Abstract

This study investigates opportunities for enhancing the secondary school mathematics curriculum in South Africa. Employing a cross-sectional survey design, data were collected from a purposive sample of 80 postsecondary students enrolled at higher education institutions across the country. An online questionnaire was administered, and responses were analyzed using the Statistical Package for the Social Sciences (SPSS), focusing on frequency distributions and mean ranks. The findings reveal that while the current mathematics curriculum adequately prepares some students for postsecondary studies, it falls short for others. Key areas identified for improvement include better alignment with tertiary-level mathematics, reforming examination formats, enhancing pedagogical approaches, and increasing collaboration with local industries. Based on these insights, the study proposes several recommendations: offering specialized mathematics tracks, including optional exam questions, reducing exam length, introducing calculus prior to Grade 12, integrating digital tools in instruction, and connecting mathematical learning with real-world industry applications. By foregrounding students’ perspectives, this research promotes a bottom-up approach to curriculum development. The study contributes to the literature by providing empirical evidence on curriculum gaps from the learner’s viewpoint and offering context-specific recommendations to bridge secondary and tertiary mathematics education in South Africa.

Abstract

This study investigates the impact of the Alef educational platform on student learning outcomes in the topic of conic sections, focusing on both academic performance and student perceptions. The research involved a purposive sample of 64 Grade 11 advanced mathematics students from a high school in Fujairah, United Arab Emirates. A quasi-experimental design was employed, incorporating pre-test and post-test assessments. Data were collected through a researcher-developed test and an online Likert-scale survey. The findings indicate that the Alef platform significantly enhances students’ understanding of conic sections by personalizing instruction to meet individual needs and by using interactive media to present multiple representations of mathematical concepts. This approach caters to diverse learning styles and promotes deeper engagement. Moreover, students reported being able to recall key lesson ideas effectively and felt comfortable participating in class without fear of ridicule. They expressed enjoyment in learning conic sections through the Alef platform and expressed a desire for its broader integration across mathematics lessons. Overall, the Alef platform positively influenced students’ perceptions of mathematics. The study highlights the value of integrating technology into mathematics education to create a more inclusive and effective learning environment. This study contributes to mathematics education by providing empirical support for the use of technology-enhanced, student-centered learning environments—grounded in constructivist and self-determination theories—to improve conceptual understanding and motivation in specific mathematical topics.
