  3. 3. Introduction§ Mental image is . . .like a picture in own brain.§ Mental rotation is . . .Basically about how the brain moves objects in the physical space in amanner that helps with positional understanding of objects in space.§ Technical illustration is . . .The use of illustration to visually communicate information of a technicalnature.3

  5. 5. Method – Making Figures (POSER)Heightsa.  Chest heightb.  Waist heightActivitiesa.  Holding a Ballb.  Throwing a BallCamera Positions1.  Front – 0degree2.  1/3rd Side – 30 degrees3.  Side – 90 degrees4.  1/3rd Back – 120 degrees5.  Back – 180 degrees5B : Top of viewA : Basic View
  6. 6. Method – Data collectingü 41 students who are non-native English speaker participated in this study.ü Having 20 test sheets.6
  7. 7. Method – Data analysis (SPSS)§ Given a score of either 1 or 0.§ The data was entered in SPSS statistical softwarefor data analysis§ A score in the range of 1-5 was reported for eachtest sheet.7
  8. 8. Finding – Cochran Test•  Correct Answer : 1•  Incorrect Answer : 0•  Q = 17.968 Asymp.sig. = .525•  P > .058

  13. 13. DiscussionØ Body height/rotation/action§  When compared with a plan view, it becomesmore various visual cues.•  Accuracy score around the 85 – 95% levelØ Similarity body height – action - rotation§  20 body position – insignificant difference§  Height/Action combinations – insignificantdifference13
  14. 14. Conclusion and Future research§ Explored the effect of Body rotation, height andactionü Increased the accuracy levelsü  reader’s interesting approach§ In the future research…o The level of correctness should be analyzed carrying outtime observation.14
