The purpose of the study was to investigate the relationship between high school students' understandings of aspects about nature of science (NOS) and their argumentation skills, particularly whether informed conceptions of NOS contribute to better argumentation skills. Participants, a total of 125 Grade 10 students, responded to an open-ended…

Emotions play an essential role in educational processes. Previous research has mainly dealt with achievement emotions which are experienced in specific situations such as exams or learning situations in mathematics (e.g. enjoyment or anxiety). Some achievement emotions are rather experienced in social contexts in mathematics and are closely…

This study integrated environmental issues as the initial problem to explore the process of problem-solving of high school students and proposes the concept of environmental problem-solving (EPS) to probe the interaction between high school students' scientific performance and EPS strategies. There were 139 high school students in Taiwan who…

Studies measuring teachers' beliefs quantitatively by using self-report Likert scale instruments often face methodological difficulties. Such difficulties might be due to the fact that those instruments often provide less or no contexts. Whereas, several studies have shown that contexts at school, particularly contexts related to students'…

This study is a detailed look at the level of understanding of fundamental ideas about blackbody radiation (BBR) among physics teachers. The aim is to explore associations and ideas that teachers have regarding blackbody radiation: a concept used routinely in physics and chemistry, which is necessary to understand fundamentals of quantum physics.…

This study explored the structural relationships among secondary school students' conceptions, self-regulation, and strategies of learning science in mainland China. Three questionnaires, namely conceptions of learning science (COLS), self-regulation of learning science (SROLS), and strategies of learning science (SLS) were developed for…

The constructivist learning approach is suggested as a means for facilitating students' learning of science and increasing their participation in this learning. Several studies have shown the contribution of this approach to the different aspects of students' learning of science, though little research has examined the contribution of this…

The boom in Internet and communication technology has accelerated change in information delivery channels from paper to networked, digital displaying devices. Reading electronically has altered the cognitive and metacognitive processes readers use to approach science texts. Assessing reading in a digitized environment also opens up opportunities…

The purpose of this study was to probe the differences of perceived professional teaching competence between elementary school math/science teachers in Taiwan who are majored in math/science and those who are not. A researcher-developed Math/Science Teachers' Professional Development Questionnaire was used in a nationwide survey, using a two-stage…

Science, technology, engineering, and mathematics (STEM) in early childhood education is an area currently given little attention in the literature, which is unfortunate since young children are natural scientists and engineers. Here, we outline our mixed-methods design-based research investigation of a pre-kindergarten (Pre-K) classroom where two…

The understanding of measurement is related to the understanding of the nature of science--one of the main goals of current international science teaching at all levels of education. This case study explores how a first-year university physics course deals with measurement uncertainties in the light of an epistemological analysis of measurement.…

A 30-item questionnaire was designed to determine Omani science teachers' attitudes toward teaching science and whether or not these attitudes differ according to gender and teaching experiences of teachers. The questionnaire items were divided into 3 domains: classroom preparation, managing hands-on science, and development appropriateness. The…

Chemical representations serve as a communication tool not only in exchanges between scientists but also in chemistry lessons. The goals of the present study were to measure the extent of student teachers' knowledge about chemical representations, focusing on chemical formulae and structures in particular, and to explore which factors related to…

The purposes of this study are to investigate Turkish pre-service middle school mathematics teachers' ability in conducting valid proofs for statements regarding numbers and algebra in terms of their year of enrollment in a teacher education program, to determine the proof methods used in their valid proofs, and to examine the reasons for their…

For science teachers using the discourse of socioscientific issues (SSI), it is important to make a decision as to whether when and how to disclose their own positions. The existing limited literature shows that science teachers prefer one of four roles during SSI discourse: sticker to facts, imposer, democracy advocator, and committed…
