An Exploration of Topic-wise Mastery in Mathematics and its Relationship with Students’ Motivation, Perception, and Interest.
type: item
description: This study investigates the heterogeneity of topic-wise mastery in mathematics and its relationship with affective factors among Malaysian secondary school students. Despite documented national weaknesses in international assessments such as PISA (PISA 2022 Results (Volume I), 2023) it remains unclear which specific curriculum topics pose the greatest challenges. Using a quantitative design, the achievement of 50 Form 2 students was assessed across five core mathematical domains: Algebra, Geometry, Statistics, Probability, and Straight Lines. Affective factors, including Motivation, Perception, and Interest, were measured via a survey questionnaire. Repeated Measures ANOVA revealed a highly significant main effect of topic on student achievement (p < 9.255×10⁻³¹). Multiple Linear Regression (MLR) analysis indicated that affective factors were not statistically significant predictors of achievement for any individual topic. These findings highlight the necessity of a topic-wise diagnostic approach and suggest that extrinsic, structural factors, such as instructional quality, are the dominant influences on topic-wise success, calling for targeted pedagogical interventions in abstract domains.

type: item
description: STEM education is important for the twenty-first-century student, and there are several challenges that educators face when it comes to implementing it. One of the greatest challenges in implementing STEM education in schools is addressing the misconceptions and stereotypes that surround these subjects. Some people, even teachers, believe that STEM subjects are too difficult or only suitable for certain students. This can create barriers to participation and discourage students from pursuing their interests in these fields. Theory based on Social Constructivism is the central pillar in the discussion of this article, and it focuses on the Asking Phase in Engineering Design Process (EDP). Students are required to identify the needs and constraints when university students apply the Asking Phase in one of the Engineering Design Process in a parachute activity with the title Landing to the Moon. There are four questions involved namely, how does students discuss on the main goal of the activity, resources that they have, needs or challenges to be considered, and the available resources that can overcome the challenges and achieve their goals. A case study has been designed and the method of selecting respondents is through cluster sampling, which is to choose seven groups of Science Education students at public universities in Selangor. The results of the study showed that four (4) aspects of achievement are required for the goal of the project, three (3) main resources were chosen to start the project, eight (8) challenges need to be considered, and nine (9) ways to overcome the challenges and to ultimately achieve the project.

type: item
description: Two organic chalcone compounds, both featuring a donor-pi-acceptor (D-π-A) configuration, specifically (E)-1-(4-nitrophenyl)-3-(4-phenylthiophen-2-yl)prop-2-en-1-one (Ch1) & (E)-4-(3-(4-phenylthiophen-2-yl) acryloyl)benzonitrile (Ch2) were meticulously designed and synthesized using the Claisen-Schmidt condensation reaction method. The resulting compounds were purified by repeated recrystallization in acetone solvent and single crystals were grown via a slow evaporation solution growth technique. This research centers on the computational modeling of these two chalcone compounds, employing Density Functional Theory (DFT). Molecular geometry, including bond lengths and bond angles, was determined from the DFT-optimized structures using the method B3LYP/6-311 G++(d,p) basis set in the ground state. Notably, the HOMO-LUMO energy gap, falling within the 3.1 to 3.4 eV range, indicates these compounds' suitability for facilitating efficient charge transfer. As a result, these specifically designed and computed materials hold great promise for potential use in optoelectronic devices due to their small energy gaps.
