<p><strong>Abstract.</strong> In this article, we present a method for visualizing multi-dimensional spatio-temporal data in an interactive web-based geovisualization. Our case study focuses on publicly available weather data in Germany. After processing the data with Python and desktop GIS, we integrated the data as web services in a browser-based application. This application displays several weather parameters with different types of visualisations, such as static maps, animated maps and charts. The usability of the web-based geovisualization was evaluated with a free-examination and a goal-directed task, using eye-tracking analysis. The evaluation focused on the question how people use static maps, animated maps and charts, dependent on different tasks. The results suggest that visualization elements such as animated maps, static maps and charts are particularly useful for certain types of tasks, and that more answering time correlates with less accurate answers.</p>

<p>Self-directed professional learning is distinct from the traditional approach of directed professional development. The introduction of the Internet into Indonesian society provides the opportunity for teachers to use digital tools for their teaching and to access professional learning without attending mandated professional development. An emerging phenomenon in Indonesia is the establishment and use of Google Education Groups (GEGs) for professional learning about the use of educational technology (ed-tech) in the schooling sector. Two research questions guided the examination of Indonesian educators’ experiences of GEGs: (1) how do Indonesian educators participate in the GEGs for ed-tech professional learning? and (2) how do the GEGs function to enable Indonesian educators’ ed-tech professional learning? Collective case study methodology was applied, and three Google Education Groups were examined, one from a metropolitan area, one from an urban area and the third from a rural context. In each case study, the leader of the group and three group members with varying levels of online engagement were interviewed and online forum conversations were examined. Data were analysed using Stake’s method of categorical aggregation leading to within-case assertions and cross-case analysis. A social cognitive perspective was used as a framework to analyse and interpret findings. It was found that the Indonesian educators had an agentic approach to professional learning, which was context-dependent with three major interrelated aspects: the regional-technological environment as context, the individuals as agentic learners, and the connectedness as social learners enabled meaningful learning experiences. The regional-technological environment influenced how the GEGs functioned. The Metropolitan group was innovative and collaborative, focusing on the use of web-based tools to improve productivity of ed-tech practices. The Urban group aimed to explore how they could use web-based tools to improve efficiency through paperless classroom practices and school administration. The Rural group sought to use of web-based tools for simple teaching and learning practices within a context of low bandwidth and limited ICT infrastructure. In addition, certain conditions that support online collaboration and factors that can minimise and optimise ed-tech learning opportunities are identified. Participants overcame limitations and constraints by enacting agency and developing social connectedness in learning through the groups. The group leadership positions were voluntary and found to be driven by a desire to share expertise and practices that support, inspire, and empower others rather than about gaining positional authority. Participation in online informal groups such as Google Education Groups appears to be a supportive method of professional learning that facilitates agentic and experiential learning about the use of educational technology in Indonesia. This model can enhance professional learning opportunities for Indonesian educators. It can also be implemented into the design of government-supported ed-tech PD programmes, to create an empowering and safe learning environment that can optimise their potential in learning and improve practice.</p>

Using XML as the source format for authoring technical publications creates opportunities to develop tools that provide analysis, author guidance, and visualization. This case study describes two web applications that take advantage of the XML source format of documents. The applications provide a browser-based tool for technical writers and editors in a 100-person documentation department of a software company. Compared to desktop tools, the web applications are more convenient for users and less affected by hard-to-predict inconsistencies among users' computers. One application analyzes file dependencies and produces custom reports that facilitate reorganizing files. The other helps authors visualize their network of topics in their documentation sets. Both applications rely on the XQuery language and its RESTXQ web API. The visualization application also uses JavaScript, including the powerful jQuery and D3 libraries. After discussing what the applications do and why, this paper describes some architectural highlights, including how the different technologies fit together and exchange data.

This case study examines the Web Electronic Service framework for a University in Australia. The department is in the process of developing and implementing a Web-based e-service system. The user experience to use e-services requires insight into the attributes that shape the experience variable. The descriptive data about the attributes that form the experience variable is provided in this study.

Bioinformatics is an emerging area of interest for many researchers and scientists. It has unlimited applications in many areas. The most important application of this is to know about genes, et cetera. But nowadays, research has also started in the emerging areas of network security and threats using bioinformatics. In the present scenario, we are highly dependent on Internet. The Web has invited different people from different backgrounds to work together sitting at far places. And to fulfill the needs of the interested and involved people, lots of Web based tools have been developed, and many others are being developed. In this chapter, the area of bioinformatics has been introduced along with its applications, Web, developed Web based tools, and a case study of one such tool.
