The aim of present research was to examine the effects of interdisciplinary teaching approach on teaching the topic of proteins. In the research, unequal control group model- one of the quasi-experimental research designs was used. The experimental group included 16 students (8 female and 8 male) whereas the control group included 14 students (6…

The study assessed the effect of concept map on achievement and classroom management of 7th grade students. Three elementary schools were purposively selected in Silchar town of Assam, India. The 7th grade students (n = 36), of 'School I' was assigned to lecture cum discussion approach, 34, students (n = 34) of 'School II' was assigned to Spider…

Some research findings showed that Indonesian students' critical thinking skills below average, especially those who have a low academic ability; even though that skills are needed to face this 21st century. There should be a strategy to train students to develop their critical thinking, one of them is by implementing an appropriate learning…

In this study, the use of concept cartoons in a particle structure of matter unit was investigated using the flow map of 7th-grade students' academic achievement. The development of their cognitive structures and thoughts about concept cartoons was analyzed. 27 experimental and 27 control group students who were studying in the 7th grade…

Purpose of Study: The aim of this study is to investigate the nature of pre-service biology teachers' metaconceptual processes that were active as they participated in metaconceptual teaching activities. Methods: Several instructional activities, including poster drawing, concept mapping, group and class discussions, and journal writing, were…

In many science education practices, students are expected to develop an understanding of scientific knowledge without being allowed a view of the practices and cultures that have developed and use this knowledge. Therefore, students should be allowed to develop scientific concepts in relation to the contexts in which those concepts are used.…

A common hypothesis is that students will more deeply understand dynamic systems and other complex phenomena if they construct computational models of them. Attempts to demonstrate the advantages of model construction have been stymied by the long time required for students to acquire skill in model construction. In order to make model…

In this paper, we explore the use of concept maps (Cmaps) as instructional materials prepared by teachers, to foster the understanding of chemistry. We choose fireworks as a macroscopic event to teach basic chemical principles related to the Bohr atomic model and matter-energy interaction. During teachers' Cmap navigation, students can experience…

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…

This article details a study that investigated 55 elementary pre-service teachers' content knowledge about density. Using a mixed-methods approach, pre/post face-to-face interviews and pre/post concepts maps (Cmaps) were used as data to document changes in teacher knowledge which occurred over a 15-week science methods course. Thematic analysis…

This study evaluated the effect of students' academic achievement on identified difficult concepts or topics in Senior Secondary School Biology in Delta State, Nigeria. The study was quasi-experimental and the design was a 2X2 factorial non-randomized pretest-posttest control group design. The sample was drawn from intact classes from four…

This study explored elementary pre-service teachers' content knowledge for dissolving before and after an instructional intervention over a 15-week science methods course. Pre-service teacher knowledge was examined using pre/post concept maps (Cmaps) and drawings with narrative descriptions. A mixed methods approach was used for both data…

Improving students scientific explanations is one major goal of science education. Both writing activities and concept mapping are reported as effective strategies for enhancing student learning of science. The purpose of this study was to examine the effect of a teaching model, named the DCI model, which integrates a Descriptive explanation…

The green chemistry course taught at Westminster College (PA) incorporates nontraditional teaching techniques and texts to educate future chemists about the importance of using green chemistry principles. The course is designed to introduce green chemistry concepts and demonstrate their inherent necessity by discussing historical missteps by the…

It generally is accepted that concept mapping has a noticeable impact on learning. But literatures show the use of concept mapping is not benefit all learners. The present study explored the effects of incorporating computer-based concept mapping in physics instruction. A total of 61 9th-grade students participated in this study. By using a…
