Abstract

Laboratory literacy is part of scientific literacy, in chemistry learning it is not only learning that is based on understanding concepts, but also requires a laboratory skill to test the truth of theories and to know the benefits of chemical learning in daily life. This study is aimed at describing the level of literacy in prospective science teacher students in the first year. Literacy conditions are needed by the lecturer in designing laboratory activities at the Basic Chemistry Practicum course as part of the course that students must follow. This research is a descriptive study with 35 subjects of science teachers with heterogeneous backgrounds in one of the LPTK in Central Java. Literacy levels include an understanding of the functioning of the tool, the introduction of materials at the basic level, and also an understanding of the laboratory background. Data collection uses reflection sheets that require them to document, describe their functions, and describe laboratory materials and dimensions. The results show that the level of literacy is at a low level in 60% of students, moderate in 35% of students, and high level in 5% of students. Seeing these conditions, before conducting laboratory activities in the first year, matriculation needs to be done through virtual laboratory activities as well as demonstrations to be more effective.

Abstract

A learning disability identification students in understanding the concept of chemical need a right required test. But, a few teachers has not carried out the analysis on understanding the concept of students because as yet there are an instrument used for analysis. One way of determining the understanding the concept of school tuition is using a diagnostic test. This research is developing three tier multiple choice diagnostic intrument to analyze the conceptual understanding of 10th grade students in oxidation-reduction reactions concepts and chemical nomenclature. This study was kind of research and development study. The model of development used is four D model by S. Thigarajan, Dorothy S. Semmel and Melvyn I. Semmel. Research subjects is 10th grade science students of Semarang Islamic Senior High School. Instrument that used is three tier multiple choice diagnostic test instrument consisting of 23 item questions. Every item question has five alternative answers in tier one, five alternative reasons in tier two, and sure whether or not to answer in tier three. Research result shown that the developed instrument was good and valid with instrument reliability value was 0,90 and instrument validity value was 92%. Data result was analized descriptively and quanitatively. Result of students conceptual understanding shows that 53.56% of students understand the concept, 44,15% of students are misconception, 0,60% of students are chancy, 0,97% of students less understand the concept, 0,72% of students do not understand the concept.

Abstract

This study aims to analyze the types of errors that are dominant or often occur in students in doing stoichiometry problems through Polya steps. The research was conducted in Semarang State Senior High School 6 with 36 subjects in class X IPA 2 who were then grouped with the criteria of 2 upper group students, 2 middle group students, and 2 lower group students. The study was conducted by giving written tests in the form of description tests and interviews. Based on the results of the study, the more dominant mistakes made by 6 students as research subjects were (i) conceptual errors of 33% due to students not understanding the concepts used to solve the problem. Other mistakes made by students include: (ii) errors using data as much as 3%; (iii) technical errors of 10% due to students not being careful in carrying out calculations; (iv) conclusions as much as 54% because students conclude the final results and students do not check their answers. Therefore, in the learning process the teacher should explain the steps in working on the problem using the Polya step and emphasize the steps of understanding the problem and planning a solution so that the students' mistakes in working on the stoichiometry material problem are not repeated. Students are given more and varied practice exercises to further enhance their understanding of material concepts.

Abstract

The ability to express good ideas in a discussion and answer question can affect students' creative thinking abilities. The availability of wifi in schools is already very good, so blended learning based learning models can be applied to improve the learning process in schools. This study aims to determine the ability of students to think creatively in acid-base material using project-based learning combined with blended learning methods. The research method used is pre-experimental. The research design used is one-shot case study. This research was conducted with the stages of preparation, implementation, data retrieval, then analyzed, discussed, and concluded as a result of the research. The research subjects were taken by purposive sampling technique. The subjects in this study were students of class XI MIPA 3.4 of SMAN 1 Salatiga. Data collection techniques are carried out by testing creative thinking skills through essay or essay questions, observation sheets to measure the ability to think creatively and assessment of natural indicator projects. The average results of the percentage of creative thinking ability indicate that 67% of students are in a good category. The highest percentage for each indicator of creative thinking ability is detailed thinking skills (77%), fluency (72%), flexible thinking skills (65%) and original thinking skills (44%). The average rating percentage for making natural indicator projects is 83.3% with a very good category.

Abstract

Project-based learning is a complex task based on challenging questions or problems, involving students in design, problem solving, decision making, or investigative activities, giving students the opportunity to work autonomously then produce products. The study aims to determine the effect of project-based learning of chemical products on understanding the concepts and science process skills of high school students. The research method was an experiment using modified pretest-posttest group comparison design. The sampling technique used is cluster random sampling. Class XI IPA 5 as an experimental class and class XI IPA 1 as a control class. The analysis technique used is the average difference test, the effect analysis between variables, and the determination of the coefficient of determination. The results obtained by the average learning outcomes and science process skills of the experimental class 80.61 and 80.89 while the control class 77.08 and 74.64. Analysis of influence between variables resulted in biserial coefficient values of 0.33 for learning outcomes and 0.40 for science process skills. Calculation of the coefficient of determination of the effect of project-based learning contributes 10.89% to learning outcomes and 16% to science process skills. Based on the results of the study, it was concluded that project-based learning had an effect on the understanding of concepts and science process skills of class XI students of SMAN 2 Mranggen on solubility and solubility products.

Abstract

One of the factors that lowers the students' conceptual understanding of acid-base material is the limited learning resources in the form of worksheets. Worksheets can be developed through Predict, Observe, Explain (POE) learning models and utilize local potential in South Kalimantan. This is an effort to improve students' conceptual understanding of the material. Therefore, the purpose of this study was to develop an acid base worksheet using the local potential based POE model of South Kalimantan and find out the feasibility of the worksheet. The type of research used was research and development which adopted from the procedure of developing Borg and Gall. The object of this development research is students of class XI MIPA MAN Banjarmasin and students of Tadris Kimia UIN Antasari. The data collection technique uses a worksheet feasibility test questionnaire given to the research object. The data analysis technique uses quantitative descriptive on the results of filling out the questionnaire by the validator and research object. The research result show that the acid base worksheet using the local potential based POE model of South Kalimantan is feasible to use with a revision of 92.09%. While the results of the trials on the research object, the worksheet is classified as very good with a value of 82.78%.
