Development of Two-Tier Multiple Choice Question Assessment Instruments for Measuring Science Process Skills Regarding Global Warming

摘要

Psychomotor has many indicators, psychomotor indicators owned among students vary so that there needs to be improvements associated with psychomotor students. Psychomotor indicators have in common with the indicators contained in the ability of the science process skills, so that each student can improve psychomotor ability by improving the ability of the science process skills owned. In this study to measure the ability of science process skills that students have to use the instrument of evaluation of Two-Tier Multiple Choice Question, so the purpose of this research is to know the feasibility of Two-Tier Multiple Choice Question instrument to measure the ability of science process skills in junior high school students. This research uses research and development which is the learning evaluation instrument, by combining global warming science materials with the indicators in the ability of the existing science process skills. Implementation of this research was conducted by involving three schools is SMP N 1 Tasikmadu, SMP N 3 Karanganyar, MTs N Karangmojo. Based on the results of this study obtained the difficulty level about 44% easy and 56% medium category for first tier and 36% easy and 64% medium category for second tier. While for feasibility test of two tier multiple choice question evaluation instrument for first tier 40% enough and 50% good stated, while for second tier 44% enough and 56% good stated. From these two conclusions, it can be concluded that the Two Tier Multiple Choice Question evaluation instrument used is appropriate for use in learning.
