Isomorphic Test Of Newton’s Third Law For Investigating Students’ Scientific And Representational Consistency

We have developed a set of isomorphic test for investigating scientific and representational consistency in the context of Newton’s Third Law. The test consisted of 30 multiple-choice items concerning five central force contexts: gravitation, electrostatics, magnetic, pushing, and crashing (impulse force). The test items were designed using various representations (i.e., verbal, diagram/vectorial and graphical). Before we conducted try out, test draft was reviewed by two physics content and evaluation experts for knowing appropriateness of concepts and isomorphic aspect of the test. We provide some evidence for analyses of the test based on the classical test theory. The limitation of the test is presented in this paper. Keywords: isomorphic test, Newton’s third law, scientific consistency, representational consistenc

Analisis Kemampuan Kognitif Siswa Kelas VII SMP Negeri 19 Palu dalam Pembelajaran Fisika pada Materi Kalor

The cognitive aspect is the main aspect in the educational curriculum and is a benchmark for assessing children's development which refers to the process of knowing as well as to the knowledge itself. This study aims to describe the cognitive abilities of 7th graders of SMP Negeri 19 Palu in learning physics on the topic of heat. This research is a qualitative research with a case study design. Data were obtained through student answer sheets in the form of cognitive ability tests and interviews. Based on the results of the students' cognitive ability tests of achievement at the level of analysis C1, C2 and C3, it shows that the cognitive abilities of students have achieved 54% which was still in the moderate category. The results of the analysis of test data for cognitive aspects of C1 were 74%, for cognitive aspects of C2 were 62%, and for cognitive aspects of C3 were 42%. In other words, the cognitive abilities of 7th grade students of SMP Negeri 19 Palu in learning physics on the topic of heat on each cognitive aspect are significantly different

Describe the Motivation and Learning Outcomes of Grade Sixth Students of SD Inpres 2 Lasoani on Science Learning through the use of Science Kit SEQIP Model.

The purpose of this study is to describe the motivation and learning outcomes of grade sixth students of SD Inpres 2 Lasoani on science learning through the use of science Kit SEQIP model. The method used is classroom action research method with two cycles. Each cycle consists of two meetings. The result of the first meeting at the first cycle are that the observation on activity of students scored 68%, are in the category enough, the student's classical absorption rate of 72%, students' classical completeness 47% and student learning motivation 62% are in enough category. The result of the second meeting at the first cycle are that activity of students scored 78%, is in good category, students' classical absorbency 79%, student's 72% classical learning completeness and 75% student learning motivation are in good category. The result of the first meeting at the second cycle are that the observation on activity of students scored 80% value, is in good category, students' absorbency 83%, student 89% classical learning completeness and student learning motivation 82% are in good category. The result of the second meeting at the second cycle are that the observation on activity of students scored 91% value, is in very good category, classical student absorbency 89%, 97% student learning completeness and student learning motivation 92% are in very good category. In conclusion the use of science Kit SEQIP model on science learning can improve the motivation and learning outcomes of students in grade sixth SD Inpres 2 Lasoani

Analysis of Student's Kinesthetic Activities Against Understanding the Principles of DSSC Work

This study aims to determine how students 'kinesthetic learning activities on understanding the DSSC work principles and to determine the effect of students' kinesthetic activity processes on understanding the working principles of DSSC at Tadulako University. This research was a descriptive-qualitative study where all data is collected based on facts obtained in the field to produce descriptive data in the form of written or spoken words from the people being observed. Respondents involved in this study were 42 students. Data obtained through activity activities, interview comprehension tests, and questionnaires. The results showed that students had been learning kinesthetic activities very well, through kinesthetic activities students became more active students and felt happy. This was reinforced by active discussion, test results where most students got good grades, and interviews. It can be seen that although students' learning styles differ if the kinesthetic learning style was applied, students can easily remember and understand if they do this directly, this was reinforced by a questionnaire. The information obtained by kinesthetic learning styles complements learning styles in addition to kinesthetic. &nbsp

The Effect of Logic Concept Cognitive Development on Physics Science Learning Achievement with Problem Solving Approach of the Eighth Grade Students of SMP Negeri 16 Palu

This research aims to find out the effect of logic concept mastery by cognitive development on physics science learning achievement with a problem-solving approach.

ANALISIS KOHERENSI KONSEP HUKUM NEWTON PADA SISWA KELAS X SMA NEGERI 5 PALU

Tujuan penelitian ini adalah untuk menganalisis koherensi konsep hukum Newton pada siswa kelas X SMA Negeri 5 Palu. Subyek penelitian ini terdiri dari 18 orang siswa SMA Negeri 5 Palu Kelas X. Data diperoleh dari tes koherensi konsep hukum Newton dan wawancara langsung. Tes terdiri dari 3 teori dasar hukum Newton yaitu hukum Newton I, hukum Newton II dan hukum Newton III, tiap-tiap hukum terbagi atas 2 tema berbeda dan setiap tema dibuat 3 soal dengan representasi berbeda yaitu representasi verbal, grafik dan diagram sehingga jumlah soal keseluruhan adalah 18 butir soal. Data penelitian dianalisis melalui pendekatan deskriptif kualitatif. Skor hasil tes kemudian dikelompokan menjadi 3 kategori yaitu kategori tinggi, sedang, dan rendah. Masing-masing dari kategori, diambil 2 siswa perwakilan untuk diwawancara guna menggali informasi yang lebih mendalam.  Hasil penelitian menunjukan bahwa tingkat koherensi konsep hukum Newton siswa menghasilkan rata-rata poin keseluruhan siswa 0,43 dengan poin  tertinggi 0,83 dan terrendah 0,17 yang masih lebih rendah dibawah harapan. Siswa masih lemah dalam menjawab soal tes dengan representasi grafik dan verbal. Perlunya pembiasaan oleh siswa dalam menyelesaikan persoalan dalam suatu konsep fisika dengan menggunakan multi representasi yang beragam guna memperbaiki koherensi konsep yang dimiliki siswa  terutama koherensi representasi.
