Abstract

Studi literatur ini mengkaji arah dan trend penelitian pendidikan matematika sejalan dengan trend dan temuan baru dalam pendidikan matematika. Topik penelitian pendidikan matematika masa lalu didominasi oleh NCTM dengan fokus ke siswa pendidikan dasar sebagai subjek penelitian. Saat ini topik penelitian pendidikan matematika mengkaji ke arah proses berpikir tingkat tinggi siswa dengan subjek yang merata. Penelitian pendidikan matematika ke depan juga akan mengkaji kemampuan berpikir tingkat tinggi yang lebih ditekankan pada kemampuan 4C (creativity, crictical thinking, communication, collaboration). Adanya pandemi covid-19 dan juga penerapan kurikulum kampus merdeka dan merdeka belajar akan berdampak terhadap pendidikan matematika.

Abstract

Penelitian ini bertujuan untuk mengetahui apakah ada pengaruh pembelajaran dengan model kooperatif tipe Student Team Achievement Divisions (STAD) terhadap kemampuan pemahaman konsep matematis peserta didik pada Materi SPLDV kelas VIII SMP Swasta Free Methodist 1 Medan. Dari hasil perhitungan analisis regresi diperoleh persamaan regresi untuk kemampuan komunikasi matematis: Y=-1,65+1,05 X . Untuk uji keberartian regresi kemampuan pemahaman konsep matematis diperoleh Fhitung=1490,19 dengan nilai FTabel=4,13 dengan demikian 1490,19>4,13 maka Ho ditolak dan Ha diterima sehingga terdapat variabel x mempunyai pengaruh yang kuat dan berarti terhadap variabel Y. Koefisisen korelasi r = 4,090 artinya ada hubungan cukup signifikan antara model pembelajaran kooperatif tipe STAD terhadap kemampuan pemahaman konsep matematis. Koefisien determinasi diperoleh hasil yaitu r2 =61,02% yang artinya keberhasilan siswa dipengaruhi oleh model pembelajaran kooperatif tipe STAD. Dari hasil diatas dapat disimpulkan ada pengaruh pembelaran dengan model kooperatif tipe STAD terhadap kemampuan pemahaman konsep matematis peserta didik

Abstract

This study aims to determine the better improvement of students' mathematical connection and communication abilities between those participating in learning with the Discovery Learning model and those participating in direct learning, as well as to find out the differences in increasing the mathematical connection and communication abilities of students in high, medium and low groups who take learning with Discovery Learning models. Data analysis used a two-mean difference test to determine better improvement between the experimental class and the control class and one-way ANOVA with the Scheffe test to determine better improvement between the high, medium and low groups. Based on the results of the study, it can be concluded that the increase in the mathematical connection and communication skills of students who take part in learning with the Discovery Learning model is better than students who take part in direct learning. The improvement of students' mathematical connection and communication skills in the middle group was better than the high and low groups who took part in learning using the Discovery Learning model
