Tiemann Chemistry      Education Lab


PhD Defense

September 2019

T-CEL member Ines Sonnenschein, née Gerling, has successfully defended her PhD in the project "Fostering Scientific Inquiry - Problem based labwork activities for bachelor studies in analytical chemistry".  She was able to show impressively how different scientific methods affect the cognitive process and was also able to demonstrate hybrid forms by means of a very valid coding manual. She also succeeded in demonstrating interactions between the solution behaviour of a task to be processed experimentally and its design by means of various prompting measures.


Congratulation - well done!



September 2019

At the joint meeting of the GDCP and the FDDB in September, the working group presented current research projects and new project ideas. In posters and lectures, questions ranging from mental modeling to the difficulty of representing molecules were successfully discussed.



July 2019

Dr. Mark Winterbotton (University of Cambridge) and Elizabeth McGregor Jacobites (WonderWorld Sciences) visited T-CEL and participated in a two-day workshop "Perspectives on problem solving".

They presented the "Tinkering" approach with a practical example and then discussed the conceptual differences and similarities to traditional problem solving approaches with the group.


Prof. Dr. Rüdiger Tiemann

Head of the Chemistry Education Lab

The research program of the Tiemann Chemistry Education Lab has a strong commitment to knowledge acquisition by problem solving. In quantitative studies with technology based tools the focus is on describing, assessing and supporting  the fundamental mechanism behind this process.  



"We only think when we are confronted with problems."

(John Dewey)



Combined with the use of experiments and the use of mental models to understand  core concepts of Chemistry, the research program empowers the Tiemann Chemistry Education Lab  theory driven and empirically founded to investigate students' thinking individually or in classrooms. Alumni group members serve as Professors, for Science Outreach Organizations or as Chemistry Teachers.



The Chemistry Education Lab at Humboldt-University serves more than 100 students at K-12 (Sekundarstufe) and primary level (Primarstufe) each year through a diverse portfolio of theoretical background knowledge and first practical learning experiences. 


The professional learning program is designed to improve the skills and competencies in creating innovative learning environments and to learn first teaching experiences. Up to 10 students per year have the chance to finish their studies in T-CEL with a thesis (M.Ed.).
