Ways in which games can be used as tools in observing, diagnosing, and providing educational therapy for learning dysfunctions are listed and described in a series of four related papers: (a) "Educational Therapy for Learning Dysfunctions"; (2) "Educational Therapy and Puzzles"; (3) "Educational Therapy and Reading Fluency"; and (4) "Spelling Errors--Where?" The value of the game approach is noted and examples of the approach using crossword puzzles, which can be used for diagnosis as well as training, are offered. Other types of puzzles are advocated as ways to deal with distraction, unorganized thinking, and lack of motivation. Steps in puzzle solving are noted. A case study is presented of a 7-year old, diagnosed as hyperactive, who learned to sustain attention with a puzzle task. It is noted that many children seem hyperactive because of bad working habits, failure, and low self-confidence. The role of educational therapy in improving reading fluency and spelling accuracy is further examined. (CL)
