Task 9 Task 10 The First Draft of the Interactive Multimedia

mistakes in writing the instruction on some tasks were the next point that should be revised. The language expert recommended changing “that included” into “that are included” in the instructions of Task 1 in all units. The words “the desired” in the instruction of Task 7 in all units should also be changed into “the correct”. The words “of the words” which is contained in the instruction of Task 8 in all units should be omitted. The subject expert, who evaluated the Physics content, suggested that some changes considering the meaning of some words should be made. The meaning of “generalization”, “propagate”, “propagation”, “excite”, “gap”, ”recoil”, and “sphere” were inappropriate and therefore they were revised. The meaning were revised from “menyebar”, “penyebaran”, “meningkat ke energi yang lebih tinggi”, “celah”, “melompat”, and “bulatan” into “penyamarataan”, “merambat”, “perambatan”, “penyamarataan”, “pindah keluar elektron”, ”jarak”, ”melonjak”, and “bola”. The review that came as results of the questionnaire was then used to revise the materials and decide whether the multimedia was already appropriate or not. When the data of the mean values x ̅ showed that they were ‘Fair’, ‘Good’, or ‘Very Good’, the units of the multimedia were considered as appropriate. 1 Evaluation and Validation of Unit 1 The language expert judgment of Unit 1 resulted in some changes that should be made. In the instruction in overview “that included” should be replaced by “that are included”. An example of how to do the task also should be added. The pictures in Task 3 and Task 4 that work as representations of the target words should be changed into animated pictures. The words “the desired” in Task 7 instruction also should be changed into “the correct”. On the instruction of Task 8 the words “of the words” should be omitted. Table 4.8 below shows the result of the evaluation of Unit 1 from the content expert. Table 4.8.
