The Reliability and Validity of an Instrument to Evaluate the Implementation of Program i-THINK

Abstract

In order to assess the execution of a programme known as 'Program i-THINK' in schools, a reliable and valid instrument is required. The research aimed to develop and validate the instrument. The instrument utilised was a questionnaire distributed to 160 primary school teachers. The context, input, process, and product or CIPP Evaluation Model, established by Daniel Stufflebeam, served as the foundation for the instrument. Experts examined the content validity of the instrument, while Exploratory Factor Analysis was utilised to assess the construct validity. Internal consistency reliability, often known as alpha coefficient reliability or Cronbach Alpha, was used to assess the reliability of the instrument. The pilot study findings suggest that the instrument is reliable and valid. Consequently, 98 items were retained out of 133 items.
