The Validity and Reliability of The Instrument Assessment of Higher Order Thinking Skill on The Biological Scope Materials

Abstract

High Order Thinking Skill (HOTS) requires students to connect, analyze, and also transform 
 their knowledges and experiences. To determine students' high-level thinking skills, we can 
 use assessment instruments. A good instrument should be valid and reliable so it is feasible 
 to measure and assess what it wants to be measured and assessed. Therefore it is necessary 
 to know the level of validity and reliability of the higher order thinking assessment 
 instruments. The instrument used in this study in the scope of biology material. This type of 
 research is descriptive research. The subjects of this study were students of grade X MIPA 5 
 SMA 5 Padang. Based on the results of data analysis, the assessment instrument of high 
 order thinking skill on biological scope material is logically valid, empirical valid and 
 reliable.
