Abstract

Statistical literacy is a key ability expected of citizens in information-laden societies, and is often touted as an expected outcome of schooling and as a necessary component of students' numeracy and literacy. The facts show that the statistical literacy ability of Indonesian students is still in an alarming category and Indonesian students for junior high school have not been able to compete internationally in the statistical literacy. This qualitative descriptive research was conducted to describe junior high school students’ ability and difficulties in basic skills of statistical literacy. Data were collected from 6 students of 8th grade in one of junior high school in Aceh, Indonesia through test and interviews. The results clearly show that students’ statistical literacy are still in low category. Students are good in understanding the data but they have limited understanding of the data presentation concept. Students have difficulty in using the principle of presenting the data into the pie chart. Many steps of presenting the data are not complete. From this study can be concluded that students’ basic skills of statisical literacy has not been satisfied. Therefore, mathematics learning process in data presentation concept should be improved.

Abstract

This study examines the effect of the inquiry learning model on the mathematical problem solving ability of students in Indonesia through meta-analysis. This study analyzed seven primary studies that met the inclusion criteria. The effect size index was calculated using the Hedges g equation and statistical analysis using comprehensive meta-analysis (CMA) software. Effect size testing is done by analyzing four characteristics, namely class of study, year of study, and sample size. Based on the results of the analysis using CMA, the inquiry learning model has a moderate effect (0.652) on the overall mathematical problem-solving skills of students. The use of the inquiry learning model is more effectively used in 8th-grade, in the range of 2015-2017 and 2018-2020, the sample size is less than or equal to 30. Thus, it can be seen that the inquiry learning model is useful in improving mathematical problem-solving skills.

Abstract

Metakognisi adalah suatu tingkatan dalam proses berpikir yang dapat digunakan siswa untuk memecahkan masalah, memiliki kesadaran terhadap proses berpikirnya dan mengontrol cara berpikirnya. Pada pembelajaran matematika di sekolah kita sering menemukan banyak siswa yang mengalami kesulitan dalam memecahkan masalah disebabkan  kurangnya kesadaran dan control dalam diri mereka. Kesulitan ini pun terjadi pada siswa kategori cerdas istimewa yang memiliki IQ di atas 130. Pada penelitian ini, peneliti ingin melihat bagaimana kemampuan yang dimiliki oleh siswa cerdas istimewa dalam memecahkan masalah matematika. Penelitian ini menggunakan metode kualitatif deskriptif. Penelitian ini dilakukan di sebuah SMP di kota Bandung dengan sample sebanyak 13 orang siswa cerdas istimewa. Untuk mengukur kemampuan metakognisi, siswa diberikan soal pemecahan masalah beserta angket metakognisi. Dari hasil penilaian pemecahan masalah, siswa cerdas istimewa memperoleh nilai rata – rata sebesar 59. Secara rinci, kemampuan metakognisi siswa cerdas istimewa berdasarkan angket yang mereka isi berada pada kriteria cukup baik untuk tahap planning, monitoring dan evaluating yaitu berada di kisaran 41% - 60%, dengan presentase berturut – turut 58,46%, 52,56% 53, 64%. turut 58,46%, 52, 56% 53, 64%. Metacognition is a level in the thinking process that students can use to solve problems, have awareness of their thinking processes, and control the way they think. In learning mathematics in schools, we often find many students who have difficulty solving problems due to a lack of awareness and control within themselves. This difficulty also occurs in the special intelligent category students who have an IQ above 130. In this study, the researcher wanted to see how the abilities possessed by special intelligent students in solving mathematical problems. This research is a descriptive qualitative method. This research was conducted in a junior high school in Bandung with a sample of 13 special intelligent students. To measure metacognitive ability, students are given problem-solving questions along with a metacognition questionnaire. From the results of the problem-solving assessment, the special intelligent students got an average score of 59. In detail, the metacognitive abilities of the special intelligent students based on the questionnaires they filled were in the good criteria for the planning, monitoring, and evaluating stages, which were in the range of 41% - 60 %, with a successive percentage of 58.46%, 52.56% 53,4%.
