The study examined the effectiveness of concept mapping in improving students' academic performance using an embedded mixed-methods design. It involved Srinka Secondary School's grade 10 biology teacher, students, and department head in the study and gathered data from them by using biology achievement tests, interviews, and focus group…

Educators have struggled with maintaining student engagement in science, especially as students transition from primary to middle school and upper grades (Vedder-Weiss & Fortus, 2012). A recent push in science education has been the adoption of the Next Generation Science Standards (NGSS), released in 2013, whose development was guided by…

This quasi-experimental study aimed to determine if there is a statistically significant difference in student test scores when a modified instructional sequence in middle school science is used versus the instructional sequence suggested by the Commonwealth of Virginia. The Grade 8 science cumulative Standards of Learning (SOL) test results from…

BrainPOP Science is a research-based program that has been shown to be effective in improving and quickly developing students' scientific reasoning skills. This white paper presents a comprehensive case study conducted in school districts in the Southeastern United States. BrainPOP Science is one of the leading supplemental middle school programs.…

In this research, we have explored the possible differences in students' performance in grade nine chemistry exams that could have been influenced by a different instructional approach in grade eight. We compared two groups of students: one group had received a transmissive propaedeutic approach in grade eight (especially related to the memorising…

This paper proposes a blended teaching design model on WeChat Platform-based SPOC and carries out an empirical study of its applicability and effectiveness in lower-secondary school science teaching. Participants were from two eighth grade classes with different academic performance, and after conducting the same blended teaching, it was found…

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…

Argumentation is fundamental to science education, both as a prominent feature of scientific reasoning and as an effective mode of learning--a perspective reflected in contemporary frameworks and standards. The successful implementation of argumentation in school science, however, requires a paradigm shift in science assessment from the…

This study examined the impact on the motivation of students toward learning physics upon applying the Nikola Tesla Center (NTC) learning system. The research was conducted using a quasi-experiment with a pretest-posttest non-equivalent control group design. The participants considered were a large group of 1371 students, from various grades and…

Purpose: The purpose of this study is to determine the impact of an Inquiry-based Flipped classroom model on the conceptual understanding and science process skills of junior high school students in the Philippines. Method: A two-group pretest/post-test design was conducted on 55 Grade 9 students for the study. One group received instruction using…

Student' achievement in science can be affected by teacher subject matter knowledge, ineffective instructional methods, and lack of student engagement. Although all schools provide professional development opportunities, not all teachers choose to engage in a program that provides teaching and learning through experiential techniques for the…

Optics is a core field in the curricula of secondary physics education. In this study, we present the development and validation of a test instrument in the field of optics, the ray optics in converging lenses concept inventory (ROC-CI). It was developed for and validated with middle school students, but can also be adapted for the use in higher…

THS is applied to Science High Schools, Social Sciences High Schools, Anatolian Technical Programs of Vocational and Technical Anatolian High Schools and Project schools for student selection. With THS, approximately 10 percent of more than one million students are placed in a secondary education institution based on their preferences. The purpose…

In this study, in line with TIMSS 2019 data, 8th grade students' school engagement in the Turkish education system and various variables in the field of science and mathematics, which are thought to be related to school engagement, were examined with the Random Forest method, a method amongst data mining methods. This research focuses on student…
