Abstract

Communication is the process of delivering messages from the communicator (source) to the communicant (receiver) through certain media to produce certain effects or goals by expecting feedback or reciprocity. The purpose of this study was to analyze the communication patterns carried out in chemistry learning at SMA Negeri 1 Sungai Raya. This research uses a descriptive method. The research subjects were chemistry subject teachers and students of class XI IPA 3 and XI IPA 4 SMA Negeri 1 Sungai Raya in the 2019/2020 school year. The instrument used to analyze teacher and student communication patterns is Matrix verbal interaction category system (VICS) Flander developed by Amidon and Hunter. The results showed that the communication patterns that occur are one-way communication patterns in which communication patterns are still discussed by the subject teacher

Abstract

The purpose of this research is to describe the ability of scientific literacy junior high school students in natural science subjects. The methodology of this research is descriptive qualitative. The total of students who involved in this qualitative research from SMP Negeri 2 Pontianak and SMP Negeri 10 Pontianak are 124. The value of scientific literacy skill used written tests which are given to the students by multiple choice and essay tests. The answers of the students are analyzed by the aspects of scientific literacy. Based on the analysis, the average percentage results of each aspect of scientific literacy are content knowledge in explaining scientific phenomena (27.25%), procedural knowledge in interpreting data and evidence scientifically (53.34%), epistemic knowledge in interpreting data and evidence scientifically (17.4%), and epistemic knowledge in evaluating and designing scientific inquiry (33.23%). Based on the grades achieved by students, it is divided into three categories of grades, high, medium, low. Based on the results of research the average scientific literacy ability of students included in the low category with a percentage of 73.02%. This proves that a small proportion of students have scientific literacy skills.

Abstract

AbstractThis research was conducted to find out  the difference in learning outcomes of VIII grade students of Kemala Bhayangkari Middle School on food additives taught by using inquiry-based modules and those taught without using inquiry-based modules and  of the effect of inquiry-based modules on student learning outcomes. This research was a conducted using quasi-experimental study with the Nonequivalent Control Group Design research design. The sample in this study was class VIII A as an experimental class and class VIII C as a control class. The data collection technique used was the measurement technique. Data collection tools used were essay-shaped tests. The was Mann Whitney U-test showed that there were differences between the learning outcomes of Grade VIII students of Kemala Bhayangkari Middle School on food additives taught by inquiry-based modules and students taught without using inquiry-based modules Based on Effects Size calculation of 0.97, it was classified as the high category. Learning using inquiry-based modules has an effect of 33.40% on improving student learning outcomes.Keyword :Food additives, learning outcomes, Module based inquiry

Abstract

This study aims to determine whether the differences in communication skills of students who use the Peer Assessment technique with students who use Teacher Assessment and how much the influences to students. The research method was using pre-experimental design with Intact-Group Comparison. The sample of this research is grade VII students of SMP Negeri 19 Pontianak.

Abstract

This study aims to find out 1). Differences in student learning outcomes using powtoon-based learning media and using powerpoint media in class X students of SMK PGRI Pontianak. 2). Motivation of students after using powtoon-based learning media and using powerpoint 3). the effect of powtoon-based learning media on student learning motivation in petroleum material at SMK PGRI Pontianak. The form of this research is quasi-experimental research with a non equivalent control group design. The sample of this study were students of class X TKR as an experimental class and class X TSM as a control class. Data collection tools used in this study were test results in the form of essays, motivational questionnaires, student observation sheets and interviews. Learning outcomes were analyzed using the U-Mann Whitney test. The results of data analysis showed that there were differences between the learning outcomes of students who were taught using powtoon-based learning media and those who used conventional learning namely powerpoint. Learning with powtoon-based learning media gives an effect of 24.59% to the improvement of student learning outcomes. This is supported by a student motivation questionnaire towards learning with a powtoon of 93% and with a powerpoint of 73.2%.

Abstract

This study aims to describe the 54critical thinking skills of class X science students of SMAN 2 Pontianak, Panca Bakti High School and SMAN 5 Pontianak in Stoichiometry material. This form of research uses descriptive qualitative research. The research sample was students of class X IPA of SMArN 2 Pontianak, Panca Bakti and SMAN 5 Pontianak, totaling 84 students. Students' criticaae8l thinking skills are measured using written tests in the form of essays, and unstructured interviews. The research instrument was validated using the Gregory test matrix. The results obtained that the critical thinking skills of class X science students of SMAN 2 Pontianak, SMAS Panca Bakti, and SMAN 5 Pontianak are classified as less skilled. This is indicated by the low average percentage of students' critical thinking skills of 2.4836 or 62.09%. This proves only a small proportion of students who have critical thinking skills of students on stoichiometry material.
