  3. 3D Models • Learners with high spatial ability benefit from the presence of 3D models. • High spatial ability learners perceive their cognitive load to be low when working with 3D models. • Psychomotor skill is directly affected by a learners working memory and ability to keep up with time. • Spatial ability skill affects psychomotor skill • Perceptual Input: visual, auditory, tactile • Motor Output: manual, ocular, vocal, motoric systems Who benefits from learning with 3D models? The case of spatial ability

  4. Dimensions • Dimensions are the parameters required to describe the position of any object within a conceptual space. http://www.reference.com

  5. 3 Dimensions • The three dimensions are commonly called length, width, and depth. • Pictures are commonly two dimensional, they lack depth. • A three-dimensional picture, tricks the human eye into experiencing the illusion of depth. http://www.reference.com

  6. Spatial Visualization • Spatial Visualization Ability refers to the ability to mentally manipulate 2-dimensional and 3-dimensional figures. • It is predictive of user performance with some kinds of user interfaces. http://www.reference.com

  7. Psychomotor Tasks • Requires eithercomplex perceptual discriminations or productions ofcomplex motor response. Activites Click for examples of activities that require psychomotor ability Organization and Components of Psychomotor Ability

  8. Activities Requiring Psychomotor Skills

  9. Cognitive Load • Cognitive Load is a term that refers to the load on working memory during problem solving, thinking and reasoning (including perception, memory, language, etc.) • The aim of instructional design is to increase the cognitive load during the learning process, without cognitive overload. http://www.reference.com

  10. Quick Quiz • The 3 dimensions of an object are: shape width color depth size length

  11. Right on….!

  12. Quick Quiz • People with high spatial visualization skills can easily visually manipulate 2 and 3 dimensional objects. True False

  13. Right on….!

  14. Quick Quiz • Pictures are commonly two dimensional, they lack depth. True False
