Interval Type

In this paper, a two-stage method has been proposed for solving Fuzzy Multi-objective Linear Programming Problem (FMOLPP) with Interval Type-2 Triangular Fuzzy Numbers (IT2TFNs) as its coefficients. In the first stage of problem solving, the imprecise nature of the problem has been handled. All technological coefficients given by IT2TFNs are first converted to a closed interval and then the objectives are made crisp by reducing a closed interval into a crisp number and constraints are made crisp by using the concept of acceptability index. The amount by which a specific constraint can be relaxed is decided by the decision maker and thus the problem reduces to a crisp multi-objective linear programming problem (MOLPP). In the second stage of problem solving, the multi-objective nature of the problem is handled by using fuzzy mathematical programming approach. In order to explain the methodology, two numerical examples of the proposed methodology in Production planning and Diet planning problems have also been worked out in this paper.

This study aims to describe and analyze students' mathematical problem solving abilities based on theory of APOS (Action, Peocess, Object, Schema) in terms of Field Dependent and Field Independent Cognitive Style. It is descriptive research with qualitative approach. The research subjects are 34 students in class XI MIPA 1 SMA Nurul Islam Jember, they are grouped on cognitive style, they are 24 students having field independent cognitive style and 10 students having field dependent cognitive style. The method of data collection use a GEFT (Group Embedded Figure Test), test of problem solving abilities, , and interviews. The results of the data analysis of the problem solving ability test and interviews showed that at the action stage, students with the independent field cognitive style (FI) tended to be able to explain the meaning and information on the questions even though they did not write down what they knew. Students with the field dependent cognitive style (FD) tend to be able to write down the information contained in the questions, but have difficulty explaining the meaning of the questions. At the process stage, FI and FD students are able to model and explain the stages well, but FD still has errors in the resulting mathematical model. At the object stage, FI students tend to work on questions freely, while FD students tend to work on questions in detail or are fixated on completely arranged steps, FD students also have difficulty in explaining back the results of their work. At the schema stage, FI and FD students tend to be able to explain how to use the information contained at the object stage to be used at the schema stage. In general, students with a field independent cognitive style in solving mathematical problems tend to be free or not fixated on complete and detailed steps, and have an analytical nature, so they are able to sort out the important information contained in the questions. Students with a field dependent cognitive style in solving math problems tend to be bound or fixated with steps that are arranged in a complete and detailed manner. Keywords: mathematics problem solving, APOS theory, cognitive style

The Difference

Based on the experience of the researchers taught the subject of Economic Mathematics many students who have not been able to solve the problem solving. One alternative that can be used to solve the problem is by using Polya steps. When solving a mathematical problem, each student has a different way of thinking. The difference is possible because of differences in student cognitive style. The cognitive styles used in this research are Field Independent cognitive style and Field Dependent cognitive style. The material chosen in this research is the demand function, the Bid Function, the Savings Function and the Taxation Function. This research is a descriptive research with qualitative approach which aims to describe the problem solving ability of student mathematics using Polya steps in terms of cognitive style of FI and FD. Subjects in this research are students of VI semester of Mathematics Education Program. Technique of taking research subject is by purposive sample. The results showed that FI subject understood the problem well. In the planning step, the FI subject can analyze the information received. Subjects use previously learned information and solve problem-solving given to the problem as planned and check back on each question. The subject of FD can not receive information and understand the problems that exist in the problem and can not process information/do not understand the purpose of the problem. In the planning step, the subject of FD is unable to think how to solve the problem and is not accustomed to rechecking

The aim of this research is to describe junior high school students’ problem solving profile in the Pythagoras Theorem problem based on the cognitive styles of FI and FD. The subjects of this research consisting of two subjects FI and two subjects FD in VIII H SMP Negeri 2 Lumajang. Instruments used: cognitive style tests (GEFT), Pythagoras Theorem problem solving tests, and interview guideline. Problem-solving indicators that be used is Polya's problem solving steps: understanding the problem, devise a plan, carry out the plan, and looking back. The results of this study is the FI subject is better than the FD subject. The FI subject understand the problem very well, arranging a solution plan well, implementing a plan properly, and looking back well. Different from previous research, subject FI make error even though not any Polya’s step. Nevertheless, The FD subjects are categorized as lacking in the step of understanding the problem, devising a plan with deficient category, implementing the plan without looking back on the solution, so it is categorized as lacking and errors emerged at almost every step. Some errors in problem solving showed by FI and FD subjects, so for further research need to analyses errors and the other cognitive style.
