Developing Scientific Attitudes Instrument of Students in Chemistry

Abstract

This research aims to evaluate the attitude instrument which will be used to asses the scientific attitudes in chemistry classes in High School in Parepare. The research will provide informations to identificate student scientific attitudes. Scientific attitudes in this paper consist of scientific attitude indicators. They are curiosity, honesty, objectifity, perseverence, conscientious, openness, being critical, and being responsible. The instrument evaluation is done by testing it to high school student to get its validity and realibility. The instrument has 8 aspects with 32 statements. The analysis result shows that Kaiser-Mayer-Olkin (KMO) indicator is 0.922. The Measure of Sampling Adequancy (MSA) in anti image correlation indicates that all of variables is greater than 0.5 which allows the data to be analysed further. The amount of variance and variable that can be explained by the factors forms 6 factors and cumulative variance 61,884%. The 32 items in the instrument, 26 items are fulfill the 6 factors. The Realibility of all items using Cronbach Alpha coefficient is 0.948. The analysis denotes that the instrument can be used to measure the student scientific attitudes in chemistry class with 26 items and 6 factors. The results of the analysis show that the instrument can be used to measure students’ scientific attitudes on chemistry learning with the number 26 and 6 factors formed.
