PENGARUH MODEL PEMBELAJARAN BERBASIS PROYEK TERHADAP SIKAP ILMIAH DAN KONSEP DIRI SISWA SMP
Abstract
Penelitian ini bertujuan untuk: (1) menganalisis perbedaan sikap ilmiah dan konsep diri antara siswa yang belajar dengan model pembelajaran berbasis proyek (MPBP) dan siswa yang belajar model pembelajaran konvensional (MPK), (2) menganalisis perbedaan sikap ilmiah antara siswa yang belajar dengan MPBP dan siswa yang belajar dengan MPK, (3) menganalisis perbedaan konsep diri antara siswa yang belajar dengan MPBP dan siswa yang belajar dengan MPK. Penelitian ini merupakan kuasi eksperimen, dengan rancangan penelitian postest only control group design. Populasi dalam penelitian ini adalah siswa kelas IX SMP Negeri 3 Banjarangkan tahun pelajaran 2014/2015 yang berjumlah 132 siswa, dengan sampel 90 siswa. Data yang diperoleh dianalisis dengan statistik deskriptif dan MANOVA satu jalur. Berdasarkan hasil analisis, ditemukan hasil sebagai berikut. Pertama, ada perbedaan yang signifikan antara model pembelajaran terhadap sikap ilmiah dan konsep diri secara bersama-sama (F=128,3; p<0,05). Kedua, terdapat perbedaan yang signifikan sikap ilmiah antara kelompok siswa yang belajar dengan MPBP dan kelompok siswa yang belajar dengan MPK (F=117,751; p<0,05), dimana mean kelompok siswa MPBP = 75,37 dengan kategori tinggi, sedangkan mean kelompok MPK = 65,38 dengan kategori sedang. Hasil pengujian LSD diperoleh ǀµi - µjǀ >LSD dengan ǀµi - µjǀ = 9,98888 dan LSD = 3,66369, artinya sikap ilmiah siswa berbeda secara signifikan antara kelompok MPBP dengan MPK. Ketiga, terdapat perbedaan yang signifikan konsep diri antara kelompok siswa yang belajar dengan MPBP dan kelompok siswa yang belajar dengan MPK (F=151,981; p<0,05), dimana mean MPBP = 76,41 dengan kategori tinggi, sedangkan mean MPK = 62,97 dengan kategori sedang. Hasil pengujian LSD diperoleh ǀµ i- µjǀ >LSD dengan ǀµ i- µjǀ = 13,4444 sedangkan LSD = 4,340411, artinya konsep diri siswa berbeda secara signifikan antara kelompok MPBP dengan MPK.

This study aimed at (1) finding out and analyzing the difference between student’s scientific attitude and students’ self concept among the students who were taught by Project-based Learning (PBL) and those who were taught by convensional learning (CL), (2) finding out and analyzing the difference of student’s scientific attitude between the students who were taught by PBL and CL, (3) finding out and analyzing the difference of students’ self concept between the students who were taught by PBL and CL.This study was a quasi eksperiment research with posttest only control group design. The population of this study consisted of 132 year IX students of SMP Negeri 3 Banjarangkan who are selected by using random sampling. The sample of this study was 90 students based on the technique. The data obtained were analyzed by MANOVA One Path. The result showed that : First, there was a significant effect between learning model on student’s scientific attitude and students’ self concept (F = 128,3; p < 0,05). Second, there was a significant difference of student’s scientific attitude between the students who were taught by PBL (F = 117,751; p < 0,05) in which the students’ mean score of PBL = 75,37 was higher than that of CL = 65,38. Based on the testing of LSD obtained with ǀµ i- µjǀ >LSD while ǀµi - µjǀ = 9,98888 and LSD = 3,66369, so the scientific attitude of students concluded differ significantly between groups PBL with CL. Third, there was a significant difference of students’ self concept between the students who were taught by PBL (F = 151,981; p < 0,05) in which the students’ mean score of PBL = 76,41 was higher than that of CL = 62,97, with enough category. Based on the testing of LSD obtained with ǀµ i- µjǀ >LSD while ǀµ i- µjǀ = 13,4444 and LSD = 4,340411, so the conclusion of the self concept of students differ significantly between groups PBLwith CL.
