This study was designed to investigate the relationship between the metacognitive awareness of university students and their solutions to the similar mathematical problem types. Participants were 97 freshmen from department of mathematics at a state university in Turkey. Two different scales were used for data collection: "Metacognitive…

This article presents the results of a trend study investigating what students associate with the term radiation and what ideas they have about this topic. The first part of the interview study was conducted in June 2010 and its results were reported in a previously published article (Neumann & Hopf, 2012). Two years later (June 2012, 15…

This study attempted to explore 15 Korean elementary pre-service teachers' views of inquiry teaching. During a science teaching methods course, pre-service teachers implemented a peer teaching lesson, had a group discussion to reflect on five teacher educators' comments on their first peer teaching practice, and revised and re-taught the…

The effect of different textual versions (macroscopic (control), submicroscopic, and guided imagery) of the explanation of a chemical phenomenon on students' submicroscopic explanation of a related phenomenon was examined. The sample included 152 pre-service science teachers. The three textual versions of the explanation were distributed randomly…

The purpose of this study was to investigate the role of e-learning, as a pedagogical tool, for changing initial conceptions when learning about physics by using the learning management System of the Moodle platform. Our study provides an empirical exploration of the pedagogical use of Moodle Learning Management System (LMS) in order to…

In this paper, we examine selected literature on classroom-based research to understand how students and teachers (re)negotiate the language of interaction in a mathematics classroom when the official medium of instruction is different from the students' dominant language. We identify the tensions and dilemmas associated with the implementation of…

In recent decades, the literature paid attention to students' conceptions of the nature of disciplines. This study aimed to investigate how students' cohesive and fragment conceptions of physics changed with a major change in senior high school physics syllabus. We obtained measures of conceptions of physics by utilizing a 20-item questionnaire…

This study explored primarily the elementary teachers' motivations and expectations for engagement in a science professional development. Participants (N=20) were elementary teachers in two public schools from the United States and were enrolled in a yearlong science professional development; however, due to various factors teachers did not…

Textbooks are a major tool in the teaching and learning process. This paper presents the results of an analysis of the Finnish and Thai 6th grade science textbooks: electric circuit lesson. Textual and pictorial information from the textbooks were analyzed under four main categories: 1) introduction of the concepts, 2) type of knowledge, 3)…

Solution set of any inequality or compound inequality, which has one-variable, lies in the real line which is one dimensional. So a difficulty appears when computer assisted graphical representation is intended to use for teaching these topics. Sketching a one-dimensional graph by using computer software is not a straightforward work. In this…

This study investigated the influence of metacognitive guidance on pre-service science teachers' scientific knowledge, science process skills, and views about the nature of science. The sample included 48 pre-service science teachers taking a first-year chemistry laboratory course in a public university in Turkey. During the 11-week course, the…

The aim of this study was to identify the type of conceptual change (assimilation or accommodation) that can be induced by a refutational text. Individual interviews were carried out with a stratified sample of eighty-seven grade 9 students. Forty-four percent of them were found to have a misconception about the concept of ecological role--they…

The development of the concept of matter was explored in children aged 3-13. Eighty four children were asked to classify four sets of objects and matter and to explain their classifications during interviews. Younger children tended to classify using a mixture of extensive properties (properties of objects) and intensive properties (properties of…

Mental models of metallic bonding held by learners from three academic levels, secondary school (year 12), undergraduate, and postgraduate, were probed using semistructured interviews including the use of Interviews-About-Events focus cards depicting metallic properties and cards containing depictions of models from curriculum material. The…

This work is grounded in a constructivistic conception of the learning of science, more particularly on the model known as teaching-learning as oriented research. In accordance with this theoretical basis we have developed an empirical research project to investigate the teaching of electrostatics in high schools. The designs developed have…
