Abstract

The lack of Indonesian students achievement in the international assessment is due to several factors. Students are not familiar with the problems requiring reasoning, in particular the proportional reasoning. This research aims to identify the distribution and the Level of Cognitive Demands (LCD) of the proportional reasoning problems found in the Year 7 and Year 8 mathematics textbooks based on the 2013 curriculum (revised edition 2014). The data collection was conducted by identifying the proportional reasoning problems found in the whole chapters of the textbooks which are then analysed and classified using the Smiths and Stein’s criteria of LCD (1998). The results reveal that the proportional reasoning problems were only found in the three of 17 chapters namely ratio and proportion, rectangle and triangle, and Pythagorean Theorem, which represent different LCD including Lower-LCD (Low-M and Low-P) and Higher-LCD (High-P). Out of 69 proportional reasoning problem found in the textbooks, the percentage of higher-LCD problems (n=29 ; 42.03%) is less than lower-LCD (n=40;57.97%). In addition, the higher-LCD problems found were only the high-P type. None was found to meet the requirement of High-DM demanding students to conduct ‘doing mathematics’, complex approach and self-monitoring or self regulation of students’ cognitive process. It is recommended that the proportional reasoning problems, including some High-DM problems, should be provided in each topic in Indonesian mathematics textbooks.DOI: http://dx.doi.org/10.22342/jme.9.1.4145.55-68

Abstract

Student mastery of the basic arithmetic operations of mathematics is still low, especially for students who received school education background before heterogens. This research was conducted to determine the type of error that made the students in doing mathematics basic arithmetic operations, increase students' ability to perform basic arithmetic operations through the implementation of the mathematics matriculation, and suitability scores obtained by students with a score of predetermined targets. This research is a descriptive qualitative research subjects were 27 students of class X SMK 2 Langsa. Data were analyzed using the concept of Miles and Huberman: includes the step of data reduction, data presentation, and conclusion. The results showed that the errors made by the students in solving basic math arithmetic operations are procedural and conceptual errors. Procedural errors do end results is a mistake, an error in the operations of addition, subtraction, multiplication, and division of integers. Conceptual error committed is a mistake to equate the denominator in the operation of addition and subtraction of fractions, simplifying error in root form, and errors in rationalizing the denominator.

Abstract

The engagement of students' initiative in designing the floor plan has received less attention from the teacher. Student engagement can be seen from the student's initiative in designing a floor plan during learning. One strategy that can be used is Science, Technology, Engineering, and Mathematics (STEM). STEM integrates science, technology, engineering, and mathematics. This study aimed to describe the students' initiative in designing floor plans through STEM at one of the junior high schools in Banda Aceh, Indonesia. This is descriptive qualitative research. The subjects of this study were seven Year 7 students. Data collection was carried out using observation sheets. Student initiatives in this study were measured by eight indicators: trying to do their job perfectly and seriously, not doing it carelessly, actively participating in discussions, doing more than assigned work, not being communicative, asking questions to get more information, raising hands before responding to questions or expressing opinions, referring to his/her dictionary, encyclopedia, or other references for information, and meeting teachers to discuss learning material before or after school. The results showed that the students' initiative increased in designing floor plans through STEM. This can be seen from students who meet the eight indicators of the initiative. Thus, it can be concluded that all indicators in this study were fulfilled so that students can complete project assignments well.
