Identification of students’ science process skills in Basic Physics Practicum II in using e-module

Abstract

Good science process skills demonstrated by the attitude of students in conducting experiments in the laboratory. This study aims to determine the mastery of science process skills of students of Physics Education in Universitas Jambi, both students who use the printed Guidebook and students who use the e-module as guide in practicum activities by reviewing eight aspects of integrated science process skills. This study uses a quantitative approach with experimental research methods, namely true experimental. In the study sample used was a student of Physics Education were divided into two groups, 35 students for experiment class and 30 students for control class. Assessment instruments used were observation sheet science process skills with a score of skills used in the form of Likert scale. Based on the analysis score mastery of integrated science process skills of students in the experimental class, operationally defining variables have the highest percentage of 51.4% to the category of very good, whereas in the control class, analyzing aspects of investigations has the highest percentage of 53.3% with a good category.

Description of student science process skills on temperature and heat practicum

“…The prediction skills indicator shows that students are in the good category with a percentage of 37.5%. Indicators of making predictions can be seen when students compare of the appearance of wax powder before, after heating, and after cooling (Lumbantoruan et al, 2019). In this study, it can be seen that these students can compare well what will happen to the candle before and after heating and cooling can be said to have good predictive skills.…”

“…The communication skills indicator shows that students are classified as not good with a percentage of 44.8%. The communication indicator can be seen when students discuss the measurement results with a group of friends, and students present the results of the measurement experiments (Lumbantoruan et al, 2019). However, in this study, students tend to be more passive when conducting experiments.…”

“…The indicators of measurement skills show that students are in the bad category with a percentage of 37.5%. The indicator of measuring can be seen when students take temperature measurements with a group of friends, reading the thermometer scale, and reading the time scale on the stopwatch (Lumbantoruan et al, 2019). However, in this study students are independent, meaning that they do not conduct experiments in groups.…”

“…Observation skills include skills using multiple senses, identifying differences and similarities of an object, using tools to obtain data, and searching for relevant data (Sahnaz et al, 2018). The indicator of observing can be seen when students observe the tools and materials used in an experiment about changing shape, observing the scale on the thermometer, observing the thermometer during measurements to determine the measurement results of the temperature of the wax powder during heating and cooling, observing the time required to do heating and cooling with a stopwatch, and students observe the data in the table to graph the relationship of variables in determining changes in the appearance of substances when heating and cooling (Lumbantoruan et al, 2019). This observation ability is more emphasized on practicing experimental thinking skills which include the administration of experiments by recognizing the equipment used in measurements both in the laboratory and outside the laboratory (Rusmiyati & Yulianto, 2009).…”

“…The indicator of classification can be seen when students classify the characteristics of experimental data changes in the form of substances during heating and cooling. Meanwhile, the level of success of students doing classification can be seen in making data tables (Lumbantoruan et al, 2019). If students cannot classify tools and materials during the practice, students will have difficulty in obtaining and processing data (Darmaji et al, 2018a).…”
