The purpose of this study was to investigate how a mixed-method case study affects pre-service science teachers' awareness of hexavalent chromium pollution and content knowledge about the properties of chromium's different oxidation states. The study was conducted in Turkey with 55 sophomores during the fall semester of 2013-2014. The…

Data-driven inquiry (DDI) is the process by which teachers design and implement classroom assessments and use student results to inform/adjust teaching. Although much has been written about DDI, few details exist about how teachers conduct this process on a day-to-day basis in any specific subject area, let alone chemistry. Nineteen high school…

This is an interpretive case study to examine the teaching of an experienced science faculty who had a strong interest in teaching undergraduate and graduate science courses and nature of science specifically. It was interested in how he transformed knowledge from his experience as a scientist and his ideas about nature of science into forms…

Previous research has revealed that students may hold several misconceptions regarding fundamental topics of chemistry. With the idea that teachers play a critical role in diagnosis and remediation of students' misconceptions, a "course" for preservice chemistry teachers was designed. The purpose of this study was to describe the views and…

Five high-school chemistry teachers were asked to enact a lesson in which they posed a problem for which students were likely to generate solutions based on reasoning that was not aligned with accepted principles of chemistry. Four teachers selected a problem related to the stoichiometry of a reaction; the fifth chose a problem associated with…

This article summarises the author's experiences in running a module "Computers for Chemistry" entirely online for the past four years. The module, previously taught in a face-to-face environment, was reconfigured for teaching in an online environment. The rationale for moving online along with the design, implementation and evaluation of the…

The years between 2005 and 2014 have been declared as a worldwide Decade of Education for Sustainable Development (DESD) by the United Nations. DESD's intended purpose is to promote and more thoroughly focus education as a crucial tool preparing young people to be responsible future citizens, so that our future generations can shape society in a…

The purpose of this article is to describe a best practice: an approach to teaching chemistry that our quantitative research has shown to produce large differences between experimental and control groups in terms of achievement, pro-environmental attitudes, values, and motivation. Our interest in teaching chemistry by focusing on sustainable…

While lecture demonstrations have been conducted in chemistry classrooms for hundreds of years, little research exists to document the frequency with which such demonstrations are employed or their effect on learners' motivation and performance. A mixed-methods research study was performed, using quantitative and qualitative survey data, along…

This study evaluates experienced teachers' views of chemistry teaching and learning and educational reform in Jordan. The main focus is an investigation of applied teaching practices in chemistry education, including educators' perception of the intentions and effects of ongoing educational reforms. The study is based on semi-structured interviews…

The aim of this study was to explore pre-service primary teachers' understandings of the effect of temperature and pressure on the solid-liquid phase transition of water. In the study a survey approach was used, and the sample consisted of one-hundred and three, third year pre-service primary science teachers. As a tool for data collection, a test…

We have investigated the effects of a teaching intervention based on evidence from educational theories and research data, on students' ideas in chemical kinetics. A quasi-experimental design was used to compare the outcomes for the intervention. The subjects of the study were 83 university first-year students, who were in two different classes in…

Inquiry-based instruction requires a deep, conceptual understanding of the process of science combined with a sophisticated knowledge of teaching and learning. This study examines the changes in classroom instructional practices and corresponding changes to knowledge and beliefs about inquiry instruction for eight high school chemistry teachers.…

The nature and behavior of gas particles are essential concepts in teaching and learning of school chemistry. However, findings about students' understanding of gas particles--their composition, structure, and interactions involving movement and distribution--revealed that the difficulties students encounter in understanding gas particles vary…

This paper reports part of the results of research on chemical problem solving behavior of pre-service teachers in Plateau and Northeastern states of Nigeria. Specifically, it examines and describes the methods used by 204 pre-service teachers in solving quantitative problems from four topics in chemistry. Namely, gas laws; electrolysis;…
