The perception scale for curriculum leadership: Validity and reliability study

The purpose of this study was to create a measurement instrument that would be both valid and reliable for assessing middle school branch teachers' perceptions of curriculum leadership. A straightforward random sample technique was used to choose the participants. 343 middle school branch teachers made up the study's sample. The researchers created the "Curriculum Leadership Perception Scale," with 21 items to collect quantitative data. The scale's reliability was investigated utilizing McDonald’s omega coefficient, item discrimination, and split-half reliability analyses, while its validity was evaluated through face, content, and construct validity. For face and content validity, expert opinion and a pilot study were carried out; EFA and CFA were used for construct validity. While the 213 participants' data were used for EFA, the 130 participants' data were used for CFA. Eighteen items were eliminated following the EFA, and a CFA was carried out. The following fit indices were obtained for the scale by the analysis: RMSEA = .062, GFI = .982, NNFI/TLI = .929, CFI = .940, and IFI = .941. The reliability coefficient for McDonald’s omega was .932. Based on the analyses, a valid and reliable scale with 21 items and four components was created to determine middle school branch teachers' perception of curriculum leadership.
