Area of Science:

  • Educational Psychology
  • Psychometrics
  • Adolescent Development

Background:

  • Assessing student expectations is crucial for educational development.
  • Existing scales may not adequately capture multifaceted student expectations.
  • Validating measurement tools ensures reliable data in educational research.

Purpose of the Study:

  • To establish the dimensionality and construct validity of the School Development Expectation Scale.
  • To evaluate the scale's suitability for Year 12 students.
  • To refine the scale based on empirical data.

Main Methods:

  • Confirmatory Factor Analysis (CFA) was used to test the proposed five-factor model.
  • Rasch rating scale modeling was applied for scale calibration.

Related Experiment Videos

  • A large sample of 8,310 Year 12 students from 70 schools participated.

    • Main Results:

    • CFA confirmed the theoretical five-factor structure of the scale.
    • The scale demonstrated good psychometric properties for the target population.
    • Rasch analysis provided insights for scale refinement.

    Conclusions:

    • The School Development Expectation Scale is a valid and reliable instrument for assessing Year 12 student expectations.
    • The scale's five subscales (vocational, academic, personal, social, religious) are psychometrically sound.
    • Further refinements are recommended to enhance the scale's utility.
