This research focuses on "BioScientist," a digital game-based, inquiry-based learning program embedded in the biology curriculum that develops inquiry skills in 8th-grade students. The aim of this paper is to demonstrate a combination of elements of digital game-based learning (DGBL) with inquiry-based learning (IBL) through…

This study aims to examine the effect of conceptual understandings related to anion-cation, acid-base, ionic-covalent, metal-nonmetal, and number of protons-number of electrons concept pairs taught in the periodic table to 8th grade students with the 5E learning model supported by concept maps. The study was conducted among 100 (50 in the…

Research shows that motivation is a critical precursor to students' science achievement. However, research on the topic yields ambiguous results in different cultural contexts. While the positive association between motivation and science achievement has been evidenced universally, the relatively predictive effect and strength of different…

Although there has been extensive research on students' understanding of the particulate nature of matter (PNM), there is still a lack of research on contexts that can be used to teach this challenging topic. In a previous design-based research study, the authors developed a teaching-learning sequence (TLS) on the PNM in the context of crystal…

In the present research, the "DNA Model with Clothespins" activity was designed to teach the subjects of nucleotide, DNA, and DNA replication, which are abstract subjects of science. The aim of the research, which was carried out with 20 students in 8th grade, was to examine the effects of the activity on students' achievement on the…

Effective science instruction in a blended learning approach is synonymous with the strategic use of instructional videos (IVs) to fill the gap in teacher support. This study aims to determine the IVs' effectiveness in improving students' concept retention and overall learning experiences. The experimental group was exposed to instruction…

This study examined the impact of sense of belonging on student engagement in math and science classrooms at an all-girls middle school. The sample was comprised of 129 seventh and eighth-grade students in three math classrooms and three science classrooms in an independent, urban all-girls middle and high school. My research design applied…

The history of science (HOS) has played an important role in science curricula for teaching about science. However, historical information in science textbooks is often de-contextualized, coupled with limited class time and teaching barriers, and thus fails to help students understand the dynamic process of scientific development. This research…

Mendelian genetics are essential for students seeking to comprehend the complexities of inheritance; although fundamental, these biology concepts are difficult for students to understand. This study examined the effectiveness of task-based learning (TBL) in enhancing the students' conceptual understanding of the Patterns of Mendelian Genetics. A…

This research explores whether classroom life (CL), textbooks (TE), and learning initiative (LI) are mediators between instruction (P) and science performance, as well as whether these mechanisms are moderated by gender. 484 eighth grade students completed the questionnaire with four subscales of P, LI, TE, and CL. For the needs of triangulation…

Creative educational methodologies capable of engaging students in interactive, enjoyable learning help to lessen students' anxieties and motivate them. In this context and with the objective of making easier the learning of the chemical symbols and periodic table as well as introducing the concept of chemical formula, we have designed the…

Organic chemistry, also known as stereochemistry, is a subject considered to be notably complex for students to understand. Knowledge construction in stereochemistry might demand the ability to imagine or visualise the distribution of atoms. For students with insufficient spatial ability, this could be confusing. This study aimed to explore…

Ocean currents play an important role in regulating the Earth's climate by redistributing ocean heat around the planet. One important climate phenomenon that includes several large ocean currents is the Atlantic Meridional Overturning Circulation, which is the process of warm surface currents in the North Atlantic Ocean moving to the Arctic to…

The aim of this study is to examine the effect of 'Pressure', which is taught by supporting scientific stories, on the academic achievement, attitude and motivation of 8th grade students. In this study, which aims to investigate the effects of scientific stories on student achievement, motivation and attitudes in science education, a…

This study aimed to develop alternative laboratory experiments (ALEs) in Chemistry 8 and evaluate the perceived improvement of the students' basic science process skills after utilizing the material. This employed a mixed method of research. Initially, a self-assessment survey questionnaire was used to determine the basic science process skills of…
