Research question

Sample Solution

Absolutely. Here's my research question and a discussion of potential biases:

Research Question:

"To what extent does the implementation of personalized learning technologies in secondary mathematics classrooms correlate with improved student performance and engagement, and how do these effects vary across different socioeconomic backgrounds?"

Identified Biases:

1. Selection Bias:
   • Schools and teachers who volunteer to participate in studies involving personalized learning technologies may already be more technologically inclined or have a pre-existing interest in improving student outcomes. This could skew the results, as these schools might not be representative of the broader population.
   • Students who are comfortable with technology or have access to resources at home may benefit more from personalized learning, creating a biased sample.
2. Confirmation Bias:
   • Researchers who are proponents of personalized learning might unconsciously interpret data in a way that supports their hypothesis, overlooking negative or neutral findings.
3. Socioeconomic Bias:
   • The study specifically addresses socioeconomic backgrounds, but it's crucial to acknowledge that access to technology, internet connectivity, and parental support can vary significantly across these backgrounds. This can create confounding variables that are difficult to isolate.
   • Those students from lower socio economic backgrounds may have less access to technology outside of the classroom, and therefore be at a disadvantage when using personalized learning technologies.

1. Measurement Bias:
   • "Student engagement" is a subjective measure. How it is measured may produce bias. Surveys, observation, and test scores, all have their own biases.
   • "Student performance" can be measured in many ways. Standardized tests, teacher evaluations, and student portfolios all measure different aspects of student performance, and each can produce a bias.
2. Hawthorne Effect:
   • Students and teachers may alter their behavior simply because they know they are being observed, leading to artificially inflated results.

Response to Doctoral Degree Question:

"As I've delved deeper into research throughout this course, my interest in pursuing a doctoral degree has definitely grown. The ability to conduct rigorous, in-depth investigations into educational practices, particularly those involving technology and equity, is incredibly appealing. I recognize the challenges inherent in research, including the need to mitigate biases and ensure validity. However, I'm also excited by the potential to contribute meaningfully to the field and inform evidence-based practices. So, yes, I would now seriously consider pursuing a doctoral degree to continue my research."
