6. The Review of the First Draft by the Experts
The expert judgment is aimed to get the experts’ suggestions about the first draft of the materials. The multimedia is reviewed by two content experts and
a media expert. Since the multimedia is developed for the students of Physics Education Department, the content experts consist of language expert and subject
expert. The feedbacks from the experts are used to design the final draft of the media and to assess whether the multimedia is appropriate or not. The
questionnaires for the experts can be seen in Appendix A.
a. The Review from Content Experts
The language expert, who evaluated the English materials, suggested that some changes in the multimedia should be made. The first was to add an example
in each task in all units. The example is needed to make the user easier to understand the instruction.
The pictures in Task 3 and Task 4 in all units needed to be changed into animated pictures. Twenty nine animated pictures were made to replace them. The
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.
