Science Teaching and rating scale (STERS)

From:
Chalufour, Ingrid; Worth, Karen; & Clark-Chiarelli, Nancy. (2003). Science teaching and environment rating scale. Unpublished manuscript.Science Teaching Environment Rating Scale (STERS) (Chalufour, Worth, & Clark-Chiarelli, 2003)
  • The STERS uses a four-point scale (1 = inadequate, 2 = partial, 3 = adequate, and 4 = exemplary)
  • Evaluated whether teacher participants at the three geographical field sites:
    • Created creative learning Environment
    • Facilitates direct experiences to promote conceptual learning
    • Promotes the use of scientific inquiry
    • Plans in-depth investigations.
    • Reliability and validity of the STERS is being studied at this time by the developers at the Education Development Center.
    • All of the classrooms in the pilot study (N = 19) and a sample of the classrooms in the field test (18 out of 23) were observed by the external evaluator.

Findings

Results indicate that teachers were able to implement R&P successfully (see Table 1).
