Abstract

Maths is one of the most challenging courses for many pupils. Maths is often the most complex subject for many students. Newman's Error Analysis analyses eighth-graders math problems. Assessing higher-order cognitive ability is the primary purpose. This qualitative study was conducted in a Majalengka, West Java, junior high. Five randomly selected kids with different math skills participated. Following up with interviews and testing Bloom's taxonomy's latest HOTS signal questions were the critical data collection approaches. These questions test analytical (C4), evaluative (C5), and creative (C6) skills. Students had to model, sketch, confirm geometric calculations, and calculate dimensions using available components. Newman's Error Analysis was applied to analyse typical misunderstandings and errors. This exercise showed students' geometric reasoning and problem-solving weaknesses. The findings suggest customised teaching methods to improve students' geometric knowledge and performance. Reducing data, presenting facts, and concluding helped us comprehend pupils' cognitive processes and geometric challenges.

Abstract

This research aims to describe the difficulties experienced by students in solving mathematics story problems on opportunity material. The type of research used is a descriptive method with a qualitative approach. The study involved 30 students in class XII IPS 2 SMA Negeri 2 in Pekanbaru. Data were collected using a combination of tests and interviews. The overall research procedure involved three stages, namely the planning stage, implementation stage, and conclusions. Data were analysed using descriptive statistics. The results of this study show that students’ experienced difficulties in solving mathematics story problems on opportunity material especially in understanding the problem (33,33%), carrying out transformations (36,66%), processing skills (38,88%), and difficulty in drawing conclusions (51,11%).

Abstract

Multiple-choice questions (MCQs) are highly used in assessing students’ learning outcomes due to their versatility in promoting test content validity. Nevertheless, teachers experience psychometric challenges in constructing quality MCQs. This study investigated primary school teachers’ competence in constructing quality MCQs in Dar es Salaam Region, Tanzania. Specifically, we examined teachers’ competence in constructing quality MCQs, analyzed the types of item-writing flaws (IWFs) found in teacher-made MCQs, and examined the challenges that teachers encounter in constructing quality MCQs. The study was guided the by classical test theory (CTT) and it employed a mixed-method research approach. In particular, data collection and analysis were conducted using a concurrent triangulation design. A total of 213 MCQs constructed by 20 teachers from ten primary schools were collected and analyzed. The results indicated that primary school teachers were less competent in constructing quality MCQs as 156 (73.2%) of the teacher-made MCQs assessed lower levels of Bloom’s cognitive domain. Similarly, most of the MCQs had IWFs, with 274 (69.2%) having test wiseness flaws and 122 (30.8%) having irrelevant difficulty flaws. The findings call for capacity building to promote teachers’ competence in constructing quality test items.

Abstract

Homework is a crucial formative assessment tool that helps to keep students engaged on tasks beyond school hours. This study investigated students’ perceptions of teacher support on homework tasks during school breaks. Specifically, it focused on how students perceived the mathematics teachers’ support in terms of task quality, feedback quality, and promoting mathematics autonomy. The study also focused on how these perceptions varied by gender and school ownership type, and how they related to students’ self-efficacy in mathematics. It was carried out in Dar es Salaam, Tanzania, and involved a random sample of 579 students from six primary schools. Previously validated questionnaire scales were adapted for data collection. The data were analysed by using descriptive statistics, latent mean analyses, and structural equation modelling techniques. Results from the descriptive statistics indicated that students positively evaluated teacher support in homework. Besides, student perceptions did not significantly differ across genders but differed between school ownership. The findings indicate a significant relationship between students’ perceptions of teacher support and their mathematics self-efficacy. The findings call for the effective utilisation of homework to augment classroom instructions.
