The study aimed to develop the Current Stick teaching aids and determine its effectiveness to improve students’ generic skills. The type of research is development research which involved 180 students of class X SMAN in Blora were chosen through cluster random sampling. The instrument used to collect the data was a validated question sheet from the assessment of students’ practicum report in using Current Stick teaching aids and the observation sheet. The instruments were addressed to students from the control class and experimental class. The obtained data were tabulated and analyzed by using t-test. The result shows that the experimental class achieved an average percentage of generic science skills of 77.2%, while the control class reached 66.4%. It reveals that the difference in the percentage of generic science skills is the result of using Current Stick teaching aids. Based on the results and discussion, it was found that the development of Current Stick teaching aid is effective to improve students' Generic Science skills.
One of the reasons for the lack of student learning motivation is the unavailability of learning media that can focus students' attention and help students understand science concepts. The purpose of this PKM activity is to provide assistance to science teachers in overcoming difficulties in the absence of learning media as a tool in the science learning process in junior high schools. The specific target of this PKM is to design, create and use virtual learning media for physics/science materials. The output of this activity is a physics/IPA learning media package for junior high schools. The method used in this activity is mentoring and training. Activities in this PKM are mentoring and training in designing, creating and using virtual learning media for junior high school physics/science materials. This activity was carried out for 32 hours of lessons and monitoring the use of learning media by MGMP physics/IPA teachers in Semarang Regency for 3 months. Activities that have been carried out to overcome partner problems are designing virtual learning media using several Power Point Presentation Developer software, Video Tracker, Latex and PheT. The series of activities consists of four main stages, namely media design, media creation, media use and testing of virtual learning media for junior high school physics/science materials. Junior high school physics/science teachers succeeded in making learning media using Power Point Presentation Developer and Phet on the concepts of temperature and heat
Abstrak: Penelitian ini bertujuan untuk mengetahui pengaruh pendekatan multirepresentasi terhadap kemampuan kognitif siswa dalam pembelajaran Fisika. Desain penelitian ini adalah True Experimental Design yang berbentuk Pretest-Posttest Control Design. Populasi dalam penelitian ini adalah 30 siswa kelas VII MTs NU Ma’rifatul Ulum. Sampel dalam penelitian adalah siswa kelas VII A sebagai kelas eksperimen berjumlah 15 siswa dan siswa kelas VII B sebagai kelas kontrol berjumlah 15 siswa. Instrumen penelitian yang digunakan adalah soal posttest yang disesuaikan dengan enam indikator Kemampuan Kognitif Siswa dan lembar keterlaksanaan pembelajaran. Berdasarkan analisis data diperoleh nilai pretest kelas eksperimen 35,47 dan kelas kontrol 26,4. Sedangkan nilai rata-rata posttest kelas eksperimen 63,47 dan kelas kontrol 38. Dari hasil pretest-posttest yang diperoleh dari kedua kelas tersebut menunjukkan bahwa ada pengaruh yang signifikan kemampuan kognitif siswa pada kelas eksperimen dibandingkan kelas kontrol. Analisis statistik menunjukkan nilai thitung 0,000 ttabel 0,05 dengan taraf signifikansi = 0,05, sehingga menolak H0 dan menerima Ha. Adanya perbedaan yang signifikan antara kelas eksperimen dan kelas kontrol maka pendekatan Multirepresentasi memberikan pengaruh terhadap Kemampuan Kognitif siswa dalam pembelajaran Fisika. Kata kunci: Pendekatan Multirepresentasi, Kemampuan Kognitif Siswa.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
