Reading comprehension is an essential skill for learning in general and in science classes. Problems with reading comprehension might hinder students' participation in learning science. Text in science includes specific language features that distinguishes it from narrative text, so should reading instruction be part of teaching science? The…

The history of science (HOS) has played an important role in science curricula for teaching about science. However, historical information in science textbooks is often de-contextualized, coupled with limited class time and teaching barriers, and thus fails to help students understand the dynamic process of scientific development. This research…

The aim of this study is to investigate the effectiveness of the common knowledge construction model (CKCM)-based instruction on academic achievement and 7th grade students' views about the nature of science (NOS) presented in electrical energy unit at schools of different socio-economic levels. In accordance with this purpose, three secondary…

This study investigates the effect of design-based science (DBS) instruction on students' learning of electrical energy and students' metacognitive strategy use in science. Two classes of seventh-grade students participated in the study. DBS instruction was used in the treatment group, while the comparison group was taught the unit with…

The purpose of this study was to investigate the student and teacher-level predictors of Turkish middle school students' engagement in science classes. Students' engagement was examined in terms of agentic, behavioral, cognitive, and emotional engagement. The participants of the study were 134 Turkish science teachers and their 3394 grade 7…

This study aimed to investigate the role of students' classroom learning environment perceptions and teacher effectiveness in 7th grade students' self-regulation in science classes. Students' self-regulation was examined in terms of self-efficacy, achievement goals, and metacognitive strategy use which constitute important components of…

Reported are the results of a multiyear study in which reading comprehension and writing were integrated within an in-depth science instructional model (Science IDEAS) in daily 1.5 to 2 h daily lessons on a schoolwide basis in grades 3-4-5. Multilevel (HLM7) achievement findings showed the experimental intervention resulted in significant and…

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…

The Framework for Science Education and the Next Generation Science Standards in the USA emphasize learning progressions (LPs) that support conceptual coherence and the gradual building of knowledge over time. In the domain of genetics there are two independently developed alternative LPs. In essence, the difference between the two progressions…

The aim of this study was to develop and validate Science Homework Scale (SHS) which assesses middle-school (grades 6-8) students' perceptions of teachers' homework practices and homework self-regulation in science. Students' perceptions of teachers' homework practices included homework quality and feedback on homework while students' homework…

This study aimed at identifying the levels of scientific reasoning of upper primary stage (grades 4-7) science teachers based on their use of a problem-solving strategy. The study sample (N = 138; 32 % male and 68 % female) was randomly selected using stratified sampling from an original population of 437 upper primary school teachers. The…

In this paper, we analyze the science activities offered at 7th grade in the Turkish science and technology curriculum along with addressing the curriculum's original intent. We refer to several science education researchers' ideas, including Chinn & Malhotra's (Science Education, 86:175--218, 2002) theoretical framework and Edelson's (1998)…
