This article reports about a lesson series that focuses on engaging students in sustainability, plastics, and life cycle assessment (LCA). The purpose of the lesson series is to give students insights into sustainability in the context of plastics and to foster awareness of and insights into the benefits of the LCA method. The lesson series…

Despite the substantial progress made to develop evidence-based pedagogical practices that support student learning, many courses are dominated by "traditional" practices such as a passive lecture. Thus, a continued focus on reforming courses is necessary. Here we describe the deliberate practice-driven reform of a large lecture-format…

The research on students' perceptions after implementing a teaching style is recommended due to its potential to inform reformed education. The present study surveyed 319 students and revealed their perceptions of multimedia usage in teaching and learning quantum physics. Among these students, 156 were surveyed after learning quantum physics with…

The purpose of this study was to explore four elementary preservice teachers' (PSTs) learning outcomes based on "affective characteristics," "science knowledge," and "pedagogical content knowledge" during a science methods course that incorporated "explicit instruction on drawing-to-reason" about…

An individual harmonic wave (i.e., having a single frequency and wavelength over all time and space) traveling in a loss-free medium has a single constant speed, which is equal to the magnitude of the phase velocity of the wave. However, when a set of different harmonic waves are traveling in the same direction, they interfere to form wave…

This article analyzes and experimentally verifies the stability behavior of the equilibrium states of a conical pendulum. An analysis of the motion presents that the equilibrium states of the pendulum are determined by the pendulum angular speed. For a given pendulum length there exists a critical angular speed that determines stability…

Points near the top end of a falling rod hinged at its bottom end can fall faster than g. If a rod falls on a frictionless surface then the bottom end slides backwards and the centre of mass falls vertically with acceleration less than g. The effect was simulated by mounting a rod on wheels and filming the result with a video camera. The…

A standard problem for physics students is to calculate or measure the acceleration of an object down an inclined plane. Additional information can be obtained by measuring the angular acceleration as well as the linear acceleration. An experiment is described where a billiard ball was filmed as it rolled down an inclined plane at different…

This study employed a sequential mixed methods explanatory research design to explore the influence of mentoring in the self-efficacy-forming experiences of primary school teachers who participated in a variety of professional development projects on science teaching. In the quantitative phase, survey data drawn from primary school teachers…

Live cell imaging is a standard technique in experimental biology that enables the observation of isolated cells and tissue slices in real time and the testing of cellular responses to changes in buffer composition. However, most live cell imaging devices require the use of dedicated microscopes and/or specialised stage adaptors, and come at a…

Background: Emotional design of multimedia lessons involves adding features that are intended to increase learner enjoyment and promote learning--such as adding narrative, anthropomorphizing non-human elements, and using warm colours. Objective: The present study extends this work to examine the potential of Japanese animation (anime) for…

Most primary school students, although they grasp the scientific concepts of heat convection at the macroscopic level, commonly fail to visualize those concepts. Therefore, our research aims to enact a constructivist teaching sequence (CTS) to restructure students' visualization changes, ultimately enabling them to synergize macroscopic and…

Guided by the 5E framework (Engage, Explore, Explain, Elaborate, Evaluate), a buffer solution courseware was designed using "Articulate Rise," a content authoring tool. It was deployed in a freshman general chemistry course in the April semesters of 2022 and 2023. The courseware was a supplementary resource to support instructor-created…

Resonance is a fundamental chemistry concept first introduced to students in General Chemistry I, reintroduced in Organic Chemistry I, and then utilized throughout other higher-level chemistry courses. A molecule or ion can be said to exhibit resonance when it can be represented by two or more chemical structures (i.e., Lewis structures) that…

The main aims of the present research were to: (1) describe the scientific outputs indexed in the Scopus and Web of Science databases, from now on WoS, regarding the use of comic books as didactic resources in the teaching-learning of the sciences, and; (2) establish the conceptual structure of scientific output regarding the use of comic books as…
