I don’t know how many people decide to pursue PhD because they love doing research, but I am one of those people. I was raised in a learning oriented family, my father went to graduate school many years ago, and he kept doing research through his whole career life. Even in his age, he still want to pursue another degree in graduate school. My parents always educated me that, one life is short, only by making contribution to your own field can you make your life meaningful. The thought of being a researcher was deep rooted in my mind ever since.
I’ve always loved science, even when I was a kid, I always love to find the question and solve it by myself. I’ve done so many science experiments and small projects through my school life. Just as …show more content…
This research provide practitioners and researchers with an assessment on both packages in CDMs(Cognitive diagnostic models)by model retrofitting and parameters comparison. Two such R packages of interest here is CDM: Cognitive Diagnosis Modeling and GDINA: The Generalized DINA model framework. The specific cognitive diagnosis models of interest are the G-DINA model, the DINA model, the DINO model, additive CDM, Linear logistic model (LLM) and reduced reparameterized unified model (RRUM). We found out that in terms of bias and RMSE, GDINA package had lower or equal measure compared to the CDM package; in terms of PCV and PCA, both packages performed almost the …show more content…
Teachers can use this information to concentrate on those parts more and help every individual improve. This also establishes a good teacher-student understanding without spending much in-class time on assessing each individual, which eliminates the cons of having a poor teacher-to-student ratio. Thus, overall efficacy is improved with proper use of technological advancements and incorporating an emerging model having wide range of applications. Eventually, this may also result in increased levels of interest in the subject by individuals who were initially not so interested in
