  • General idea:Overall feelings were neutral. likes: anonymity, discussion, hands on dislike: cost, wanted to be lectured toMethods: the more teacher led, the more students enjoyed
  • JeremyConundrum: instructors want more engagement students say clickers increased engagement student perceptions were neutral
  • JeremyWe are going to bring you through three of the major models of ARS useThese were each implemented in the Chem class
  • FOCUS ON WHEN WE USED THIS/WHYWhen students had decent background on a concept Mainly to refine concept and move on Allowed an expert student to assist other students (though it could sometimes throw off correct students) **We remember best what we teach othersWhen there was a mix of concrete facts and abstract concepts **Allows instructor to hear thought process when consolidating a concept & jump in to lecture
  • Since students in introductory courses often try to learn through memorization, questions should be aimed beyond the remember/knowledge domain.
  • Question & a few minutes of wait timeCollect individual results (often not projected)Group discussion – defend your choice, talk through disagreementsRe-poll (most often projected)Instructor explanation majority correct: short explanation majority incorrect: lengthy explanation
  • This one will go through a full cycle – question, individual response, group discussion/response, explanation
  • The basic idea is that you will understand the concept of parabolic motion and be able to apply its impact on travel time in a given scenarioAllow a few minutes to consider the answerCollect poll results, break students into groups for 2 minutesReconvene for second poll and resultsCORRECT ANSWER: B(t)Trip = 2* square root of (2h/g) The (h) of the trajectory is less, so the (t)trip is lesser
  • Describe equation and variables and then click to show explanation.
  • CORRECT ANSWER: B(t)Trip = 2* square root of (2h/g) The (h) of the trajectory is less, so the (t)trip is lesser
  • This is another example of a concept test in the liberal arts
  • Must understand all of the terms and synthesizethem contextuallySex labeling – that’s men’s work or women’s work overt in title policeman, stewardess covert in stereotypes – nurses are women, doctors are menSupply-side is worker behaviorDemand-side is employer behaviorCORRECT ANSWER: C
  • An example of a concept test in health sciences / nursing
  • This question requires the student to not only know the terms, but to apply the appropriate methodology to a case.CORRECT ANSWER: A
  • FOCUS ON WHY WE USED THISDifferent from Peer Instrution in that more time is spent in groups and whole class discussion. This method also prefers demonstrations or short experiments over straight lecture to enhance opportunity for experiential learningWhen students had significant background & could really dig into a new experience
  • Compared to Peer Instruction it adds more layers of social constructivismNo individual responses first, rather students work together to answer & explore knowledge gaps.After responses there is a whole group discussion – teacher facilitates only
  • Students move up Bloom’s:Comprehend concepts / refine miscomprehensionConnect parts of a whole (many forces at work, e.g.)Analyze a problem using related concepts – explore, discuss, etc.Solve a problem using related concepts – final step
  • This one will go through a full cycle – question, group discussion/response, whole room discussion, demo/explanation
  • CORRECT ANSWER: BBreak into small groups to discussPoll after discussion and show results
  • After discussing you would provide a demonstration or lecture to clarify any misconceptions or misapplications of a concept
  • You can see, especially in the slow motion, that his motion is linear (not curved) and continues in a straight line (that is, not tangential) from the point of departure

    12. 12. Classroom Responses:Final Exam ResultsStudents achieved an 88.4% correct response ratefor final exam questions with a similar in-classversion.Students achieved a 71.4% correct response ratefor final exam questions that were new or were nottaught with clickers.Questions remain: How much is because it wasfamiliar? How much is because it was “easier”?How much is because it was “recent”?

    34. 34. Whole Class DiscussionDiscuss reasoningQuestions to help rejecting incorrect options◦ What would the motion be if the child kept holding therock?◦ What would have to happen to cause the rock’s motion tobecome perpendicular to its current path?◦ What might the path of the rock look like to the child?

    38. 38. Branching LectureACID-BASE ANDDONOR-ACCEPTORCHEMISTRY
    39. 39. Which of the following is anexample of an Arrhenius acid?1) HCl in acetic acid2) HCl in water3) both 1 & 24) neither 1 nor 2
    40. 40. History:Antoione Lavoisier (~1776): oxide of N, P, SJustis von Liebig (1838): compound with Hreplaceable by metalSvante Arrhenius (1884): forms H+ in water
    41. 41. DefinitionsJohannes Nicolaus Brønsted & Thomas MartinLowry (independently in 1923): proton donorGilbert Lewis (1923): electron pair acceptorChristopher Kelk Ingold & Robert Robinson (1932):electrophile (electron pair acceptor)Hermann Lux & Håkon Flood (1939): oxide ionacceptorMikhail Usanovich (1939): electron acceptor
    42. 42. Which of the following is anexample of a Brønsted-Lowryacid?1) HCl in acetic acid2) HCl in water3) both 1 & 24) neither 1 nor 2
    43. 43. Brønsted-Lowry acid-basechemistryGeneral Chemistry textbooks focus on this definition of an acid and a base.Acids are proton donors.Bases are proton acceptors.Protons are hydrogen ions. (Note: 99.985 % of the natural isotopes ofhydrogen are H-1. Making H+ out of it results in ONLY a proton present. Thisdoes NOT make acid-base chemistry the same as nuclear chemistry!)e.g., acetic acid is a BASE if it is in the presence of hydrogen chloride (a strongeracid):CH3COOH + HCl ⇌ CH3COOH2+ + Cl-What if you aren’t working in a solvent system with H+?
    44. 44. Which of the following is anexample of a Lewis acid?1) BF3 in the presence of F-(to form BF4-)2) HCl (g) in the presence of NH3 (g)3) both 1 & 24) neither 1 nor 2
    45. 45. Which of the following is anexample of a Lewis acid-basereaction?1) Ca with S to form CaS2) Na with Cl2 to form NaCl3) both 1 & 24) neither 1 nor 2
    46. 46. When to “step in” and“teach”Questions are of increasingly complexityLecture/remediate when 20%+ incorrectOnce objective met, question on next topic
    47. 47. Think-Pair-ShareIndividually:◦ Pick a course and a topic◦ Match the topic to an approachIn pairs:◦ Share chosen approach◦ Design 1 or 2 questionsShare:◦ An example question◦ Describe thought process
