ABSTRACT
 One of the skills 21st century that must be possessed is ability to collaborate or work together. Cooperation means working together achieve same goal. In context learning, cooperation referred as an activity aimed at group between friends who have different opinions, but these differences opinion can put This study aims determine application jigsaw-type cooperative learning and ...

this paper examines the theoretical rationales and practical aspects of task-based language teaching (tblt) with particular reference to research findings in efl/esl contexts. the definitional scope of the term ‘task’, polarizations in terms of task vs. non-task, and its relation to different language teaching approaches have engendered conceptual and methodological ambiguities.  moreover, fact...

Porcine reproductive and respiratory syndrome virus (PRRSV) is the causative agent of the, probably, most economically important disease for pig industry worldwide. This disease, characterised by producing failure in sows problems growing pigs, appeared late 1980s United States Canada. Since its appearance, strains capable higher mortality rates as well greater severity clinical signs lesions t...

In a recent work, Mossel and Ross considered the shotgun assembly problem for a random jigsaw puzzle. Their model consists of a puzzle an n×n grid, where each vertex is viewed as a center of a piece. They assume that each of the four edges adjacent to a vertex, is assigned one of q colors (corresponding to ”jigs”, or cut shapes) uniformly at random. Mossel and Ross asked: how large should q = q...

The jigsaw puzzle is a well known problem, which many encounter during childhood. Given a set of parts, one needs to reconstruct the original image. This problem is known to be NP-complete. In this paper I describe a greedy solver with several improvements. Before discussing the general idea and improvements, I will discuss some important known metrics that will help us clarify the solver algor...

We speed up the screening of a computer image compressed as an iterated function system (IFS) of affine transformations w1, . . ., wN . The idea is to avoid applying a given map to a given point if nothing new would be obtained. Let w(x, y) be the result of applying transformation w to pixel coordinates (x, y) then rounding to the nearest integer pair, say (u, v). Then the w-jigsaw pieces w−1(u...

A random jigsaw puzzle is constructed by arranging n2 square pieces into an n× n grid and assigning to each edge of a piece one of q available colours uniformly at random, with the restriction that touching edges receive the same colour. We show that if q = o(n) then with high probability such a puzzle does not have a unique solution, while if q ≥ n1+ε for any constant ε > 0 then the solution i...

The ability to think analytically is one of the competencies that must be possessed by students. Analytical thinking a involves process breaking down material into small pieces and determining relationships overall structure. Teachers are required develop learning model more innovative fun in order stimulate students' analytical using JIGSAW STAD models further hone their skills. purpose this s...
