2023-05-24T16:07:52+00:00

Pedagogical Content Knowledge (PCK) tasks and decision-making are closely related to teaching and learning mathematics. This study aims to investigate teacher PCK in decision-making on different algebra tasks and to see activity in teacher-student interactions. This research is qualitative, with a research approach used as a case study. The participants in this study were only one teacher with different characteristics in mathematics tasks. Data collection consisted of primary research data from class observations, teacher interview transcripts, and researcher notes, while documents such as teacher notes were secondary data. Data analysis was carried out directly based on class observations and interviews. The findings in this study reveal teacher PCK through teacher decision-making regarding algebraic tasks in Swartz & Perkins (2016) three theories of thinking: generating ideas, clarifying ideas, and assessing the reasonableness of ideas.

The descriptive study analyzed the skills of vocational school students with low, medium, and high levels of mathematical anxiety in terms of their problem-solving abilities. It used a qualitative approach to examine the various mathematical content strands and scientific contexts of the learners. Its findings were based on the notion of the problem-solving stage by Polya, Newman, as well as Krulik and Rudnik. The data collected during the study was gathered through a written test, which involved asking the participants to complete a questionnaire about their mathematical anxiety levels before they were asked to solve numeracy problems. The results of the study revealed that students with high levels of anxiety were more prone to experiencing problems with problem-solving. The findings of this study are valuable to mathematics educators and researchers. It is also expected to contribute to the development of effective problem-solving strategies for students.

The use of mathematics learning media in the lower class is necessary because low-class students are not yet able to think abstractly, which is a need for visualization in reals form. The purpose of this study was to improve student learning outcomes in addition to calculation operations with the help of counting board media. The development model used is the ADDIE model, with the sample being 20 students in grade 1. Data collection techniques used questionnaires, interviews, observations, tests, and documentation. The results of this validation related to the feasibility of design experts amounting to 88.33% including a very feasible category, material experts amounting to 84.17% including a feasible category, and learning experts amounting to 92.5% including a very feasible category. Then the results of the field trial obtained an N-Gain value of 0.73 which is included in the high category. So that the development of the counting board media can improve student learning outcomes in addition to operation material for MINU Unggulan Wali Songo Bojonegoro students.

This study aims to determine the mathematics teacher's perception and its effect on literacy numeracy in high school. This research is descriptive qualitative. The population in this study were high school mathematics teachers. The sampling technique used is total sampling. A total of 30 teachers were sample correspondents spread across several high schools in Malang City. The data collection technique used was a questionnaire consisting of multiple choice, complex multiple-choice, and questions with yes or no answers, which aim to determine the mathematics teachers’ perception of literacy numeracy and its effect on learning in high school. Techniques for presenting data in descriptive statistics include tables and percentage calculations. The study’s results on the perception of mathematics teachers on literacy numeracy in high school showed an average of 67.58% with a positive interpretation level. Also, the effect of mathematics teachers' perceptions of literacy numeracy on learning in high school shows an overall average of 75.6% with a positive interpretation level.

Analisis Kebutuhan Pengembangan Instrumen Penilaian Kemampuan Berpikir Geometri Berbasis Website

The ability to think geometrically is hierarchical so students need to master the initial level of thinking before they are going to the next level. Geometry learning strategies need to consider the level of students' thinking abilities. Assessment with paper-based tests has weaknesses in terms of practicality and does not develop students' technological literacy in the digitalization era. This study aims to analyze the need for the development of a website-based instrument to assess the geometric thinking skills of elementary school students referring to Van Hiele's theory. This research is a literature review with a qualitative approach. The articles reviewed in this research are articles that discuss thinking skills based on Van Hiele's theory with research subjects of elementary school students and published from 2021 to 2023. Data were analyzed by Miles and Huberman's interactive model. The results showed that a web-based instrument for assessing the geometric thinking abilities of elementary school students based on Van Hiele's theory was needed to systematically assess students' geometric thinking abilities then could be followed up with learning activities according to students' abilities. The level of thinking of elementary school students assessed is from visualization to abstraction which is adapted to the material and curriculum of the elementary school.
