  1. Methodology and results to analyse conceptions on nature utilization and preservation among teachers from 16 countries François Munoz, Franz Bogner, Pierre Clément and Graça S. Carvalho Environmental Psychology Conference 2007 – Bayreuth, Germany September 9-12 2007

  2. The Biohead-Citizen project • Scientific issues in biology, health and environment Environmental Education Health Education Human Reproduction and Sex Education Genetic and biological determinism Evolution

  3. The Biohead-Citizen project • Conceptions of (future) teachers The main goal is to clarify their structure and analyse them as social representations Potential impact on what is taught at school • Personal information A specific part of the questionnaire + disseminated political questions • Throughout 16 countries

  4. Environmental Education • Teachers’ environmental attitudes “Collection of beliefs, affect and behavioural intentions a person holds regarding environmentally related activities or issues” (Schultz et al, 2004) • Cognitive structure Two-dimensional ecocentric-anthropocentric paradigm (Thompson and Barton, 1994; Bogner et al, 2000) Goal: Better prediction of behaviours

  5. Question 1 A4 Utilization (anthropocentric) Question 2 A8 … Preservation (ecolocentric) The Biohead-Citizen questionnaire • Structure of questions = issues of interest Environmental attitudes

  6. P1 - Portugal InB – In service biology secondary P2 - France PreP – Pre service secondary P3 - Germany … … The Biohead-Citizen questionnaire • Structure of individuals = sampling groups Country Teaching groups

  7. 1 2 3 4 Describing the data • Answers to the questions A numeric coding is used A16: Our planet has unlimited natural resources I don’t agree I agree Likert scale

  8. Describing the data • Answers to the questions A16: Our planet has unlimited natural resources

  9. Multivariate statistical analysis • Purposes Global dependence between questions/issues according to theoretical expectations Structure of questions • Different attitudes across sampling groups: • regarding all issues. • regarding particular issues Structure of individuals

  10. Multivariate statistical analysis Basic principle New variables Questionnaire Capturing synthetic components

  11. Multivariate statistical analysis • Properties of the new components • Components are linear combinations of questions • Independence : no correlation • between the components • Variance partition: ordering • by decreasing variance V1 = 0.5A1 - 0.3A2 + 0.6A3 + 0.8A4

  12. Multivariate statistical analysis • Main methods available • Principal Component Analysis (PCA): euclidean • distance between individuals. Only with quantitative data • Correspondance Analysis (CA): chi-square • distance, well suited to categorical data.

  13. Multivariate statistical analysis • Featuring the variation in attitudes Variance according to the components V1 V2

  14. 1 2 3 4 Environmental attitudes Structure of attitudes 15 questions– Principal Component Analysis Preservation Characterizing the attitudes Arrow for Likert scale V1 Utilization V2

  15. Environmental attitudes • What most differentiates the attitudes in socio-cultural groups Between-group analysis • Look for combinations of questions that most • differentiate the groups • One can relate the new components to the • structure of the basic PCA analysis

  16. U U U U U U U Structure of individuals • What most differentiates the groups 16 country groups

  17. Structure of individuals • Is the differentiation significant ? Country groups Randomization test Actual differentiation p-value < 0.001

  18. Structure of individuals • What most differentiates the groups Between-group analysis • This kind of analysis may be applied either to • separate issues or to the whole questionnaire. • One may investigate differentiation between • countries, religions, teaching groups… according • to specific hypotheses. • Analysis on groups inside any country.

  19. Structure of individuals • Controlling for the effect of country Orthogonal analysis • Look for attitudes that are independent from • the teachers’ nationality • Point out if a common structure emerges • throughout the countries

  20. Preservation Utilization Structure of individuals No difference between countries • Orthogonal analysis controlling for country

  21. Looking for causes • Orthogonal analysis Controlling the effect of one factor • Analysing attitudes independently from the effect • of a given factor Independent test of another factor • We separate out the effect of both factors

  22. Looking for causes • Religion and country are not independent • Some factors can be counfounding

  23. Looking for causes No difference between religion groups 1 - Orthogonal analysis controlling for religion

  24. Looking for causes Differences between countries independent from religion 2 - Independent effect of country

  25. Analysis of the cognitive structure • Non-parametric statistical framework Investigating the effect of two factors A and B 1- Global PCA: effect of both A and B 2- Orthogonal analysis controlling for A: independent effect of B 3- Orthogonal analysis controlling for B: independent effect of A 4- Orthogonal analysis controlling for A and B: effect of the interaction between A and B

  26. Opening up the discussion • Multivariate analysis helps clarifying the structure of environmental attitudes What are the attitudes according to which individuals are most contrasting? • Specific approaches allow testing hypotheses What most differentiate groups of individuals?  Between-group analysis Can we distinguish the effects of related factors?  Orthogonal analysis Randomization tests
