Abstract

Abstract: According to demands of curriculum 2013, assessment carried out on school should have led to increasing of higher order thinking skill. The lack of availability of questions are specifically designed to develop student’s higher order thinking skill causes students are not really proficient in solving higher order thinking skill questions. This study was research and development research purposing to determine development steps and quality of higher order thinking skill test instrument in one of high schools chemistry topic, i.e. colloid. The process of developing a higher order thinking skill test instrument used a formative research designed by Tessmer through 4 stages, namely: preliminary, self-evaluation, prototyping (expert reviews, one-to-one and small group) and field test. The data were obtained from the results of filling out validation sheets by expert reviews, questionnaires filled out by students, and test/trial of higher order thinking skill test instrument on students. The results of the development were categorically valid logically and empirically. The reliability of the test instrument was 0,65 with the high category. The item’s difficulty level was in the medium category. Six questions had good distinguishing power and one question had enough distinguishing power. The higher order thinking skill of students were in excellent, good, adequate, lacking and very poor categories respectively: 15,14%; 12,12%; 42,42%; 24,24%; 6,06%.

Abstract

The obstacles that must be faced in the 2013 Curriculum are the limitations of the media to support the learning process on acid-base material. Research has been conducted with the aim of developing Student Worksheets (LKS) on chemistry subjects based on the 2013 Curriculum which is inquiry based on Acid-Base material for class XI SMA / MA and equivalent. The research was conducted at SMA Al-Hikmah Surabaya using the 4-D development method (Define, Design, Develop, Disseminate). The trial was limited to 19 students of class XI MIA who were randomly selected. This study uses a One Shot Case Study design without a comparison group and a pre-test for the trial phase where students will get a test after students are given treatment using a developed worksheet. The instruments used were study sheets, validation sheets, test sheets and student response questionnaires. Based on the results of the research it is known that this LKS has 76% content feasibility, 90% presentation, 82.5% language, and conformity to the 88% inkuri model based on validation besides that student learning outcomes achieve classical completeness of 94.73% and student responses to student worksheets which is developed tested positive.

Abstract

There are still many misconceptions in the buffer solution material based on the results of pre-research that has been done. Therefore, it is necessary to to make efforts to reduce misconceptions. This research aims to determine the validity of the three-tier-test diagnostic test instrument and Student Worksheet (LKPD) to reduce student’s misconceptions through conceptual change model on buffer material. This research and development method uses a 3-D model which is a modification of the 4-D model, namely (1) define; (2) design; and (3) development. The validity of the instrument and LKPD in terms of content validity and construct validity. The content validity of the instruments and LKPD respectively obtained an average percentage of 94.00% and 92.44%. While the construct validity of the instruments and LKPD respectively obtained an average percentage of 91.00% and 86.47%. This results shows that the three-tier-test diagnostic test instrument and LKPD through conceptual change model developed were declared very valid.

Abstract

Scientific work skills are one skill needed students as prospective educators to be able to face the demands of education 21st century. The purpose of this study to describe work skills Scientific students of Chemical Education FKIP Tanjungpura University on the material salt hydrolysis. The form of research used is descriptive research. Based on the method, this research uses descriptive analysis method. The subjects of this study were students of Chemical Education FKIP University Tanjungpura Class of 2018, amounting to 48 people. The instrument used namely a matter of scientific work skills and interview guidelines. Based on the category of skills obtained by the average KKI chemistry education students class of 2018 in the skilled category (62.5%). From the aspect of KKI, students chemical education formulates the problem in the skilled category (74.74%), formulate a hypothesis in the category of skilled enough (57.75%), analyze the data in the skilled category (64.65%), and formulating conclusions in the sufficient category skilled (45.05%). The implication of this research is that the research results can be used as input for lecturers to pay attention to appropriate learning models to improve students scientific work skills.

Abstract

Critical thinking and creative thinking are important dimension in teaching of 21st century to facing the challenges of the industrial revolution 4.0. The aim of this research was to analyze undergraduate preservice teachers’ critical and creative thinking skills on a biochemistry course. It was conducted using case study to analyse real circumstance that happened in biochemistry course. The instruments was observation sheet, test items of critical thinking skills, test items of creative thinking skills and questionnaires were used to determine the responses students towards learning activity. Participant was 30 undergraduate preservice chemistry teachers in 2015. The finding of this research showed that biochemistry course only emphasizes on critical thinking skills and not provided briefing creative thinking skills. This means that the biochemistry course has not showed students’ balance skills on critical and creative thinking skills. This study suggest that need further research to develop a biochemistry program who can improve students’ critical thinking and creative thinking.
