Mathematical Connection

Mathematical connection is the ability to make connections to understanding mathematical concepts that are associated with contexts outside of mathematics. Various studies revealed that the students' mathematical connection is still low; therefore, this study aims to describe the difficulties of junior high school students in mathematical connection ability. This research is a descriptive qualitative study. The study sample was 52 students from a junior high school in East Flores Regency. The methods used in this study were tests, observations, and interviews. The study results showed that the mathematical connection ability based on the three indicators of connection ability tends to be below. Students did not understand concepts that had been studying; easy to forget concepts, principles and procedures; not used to use concepts, principles and procedures; assume mathematics has nothing to do with other sciences; not accustomed to applying mathematical concepts in everyday life; lack of understanding about the story

The problem raised in this research is that students' ability in making mathematical connections is still relatively low. This is because some of the theories in the learning of teachers still enjoy this way of learning, meaning that the students are only recipient of information without inspiration to active. Therefore, the authors are interested to conduct research by applying an NHT cooperative model setting to improve mathematical connection ability of junior high school students. This study aims to determine whether the knowledge of mathematical connections of junior high school students using learning methodology is better than junior high school students using ordinary learning. This research was conducted in SMP Krida Utama Padalarang Class VII, with research method the research used is quasi-experimental method. The sample of this research is taken two classes namely class VII A as experiment class and class VII B as control class. The research instrument is a set of mathematical connection test questions consisting of 5 test questions, and then tested by using a statistical test of differential. Based on the results of research and data processing, the authors conclude that the ability of mathematical connections of junior high school students whose learning using open-ended approach with learning model setting NHT type cooperative learning is better than the mathematical connection ability of junior high school students whose learning using ordinary learning.

This research aims to describe the mathematical connection in problem solving. Metode of qualitative research. The subject of this study were two ninth graders of junior high school in with a purposive technique. The research instrument was a mathematical connection test problem. The data analysis technique uses three stages, namely data reduction, data presentation, and drawing conclusions. The results showed that students complate aspects of mathematical connections, namely: Aspects of mathematical connections in mathematical problems such as: Students understand the relationship between existing mathematical topics by writing down the equation model as ideas of the problems. Students are able to find the relationship between existing procedures and other procedures in representation with the equivalent concept shown by writing the two-variable linear system material equation. Students apply the relationship between mathematics, and between mathematical material with mathematical material by finding the value of equations. Students are able to use mathematical connections with mathematics or other fields of science using mathematics with economics to determine the number of purchases with capital, and aspects of mathematical connections with everyday life, namely; Students use procedures and concepts from one another according to the question data. The ability of students to use mathematics in everyday life in the context of buying and selling using capital, amount, profit. So, as a whole the mathematical connection ability of junior high school students complate the indicators and into the high connection category.

Helping junior high school students to use calculators and computers for problem solving and investigating real-life situations is an objective of the junior high school mathematics curriculum in Ghana. Ironically, there is a technological drought in junior high school mathematics instruction in Ghana, with a suspicion that mathematics teachers’ competency in the use of calculators for teaching may be the source of this lack of use. This study sought to establish a correlation between junior high school mathematics teachers’ competence and the motivation supporting the use of calculators in teaching.  A descriptive survey comprising of a test and questionnaire was used to collect data from junior high school mathematics teachers in an educational district in Ghana. Teacher characteristics such as educational attainment, age, and gender in relation to teachers’ competency in the use of calculators were discussed in the study. The results showed that about 70% of the teachers exhibited a low level of calculator competence. Besides, novice teachers outperformed expert teachers in the calculator competency-based test. Additionally, mathematics teachers’ enthusiasm for using calculators in teaching was directly associated with the teachers’ level of competency. The findings may send a signal to stakeholders in their efforts to revising the Ghana JHS curriculum in order to actualize the curriculum desire for the integration of technology in the teaching and learning of JHS mathematics.
