Generalization Errors

AbstrakMasih banyak kesalahan yang dilakukan oleh siswa dalam menggeneralisasi pola linier yang disebabkan fokus pada data numerik. Siswa-siswa yang mengalami kesalahan ini penting diberikan kesempatan kembali untuk memperbaiki kesalahan dalam menggeneralisasi pola linier. Untuk itu, tujuan penelitian ini adalah menganalisis proses berpikir siswa dalam memperbaiki kesalahan generalisasi pola linier. Sesuai dengan tujuan penelitian tersebut, maka penelitian ini merupakan penelitian kualitatif deskriptif dengan pendekatan studi kasus terhadap 2 siswa kelas VIII sekolah menengah pertama yang berhasil memperbaiki kesalahan generalisasi pola linier. Hasil penelitian menunjukkan bahwa terdapat dua jenis proses berpikir dalam memperbaiki kesalahan generalisasi pola linier, yaitu memperbaiki dengan menguji dan mencoba, serta memperbaiki dengan mengganti strategi generalisasi. Proses memperbaiki dengan menguji dan mencoba terdiri dari tiga tahap, yaitu: tahap mencari beda, tahap menguji, dan tahap mencoba. Proses memperbaiki dengan mengganti strategi generalisasi terdiri dari tiga tahap, yaitu: tahap mencari beda, tahap mengganti strategi generalisasi, dan tahap menemukan rumus suku ke-n. Cara yang paling efektif untuk memperbaiki kesalahan generalisasi pola linier adalah dengan cara mengganti strategi. Students Thinking Processes in Correcting Errors of Linear Pattern GeneralizationAbstractThere are still many mistakes made by students in generalizing linear patterns due to the focus on numerical data. It is important for students who experience this error to be given another opportunity to correct errors in generalizing linear patterns. For this reason, the purpose of this study is to analyze students' thought processes in correcting errors in the generalization of linear patterns. By the objectives of this study, this research is a descriptive qualitative study with a case study approach to 2 students of class VIII junior high school who succeeded in correcting errors in the generalization of linear patterns. The results showed that there are two types of thought processes in correcting errors in the generalization of linear patterns, namely repairing by testing and trying, and improving by replacing generalization strategies. The process of improving by testing and trying consists of three stages, namely: the stage of finding a difference, the testing stage, and the trying stage. The process of improving by replacing the generalization strategy consists of three stages, namely: the stage of finding a difference, the stage of changing the generalization strategy, and the stage of finding the formula for the nth term. The most effective way to correct linear pattern generalization errors is by changing strategies.

  This research is motivated by learning conditions that are still not optimal, both process and learning outcomes. Therefore, we conducted a research to apply lesson study by using the Cooperative Learning method in Indonesian Language, in writing advertisement, slogans, and posters texts in class VIII of Pasundan 2 Junior High School Bandung. This research is expected to improve learning outcomes, activities and creativities. The research method used is an experimental method. The research subjects were students of Pasundan 2 Bandung Junior High School Class VIII C. This research was an implementation of plan, do and see. The validity of the data is done through triangulation techniques. Based on the results of the study it can be concluded that the application of lesson study using the Cooperative Learning method is carried out in accordance with the stages in the lesson study, namely plan, do and see. Lesson study makes the learning planning process more mature so that in the implementation of learning the model lecturer feels more prepared. Lesson Study can effectively improve the quality of learning, both processes and results. This can be seen from the test results which are tested on the average significant improvement. Likewise in the process, based on the observations made, the activity and creativity of students of Pasundan 2 Junior High School Bandung increased.

Recount text is one of the texts in writing which must be taught and stated in Junior High School curriculum. Some students felt that reading text is boring because the students tend to be very lazy to read the text, so that they are not interested in English lessons. The researchers used group investigation technique as one of alternatives in teaching and learning to develop the material and make students more active and interested in class. The objective of this research is to find out whether teaching using group investigation technique is able to develop the students’ reading in recount text at the eighth grade students of SMP Negeri 17 Kota Serang. The methodology of this research was a quantitative research method by using true experimental design. The study was carried out into two classes, Class VIII E as experimental class, and Class VIII C as control class. The results of the study showed that group investigation was able to develop students’ reading comprehension in recount text. Mean of posttest score of the experimental class (67.31) was higher than the control class (64.18). Based on the statistical analysis using t-test analysis, it showed the value of tcount ≥ ttable = 49.12 ≥ 1.99. It means that (Ha) was accepted and the (H0) was rejected. It can be concluded that group investigation is able to develop students’ reading comprehension in recount text at eighth grade students of SMP Negeri 17 Kota Serang.

Purpose of the study: Knowing the comparison of student learning outcomes in grade 8 at SMP Negeri 2 Muaro Jambi based on the level of work character of the students. Methodology: This study is a quantitative study, the study was conducted at SMP Negeri 2 Muaro Jambi Regency, the sample of the study was students of class VIII, data collection used a hard work questionnaire while the learning outcomes used question instruments. Main Findings: Character education has a positive influence on student learning outcomes. One of the important characters is the character of hard work. Hard work character is a character to use all abilities to achieve maximum results. Based on research conducted on 58 students at State Middle School 2 Muaro Jambi, to determine the relationship between the character of hard work and student learning outcomes. Obtained character hard work has a positive impact on student learning outcomes. So the teacher can help students to be able to foster the character of hard work in each student. Moreover, the current curriculum puts forward character education. The teacher can give the character growth of hard work by providing examples of successful people who have a great will and work hard even though they do not have more ability to realize their dreams. Likewise in Islam, good character education can have an impact on all aspects of activities not only in the academic field but also in the non-academic field. Novelty / Originality of this study: This study is the first to be conducted at a public junior high school in Muaro Jambi district to determine the comparison of student learning outcomes based on student learning outcomes.

Purpose The purpose of this paper is to explore how a foreign invested manufacturing company’s (FIMC) components sourcing process evolves in order to improve its supply chain outcomes in the context of China’s processing trade. Design/methodology/approach Grounded in the theory bases of the international sourcing process and supply chain integration, this study utilizes a single-case-study approach with a small- to medium-sized FIMC engaged in China’s processing trade. Findings This study identifies three stages of the components sourcing process: simple assembly stage, components localization stage and supply chain integration stage. In addition, the case study suggests that the type of processing trade evolves from processing with supplied materials to processing with imported materials as the sourcing process proceeds through the three stages and the internal and external environments change. Originality/value To our knowledge, this paper is the first to focus on an FIMC’s components sourcing process in the context of China’s processing trade. It contributes to a better understanding of how FIMCs progress through the components sourcing process and apply different types of processing trade in China to maximize their supply chain outcomes.
