A classroom based Problem Based Learning (PBL) activity was adapted to run as a remote activity during the COVID-19 pandemic using an approach described as virtual Problem Based Learning (vPBL). vPBL is based on (i) identification of a suitable learning platform that supports collaborative working in a way that mimics the classroom based activity…

In recent years there has been an increased emphasis on recruiting and retaining STEM students in order for the United States to retain its position as a leader in STEM fields (President's Council of Advisors on Science and Technology, (2012), Report to the president, engage to excel: Producing one million additional college graduates with degrees…

During the SARS-2-COVID pandemic our institution sought to continue the teaching and learning of experimental laboratories by designing, assembling, and delivering a microscale chemistry kit to the students' homes. Thanks to this approach students were able to perform [approximately]25 experiments during each one of the Fall 2020 and Spring 2021…

Lesson study (LS) is an effective means of improving teachers' facility with teaching design. This research designs a case study of online to offline (O2O) LS and explores the social interaction and behaviour patterns in the process of the LS. The participants included 29 chemistry teachers from 10 secondary schools and two educational technology…

The purpose of this study is to examine pre-service chemistry teachers' orientations towards chemistry teaching during chemistry teaching method courses. This study was conducted with ten pre-service chemistry teachers for 28 weeks. The Draw-A-Science-Teacher-Test Checklist (DASTT-C), card-sorting activity, interviews, observations, and reflection…

A significant number of instructors, researchers and students have claimed that chemistry is a challenging subject to teach and learn at all education levels. Its main learning difficulties are in line with certain sights of its phenomena that are abstract, and some chemistry teachers do not specify what to be learned and assessed in chemistry…

The purpose of this study was to develop pre-service chemistry teachers' pedagogical content knowledge (PCK) regarding atoms and the periodic table via mentoring. Two pre-service chemistry teachers with different levels of academic achievement participated in the study. The development of the participants' PCK was investigated in terms of the…

This paper reports on how a group of students think when trying to solve a set of thermodynamic revision exercises in the context of collaborative small group conversation at the undergraduate level. The revision exercises involved exploring the relationship between enthalpy and temperature, entropy and temperature, and entropy of a gas under…

Building reasonable scientific arguments is a fundamental skill students need to participate in scientific discussions. In organic chemistry, students' argumentation and reasoning skills on reaction mechanisms are described as indicators of success. However, students often experience challenges with how to structure their arguments, use scientific…

Student understanding of chemical equilibrium in aqueous solutions (CEAS) plays a vital role in their upper secondary school chemistry learning and everyday life. Diagnosis of students' alternative conceptions (ACs) of the CEAS will provide teachers with valuable information to make instructional decisions on student learning. This study aims to…

Computational and atmospheric chemistry are two important branches of contemporary chemistry. With the present topical nature of climate change and global warming, it is more crucial than ever that students are aware of and exposed to atmospheric chemistry, with an emphasis on how modeling may aid in understanding how atmospherically relevant…

While group work in undergraduate science education tends to have overall benefit, less is known about the specific peer-peer dynamics that optimize learning during group interaction. The current study used peer ratings and self-reported data from 436 students enrolled in team-based undergraduate science courses (biology or chemistry) to determine…

The aim of this study is to analyse the importance of the number of raters and compare the results obtained by techniques based on Classical Test Theory (CTT) and Generalizability (G) Theory. The Kappa and Krippendorff alpha techniques based on CTT were used to determine the inter-rater reliability. In this descriptive research data consists of…

This study aimed to develop alternative laboratory experiments (ALEs) in Chemistry 8 and evaluate the perceived improvement of the students' basic science process skills after utilizing the material. This employed a mixed method of research. Initially, a self-assessment survey questionnaire was used to determine the basic science process skills of…

Current studies on group work illustrate the importance of student collaboration for enhancing conceptual understanding and participation in science. Research also documents the roles students adopt within group work, with some studies illustrating the underlying power relations. This study sought to expand on prior research literature to…
