Day 6

Got a good chunk of the paper written today, with some final analysis and discussion left to do. Tried using jMetrik, an open-source psychometric software.

It was a huge help - the first user-friendly Rasch Measurement software and it runs on macOS. Meanwhile, I finally decided to use Item Response Theory (IRT) because it is suitable for models where the indicators are discrete variables and the latent variables are continuous. In its plain form, factors such as the "difficulty" of the options and the discrimination of each items are estimated as parameters.

9:30 AM- 3:50 PM (Yes I didn't go to lunch)
6 hours 20 minutes

Weekly Reflection 2

For me, who had not been exposed to statistics prior to this school year, AP Statistics, even if it only consisted of an introduction to statistics, was an enormous help. The way it reshaped my understanding of other theories, as well as real-life practice, is unparalleled.  As I decided to carry out this research, I read a great deal of literature from predecessors and discovered that the task was more difficult than I anticipated. Therefore, the basic application of statistics and the initial understanding of SPSS are what I consider to be the biggest gains, if only in terms of knowledge rather than competence. Likewise, the application of observation, research, and theory, the ability to locate information from vast literature, and the ability to focus on details are also skills I am now beginning to realize. In my capacity as a member of the community, I am constantly searching for something I can contribute. From the exploration, design, and planning stages to the implementati...

Week 1 Reflection

     I always shudder to think that a week has passed and the work done seems far from the complexity and perfection I envisioned at the time. Of course, I had to remind myself that I am only a high school student, and that I need not be overly ambitious. Some of the content--such as the methods and theories of statistics--was far beyond the depth and basic level required in high school, while others needed extensive literature reading and search skills. I eventually decided to cut out some of the reliability and validity tests, because even if I could do the "analysis" in a step-by-step manner as described in the book or guide, I would have learned no knowledge or understanding of the principles behind it, and a complete set of such analyses would not be necessary in light of the time constraints.      It is nice to see what I have attained: a better knowledge of SPSS and other software, as well as an understanding of some of the algorithms behind them, as...

Day 9

 Completed the Exit Interview! Discussed the overall project process with numerous faculty members and shared specific insights into the results and its implications in terms of both merit and interpretation from a community perspective. I am excited to be able to leave something for the school before I go and to better understand some of the current aspects of this community from this point of view. There are still some specific language refinements left that will be revised in the following days based on feedback from the faculty. 8:30-12:00 AM 3.5 hours
