The aim of this study is to analyse the effect of task planning with mind maps on the self-regulation strategies and motivational beliefs of pre-service teachers. A quasi-experimental design, with a pre-test and post-test control group, was applied in the research. The research group comprised of 60 pre-service teachers taking "Teaching Principle and Methods", in the second year at the Faculty of Education Elementary School Department at Mersin University, Turkey. Students in the experimental group planned their tasks individually by means of a mind map, whereas students in the control group directly realized their task. Before and after the experiment, both groups completed the "Motivated Strategies for Learning Questionnaire", while students in the experimental group also completed the open-ended questionnaire. The research results indicated that there was a meaningful difference between the self-regulated learning of both groups, in favour of the experimental group. Pre-service teachers comprising the experimental group stated that planning by means of mind map had positive effects on the use of self-regulation strategies and their motivation.
