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%.

This study aims to see the effect of the gallery walk method application to the attitudes and activeness of the students. The research data was obtained through quasi-experimental research by using randomized subjects posttest only controlled group design. This research was conducted at VIII grade students of MTsS Darussalam Sitiung 1 Islamic Boarding School Dharmasraya Regency which consisted of 2 classes with a population of 50 students. Samples were selected by simple total sampling technique, where the experimental and the controlled class were selected by lotting method. Data collection was carried out using observation and data analysis techniques through statistical tests consisting of normality, homogeneity and hypothesis tests with a significance level of 5%. Data from the hypothesis using the t test shows that the tcounted for the formation of attitudes, and activeness is 3.21 and 2.16, respectively with v = 48. Based on these values it is known that tcounted> ttable for the attitudes and activeness of students, namely (3.21> 1.677), and (2.16> 1,677) at the 5% significance level. Thus the hypothesis Ho is rejected and H1 is accepted, where the formation of the attitudes and activeness of students using the gallery walk method is better than using conventional learning with a certainty of 95%.
