Abstract

The 2022 Education Report reveals that high school-equivalent students scored 50.74% in numeracy literacy, below the minimum competency. Emphasizing mathematical literacy is crucial, yet such problems are scarce in classrooms. The research aims to develop mathematical literacy questions. The trigonometry material was chosen for the reason that this material should enable literacy activities related to material concepts. Following the ADDIE (Analysis, Design, Implementation, and Evaluation) model, the study employs expert validation and student responses as instruments, involving 20 students in small and large-scale test phases. It yields four trigonometry essay questions for high school. The research results show that the Mathematical Literacy test developed has quite valid categories in terms of content, construct and language. The questions are declared reliable. All types of questions are difficult. Discrimination index of questions, 1 question in the average category, and 3 questions in the low category. The developed questions are in the difficult category because at the mathematical literacy level, the abilities that are developed are not at the level of low-level thinking. This research supports efforts to increase student competency in mathematical literacy at the high school level.

Abstract

The pandemic has profoundly impacted education, posing unprecedented challenges that demand immediate attention. Thus, this study was conducted to identify intervention activities that may be introduced on the learning gaps in Integrated Mathematics 9 for the First Quarter of the School Year 2022-2023. A quantitative quasi-experimental research using a pretest-posttest design was employed in this study and conducted on the 31 Grade 9 students of St. Paul University Surigao during the First Quarter of the School Year 2022-2023. A validated test was used to conduct the pretest and posttest to assess the learning gaps in Mathematics 9. Frequency, percentage distribution, and paired t-test were used in analyzing the data gathered. This study found that there are least-mastered competencies in the First Quarter of Mathematics 9. In addition, there is a significant difference in the pre-and posttest performance of the learners, especially after giving intervention activities such as drill, practice exercises, tutoring sessions, or small group instruction, peer tutoring and collaborative learning, expanded opportunity, explicit and technology-assisted instruction. Thus, the intervention improved learner performance and addressed least-mastered competencies. It is recommended for mathematics teachers to design further intervention materials targeting other least-learned competencies.

Abstract

Teachers and students have different ideas and expectations about the didactical situation that evolves in the classroom. It needs rules that determine teachers’ and students’ unique responsibilities relating to the didactical situation or contract. The division of roles and responsibilities moves from the teacher as the centre to the students as the centre. The results of a case study design of 42 students showed that the transition from ostentation to Mayeutic Socrate and then to the adidactical contracts was smooth and progressive if the teacher and the participants cooperated and actively participated in the milieu. It was therefore recommended that teachers streamline method-friendly guidelines, strategies, and techniques at the ostentation contract for students to emulate, students cooperate and support the teacher at the mayeutic Socratic contract and the knowledge of both local indigenous and exotic artifacts must complement each other at the adidactical contract.

A quasi-experimental design with experimental and control groups, including pre-test, post-test, and post-posttest measures, was implemented. The target population consisted of 1329 JSS II Students from Bida Local Government Area, Niger State, with sample size of 171 (Male=84, Female=87) students from two schools and two intact classes. Sample was determined through purposive and simple random sampling, selecting all mixed schools with experimental and control groups. Three research questions and hypotheses were formulated to guide the study. Data collected employed instruments: The Geometry Performance Test (GPT), Geometry Achievement Test (GAT), Lesson model for the control and experimental group. The GPT and GAT were validated by three experts and also demonstrated good reliability. The results revealed that students taught with instructional material performed better comparing with those taught without instructional materials and also there is no significant differences found in gender in the experiment group. In addition, there is significant difference in the retention ability of those who were taught using instructional materials and those taught without instructional material. Based on these results, mathematics teachers should use instructional materials during teach mathematics especially geometrical shapes.
