Validation of the S-STEM Survey Questionnaire using Factor Analysis

Joy B. Araza

Abstract: The main purpose of this study was to establish the construct validity and reliability of the High School Students Attitude towards Science, Technology, Engineering and Mathematics (S-STEM) survey questionnaire. The S-STEM has been developed and validated by Friday Institute for Educational Innovation. The S-STEM Survey contains three constructs measuring attitudes toward STEM content and one measuring attitudes toward 21st century skills. Data utilized in the study were 360 grade school (grades 7 to 12) students from the Eastern Visayas Regional Science High School (EVRSHS). The construct validity of the questionnaire was tested using the Exploratory Factor Analysis (EFA), Principal components analysis (PCA), and Parallel Analysis; while the reliability was tested using Cronbach alpha. Results revealed that the S-STEM questionnaire consisted of nine factors based on EFA and PCA and five factors based on the parallel analysis. The questionnaire has good reliability. It can be concluded that the S–STEM is valid and reliable.
