Chemistry lesson should be supported with experiments to understand the lecture effectively. For safety laboratory environment and to prevent laboratory accidents; chemical substances' properties, working principles for chemical substances' usage should be learnt. Aim of the present study was to analyze the effect of experiments which depend on…

Building a robot from scratch in an educational context can be a challenging prospect. While a multitude of projects exist that simplify the electronics and software aspects of a robot, the same cannot be said for construction systems for robotics. In this paper, we present our efforts to create a low-cost do-it-yourself construction system for…

In this paper, we present a teaching module about stellar structure, functioning and evolution. Drawing from literature in astronomy education, we designed the activities around three key ideas: spectral analysis, mechanical and thermal equilibrium, energy and nuclear reactions. The module is divided into four phases, in which the key ideas for…

The aim of the present study was twofold. First, we aimed to replicate the findings of previous studies which had showed a substantial improvement on procedural and epistemological knowledge after direct instruction and their maintenance in time. Second, we aimed to examine the dynamic relationships of the procedural (control of variables…

Organic chemistry has its own representational language and as with any language, any barrier with the language makes understanding the message difficult. In this article, we describe the design of an open education resource that empowers students to master this language. We also describe the structure and findings of a pilot study designed to…

This study uses the Taiwan Programme for International Student Assessment (PISA) 2006 Main Survey and Taiwan PISA 2015 Field Trial survey datasets to investigate how self-evaluated values (i.e. personal and general) and cognitive factors (i.e. self-efficacy and self-concept) of two groups of Taiwanese 15-year-old students separated by 8 years of…

School science practical activities have been criticised for exposing learners to a series of phenomena disconnected from the conceptual frameworks needed to understand them. Such activities are successful in the "domain of observables" but not the "domain of ideas". Few resources exist for classroom teachers wishing to improve…

The science education literature shows that students have difficulty understanding what causes the seasons. Incorrect explanations are often due to a lack of knowledge about the physical mechanisms underlying this phenomenon. To address this, we present a module in which the students engage in quantitative measurements with a photovoltaic panel to…

This study investigated the hypothesis that prompting students to self-assess their interest and understanding of science concepts and activities would increase their motivation in science classes. Students were randomly assigned to an experimental condition that wrote self-assessments of their competence and interest in science lessons or a…

For the study of biology in an undergraduate classroom, a classroom exercise was developed: an analogy role-play to learn mechanisms of gene transcription and protein translation (central dogma). To develop the central dogma role-play exercise, we made DNA and mRNA using paper sheets, tRNA using a wire dress hanger, and amino acids using Lego®…

This study aims to explore the influence of nature of science (NOS) activities based on explicit-reflective and historical approach on preservice elementary teachers' views of NOS aspects. Mixed-method approach including both qualitative and quantitative methods was used. The sample consisted of 83 preservice elementary teachers of a public…

Despite many research studies showing the effectiveness of teacher application of child-centered learning in different educational settings, few studies have focused on teaching and learning activities in Pre-Schools. This research investigates the effect of child centered methods on teaching and learning of science activities in preschools in…

The goal of the Family Science Night (FSN) described in this article was to involve culturally and linguistically diverse families in school life so that students would be more vocal, successful, and interactive in science class. The project would also demonstrate to the students that their teacher valued their input in the classroom. The setting…

This study examined the effectiveness of Argument-Driven Inquiry (ADI) as an instructional model in a general chemistry laboratory course. The study was conducted over the course of ten experimental sessions with 125 pre-service science teachers. The participants' level of reflective thinking about the ADI activities, changes in their science…

This paper describes the utility of using simulated, rather than real, student solutions to problems within a peer-assessment setting and whether this approach can be used as a means of improving performance in chemical calculations. The study involved a small cohort of students, of two levels, who carried out a simulated peer-assessment as a…
