A programming ability has been required in many areas because of the progress of information technology. As a result, a programming education is becoming more important than ever before. However, there is an issue that programming exercises do not work effectively when they are introduced to entry level students. The introduction of programing education should be more attractive so that students can become interested in programming and engage in it independently. In this report, we suggest a method of small-step exercises in order to provide a learning environment in such a way that students work on exercises independently as well as actively. The questionnaire survey shows the method we implemented is very effective.
