This action research project evaluated a program for improving motor skills in kindergartners by incorporating into the core curriculum motor activities, new materials focused on motor skills, and authentic assessments of motor skills. Teacher observations, scores from the DIAL-R (Developmental Indicators for the Assessment of Learning-Revised) test, teacher checklists, parent surveys, and interviews with an occupational therapist provided evidence of underdeveloped motor skills among the kindergartners, with weaknesses in tasks such as handwriting, cutting, tracing, balancing, catching, and hopping. Post-intervention data indicated an increase in motor skills development among the children, an improvement in their attitudes toward the targeted motor skills, and an increase in the ease with which targeted motor skills were accomplished. (Eleven appendices contain survey and checklist materials, photographs of motor activities, and assessment materials. Contains 23 references.) (EV)
