Correlation Amongst Understanding of NOS, Conceptual Understanding, and Science Process Skill of Undergraduate Students on General Chemistry

The aims of this research were to study the correlation between NOS Understanding and Conceptual Understanding and between NOS Understanding and Science Process Skills. This study also serves as an empirical validity test of the NOS understanding questionnaire that researchers have developed. This correlational research was carried out at the Faculty of Mathematics and Science Education of IKIP Mataram. Ex post facto method was employed in this study. The study involved 75 students taking General Chemistry course for the academic year of 2018-2019. The participants were selected by using the saturated sampling method. Data were collected using a NOS understanding questionnaire, concept understanding test, and observation sheet of science process skills. The data are presented descriptively. The correlation test was carried out by using product moment test. The results uncovered a strong and significant correlation between NOS Understanding and Conceptual Understanding and between NOS Understanding and Science Process Skills. The results of this study indicate that the NOS understanding questionnaire has been compiled can be used to measure the level of students' understanding of NOS and predict students' performance of science process skills and conceptual understanding in chemistry learning.
