Cooperative learning techniques have been promoted for the development of academic and social competencies. One such technique, Jigsaw, creates cooperation by structuring student interdependence through the learning task, rather than through the grading system. A process and outcome evaluation of Jigsaw was conducted. Eleven teachers of fifth-grade classes received Jigsaw in-service training an...

There has been a growing interest in image jigsaw puzzles with square shaped pieces. A solver takes as input square shaped patches of the same size belonging to an image and attempts to reconstruct the image. The key components of a jigsaw solver are a compatibility metric and an assembly algorithm. A compatibility metric uses the color content of the image patches to identify which pairs of pi...

Authors are requested to select key words from the following list. You may use plurals and adjectives for combinations like absolute pupillary response, centrifugal optic nerve, inter blobs, etc. If key words are needed which do not appear in this list, please underline them. For animal classification the Latin nomenclature should be used. n-mechanism anoxia bird chiasm A-scan antagonism birefr...

Jigsaw patterns, a graphical architecture description notation, will be presented in this paper. The jigsaw patterns shows components and connectors with their interfaces. Connectors are structures or objects implementing the interfaces. Components are structures interacting via the connectors. Each component and connector can be taken as a new system and decomposed. The semantics of the jigsaw...

In this paper, we present a novel encryptionless algorithm to enhance security in transmission of data in networks. The algorithm uses an intuitively simple idea of a “jigsaw puzzle” to break the transformed data into multiple parts where these parts form the pieces of the puzzle. Then these parts are packaged into packets and sent to the receiver. A secure and efficient mechanism is provided t...

Program composition and compositional proof systems have proven them­ selves important for simplifying the design and the verification of programs. The paper presents a version of the jigsaw program composition operator pre­ viously defined in [FFG90, FFG91]. Here, the jigsaw operator is defined as the unification of its components by their most general unifier. The jigsaw operator generalizes ...
