The problem of developing instructional materials for junior high-school general mathematics classes is a difficult one. Because of the diversity of interests and previous training of the pupils who are normally enrolled in these classes it is hard to find topics which are sufficiently interesting and general in their appeal to meet the needs of a majority of the pupils found in these classes.

Guided Discovery

The reality found in school showed that the teaching and learning experiences were dominated by the use of the Direct Instruction model and there were no activities to facilitate students to think criticaly. Thus, it is necessary to develop  guided discovery learning materials to overcome it. The one group pretest-posttest design was used as a the research design involving 30 Junior High School students. The data were analyzed through descriptive qualitative technique. The results showed that students’ activities were consistent with each stage of the guided discovery learning, students’ responses were good, and N-gain test informed that the students’ learning outcome and their  capability  to use  critical  thinking  skills  increased.  Based  on  those  findings,  it  can  be  concluded  that  the  guided  discovery instructional materials were effective to facilitate Junior High School students by think critically.Kenyataan di sekolah metode pembelajaran yang digunakan lebih berorientasi pada Direct Instruction dan belum  tersedia    perangkat  pembelajaran yang  dapat  melatih  keterampilan  berpikir  kritis  siswa  sehingga  perlu dikembangkan pembelajaran yang berorientasi pada penemuan terbimbing untuk melatihkan keterampilan berpikir kritis kepada siswa SMP. Rancangan penelitian one group pretest-posttest design dengan subyek 30 orang siswa SMP. Data dianalisis secara deskriptif kualitatif. Hasil penelitian menunjukkan aktivitas siswa sesuai dengan tahapan penemuan terbimbing, respon siswa baik, uji N Gain menunjukkan peningkatan hasil belajar dan kemampuan berpikir kritis serta pembelajaran penemuan terbimbing, pokok bahasan peran manusia dalam pengelolaan lingkungan efektif untuk melatihkan keterampilan berpikir kritis siswa SMP.

The research aims at developing culture-based English instructional materials (henceforth, CBEIM) for grade VII of Junior High School students and reveal its final product representation in terms of its effectiveness. The research design was a research and development. The procedure of product development consisted of conducting needs analysis, designing course grids, developing the first draft, implementing the final draft, and evaluating the final product. The product implementation consisted of the 1st tryout involving 4 students from Yogyakarta State Junior High School (henceforth, Y-SJHS) 10, the 2nd tryout involving 34 students from Y-SJHS 7, and there were 68 students involved in the 3rd tryout. They were from Y-SJHS 9 and Y-SJHS 10. The data were collected by using evaluation sheets, an English achievement test, questionnaire to measure students’ level of internalization and actualization toward culture values, and questionnaires for teachers’ responses. The data were analyzed by t-test using paired and independent sample with the gain score. The research finding reveals 1) based on the content expert validation, CBEIM was very good by the aspect of content, language, learning, culture, presentation, and graphical design, whereas based on the graphical design expert, CBEIM was good. 2) Having been implemented, the final product representation was proven to be effective. The students in the experiment classes got a higher improvement than those in the control classes. The statistical calculation of independent samples test with gain score of the English test from the two groups shows the t values of 2.931 with the p = 0.004 < 0.05, while the t-test for equality of means of culture values, t value reached 2.524 and its significance of 2-tailed reached p = 0.037 < 0.05, alpha value (α=0.05). Since the gain score is smaller than 0.05, CBEIM demonstrates that it can show a significant difference between the experiment and control classes in encouraging students to internalize and actualize the culture values.

The values of nationalism can be integrated into instructional materials as a way to achieve competence standards set by the government. This study aimed to produce nationalism-oriented interactive materials for news item learning in junior high school. This study employed a research and development design that consisted of seven stages, including data analysis, product design, prototype development, expert validation, product revision, small-group tryout, and final model revision. The result of the analysis showed that the interactive materials could meet the teacher’s and students’ needs in learning news item and the development of the product was in line with the principle of instructional material development. The interactive instructional materials were packaged in a compact disk (CD) containing an application called Macromedia Flash. The values of nationalism integrated in the instructional materials include the pride in the national language which is Indonesian Language, the love for the country, the spirit of preserving national songs, heroism, discipline, and hard work. These values were embedded in the form of visual, audio, or audiovisual media that can be displayed in the classroom and thus used to study listening.
