  1. This project was led by Esri France along with the Joseph Fourier University, the Laboratory of Informatics of Grenoble, the « Observatoire des Sciences de l' Univers de Grenoble” «Proposal of a semi-autonomous workshop to learn GIS in Geosciences» An introduction to multicriteria spatial analysis R.Balzarini LIG - ESRI France 2011

  3. 1. The assessment For the last 10 years, geosciences professions have been changing their practices including new technologies and new proficiencies of geomatics sciences. Geological skills and knowledge required today by the labour market evolve but, paradoxically, geosciences in France higher education curriculums don’t seem to answer to these new needs. • Questions : • What learning system would equip students with the requisite skills to use GIS and still contribute to improving their general geosciences education? • 2. How could such a system be generalized to other territorial issues and to other educational sectors? R.Balzarini LIG - ESRI France 2011

  4. 2. The Projet • To address these questions, the learning project “@atelierSIG_Geosciences” has three main objectives: • developing technical competences to master some functionalities of GIS (data management, geodatabase, analysis tools) • reinforcing methodological skills in spatial analysis (query and multi criteria evaluation) • managing a project by using a GIS in a professional environment (set up a suitability survey of a zone by using the new technologies). This system should encourage students to the construction of their portfolio of skills and stimulate their involvement and autonomy. R.Balzarini LIG - ESRI France 2011

  5. 2. The Projet Overview of the evolution of professional practices Analysis of pedagogical practices deployed in GIS university courses in Geosciences A survey of literature The learning system 2. Pedagogical resources tutoring support 3. Implementation on learning plateform 1. Scenario Evaluation 1. Method and participants 2. Observations Initial results R.Balzarini LIG - ESRI France 2011

  6. 3. The learning system • The learning approach : • corresponds to current educational practices that favor authentic learning (Simon, 1962). • is modeled on scientific inquiry (Sanchez, 2008) • uses methods and tools for multicriteria spatial analysis (Malczewski, 2004) The mission :Students must carry out a suitability study and define the potential sites for a vineyard within a given area, using ArcGIS fonctionnalities. 3.1 The scenario Designed centered on modelling of knwoledge/skills (G.Paquette,2002) R.Balzarini LIG - ESRI France 2011

  7. 3. The learning system 3.1 Pedagogical resources A learning pathway divided into6 steps : characterized by didactic aims, skills to carry out and instruction sheets to follow. Tutoring support : organized in 5 classroom teaching sessions, and an email-based online follow-up Support material : - seven worksheets : preparatory exercises (tables to complete, questionnaires …) - seven support folders : basic geomatic notions and a guide in the use of the software.

  8. 3. The learning system 3.3 The structure R.Balzarini LIG - ESRI France 2011

  9. 3. The learning system 3.4 The eLearning Environment • Two computing environments were used: • The DOKEOS learning platform, which hosts the system and allows the creation, organization, observation, and supervision of the online learning activities. • The geographic information system (the ArcGIS 9.3), which is used for data management, surface calculations and analysis, and to create the final map.

  14. 4. The evaluation • 4.1 Participants: Students from the Observatory for Sciences of the Universe of Grenoble (OSUG) masters program in Professional Earth and Environmental Sciences • specialize in geology, in hydrology and hydrological risks. Students were divided into small groups of 2 or 3 people supported by a tutor. Students are twenty-two -twenty-four years old. R.Balzarini LIG - ESRI France 2011

  15. 4. The evaluation 4.2 Method • An investigation protocol set up to identify the knowledge of students about GIS • Students production: • contractual specifications, tables to complete and questionniare, were analyzed in order to identify their drawbacks in terms of theoretical knowledge. • Individual interviews: were analyzed to pinpoint the evolution of the students’ perceptions on methodological and technical knowledge. R.Balzarini LIG - ESRI France 2011

  16. 5. First results • Students productions show gaps in • - data format • - feature data and raster data set representation • choice of the analysis method • how to manage a project, from the analytical approaches to the technical solutions. • The interviews analysis shed light on the capacity to improve mainly two comptences: • 1. be able to structure a territorial diagnosis • 2. be able to target the use of spatial analysis tools offered by the GIS.

  18. CONCLUSIONS and OUTLOOK This first work is a preliminary phase of exploration, which continue in a research project, with a CIFRE-ANRT agreement between: Learning GIS in Applied Geosciences “Evaluation of the integration of methods and techniques for mapping land suitability.” R.Balzarini LIG - ESRI France 2011

  19. EVOLUTION and OUTLOOK Research questions Students in geosciences lack skills in mapping a GIS-based multicriteria evaluation for land-use suitability analysis. 1. What lack of skills? 2. How to cararcterize them? (problem, criteria, indicators) R.Balzarini LIG - ESRI France 2011

  20. EVOLUTION and OUTLOOK Hypothesis H0. Students lack skills in performing systemic analysis (with spatial multicriteria evaluation). H1.Students lack synthesis skills needed to make a land-suitability map (Bloom,Synthesis: Builds a structure or pattern from diverse elements. Put parts together to form a whole, with emphasis on creating a new meaning or structure). H2.Students lack visual analysis skills needed to interpret a land suitability map. (Armstrong et Al., map-centered-exploratory analysis). R.Balzarini LIG - ESRI France 2011 22

  21. EVOLUTION and OUTLOOK Expected results : • A model of student reasonning on MCSA • Recommandation to improve student reasonning • Scaffolding scenario and support Thank you for your attention ! R.Balzarini LIG - ESRI France 2011
