Practice of Handheld Technology in the Teaching of Chemical Reaction Rate
The handheld technology presents the dynamic change process of the experiment in the form of graphics and images,which embodies the full integration of modern technology and chemistry.Using handheld technology to carry out experimental research on factors affecting chemi-cal reaction rate,it can explain the dynamic change process of the influence of different concentrations,pressures,temperatures and catalysts on chemical reaction rate from the perspective of graphics and images,so as to promote students'understanding and cognition of factors affecting chemical reaction rate.
