The Validity and Reliability of Students' Soft Skills Assessment Instrument of the Invention Subject

Abstract

This article discusses the validity and reliability of students’ soft skills assessment instrument of the invention subject. All items are built based on the adaptation of several theories and models of soft skills and literature studies that have been obtained locally or from abroad. The result of this study has submitted eight important constructs in implementing the assessment of secondary school student’s skills through communication skills, technology usage skills, skills in planning and organizing activities, skills of working with other people and in groups, problem-solving skills, management skills, choosing and analyzing information, skills of using mathematical ideas and techniques, and the skills of cultural understanding. Expert validity involves the lecturers of local universities, teacher education institutes, and teachers who have experienced in education for more than 10 years. A total of five experts were involved as a validity assessor for content and five panels as a practice expert to determine the item validity from the aspects of wordings, language register, and sentences in each item built. In addition, the quantitative measurement method through Content Validity Ratio (CVR) has been used to evaluate the items whether it is necessary to keep or to be modified. The findings found that all the items built have fulfilled the measurement features of an instrument and can be used as a tool for measuring the soft skills of students in secondary schools.
