Abstract

Participation is an important factor in achieving maximum learning in achieving learning goals. However, the level of student participation in learning is still relatively low. Therefore, efforts need to be made in the form of innovation in learning to increase student participation in learning, such as implementing LSLC based on the Jigsaw learning model. This research is a descriptive study with a sample of class XI IPS 1 SMA Adabiah 2 Padang. This research aims to see the impact of LSLC on student participation in learning using the Jigsaw learning model. Based on the results of data analysis, it was found that for each meeting there was a significant increase in student participation. So it can be concluded that learning using LSLC and the Jigsaw learning model has a positive impact on student participation in learning.

Abstract

This research includes ex post facto correlation research, which aims to determine the correlation of the independent (free) variable, namely Indonesian Language Literacy (X), with the dependent variable (tied), namely Mathematical Numerical Literacy (Y). The research was conducted in the January-June 2023 semester in 1 class VIII containing 30 students at a junior high school in Padang. Data was collected by testing one-story test questions. The sampling technique is purposive sampling. Data were analyzed using the Spearman Rank Correlation using the Kolmogorov-Smirnov normality test and hypothesis testing. The correlation coefficient value of Indonesian language literacy with the mathematical numeracy literacy variable is "positive 0.953". So that the relationship/correlation of the two variables is categorized as significant, vital, and in the same direction, this can be interpreted that if the Indonesian language literacy of class VIII students in the sample increases, the numeracy literacy of students in solving math problems will also increase, and vice versa. Penelitian ini termasuk penelitian korelasi expost facto yang bertujuan mengetahui korelasi  variabel independen (bebas) yaitu Literasi Bahasa Indonesia (X) dengan variabel dependen (terikat) yaitu Literasi Numerasi Matematika (Y). Penelitian dilakukan semester Januari-Juni 2023 pada 1 kelas VIII berisi 30 siswa pada suatu SMP di kota Padang. Dikumpulkan data dengan mengujikan 1 soal tes cerita. Teknik pengambilan sampelnya purposive sampling. Data dianalisis dengan uji normalitas Kolmogorov Smirnov dan uji hipotesis menggunakan Korelasi Spearman Rank. Nilai koefisien korelasi literasi bahasa Indonesia dengan variabel literasi numerasi matematika bernilai “positif 0,953”. Sehingga hubungan/korelasi kedua variabel tersebut dikategorikan signifikan, kuat, dan searah. Hal ini dapat diartikan bahwa jika literasi bahasa Indonesia siswa kelas VIII pada sampel semakin meningkat maka literasi numerasi matematika siswa dalam menyelesaikan soal matematika juga akan semakin meningkat, begitu pula sebaliknya.

Abstract

Critical thinking skills are one of the important competencies of the 21st century that need to be developed through mathematics learning, especially in flat geometry, namely circles. One important indicator of critical thinking is analytical skills, namely the ability to analyze information, identify relationships between concepts, and draw rational conclusions. This study aims to describe students' mathematical critical thinking skills in the indicator of analysis in circles. The research used a descriptive quantitative approach with a sample of 31 eighth-grade students at a public junior high school in Padang City. The instrument consisted of one essay question that asked students to analyze two different arguments related to the concepts of diameter and chord, choose the correct argument, and provide logical reasons based on the concept of circles. Scoring was done using an analytical rubric with a score range of 0–5. The results showed that only 3.22% of students were able to analyze correctly with logical reasoning, 6.45% of students could choose the correct argument but without a conceptual explanation, 80.65% of students were unable to analyze correctly and tended to copy the arguments in the questions, and 9.68% of students did not provide answers. These findings indicate that students' mathematical critical thinking skills, particularly their ability to analyze circle-related material, are still low. This study emphasizes the importance of mastering basic concepts as a foundation for promoting critical analysis skills in mathematical problem solving.
