Self-Image, Self-Regulation, Strategies, and Motivation were four dimensions of the mathematical metacognition. LMA = learning mathematics anxiety, MEA = mathematical evaluation anxiety.

*p < .05.

**p < .01.

***p < .001.

^a. The mathematics achievement score was the mean score of the two final mathematics achievement tests with the visual-spatial abilities question scores excluded.
