In 21st century learning, critical thinking skills are the main choice that must be mastered by students. This study aims to determine the effectiveness of local wisdom-based science teaching materials in improving junior high school students’ critical thinking skills. Most science teachers still apply teacher-centered learning, so students tend to be passive. This type of research is quasi-experimental with a pretest-posttest control group design. The study was conducted in the even semester of the 2019/2020 school year. The subjects of the research were grade VII students. Data collection techniques and instruments in the form of tests that include indicators of critical thinking skills. Data analysis used homogeneity test, Kolmogorov Smirnov normality test, independent sample t-test, and n-gain score. The results of the independent sample t-test are sig. (2-tailed) = 0,000<sig. α = 0.05. Students’ critical thinking skills in the experimental class were higher (N-gain score = 39.09%) than in the control class (N-gain score = 12.03%). Based on the study results, it can be concluded that there is a significant influence on the application of local wisdom-based teaching materials in improving the critical thinking skills of middle school students in the moderate category.

The Covid-19 pandemic has caused several changes in the human state of mind, in particular adapting to the culture of the new normal while lockdown measures are implemented. This study explored the effect of the lockdown measure on the level of anxiety of high school students, comparing those identified as introverts and extroverts. Participants (N = 103) filled out the given survey, which determined that they were both introverts or extroverts and the level of anxiety that they had before, during, and after the lockdown caused by the pandemic. According to statistical analysis, the result showed that the level of anxiety perceived by those feeling the sense of extroversion was statistically higher than those with introversion, at the significance level of 95%. In addition, the analysis revealed that there was no correlation between extroverts and anxiety before, during, and after the lockdown measures. On the other hand, there were statistical correlations between the level of introversion and the level of anxiety in every stage of lockdown: before, during and after, indicating that the lockdowns due to the global pandemic did not affect extroverted people anxiety as much as it affected introverts. Moreover, it also showed that the level of anxiety of the introverts has become even more intensified even after the lockdown.

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.

Mathematical Misconceptions

The need for developing students' higher order thinking skills is the main indicator in the application of HOTS-based questions in high school mathematics learning. The results of the implementation have not shown satisfactory results. The high level thinking ability of students in Indonesia in Mathematics is still very low. Therefore, a HOTS-based diagnostic test is needed which is able to detect the mathematical misconceptions of high school students as the aim of this study. Based on the research objectives, the method of this study is a qualitative method with research design using the Plomp model research design. The subjects of this study were several students and teachers at a school in Cirebon Regency. The results showed that four HOTS questions could be developed based on three aspects, namely, arithmetic, algebra, and geometry. The problem was developed to detect three forms of misconception, namely, theoretical, classification, and correlational misconceptions. The four questions that have been developed were assessed through the readability test of students and teachers, and CVR and CVI tests were carried out on eight mathematics teachers with valid results. Based on these results it can be concluded that the HOTS questions developed can be implemented for students to detect forms of mathematical misconceptions of high school students.

This study aims to determine the effect of the short video Tik Tok application on the existence of senior high school students. The theory used in this research is the CMC (Computer Mediated Communication) theory which is applied by the media to users which causes mood modification, tolerance, withdrawal, and conflict. The research approach used a quantitative approach using the Rho Spearman correlation analysis. The data collection technique used a questionnaire.The results showed that there was a significant correlation between the use of the Tik Tok application and the existence of high school equivalent students in Pekan Baru Riau. There were 36 respondents in this study using purposive sampling technique. The coefficient value shows a correlation of 0.637 with a significance level of p = 0.000 (p <0.05), meaning that the higher the use of the Tik Tok application, the higher the existence of junior high school students. On the other hand, the lower the use of the Tik Tok application, the lower the existence of high school students. The Tik Tok application shows that it can channel the talents of its users to share hobbies, talents and expertise with everyone. The advantage of Tik Tok that other applications do not have is the completeness of various video features for its users. Although there are social media such as YouTube that offers video features in the form of video sharing channels, YouTube only provides channels for certain users who meet the requirements, not for everyone.

Numerical Expression

This paper aims to investigate numerical expression by Vietnamese speakers of English as a foreign language (EFL). The study identifies and explains the causes of interference errors in expressing number of nouns. A descriptive-cognitive research design was conducted error-oriented investigation of 62 high-school students and 30 employees working in English-speaking companies participating in writing a 45-minute essay for numerical errors from the essays collected. The findings revealed that Vietnamese EFL speakers had difficulty in expressing the number of the entities represented by the nouns due to differences in means and manner of numerical expression in English whose sentences are numerically compulsory and grammatically relevant as opposed to those in Vietnamese whose numerical category is grammatically unimportant, but lexically relevant, and seen with number-neutral nouns or general numbers. Errors also occurred as Vietnamese EFL speakers failed to acquire the count-uncount distinction due in part to differences in perceptualizing the numerical meaning of the entities represented by nouns, ascribing the countability wrong and keeping the same property of countable/uncountable nouns despite having referred to different referents. The paper ended with some pedagogical implications to help Vietnamese EFL speakers improve numerical errors when using English.
