What is Learning Sciences?

According to the International Society of Learning Sciences (ISLS),

“Researchers in the interdisciplinary field of learning sciences, born during the 1990’s, study learning as it happens in real-world situations and how to better facilitate learning in designed environments – in school, online, in the workplace, at home, and in informal environments. Learning sciences research may be guided by constructivist, social-constructivist, socio-cognitive, and socio-cultural theories of learning.”

Methods of Research: Qualitative, Quantitative within design-based research

“Although controlled experimental studies and rigorous qualitative research have long been employed in learning science, LS researchers often use design-based research methods. Interventions are conceptualized and then implemented in natural settings in order to test the ecological validity of dominant theory and to develop new theories and frameworks for conceptualizing learning, instruction, design processes, and educational reform. LS research strives to generate principles of practice beyond the particular features of an educational innovation in order to solve real educational problems, giving LS its interventionist character.”

F-ration and regression

  • F-ratio = The most important part of the table is the F-ratio, which is calculated using equation, and the associated significance value of that F-ratio. For these data, F is 99.59, which is significant at p < .001 (because the value in the column labelled is less than .001). This result tells us that there is less than a 0.1% chance that an F-ratio this large would happen if the null hypothesis were true. Therefore, we can conclude that our regression model results in significantly better prediction of record sales than if we used the mean value of record sales. In short, the regression model overall predicts record sales significantly well.
  • Regression: make a prediction about the future when the outcome is a continuous variable
  • Logistic regression: when the outcome is a categorical outcome(fireman, doctor, or pimp)

A small standard error tells us that most pairs of samples from a population will have very similar means (i.e. the difference between sample means should normally be very small). A large standard error tells us that sample means can deviate quite a lot from the population mean and so differences between pairs of samples can be quite large by chance alone.

Coffee roasters in Athens and C’ville

I love coffee. Unfortunately (or maybe fortunate to my body), I am quite sensitive to caffeine and cannot drink more than one cup of coffee, about 12 oz.

Though I love the the aromas and the nutty, chocolaty, caramelly, earthy flavors in it. I love to drink a manual pour- over coffee, sometimes espresso drinks such as espresso machiatto or americano. And milk added espresso such as cappuccino and latte are in my list of favorites coffee drinks.

One of the reasons I enjoyed my life in Athens was because Athens has great coffee roasters and places. Jittery Joe’s coffee, 1000 faces coffees, and two story coffee are my favorites. Personally, I prefer 1000 faces coffees as their coffee has more subtle aromas and tastes than Jittery Joes. Sometime I enjoyed Jittery Joe’s coffee but only when I needed a very strong cup of coffee. Anyway, I would say that thanks to that two coffee roasters, I could enjoy my doctoral student years.

It’s been two months since I’ve moved in C’ville. And I’ve realized C’ville has great coffee roasters as well. I’ve tried Mili Joe’s, Shennadoah Joe’s, and greenberry’s. And so far, my favorite is Shennadoah Joe’s at Preston Avenue. A half of their store is a roasting place. They are roasting and packing a variety of beans there. Of course the store is full of coffee aromas all the time, and I love to seat there and sip a cup of fresh pour-over coffee.

Having a place, that makes me have some good relax and refresh, is always making my life more enjoyable.

exhusting day

오늘은 아침부터 늦은 저녁까지 하루종일 지친하루였다. 푹 잔거 같긴 한데, 개운하진 않았고..무슨 꿈을 (분명 개꿈 같은..) 꾸다가 이게 무슨소리지? 하며 깼는데 그게 알람소리였고…꾸욱 누르고 다시 잤다가 눈을 떴는데, 알람을 끄고 한 30분을 너무 꿀잠을 자서 내가 왜 침대에 누워있지..오늘 할일이 뭐지?? 하며 헐레벌떡 일어나서…별로 달갑지 않은 콜레버레이터의 이메일을 보고 기분이 나빠지고, 그걸 열어보고서는 더 기분이 나빠지고….기분이 덜 나빠질까 싶어서 얼른 아침먹고 잠깐 그 일을 들여다봤다가..괜히 필라테스나 5분 늦고…

