(The Effects of Instruction with Underlined Materials and Mastery Learning Methods on the Level of Learning, Recalling and Academic Self-Concept Department of Curriculum and Instruction in Elementary Education-Phd-Ankara, February-1996) This experimental piece of research, which was carried out on four groups, aimed at examining the effects of instruction with underlined materials and mastery learning methods used simultaneously and separately. A control group was taught with conventional methods and the first experimental group was taught with underlined materials. The second experimental group was taught with the mastery learning method and the third experimental group was taught with mastery learning and underlined materials simultaneously. The Pre-test and Final-test model with control group was used as the design of experiment and co-variance analysis and the Duncan Test were used in data analyses. The findings demonstrated that in regard to the level of learning and recalling, there were significant differences among the groups firstly in favour of experimental groups, and among experimental groups, in favour of the second and third experimental groups.
