Abstract

This research explores students' mathematical communication skills in solving Higher Order Thinking Skill (HOTS) problems, considering visual, auditory, and kinesthetic learning styles. The study aims to describe students' mathematical communication abilities and understand how learning styles influence these capabilities. A qualitative descriptive research method was employed, involving second-semester seventh-grade students at MTs Negeri 1 Pacitan. Data collection comprised learning style questionnaires, mathematical communication skills tests, and interviews. Results indicate that students with visual learning styles effectively conveyed situations and explained problem-solving strategies but lacked precision in validating arguments. Auditory learners demonstrated proficiency in all four indicators of mathematical communication skills, including argument validation. Kinesthetic learners, while capable of stating situations, encountered difficulties in elucidating problem-solving strategies and did not engage in argument validation.

Abstract

Online and e-learning programmes have shifted the power bloc to the learner within their cultural settings. In a case study-based qualitative design, the researchers sampled 40 student-teachers to produce and laminate works of prominent women scientists’ contributions. The data was collected through observations and unstructured interviews. The items were coded on four 7-point Likert scales to represent the planning and design (satisfaction), teaching and learning (reflection), as and through learning (priority), formative assessment (quality), and assessment of virtual class (satisfaction). In qualitative content analysis, the medians predominantly pooled 6 while the modes pooled between 5 and 8 (multimodal). In cases where the median was greater than the mode, we had positive skewness and the reverse was negative skewness. The Spearman’s correlation coefficients showed that only one pair recorded strong positive correlation and two to three pairs recorded strong negative correlations. The chi-square tests for independence showed the null hypothesis was rejected to mean that there were associations among the variables. It was concluded that digital didactics was the central point for the design and use of teaching and learning. It was therefore concluded that digital didactics innovated mathematics instruction and learning.

Abstract

This study explores using Python to solve Bernoulli’s equations with the goal of enhancing student understanding. Inquiry-Based Learning (IBL) is integrated into it. The research included second-year students majoring in mathematics from Srinakharinwirot University. The teaching approach began with an introduction to Bernoulli’s equations in theory. These equations were then converted into linear form and solved using Python programming. Among the practical tasks in which students took part were post-test assessments, group problem-solving, and pre-test evaluations. Group members used Bernoulli’s equations to real-world scientific problems including fluid mechanics and population dynamics using Python to generate solutions and present discoveries. Inquiry-based learning (IBL) principles were used in the study, where students posed questions, looked into problems, and assessed the solutions using Python. The results demonstrated a greater understanding of mathematical concepts as well as computational techniques. The decrease in standard deviation between the pre- and post-test data showed how well IBL and Python combine to foster critical thinking and practical problem-solving skills. This method has the potential to assist student teachers acquire computational abilities and a deeper understanding of mathematics, which will better prepare them for careers as teachers.
