Week4: Discussion Reflection

-

     The discussions this week were all interesting in general. I'd like to note some of my thoughts here.

    First, I think I am a rather naive reader when it comes to assessing expertise. Or I do assess their expertise but do it unconsciously so that I didn't really think about the process. My classmates posted good opinions on how to distinguish expertise. I agree in general, but I think as a reader, we can feel the expertise... once we have enough information literacy. Am I saying too broadly? But that is why education for information literacy is important, isn't it?

    I also have an experience with crowdsourcing data. Last March, I posted a flyer on my social media about surveying teachers about their experience during Covid-19. I stated in the flyer that the survey is for 'in-service teachers in the U.S. elementary schools with at least three years of experience'. I got almost 300 responses over two days, with very low quality. Qualtrics saved me with its functions for detecting the location, duplicating IP addresses, time period for answering the survey, etc. With all this metadata, I could sort out only 182 valid responses. 

    Lastly, Serena and Bobby made really interesting posts about using badges in K-12 education and tagging. I am looking forward to their updates, also Serena's progress in Diigo. She mentioned a really interesting study from 2007 about tagging and I feel tagging is related to having shared legends. In my research project that I am working on as an RA, the principal investigator always emphasized having an integrated system of legends so that all the members are on the same page. I think tagging is necessary for the same reason. But for personal use, tagging will be more for an individual's self-efficacy or self-regulated learning practice. I was thinking of a research topic, to compare students' self-efficacy or level of self-regulated learning with or without tagging practice. Would tagging be really effective for improving one's learning performance?

Week4: Lingering Questions

-
 * How can a badge system be integrated into K-12 education? Are there any more examples around the world? * How can tagging improve one's learning performance? If we were to design an experiment, what would be the mediating variable or a conceptual framework? * How do Korean teachers feel about i-Scream? Do they think it's helping them or making them less professional?

Week5: Discussion Reflection

 I think this course really reminds me how it was like working as a teacher back in Korea. I'd like to mention some of my experiences with the topic in this post. But before I start, I want to note that I really like Brett and Shiyao's opinion about privacy: " When a product is free, you as the user are the product.", " In the era of Web 2.0, if I'm not paying for a product (social media), then I am the product. " I totally agree.     But what stroke me the most in this week's discussion was topic 2, the ethical concerns for educators. It was surprising to see my classmates more worried about students' privacy being invaded by educators. It's the opposite in Korea. For example, Korean parents tend to think that the teachers are not sincere enough if they are reluctant to share their phone numbers with the parents in their class. They think they should be able to contact the teacher anytime (literally anytime, even during weekends and at night

     I really enjoyed reading this week's discussion. And there are some interesting points I would love to add.      Lurking is acknowledged as a peripheral participation by some scholars. It is well elaborated in chapter 16 of this handbook of learning analytics: https://drive.google.com/file/d/1Q7hziWA3cM8SrLkXA4aJTZn1_EEwVllY/view?usp=sharing      And  there are some communities that force newcomers to lurk until they get used to the community's tacit rule. I never expected my interest in subculture can be academically helpful for me, but well, here I go. I think nobody from EME6414 would have heard about Daknunsam (닥눈삼). It means 'shut up and lurk for three months'. It was often used in Korean subculture online websites where people shared information about a game (usually Japanese). When a newbie comes in and leaves a post, asking a question in an inappropriate manner (actually it is a very appropriate and polite manner on most online websites.), all she would get
