- W2995272380 abstract "This study aims to determine the learning difficulties of learners using the Attribute Hierarchy Method (AHM) with ordered multiple choices (OMC) model on chemical equilibrium. The Instruments develop used ADDIE (Analyze, Design, Development, Implementation and Evaluation) model. The research instrument used a multiple-choice test that has a score that all correct answer options. There are 8 types of attributes concerning chemical equilibrium in the instrument. The sample was high school students in Pekanbaru. Instrument validity includes material, construction, and language aspects. Based on the validity test results obtained that the developed instrument has been in valid category. Material validity aspect value 3.50, validity of the construction obtained value 3.7 and aspects of language value of 3.59. Instrument reliability test results using the formula of KR-20 obtained a value of 0.717 in high category. The learning difficulties of learners obtained that learners have the greatest learning attribute 6, which is the equilibrium constant of pressure (Kp) which has not been mastered by 58% of students 2.) Attribute 7 is the relationship between Kp and Kc that has not been mastered by 63.75% students, 3.) Attribute 4 is Le Chatelier's principle which has not been mastered by 80% of students and 4.) Attribute 8 is the degree of dissociation that has not been mastered by 77.5% of students." @default.
