Having identity to facilitate the administration such as class, lesson, and topic

95 these LKS, each one of them fulfills this criterion well. Based on the finding, the researcher gives each chapter 1 point due to the perfect achievement. The comparison between the topics‟ letter size and the ordinary explanation letter size is as seen in the following picture. Each topic in every chapter is given a special treatment. Special treatment here means that each of them is given a frame. The following picture is taken from LKS Formatif 2. It is the picture of the first chapter of the second LKS. This LKS Formatif 2 is used by XI grade of vocational high school students. Figure 4.51 The front size of the topic Another point is that these three English LKS show a great consistency in way of writing down the topic in the same font type and also same letter size. Each topic is written with bigger size and in the bold mode.

2. Using short sentence

According to the research finding, all three LKS Formatif failed in fulfilling this point. The result finding shows that all of these three English LKS have not fulfilled this criterion. The researcher found that these three LKS had a tendency to 96 provide a very long sentence both in the explanation part and also in the instructional sentences. According to the criterion, one sentence should not consist of more than 10 words. 10 words in one sentence would become the maximum amount of the words that formed a sentence. The researcher could not find any chapter on each LKS Formatif which fulfilled this criterion. Based on the rule, the researcher gave each chapter on each LKS 0 point. The following picture is a figure of an instructional sentence which consisted of more than 10 words in one sentence. An instructional sentence is supposed to be simple and easy to understand. The instructional sentence in the picture consisted of two instructions in one sentence. The picture is taken from page 5 of the LKS Formatif 1. Figure 4.52 A very long instructional sentence The instructional sentence above was an example of a quite long sentence. Another problem was that sentence also contained a grammatical error. The sentence sounds like this “in pairs, complete the dialogue with your own and practice them with your partner in front of the classroom”. The words your own should be corrected into on your own.
