PENGEMBANGAN ALAT PRAKTIKUM KEPOLARAN DI SMA MUHAMMADIYAH 1 PONTIANAK

Methods applied in schools have not been able to make students understand the sub-material of polar and nonpolar covalent compounds. One of the success factors of the practicum method is the use of the right practicum tools. Therefore, it is necessary to develop practical tools to make it easier for students to understand the concepts of polar and nonpolar covalent compounds. This study aims to produce a polarity and practicum tool on sub-material polar and nonpolar covalent compounds that are valid, practical, and effective. Validity is measured from the validator's assessment on material aspects and media using a validation sheet. Practicality is measured using teacher and student response questionnaires. Effectiveness is measured by the results of students' Pretest and Postest. This type of research is the development of the ADDIE Research and Development (R & D) model (Analysis, Design, Development, Implementation, and Evaluation). The results of the analysis show that the polarity practicum tool developed from the material and media aspects was stated to be very valid with an average validity value of 0.83 and 0.89, respectively. The practicality test results obtained very practical criteria with a practicality value of 96.64%. The aspect of effectiveness using the N-Gain value in the field trial results obtained N-Gain values of 0.72 with very high criteria. Thus, the polarity practicum tool developed is suitable for use as a sub-material learning media for polar and nonpolar covalent compounds.

PENGEMBANGAN ALAT PRAKTIKUM GERAK JATUH BEBAS MENGGUNAKAN SENSOR PHOTOTRANSISTOR UNTUK PEMBELAJARAN FISIKA PADA MATERI GERAK JATUH BEBAS

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.

Elementary School Teachers' Perceptions of Science Practicum During the Limited Face-to-Face Learning Period

This research aims to describe elementary school teachers' perceptions of science practicum during the limited face-to-face learning period at State Elementary School 182/I Protected Forest in understanding teachers' perceptions of science practicum during the limited face-to-face learning period. This research was conducted at State Elementary School 182/I Protected Forest. Research data was obtained by conducting interviews with class teachers who implemented science practicum (as main data) carrying out documentation (as supporting data). After conducting interviews and documentation, the data was analyzed qualitatively using Miles and Huberman data analysis. The results of this research indicate that primary school teachers' perceptions of science practicum during the face-to-face learning period are limited, first of all, absorption of stimuli or objects from outside the individual. Science practicum teachers gain knowledge or information from several sources such as teacher books, student books, practice books, the internet and YouTube. Second, for understanding science practicum, the teacher understands science practicum using existing sources, from these sources he can understand the meaning of science practicum, the science practicum tools and materials used, and the steps for science practicum. The third is assessment or evaluation of science practicum. From the teacher's responses there was a positive assessment of the science practicum. The conclusion obtained from this research is that the teacher's perception of science practicum during limited face-to-face learning can be seen from the teacher's response, from absorption of stimuli or objects from outside the individual, understanding or understanding and assessment or evaluation.
