The purpose of this study was to investigate the development of pre-service chemistry teachers' (PCTs') argumentation skills in a laboratory course throughout a semester. A case study design was utilised. A total of six PCTs participated in the study. To investigate the development of PCTs' argumentation skills, the laboratory reports that were in…

Science teachers mediate social and academic language in science classrooms through teacher talk and classroom discourse. In multilingual classrooms, ways home and international languages are deployed can affect conceptual learning of science. This study investigates, through Bakhtin's dialogic perspective, multilingual language practices and…

Research points to the important role achievement emotions play in academic performance and career choices, yet few studies have examined achievement emotions in non-Western contexts. The current study extends this research base by examining students' achievement emotions among 103 eleventh-grade high school chemistry students in China. Using…

The aim of this study is to provide an understanding of context-based inquiry teaching within a humanistic perspective on science education by studying pre-service teachers' beliefs about inquiry and their implementations of inquiry in their context-based teaching sequences. Therefore, five pre-service teachers enrolled in a university…

The purpose of this study is to examine the salient characteristics of the 'Question-Answer Process' (QAP) in senior high school chemistry class between pre- and in-service teachers. We first developed the 'Instrument of Question-Answer Process' (IQAP), and then, applied it to compare salient characteristics of QAP between pre- and in-service…

We developed a computerised simulation that utilises embodied modelling by letting students play the role of particles in a liquid. We compared the learning of two eight-grade classrooms that used the embodied modelling simulation during a weeklong learning module on phase change, with a comparison group that used an ordinary simulation with no…

Researchers have shown a growing interest in science teachers' professional knowledge in recent decades. The article focuses on how chemistry teachers impart chemical bonding, one of the most important topics covered in upper secondary school chemistry courses. Chemical bonding is primarily taught using models, which are key for understanding…

This study describes an investigation of a research apprenticeship program that we developed for diverse high-school students often underrepresented in similar programs and in science, technology, engineering, and math (STEM) professions. Through the apprenticeship program, students spent 2 weeks in the summer engaged in biofuels-related research…

Considerable attention has been devoted to factors affecting the persistence of women and historically underrepresented ethnic groups in their science education trajectories. The literature has focused more on structural factors that affect longitudinal outcomes rather than classroom experiences. This exploratory survey study described…

This paper reports on a case study of an immersive and integrated multi-instructional approach (namely computer-based model introduction and connection with content; facilitation of individual student exploration guided by exploratory worksheet; use of associated differentiated labs and use of model-based assessments) in the implementation of…

Devised is a test involving chemical examples to establish to what extent college chemistry students recognized and assessed the explanatory content of statements presented in the form of justifications. Several results are discussed. Several test items are included. (Author/YP)

Identifies and describes the problems students have with the concept of neutralization. Analysis of over 7,500 students' answers to test questions over neutralization showed that many students understand the concept in its original meaning. Students assumed that in any neutralization reaction a neutral solution is formed, even if a weak acid or…

In this study, we investigated the perceived professional needs of Korean science teachers majoring in chemical education, and examined their preferences for online and on-site inservice teacher training programmes. The results were also compared with those of preservice teachers. Participants were 120 secondary school teachers and 67 preservice…
