Throughout the 1978-1979 school year, four teachers in District 20 in New York City were utilized for the purpose of developing math skills in selected students in four elementary schools. The target students were removed from class for the additional instruction that their needs required. Each teacher met with five groups of students per school day. The periods ran from forty to forty-five minutes for a total of 200 to 225 minutes of math instruction per week for each group. Teacher-student ratio was approximately 1 to 12. Growth in the mean scores for pre and post tests was noted for all the schools. The Math Success Program as it is conducted in District 20 continues to be an impressive success. (Author/RLV)
