Learning the Visualisation of Three-Dimensional Spatial Relationships in Diagrams at Different Ages in Bahrain.
Peer reviewed Peer reviewed
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.…

The Factor Structure for Mental Rotations of Three-Dimensional Structures Represented in Diagrams.
Peer reviewed Peer reviewed
Seddon, G. M.; And Others – Research in Science and Technological Education, 1985
Determined the factor structure of tasks which require students to visualize how diagrams should be drawn to represent effects of rotating three-dimensional structures about the three Cartesian axes. Results obtained from 149 English and 231 Singapore students show that visualization about X-, Y-, and Z-axes are factorially distinct. (DH)

The Understanding of Pictorial Depth Cues, and the Ability to Visualise the Rotation of Three-dimensional Structures in Diagrams.
Peer reviewed Peer reviewed
Seddon, G. M.; Eniaiyeju, P. A. – Research in Science and Technological Education, 1986
Explains an investigation which examined Nigerian students' (N=200) ability to respond to depth cues and to visualize the effects of rotations. Study results indicated that performance on cues tests correlated significantly with performance on rotation tests suggesting that cues influence students' ability to visualize the effects of performing…

Comparison of the Standard and Reliability of the Assessments of Practical Scientific Skills Using Groups of Different Sizes.
Peer reviewed Peer reviewed
Hubbard, J. I.; Seddon, G. M. – Research in Science and Technological Education, 1989
Investigates differences in marking standard and reliability when experienced teachers carried out assessments of the performance on practical exercises. The results showed that there was no difference between the assessments from the groups containing 5 and 20 students. (Author/YP)

The Effects of Using Scientific and Household Apparatus on the Results of a Primary School Experiment.
Peer reviewed Peer reviewed
Seddon, G. M.; Ridge, J. S. – Research in Science and Technological Education, 1987
Investigates the effects of using scientific apparatus versus household objects on the accuracy of primary school children in a simple titration exercise. Indicates no significant difference between the accuracy obtained using the two types of apparatus at the beginning, but improved performance for children using scientific apparatus by the end.…

The Effects of Presentation Mode and Colour in Teaching the Visualisation of Rotation in Diagrams of Molecular Structures.
Peer reviewed Peer reviewed
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…

A Comparison of Written and Oral Methods of Testing in Science.
Peer reviewed Peer reviewed
Seddon, G. M.; And Others – Research in Science and Technological Education, 1990
Discussed in this study is whether there are differences in the assessment of student understanding as measured by written tests versus oral tests. Age and sex differences as well as the impact of different languages and cultures were investigated. (KR)
