  1. 1. Visual thinking, visual speech : a semiotic perspective on meaning-making in molecular life science : how visualizations, metaphors and help-words contribute to the formation of knowledge about proteins among upper secondary and tertiary level students

    Författare :Carl-Johan Rundgren; Lena A E Tibell; Richard Hirsch; Ute Harms; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Molecular life science; visualizations; metaphors; help-words; Subject didactics; Ämnesdidaktik;

    Sammanfattning : Molecular life science has become one of the fastest-growing fields of scientific and technical innovation. An important issue for tomorrow’s education is to meet the challenge posed by various facets of molecular life science. LÄS MER

  3. 2. Evolving germs – Antibiotic resistance and natural selection in education and public communication

    Författare :Gustav Bohlin; Lena A. E. Tibell; Gunnar Höst; Jörg Zabel; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; natural selection; antibiotic resistance; visualizations; content analysis; threshold concepts; scientific literacy; media analysis;

    Sammanfattning : Bacterial resistance to antibiotics threatens modern healthcare on a global scale. Several actors in society, including the general public, must become more involved if this development is to be countered. The conveyance of relevant information provided through education and media reports is therefore of high concern. LÄS MER

  4. 3. Topsar och cellmembran : Kroppens näringsupptag i undervisning och elevtexter på mellanstadiet

    Författare :Alma Jahic Pettersson; Carl-Johan A. Rundgren; Lena Tibell; Ragnhild Löfgren; Nicklas Gericke; Linköpings universitet; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Social semiotic; Metaphors; Everyday expressions; Systemic functional grammar; Organizational levels; Biology; Chemistry; Multimodality; Socialsemiotik; Metaforer; Vardagsuttryck; Systemisk funktionell grammatik; Organisationsnivåer; Biologi; Kemi; Multimodalitet;

    Sammanfattning : I avhandlingen studeras mellanstadieelevers meningsskapande kring näringsupptag. Avhandlingens artiklar baseras på två datainsamlingar. I den första studeras skriftliga svar på ett nationellt prov i biologi. I den andra studeras klassrumsundervisning i två skolor med en animation om näringsupptag som kontext. LÄS MER

  5. 4. Touching the Essence of Life : Haptic Virtual Proteins for Learning

    Författare :Petter Bivall; Anders Ynnerman; Lena A. E. Tibell; Matthew D. Cooper; Miriam Reiner; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Haptics; Educational Research; Biomolecular Education; Life Science; JND; Just Noticeable Difference; Protein-ligand Docking; Haptic docking; Visualization; Haptic Transfer Functions; Volume Data Haptics; History Dependent Transfer Function; Log file analysis; Molecular Recognition; Force Feedback; Virtual Reality; Other information technology; Övrig informationsteknik;

    Sammanfattning : This dissertation presents research in the development and use of a multi-modal visual and haptic virtual model in higher education. The model, named Chemical Force Feedback (CFF), represents molecular recognition through the example of protein-ligand docking, and enables students to simultaneously see and feel representations of the protein and ligand molecules and their force interactions.
