What is Environmental e-Science? An Approach to Public Understanding Joshua Underwood, Rosemary Luckin, Geraldine Fitzpatrick, Yvonne Rogers School of Computer Science & IT, University of Sussex Abstract Our aim is to engage school-aged children in thought about e-Science and in particular two related projects currently being developed by the Equator IRC [1]. Both projects use data from remote sensors and information visualisations to help scientists study complex dynamic systems in the environment, the ecosystem of an Antarctic lake [2] and pollution in a city [3]. Rather than providing descriptions of these, we challenge learners to construct their own understanding through exploration. We use images, questions and deliberate ambiguity [4] to engage learners in a quest to find out what the e-Scientists are doing on the lake and in the city. Learners follow a structured investigative process that guides them through interactive resources, which we are currently developing, and existing websites, and prompts them to think about relevant issues. They also have the freedom to use search and the web to investigate in any direction they feel is appropriate. This work is at an early stage; we are currently prototyping resources and working with teachers to structure the investigative process. 1. Introduction It is increasingly important for scientists to communicate their research to the public, as reflected by EPSRC’s Partnerships for Public Awareness awards [5] and the Sciart initiative [6]. This is especially true for environmental research where issues surrounding climate change are being widely debated within society at large. One vision for environmental science is that data can be captured from arrays of sensors deployed throughout the environment, integrated with other data sources and accessed on a global scale by scientists able to visualise, manipulate and share the data from any location on the planet. The Equator IRC is changing this vision into a reality, to be demonstrated through two environmental science applications: • the study of carbon cycling in an Antarctic lake • the study of pollution monitoring in urban environments Fig 1. What is it? Where is it? Why is it there? Can you find out? Our aim is to promote interest in, and understanding of these two projects amongst school-aged children. For example, by showing how carbon atoms might travel from the urban world to the Antarctic (e.g. how exhaust fumes created in London could end up in a lake in the Antarctic). Part of our plan is to transcend the learners’ normal vision by making what is invisible visible and by bringing the distant near. Learners will be able to hear the Antarctic winds, see microscope organisms and hidden pollution, and measure CO levels in Gower Street or UV light intensity in the Antarctic from the comfort of their classroom or home. Hence, the scientists of the future can begin to experience and consider the consequences of this global interconnectedness. The activities and interactive materials we are developing aim primarily to engage and challenge learners, rather than to explain. Our approach takes de-contextualised and deliberately ambiguous images, words and sounds representing aspects of ongoing environmental eScience work and uses them as clues. Starting from these clues, we challenge learners to create their own understanding of what they see and hear. Currently, we are working on three related strands to this work: a ‘WebQuest’, a televisual ‘channel’ and practical activities relating the investigation of remote environments to the study of the learners’ own local environment. 2. 2.1. Approach A WebQuest WebQuests are a popular form of inquiry-oriented learning activity in which much of the information used by learners is drawn from the Web [7]. A WebQuest typically consists of 1) a scene setting introduction, 2) a challenge or task to solve, 3) a description of the process learners should follow to accomplish the task within which links and references to resources (relevant websites, books, e-mail addresses, message-boards, etc…) are embedded, 4) some guidance on how to organize the information acquired, e.g. guiding questions, a template for a report, or instructions to produce a diagram or poster, and 5) a conclusion that guides learners in evaluating their work and may encourage them to extend the web-based experience into other domains [8]. If well structured this kind of activity is generally popular with learners and provides good opportunities for use and development of cross-curriculum thinking skills (enquiry, information processing, reasoning, evaluation, creative thinking) included in the national curriculum [9]. In situations where the domain material itself is not within the curriculum the opportunity to practise thinking skills may provide a necessary incentive for teachers to use an activity. Our challenge is for learners to find out what the ‘mysterious’ e-Scientists are up to on an Antarctic lake and in London and eventually for them to discover how these two projects might be related. First, small groups of learners are prompted to discuss what they think is shown in a selection of images and how they believe these may be related. For example, for figure 1 they are asked to share and record ideas about what the device might be, where it might be, what it might be for, and how they might find out more. They also add questions they think it would be interesting to find answers to. Learners are then asked to follow a structured investigate process that leads them to interactive versions of the photos online. Moving and clicking the mouse within these interactive photos may reveal hidden details, lead to other viewpoints or link to relevant websites. For example, moving over the wire on the ice reveals sensors below the ice and shows readings for the currently displayed data and time, clicking on a sensor opens a link to a website describing that sensor, clicking on the ‘eye’ takes you to a map view revealing some information about the device’s location (see figure 2). The learners’ activity within these interactive movies causes messages to be sent to the ‘news-ticker’ (blue line at bottom of figure 2), messages here can prompt learners to consider specific questions or to investigate in a particular direction. However, learners are always free to search the web for information and investigate in any direction that they believe to be relevant. Eventually, learners bring together the information they have gathered and produce a report. They are encouraged to evaluate their work using the guidelines provided. When the report is complete, they will have the option to upload it to an online database. This action gives them access to other learners’ reports, which they can then view and evaluate and compare with their own. Figure 2. Interactive photo, showing current wind speed and direction 2.2. Channel The ‘channel’ provides a much less structured route into the same web-based material. Here, images, sounds, and text fade in and out continuously. No action is required on the part of the viewer; she may simply watch the slideshow and perhaps consider the images, text and sounds and how they may be related. However, if she feels sufficiently engaged by any particular passing stimulus she may choose to lean forward and interact by clicking. This action takes her to resources related to the current image. 2.3. Activities Finally, we are developing outlines for possible follow up activities relating the environmental eScience projects to the learners’ world. For example, learners might be asked to collect environmental data about a local pond and compare conditions in the Antarctic lake over the same time frame. Or, they could predict how a pollution map of their own environment would vary over a day. Possibly, they could then plan a methodology for mapping pollution in their own area over a day, borrow CO monitors and collect data to feed into a local pollution visualisation generated online. 3. Discussion This poster has outlined a possible approach to promoting understanding of two specific eScience projects based around prompting learner directed investigation and providing structured support for this, as opposed to providing explanations. This approach to promoting public understanding may also prove appropriate for other projects. However, our work is at an early stage, we are currently prototyping resources and refining guidelines for the investigative process in collaboration with school science teachers [10]. By the end of the project, we plan to have evaluated this approach and hope to have developed an enduring set of web-based resources that are both engaging for learners and useful to teachers.
