Abstract

This study aims to explore pre-service physics teachers’ problem-solving skills through the implementation of problem solving virtual laboratory (PSVL) model on the concept of simple pendulum. This research has been conducted at a university in Bengkulu in academic year 2016/2017. This research is a quasi experiment with nonequivalent control group design. Subjects were 70 students divided into experimental and control groups. Students of the experimental group follow lab activity using PSVL model, while the control group used the expository virtual lab (EVL) model. Students’ problem-solving skills are explored using problem-solving skills tests. Based on the data analysis, it is found that the improvement of students’ problem solving skills of experimental group and control group differ significantly. Improved students’ problem solving skills in experiment group was higher than control group. It can be concluded that the implementation of the PSVL model can improve students’ problem-solving skills.

Abstract

Identification has been carried out to get an overview of the student's Level conceptual change of K-11 student on the hydrostatic pressure concept using Virtual Conceptual Change Laboratory (VCCLab). The VCCLab was created to accomplish the conceptual change level of students’ construction and reconstruction. This investigation aimed to decide the degree of students’ applied change identified in the concept of hydrostatic pressure by involving in VCCLab activities. The strategy utilized was a quantitative enlightening technique which was conducted on a day and a half at class XI-one of the senior high school in West Java Province. The level of students’ conceptual change was identified by using a diagnostic test in the Four - tier test (FTT) format and the results of the students’ worksheets were analyzed based on the guidelines for determining the level of conceptual change. Conceptual change level consists of 1) Scientific conception from the beginning (SCFB); 2) Static (S); 3) Reconstruction (R); 4) Construction (C); and 5) Disorientation (D). The results of the research with VCCLab showed that level 1) scientific conception from the beginning (SCFB) is around 11.1%; 2) Static (S) is around 5.55%; 3) Reconstruction (R) is around 66,7%; 4) Construction (K) is around 16,7% and Disorientation (D) is 0%. In line with the results obtained, it is known that VCCLab can remediate missconception and reach the degree of calculated change in students’ construction and reconstruction.

Abstract

Research on the effectiveness of collaborative problem-solving using decision-making problems in improving pre-service physics  teachers’ thinking skills has been carried out. This research aims to find out the effectiveness of the application of collaborative problem-solving using decision-making problems to improve the pre-service physics teachers’ critical thinking skills. The method used was pre-experiment with one group pretest-posttest design. The research subjects were 76 pre-service physics teachers at a university in the city of Makassar, South Sulawesi. An essay test of critical thinking skills was employed to collect the data that 6 items. The results showed that after implementing collaborative problem-solving using decision-making problems, students' critical thinking skills increased to high category, and most of the students’ critical thinking skills improvements are also categorized as high. Thus, collaborative problem-solving using decision-making problems is effective to improve the pre-service physics teachers critical thinking skills.

Abstract

Telah dilakukan proses optimalisasi struktur sel surya GaAs sambungan p-n melalui perhitungan secara analitik, dengan variabel perhitungan meliputi makeup divais seperti ketebalan lapisan-lapisan semikonduktor dan konsentrasi doping ketakmurnian, serta parameter parameter divais seperti waktu hidup pembawa muatan minoritas, koefis'en difusi pembawa muatan minoritas, dan laju rekombinasi permukaan. Parameter-parameter divais telah diambil dari data-data hasil eksperimen, hasil simulasi, maupun dari hasil kajian teoretik. Kehadiran lapisan anti refleksi yang tergandeng dengan lapisan window AlGaAs dalam perhitungan ini diwakili dengan nilai transmisivitasnya. Kriteria struktur sel surya optimum ditentukan berdasarkan tingkat pencapaian rapat photocurrent yang optimum.Hasil perhitungan menunjukkan bahwa kehadiran lapisan anti refleksi yang tergandeng dengan lapisan window AIGaAs dapat meningkatkan rapat photocurrent yang dapat dibangkitkan sel surya GaAs secara signifkan. Dibanding dengan bahan lapisan anti refleksi lain, sistem MgFWnS dapat membangkitkan rapat photocurrent paling besar jika dipasang pada sel surya GaAs. Struktur optimum sel surya GaAs terjadi ketika bahan lapisan anti refleksi terbuat dari MgFyZnS, ketebalan lapisan window (AIGaAs) sebesar 20 nm, ketebalan lapisan tipe-p dan tipe-n berturut-turut sekitar 1,5 fan dan 3,5 fan, serta konsentrasi doping akseptor di tipep (N,4) dan konsentrasi doping donor di tipe-n (ND) berturut-turut sekitar 1 x 1018 cm-j, dan 1 x 10" cm-3 . Dengan struktur seperti itu dapat dibangkitkan rapat photocurrent optimum sekitar 46,5 mAlcm2 .

Abstract

This study aims to see how well Android based multi-representation test to profile 4C skill  based on experimental activities on heat transfer topic regarding gender and learning styles    A descriptive research to profile  the 4C skill students based on gender and learning style. We use fleming’s VAK learning style questionnaire to identify student learning styles. The research subjects were 60 students of class XI MIPA at a public high school in Majalengka Regency, consisting of 20 male students and 40 female students. 33 students (7 boys and 26 girls) had an Auditory learning style, 17 students (8 boys and 9 girls) had a visual learning style and 10 students (5 boys and 5 girls) had a visual learning style. kinesthetic. Research data were analyzed using quantitative descriptive analysis techniques. The results showed that female students have higher 4C skills than male students in each student’s learning style. This result is agreed with previous research.  The visual learning style both female and male student have the higher 4C skill than other learning style and agreed with previous results. It can be understood since the application is dominant with visual content. We conclude that Android based multi-representation test has successfully measure 4C skills based on experiment activities. Teachers think that the  application has complete features to measure 4C’s students. It is practical tool to get student’s 4C’ profiles easily and quickly.  Based on 4C’s students profile have successfully gave feed back for teacher to improve   their learning design such as inserting group experiment activity to solve problem. We conclude that Android based interactive test can be an alternative test for profiling Student’s 21st century skill quickly, easily and practically.Keywords: 4c profile, android based multi-representation test, gender and learning style
