Redox reaction is a core chemical concept. However, its abstract nature makes it very difficult for students. Students' conceptual structure reflects their mastery of concepts, which helps teachers implement targeted educational strategies. This study aimed to explore the conceptual structures of redox reaction held by students (grades 10 to 12)…

Initial teacher education should mould well-rounded teachers proficient in scientific investigations, and advocate sustainability amid global ecosystems' degradation. The research sought to explore pre-service science teachers' views concerning scientific investigations and sustainable development goals, and synergy between skills and different…

Students' problem-solving strategies and the differences among strategy groups were explored by analyzing the process data collected during student interactions with computer-based science items. Data were gathered from 1516 eleventh-grade students from 4 schools in China. Analyses of the sequences of students' response actions revealed that the…

Although integrating the history of science (HOS) into teaching has long been recommended in science education research, studies have revealed conflicting results on its effectiveness. These are mainly due to the need for more studies in this context. Therefore, this research aimed to explore the impact of HOS teaching on science process skills,…

Relevant literature has an unexplored question on how prediction-observation-explanation (POE) worksheets affect science process skills of students with mild intellectual disabilities (SMID). Therefore, this research aimed to examine the effect of POE worksheets developed for the "matter and its nature" subject on SMID's science process…

Geographical practice power is a key competency essential for students' overall development. It is, therefore, important to understand its concepts, contexts, and content. Practical activities following scientific and operable principles in real geographical situations would enable students to unleash their potential across the curriculum. The…

Science education focuses on the methods of thinking about and using process skills rather than memorizing scientific facts. 5E educational model aims to learn by discovering scientific knowledge and engaging students in learning environments. The aim of this study was to examine the articles in the field of education related to the 5E educational…

The presented research focuses on verifying the confluent application of concept mapping (CM) and socio-scientific issues (SSI) according to the value-laden and moral dilemma orientation to construct problem-solving performance. This research sets up some perspectives for all 146 participants, including 139 students and 7 experts. All findings…

The Many-Facet Rasch model is frequently used to analyse and minimize disparities in rater (judge) severity in performance evaluations, in which raters assign scores to test-takers' performances. In this research, the aim of the present study was to analyse science teacher candidates' laboratory activities by using the Many-facet Rasch model.…

Nowadays, the assessment of student performance has become increasingly technology-based, a trend that can also be observed in the evaluation of scientific reasoning, with more and more of the formerly paper-based assessment tools moving into the digital space. The study aimed to examine the reliability and validity of the paper-based and…

Ability to adequately analyze educational situations is essential not only for (pre-service) teachers' occupational decisions, but also for their own professional development. This study represents an evaluation of the observation practice aimed at pre-service chemistry teachers' (N = 12) professional vision development. They attended chemistry…

Today science teachers are expected to understand the nature of environmental education, and be competent in skills, methods, and procedures relevant to a science discipline. The purpose of this research was to explore pre-service science teachers' views with regard to environmental education, investigation conducted during a freshwater ecosystem…

The Lawson's Classroom Test of Scientific Reasoning (LCTSR) is a popular instrument that measures the development of students' scientific reasoning skills. The instrument has a two-tier question design, which has led to multiple ways of scoring and interpretation. In this research, a method of pattern analysis was proposed and applied to analyze…

Visuo-semiotic models, such as Lewis structures and ball & stick models, are widely used to enhance students' learning. However, there is limited research about the impact of these models on specific visuo-semiotic reasoning skills. In the current research, we aimed to determine the extent to which physical molecular models could enhance…

This research explored the level of students' basic and integrated Science Process Skills (SPS) based on their academic majors, gender, and grade levels at the end of a chemistry laboratory course. Convenience sampling was used to select 298 undergraduate students at the Yogyakarta State University, Indonesia. A survey method was used, and the…
