Comments:

SPSI was developed to measure overall ability of students to understand and use the range of skills related to the cycle of science inquiry. These skills include forming scientific questions, designing scientific procedures, collecting and recording data, analyzing results, using models to describe results and creating scientific presentations. The tool was used by Oregon 4-H in conjunction with several other pre and post tests, including SOS and open ended questions about campers experiences, to assess the quality of their science summer camp.

This study reports the development and testing of SPSI and its usefulness for measuring science inquiry in youth development science programs. Using factor analysis (PCA) to assess the structure of SPSI scales. PCA was used to determine if the set of items were measuring a single construct made up of science process skills. Items loading one factor above 0.40 were considered efficient factor. The scree-plot confirmed one factor solution. For the alpha coefficient for pre and post test the range was 0.81 to 0.95 suggesting good internal consistency and thus reliability.
