This study provides insights into the use of metaphors in protein synthesis descriptions in upper secondary chemistry and biology textbooks. Data were collected from seven Swedish textbooks and analyzed with the Metaphor Identification Protocol and categorized within the framework of Conceptual Metaphor Theory. The results reveal two main parallel…

Intellectual demands of learning outcomes in the intended curriculum have always been a concern across the field of science education. In particular, the representation of those learning outcomes stipulated by the intended curriculum in science textbooks has become a big issue for both science curriculum studies and science teaching practice. To…

This study aims to evaluate students' ability to process the context information embedded in chemistry problems. To achieve this goal, a diagnostic measurement instrument was developed, comprising 28 short-answer items embedded in seven context-based chemistry tasks. Four hundred and ninety-three ninth-graders took part in the testing in Jiangsu,…

The significance of the role of students' interpretation and creation of multiple forms of representation in science learning has long been established and advocated, but there is a paucity of research into the extent to which this emphasis in science education is reflected in high stakes final year high school science examinations. This study…

Chemical thinking has been widely recognized as a core competence that students develop in chemistry education. This study examined the distribution and representation forms of chemical thinking in the five Chinese high school chemistry textbooks aligned with the new national standards in Mainland China. We employed the framework of essential…

Students commonly find specialist scientific language problematic. This study investigated developments in chemical language usage by six "non-traditional" students over the course of 1 to 4 years. The students participated in semi-structured interviews and were asked to explain specific chemical scenarios. Interviews were transcribed…

Declining enrolments in senior secondary science have heightened concerns for meeting the demands for more STEM-qualified workers and a scientifically literate society. Students' attitudes to science are formed during schooling, particularly in adolescence when they are exposed to a variety of science topics. Students' perceptions of their ability…

In this paper, chemistry teachers' reactions/behavior or actions following students' undesired, unexpected or incorrect responses/answers to the posed teacher oral questions are reported. This study which was carried out in Tanzania in Iringa Municipality involved three chemistry teachers teaching in three different secondary schools. Actual…

Science teachers' pedagogical content knowledge (PCK) has been researched in many studies, yet little empirical evidence has been found to determine how this knowledge actually informs teachers' actions in the classroom. To complement previous quantitative studies, there is a need for more qualitative studies to investigate the relationship…

The development of science education in many countries is varied and diverse. However, one common goal of science education in the different contexts is the focus on scientific literacy. To promote scientific literacy, the Nature of Science (NoS) is one of the vital components for raising scientifically literate citizens. In view of this, the…

Learning objectives outline the knowledge and skills to be taught in a subject, thus signaling what is worth learning and what type of thinking is valued. The aim of this syllabus analysis is to determine the cognitive demand of learning objectives in the recently reformed Queensland physics, chemistry and biology syllabus and to analyse whether…

One of the core practices of science teachers is the construction of science teaching explanations. These explanations serve to clarify concepts, procedures, facts, ideas, or types of problems, and are aimed at promoting student understanding. The low performance of Chilean science teachers on explanations has led us to incorporate instances in…

The interrelationship between mathematics and science education has frequently been emphasized, and common goals and approaches have often been adopted between disciplines. Improving students' problem-solving skills in mathematics and science education has always been given special attention; however, the problem-posing approach which plays a key…

Educational reforms in Qatar have seen the implementation of inquiry-based learning and other student-centred pedagogies. However, there have been few efforts to investigate how these adopted western pedagogies are aligned with the high context culture of Qatar. The study presented in this article highlights the implementation of a student-centred…

Science and science education are recognised internationally as essential for ensuring a sustainable and prosperous future. At the same time, significant equity issues are apparent in science education. This study used enrolment and academic result data, routinely collected from government schools in Victoria, Australia, to examine the impact of…
