3.4.4 Validating Design
After creating the product, the next stage is design validation by the experts. This stage aimed at measuring the appropriateness of the worksheet whether the
educational product is effective or not compared to the worksheet used by the teacher before. By involving the experts in the process, the product would be much more
reliable. Moreover, the validations and suggestions by the experts would cover the weaknesses of the product, so when it is implemented, the error or mistake can be
prevented. To validate the product, this study involved the experts below:
a. Novia Trisanti, S.Pd. M.Pd., the advisor of this study. b. Nur Aini, A.Md., an English teacher in SMP IT Insan Cendekia.
c. Alief Noor Farida, S.Pd. M.Pd., as the expert of language English. d. Maria Johana Ari W., S.S., M.Si as the expert of reading.
Those experts were chosen to validate the product. The teacher was also involved to evaluate the product because the teacher was the one who knew her class better than
anyone, including students’ characteristics and skill. The validation did not only focus on the appropriateness and content of the product, but also the attractiveness of
the worksheet in teaching reading.
3.4.5 Revising Design
After the product was designed and then validated by the experts, the weaknesses of the design would be able to see. Those weaknesses, then, were minimized by doing
revision to improve the product quality. This was done by the researcher. It could
bring the researcher back to the previous stages several times until it got its perfect form.
3.4.6 Product Trial
Product trial is done when all revisions have been approved by the experts. The trial is aimed at getting any information whether the product works well and effective or
not compared to the previous teaching media used by the teacher. In this study, the media were applied in the eighth grade of SMP IT Insan Cendekia in the academic
year of 20142015 and being observed by the English teacher to check its practicality. This stage was conducted as an event to check the readiness of the product before
being in the stage of mass production.
3.4.7 Revising Product
After conducting product trial, the researcher got some feedbacks from the observer. These feedbacks then were used to do correction of the products.
3.4.8 Trial Use
This stage was the same as the product trial stage. The difference was there were some points revised compared to the previous one.
3.4.9 Revising Product
This stage is optional. Since the product was already considered appropriate to be used, the researcher ignored this process.
3.4.10 Mass Production
Mass production is done when the product is declared as an effective product. In this study the researcher just did the mass production for the eighth grade of SMP IT
Insan Cendekia in the academic year 20142015.
