The main purpose of this study was to investigate the effect of the Context-Based Approach (CBA) enriched by Prediction-Observation-Explanation (POE) on 5th grade students' conceptual understanding of the States of Matter, Heat and Temperature. In this study, quantitative and qualitative data collection methods were employed. The quantitative…

In this study, it was aimed to determine the effects of the learning process based on the 5E Model Supported by Real Life Based Context in the Unit of Force and Energy in the course of Science on the conceptual understanding levels of the students at the seventh grade which are measured various techniques. The research was designed with…

The flow of genetic information from DNA to RNA to protein, otherwise known as the "central dogma" of biology, is one of the most basic and overarching concepts in the biological sciences. Nevertheless, numerous studies have reported student misconceptions at the undergraduate level of this fundamental process of gene expression. This…

Background: Many researchers agree that students, especially primary students, have learning difficulties on the "Particulate Nature of Matter" unit. One reason for this difficulty is not considering individual differences for teaching science. In 4MAT model learning, environment is arranged according to individual differences. Purpose:…

The efficacy of a teaching sequence designed for a specific content of learning of electrochemistry is described in this paper. The design of the teaching draws upon theoretical insights into perspectives on learning and empirical studies to improve the teaching of this topic. A case study involving two classes, the experimental and baseline…

This paper deals with the nature and the level of difficulty of teaching and learning physics in the first year of undergraduate engineering schools in France. Our case study is based on a survey regarding a classic and basic question in applied physics, and which was conducted with a group of second-year students in a post-baccalaureate 1…

A characteristic feature of scientific knowledge is the high degree of coherence and connectedness of its conceptual structure. This notion is also behind the widely accepted instructional method of representing the concepts as networks. We suggest here that notions of explanatory coherence and deductive coherence naturally connect the structure…

This article presents a case for equipping science teachers with the necessary skills needed to enact dialogical argumentation-based classroom discourses. Even though teachers are required to scaffold knowledge construction in the classroom, it appears that not much prominence has been dedicated to exploring alternative or novel approaches to…

Much research in educational technology has focused mainly on how the technology supports student learning. Research on what teachers need to know in order to appropriately incorporate technology into their teaching has been limited because of the lack of theoretical grounding for understanding teachers' cognitive process of technology integration…

Weight is one of the basic concepts of physics. Its gravitational definition accommodates difficulties for students to understand the state of weightlessness. The aim of this study is to investigate the effect of materials based on 5E teaching model and related to weightlessness on science student teachers' learning. The sample of the study was 9…

This investigation focused on the effects of a treatment package including multiple exemplar training, time delay, and a self-directed learning prompt (KWHL chart) on students' ability to complete an inquiry lesson independently and generalize to untrained materials. Three middle school students with moderate intellectual disabilities learned to…

As research faculty with expertise in the area of host-pathogen interactions (HPI), we used a research group model to effect our professional development as scientific educators. We have established a working hypothesis: The implementation of a curriculum that forms bridges between our seven HPI courses allows our students to achieve deep and…

Science teachers continually search for effective ways to help students make sense of science concepts and principles. For students to learn to think more like scientists, science teachers must decrease the number of lectures and "follow-the-recipe" laboratory experiments and increase the use of activities that incorporate student inquiry.…

In April 2003 the first European Science Olympiad took place in Dublin City University in Ireland. In this competition second level students were asked to carry out a number of tasks involving biology, physics and chemistry. Students had qualified initially in competitions in one of these subjects and were organised into integrated teams which…
