A teacher-researcher searched for and defined theoretical principles in the literature that could be used as a basis for teaching high-school students who were struggling in mathematics (in a regular-level mathematics classroom) and could offer a framework to design tasks to encourage a problem-solving, thinking classroom. After identifying 13…

This study explores students' use of mathematical objects in each problem-solving phase based on an onto-semiotic perspective. The subjects of this research are students who solve problems in different ways but all with the correct result. The first student uses organizational data by applying the concept of permutations. In contrast, the second…

Achieving proficiency in fundamental differential calculus concepts remains a persistent challenge for grade 12 students, raising concerns among mathematics teachers and policymakers. Despite the widely acknowledged applications of differential calculus across diverse disciplines, global examination diagnostic reports consistently highlight…

This case study explored Grade 12 learners' misconceptions in limits of functions. The study aimed at understanding problems that learners face in learning the concepts of limit by analyzing misconceptions that learners have and identifying the possible sources of these misconceptions to take remedial action. An exploratory research design was…

The aim of this paper is to explore high school students' critical consciousness development in the context of youth participatory action research (YPAR) focused on food security at an alternative school in Alabama. The YPAR project took place in an elective agriscience class with 10 students (Seven Black, two white, one Latino) who were in the…

Many students in schools may demonstrate problem behaviors and show signs of academic disengagement behaviors in schools, especially students who are educated in upper-secondary schools. Exhibition of problem behaviors may negatively affect students' academic performance. These students need to receive effective interventions, such as behavioral…

This quantitative study examined Lebanese secondary school students' attitudes toward socio-scientific issues (SSIs), focusing on climate change as a representative topic due to its social, economic, and political complexities. A sample of 130 students from grades 10 to 12 in Lebanese private schools completed the Attitudes Toward Socio-scientific…

In this paper, we finish describing the project and the experimentation of "Ricerca Operativa Applicazioni Reali" (ROAR; in English, Real Applications of Operations Research), a three-year project for higher secondary schools. ROAR is composed of three teaching units addressed to grades 10, 11, and 12, respectively. To improve students'…

This study aimed to provide a deeper understanding of high school students' errors while solving genetics problems. Four students were asked to solve two genetics problems and participate in a modified think-aloud interview. Data from the interview, video clips of the problem-solving process, and test sheets were used to analyse participants'…

There exists a gap in the literature that discusses the issue of those who teach STEM degree courses who have not been given appropriate training to effectively integrate and implement analytical problem-solving skills (APSS) within their curriculum. At the center of this research is the need for effective training of implementing analytical…

This research aimed to reveal the effectiveness of using a Problem-Based Learning (PBL) physics pocketbook integrating augmented reality (AR) with the local wisdom of catapults in improving the mathematical and graphical representation abilities of high school students. This study is a quasi-experiment with a pretest-posttest control group design.…

This study was guided by the question, how do we understand the multiplicative reasoning of upper high school students and use that to give insight to their performance on a standardized test? After administering a partial ACT assessment to a class of high school students, we identified students to make comparisons between low and high scoring…

Class size is an essential factor in student academic achievement. Small class sizes improve student achievement and teacher morale. For this reason, the researchers of this study set out to determine the relationship between class size and academic achievement among students with learning difficulties in secondary schools in Kakamega County,…

Euclidean geometry provides an opportunity for learners to learn argumentation and develop inductive and deductive reasoning. Despite the significance of Euclidean geometry for developing these skills, learner performance in mathematics, particularly geometry, remains a concern in many countries. Thus, the current study examined the nature of…

Self-knowledge is an important element of metacognition. It encompasses understanding one's own strengths and weaknesses and includes belief and self-assessment of one's capacity to perform a task. Cognitive skills comprise a range of mental processes, such as attention, memory, problem solving, systems thinking, abstract thinking, and critical…
