Are lab experiments valid?
Are lab experiments valid? – Results of laboratory experiments tend to be reliable, as the conditions created (and thus results produced) can be replicated. – Data collected may lack ecological validity, as the artificial nature of laboratory experiments can cast doubt over whether the results reflect the nature of real life scenarios. What are the […]
Why do some students struggle with learning and completing tasks?
Why do some students struggle with learning and completing tasks? Students struggle in individual activities because they did not gain deep understanding during previous group work.
