Argument Map: Loewi's Argument That Neuro-Transmission Works With Chemical Signals Instead Of Eletrical (Short Version), Michael Hoffmann
Argument Map: Loewi's Argument That Neuro-Transmission Works With Chemical Signals Instead Of Eletrical (Short Version), Michael Hoffmann
Michael H.G. Hoffmann
This argument shows how the hypothesis that muscles are probably stimulated exclusively by chemical signals and not by electrical ones can be justified by Loewi's experimentum crucis.
Hypothesis Generation And Testing: A Template For Biomedical Research, Michael Hoffmann
Hypothesis Generation And Testing: A Template For Biomedical Research, Michael Hoffmann
Michael H.G. Hoffmann
This argument map provides a template for the testing of hypotheses in biomedical research. It can be used in science education to direct students' attention to all components that need to be clarified to justify a scientific hypothesis in a specific experimental setting, including the justification of appropriate sample sizes in experiments, determination of background theories, description of experimental design, data collection methods, significance level, etc. To use this template, go to http://agora.gatech.edu/, search for argument map 3363, and copy the map.
Argument Map: Devoloping Scientific Hypotheses And Experimental Designs In Form Of An Argumentation. Loewi's Crucial Experiment On Chemical Neurotransmission, Michael Hoffmann
Argument Map: Devoloping Scientific Hypotheses And Experimental Designs In Form Of An Argumentation. Loewi's Crucial Experiment On Chemical Neurotransmission, Michael Hoffmann
Michael H.G. Hoffmann
This argument map presents Paul Loewi’s crucial experiment in which he showed that neural transmissions of signals are chemical in nature, not electrical, in form of an argumentation. The map can be used in science education to show how the formulation of hypotheses should be related to a corresponding determination of experimental designs.
