PENGARUH MODEL PEMBELAJARAN PROBLEM BASED LEARNING (PBL) TERHADAP KEMAMPUAN PEMECAHAN MASALAH MAHASISWA

Tujuan dalam penelitian ini adalah untuk mengetahui apakah peningkatan kemampuan pemecahan masalah mahasiswa dengan model Problem Based Learning (PBL) lebih baik dari pembelajaran langsung. Penelitian ini merupakan penelitian quasi experiment dengan rancangan pretest-posttest control group design. Sampel dalam penelitian ini adalah mahasiswa semester V kelas A dan B IKIP PGRI Pontianak dengan teknik cluster random sampling. Instrumen penelitian yang digunakan adalah soal tes kemampuan pemecahan masalah pada mata kuliah matematika diskrit. Hasil penelitian menunjukkan bahwa terdapat peningkatan kemampuan pemecahan masalah dimana pengujian hipotesis dengan menggunakan uji Mann-Whitney diperoleh nilai Asymp. Sig. (2-tailed) sebesar 0,000 lebih kecil dari 0,05 maka rata-rata kemampuan pemecahan masalah dengan menggunakan model PBL lebih besar daripada rata-rata kemampuan pemecahan masalah dengan menggunakan pembelajaran langsung. Dari hasil penelitian dapat disimpulkan bahwa mahasiswa yang pembelajarannya menerapkan pembelajaran dengan model PBL peningkatan kemampuan pemecahan masalah secara signifikan lebih baik dibandingkan dengan siswa yang pembelajarannya menggunakan pembelajaran langsung. The purpose of this study was to determine whether the increase in student problem solving abilities with the Problem Based Learning (PBL) model was better than direct learning. This research is a quasi experimental study with a pretest-posttest control group design. The sample in this study were the fifth semester students of class A and B IKIP PGRI Pontianak with cluster random sampling technique. The research instrument used was a test problem solving ability in discrete mathematics courses. The results showed that there was an increase in problem solving abilities where hypothesis testing using the Mann-Whitney test obtained Asymp. Sig. (2-tailed) of 0,000 less than 0,05, the average problem solving ability using the PBL model is greater than the average problem solving ability using direct learning. From the results of the study, it can be concluded thet students whose learning applies PBL model increase their problem solving abilities significantly better than students whose learning used direct learning.

7-Step PBL: Problem Solving Ability of Students in Work and Energy

The purpose of this study was to determine the level of problem solving skills of students in the 7-Step PBL material work and energy materials.

There are three main findings in this study, the first amounted to 69.35% the average level of problem solving abilities of students is still at level 2 (moderate). Second, even after participating in learning using the 7-Step PBL method, the average problem solving ability of students has not yet reached level 4(high). Third, in indicator problem number 2 "relationship work and kinetic energy" there are no students who have problem-solving skills at level 4(high).

The Application of The Polya's Steps Reviewed from Problem-Solving Ability in Two-Variable Linear Equation System (SPLDV)

The ability of students in this school is low in understanding the questions given by the teacher. As a result they find it difficult to know the steps on how to solve the problem. Efforts that can be done are implementing Polya's steps.Quasi-experimental research was conducted in this study with the Randomized Control Group Only Design. Students of class VIII at this school are used as population. The experimental class is class VIIIA and the control class is class VIIIB. Final test data in the form of essays obtained were analyzed by t test. The result is the average problem solving ability with the application of Polya's steps, 78.23 and the control class, 72.38, with achievement in the experimental class 81% and in the control class, 48%. After being analyzed, t_count = 2.33 and t_table = 1.68 with a confidence level of 95% so that t_count > t_table (2.33 > 1.68), meaning that the proposed hypothesis is accepted and the ability of students in solving problems using Polya steps is higher rather than without applying these steps.
