No matter how you study educational psychology, its ultimate purpose should be its practical application. However, since practical application is consistent with theoretical research, we should not abandon theoretical research by overly pursuing the practicality of theoretical research. As researchers, we are based on theoretical research, and both theoretical research and practical application should be well combined. Currently, domestic scholars consider educational psychology to be a perfect combination of "applied and theoretical research." Today, educational psychology has already made some rudimentary results, but the results are still limited. Lack of application of theory and lack of practice of theory, and even if theory is not the basis for practical application, it is difficult to obtain ideal results. Therefore, in order for educational psychology to gain a great breakthrough in research, one cannot be overemphasized theoretically or practically.
