Abstract

This study aims to describe the effectiveness of project-based learning in improving students' critical thinking skills. The research design used was the matching only pretest and posttest control group. The population in this study were all students of class XI MIPA, one of the high schools in Bandarlampung. The research sample was students of class XI MIPA 6 and XI MIPA 4. The data analysis technique used is the non parametric statistical test using U Man Whitney. The results of the study showed that the average posttest of critical thinking skills in the experimental class was greater than in the control class. the average n-gain in the experimental class is medium and low in the control class, indicating that project-based learning is effective in improving students' critical thinking skills. Keywords: critical thinking skills, waste cooking oil, project-based learning

Abstract

This study aimed to describe the effectiveness in project-based learning of waste cooking oil recycling to improving students’ high order thinking skills. The research design used was the The Matching-Only Pretest-Posttest Control Group Design. The population in this research was all of students in grade XI MIA one of Senior High School in Bandarlampung. The sample of the research was the students of class XI MIA 4 and XI MIA 6. The data analysis technique used was non parametric statistic test using Mann Whitney U to postestt value. The results of this study it can be seen from postest value. Postest value in the experiment class that is greater than the postest value in the control class as well as the <g> on the medium categorized in the experimental class and in the low control class indicate that project-based learning of waste cooking oil recycling can improve students' high order thinking skills. Keywords: high order thinking skills, waste cooking oil, project-based learning

Abstract

This study aimed to determine the significant differences of  learning achievement at 10th grade students of SMA Negeri 1 Kalasan between the application of conventional learning models with learning models Relating, Experiencing, Applying, Cooperating, Transferring (REACT) in the domain of knowledge, attitudes, and skill  on the Basic Chemical Law materials. This study also aimed to know students’ response to learning using REACT model. This research was an experimental using Quasi Experimental Design, namely Posttest Only with Nonequivalent Groups Design. The population in this study was all students of 10th grade SMA 1 Kalasan in the academic year 2017/2018. This study used two classes as the study sample. The data were analyzed using Independent Samples T-Test parametric test for the knowledge and attitude domain, and Mann Whitney U non parametric test for the skill domain. The results of this study can be concluded that (1) there was  no significant difference in student learning achievement in the  knowledge domain, (2) there was  no significant difference in student learning achievement in the attitude domain, and (3) there was  significant differences in student learning achievement in the skill domain  between the application of conventional learning models with REACT learning models in the  Chemical Basic Law and (4) students gave a good response to the REACT learning model performed.

Abstract

This study aims to improve students' critical thinking skills (CTS) in disadvantaged, outermost and foremost areas, namely in Indonesia's border elementary schools which are full of limited educational facilities. This research was conducted on science subjects in grade VI SDN 29 IDAI on the balance of ecosystems. The method used for the research is the experimental method, which is Quasi Experiment because conditions do not allow for the control class to be held. The research design is one group pretest posttest design, where before the treatment is given, the sample is first given a pretest (initial test) and at the end of the learning sample is given a posttest (final test). CTS aspects developed in this study include identifying criteria for possible answers, mentioning examples, giving reasons, and drawing conclusions. Based on the results of data analysis in the form of the results of the pre-test and post-test, there was an increase in students' average critical thinking skills, starting from 32% (less) in the pre-test to 75% (good) in the post-test. The application of discovery-inquiry method with work sheet illustrated media is also able to increase student learning outcomes to an average value of 72.38 with a graduation rate. The minimum criteria for completeness in classical is 84.62%.

Abstract

Organic chemistry is often regarded as a difficult subject which deters learners and is associated with poor performance. Our research aims to examine some of the challenges that students face in learning organic chemistry topics related to acid/base and resonance structures theories. For this purpose, organic chemistry exams were analyzed in regards to these troublesome topics. A questionnaire was administered to further understand some of the challenges students face when enrolled in organic chemistry. Our data show that students face several challenges learning these topics and that there is a need to change the way these topics are addressed in instruction.
