The OLabs is based on the idea that lab experiments can be taught using the Internet, more efficiently and less expensively. The labs can also be made available to students with no access to physical labs or where equipment is not available owing to being scarce or costly. This helps them compete with students in better equipped schools and bridges the digital divide and geographical distances. The experiments can be accessed anytime and anywhere, overcoming the constraints on time felt when having access to the physical lab for only a short period of time.
- The features include :
- Content aligned to NCERT/CBSE and State Board Syllabus.
- Physics, Chemistry, Biology Labs from Class 9 to Class 12. English and Maths lessons for Class 9 and 10.
- Interactive simulations, animations and lab videos.
- The concepts and understanding of the experiment.
- The ability to perform, record and learn experiments - anywhere, anytime, and individualised practice in all areas of experimentation.
The 'learning-enabled assessment' through OLabs facilitates in the assessment of; the procedural and manipulative skills of the experiment, the concepts and understanding of the experiment and a student's reporting and interpreting skills.
The development of OLabs includes the study and use of mathematical techniques to demonstrate the various complex functions in diverse areas of science. The labs make use of cutting edge simulation technology to create real world lab environments. Thorough study and research is done by research personnel for better understanding of the experimental procedures. Real lab scenarios are captured through live demonstration of the experiment so as to assimilate information on the procedures and lab equipment. Visualisation and development of the graphical symbols are done based on realistic situations and compared with the respective real equipment. Simulations are made interactive using various authoring tools, thus recreating and simulating a real lab environment.
The OLabs are hosted at www.olabs.edu.in. Access to OLabs is free for Schools upon registration.
