The implementation of context-based chemistry programs has been started before 40 years ago since 1980s in an attempt to make the learning of chemistry more meaningful for students. Consequent to its lengthy, there has been a steady increase in the number of interventional context-based (ICB) approach chemistry studies investigating the effect of…

In chemistry, reasoning about the underlying mechanisms of observed phenomena lies at the core of scientific practices. The process of uncovering, analyzing, and interpreting mechanisms for explanations and predictions requires a specific kind of reasoning: mechanistic reasoning. Several frameworks have already been developed that capture the…

Concept mapping remains widely used in education. However, little is known about how self-constructed concept maps and peer feedback can improve student learning outcomes in chemistry. We investigated the effects of peer feedback on concept mapping and how it improves students' learning performance in a large second-semester, introductory…

Use of modeling as a learning strategy in introductory science courses could serve to support the persistence of all students, including those who identify with a traditionally underrepresented ethnic minority (URM). If students find inherent value in working on modeling-type problems then this authentic practice would aid in transforming personal…

The most obvious feature of expertise in chemistry is content knowledge, which defines the primary objectives of instruction. Research in chemistry education, and STEM education more broadly, has also devoted attention to students' developing scientific practices of reasoning, investigation, and learning. In this study, we set out to investigate…

In group activities, students work collaboratively to accomplish specific objectives. Students have to engage and interact with each other in order to complete collaborative assignments. One way that students stay engaged is through asking questions. In the research reported here, we looked at peer-to-peer questions in the context of a…

Explaining natural phenomena by determining causal relationships is conducive to understanding scientific concepts. In science education, numerous studies examine students' causal reasoning. Given the importance of core ideas for students' understanding of how and why a phenomenon occurs, the study focused on the relationship between students'…

This work details the ramifications of online learning using a novel, personalized learning system regarding high-school students' experiences, attitudes, self-efficacy, and achievements during the 2020-2021 school year. Although research has explored the implications of remote and online learning on education worldwide, little attention was…

Background: Science educators around the world have recognised that difference in performance exists between male and female students in chemistry and there have been several efforts and interventions through research and workshops to bridge this gap. Purpose: Owing to the current growth of the effects of the use of computer simulations on…

Background: In the previous decades many research papers and educational documents have emphasized the importance of the application of history of science in the science education of students. Consequently, chemistry teachers are expected to be familiar with the historical development of science and capable of incorporating historical contents in…

Recent studies in applied linguistics research have focused on how teachers draw on 'outside' knowledge relating to students' everyday life for the purpose of teaching subject matter content. This study focuses on such practices in the context of English-medium instruction (EMI) higher education in an online undergraduate chemistry module.…

Being able to move between different representations levels (macroscopic, submicroscopic, and symbolic) is important to understand a chemical phenomenon meaningfully. The current study investigated how pre-service science teachers moved from symbolic representation to sub-microscopic representation. A total of 205 pre-service science teachers,…

This study investigated Chemistry students' performance and retention (knowledge and understanding, knowledge and application, perception and attitude) in Organic Chemistry in three Senior High Schools (SHSs) within Tamale Metropolis in Ghana. Collaborative learning models were employed as intervention strategies. Quasi-experimental design was…

The Peer Assisted Learning (PAL) program at Sacramento State was established in 2012 with one section supporting introductory chemistry. The program now serves 17 courses with high rates of students who receive a D or an F or withdraw (DFW) from the course in biology, chemistry, mathematics, physics, and statistics; the program enrolls…
