Abstract:There is no learning media yet except experiment modul on experiment subject that cause the lack on students science process skill. As Abstrak: Belum adanya media pembelajaran selain modul praktikum cetak pada mata kuliah eksperimen fisika menyebabkan kurangnya keterampilan proses sains mahasiswa. Hal ini mendorong peneliti untuk melakukan sebuah pengembangan media pembelajaran berupa video tutorial pada mata kuliah eksperimen fisika. Tujuan penelitian ini adalah untuk mengetahui praktikalitas dari video tutorial pada mata kuliah eksperimen fisika untuk meningkatkan keterampilan proses sains mahasiswa. Jenis penelitian ini adalah penelitian pengembangan (research and development). Hasil video tutorial yang telah divalidasi dilakukan uji coba terbatas kepada mahasiswa semester VII Jurusan pendidikan Fisika IAIN Batusangkar. Berdasarkan hasil angket respon juga diketahui bahwa video tutorial pada mata kuliah eksperimen fisika untuk meningkatkan keterampilan proses sains mahasiswa sangat praktis digunakan. © 2017 Pendidikan Fisika FTK UIN Raden Intan LampungKata kunci: eksperimen fisika, keterampilan proses sains, video tutorial.
This research was done because of the students' difficulties in understanding the concept of global warming and implementing character values so that it needed to design poster media based character education. This research was aimed to see the effectiveness of poster media based character education that was already developed in Ilmu Alamiah Dasar subject. The design of the research was a research development. The effectiveness of poster media was gotten from testing to the students who had conducted Ilmu Alamiah Dasar subject. The instrument of the research was questionnaire. The result of the rsearch showed that developing poster media based character education was very effective according to the students with percentage 81.9%.
This study aims to produce free fall practicum tools by utilizing phototransistor sensors to record the travel time of objects that fall from the starting point to the end point. Dealing with free falling equipment (GJB), equipment in schools is generally still very simple that is using a stopwatch. This type of research is a research and development using 4-d model (define, design, develop and disseminate), which is limited to the stage of development to practicalization activities. Data were collected through validation and responses toward administered questionnaires. Data analysis were conducted by analyzing validation sheet and quantitative response questionnaire by finding percentage of each item on the validation sheet. Then the data validation results are analyzed by descriptive technique to describe the quality of the developed product. The result of calibration of free fall practicum by using phototransistor sensor at 40 cm, 50 cm, and 70 cm distance obtained the average travel time of each object is 0.28 s, 0.32 s, and 0.37 s. These results indicate that the practicum tool has been calibrated. Validation of practicum tool is 72,39% and validation of questionnaire response of practican is 75%, indicating tool categorized valid. Furthermore, this tool is tested in class X.MIA and XI.MIA MAN 3 Payakumbuh which consisted 23 students in the science laboratory of MAN 3 Payakumbuh with the questionnaire response practicality are 87.75% and 84.41% respectively which are categorized very practical.
Abstractlimitations on the hard module and the lack of availability of technology-based learning media led to a lack of student motivation in learning physics. As a result, it is necessary to develop a constructivism-based electronic physics module. The objective of this research is to know the validity of constructivism-based electronic physics module for 1st student in Senior high school. This research is research and development research. Feasibility tests of the electronic module are carried out through the validation. Validation was carried out by three validators. Based on validation, it showed that constructivism-based electronic physics module that was developed is very valid with a percentage of 89.08%.AbstrakKeterbatasan pada modul cetak serta kurangnya ketersediaan media pembelajaran yang berbasis teknologi menyebabkan kurangnya motivasi siswa dalam mempelajari fisika. Untuk itu perlu dikembangkan sebuah Modul Elektronik fisika berbasis konstruktivisme. Penelitian ini bertujuan untuk menghasilkan Modul Elektronik Fisika yang valid untuk siswa Kelas X SMA. Penelitian ini adalah penelitian pengembangan (research development) dengan menggunakan model 4-D. Pada tahap develop dilakukan pengembangan modul dengan divalidasi oleh 3 orang validator. Berdasarkan hasil validasi terhadap modul elektronik fisika berbasis konstruktivisme yang dikembangkan adalah sangat valid dengan persentase 89,08%.
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.
