Assessment of Higher Order Thinking Skills in Genetic Learning: A Validity, Practicality, and Reliability

Abstract

Abstract The ability of higher order thinking skills students in West Sumatra is still low relatively with an average value in the range of 17.88-38.45. This is evidenced by the existence of trial tests at schools in several areas in West Sumatra. One way to improve the level of thinking ability of students is to develop assessment of higher order thinking skills. This research aims to develop instruments of higher order thinking skills about genetic material that is valid, practical and reliable. This study uses a 4-D models development. The subjects of this study were two biology lecturers from Faculty of Mathematics and Science, Universitas Negeri Padang, two biology teachers and 30 students of class XII SMAN 1 Nan Sabaris. Data were collected by using questionnaire for validity and practicality furthermore for getting value of reliability by using test. Based on data analysis, the value of validity, practicality, and reliability obtained an average of 87.72%, 88.54% and 0,80 respectively. In a nut shell, the instruments which is designed has been valid, practical and reliable, which can be used by teachers to measure and foster students’ of higher-order thinking skills.
