TEACHER TRAINING PROGRAM ON TEACHING ARITHMETIC MEAN BY USING THE VISUAL APPROACH- A CASE STUDY

This paper describes an action research carried out over eight days on an elementary mathematics teacher in the United Arab Emirates. The effectiveness of a short teacher training program using the visual approach in teaching the concept of arithmetic mean was examined. The teacher was trained to teach a sixth grade class using a visual approach that focused on teaching the conceptual understanding of the arithmetic mean. Results showed some positive effects of the short training program on students' conceptual understanding of arithmetic mean. Some misconceptions related to arithmetic mean were found among students in pre and post testing.
