, problem solving, and critical thinking. The primary literature provides a rich source of data and application problems to engage students in this practice within the context of chemistry content knowledge. However, most existing classroom activities based on the…

Elemental analysis is performed in a variety of ways in food and environmental sciences; thus, we have designed an activity in which students gain experience with research-level lab techniques in a real-world context through the quantification of key elements in breakfast cereals using microwave plasma optical emission spectroscopy (MP-OES). The…

Introduction: Critical thinking is a highly-valued skill in higher education, even though there are few studies that demonstrate its effectiveness on scientific skills of pedagogy students. The purpose of this study was to analyze the effect of a critical thinking program (PENCRIT-RC) on inquiry and probabilistic reasoning skills in pedagogy…

The purpose of this study was to investigate whether the course, Scientific Inquiry, significantly increased the self-efficacy beliefs of its students. According to Bandura (1977), an increase in self-efficacy could increase the likelihood that teachers implement scientific inquiry in their classrooms. I explored self-efficacy in an effort to…

The goal of this study was to evaluate the effectiveness of organic chemistry textbooks in developing student representational competence skills with eight representations of molecular structure (Lewis structures, Kekulé structures, condensed structures, electrostatic potential maps, skeletal structures, dash-wedge diagrams, Newman projections,…

Machine learning algorithms that automatically score scientific explanations can be used to measure students' conceptual understanding, identify gaps in their reasoning, and provide them with timely and individualized feedback. This paper presents the results of a study that uses Hebrew NLP to automatically score student explanations in Biology…
