Abstract

 AbstractThis research aims to reveal profile, the  percentage and find out the causes of students having difficulty in solving about work and energy. Research conducted at SMPN 12 Pontianak with research subjects wAere 73 students. Data collected by the test essay and interviews. The analysis data technic that did was Miles and Huberman. The results show that students' difficulties are divided into 5 according to the Heller problem solving stages. (1) Difficulty of visualize the problems experienced by students was 95.62%. The cause is because students do not know to draw sketches on the problems. (2) The difficulty of physics description experienced by students was 55.06%. The cause is lack of understanding of the problem given. (3) The difficulty of the plan a solution experienced by students was 47.12%. The cause is lack of understanding of the concept used. (4) While the difficulty of execute the plan experienced by students was 52.06%. Because it is wrong to write down and be asked, it causes students to have difficulty carrying out the plan. (5) And difficulties check and evaluate was 53.43%. The cause is because the students are less careful in checking the answers.Keywords: analysis difficulty, problem solving Heller, work and energy

Abstract

AbstractThe aim of this research is to determine the effectiveness of Think Pair Square (TPSq) learning model application assisted by animation in remediating students? misconception about rotational dynamics in Grade XI MAN 2 Pontianak. Method of research that is used is pre-experimental design with one group pre-test post-test design. Data was collected by using multiple choice test which consists of three alternative choices completed by reasons with 8 questions. The sample of this study is 36 students of XI IPA 1 which are chosen randomly by using Intact Group technique. Based on data analysis, the average of misconception?s reduction percentage that is got is 44.44% in each concept. Based on Mc Nemar test calculation and continued by Chi Squared test, identified that the average value of , with an average value of  = 26.57. It means that there is significant change of misconception in rotational motion concept. Based on the effect size calculation, the score of ES = 0,485 (medium categorized). Therefore the using of Think Pair Square learning model assisted by animation can remediate student?s misconception about dynamic effectively.Hopefully this study can be used as an alternative to remediate student?s misconceptions. Keywords: Misconception, Think Pair Square, Animation

Abstract: This research was intended to create interactive multimedia  with multirepresentation approach to gain study result of student class X MIPA at SMA Negeri 7 Pontianak on the concept of Archimedes theory equipped with using manual. The method of research that was applied in this research was developmental research with procedural model which referred to research and development of Borg and Gall. There were 62 students of class X MIPA SMA Negeri 7 Pontianak who took part in this research. The study result of concept of Archimedes theory was shown by the increasing numbers of students who could solve problem related to Archimedes theory. The problem solving was shown by giving test about concept of Archimedes theory to students to be done precisely. The concept of Archimedes theory used in this research was comparing the mass of an object in the air and water, sinking event, floating event and flying event. Based on the research result there was significant increasing of study result of students in doing test for all indicators, that was 53.45%. In conclusion, interactive multimedia with multirepresentation approach was effective to decrease the numbers of students who could not solve problem on the concept of Archimedes theory. Keywords: development, interactive multimedia, multirepresentation, study result, Archimedes theory Abstrak: Penelitian ini bertujuan untuk menghasilkan multimedia interaktif pendekatan multirepresentasi untuk perolehan belajar pebelajar kelas X MIPA di SMA Negeri 7 Pontianak pada konsep hukum Archimedes dilengkapi dengan buku panduan penggunaannya. Metode penelitian yang digunakan yaitu penelitian pengembangan dengan model prosedural dengan berpedoman kepada penelitian dan pengembangan Borg and Gall. Sebanyak 62 pebelajar kelas X MIPA SMA Negeri 7 Pontianak berpartisipasi dalam penelitian ini. Perolehan belajar konsep hukum Archimedes ditunjukkan dengan semakin banyaknya pebelajar yang dapat memecahkan masalah-masalah berkaitan dengan hukum Archimedes. Pemecahan masalah ditunjukkan dengan cara memberikan soal-soal konsep hukum Archimedes untuk diselesaikan dengan betul oleh pebelajar. Konsep Hukum Archimedes yang digunakan yaitu membandingkan berat benda di udara dan di air, peristiwa tenggelam, peristiwa mengapung dan peristiwa melayang. Berdasarkan hasil penelitian terjadi perubahan perolehan belajar pebelajar yang signifikan dalam menyelesaikan soal untuk semua indikator soal tes, yaitu sebesar 53,45 %. Dengan demikian, multimedia interaktif pendekatan multirepresentasi efektif untuk mengurangi jumlah pebelajar yang tidak dapat memecahkan masalah pada konsep hukum Archimedes.   Kata kunci: Pengembangan, Multimedia Interaktif, Multirepresentasi, Perolehan Belajar, Hukum Archimedes

Abstrak:Penelitian ini bertujuan untuk mengetahui penurunan jumlah siswa  yang mengalami miskonsepsi pada materi tekanan setelah diremediasi di SMP Negeri 20 Pontianak menggunakan strategi quantum teaching dengan kerangka TANDUR. Bentuk penelitian yang digunakan adalah pre-eksperimental design dengan rancangan one-group pretest-posttest design. Alat pengumpul data berupa tes diagnostik berbentuk two tier test yang terdiri dari 6 soal. Penelitian ini melibatkan 31 orang siswa kelas VIIIF sebagai sampel yang dipilih dengan teknik intact group. Berdasarkan hasil bentuk miskonsepsi siswa tertinggi saat pre-test yaitu pada hukum Archimedes (48,38%). Sedangkan bentuk miskonsepsi siswa tertinggi saat post-test yaitu pada tekanan hidrostatis (45,16%). Dari hasil perhitungan rata-rata jumlah persentase penurunan jumlah siswa yang mengalami miskonsepsi sebesar 1,61%. Strategi quantum teaching dengan kerangka TANDUR diharapkan dapat digunakan sebagai alternatif untuk meremediasi miskonsepsi yang dialami siswa.
