The experimental research utilized a one-group design, using a test of mathematical problem-solving strategies and a mathematical self-esteem Scale as instrumentation. The results of the study revealed an improvement among the students taught by the strategies of mathematical problem-solving and mathematical self-esteem. In addition, the program revealed the effectiveness and effect of the strategies of solving mathematical problems, while the strategies of mathematical self-esteem showed only an effect, but not effectiveness. The results also showed a moderate positive relationship between students’ possession of problem-solving strategies and mathematical self-esteem. The results obtained were discussed in detail in the section of findings and discussion.
