The Effect Of Contents Of Feedback On High School Students For Studying Series Reasoning

Contents of feedback as an important factor constrain the effectiveness of feedback. On the basis of past researchers'theories and experiments, this study investigates the feedback effect of different amounts of information and different types of learning-guided feedback for the learning of students. This study consists of two experiments.Experiment 1, to investigate the influence about three different types of the correct answers on the amount of information for three different levels of students for learning math series reasoning, we choose series reasoning (arithmetic progression, geometric series and mixed series) for the experimental materials, and choose high school students on the first year as subjects (who are divided into superior, middle, and poor on three levels according to math).The results show that:providing the superior students with "the key formula about problem solving", they perform best; providing the poor students with "all correct answers about problem solving", they perform best; for the middle students on math, the two feedbacks show no significant learning differences, but they are both better than feedback about only learning the correct answer.Experiment 2, to investigate the effect of correcting the mistakes about three different learning-guided feedback for the learning of high school students on the first year, we divide learning-guided feedback into three types, respectively "the cause of the error", "the explanation of correct answer" and "the cause of the error + the explanation of correct answer". We choose high school students who made the mistakes on series reasoning as subjects (who are randomly divided into three groups), providing them with three different types of learning-guided feedback, and testing their scores. The results show that:there are significant differences between the types of feedback on the post-test scores. Specific case as followed, the third feedback performs best, next is the second one, while the first feedback makes the poor performance.
