Name and describe the theory presented in the introduction section of the article.
Cognitive Load Theory: Is a hypothesis that attempts to understand the human thought process.
Which of the following research methods was used in study 1 and study 2?
Study 1: Survey; Study 2: Experiment.
In your own words, state the hypothesis for study 1 and study 2.
There is an increase in cognitive load if unnecessary destruction and anxieties are imposed on a learner.
Describe the samples for study 1 and study 2, including number of participants and at least 2 other characteristics of each sample.
Delegate your assignment to our experts and they will do the rest.
In study 1, samples were surveys from 693 students. Their average age was 20.5 and ninety-nine had cell-phones. In study 2, the samples were 82 students. Of the 82, 21 were men while 19 were women. The samples had phones during the study and got no incentive on the participation.
Identify the independent variable(s) used in study 1 and study 2.
Provide an operational definition of the IV
Independent variables are aspects of a study that a researcher can manipulate for example substance exposure. In study 1, the metric for performance used in the study represent independent variables as the researchers were able to control its application in the study. In study 2, the independent variable was the lessons offered o the samples.
How many groups or conditions were there?
In study 1, there were two groups; those who had phones and those without phones. The conditions in study 2 were one group was to text while the other group was non-texting. The participants were all to watch a presentation.
Provide an operational definition of the dependent variable measured in study 1 and study 2.
In study 1, measurement was done by the use of a Tukey post hoc. The test measures the frequency of users on the use of their cell-phones while in class. In Study 2, measurement was done by noting the number of times a text message was received and the PowerPoint presentation started. Time was noted on the amount of time a participant reading or texting during the texting wait.
Summarize the results of study 1 and study 2 in your own words. Don’t get caught up in the statistics. Just describe the main findings.
The primary findings reveal that classroom cell-phones have a significant impact on students learning and increase the cognitive load during classwork.
a)
Are the samples appropriate for testing the hypothesis stated in the study? Why or why not?
The samples are appropriate but there is the challenge of some students failing to understand the study’s baseline minimum while some may not account for their performance engagement especially those linked with multiple choice queries.
Is the research method and design appropriate for testing the stated hypothesis? Why or why not?
Yes, the research method is appropriate as it uses/applies a live classroom scenario in which the participants on a normal day engage in learning. It is a replica of their day to day learning environment.
Describe what you see as one strength of the study using terms from Module 2.
Population validity: The sample used could easily be deduced as a whole population.
Describe what you see as one weakness of the study using terms from module 2.
There were ethical and practical limitation in the entire study for example, reduced chances of participants understanding the set baseline minimum.
