Design and Practice of Basic Physical Experiment Teaching Based on Combination of Virtual and Real In the process of design of physical experiment teaching, the virtual instrument LabVIEW has been introduced into the teaching course of the physical laboratory to construct a basic physical experiment platform combining virtual and real. In the teaching practice, the advantages and characteristics of the physical experiment and the virtual experiment are fully combined, and a hierarchical teaching system is adopted to design the experimental teaching content from shallow to deep, and a physical experiment platform combining virtual and real is developed. Only in this way can the studentsxe2x80x99 experimental innovation ability be effectively improved and can the innovation education be smoothly carried out.

Blended Learning Approach using Virtual Laboratory Applications in Engineering Chemistry Traditional classroom teaching practices often lacks the active engagement of students in the class. Performing experiment in the laboratory is one of the most effective methods for getting deep knowledge in chemistry. But sometimes listening theory lectures and performing related experiments in the laboratory does not helps the students to understand the concepts clearly, as this lacks repeatability and visualization of concepts. Induction of virtual laboratory in combination with theory lectures and physical laboratory could solve this problem. Virtual laboratory have multifaceted advantages such as repetitive performance, easy to handle simulations and remote triggered experimentations. Such remote triggered laboratories found to enhance studentsu0027 academic performance as it enables them to perform anytimeanywhere. In this paper, we report our observations regarding the use of virtual laboratory experiments in chemistry subject and their role in enhancing First Year B. Tech. engineering studentsu0027 performance when induced as a blended classroom. UVVisible spectrophotometry experiment was performed to verify the usefulness of virtual laboratory from studentu0027s knowledge perspective. The effect of a blended learning approach was carefully studied and evaluated in comparison with traditional classroom teaching and virtual laboratory. Our study reveals the enhancement of studentu0027s performance in a blended learning environment compared to just physical performance in the laboratory and performing individually with the virtual laboratory.
