Exploratory Factor Analysis Research Instrument Confidence Attitude Toward Students

This article examines the analysis of the validity of constructs on an instrument. The instrument used was a questionnaire about the students’ self-confidence. This analysis is done in order to know what factors affect the attitude of confidence to students. Analysis of construct validity is done by exploratory factor analysis with the help of SPSS program version 22. Quantitative descriptive research is used in this research. The number of samples used was 50 respondents. The results of this study indicate that 1) In the exploratory factor analysis performed, the value of KMO of.588 which means the sample used as much as 50 already meet the adequacy. 2) Insufficient MSA value >.50 is 3, 4 and 12 so it needs to be re-analyzed. The value of the MSA has qualified after the analysis without the three items. 3) Considering the value of communality >.50, then points 2 and 11 do not qualify with each value of 0.485 and 0.477 means it needs to be re-analyzed. After re-analyzed, the value of KMO, MSA and communal have been fulfilled. 4) Testing with exploratory factor analysis, there are 4 factors of research instrument self-confidence to the student with total variance that is explained equal to 65.806% from result of measurement. Of the four factors obtained, it can be grouped based on the factor load more than.05. Factor 1 contains points 1, 10, 13 and 17. In Factor 2 contains points 8, 14, 15 and 18. Factor 3 contains items 5, 6 and 9 and factor 4 contains items 7 and 16. Based on factor loads after rotating, naming the four factors each is courage, persistence, optimism and life challenge.     Keywords: Attitude of Confidence, Construct Validity, Exploratory Factor Analysi

Pengembangan Instrumen Asesmen Pengetahuan Fisika Berbasis Komputer Untuk Meningkatkan Kesiapan Peserta Didik Dalam Menghadapi Ujian Nasional Berbasis Komputer

This research aims to 1) produce computer-based assessment instruments eligible to measure the cognitive abilities of senior high school students, 2) test the effectiveness of computer-based assessment instrument developed to measure the knowledge of physics in senior high school students, 3) measuring the level of readiness of students in dealing computer-based national examanation. This research uses a model of Research and Development (R & D) which consists of three main stages: the preliminary stage, the stage of development and evaluation phase. At the preliminary stage has been identified problems of computer-based assessment of learning physics. At the development stage has been carried out the design manufacture of computer-based assessment instrument physics, product validation, product revisions and testing of products on a limited basis. In the evaluation stage has been tested extensively, product revision, and the final product. Descriptive statistical test used to describe the results of the application of computer-based knowledge assessment. The results research show that : 1) computer-based assessment instruments eligible to measure cognitive abilities of senior high school students, 2) computer-based assessment instruments are more effective and efficient to measure the students knowledge of physics in senior high school rather than paper and pencil test, 3) 58.67% of students are ready to face computer-based test, 34% of students not yet ready for the computer based test and 7.33% are not ready to perform the test based computer
