The Study Of Comparing The Effect Of Dynamic Worked-example With Static Worked-example During Parabola Feature Judgment Rule Learning

In order to inspect the effect of dynamic worked-examples and static workedexamples in analytic geometry learning,we conducted three experiments which used parabola feature judgment rule as material of worked example learning and invited second-year junior high school students as subjects on comparing effect of dynamic and static example learning.Experiment 1 which randomized between subjects examined the achievement that 60 eighth graders performed after they had learned the rule of parabola orientation judgment.During the experiment,half of the student learned rules by dynamic worked examples and others by static.Experiment 2 examined the achievement that 60 eighth graders performed after they had learned the rule of parabola opening size judgment.During the experiment,half of the student learned rules by dynamic worked examples and others by static.Experiment 3 examined the achievement that 60 eighth graders performed after they had learned the rule of parabola orientation combined opening size judgment.During the experiment,half of the student learned rules by dynamic worked examples and others by static.Results showed that:(1)Junior two students could acquire the rule of parabola(y=ax~2,a?0)orientation judgment as well as opening size judgment on different levels through dynamic worked-examples or static worked-examples.And there is no significant difference between two types of workedexamples.(2)Junior two students could acquire the rule of parabola(y = ax~2,a?0)orientation combined opening size judgment on different levels through dynamic workedexamples or static worked-examples.And the achievement that performed by dynamic worked-example group significantly better than static worked-example group.
