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…

Students spend much time in doing their physics homework. Whether this effort results in deep learning depends on the quality of the mere homework. Therefore, we designed a minds-on simulation-based approach to physics homework and conducted a pretest-posttest quasi-experiment to compare its effectiveness to the effectiveness of traditional…

Learning in the classroom is highly influenced by the experiences a teacher plans for students. Concerned that students were not achieving adequate conceptual knowledge during traditional undergraduate physics courses, the authors used the Making Sense of SCIENCE curriculum to tailor a course for 21 pre-service elementary teachers at the…

We describe an educational activity that can be completed with mobile media devices in order to understand the working principle of a pair of tuning forks, from the Historical Collection of Physics Instruments of the University of Palermo, and how they were used to explain acoustic interference and beats with the Lissajous optical method. This…

Argumentation is central to science learning. Students in every domain of science should have the opportunity to develop the ability to think and act in ways associated with argumentation. When engaged in argumentation, students learn how to puzzle through problems, to see multiple ways of finding solutions, to gather and evaluate evidence on…

The aim of this study was to determine the effect of model-based cooperative (Reading Writing Application) and individual learning methods on conceptual understandings of pre-service science teachers and to eliminate their misconceptions related to gases. For this reason, a pretest/post-test non-equivalent comparison group design was applied…

In this work, we will describe a Peer Project Learning assignment focused on the STEM project-based learning activities where students build a custom board game with a series of constraints that guide them to learn (and later teach) about the main concepts of an electromagnetism physics course for undergraduate students.

Basic science courses, such as physics, are fundamental to precollege studies. For instance, in different engineering applications, electricity and magnetism require comprehending subjects such as electrical circuits and power electronics. However, abstract concepts such as electric or magnetic fields are often difficult to explain without visual…

The oscillations of one mass "m" suspended between two different springs, assuming a friction force proportional to the velocity [minuscule], have been studied. For this purpose, an assembly for this system has been made. The movement of the mass is recorded with a smartphone and analysed with "Tracker." It is obtained that the…

Enzymes are organic molecules known for their catalytic nature because they accelerate metabolic reactions in organisms. The study of enzyme functions and modes of action is essential to understand Biochemistry. This study aimed to analyse the acetylcholinesterase enzymatic activity, as well as the enzymatic inhibition mechanism in practical…

If the concepts used in curriculum, textbooks, classroom teaching, and assessment are not consistent, students may have difficulty in understanding the concepts of science correctly and this may lead to the formation of misconceptions. The purpose of this study is to measure the alignment of science concepts by analyzing the semantic networks of…

The properties and functions of complex systems apply across a variety of domains of science and are at the heart of the solutions to many global crises facing the world today. As such, understanding of complex systems has been increasingly recognized as a core goal of science education. Learning about complexity-related concepts and phenomena is…

To stimulate the intellectual curiosity of elementary school students, we conducted a workshop in distance education aimed at exploring the microscopic world inside a cell. In this workshop, elementary school students motivated to learn more on the subject of science analyzed movies of the Brownian motion of micrometer-sized particles suspended in…

Science reading activities play an important role in shaping and constructing new knowledge. The enactment of these activities was commonly used to develop scientific literacy and enhance students' understanding. However, lack of the study focuses on reducing misconceptions and developing argumentation skills. This study, therefore, aimed to…

This study aims to determine pre-service science teachers' metaconceptual activities about the design of processes to teach science concepts in their pre-active phase. A single-case design was used. The eight pre-service science teachers participated in this study. An activity journal and an instruction process evaluation developed by the…
