In this study, the primary goal was to enhance the knowledge and awareness of 4th-grade primary school students regarding global pandemic diseases and methods of safeguarding against worldwide epidemic diseases which are socio-scientific issues. To achieve this goal, two activity modules tailored for 4th-grade students were created. These…

Laboratory work has been a common element of science courses at university level for around two centuries, but its practice has been criticised by scholars in the field and related stakeholders. Mainly on a rationale of financial justification and educational efficacy, more evidence for learning has been called for. The aims of this systematic…

Ion transport, involving the diffusion and migration of ions within the electrolyte, stands as a fundamental concept in electrochemistry and serves as the driving force for electrochemical reactions. Electric double layers are critical in the fields of electrochemical energy storage and chemical conversion, constituting a central focus of…

Chile is home to most of the world's largest telescopes, and astronomy research is robust in the country. However, astronomy education in Chile is much less mature. As an effort to increase its quality and coverage, more astronomy K-12 teacher professional development (PD) has been offered in Chile in the last decade, but the results of these…

Action research (AR) has long been promoted as a way teachers can improve their practice and increase their understanding of their educational situations. In this article we examine the impact of AR on science teacher education through a critical review of the literature. We sought to identify the goals and purposes of the AR, its mode, and the…

A large-enrollment, introductory physics laboratory course at the University of Colorado Boulder has undergone a recent transformation to help students' develop lab skills and better align students' views and beliefs about experimental physics with those of expert experimental physicists through engagement with authentic scientific practices. We…

Innovative activities carried out during school laboratory sessions include 'flipped learning' (FL), which is an interactive learning environment where the teacher guides students learn individually. This study examined the impact of the adoption of the FL approach on the academic performance of 2nd year science student teachers enrolled in the…

In the present research, the "DNA Model with Clothespins" activity was designed to teach the subjects of nucleotide, DNA, and DNA replication, which are abstract subjects of science. The aim of the research, which was carried out with 20 students in 8th grade, was to examine the effects of the activity on students' achievement on the…

Over a decade has passed since faculty members' goals for the undergraduate chemistry instructional laboratory were first investigated on a large, national scale in the United States. This study revisits these goals, using data from a 2022 national survey of chemistry faculty members in the United States (n = 521) to investigate current…

The Investigative Science Learning Environment (ISLE) approach to learning and teaching holds as one of its core tenets that students should learn physics by engaging in the same processes through which physicists develop new knowledge. One key skill necessary for this is hypothetico-deductive reasoning. In this study, we explored how the…

Coagulation is an important process in the context of water purification; and the seed protein of the moringa tree ("Moringa oleifera") is a remarkably effective coagulant. The laboratory course described here is designed to provide high-school students with a stepwise, hands-on experience in investigating the protein-rich coagulant…

The aim of the study is to examine the relationship between the learning styles of classroom students in the force and energy unit and their scientific process skills. In the study, pre-test and post-test weak experimental design without a control group was used. The research was carried out in 2 different secondary schools in the central district…

This paper aims to review and assess the strategies available in literature to improve the practices of science process skills (SPS) among students. SPS encompasses the mental and physical activities of students in collecting and organizing information and then using the information to make predictions, explain phenomena, solve problems,…

The concept of co-amorphous systems is introduced in an integrated laboratory experiment, designed for advanced chemistry students, using solvent-free, environmentally friendly mechanochemistry. The dual-drug naproxen-cimetidine co-amorphous system (NPX-CIM) is investigated as an example of the emergent field of medicinal mechanochemistry.…

Chemistry in water is an emerging field that fulfills the fifth principle of green chemistry: replacing toxic organic solvents with their benign counterparts. Although some pharmaceutical industries have developed and adopted chemistry in water, its implementation in teaching laboratories is still limited. Therefore, we have designed an experiment…
