This research aimed to understand what physics and chemistry pre-service teachers learn within pedagogical content knowledge in a lesson study with the topic speed of sound, 8th grade. Participants were three pre-service teachers. This was a qualitative and interpretative study. Data were collected from participant observation, individual…

The impacts of a technology-integrated formative assessment technique on students' conceptual and procedural knowledge in studying chemical equilibrium are studied in this study. To attain the purpose, a quasi-experimental pretest-posttest strategy nested with a qualitative study method was adopted. The study has three groups: two experimental and…

Though there are a multiplicity of approaches that have been used to promote Nature of Science (NOS) among school students, an approach based on exploration of a scientific discovery indigenous to the sample population, of contemporary interest, and based on a topic outside the school science syllabus seems to be lacking in the literature. This…

In this article, we focus on a set of remote activities regarding simulated juries, judges' evaluations, communication of verdicts, and a post-discussion conversation. These activities aimed to promote learning of the preservice teachers about the differences between remote and in-person teaching in a chemistry teaching methods course. The set of…

This article presents a study conducted at Georgia Gwinnett College (GGC) to explore the use of ChatGPT, a large language model, for fostering critical thinking skills in higher education. The study implemented a ChatGPT-based activity in introductory chemistry courses, where students engaged with ChatGPT in three stages: account setup and…

In the past decade, scientific process skills and scientific attitudes are widely regarded as essential factors influencing students' achievement and their future career choices. Unfortunately, previous literature found that students' scientific skills and attitudes tend to be unsatisfactory. Thus, cultivating students' skills and attitudes is…

Redox reaction is an important concept in chemistry, and a well-organized knowledge structure of redox reaction is beneficial for concept learning. This study investigated the knowledge structure regarding redox reaction from 459 Grade 10 students. The pool of 15 redox reaction concepts was developed by content analysis, questionnaire survey, and…

A primary motivation for this study was to compare student perceptions and performance within a virtual learning environment to the traditional in-person learning experience for the General Chemistry II course taught during a 5-week summer session at Xavier University of Louisiana, a minority serving institution. The authors present quantitative…

General chemistry is a mandatory course for those in pursuit of careers in various allied health and science, technology, engineering, and mathematics (STEM) fields. However, many students find chemistry difficult. For English language learners (ELLs), the situation is especially demanding, as these students are required to learn the specialized…

This study analyzed cognitive representations of knowledge from the chemistry of matter unit in a ninth-grade science textbook--the only authorized textbook in Saudi Arabia. It examined textual and visual information from two lessons in order to identify the textbook's introduction of concepts, linguistic context, integration of concepts, and the…

The transition to a remote teaching and learning environment was quick and painful at times, and yet it was a learning experience for everyone. The chemists at Centre College utilized new (to them) technology to reimagine the typical face-to-face interactions with students and colleagues. From Slack to Pear Deck to Zoom classrooms, the faculty and…

The social distancing measures introduced to prevent the spread of COVID-19 have led to the rapid redesign of chemistry instruction in higher education from face-to-face to online delivery. The design, implementation, and evaluation of a redeveloped undergraduate level course on catalysis which was delivered to 188 students (including 22 natural…

Creativity is an important skill that will increasingly play a role in the future professional sphere, not only in arts and crafts professions but also in science, technology, engineering and mathematics (STEM) professions. It is precisely in this field that new methods and products have to be constantly developed. Therefore, the promotion of high…

The purpose of this quasi-experimental study is to evaluate the overall effect of practical work on students' academic attainment in science. Participants were selected from tenth grade students (chemistry and biology) and eleventh grade students (chemistry), then divided into groups. The control groups were taught using traditional methods of…

Science and science education are recognised internationally as essential for ensuring a sustainable and prosperous future. At the same time, significant equity issues are apparent in science education. This study used enrolment and academic result data, routinely collected from government schools in Victoria, Australia, to examine the impact of…
