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 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…

Drawing, constructing, and explaining a model of a given abstract phenomenon is a challenging task. In this study, students were engaged in the "Project-Based Inquiry Science (PBIS)-Air Quality" learning unit, as part of their chemistry curriculum. The study aim is to determine how well students understand chemistry conceptually after…

Given the strong relationships found between high-level learning strategies such as drawing and summarising, and student comprehension and performance, we have seen an increase in drawing-to-learn strategy research. Despite the trend and promise of drawing-to-learn, many of the studies have been limited to high school and undergraduate chemistry…

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…

Recently, potential effects of STEM activities on students in science education are among important research topics. Therefore, in this study, the effect of STEM activity practices on the scientific creativity of middle school students was investigated. The research sample consists of 98 (experimental group = 50 students, control group = 48…

At an Extension youth agricultural science center, our team developed and pilot tested a five-lesson weather and climate science curriculum for middle school-aged youths. As part of the endeavor, we conducted an item analysis of the five worksheets used across the lessons and determined relationships between worksheet scores and pretest/posttest…

The Japanese lesson study (JLS) model for curriculum development has seen limited application to middle school science classrooms. The JLS model was used to develop and refine three hands-on activities focused on four major eighth grade science topics from the California curriculum. Prior assessments of these topics showed limited understanding by…

Practical activities are the main activities of learning biology whose implementation is rarely evaluated. This study aimed to determine the quality of biology practicum which includes planning and implementation of biology practicum and student learning outcomes thereafter. The population in this study was students, teachers and and laboratory…

Teaching science concepts for conceptual understanding has its challenges. Promoting conceptual change in the science classroom can be difficult because most concepts are complicated and counter-intuitive. This dissertation research aimed to determine the effect of teaching for conceptual understanding models on pre-service teachers' conceptual…

Teaching approaches in some school are still concentrating on memorizing. Teachers have to make the learning is meaningful for the students. One of the alternative tools is by using Brain-Based Learning. The purpose of this study is to investigate the effect of Brain-Based Learning on students' concept mastery in learning electric circuit for…

This study examined contributions of academic ability tracking, disciplinary attitudes (science anxiety and self-efficacy), and discipline-specific literacy skills (science and academic vocabulary knowledge) to students' science achievement in a sample of 104 Grade 8 students (78% current or former English learners [ELs]) enrolled in high- versus…

Over the last two decades, online education has become a popular concept in universities as well as K-12 education. This generation of students has grown up using technology and has shown interest in incorporating technology into their learning. The idea of using technology in the classroom to enhance student learning and create higher achievement…

The purpose of this study was to investigate the effectiveness of the experimental system design related to plasma state on the gifted students' understanding on the subject of the plasma state. To test the research hypothesis, one group pretest-posttest research model was carried out with 18 eighth-grade (4 girls and 14 boys) gifted students in…

Inquiry-based teaching methods have been found to enhance students' abilities to understand the process of scientific inquiry. The purpose of this study was to determine if middle school students taught through an inquiry-based teaching approach consisting of scientific skill development, scientific knowledge, and scientific reasoning were more…
