- W314504962 abstract "Helping students to develop a cognitive and intuitive feel for the different temporal and spatial scales of processes through which the rock record is assembled is a primary goal of geoscience teaching. SedWorks is a 3-D virtual geoscience world that integrates both quantitative modelling and field-based studies into one interactive package. The program aims to help students acquire scientific content, cultivate critical thinking skills, and hone their problem solving ability, while also providing them with the opportunity to practice the activities undertaken by professional earth scientists. SedWorks is built upon a game development platform used for constructing interactive 3-D applications. Initially the software has been developed for teaching the sedimentology component of a Geoscience degree and consists of a series of continents or land masses each possessing sedimentary environments which the students visit on virtual field trips. The students are able to interact with the software to collect virtual field data from both the modern environment and the stratigraphic record, and to formulate hypotheses based on their observations which they can test through virtual physical experimentation within the program. The program is modular in design in order to enhance its adaptability and to allow scientific content to be updated so that the knowledge and skills acquired are at the cutting edge.We will present an example module in which students undertake a virtual field study of a 2-km long stretch of a river to observe how sediment is transported and deposited. On entering the field area students are able to observe different bedforms in different parts of the river as they move up- and down-stream, as well as in and out of the river. As they explore, students discover ?hot spots? at which particular tools become available to them. This includes tools for measuring the physical parameters of the flow and sediment bed (e.g. velocity, depth, grain size, bed slope), a zoom-in/zoom-out function (to increase or decrease the resolution of the observations, e.g. zoom-in to observe the motion of individual grains on the bed) and a sectioning tool (to allow students to cut a cross-section through a bedform to observe the sedimentary structure being created). Students are encouraged to make notes of their observations in a field notebook, as they would in the real world. Based on their observations, students form hypotheses about the relationship between the physical attributes of the flow and the way in which sediment is transported, bedforms produced and sedimentary structures created. They are able to test these hypotheses using a virtual flume in an experimental field station, conveniently located within the field area. Concepts investigated by the students during the virtual field study include controls on bedload sediment transport, bedform phase diagrams, flow structure within channels (and its effect on sediment erosion and deposition), fluvial facies models and controls on facies architecture, and landscape evolution over different temporal and spatial scales." @default.