오늘이 4번째 그룹 필라테스 수업이었는데, 이제껏 중에 근육 피로도가 웬지 좀 높아서…동작할때마다 기분좋음보다는 살짝 힘들다는 생각이 좀 들었다. 그러다보니 보통은 끝나고 항상 아침을 일찍 잘 시작했다는 뿌듯함..아침에 필라테스로 내 몸의 비뚤어진 부분을 교정해서 자세도 몸도 가벼워진 그런 기분이 들었는데..오늘은 노노…대신에 무슨 생각을 했더라? ….’아..끝났다..바로 가서 아까 하던 일 마저 보고, 오늘 회의가 두 개니깐 준비해야겠다….휴우…’

오전 8시 15-9시 15분 필라테스, 커피샵에서  pour over coffee 라지로 시켜서 마시며 아침부터 내 심기를 건드렸던 그 문서를 들여다보다가, 11시부터 1시까지 프로젝트 1차 미팅..2시-5시 미팅 전에 얼른 학교안에 유일하게 문열고 있는 베이글 가게에서 베이글 하나 먹고.. 집에왔다…저녁먹고 작은 하이네켄 하나 마시고…흠..그래도 뭔가 찝찝하고 기분 안 좋고…

오늘처럼 아침일찍 하루를 시작하고 사실 꽤나 알차게 보냈는데, 이렇게 찝찝하고 기분 안 좋음은 뭔지….할일이 너무 많아서인건지…별로 같이 일 하고 싶지 않은 컬레버레이터와의 업무 때문인건지. ..저녁 10시까지도 그렇게 기분이 다운이다가…잠시 열어본 발코니 창문….늦여름 시원한 산바람… 큰 타월 들고 나와서 돗자리에 깔고 드러누워보니…이것이 지상낙원…..풀벌레 소리…(물론 에어컨 실외기 소리도 함께 였지만…) 한 30분…누워 멍하니 있으니…힐링이 되는 기분이랄까…밖은 깜깜해서…내가 발코니에 드러누워있는지 뭐하는지 밖에서 보일리가 없고…그렇게 누워서…오늘 내가 왜 이렇게 지쳤는지 곰곰히 생각해보다보니…조금씩 기분이 좋아진것 같다..물론 아직 정확한 이유는 모르겠지만…그냥 잠깐동안 혼자 가진 이 시간이 참 좋았다..오늘 하루종일 쳐진 기분을 스을쩍 올려준 느낌…이런 발코니를 가지고 있어서 참 좋구나…

내일부터는..또 다시 기분좋은 하루를 보낼 수 있길…

Discriminant Analysis after MANOVA

Discriminant analysis is followed up after MANOVA to see the relationship between dependent variables. Which dependent variable influenced more than others /or not?

Because MANOVA results (Multivariate Tests) only showed that the group of individual variables had an effect on the dependent variables. = therapies (CBT, BT, NT) affected on the OCD clients = group performance levels affected on individual learning performance. However, the nature of this effect is unclear with Multivariate data. It tells nothing about which groups differed from which, whether the effect was on the DV1 or DV2 (= on the OCD thoughts or behaviors = on the solo test scores or group test scores).

To determine the nature of the effect, SPSS provides us with univariate tests and discriminant analysis.

workout progress week 9- 2015 summer

9주간의 운동 결과..일단 몸무게는 줄었다. 확실히 먹는 양을 조절하니까 몸무게 변화가 있긴 한 것 같다. 운동량은 첫 5주보다는 적었으나, 꾸준히 하는 정도로만 했는데도 준 것 보니..운동량이 좀 준 것은 필라테스의 영향도 있는 것 같다. 일주일에 두 번 필라테스를 하는날은 노곤해서 그냥 유산소도 안 하고 넘어갔었다. 앞으로는 필라테스 한 날도 되도록이면 30 분 유산소는 해야겠다는 생각이 들긴 하지만..

몸무게나 좀 줄은 것을 보니, 운동을 덜 하려는 마음이 스물스물 올라온다. 하지만 다잡아야하는게..이번 운동은 올 해 연말까지 이어지는 운동계획이라는거.. 10주에서 13주 동안 운동계획은 이전 운동보다 좀 더 조여줘야겠다. 몸무게가 줄은 것을 보니 일단 근력도 조금 붙은 것 같으니..지속적으로 하면 또 3주 뒤에는 효과가 있을거라 믿는다.

1주에 필라테스 1.5회, 유산소 매일 30분씩 (=210분, 21 mile), Weight Training 2.5회
