The goals of the study were as follows: i) to design an active science learning activity on stoichiometry for grade 10 students, ii) to evaluate the academic achievement of grade 10 students after receiving an active science learning activity on stoichiometry, and iii) to investigate the perspectives of grade 10 students regarding an active…

This study examines the role of shadow education as a contributor to educational inequality in South Korea. Using data from the Korean Educational Longitudinal Study (KELS), this paper analyzes the effects of private tutoring at 10th and 12th grade level on College Scholastic Aptitude Test (CSAT) scores. We reduce biases in prior research by using…

This study explores lower secondary school teachers' arguments and perceptions for using a 26-point grading scale (26-PGS), and gender differences in assessment practice. An explanatory sequential design was conducted. First, teachers (n = 6) assessment of students' text (n = 182) was analysed. In the subsequent phase, an open-ended questionnaire…

Chemistry academic engagement has received considerable attention for its role in enhancing students' learning and overall development. As a significant factor influencing students' chemistry improvement, research on chemistry academic engagement has emerged as a focal point. However, the methods to improve students' chemistry academic engagement…

Developing structure sense is an important part of learning algebra. We investigated learners' structure sense of algebraic expressions involving brackets. This led us to propose the constructs "surface structure" sense and "systemic structure" sense. Using a random sample of 58 Grade 10 learners scoring above 40% in a test, we…

Purpose and Method of Study: This study aimed to determine variables or combinations of variables that impact the hope levels of tenth- to twelfth-grade students at a large urban public school in Oklahoma. While many factors influence students' hope, there is little information about the impact of HAE and PSC, in addition to the variables grade…

This study explores the integration of socio-humanitarian safety components into the chemistry curriculum for secondary education, emphasizing how contextual and competency-based assessments can enhance the preparedness of future chemistry teachers. Employing a mixed-methods approach, the research evaluates the effectiveness of traditional,…

Purpose: Through the action research study, this paper aims to examine how e-portfolios improve students' critical, reflective and creative thinking as part of higher-order thinking skills (HOTS). Besides, this paper also explores how e-portfolios enhance students' speaking skills. The study is carried out to improve the current state by…

Completion of higher-level mathematics courses in secondary school is advantageous for success in many university-level science, technology, engineering and mathematics courses. Based on survey data from 942 Year 10 students from Western Australia, the Year 11 mathematics course choices made by girls and boys were compared. Findings indicated that…

Making drawings can help students avoid and overcome difficulties they encounter when solving real-world (or modeling) problems. However, many students do not make drawings spontaneously. In the present study, 132 students in Grades 9 and 10 were randomly assigned to the experimental conditions "with situational or mathematical drawing…

Developing and using models to make sense of phenomena or to design solutions to problems is a key science and engineering practice. Classroom use of technology-based tools can promote the development of students' modelling practice, systems thinking, and causal reasoning by providing opportunities to develop and use models to explore phenomena.…

Learning progressions (LPs) serve as frameworks for understanding the level of complexity of students' ideas within a domain. Multifaceted LPs contain multiple interrelated constructs where increased knowledge in one construct may increase knowledge of a separate construct. While it is challenging to identify and test these contingencies between…

Academic self-concept and achievement have been found to be reciprocally related across time. However, existing research has focused on self-concept and achievement scores that have been averaged over long time-periods. For the first time, the present study examined intraindividual (within-person) relations between momentary (state) self-concept…

In this article, we investigate how a process drama can be used in efforts against school bullying in a new digitalised society, specifically, what kinds of initiatives Norwegian adolescents make use of in process drama as anti-bullying prevention and what kinds of attitudes towards this kind of prevention work they emphasise. In the project Drama…

The purposes of the study were to investigate the effectiveness of the K-W-D-L technique on grade 10 students' mathematical problem-solving abilities and to study the students' attitudes toward learning mathematics after participating in learning management designed using the K-W-D-L technique. The participants were 40 grade 10 students in a…
