The article presents the study that examines the effect of three different modes of task orientation on observational attainment in practical chemistry. The modes include an open-minded approach, a method of partial direction, and a check-list approach. The study investigated 140 fourth-year 'O'-level chemistry students from three schools. Two tests were applied which include chemistry theory test and color vision test. Two charts were presented related to the tests done. It was concluded that the checklist mode of task orientation seems to be most effective to get high observational achievement, but has the disadvantage of causing a high illusory error rate. Since there had been no study carried out to know how students cope with the interpretation of sets of observations due to omission errors, the open-ended and the checklist procedures cannot be fully evaluated. |
