Abstract

AbstractThis study investgated the effectiveness of instructional model Engage, Explore, Explain, Extend (4Ex2) to reduce the number of students who have misconceptions on simple harmonic motion at MAN 2 Pontianak. This research is pre-experimental research with one group pre-test post-test design with a total sample of 36 students from class XI MIA 2. The diagnostic test which consist of 10 multiple choices with open reason used to identification student’s misconception. Based on the analysis of diagnostic data using the McNemar test, there was a significant students conceptual change (x2count = 15,75; df = 1; ) after instruction. The use of Instructional Model 4Ex2 effective to reduce the number of students who are misconceptions in medium category (< g > = 0,63). This research is expected to be used as alternative remediation activities to reduce misconceptions in a learning processKeywords: Miskonsepsi, Model Instruksional 4Ex2, Getaran Harmonis

Abstract

AbstractThis study aimed to analyze students ability to solve Higher Order Thinking Skills (HOTS) problems in physics, especially in simple harmonic motion in SMA Kristen Immanuel Pontianak. The methods used in this research was descriptive method with qualitative approach. The subjects in this research is 60 students of class XI MIPA. The data-collecting instruments in this research was ten essay problems, consists of  analyze, evaluate, and create step of thinking. According to the data result of this research, it is concluded that the students ability to analyze problems 43,13%, while the average of stdents evaluate ability are 41% and students create ability are 12.67%. The result of mann-whitney were asymp. Sig. (2-tailed) score of 0,075 (>0,05), so H0 are accepted and H1 are denied. It means that there aren't significant difference between the average of the result of students problem solving abilities of male and female students. Those results show that students abilities of solving high order thinking problems still categorised as low. Therefore, the remediation of  learning activities in class still needed in order to increase students high order thinking skill in SMA Kristen Immanuel Pontianak. Keyword: Analysis, Higher Order Thinking Skills, Simple harmonic motion

Abstract

AbstractIn this study, the effect of conceptual change text (CCT) with PhET simulation to remediate students? misconceptions of fluid dynamic at SMA was investigated. Quasi-experimental with non-equivalent control group design was used which involved 62 eleventh grade students. This study was made of into two groups. Experimental group (N=29) were given CCT with PhET simulation, whereas the control group (N=33) were given re-test. Nine open-ended multiple-choice questions concerning fluid dynamic were used as data collection tool. The results showed experimental group?s average of decreasing students? misconceptions (59,58%) were higher than control group (15,57%), and caused differences between both of groups that were proved by two-sample proportions test, Zscore (2,08) > Ztable (1,96). In the other hand, decreasing quantity of that misconception (DQM) value showed CCT with PhET simulation more effective than re-test to remediate students? misconceptions about fluid dynamic. It determined that CCT with PhET simulation could be alternative to remediate students? misconceptions. Keyword: Remediate, Misconception, CCT, PhET Simulation, Fluid Dynamic

Abstract

AbstractThis research aimed to remediate student?s misconceptions used Flipped Classroom model on Impulse and Momentum subject in Senior High School 7 Pontianak. This research used experiment method with pre-experimental design form and used Nonequivalent Control Group design. This sample used Nonprobability sampling technique, in which the outcome was class of XMIA 4 and XMIA 5 with total 64 students. The instrument of this research was a diagnostic test consist of 12 multiple choice questions with open reasoning. Based on the data analysis, the average percentage of student's misconception decreased from 86% to 30.5% after implemented Flipped Classroom model. The Two Proportion statistic test result with Zformula > Ztable (4.00 > 1.96) this result showed there was a significant difference between the two class. It showed that Flipped Classroom be able to decreased student?s misconception. The researcher hopes this model will be used as an alternative teaching physics remediation to student's misconceptions. Keywords: Flipped Classroom, Impulse and Momentum, Misconceptions,  Remediation,

Abstract

AbstractThis study was quasi experimental design with nonequivalent control group design. The effectiveness of systematic approach to problem solving in improving students’ ability to solve the rotational dynamics problem in SMAN 2 Pontianak was investigated. 120 students selected used intact group and randomly, obtained 30 students in XI MIA 3 class as the experimental group was taught by using systematic approach to problem solving and 30 students in XI MIA 2 class as the control group was taught by using formal education method. Essay test questions about rotational dynamics were used for data collection. The results of study reveal the average score of experimental group increased from 32.5 to 68.1 and in control group increased from 35 to 54. T–test was used on this study with the significance of 5%. There were significant differences in problem solving abilities after being remediated using a systematic approach. There are also significant difference between experimental and control groups students’ posttest scores. Systematic approach to problem solving can effectively improve students' ability to solve problems with effect size of 3.04. This study is expected to be used as an alternative learning for students who have difficulty in solving problems especially in physics. Keyword: Systematic approach to problem solving, Students’ Ability, Rotational Dynamics

Abstract

The aim of this research is to characterize impedance, capasitance and relative permitivity of the characteristics of electric thin film ZnS and ZnS:Mn. This research was started from making thin film with different deposition speed and with thermal co-evaporation method in vakum tubes.  The estimation is the characteristics of thin film ZnS impedance and ZnS:Mn was done outside this vacum with various frequency between thousaund to million hertzs, with different deposition speed and the same thickness. Defining impedance of ZnS thin film wich the most optimal frequency would influence capasitance and relative permittivity of the thin film on the characteristics of the electricity. Besides, capasitance and resitance values of ZnS:Mn thin film would change if given different Mn portion on that thin film. From the result of the research, it could be identified as follows. On the area of the thousand to ten thousand Hertz, it was know is that relative permitivity/constante static dielectrics K(0) ZnS:Mn thin film was not the frequency function that it could be regarded as constant like K(o) = 10. The price of capasitance ZnS:Mn was increasing with less Mn amount in that thin film. The price of ZnS:Mn electric resitance is reduced with less Mn amount on  that thin film. Key words: Impedance, thin film ZnS:Mn, co-evaporation.

Abstract

AbstractThis research aims to determine the effectiveness of giving feedback in the form of answer sheet correction accompanied by teacher’s explanation to remedy the students’ mistakes in working on the material Newton's law of gravity in SMA Negeri 9 Pontianak. The research method used is Pre-Experimental design with one-group pretest and posttest design. Sampling was done by random sampling with intact group technique which the sample is 33 students of XI MIA 3. The tool of data is in the form of essays consists of 4 questions. The result shows that the largest students’ mistake in the pre-test is on writing formula and calculating which 125 errors. After doing remediation and post-test activities become 36 and 45 errors. However the smallest mistake is writing known and asked which 106 errors. After doing remediation and post-test activities become 30 errors. The number of average decrease in students’ mistake on the material Newton's law of gravity after given remediation by giving feedback in the form of answer sheet correction with teacher's explanation is 69.5%.Providing feedback in the form of answer sheet correction accompanied by teacher’s explanation is effective to remedy the students’ mistake with proportion 0.69 which is moderate. Giving feedback in the form of answer sheet correction accompanied by teacher’s explanations can be used as an alternative way in remediating students’ mistake on the material Newton's law of gravity.   Keywords: Answer sheet Correction, Newton's Law, Mistakes
