Abstract

Abstract. This study shows the effect of the method of problem solving on cognitive abilities and critical thinking skills in making proposals of educational research articles. This study used an experimental method, which was implemented in January 2015 until July 2015. The sample consisted of one class of a study that students of Chemical Education FKIP UISU TA. 2014/2015. The results were obtained using two test method is to test the cognitive domain that is a multiple choice test and critical thinking skills in the form of making a research proposal. From the results of the analysis, there is the influence of problem solving methods to the learning outcomes of students' critical thinking and student learning outcomes multiple-choice test on the results of student learning materials Research Methods. No influence student results test multiple-choice to the learning outcomes of students' critical thinking on the results of student learning course material research method there is no interaction between the two methode tests with the use of methods of problem solving, but no effect of the use of methods of problem solving on critical thinking ability of students in results students learn the material Research Methods. Keywords: methods of problem solving, critical thinking, cognitive ability, research methods

Abstract

Abstract. This study aims to determine: 1). The learning outcomes differences between  students who learned with an integrated model of Problem Based Learning (PBL) Internet media and Internet media integrated Direct Instruction (DI) and Direct Instruction (DI) learning. 2) The difference of character values of tolerance, communicative, confidence, respect democratic achievements and spreading among the students who learned with an integrated model of PBL and the Internet media DI teaching model integrated Internet media as well as the DI teaching model. 3) There is an interaction between the characters tolerant, communicative, confidence, appreciate spreading democratic achievements and the learning outcomes of students who learned with an integrated model of PBL and the Internet media DI teaching model integrated Internet media as well as the DI teaching model. 4) what cognitive domains spreading the students who learned with an integrated model of PBL and the Internet media DI teaching model integrated Internet media as well as the DI teaching model.

Student learning outcomes measured by achievement test instrument using the normalized gain, while for the characters used questionnaires and observation. The analysis technique used Anacova significant at α 0,0. The hypothesis was tested using univariate general linear models. The results showed that there were significant differences in learning outcomes of students who received learning PBL model with an integrated internet and integrated Internet Direct Instruction and Direct Instruction Model .2. There are differences in character values of tolerance, communicative, confident, achievement and respect democratic spreading among the students who learned with an integrated model of PBL Internet and DI model of integrated Internet and DI.
