Scientific literacy is an important skill for students' success, given the characteristics of today's society. However, not all students have a natural predisposition toward science, chemistry in particular. Considering the relevance of transdisciplinary learning, schools should foster the scientific abilities for which students may have less…

Research has shown that spatial ability plays a key role in understanding STEM (Science, Technology, Engineering, and Mathematics) content, including chemistry. Conservation of Matter (CoM) is an essential but challenging topic for chemistry students of all ages to grasp; it is often taught in a way where students memorize it but do not learn what…

The aim of this study is to examine the effects of computer-based analogy (CBA) used in science teaching in terms of the unit of Structure and Properties of Matter on seventh-grade students' academic success. The attitudes of students against science teaching lesson were also described in this study. This study was applied to 60 seventh-grade…

The goal of this research is to provide a rich set of connections between two fields: (i) Nanoscale science and technology (NST) and (ii) topics from a common middle school physics curriculum. NST is emerging as one of the most promising new fields of the 21st century, which is one of the many arguments for including NST topics in secondary…

The purpose of the study is to determine the knowledge and awareness of gifted children receiving education in the Science and Art Center on nanotechnology. The descriptive survey model was used in the study. The purposeful sampling method was chosen and a total of 160 students receiving education in two Science and Art Centers located in the city…

Most junior high school students considered chemistry as a complicated science subject with an abstract concept, symbols, and terms that must be memorized. The difficulty of learning chemistry made students had low positive perceptions of chemistry. It was needed the right ways to introduce chemistry to them. The purpose of the multiple case study…

Various sequences for teaching genetics have been proposed. Three seventh-grade biology textbooks in Taiwan share similar key knowledge assemblages but have different knowledge arrangements. To investigate the influence of knowledge arrangements on student understanding of genetics, we compared students' reading comprehension of the three texts…

The present study examined the cognitive factors that influence children's physical science learning from a multimedia instruction. Using a causally coherent text and visual models, we taught 4th- and 7th-grade children about the observable and molecular properties of the three states of water. We manipulated whether the text was read by a tutor…

In this study, we investigated whether the understanding of the particulate nature of matter by students was improved by allowing them to design and evaluate molecular animations of chemical phenomena. We developed Chemation, a learner-centered animation tool, to allow seventh-grade students to construct flipbook-like simple animations to show…
