Abstract

Learning science provides a challenge for students who have lost interest in learning science, especially chemistry lessons. Resulting in low student learning outcomes, because apart from being abstract in nature, it is influenced by the positive attitudes of students and teacher readiness in managing innovative learning so that the skills that students must have are lacking in dealing with the advancement of 21st century education. The purpose of this study was to determine differences in learning outcomes (cognitive, affective and psychomotor aspects) using the PBL and PjBL learning models in Acid-Base material assisted by macromedia flash which was implemented at SMA Negeri 1 Delitua.Technique The selection of the sample used was purposive sampling with the research design Two Group Pretest – Posttest Design. Data collection techniques used tests for cognitive learning achievement and non tests for affective and psychomotor achievements. Data analysis used the normality test with the Chi Square test, homogeneity through the F-test and two-party hypothesis testing to analyze whether or not there was a difference between the two experimental classes. The results showed that there were differences in cognitive and psychomotor learning outcomes and there were no differences in students' affective aspects between PBL and PjBL models assisted by macromedia flash. Keywords: problem based learning model, project based learning model, macromedia flash, learning outcomes.DOI: http://dx.doi.org/10.23960/jpmipa/v24i1.pp335-348

Abstract

This study was conducted to determine the effect of the Problem Based Learning model on students' learning outcomes and creative thinking skills on colloid material. This study used a pretest and posttest control group design. The sample in this study consisted of two classes, namely class XI IPA 2 with 34 students as the experimental class and class XI IPA 1 with 34 students as the control class determined using a purposive sampling technique. The learning outcomes and creative thinking abilities of students were measured through pretest and posttest and the average value of the learning outcomes and creative thinking abilities of students in the experimental class who were taught using the Problem Based Learning model was higher than the average value of the learning outcomes and creative thinking abilities of students in the control class who were taught using conventional learning. Hypothesis testing with independent sample t-test states that the first hypothesis value is obtained Tcount = 4.16 and it is known that Ttable = 1.99, then tcount tabet means that there is an influence of the Problem Based Learning model on learning outcomes. Furthermore, the second hypothesis is obtained Tcount = 10.85 and it is known that Ttable = 1.99, then Tcount>Ttable means that there is an influence of the Problem Based Learning model on students' creative thinking abilities. From this study it was found that the Problem Based Learning model has an influence on students' learning outcomes and creative thinking abilities on colloid material.
