Abstract

This study aims to determine the increase in students' cognitive abilities through jigsaw learning. This research is a classroom action research using two cycles. The subjects in this study were students of SMA Negeri 4 Kota Serang class XI MIPA in the odd semester of the 2018/2019 academic year. The object of research is students' cognitive abilities. Data on students' cognitive abilities were collected using a cognitive ability test instrument on the concept of plant tissue structure. Data were analyzed descriptively qualitatively. The results showed an increase in students' cognitive abilities before and after the action research. This action research is declared successful if it has achieved a cognitive average score at the minimum that is equivalent to the KKM value = 70. The results showed that the average value of students' cognitive abilities before the research action was 36.32, then increased to 48.23 after the first cycle, and increased again to 72.86 at the final session (cycle II). The conclusion of this study is that the application of the jigsaw learning model in learning is able to improve students' cognitive abilities on the concept of plant tissue structure. Penelitian ini bertujuan untuk mengetahui peningkatan kemampuan kognitif siswa melalui pembelajaran jigsaw. Penelitian ini merupakan penelitian tindakan kelas dengan menggunakan yang dilakukan dalam dua siklus.

Abstract

This study aims to determine the effect of mini-research learning on the communication skills and problem solving abilities of high school students on the concept of ecosystems. The method used in this research is a quasi-experimental method. The population of the study was 10th grade students high school of Pandeglang, Banten. Cluster random sampling was used in this research to fulfil each single treatment and control group. The instruments used in this research were report assessment sheets, test descriptions, and observation sheets. T-test was used to determine mean difference between the control group and the treatment group with α = 0.05. Based on the research results for communication skills, the control group got an average of 50.45 and treatment group got an average of 69.05 with a t-test significance level of 0.00 0.05 (α = 0.05), which means that there is an effect of mini-research learning on students' communication skills. Whereas for the aspect of students 'problem-solving abilities in the control group, it was obtained an average of 43.95 and treatment group was 63.97 with a t-test significance level of 0.00 0.05 (α = 0.05) which means that there is also an effect of mini-research learning on aspects of students' ability to solve problem. Thus it can be concluded that mini-research learning has an influence on students 'communication skills and students' problem-solving abilities.
