THE MEASUREMENT OF ABILITY TO APPLY PRINCIPLES OF PHYSICS IN PRACTICAL SITUATIONS.

The article focuses on a study that validates the assumption that the possession of a wide range of information in physics and the ability to work type problems is an indication of an equally well developed ability in the application of principles. The development of the ability to apply understandings of the principles of physics in practical out-of-school situations is one of the major objectives of instruction in high school physics. The extent to which this objective is, or can be realized as a result of classroom experience is conditioned by the availability of reliable means for determining progress toward the attainment of the objective. The subsidiary problems are also studied as to how each of the abilities which are designated in the major problem related to intelligence and how each of these abilities are related to final grades in courses in high school physics. Duplicate pairs of tests, which were administered to duplicate groups of pupils, have been employed throughout the study. The correlation coefficients reported are within, schools correlations, the effect of school differences in central tendency having been removed through utilization of the method of analysis of covariance.
