EFFECTS OF PROBLEM-BASED INSTRUCTIONAL STRATEGY ON SENIOR SCHOOL STUDENTS’ PERFORMANCE IN CIRCLE THEOREMS
Abstract
Abstract
This study was conducted with the aim of determining the effects of Problem-Based Instructional Strategy (PBIS) on students’ performance in circle theorems in Mathematics. The study is a quasi-experimental type of non-randomized, nonequivalent pre-test and post-test control group involving a 2 x 2 x 3 factorial design, indicating instructional strategies at two levels (Problem-Based Instructional Strategy and conventional method), gender at two levels (male and female) and scoring level at three levels (high, moderate and low level). The target population was all Senior Secondary School students in Ogbomoso, Nigeria. A total of 244 students participated in the study. The research instrument used is Circle Theorems Performance Test (CIRTPT). t-test statistics and ANCOVA were employed to analyze the data. The findings of the study revealed that: there was a significant difference in the performance of students taught circle theorems using PBIS and those taught with conventional method (t(242)=2.87; p<0.05); there was no significant difference in the performance of male and female students taught circle theorems using PBIS (t(110)=0.52; p>0.05); and there was no significant difference in the performance of students on the basis of score levels when taught circle theorems using PBIS (F(2,108)=2.31; p> .05).

Tujuan penelitian ini adalah untuk mengetahui pengaruh Strategi Problem Based Learning (PBM) terhadap kinerja siswa terkait teorema lingkaran dalam Matematika. Penelitian ini merupakan jenis eksperimen semu dengan jenis kelompok kontrol pre-test dan post-test non-randomized, nonequivalent yang melibatkan desain faktorial 2 x 2 x 3, yang menunjukkan strategi pembelajaran pada dua tingkat (Strategi Pembelajaran Berbasis Masalah dan metode konvensional), gender pada dua tingkat (laki-laki dan perempuan) dan tingkat penilaian pada tiga tingkat (tingkat tinggi, sedang dan rendah). Populasi dalam penelitian ini adalah semua siswa Sekolah Menengah Atas di Ogbomoso, Nigeria. Sebanyak 244 siswa berpartisipasi dalam penelitian ini. Instrumen penelitian yang digunakan adalah Circle Theorems Performance Test (CIRTPT). Statistik uji-t dan ANCOVA digunakan untuk menganalisis data. Hasil penelitian menunjukkan bahwa: terdapat perbedaan yang signifikan kinerja siswa yang diajar teorema lingkaran menggunakan PBM dan siswa yang diajar dengan metode konvensional (t(242)=2,87; p<0,05); tidak ada perbedaan yang signifikan dalam kinerja siswa laki-laki dan perempuan yang diajarkan teorema lingkaran menggunakan PBM (t(110)=0,52; p>0,05); dan tidak ada perbedaan yang signifikan dalam kinerja siswa berdasarkan tingkat skor ketika diajarkan teorema lingkaran menggunakan PBM (F(2,108)=2,31; p> 0,05).
