Evaluation of the Cognitive Goals of Oznaki: Enhancement of Spatial Projective Abilities

By Harvey A. Cohen and David G. Green


The OZNAKI Project applies cognitive goa1s to the design of TINY robotics languages and sequences of lessons in which students program simple robots and TV "block" graphics. One such lesson sequence, the "Projection Module" has been designed to emphasize "projection" a fundamental spatial ability. The course was evaluated in a study involving students aged 8 to 13 years. Experimental and control groups consisted of students matched by age: class, and spatial ability (measured by pre-test), with no previous OZNAKI experience. While the experimental group participated in OZNAKI lessons the control group had only their usual maths lessons. The pre- and post-tests took the form of individual Piagetian interviews with the primary school students, and multichoice questionnaires with the Junior high school students, thus giving two distinct studies. Significant enhancement of spatial abilities was found for the experimental group in both the primary and the secondary studies
