Abstract

The facility layout design problem is concerned with determining the location of a number of facilities which optimises a prescribed objective such as profit, cost, or distance. This problem arises in many applications; for example, in design of buildings and in plant layout design. Most approaches for solving this problem are heuristic in nature and based on graph theoretic concepts. Graph theoretically, when the objective is to maximize profit, the facility layout design problem is to determine, in a given edge weighted graph G, a maximum weight planar sub graph. In this paper, a new heuristic based on graph theoretic concepts is presented. A comparative analysis based on 3600 random test problems demonstrates the value of this algorithm. Key words:  Heuristic, maximum planar graph, computer, facility layout design.

Abstract

Geometry has abstract notions to be learnt so that all those notions cannot be just transferred into students’ mind like a bunch of information that should be memorized. Students need to construct those concepts during their learning process. This process of knowledge construction can be considered as an abstraction process. This study aimed to qualitatively compare abstraction process of students who learned the topic of triangle in conventional method and in van Hiele model of teaching aided by Geometers’ sketchpad. Subjects of this study were junior high school students in grade 7. This is a qualitative study with grounded theory design. Data were collected through classroom observation, test, and task-based interview. Results of the study show that theoretical abstraction processes tend to dominate classrom with conventional method of teaching while classroom with van Hiele model of teaching aided by Geometers’ sketchpad accommodated empirical abstraction process of the students.

Abstract

This paper reports some results of a research attempted to cultivate students' mathematical reasoning ability (MRA) by means of implementing problem-based learning (PBL) model. The population was upper secondary students of public schools in Bandung. Cluster sampling technique applied to take sample of amount 158 students from middle-level schools. Data were teachers' assessment on students’ performance in last two months, prior mathematical knowledge (PMK) and MRA test, observations, and interview. Two-factors ANOVA then used to analyze the data. Findings showed that overall students in PBL-classroom achieved better MRA than their counterparts in conventional one though the category in both classrooms was low. Interaction between PBL and PMK factor towards MRA did not emerge. Most part of the participants viewed PBL neither positive nor negative. On the contrary, they assessed that the tasks given made and demanded them thinking and learning more actively than ever. The findings showed adopting PBL in schools to facilitate students getting their higher order thinking skills is a reasonable choice, especially schools having middle or high ability students.Keywords: problem-based learning (PBL), mathematical reasoning ability

Abstract

One of skills which must be achieved by mathematics pre-service teachers is the basic skills of teaching mathematics. By having these skills, the pre-service teachers are expected to be able to become qualified teachers of the field they are going to have. However, there are still many mathematics pre-service teachers and mathematics teachers who haven’t achieved good basic skills of teaching mathematics. This was one of many factors that cause students’ low achievement in math. This study aims at solving the problem by developing learning materials with Search-Solve-Create-Share strategy to enhance the pre-service teachers’ basic skills of teaching mathematics. The research method used in this study is modified research and development method. In a nutshell, this study provides a significant contribution towards research in the mathematics education field particularly in producing suitable learning materials to enhance the pre-service teachers’ basic skills of teaching mathematics. Keywords: Basic Skills of Teaching Mathematics, Learning Material, Search-Solve-Create-Share
