Let G be a graph with a set of vertices V(G) and a set of edges E(G). The distance from vertex u to vertex v in G, denoted by d(u, v), is the length of the shortest path from vertex u to v. The eccentricity of vertex u in graph G is the maximum distance from vertex u to any other vertices in G, denoted by e(u). Vertex v is an eccentric vertex from u if d(u, v) = e(u). The eccentric digraph ED(G) of a graph G is a graph that has the same set of vertices as G, and there is an arc (directed edge) joining vertex u to v if v is an eccentric vertex from u. In this paper, we determine the eccentric digraph of a class of graph called the cocktail party graph and hypercube.

Abstract: The aim of the research was to determine the effect of cooperatif learning models viewed from the attitude of students. The learning model compared were TAICTL, TAI and direct instruction. This was quasiexperimental research designed by factorial 3x3. The population was 8th grade students of junior high school even semester academic year 2013/2014 in Magetan regency. The sample was taken by using stratified cluster random sampling. Total sample was 231 students, consisted of 77 students as TAICTL class, 78 students as TAI class, and 76 students as direct instruction class. Hypothesis testing was performed using twoway analysis of variance with unequal cells. Based on the results of hypothesis testing, it is concluded that: (1) students learns using TAICTL and TAI had better achievement than students learnt using direct instruction, students learnt using TAICTL had better achievement than students learnt using TAIÂ (2) positive attitude students had better achievement than those of neutral and negative attitudestudents, neutral attitude students had better achievement than negative attitude students (3) for TAICTL and TAI, students with positive attitude had better achievement than neutral and negative attitude, however neutral attitude students had the same achievement as negative attitude students, for direct instruction, positive attitude students had the same achievement as neutral attitude students, meanwhile positive attitude students had better achievement than negative attitudeand students with neutral attitude had the same achievement as negative attitude students (4) for Â positive attitude students, students learnt using TAICTL had the same achievement as students learnt using TAI, meanwhile students learnt using TAICTL and TAI had better achievement than students learnt using direct instruction, for neutral and negative attitude students, students learnt using TAICTL, TAI, and direct instruction had the same achievement.Keywords: TAICTL, TAI, Direct Instruction, AttitudeÂ
