2. Data Analysis Technique of the Post-design Research

The results of the evaluation questionnaire distributed toward the evaluators were then analyzed to make a final conclusion. The evaluation questionnaire was valued by choosing the scale provided in the questionnaire. The scale used was the modification of Likert’s scale. The researcher decided to arrange the scale from 1 to 4 degree of agreement. Each degree of agreement was clarified below. 1 : strongly disagree very poor 2: disagree poor 3: agree good 4: strongly agree very good The technique used to calculate the final score for each assessed item was proposed by Brown and Roger which was known as “mean” or “average.” It was discovered by calculating the total scores of the evaluators’ answer for each assessed item w x and dividing it with the total number of the evaluators N. The formula was showed below. Note: M = mean of the final score w x = the total score of the evaluators’ answer N = the total number of the evaluators w x M = N 48 The accumulation scores of all items evaluated in the evaluation questionnaire indicated whether the materials were good and acceptable or not. The term good and acceptable were given to the designed materials with at least three degree of agreement for each assessed item. On the other hand, if the average point of the degrees of agreement for each assessed item was less than three, it meant that the materials needed a lot of revisions.
