Development of Experiment Performance Assessment Instruments using Guided Inquiry Learning Models to Assess Science Process Skills

Abstract

This study aims to produce an experimental performance assessment instrument with guided inquiry learning model, prove the validity and estimate the reliability of instrument products, and determine the effectiveness of instruments to improve process performance. The method used is R & D (Research and Development) adopted from Dick et al which is divided into preliminary stage, planning stage, development stage, limited trial stage and extensive trial stage. Based on the results of the trial, the reliability of the rating results of the assessment instrument of science process skills were 0.707–0.989. The t-test results show that there is an improvement of science process skills. The results of this study are: (1) an experiment performance assessment product for science lesson of junior high school material of light properties, shadow formation, and working principle of optical instrument; (2) the experiment performance assessment instrument product has valid and reliable categories for assessing science process skills; (3) an effective experiment performance assessment instrument to improve science process skills.

Development of Physics Learning Instrument using Guided Inquiry Model as Effort to Increase Student Learning Result on Dynamic Fluid Learning Material at Senior High School

“…The results of the validation of learning devices are shown in Table 1. This research is conducted on the results of Srirahayu and Arty [14] regarding the development of physics tools with guided inquiry models, which show that the learning tools developed using the guided inquiry model are in the Highly Valid category according to the criteria of content validity and construct validity. Content validity shows that the learning tools developed are based on the curriculum.…”

“…According to Vanags et al [13], the inquiry learning model is oriented on process and expertise to conduct research. Srirahayu and Arty [14] stated that guided inquiry could assist the student to practice within a team, developing competency in research, knowledge, motivation, writing ability, cooperative learning, and social skill. Through guided inquiry, students are expected to discover certain new concepts or knowledge through hands-on-activity process.…”

A mathematical anxiety scale instrument for junior high school students

“…It means that 75.6% of the observed score variance resembles the true score variance. According to the literature, the reliability value of 0.756 indicates that the instrument has good reliability [22][23][24][25]. Thus, the instrument which was developed can be said to have good reliability.…”
