There is a tradition in primary classes of using rich authentic activities to teach science. The idea of pupils learning science through experiment and discovery is appealing. But this is not how children are taught in other subjects. When children learn to read, there are tiny steps, mastering each one before moving onto more challenging books.…

This paper investigates whether and how primary school students improve their epistemic understanding about a particular aspect of the nature of inquiry (NOSI), namely, the 'non-linear nature of inquiry' through an explicit-reflective or implicit instruction. The sample consisted of 30 5th grade students, who were randomly divided into two groups:…

This study compares direct instruction to two constructivist approaches, namely experimentation and problem-based learning, in fifth-grade science learning in Hong Kong. Constructivist instructional approaches, contrary to direct instruction, stress on students' active role in constructing knowledge in learning. Experimentation and problem-based…

The aim of this research is to examine the effectiveness of the concrete-pictorial-abstract learning strategy presented with the direct teaching method in teaching the subject of mixtures, which is one of the science subjects, to students with intellectual skills disabilities. The study used multiple-probe model with a probe phase, one of the…

Background: The question of the efficiency of withholding answers and the physical manipulation of material in science education has become the target of a large number of researchers (proponents of the Cognitive Load Theory) in recent years. However, no research has been found examining the contribution of these elements of teaching to the…

Temperature and heat are difficult concepts for children to grasp due to their abstractness. An image-to-writing approach, guided by the visualisation practices of scientists, was designed to engage elementary students with constructing images to represent their ideas about phenomena and translating these images into text using scientific…

Structure-property reasoning (SPR) is one of the most important aims of chemistry education but is seldom explicitly taught, and students find structure-property reasoning difficult. This study assessed two design principles for the development of structure-property reasoning in the context of demonstrations: (1) use of a POE task…

The purpose of this study is to implement an intervention designed to develop background knowledge and investigate its effects on science proficiency for students who are at risk for failure. Pretest scores for 130 students were analyzed to identify students with prior knowledge deficits that may put them at risk for failure. Of the 44 students…

Learning physics at SMA, does not only involve memorizing facts, but it also engages the students in solving more problems without delay and attaining a real learning achievement. This study aimed to analyze the effect of project-based learning (PjBL) compared with direct instruction (DI) and student procrastination on student cognitive…

Instructional explanations have sometimes been described as an ineffective way to teach science, representing a transmissive view of learning. However, science teachers frequently provide instructional explanations, and students also offer them in cooperative learning. Contrary to the transmissive view regarding explanation, studies suggest that…

Among a sample of 2,071 Australian high school students nested within 188 science classrooms, the present study explored the role of science teachers' "load reduction instruction" (LRI; instruction that seeks to reduce cognitive load by appropriately balancing explicit instruction with guided autonomy) in student- and classroom-level…

The study aimed to investigate the retention of acquired argumentation and NOS conceptions among grade 10 students three months after the treatment. Thirty-six grade 10 students in two intact sections, randomly assigned into the Treatment and Comparison groups, participated in the study. The participants engaged in a treatment that lasted for four…

A qualitative pre-/post-test case study was conducted to explore the influence of inquiry-based education in eliciting learners' understanding of the particulate nature of matter in the gaseous phase. Two grade four classes (n=116) were conveniently and purposively sampled from two farm schools in Pretoria, South Africa. Data was collected through…

Scence educational standards are increasingly emphasising on argumentation skills. However, students' argumentation skills are often not developed well as their experience of science knowledge in schools is often in the form of uncontested facts. This research asserts that argumentation skills should be developed through explicit teaching of…

Literature review shows that many primary school teachers have poor understanding of basic astronomy contents. Therefore, the aim of the study was to introduce specific astronomical content to in-service primary school teachers through two didactic games, to evaluate the didactic games and the teachers' knowledge and understanding before and after…
