Abstract

The purpose of this study is to see the difference in the average learning outcomes of mathematics in statistics materials using the Problem Based Learning learning model and the direct learning model. The type of research used is pseudo-experimentation. The research design used is The Matching Only Posttest Control Group Design. The sample consisted of 2 normal and homogeneous classes determined through lottery, class VIII A totaled 16 students as an experimental class and class VIII B totaled 16 students as a control class located at Rurukan Christian Junior High School in Tomohon city. The average statistical learning outcomes of experimental class students were 83.63 and the average learning outcomes of control class students were 78.44. The study statistics used a t-test with tcount = 3.44 > ttable = 1.69 with a real level of α = 0.05. It is concluded that the average learning outcomes using the Problem Based Learning learning model are more than the average learning outcomes using the direct learning model.

Abstract

English The study aims to analyze the types of errors made by students in solving algebraic operations material questions for class VII SMP Dominico Savio Manado and to find out the factors that cause students to make these mistakes. The type of research used in this research is descriptive qualitative. Data collection techniques were carried out by giving tests and inetrviews. The results of the analysis in this study indicate the types of errors made by class VII students of SMP Dominico Savio Manado in solving problems on the operation material of algebric forms, namely conceptual errors of 66,67%, procedural errors of 55,55%, and computational errors 83,33%. The factors that cause students to make mistakes, namely students do not understand the meaning of the questions given, students are less careful in performing arithmetic operations, and students are in a hurry to solve questions abaout operations in algebraic forms.
