This paper also discusses a few research questions that theywant to solve. Question one. What effect does encouraging the use of Twitterfor education have on student engagement? To examine the effect of Twitter onstudent activity, the researchers used a mixed effects ANOVA model, withsections nested within treatment groups. The dependent variable was the differencescore between the post-test administration of the engagement instrument and thepre-test administration.
Question two. What effect does encouraging the use of Twitteron education have on grades?And there are several results that they have came up with,the analyses of difference scores show that there was a greater increase inengagement scores for the experimental group than the control group. From thisthey had made a conclusion that using social media such as Twitter had apositive effect on student activity as measured by their instrument. Becausethey conducted analyses on difference scores, they took into accountpre-existing differences in engagement level.
Their analyses show that encouraging the use of Twitter foreducationally relevant purposes has a positive effect on grades. They alsofound out that no pre-existing differences between the groups on high schoolGPA, indicating that the groups were equivalent in terms of academic ability. Thisstudy provides the first piece of controlled experimental evidence that usingTwitter in educationally relevant ways can increase student activity andimprove grades hence, social media can be used as an educational tool to helpstudents reach desired outcomes.
There are several limitations to this research.The first and most important limitation is that the study was conducted on anarrow sample of the overall student population at an institution that is notnecessarily representative of all institutions in the United States, let aloneinternationally. Another limitation is the engagement instrument.
It isimportant to note that we measured the construct of engagement throughself-report and not actual student engagement
