A total of 50 engineering students (13 females and 37 males) participated in the survey. It often allows users to direct the process and the end product with some controllable variables of the experiment in the software. That way, classmates can directly text chat with the presenter(s) to give them private feedback without everyone else in class seeing it. The CMU system also includes a live video stream so that students can observe the experiment as if they were physically there. Wall Charts The researcher manipulates aspects of the environment in order to measure its impact on the participant's behaviour or performance - this is called the independent variable. Demand characteristics - participants aware of experiment, may change behaviour. Laboratory instruction was considered essential because it provided training in observation, supplied detailed information, and aroused pupils' interest. Virtual and online learning in the area of engineering laboratories are still new in so many ways; more research is needed if educators are to be able to fully exploit this delivery medium and its related tools in the enhancement of teaching and student learning. A major weakness of remote technologies is that they cannot easily foster the sorts of spontaneous interactions that occur in the hallways, by the office watercooler, or when people are hanging out before and after meetings. 6. However, perhaps the question we should be asking is not "What is the laboratory better than?" A laboratory experiment is an experiment conducted under highly controlled conditions (not necessarily a laboratory) where accurate measurements are possible. The High School Journal publishes manuscripts discussing the social, cultural, and political aspects of secondary education. Helpful to promote useful discussion.
