Cross-cultural language learning and web design complexity

Accepting the fact that culture and language are interrelated in second language learning (SLL), the web sites should be designed to integrate with the cultural aspects. Yet many SLL web sites fail to integrate with the cultural aspects and/or focus on language acquisition only. This study identified three issues: (1) anthropologists’ cultural models mostly adopted in cross-cultural web user interface have been superficially used; (2) web designers deal with culture as a fixed one which needs to be modeled into interface design elements, so (3) there is a need for a communication framework between educators and design practitioners, which can be utilized in web design processes. This paper discusses what anthropology can contribute to language learning, mediated through web design processes and suggests a cultural user experience framework for web-based SLL by presenting an exemplary matrix. To evaluate the effectiveness of the framework, the key stakeholders (learners, teachers, and designers) participated in a case scenario-based evaluation. The result shows a high possibility that the framework can enhance the effective communication and collaboration for the cultural integration.

Characterizing navigation in interactive learning environments

Interactive learning environments (ILEs) are increasingly used to support and enhance instruction and learning experiences. ILEs maintain and display information, allowing learners to interact with this information. One important method of interacting with information is navigation. Often, learners are required to navigate through the information space of an ILE, a process which can be quite difficult and cognitively exacting as the information space becomes very large and complex. Proper design can make this process less exacting and, at the same time, facilitate better learning of the information space. However, this is not easy to do, especially for ILEs. Frameworks can assist in the effective analysis and design of interactive environments. However, there is lack of conceptual frameworks for guiding the analysis and design of navigation in ILEs. This paper tries to address this issue by presenting a framework which can be used to characterize navigation within ILEs. To create this framework, this paper brings together research from various disciplines, such as human-computer interaction design, educational multimedia design, cognitive technologies and learning sciences. This framework prescribes a three-stage process for designing and analyzing navigation: 1. content structuring; 2. information navigation modeling; 3. interface presentation structuring. By bringing these three stages together, it is intended to provide a conceptual framework to assist and guide designers in the proper analysis and design of navigation in ILEs.

Beyond Framing

Visual news media's framing has been well studied; however, production factors and cultural conditions involved in photographer–subject interactions have attracted less scholarly attention although they are no less influential in determining the depiction. Guided by social constructionism theory, in-depth interviews with staff photojournalists at a daily community newspaper in the Midwest and an analysis of their work revealed 22 variables that impact how and why images look the way they do. Photojournalists have complete control of only two of these variables, share partial control of 13, but have no control over the remaining seven. The photographers also shared insights into how to improve their journalism's verisimilitude when dealing with reactive subjects. The results support concepts of social constructionism that the subjects of photographs are most comfortable with photographers who share similar characteristics, but that some characteristics can have greater influence. The results also highlight areas where photographers might focus in pursuit of authenticity in journalistic photographs.     

Seeing Library Data: A Prototype Data Visualization Application for Librarians

Visualizations can add value to raw library data. Tools that programmatically make such visualizations interactive can further increase the value of these data by giving librarians visual tools to analyze their datasets. To demonstrate these benefits, Kingsborough Community College Library built SeeCollections (http://b7jl.org/seecollections), a Web application that visualizes the libraries’ collections of books and e-books. This article discusses the how SeeCollections gathers data from Kingsborough's discovery layer API (Application Programming Interface) and transforms these data to create visualizations for the Web. SeeCollections is a lightweight, proof-of-concept data application based on a vendor API. API data are often accessible in academic libraries but are frequently underutilized. SeeCollections was built to demonstrate the immediate value of these API data sources to Kingsborough librarians by providing a visual interface to discovery layer data. Keeping in mind the broader literature on data visualization, this article will explore how SeeCollections was built.
