This study aims to develop and evaluate a language learning system supported by the ‘flipped jigsaw’ technique, called ‘Flip-J’. This system mainly consists of three functions: (1) the creation of a learning material database, (2) allocation of learning materials, and (3) formation of an expert and jigsaw group. Flip-J was developed as the plugin of the learning management system Moodle, and th...

In the last decade the enterprise of formal semantics has been under attack from several philosophical and linguistic perspectives, and it has certainly suffered from its own scattered state, which hosts quite a variety of paradigms which may seem to be incompatible. It will not do to try and answer the arguments of the critics, because the arguments are often welltaken. The negative conclusion...

The course r...

Jigsaw puzzles [9] and edge-matching puzzles [5] are two ancient types of puzzle, going back to the 1760s and 1890s, respectively. Jigsaw puzzles involve fitting together a given set of pieces (usually via translation and rotation) into a desired shape (usually a rectangle), often revealing a known image or pattern. The pieces are typically squares with a pocket cut out of or a tab attached to ...

This study describes the development of a ubiquitous cooperative learning environment using proposed annotation services, wireless communication devices, and the Jigsaw method of cooperative learning. The purpose of the study is to investigate the potential benefits of studying digital course materials with embedded annotations. The SQ3R study method is introduced during the individual study ph...

We investigate the similarities and differences – in terms of quantitative performance and qualitative behaviors – between how children solve an object manipulation task using mouse-based input versus tangible-based input. This work examines the assumption common in tangible computing that direct physical manipulation is beneficial for certain spatial tasks. We describe an ecologically valid co...

In this paper we study the problem of image representation learning without human annotation. Following the principles of selfsupervision, we build a convolutional neural network (CNN) that can be trained to solve Jigsaw puzzles as a pretext task, which requires no manual labeling, and then later repurposed to solve object classification and detection. To maintain the compatibility across tasks...

Introduction: Today, student-centered methods must be used to train students with professional competency. One of the most valuable methods is Jigsaw (JT). Despite its various positive effects on students’ learning, not all teachers are familiar with Jigsaw. In order to familiarize teachers with this method and encourage them to use it in teaching their students, this article introduces Jigsaw,...

Background: It is essential to keep the reproductive organs and surrounding areas hygienic during menstruation to prevent health issues. Inadequate menstrual self-care knowledge, poor attitudes, and behavior among female adolescents can lead to increased morbidity and other complications among them, such as reproductive tract infections. Aim: This study a...
