Adopting an explicit and reflective approach to the teaching of the history and philosophy of science is useful in promoting high school students' understanding of the nature of science. Whereas the history of science is usually signposted clearly in the school science curriculum, the philosophy of science is considered to be embedded in and…

This study aims to specify the effect of inquiry-based collaborative learning and inquiry-based online collaborative learning methods on students' success and permanent learning. In this quantitative study, a pre-test post-test non-equalized control group model of quasi-experimental design has been used. The study's sample comprises 64 students,…

Regular science practices in preschool are crucial for children's learning in science. Yet, preschool teachers may only offer science learning opportunities if they "are" and "feel" sufficiently qualified to teach early science. The present study investigates the relation between teachers' qualifications, their self-efficacy…

This study aims to determine the topic-specific nature of two experienced chemistry teachers' pedagogical content knowledge (PCK) in the topics of interactions between chemical species and states of matter. The teachers' PCK on these topics was investigated in terms of the following components: orientations toward science teaching (OST), knowledge…

Planetariums have been used for a long time in astronomy education. Due to some disadvantages of permanent planetariums, it is seen that portable planetariums have become popular in recent years. Portable planetariums, due to their easy set up in anywhere, offer opportunities for those students studying in the regions where there are not…

We systematically compared two coding approaches to generate training datasets for machine learning (ML): (1) a holistic approach based on learning progression levels; and (2) a dichotomous, analytic approach of multiple concepts in student reasoning, deconstructed from holistic rubrics. We evaluated four constructed response assessment items for…

Many educational researchers and teachers have agreed that language can be fostered in the context of science teaching. However, the effect of language fostering has depended heavily on teacher's perception. Recognizing the role of teaching (including Physics teaching) in language training will help teachers become conscious while designing…

The periodic table is an essential topic in the teaching and learning of science at all education levels, as it contains information about the main physical and chemical properties of the different elements constituting the matter. However, becoming familiar with the facts behind the periodic table such as the element names and/or symbols, their…

The study examined the effect of context-based learning (CBL) and gender influence on chemistry students' acquisition of integrated science process skills (ISPS). Two research questions guided the study. This study used a quasi-experimental research design with a sample of 192 participants who had an average age of 15. Three instruments were used…

An important step in learning to use math in science is learning to see symbolic equations not just as calculational tools, but as ways of expressing fundamental relationships among physical quantities, of coding conceptual information, and of organizing physics knowledge structures. In this paper, I propose "anchor equations" as a…

Background: A key aspect of STEM learning is the use of visual representations for problem solving. To successfully use visuals, students need to make sense of how they show concepts and to fluently perceive domain-relevant information in them. Adding support for sense making and perceptual fluency to problem-solving activities enhances students'…

In this study, we document pre-service teachers' (PSTs) opportunities to learn about planning for equitable and ambitious instruction during clinical placements. We also test whether these opportunities vary by the level of participants' perceived congruence between the vision of science teaching supported in their university coursework and the…

The main objective of the present study was to evaluate the effectiveness of two learning methodologies in a Plant Tissue Culture course of a Biotechnology degree--lecture-based and hybrid project-based learning--in which a project assignment was included. The effectiveness of these two systems was compared based on the students' knowledge…

This paper illustrates a year-long case study investigating in-service teachers' needs and mentor's practices in implementing cutting-edge research science topics as nanotechnology and plastics in the ocean in primary education. In a Community of Learners design and with the support of a mentor, ten primary teachers implemented in 6th grade…

Research has demonstrated that gesture produced during conversation can provide insights into scientific thinking and can aid scientific communication in adults and school-aged children. However, to date, there has been a limited exploration into the role of gesture in supporting young children's science communication, and how this is underpinned…
