The productivity index.Index productivity (Effectiveness Index) refers to a number that represents progress.In the course of learning by comparing scores from a test score, before learning to score.After the test, and the full score or score the highest with a score of the test.Prior learning When you evaluate the materials that have been produced. We often look to the effectiveness of teachingEvaluation and coordination. As usual, it is the difference of the evaluation points.In 2 styles, is the difference of the test score before and after school test scores.Or a test about the achievement during the experimental group and the control group.In practice, most of the focus on the real differences in outcomes, rather than the result of a statistical difference.But in some cases only two features, comparisons may be insufficient, such as in the case of a trial.Using media in teaching one of the first tests, study group 1 is rated 18%.After school test score 67%, and 2 the test before school grades from.In both cases there is a test (test score prior to the study), which will affect test scores.After learning that increases the maximum, but if (Goodman and Schneider. 1980:30-34) points.(Test score prior to the study), which will affect the test score after learning that is.The maximum increase in each case (face-holed. Lb lb lb: 1-2; reference comes from 1949: Hovland.Unpaged). efficiency (Effectiveness Index), which indexes the contents of.Testing before the trial after trial and testing with the highest score that can be added.Has proposed that the Association of Hovland experiment will be performed properly, certainly.Regardless of differences in test scores (scores first and can score.Place a maximum The effectiveness index is the pointer to the scope and performance of the media interested in Webb.The average percent of points on which the experimental group and per cent per cent of the control group, see.The result represents the percent increase (or decrease) compared with the control group's index score.There are patterns to find efficiencies. Is as follows:
