  1. 1. Interaction Synchronicity in Web-based Collaborative Learning Systems Ari Bader-Natal ari@grockit.com October 27, 2009
  2. 2. Interaction Synchronicity in Web-based Collaborative Learning Systems Why support synchronous interactions among learners? Ari Bader-Natal
  3. 3. Interaction Synchronicity in Web-based Collaborative Learning Systems Why support synchronous interactions among learners? Social and motivational value of having a cohort of peers: • opportunities to ask for assistance (just-in-time guidance) • opportunities for discussion (both on-task and off-task) • opportunities to earn recognition (for assisting others) Ari Bader-Natal
  4. 4. Interaction Synchronicity in Web-based Collaborative Learning Systems Why support social interactions among learners? Ari Bader-Natal
  5. 5. Interaction Synchronicity in Web-based Collaborative Learning Systems Why support social interactions among learners? Ari Bader-Natal
  6. 6. Interaction Synchronicity in Web-based Collaborative Learning Systems Why support social interactions among learners? Social and motivational value of having a cohort of peers: • opportunities to establish a reputation among peers • opportunities for receive encouragement from peers • opportunities for a study support system of peers Ari Bader-Natal
  7. 7. Interaction Synchronicity in Web-based Collaborative Learning Systems Why care about the social/motivational needs of online learners? Ari Bader-Natal
  8. 8. Interaction Synchronicity in Web-based Collaborative Learning Systems Why care about the social/motivational needs of online learners? Learning higher in blended/online learning vs. classroom learning. • Increased effectiveness may be due to the additional time-on-task. • Thought: Rather than controlling for this, view it as a new opportunity: Higher engagement  more time-on-task  higher learning rates Ari Bader-Natal
  9. 9.

  36. 36. Interaction Synchronicity in Web-based Collaborative Learning Systems Reviews: Explanation / commenting (Async) Lobby Friends Profile Feedback Messages Find a Tutor Forums Groups Users Content Ari Bader-Natal sign out Back to Reviews Previous Reviewing question 2 of 4 Next Information Question Discussion edit this question Ari Bader-Natal: tada Given the following statements, what Acceptable answers are 3/2 or 1.5. is the least possible value of b? First, multiply out the squares to get Ari Bader-Natal: ab >= 36/16. 16 a 2 + 8 ab + b 2 - (16a 2 - 8 ab + b 2) b>a> 0 > 36. All of the squares cancel out and guest 1621324565: if you you are left with 16 ab > 36. So, ab > (4 a + b ) 2 - (4 a - b ) 2 > 36 guess wrong its negative points 36/ so i left it blank 16. This fraction reduces and we have ab > 9/4. Now, since it is given Joseph Feinstein: anyone no t that a is not negative and that b is at his least equal to a , we know that the least Answer guest 1621324565: cancels to possible value for b occurs when b is what? equal to a (and not greater than a ), and Correct Answers when ab = 36 and is not greater than Ari Bader-Natal: ! 36. So, since a = b , we need to solve for b 2 = 9/4. To find that least possible 1.5, 3/2 Ari Bader-Natal: so, 8ab+8ab = value for b , then, we can take the 16ab. square root of 9/4 , which is 3/2 Ari Bader-Natal: then, b^2 >= (remember, it is given that b is not Responses 36/16. negative, so we are looking for the positive square root). The answer can 1.50 Ari Bader-Natal: so, at the least, b=6/4 = 3/2 = 1.5 be grid as 3/2 or 1.5. 4 Jazzmond S. Jones: not a clue Ari Bader-Natal
  37. 37. Comments About This Question Luke Drakas: wow my Interaction Synchronicity in Web-based Collaborative Learning Systems multiplication skills arehorrible... Khuong Le Delete this comment Sunday at 10:07PM guest 1621324565: guess not Reviews: Explanation / commenting (Async) thank! your explanation is really helpful Ari Bader-Natal: (4a+b)^2 - Tiffany Riley Delete this comment Saturday at 02:52PM (4a-b)^2 mostly cancels out. thanks- every step is explaned and the reason behind the procedures. Luke Drakas: ohhhh k thanks i understand now EL MALIKI Sofia (FBS) Delete this comment Friday at 12:07PM Luke Drakas: i got that far Thanks y'all!!! Very helpeful!!! (16ab ) guest 1621324565: i simplified Jazzmond S. Jones Delete this comment Saturday at 04:59PM to ab is greater than or equal to 4 still confused don't know where the 8ab came from Ari Bader-Natal: divide both sides by 16, and you get... Anantharam Peesapati Delete this comment Monday at 09:08AM Ari Bader-Natal: here's an really good explanation. thanks!! ;) explanation: kumar manish Delete this comment Thursday at 12:05PM Ari Bader-Natal: since b is, at the least, equal to a, let's good explanation! assume that it is A. Joseph Feinstein: so it is four? odarri Lewis Delete this comment Friday at 09:27PM thank you! Ari Bader-Natal: square root of both sides, and you get b>=6/4 Sherzod Kutfiddinov Delete this comment Tuesday at 02:15AM Luke Drakas: .how did u get nice 1.5? Ari Bader-Natal: you're left with Sara Gennaro Delete this comment Tuesday at 03:02PM ( 4ab*2) - (-4ab*2) i had no idea how to do the problem beforehand, and the explanation was very Ari Bader-Natal: hope that thorough and helped a lot!! helps! guest 1621324565: smart man Sidak Singh Dhillon Delete this comment Saturday at 09:48AM that's a really good question.
