Abstract

This research aimed at knowing the quality of test item derived from its validity, reliability, difficulty level, discriminator power, and distractor effectiveness. Quantitative descriptive method was used in this research. Interview and documentation were the techniques of collecting the data. The data source used was in evensemester exam questions that were in the forms of multiple-choice, student answer sheet, and answer key. Anates 4.0.9 program was to analyze the quality of test items. The research findings of the analysis of multiple-choice test item quality on semester final exam of Chemistry subject at the eleventh grade of State Islamic Senior High School 2 Kepulauan Meranti showed that in the validity analysis there were 6 valid test items (17%) and 29 non validitems (83%); in the reliability analysis it was obtained the reliability score 0.955; in the difficulty level analysis there were 12 easy test items (34%), 17 medium items (49%), and 6 hard items (17%); in the discriminator power analysis there were 4 very good test items (11.5%), a good item (3%), 19 items (54%) that should be revised, and 11 items (31.5%) that should be eliminated; in the distractor effectiveness there 26 very good options (19%), 10 good options (7%), 25 poor options (18%), 55 bad options (39%), and 24 very bad options (17%). Therefore, it could be concluded that the quality of test items could be stated bad.

Abstract

This research aimed at knowing whether there was or not student misconception and its percentage on acid base using Four-Tier diagnostic test materials.

The subject of this research was the XI grade of science students of senior high school PGRI Pekanbaru. Observation, FourTier diagnostic tests, interview and documentation techniques were used for collecting the data. The findings of this research showed that there was misconception on acid base material (55%). The misconception happened on all concepts, acid base theoretical concept was 56%, acid base indicator was 53%, acid base strength was 53%, the ionization constant of acids bases (ka/kb) were 70%, pH solution calculation was 50% and pH concept in environment was 54%. The average percentage of student understanding concept was in class XI grade of science students of senior high school PGRI Pekanbaru on acid-base material was 11% students understand the concept, 55% of student experience misconceptions with moderate criteria, 33% of student do not understand the concept, and 1% of student have an Error.
