The Application Of Test Effect In The Study Of The Addition Of Different Denominator Fractions

Test effect refers to the ability to maintain a better level of memory when learning a particular content than an additional study.Most of the experimental materials for the study of the effects are declarative knowledge and lack of relevant research in the field of procedural knowledge learning.In this study,we use the test sample of different denominator addition as the experimental material,and use the classical research paradigm of test effect to explore whether the test effect can be applied in the field of procedural knowledge learning.The experiment adopted 2*2 between subjects design to study conditions(extraction practice and repetition)and final test before the time interval(5 minutes,1 days)as independent variables,to test the effect of 191 pupils in the fifth grade of different fraction addition operation examples learning experiments.The results show that(1)the sample was extracted from practice after learning(test)were correctly in final test sample group was significantly higher than that of repetition,the test effect can be applied to the study of procedural knowledge;(2)the immediate test and delayed test were not significant;(3)learning conditions the final test and the time interval before the interaction was not significant.Experiment two used single factor experimental design between subjects,to extract the practice feedback given as independent variables,102 in the fifth grade primary school students as the subjects,with different fraction addition sample as experimental materials,the feedback is able to experimentally test the effect of promotion.The results show that after the test subjects to provide feedback on the correct rate in final test was significantly higher than that of no feedback group,which is on the testing effect of learning materials to procedural knowledge,feedback can also play a role.
