Student teachers usually face problems in delivering information and ideas and achieving behavioural objectives during the period of their application in intermediate and preparatory schools. This is due to their reliance on traditional teaching methods during their teaching performance and their failure to keep pace with modern educational programmes that would raise their performance efficiency during and beyond their application period. The current study aims at: 1. Constructing an educational programme based on creativity strategies. 2. Finding the impact of the constructed educational programme on the performance efficiency of student teachers. The experimental design with pre- and post-test for one group is adopted. A sample of fifty student teachers in the Department of English / College of Education for Humanities/ University of Tikrit, which represents 15% of its total population of the study is selected. In order to achieve the aims of the study an educational programme based on creativity strategies has been constructed. The student teachers have been trained according to the constructed educational programme for a period of eight weeks. An observation checklist, rather than a written test, was used to assess the participants' teaching performance before and after the educational programme so, an observation checklist has been constructed as an instrument of the current study to assess the student teachers’ performance efficiency. The observation checklist includes thirty- five items distributed among three areas, namely: planning, implementation, and evaluation. The obtained results in the current study show that the application of the educational programme on the experimental group has improved their performance efficiency. Based on the findings, this study ends up with a number of conclusions and recommendations.
