Thinking Ability

Solution material is one of the materials that requires a student's level of understanding at the critical thinking level. Critical thinking skills train students to learn to find and solve problems using scientific methods based on real experiences encountered and experienced directly. To be able to find the concept of knowledge based on existing realities, an appropriate learning model is needed, namely a problem-based learning model. This study aims to determine students' critical thinking skills. The type and design of this research is development research with a nonequivalent control group design. The samples of this research were students of semester 2, Biology Education Study Program, University of Flores. This research was conducted from April-June 2020. Data were collected using the critical thinking ability test technique of students in the chemical solution subject, followed by processing and analyzing data using the prerequisite analysis test in the form of normality test, homogeneity test, and t-test. The data analysis shows the significance value of the normality and homogeneity test, namely α> 0.05, while for the t-test α <0.05. From these results prove that problem-based learning can improve students' critical thinking skills in chemistry subject matter solution

Implementation of learning in class 11th MAN 1 and MAN 2 Banda Aceh City Students only get information without going through discussion activities, students who are not brave enough to express ideas or ideas, so that students are not trained in using their critical thinking skills. This study aims to determine the improvement of students' critical thinking skills through the application of the STEM-based discovery learning model to the motion system concept. The research approach used is quantitative with the type of pre-experimental research. The research design used is the one-group pretest-postest design. The population was all of 11th grade students, amounting to 292 people. The sampling technique used was a total sampling. The sample in this study consisted of 292 students. The instruments in this research were pretest and posttest multiple choice questions with reasoned. Data analysis consisted of normality test, paired sample t-test at a significant level of 0.05 and n-gain. The results of the paired sample t-test obtained tcount 48 and value (ρ.001), so it was concluded that there were differences in critical thinking skills and learning outcomes of students before and after learning with the application of the STEM-based discovery learning model to the motion system concept. The results of the n-gain test using the Meltzer formula showed that the gain in critical thinking skills was 0.85, so there was an increase in critical thinking skills with a high category.

This research was motivated by the still limited learning of mathematics as a means of supporting learning in the 2013 Curriculum. The purpose of this study was to produce some products in the form of learning devices (syllabus, RPP and LKPD) on the material for the flat side building of VIII Middle School with discovery learning models that meet valid, practical, and effective criteria for improving students mathematical critical thinking skills. Learning tools are developed using the 4-D model, which are define, design, develop and assess. The research instrument used was an instrument of validity in the form of a validation sheet to assess the feasibility of the syllabus, RPP and LKPD as well as a practical instrument in the form of a teacher observation sheet activity in applying the discovery learning model and student questionnaire responses to assess the practicality of LKPD. The results of the validation of the experts stated that the product developed reached a valid category with an average rating of 76.67% for syllabus, 76.67% for RPP and 88.04% for LKPD. Learning devices are considered very practical in small group trials with an average response of 96.44% students and large group trials from the observation sheet of teacher activity 93.71% and the average response of students 87.77%. The learning tools have been proved to improve students mathematical critical thinking skills in terms of an average N-gain of 0.53 in the medium category.
