Abstract
ABSTRACT Learning new concepts in biology is closely related to previously learned concepts. For researchers, teachers and for educational authorities, differentiated knowledge of central conceptions in a field can help to develop, teach and evaluate new learning opportunities or educational approaches. Pre-conceptions have been investigated for numerous biological concepts in recent decades. One comparatively little studied area is that of skeletal movement. This article presents the development and validation of a test on the correlation between structure and function in the movement of extremities. The test was developed for pupils between the ages of 10 and 14, since skeletal movement is primarily a topic in schools at this age. The test comprises 10 items distributed over 2 scales. Validity is confirmed by confirmatory factor analysis, by high correlation coefficients with Science/Biology marks, and by further sources of validity evidence. Investigations of correlations between the test score achieved and personal parameters (gender and grade level) do not show statistically significant correlations, which indicates the fairness of the instrument. With a test completion time of 10 minutes, the knowledge test is time-efficient. The test extends the range of available assessment instruments on biological concepts in the area of the locomotor system.
