b. The Result of Expert Judgment of Unit 2

The tables below present the descriptive statistic of the materials judgment related to the appropriateness of Unit 2. Table 31: The Content Appropriateness of the Unit 2 No Items Scores 1 The topic of the unit of the developed materials is relevant with the students of International Mathematics Education study program. 3 2 The developed materials are in accordance with the learning context of the students of International Mathematics Education study program. 3 3 The developed materials lead the students to perform and develop their reading skills. 4 4 The developed materials lead the students to perform and develop their vocabulary skills. 4 5 The developed materials lead the students to understand the linguistic features of the discussed text. 4 Mean ᵡ 3.6 The table 31 shows that the contents of the materials of unit 2 was considered “very good” by having value in the range of 3.25 ≤ x ≤ 4. It could be seen through the mean of the general judgment which is gained from five questions related to the content of the materials. Table 32: The Language Appropriateness of the Unit 2 No Items Scores 1 The language used in the explanations and instructions are clear and understandable. 3 2 The language used in the developed materials is grammatically correct. 3 3 The language used in the developed materials is cohesive and 3 coherent. 4 The developed materials consistently use one variation of English. 3 Mean ᵡ 3 Table 32 presents the language appropriateness of unit 2. The result of the table 4.26 was considered as “good” by having value in the range of 2.5 ≤ x ≤ 3.24. Table 33: The Presentation Appropriateness of the Unit 2 No Items Scores 1 The tasks are arranged systematically from the easiest to the most difficult. 4 2 The developed materials are balance in terms of texts, illustrations and symbols. 4 3 The developed materials support the students to get information within the texts. 4 4 The developed materials contain opening activities, main activities and closing activities. 4 5 The developed materials are completed with vocabulary list related to the unit topic. 4 6 The developed materials provide evaluation part for the students to check their understanding. 4 7 The learning objectives are stated in every unit of the developed materials. 4 Mean ᵡ 4 Table 33 presents the result of experts’ judgment related to the presentation appropriateness of the materials of Unit 2. The mean of the general judgment of the presentation appropriateness was 4. It means that the presentation of the unit was categorized as “very good”. Table 34: The Layout Appropriateness of the Unit 2 No Items Scores 1 The developed materials are printed on ISO-standardized size paper A4, A5, B5. 4 2 The layout of the developed materials use the appropriate placement of the unit title, sub-title, page number, illustrations and captions. 3 3 The developed materials use the appropriate variation of fonts. 4 4 The fonts used are not too big or too small. 3 5 The color usage of the developed materials is not disturbing the readers. 2 6 The illustration and graphic design in the developed materials are aesthetic and functional. 3 Mean ᵡ 3.1 Table 34 shows the result of analysis of the layout appropriateness in Unit 2. The mean of the layout appropriateness was 3.1. Therefore, the layout appropriateness in Unit 1 was categorized as “good”.

c. The Result of Expert Judgment of Unit 3

The tables below shows the result of the analysis related to the content appropriateness of Unit 3. Table 35: The Content Appropriateness of the Unit 3 No Items Scores 1 The topic of the unit of the developed materials is relevant with the students of International Mathematics Education study program. 3 2 The developed materials are in accordance with the learning context of the students of International Mathematics Education study program. 3 3 The developed materials lead the students to perform and 4 develop their reading skills. 4 The developed materials lead the students to perform and develop their vocabulary skills. 4 5 The developed materials lead the students to understand the linguistic features of the discussed text. 4 Mean ᵡ 3.6 The table 35 shows that the contents of the materials of Unit 3 were considered “very good” by having value in the range of 3.25 ≤ x ≤ 4. It could be seen through the mean of the general judgment which is gained from five questions related to the content of the materials. Table 36: The Language Appropriateness of the Unit 3 No Items Scores 1 The language used in the explanations and instructions are clear and understandable. 3 2 The language used in the developed materials is grammatically correct. 3 3 The language used in the developed materials is cohesive and coherent. 3 4 The developed materials consistently use one variation of English. 3 Mean ᵡ 3 Table 36 presents the language appropriateness of unit 3.
