Most teaching content can be provided online, readily via the Internet and science and engineering classes, however, are more difficult as they generally require parts of laboratory and field work as well as hands-on experience to receive the complete course credit for learners. In today’s distance schooling, laboratory and field work to improve hands-on or first-person experience remains a significant challenge. Laboratory parts currently involve learners to travel to a university laboratory or obtain laboratory kits sent by the university in distance education organizations. Due to high cost and time constraints, these alternatives have their limitations. Laboratory performance and assessment can be jeopardized if there is no monitoring or monitoring record.
Laboratory alternatives for online education studies and development are divided into three interrelated classifications: virtual, actual and remote. The requirement for laboratory job is an apparent task for learners taking internet science and engineering classes. Other alternatives include: demonstration laboratories; simulation laboratories; virtual reality laboratories; virtual reality laboratories (VR); and the sending of laboratory kits to learners to do laboratories at home. Computer-based laboratory simulations, remote access laboratory, and allowing remote activity were included in teaching internet science: practical guidelines for efficient training and laboratory.
Among the five kinds of online education laboratory alternatives mentioned above, demonstration laboratories generally do not include the participation of learners. Demonstration laboratories record activities in a physical laboratory to demonstrate how a laboratory job is accomplished, as well as all the details of the results of the laboratory, and send the recording to watching learners, such as those at chemistry lab., where a video can be found showing how a volcano erupts. Not much research and development is engaged in this category of laboratory delivery other than physical laboratory operation and quality video recording. Demonstration laboratories have the benefit of being easily delivered to learners. Students can readily use a internet connection to access demo videos or software. Demonstration laboratories may be followed by interactive communication for issues or clarifications between learners and teachers, while no teacher is included in the asynchronized teaching model. Demonstration laboratories are less efficient in those instances. Simulation laboratories involve the participation of students, but not direct handling of laboratory equipment and materials. Some examples of this sort of simulation laboratories offers a simulator for manipulating bricks in physics to learn balancing acts.Virtual laboratories enable students to access virtual laboratories produced by computers via a computer interface. It is particularly helpful for learners, such as students in distance education, who lack access to a true laboratory.
While doing laboratory experiments at home with a laboratory kit may provide learners with the chance to gain real-world experience working with laboratory instruments, equipment, and practice true laboratory procedures, the kinds and scales of laboratories that can be accomplished at home are restricted owing to their complexity or safety issues. It is evident for many reasons that not all laboratories can be accomplished at home. Remote access to laboratories, i.e. remote labs, is another approach to offering students with actual laboratory experience. Developing robotics, computing systems, and the Internet offers opportunities for internet learners to introduce more efficient and innovative methodologies.
