ANALYSIS OF FEASIBILITY OF INTEGRATED ASSESSMENT INSTRUMENTS TO MEASURE CRITICAL THINKING SKILLS AND SCIENTIFIC ATTITUDES OF HIGH SCHOOL STUDENTS ON ACID-BASE TITRATION MATERIALS

This research aims to develop and determine the feasibility of an integrated assessment instrument to measure the critical thinking skill and scientific attitude of senior high school students on acid-base titration material. This research used development model 4-D with define, design, develop and disseminate stage. The product was assessed the legibility by 151 students and was assessed the feasibility by 7 chemistry teachers in Sleman Regency, Yogyakarta. The polytomous data generated by the instrument trial was analysed using the WINSTEPS 3.73 program and the Partial Credit Model 1-Parameter Logistic (PCM 1-PL) approach. The technique of analysing data consists of interviews, questionnaires and tests. Data collection analysis used the guidance of interview, questionnaire instrument user response, questionnaire of agility instrument, integrated assessment instrument in the form of description questions. The research result showed that the level of students’ legibility has a reliability value 0.80, and the user instrument response has a reliability value 0.94. The teachers’ response to the integrated assessment instrument was stated very good. Therefore, an integrated assessment instrument is feasible to be used to measure the critical thinking skill and science attitude of senior high school in on acid-base titration material.
