This paper illustrates the role of metalanguage in an explicit literacy instruction to talk about the forms and functions of scientific genres, particularly the genre of explanation. In the context of science, metalanguage refers to the technical terms for talking "about" scientific language using words like law, hypothesis, and…

Teachers lack effective curriculum-based instruments to assess their students' scientific competence that would provide information for modifying their inquiry instruction. The main purpose of this study was to develop and validate a Curriculum-Based Scientific Competence (CBSC) test to assess students' scientific competence in a 1-semester Grade…

Surveying is a common methodology in science education research, including cross-national and cross-cultural comparisons. The literature surrounding students' attitudes toward science, in particular, illustrates the prevalence of efforts to translate instruments with the eventual goal of comparing groups. This paper utilizes survey data from a…

Scientific models and modeling play an important role in science, and students' understanding of scientific models is essential for their understanding of scientific concepts. The measurement instrument of "Students' Understanding of Models in Science" (SUMS), developed by Treagust, Chittleborough & Mamiala ("International…

This study developed, validated, and utilized the Technology Integrated Classroom Inventory (TICI) to examine technology-integrated science learning environments as perceived by secondary school students and teachers. Using technology-oriented classroom climate instruments and considering the science classroom's characteristics, TICI was…

A model of reading comprehension of geometric proofs (RCGP) has recently been proposed by the authors. This article further investigates students' development of such comprehension based on this model, looking at the relationship between students' reading comprehension and their prior knowledge and logical reasoning. The results show that (1)…

Three issues about students' reasoning, proving and understanding proof in number patterns are investigated in this paper. The first is to elaborate the features of junior high students' reasoning on linear and quadratic number patterns. The second is to study the relationships between 9th graders' justification of mathematical statements about…
