Shubber, K. E.; Al-Mudaifa, H. S. – Research in Science and Technological Education, 1991
Six types of remedial projection slide programs were tested on male students (n=120) who showed difficulty in visualizing rotation from molecular diagrams. There were no significant differences in improvement of understanding which were dependent on the number of remedial diagrams. However, when slides contained multicolored diagrams, which were…

Seddon, G. M.; Shubber, K. E. – Research in Science and Technological Education, 1984
Investigated use of overhead transparencies containing a sequence of diagrams to represent a three-dimensional structure at different stages during a rotation. Significant learning occurred among 120 Bahraini boys (aged 15-16) when the transparencies contained multi-colored diagrams which were exposed simultaneously or individually in a cumulative…

Shubbar, K. E. – Research in Science and Technological Education, 1990
The purpose of this investigation was to evaluate the effectiveness of six instructional programs with the aim of alleviating the problems encountered by students in visualizing rotation in molecular diagrams. Models were filmed rotating around the three different axes with different speeds with and without shadows. (KR)

Seddon, G. M.; Shubber, K. E. – Research in Science and Technological Education, 1985
Evaluated effectiveness of six instructional programs (each dealing with a different aspect of a spatial task related to diagrams of three-dimensional structures) with Bahraini students (ages 13- to 17-years-old). All brought about a significant degree of learning over all age groups. Implications of these and other findings are discussed.…
