Science and engineering practices (SEPs) and crosscutting concepts (CCs) constitute a significant part of "A Framework for K-12 Science Education" (NRC 2012). As teachers, the role of the authors is to highlight the pivotal role that both scientific knowledge and the practices used to generate knowledge play in learning. This article…

Background: In exploratory learning, students first explore a new topic with an activity and then receive instruction. This inversion of the traditional tell-then-practice order typically benefits conceptual knowledge and transfer, but not always. Aims: The current work examines the impact of including contrasting cases in an exploration activity,…

It is often challenging for physics instructors to dedicate time during a course to engage students in developing strategic approaches to learning in addition to problem-solving skills and content knowledge. In this work, we introduce a simple modification to our teaching practice with the purpose of fostering student development of self-regulated…

The ability to express scientific concepts in mathematical terms and integrate scientific and mathematical reasoning about a phenomenon is a foundational cognitive process involved in scientific thinking. This process called "blended math-science sensemaking" (MSS) is a desired skill for all science, technology, engineering, and math…

Given that many models of design-based learning in science education are grounded in forward engineering, in which students are challenged to use the engineering design process to achieve unknown solutions to engineering problems, this study aims to examine the potential of using reverse engineering, as an alternative approach to design-based…

Many students who enroll in a first course in linear algebra major in STEM disciplines other than mathematics. Teachers who serve such students may find it difficult to provide authentic problems from these broader areas that ignite students' interest in linear algebra. In this paper, we highlight an interdisciplinary learning activity that…

It is often necessary to enrich the teaching environment in order for students to learn optics in depth and to interpret the real optical situations with the information they have learned. In this study, a virtual teaching environment was developed using by Algodoo, a 2D simulation software. An eye model was created in order to explain the…

With the development of technology and the normalization of COVID-19 pandemic prevention and control, asynchronous online learning is becoming popular. However, it is still to be explored on how to enhance students' learning engagement and knowledge construction. Based on this, we used content analysis to explore the roles of teaching strategies…

As students learn physics, they are often required to reason about the behavior of macroscopic and microscopic phenomena, and to synthesize prior knowledge from several different areas of physics to construct understanding of new ideas. This can be a tremendously difficult cognitive task for novice students, especially when the unfamiliar…

Igniting excitement for physics in our students is a goal of every instructor. In this paper, we discuss a unique example of the concept of density, a subject that is rarely viewed as intriguing by students. By combining a problem involving dinosaurs and an effective density, our students' interest is often captured through calculating an…

Examination of my students' individual gains on the Force Concept Inventory (FCI) over the course of several semesters led to the realization that student pretest knowledge on certain key questions appeared to be correlated to enhanced gain during the class. Acting under the hypothesis that early intervention aimed at helping the class perform…

Although learning about Nature of Science (NOS) promotes a variety of important outcomes, teachers often lack suitable activities for younger students to effectively address NOS. In this article I elaborate on an NOS activity developed for a teacher professionalisation workshop. The activity is suited for younger students as well, where clear…

This Study aim to investigate the effects of integrated inquiry-based and STEM education learning management on Thai grade 8 students' analytical thinking and learning achievement. The research employed a one-group experimental design with 37 grade 8 students from a public school in Khon Kaen Province, Thailand, selected through purposive…

This study proposed a framework for Virtual Peer Learning by testing Peer Learning Model to engineering students at a university in Manila during the second semester of school year 2021-2022. Guided Peer Discussions method was applied using Virtual Think-Pair-Share and Virtual Gallery Walk as teaching strategies. Convergent-parallel mixed method…

This work presents a sequence to introduce resistive gas sensors in the classroom. It explains the physical principle of the metal oxide semiconductor sensors and exemplifies its real interfacing through the sensor model MQ-2. Besides, it also presents the design of two electronic systems to indicate the level of alcohol concentration in the air,…
