Abstract

Difficulties in mathematical language and representation were the dominant difficulties in solving word problems for students in elementary school. The research aims to analyze students' mathematical language and representation difficulties when solving word problems. The research subjects were 114 fifth-grade elementary school students selected using a purposive sampling technique with different mathematical abilities. The research was conducted at an elementary school in Sumbawa District, West Nusa Tenggara, Indonesia. Data collection techniques included tests, questionnaires, and interviews. The research results show that students' difficulties in mathematical language were dominant indicators of sentences. Students had difficulties in mathematical representation indicators, which were dominant in symbols. The factors that cause difficulty for high, middle, and lower ability students are unaccustomed to solving word problems and using problem-solving procedures, difficulty with concepts, difficulty with reasoning, difficulty understanding what is known and what is being asked, not being careful in reading the problem, and difficulty with long sentences. Student word problem-solving is in the low category.

Abstract

This research investigates students' mathematical language difficulties in solving word problems in elementary school. This research method uses a descriptive with a qualitative approach. The research subjects were 52 fifth-grade elementary school students using a purposive sampling technique with students of different abilities, namely upper, middle and lower abilities. Data collection techniques included triangulation data sources through tests, interviews, and questionnaires, as well as data analysis techniques, namely data reduction, data presentation, and drawing conclusions. Research findings show that students with upper and middle ability problem solving are in the "low" category, and students with lower ability are in the "very low" category. Students' difficulties in mathematical language are most dominant in sentence indicators. The dominant error is that students do not write down what they know and ask. The influencing factors are internal factors: students are not used to reading long questions, so word problems are more difficult than telling stories directly; not careful; difficulty connecting to concepts (creating models); and students focus on mathematical symbols, not the language of the problem. External factors: Students are rarely introduced to word problems; the teacher does not use a special approach to word problems material learning; the language in the word problems is not yet communicative and authentic (based on real events, there are actors, settings and themes that are liked); and the environment is less supportive. This research concludes that mathematics word problems have a language structure from informal to formal (symbols) arranged in words, phrases, sentences and discourse. Word problems must be designed with communicative and more authentic language, more continuous learning of word problems is provided in each learning topic, and the learning environment at school and home must be mutually supportive.

Abstract

this study aims to describe the application of cooperative learning model picture and picture by using the media flashcard can improve student learning outcomes in mathematics class VIIA SMPN 3 Sikur the academic year 2016/2017 in the subject matter fractions. A common issue is the mathematics subjects are still considered abstract, and difficult. The use of the model and the use of media is less precise, less varied. Thus, the lack of attention that adversely affects the student learning outcomes. The use of appropriate methods and media are expected to improve learning outcomes. The use of the learning model type of picture and picture by using the media flashcard is one of the solutions offered to solve the problem. This research is a classroom action research (PTK) is conducted in two cycles. Types of data used are: Qualitative sheet teacher observation and student observation sheet, quantitative data obtained from the results of student evaluation tests given at the end of each cycle. The results showed that there was an increase in student learning outcomes, where the results of the first cycle with the classical percentage of 70% and the second cycle peresentase by 87%. Thus, it can be concluded that the application of cooperative learning model picture and picture by using the media flashcard can improve student learning outcomes class VIIA SMPN 3 Sikur in Academic Year 2016/2017.

Abstract

This study was aimed to find whether or notthe effectiveness of mother tongue have a significant effect towards students’ memory and motivation in learning mathematics at the eight students of SMP Negeri 1 Ropang. In this research, the researcher used quasy experimental research method. The population were all of the eight students at SMP Negeri 1 Ropang. the researcher divided into two classes. A class is as control group was taught by using Bahasa and B class is as experimental group was taught by using mother tongue technique. The data was obtained through pretest, posttest and laerning motivation questionnaires. The first students’ ability was seen from the result of pretest was calculated by using normality test meanwhile the last students’ ability was seen by using posttest. Before using t-test, the researcher used posttest to calculate normality test with chi-quadrate after that the researcher gave the t-test. The result of the research showed that mean score of experimental group was 42 to be 73 meanwhile control group was 25 to be 60. Therefore, the result of t-tes (0,735 )was smaller than t- table (2,017). It means that Ho was accepted and Ha was rejected. So, the researcher can concluded the effectiveness of mother tongue technique was not effective toward students’ memory and motivation in learning mathematics at the eight students of SMP Negeri 1 Ropang in academic year 2016/2017.

Abstract

Habits of teachers in only use conventional teaching methods in teaching and learning mathematics cause less enthusiastic students to follow the lessons. Therefore, teachers are required to select a model appropriate learning characteristics of students and the material being taught. Thus, students will more easily understand the material. This study aims to determine the effect ofapproach SAVI (Somatic, Visual, Intelectual) the on communication skills of mathematics students of class VII MTs. NW Men 2016/2017 school year. population in this study consisted of 327 students and is where the study sample consisted of two classes of class VII B (experiment) and VII C (control). Determination of the experimental class and control class is determined by Probability Sampling and obtained class VII B as an experimental class while the class VII C as the control class. The results showed the average value of 61.56 while the value - average for the control class 45.17. While Test-T to the achievement of the control class experiment belajarkelas obtained tcount > ttable (3.285> 2.002) that concluded the application of the model approach SAVI (Somatic, Auditory, Visual, Intellectual) affect the ability of students' mathematical communication VII MTs. NW Men Narmada in the academic year 2016/2017.
