A curriculum is generally regarded as an instructional plan that describes what, why and how students should learn. In this comparative study, we analysed the Czech and Slovak intended curricula of science subjects (physics, chemistry, biology, geography, and geology) and mathematics by comparing their national curriculum documents in terms of…

Understanding the nature of science (NOS) is an important goal of science education, and textbooks are a key factor in shaping students' conceptions of NOS. In this study, we analysed NOS represented in middle school chemistry textbooks in the Chinese mainland. The selected materials were three most commonly adopted textbook series, which were…

The impact of self-regulated learning (SRL) on students' performance in various subjects has been extensively studied. However, there has been limited research on how task-specific SRL skills and self-reported SRL skills affect students' learning outcomes in chemistry classes at senior secondary schools. To address this gap, we examined the…

Students' interest is considered an important learning outcome, but it is also a relevant predictor for student learning, and future vocational choices. According to numerous studies, however, students' interest in STEM fields usually declines during the course of secondary education. From the perspective of science education, it is therefore…

In this study, we present a new instrument, the Participation and Engagement Scale (PES), for the evaluation of the students' involvement in STEM-oriented activities. The instrument was administered to about 1000 secondary school students who participated in the activities of the Italian "Piano Nazionale Lauree Scientifiche" in Biology,…

Professional development courses help teachers integrate new content knowledge into the high-school curriculum. Designing practical online courses for this purpose is challenging, particularly in emerging fields such as nanotechnology. In this study, we evaluated such a course in three complementary dimensions: (1) knowledge, (2) the complexity of…

Chemistry-related courses cover a wide range of disciplines focusing on the application of Chemistry. The purpose of this study was to determine factors affecting student's future intention to enroll in chemistry-related courses in the Philippines. A total of 953 senior high school students from the Philippines answered an online questionnaire…

The study of questions has occupied a prominent role in the research into classroom discourse. For science teaching, questions are fundamental since they can connect students with the patterns of scientific thinking. In this article, we developed analytical tools to investigate the epistemic dimension of questions in chemistry teaching. We draw…

The study aims to investigate students' conceptualisation of the quantum numbers concept through their verbal descriptions and pictorial representations of the corresponding atomic structures. The study was conducted with the participation of 192 12th-grade students from six secondary schools in Northern Greece, via a paper-and-pencil test,…

This study aims at investigating students' awareness of green chemistry principles (GCPs) which are infused in two context-based projects that are related to socio-scientific issues, namely climate change and materials' recycling. At first, content analysis of the projects' activities showed the infusion of four GCPs. Subsequently, the students'…

This study took 'context' as a focal point in the context-based approach and its investigation was anchored on an analytical framework, which is composed of three dimensions of context: origins, intentions, and occasions. Content analysis was employed as the research methodology with 878 contexts identified from 96 copies of awarded chemistry…

In this study, we compared the effects of cooperative flipped learning (CFL) on science achievement and learning motivation with those of simple flipped learning (SFL) and traditional lecture (TL) using a mixed-methods design. Three classes containing a total of 65 first-year high school students in South Korea were randomly assigned to the CFL,…

Logical connectives are grammatical linkers that appear as essential components in the production of logical argumentation of inquiry and critical thinking in school science activities. However, these cohesive terms represent a language barrier for science student learning. Therefore, students' lack in their understanding of academic connectives…

Context-based learning has become increasingly influential in science education over the last 40 years. However, it is still unclear which types of contexts foster students' interests and learning achievements and are appropriate for science classes. While contexts are usually selected by teachers or curriculum developers, this study focusses on…

We studied the emotions experienced by students during the last two years of compulsory secondary education (15 and 16 years old) when learning physics and chemistry. The objective of this piece of research was to establish different relationship between emotions felt by students and variables like the didactic methodology or the kind of science…
