Abstract

In learning geometry, the discussion about the definition of quadrilateral is a material that is difficult and not easily taught by the teacher. This study aims to explore the teacher's specialized content knowledge about square. This is a descriptive-qualitative research. The process of selecting subjects begins with searching prospective subject data according to the level of the teacher through a portfolio of 82 teachers in South East of Sulawesi: (33 First Teachers, 33 Young Teachers, and 16 Intermediate Teachers). The research subjects consisted of three teachers, namely: First Teacher, Young Teacher dan Intermediate Teacher with score > 50. Data were taken using vignette. The results show that there is a difference when the teacher is asked to define a square with when given a definition of a square. First Teacher is accurate when given a square definition with the symmetry and diagonal axis attributes; the side attribute is not accurate in giving arguments to the square definition. Young Teacher is inaccurate when given the definition of a square with side and angle attributes; accurate with symmetry and diagonal axis attributes; but it is not accurate when given a square definition. Regarding attributes of side; Intermediate Teacher revealed that the side and angle attributes are inaccurate but accurate with the symmetry and diagonal axis attributes but do not appear / are not used when asked to define a square. Specialized content knowledge First Teacher is better because it has been able to reconstruct concepts from a square, but Young Teacher and Intermediate Teacher are still influenced by concept images and figural concepts.

Abstract

The purpose of this research is to develop a valid, practical and effective junior high school mathematics worksheet. Local wisdom referred to in this study is a traditional food, namely Jagung Bose, Jagung Katemak, Ut Kono, and Laku Tobe, which have become a daily diet for the people of the Indonesia-Timor Leste border community on the Pulau Timor. This research is a kind of development research using the Tessmer formative evaluation model, which consists of two stages of development, namely the preliminary analysis stage and the formative evaluation stage. The subject of this research is the 9th-grade students of Taloeb Junior High School in the border area in 2020. The data collection techniques used include tests, learning outcomes, observation, and interviews. Experts have validated the development of student worksheets using the context of local traditional food wisdom with the results of assessments from material experts, media experts and linguists. Validated by Experts, Students Worksheets (SW) of maths included in the very good category and trial results have shown that the SW meets the practical criteria and has a potential effect on improving junior high school students' mathematics skills and learning outcomes.

Abstract

This study aims to find out how teachers diagnose to determine students’ learning difficulties, especially in Mathematics in Elementary Schools. There are four aspects discussed in this study, including the teachers’ perception of students’ learning difficulties, teachers’ practice in connection with diagnosing students’ learning difficulties, teachers’ actions in response to the results of the diagnosis, parties involved regarding students’ learning difficulties. The research method used was descriptive qualitative with 13 teachers as the subject selected by purposive sampling. The data were obtained through interviews with classroom teachers, both from private and public schools, especially in North Borneo. The findings in this study show that the teachers use various ways to diagnose and overcome students’ learning difficulties. There are 3 ways that teachers do to diagnose learning difficulties in Mathematics, including tests, observations and interviews. While the ways to overcome them are to do remedial, provide tutoring individually, provide additional hours for students who have learning difficulties in Mathematics and involve students in learning. The method used has been effective, proofed by changes in students’ understanding and improvement in students’ learning outcomes. This study offers elementary school teachers ways that can be carried out to diagnose and overcome students’ learning difficulties in Mathematics.

Abstract

There are many difficulties that can be identified when students solve mathematic problems especially in solving probability word problems. This study was conducted to identify the major obstacles faced by matriculation college students while solving the probability of an event word problems. Seven college students were the sample for this case study. Clinical interviews are used as a data collection. This data collection technique was selected based on the researcher’s observation on the participants as they answered the probability word problem task. The task was given during the interview session. Semi structured interviews are used to obtain in depth information. Think-aloud analysis involves observations leading to individual behaviours in the oral or nonverbal form of participants and the researcher’s field notes. Participants were found to have difficulty interpreting probabilities. There are three categories of difficulties that have been identified, namely not knowing the meaning of the word, not knowing the nature of the probability and not being able to identify the goal of the probability word problem.
