The Effect Of Worked-Out Examples With Practice On Comprehending Geometry Proof

This study examines how reading comprehension of geometry proof is influenced by worked-out examples. Participants are 85 Taiwanese students from grade eight who are novices at deductive proof in geometry. The result shows that average and higher level students can obtain half or more scores in reading comprehension posttest, but the average and lower level students retrogress significantly in delayed test. The main reasons for students' failures in writing proof are: (1) Students disregard the whole logical structure of proof only by repeating the steps from worked-out examples; (2) Students fail to apply proper related knowledge in proving.
