Peningkatan Penalaran Ilmiah Siswa melalui Pembelajaran Guided Inquiry Berstrategi Scaffolding pada Materi Suhu dan Kalor

The purpose of this research was to analyze the students’ scientific reasoning skills in the guided inquiry learning integrated of scaffolding in heat and temperature. The research used mixed-method with embedded experimental design. The subject of this research was 29 students of class X in Sidoarjo state high school. The instrument consists of treatment and measurement instruments. The treatment instruments consist of syllabus, lesson plan, and student worksheet. The measurement instrument consists of scientific reasoning skills test. The test development based on scientific reasoning pattern proposed by Lawson with a reliability of 0.848. The quantitative data on students’ scientific reasoning skills was analyzed using Wilcoxon-test, while qualitative data was analyzed by reducing data and coding using a scientific reasoning pattern rubric. The results show that students’ scientific reasoning skill in heat and temperature increased after following the guided inquiry learning integrated of scaffolding. The students have been able to use information to determine whether a conclusion is likely to be true or not, but students are still unable to recognize and interpret relationships in situations described by observed or abstract variables.

Legal Reasoning Pattern Based On Trancendental Values : A Reflection on Legal Reasoning Based on Positivism Values

Purpose of the study: This article aims at finding out the pattern of legal penalties for transcendental valuesMethodology: This research is conducted using descriptive philosophical normative study methods. As a secondary legal material, this writing draws on literature, papers, journals, and research related to this writing.Main Findings: Positivism-based legal reasoning has failed to accommodate all the interests and legal needs of the community in realizing justice and prosperity. The pattern of legal reasoning based on transcendental values is a choice because it is related to the understanding that places the law for justice and public welfare.Applications of this study: This study can give benefit to thinkers in the field of legal studies thinking to make a breakthrough in the formation of new lawsNovelty/Originality of this study: The use of the basics of transcendental law can be made as a new breakthrough to realize a just and prosperous law

Identification of Students Misconception Using Two-Tier Diagnostic Test Completed with Certainty of Response Index (CRI) on Topic Partial Salt Hydrolysis

<p>This study’s aim was to find misconception pattern on partial salt hydrolysis on eleventh grade student science major at SMA Negeri 2 Sukoharjo. Misconception was identified using two-tier diagnostic test completed with CRI supported by observation on learning process also interview. Two-tier diagnostic test composed of 16 questions. The approach of this study was qualitative description which was held in February-June 2018. The subject of this study were the eleventh grade students class IPA 1 and IPA 4 as many as 72 students. According to the result showed that there was misconception on almost every concept’s part. Based on the student answer analysis result shows if the pH, relative atomic mass, and volume were known student were having biggest misconception on counting salt’s mass are, 75%. The reason of misconception that occurs on partial salt hydrolysis is come from the student it self that is student’s uncomplete reasoning pattern.</p>

Problem Solving Heuristic to Develop Scientific Reasoning

Scientific reasoning patterns of students formal operational base on the implementation of problem solving heuristic methods has been obtained. The aim of this research is knowing the influence of heuristic problem solving method that has been designed on practicum sheet of discovery learning model to develop scientific reasoning of students. The samples are 32 students in junior high school at 11-13 years old. The methods are CTSR test of scientific reasoning by Lawson and interview. The research design is one grup pretest-posttest. The results indicated that problem solving heuristic methods can be a factor to develop scientific reasoning of students. The lowest level of scientific reasoning (concrete reasoning pattern) is decrease 34,38%. The middle level of scientific reasoning (transitional reasoning pattern) is increase 31,25%. The highest level of scientific reasoning (formal reasoning pattern) is increase 3,13%. Heuristic methods helping students to develop scientific skills, such as setting hypotheses, modifying variables, and analyzing results of research. The scientific reasoning pattern can not be classified by age. People who has older of age has not impact in high scientific reasoning level than younger people. If someone fail on concrete aspect, it is not necessarily that person will be fail in formal aspect.

Opportunistic Process Planning: A Knowledge Based Technique for CAPP Applications

Feature based Computer Automated Process Planning applications often suffer from exponential growth of the search space and thus CPU-time, with increasing complexity of a part. Opportunistic process planning can remedy this drawback. The approach consists of dividing the features into two sets : one set, called the important features, are used to generate a process plan; the other features, called non-important features, are added to the process plan afterwards. This generation method resembles much the reasoning pattern of a human process planner. The developments are carried out in the framework of the ongoing Esprit project 6805 COMPLAN. Other reasoning methods, used in the project and described in this paper, are : combined variant/generative planning, non linear process plans, Petri nets, and feature based reasoning.

Factor Analysis and Predictive Validity of Microcomputer-Based Tests

11 tests were selected from two microcomputer-based performance test batteries because previously these tests exhibited rapid stability (< 10 min. of practice) and high retest reliability efficiencies ( r> 0.707 for each 3 min. of testing). The battery was administered three times to each of 108 college students (48 men and 60 women) and a factor analysis was performed. Two of the three identified factors appear to be related to information processing (“encoding” and “throughput/decoding”), and the third named an “output/speed” factor. The spatial, memory, and verbal tests loaded on the “encoding” factor and included Grammatical Reasoning, Pattern Comparison, Continuous Recall, and Matrix Rotation. The “throughput/decoding” tests included perceptual/numerical tests like Math Processing, Code Substitution, and Pattern Comparison. The output speed factor was identified by Tapping and Reaction Time tests. The Wonderlic Personnel Test was group administered before the first and after the last administration of the performance tests. The multiple Rs in the total sample between combined Wonderlic as a criterion and less than 5 min. of microcomputer testing on Grammatical Reasoning and Math Processing as predictors ranged between 0.41 and 0.52 on the three test administrations. Based on these results, the authors recommend a core battery which, if time permits, would consist of two tests from each factor. Such a battery is now known to permit stable, reliable, and efficient assessment.
