Abstract

Number sense is a skill that contributes significantly to learning mathematics. However, number sense is often positioned as a fundamental skill whose development is more focused on children. The contribution of number sense in mathematics is even more apparent at higher levels of education. Ironically, number sense seems ignored and has become a rarely studied topic in higher education. Thus, the student's number sense ability profile seems buried with various problems. This study aims to reveal the profile of prospective elementary school teachers' number sense abilities and the factors causing their failure in solving math problems during the implementation of blended learning. This study uses a qualitative approach with 37 prospective elementary school teachers as research subjects. The observation of the test and lecture activities is the data collection method. The results showed that the prospective elementary school teachers' number sense ability was still relatively low. Based on the components, the order of number sense abilities is from the highest, namely: (1) knowledge and number facilities with the achievement of 14.41%; (2) knowledge and facilities for number operations with the achievement of 8.12%; and (3) knowledge and facilities of numbers and operations for computing settings with an achievement of 1.8%. The low number sense ability is caused by the habit of solving problems procedurally and the failure to solve problems due to misconceptions, not understanding concepts, inaccuracy, inability to understand questions, and difficulty representing fractions. Various factors causing the failure arose due to the limitations of implementing blended learning.

Abstract

The purpose of this study was to improve science learning achievement using the Think Pairs Share (TPS) learning model for class IV at SD N Tirtosari. This study uses PTK method. Data collection techniques with interviews, observations, field notes, and tests. Sources of data are teachers and students as research subjects. The data analysis technique is descriptively taken from the average achievement score and the percentage of student completeness. Based on the research, it was concluded that the use of the TPS learning model could improve the learning achievement of fourth grade students at SD N Tirtosari. In the pre-action the average student achievement was 69.28 with a completeness percentage of 42.85%, in cycle I it increased from 5.86 to 75.14 with a completeness percentage of 57.14% because it was not in accordance with the percentage of success then proceed to cycle II . In cycle II there was an average increase of 11.71 so that the average student achievement was 86.85 with a completeness percentage of 100%. From this description it can be seen that there has been an increase from the pre-action stage, cycle I to cycle II.

Abstract

Urgensi penelitian ini didasarkan pada tuntutan Pendidikan abad ke-21 yang menempatkan kemampuan berpikir kritis sebagai kompetensi esensial, khususnya dalam pembelajaran matematika yang berperan penting dalam melatih penalaran dan pemecahan masalah. Namun, praktik pembelajaran di sekolah dasar masih cenderung berpusat pada guru dan kurang memberi ruang bagi siswa untuk mengembangkan kemampuan berpikir tingkat tinggi. Kondisi ini menegaskan pentingnya penerapan model pembelajaran yang lebih aktif dan kolaboratif, seperti pembelajaran kooperatif tipe Numbered Head Together (NHT), guna mengoptimalkan kemampuan berpikir kritis siswa. Penelitian ini bertujuan untuk mengetahui bagaimana strategi pembelajaran kooperatif Numbered Head Together (NHT) memengaruhi kemampuan berpikir kritis siswa kelas IV SD Muhammadiyah Integratif Dukun pada tahun ajaran 2024–2025. Penelitian ini penting dilakukan mengingat kemampuan berpikir kritis merupakan kompetensi esensial abad ke-21, sementara praktik pembelajaran di sekolah dasar masih cenderung berpusat pada guru sehingga kurang mengoptimalkan pengembangan kemampuan berpikir tingkat tinggi siswa. Sebanyak 48 siswa berpartisipasi dalam penelitian ini, dengan menggunakan desain kuasi-eksperimental dengan kelompok kontrol non-ekuivalen. Instrument penelitian berupa tes kemampuan berpikir kritis matematika dalam bentuk soal uraian yang telah melalui uji validitas dan reabilitas. Pengumpulan data dilakukan melalui pemberian pretest dan posttest pada kelas eksperimen dan kelas kontrol. Uji normalitas Shapiro-Wilk, uji homogenitas Levene, dan uji t sampel independen digunakan untuk menganalisis data menggunakan SPSS 27 pada tingkat signifikansi 0,05. Berdasarkan hasil analisis, diperoleh nilai Sig. pretest sebesar 0,079 (>0,05) dan nilai Sig. posttest sebesar 0,007 (<0,05). Skor rata-rata posttest kelas eksperimen adalah 80, yang lebih tinggi daripada skor kelompok kontrol yaitu 70. Oleh karena itu, teknik pembelajaran kooperatif NHT mendorong pertumbuhan kemampuan berpikir kritis matematika siswa.
