This study is aimed at determining the effectiveness of the use of a science textbook integrated with the local potentials of bakpia in improving the critical thinking and communication skills of the junior high school students. The study was a quasi-experiment with a pretest-posttest control group research design. The experiment and control groups were taken by cluster random sampling by considering the location of the school, which is within proximity of the local potentials in question. The study was conducted in the 7 th grade, at one of the junior high schools in Yogyakarta, both for the experiment and control classes. The research instruments were an open-reasoned multiple-choice test and observation sheets to obtain data on students’ critical thinking skills and communication skills. Data analysis was done by the Manova difference test assisted by the SPSS 2.0 computer program with a significance value lower than 0.05. Results showed that the value of the partial Eta squared from the Manova test was 0.981, indicating that the effectiveness of the science textbook integrated with the bakpia local potentials to improve students’ critical thinking and communication skills was in the “high” category. The test of between subject effects of the Manova test showed a significant value of students’ critical thinking and communication skills of less than 0.05. Therefore, it can be said that the science textbook was effective in increasing students’ critical thinking and communication skills, simultaneously. A limitation to the study can be in the fact that the study is not conducted directly in the bakpia factory and that it involves only 60 subjects for both the experiment and control groups. The integrated textbook of bakpia local potentials can be used as a reference for future researchers with other local potentials. The local potential integrated book can also become an alternative-learning mode, e.g.: based on STEM, with materials suitable for local potentials in other regions.

In this study, we aim to assess the effectiveness of Project-Based Learning (PjBL) based on Multiple Intelligences (MI) theory on students' critical thinking and mathematical communication skills. This research is a quasi-experiment using non-equivalent (pre-test and post-test) control-group design. The population in this study were VIII grade students in a public junior high school in Yogyakarta and two sample classes were selected based on recommendations from teachers and had mathematical abilities that could be considered equal. The experimental class applied PjBL based on MI theory and the control class applied PjBL learning. Data collection was conducted using a test instrument in the form of description questions. This instrument is valid and reliable. Learning is said to be effective if: (1) the mean test score of critical thinking and communication skills is at least 70 (from a score range of 0-100); (2) the mean of post-test of critical thinking and communication skills is higher than the mean of pre-test; (3) the mean final score of students' critical thinking and mathematical communication skills in the experimental class is higher than the control class. Data analysis used one-sample t-test, paired-sample t-test, and T2 Hotteling test. The results of the study using the significance level α = 5% showed that (1) PjBL learning based on MI theory is effective in terms of students' critical thinking and mathematical communication skills; (2) PjBL based on MI theory learning is more effective than PjBL learning in terms of communication, but not more effective in terms of critical thinking skills. Although the data from the sample showed the acquisition of mean scores and the increase in the mean value of critical thinking learning in PjBL based on MI theory was better than PjBL learning in terms of critical thinking skill, but statistically both did not show a significant difference.

Some 21st century skills that must be possessed by students are critical thinking and communication skills.

This study aims to determine the mathematical critical thinking and communication skills of high school students in trigonometry materials. This research uses descriptive qualitative approach. Subjects were randomly selected from 10th grade as many as five students. The instrument used was a test of critical thinking skills, communication, and non-tests in the form of an attitude scale questionnaire of 16 statements. The results showed that students had critical thinking skills and communication in the low category. Students are not able to complete trigonometry questions completely. This is because students are poorly trained in solving trigonometric problems with non-routine questions. Based on the findings, it can be concluded that: (1) mathematical critical thinking skills of five students of class X on trigonometry material are still relatively low. (2) Mathematical communication skills of five students of class X on trigonometry are still relatively low. (3) There is a relationship between critical thinking skills and mathematical communication of students. (4) And students’ attitudes toward mathematics learning, tests of mathematical critical thinking, and communication skills on trigonometric material are good. So the critical thinking skills and mathematical communication of five students in trigonometry material are still lacking because students have difficulty in modeling trigonometry problems, and stuck with modification questions because many students are not able to complete the answers to the questions given.
