The objectives of this research were 1) to study the problems of stress and depression among Grade 12 students; 2) to investigate the machine learning technique in analyzing and predicting stress, depression, and academic performance among Grade 12 students; and 3) to evaluate the stress and depression prediction platform. Students from schools in…

The Monitoring the Future (MTF) study monitors historical and developmental changes in substance use prevalence among key subgroups of the general U.S. adolescent and adult population. The current study first devised and evaluated a cohort-specific pooled analysis weighing procedure for the MTF panel study that weighted back to the initial 12th…

The current study attempts to investigate whether using multiple diagrams attached to a geometry task could reduce difficulties in the proving process regarding concepts in three-dimensional geometry. Ninety 12th-grade students participated in the study. The research included the use of a questionnaire whose items invited open-ended responses…

This study examined the relationship between career interests and career decision-making of grade 12 learners in township secondary schools in South Africa. The correlational survey research design was adopted. The sample size comprised 204 grade 12 learners selected from six township secondary schools. The career interest and career…

Most studies on technology integration in mathematics education are focused on teachers' perceptions or students' academic achievement. However, it is necessary to learn how students perceive their learning in this environment. This basic qualitative study focuses on students' experiences with 1:1 computer-supported collaborative learning (CSCL)…

STEM education has experienced significant growth due to its pivotal role in innovation and economic development. While cognitive factors like prior knowledge are known predictors of STEM success, non-cognitive factors, including attitudes and demographics, also play vital roles. However, there is a notable scarcity of research focusing on the…

One of the critical goals of teaching chemistry is to enable learners to gain conceptual understanding. Traditional instruction has often been associated with rote memorisation, resulting in learners failing to explain observed chemical phenomena, make predictions based on acquired concepts, advance convincing arguments, and engage in meaningful…

Research suggests that students hold misconceptions about the immune system, but little is known about how they reason about the mechanisms by which the immune system operates. This study investigated how students reasoned about the immune system in Beirut, Lebanon. The study used a qualitative approach and investigated 16 Grade 12 participants…

Handwritten tasks are better suited than digital ones to assess higher-order mathematics skills, as students can express themselves more freely. However, maintaining reliability and providing feedback can be challenging when assessing high-stakes, handwritten mathematics exams involving multiple assessors. This paper discusses a new semi-automated…

The aim of this study is to examine how algorithmatizing tasks engage mathematics students in algorithmic thinking. Structured, task-based interviews were conducted with eight Year 12 students as they completed a sequence of algorithmatizing tasks involving maximum flow problems. A deductive-inductive analytical process was used to first classify…

This study evaluates the experimental tasks of the Ethiopian grade 12 chemistry textbook vis-à-vis coverage of the essential components of science process skills (SPSs) using content analysis. All the procedures in an experiment were analyzed using rubrics of the inquiry-based task analysis inventory (ITAI) instrument. This instrument was based on…

In high school geometry, proving theorems and applying them to geometry problems is an expectation for students. An essential part of most geometry proofs is the diagram because it not only helps encapsulate the claim being proved but can also be a tool in reasoning or communicating an argument. This interview-based study investigated how high…

The study investigated how well Swedish adolescents recognize the meaning of derived words in English and whether this knowledge is determined by learner proficiency, word frequency, or affix type. Participants were 88 school students in two proficiency groups: 39 advanced 12th graders and 49 intermediate 9th graders. Two tests of receptive…

Learner-centered instruction fosters 21st-century skills and must be implemented in geography classrooms. In this South African case study, most teachers predominantly implemented teacher-centered instruction. The analysis of the results established a moderate but highly significant relationship between geography teachers' years of teaching and…

Little is known about the motivational factors or design features that might lead female career and technical education (CTE) health sciences students to persist in self-regulated engagement to win state achievement in serious simulation games (SSGs). In this study, 12th grade female CTE health sciences students played a 3-Level hand hygiene SSG…
