Teachers are increasingly expected to incorporate Project-based learning (PBL) pedagogy to teach science. While teachers' definitions and challenges in the use of PBL are widely studied, very few studies focus on the development of a teacher's knowledge of the use of PBL over multiple projects. The current research is an in-depth case study aimed…

Confusion may benefit learning when it is resolved or partially resolved. Metacognitive strategies (MS) may help learners to resolve confusion when it occurs during learning and problem solving. This study examined the relationship between confusion and MS that students evoked in Betty's Brain, a computer-based learning-by-modelling environment…

The main purpose of this research is to determine the effect of the volume of concept on the level of understanding the relationship between concepts. The mixed method was used in the research. Volume of concept form, concept map form and puzzle scales were used to collect quantitative data. Qualitative data was collected through a fully…

We present the development and validation of a construct map addressing introductory quantum mechanics topics at the high school level, as a subset of a larger learning progression on quantum mechanics. Topics include energy quantization, photon absorption and emission, the Heisenberg uncertainty principle, atom stability, orbitals, wave function,…

The purpose of this activity is to demonstrate science teaching and assessing what is learned via using concept maps. Concept mapping is a technique for visually representing the structure of information. Concept mapping allows students to understand the relationships between concepts of science by creating a visual map of the connections. Concept…

Describes the exploratory assessment of strategy for learning redox reactions in High School, which seeks to prevent students from developing memoristic and mechanical skills, in addition to emphasize the experiences of daily life that go unnoticed or unexplained to the student in the classroom and at the same time are able to incorporate the key…

This study aims to conduct a detailed investigation on the effect the use of concept mapping, as an individual learning tool, has on students' success in learning the concept of gravimetric analysis. This study applies a case study research design to quantitatively examine the effect of the use of concept mapping and to conduct a detailed…

Teaching biology is characterized by a great number of concepts and facts. It is very difficult to concisely represent all important concepts and facts. In order to effectively present important concepts such as pollination and pollinators, concept maps have been applied. In particular, the pedagogical experiment was applied to determine whether…

Momentum is a foundational concept in physics. Although it is often taught in introductory mechanics courses, there are a limited number of studies on this topic in the literature. The results from these studies have consistently shown that students have difficulties in understanding momentum, especially the connections between net force, time,…

Creativity has become an increasingly important competence in today's rapidly changing times, especially for school graduates who strive for pursuing a technical or scientific career. But creativity has not been integrated in the lessons or curricula of STEM subjects. To successfully integrate it in the classroom, it is important to investigate…

This work presents a proposal for the teaching-learning of the concept map technique applied to the Natural Sciences course in the second year of Compulsory Secondary Education (ESO, according to its initials in Spanish). Two sessions have been designed, one of which is an instructor-led session to learn the technique and another is a session in…

The purpose of this mixed-methods study was to explore the effect of within-gender and cross-gender team argumentation on seventh graders' science knowledge and argumentation skills in a computer-assisted learning environment in the United States. A total of 58 students were engaged in the collaborative within-gender team argumentation process…

Background: Enhancing students' metacognitive abilities will help to facilitate their understanding of science concepts. Purpose: The study was designed to conduct and evaluate the effectiveness of a repertoire of interventions aimed at enhancing secondary school students' metacognitive capabilities and their achievements in science. Sample: A…

In searching for effective ways to combine science/chemical education with EE/ESD, new didactic materials were designed and produced focussing on biogeochemical cycles and their connection to sustainable development. The materials were experimentally applied in 16 Greek schools under the newly introduced compulsory "school project" which…

Students bring with them their own misconceptions to the science classes and it becomes a barrier in developing new concepts. Therefore, identifying misconceptions is an essential component in teaching science. The objective of this study was to identify 10th grade students' misconceptions on plant transport with the use of two-tier diagnostic…
