This study explored the autonomy of advanced English as a Foreign Language (EFL) learners in reading comprehension through scaffolding and jigsaw in computer-assisted and conventional contexts. After being homogenized through the reading section of DIALANG proficiency test, a total of 80 female advanced EFL learners with the age range of 21 to 45 were selected as the participants of the study. ...

We review the first iteration of an Alternate Reality Game (ARG) designed to engage middle school students in the interpretive process behind history and the mathematical roots of cryptography and cartography. Building from the core characteristic of ARGs as collaborative sense-making systems, we sought to integrate elements of effective cooperative learning environments, such as positive inter...

This paper presents novel techniques and metaphors for on-demand visual workspaces in everyday office environments, providing space-efficient, flexible and highly interactive graphical user interfaces using projected displays. For increased resolution, contents personalization and interactive visualization, the users can augment the large-scale projections with dynamic high-resolution foveal en...

The Ougi immersive programming system employs abstract data visualization and manipulations utilizing virtual reality technologies. Its multimodal interfaces allow one to edit a program, to control its execution and to debug the program by direct manipulation and hand gestures in an immersive virtual environment. Ougi uses both textual and graphical representations and supports a subset of the ...

Coordinating growth and communication between adjacent cells is a critical yet poorly understood aspect of tissue development and organ morphogenesis. We report a Rho GTPase signaling network underlying the jigsaw puzzle appearance of Arabidopsis leaf pavement cells, in which localized outgrowth in one cell is coordinated with localized inhibition of outgrowth of the adjacent cell to form inter...

In the nucleus of eukaryotic cells, histone proteins organize the linear genome into a functional and hierarchical architecture. In this paper, we use the crystal structures of the nucleosome core particle, B-DNA and the globular domain of H5 linker histone to build the first all-atom model of compact chromatin fibers. In this 3D jigsaw puzzle, DNA bending is achieved by solving an inverse kine...

Plant leaf epidermal cells exhibit a jigsaw puzzle-like pattern that is generated by interdigitation of the cell wall during leaf development. The contribution of two ROP GTPases, ROP2 and ROP6, to the cytoskeletal dynamics that regulate epidermal cell wall interdigitation has already been examined; however, how interactions between these molecules result in pattern formation remains to be eluc...
