Presentation Transcript

  1. A: 7 September 2011 • Welcome to Chemistry! • Objective: • Demonstrate mastery of the single speaker rule • Make observations and inferences • Identify pieces of chemistry safety equipment and their uses. • Do now: • Pick up a syllabus from the kidney table. • Find your seat.

  2. Agenda • Welcome! • Demos and observations • Syllabus: materials, bathroom, tardy policies • Another demo and more observations • Lab safety equipment and uses • Lab safety scenarios Homework: Lab safety scenarios: Thurs., Syllabus signed by Friday

  3. Welcome to Chemistry • Ms. Boiteau

  4. Single Speaker Rule • We all have a right to be heard. • We all have a right to contribute. • But does everyone have these rights all at the same time?! • We must extend these rights to everyone. • How do we do this in a large group? • Raise your hand • Wait to be called on. • Listen actively and silently to the speaker.

  5. Demonstrations • Expectations: • Raise your hand to contribute • One speaker at a time • Listen actively to the speaker • What do you observe? • What do you think is happening? • Is this chemistry? Why?

  6. C: 7 September 2011 Objectives: • Demonstrate mastery of the single speaker rule • Make observations and inferences • Identify pieces of chemistry safety equipment and their uses. Do now: Pick up a syllabus and find your seat!

  7. Agenda • Syllabus: materials, bathroom, tardy policies • Demo and observations • Lab safety equipment and uses • Lab safety scenarios Homework: Syllabus signed by Friday

  8. Syllabus • Materials • You’ll need: • $10 for a notebook • A two-pocket folder • Pens and/or pencils • A calculator • By Friday!

  9. Tardy? • Sign in on the clipboard on your right near the door. • 3 tardies = blue slip; each subsequent tardy = blue slip • You must be seated when the bell rings to be on time. • More on the first five minutes of class tomorrow…

  10. Bathroom • You have seven bathroom/drink passes per semester. • You may ask to go anytime we’re not doing something as a whole class: • Individual work, partner work, group work, labs… • You keep track on the clipboard by the door. • Write yourself a pass with complete information. • Each unused bathroom pass = homework bonus point at the end of the semester!

  11. Making observations • Single speaker rule to share your observations.

  12. Lab Safety Map! • Stroll around the room, identifying lab safety equipment. • Sketch it on the map on your handout and label with the name. • Then, we’ll discuss each piece of equipment and it’s use!

  13. Safety shower • Extinguishes fires and washes away large chemical spills on the body

  14. Eyewash Station • Flushes chemicals and debris (bits of glass or other materials) out of the eyes.

  15. Fire extinguisher • Put out fires

  16. Fume hood • Removes smoke and fumes from chemical reactions, filters them, and recycles the clean air.

  17. Sink • For washing hands after every lab, and flushing minor chemical spills

  18. Smoke detector • Indicates an unsafe level of smoke and/or fire in the room

  19. Gas shutoff valve • Turns the gas supply on or off to the entire room.

  20. Goggles • Protect your eyes from chemical splashes!

  21. Lab safety scenarios • With your partner, read each scenario. • Write down what you’d say to the student involved about how his or her action does or doesn’t meet lab safety expectations. • Be ready to share your scenario with a little skit. • When you finish, read through your syllabus.

  22. Homework • Lab safety scenarios: Thurs. • Syllabus signed by Friday

  23. Objective Mastery Grading • For each unit, you will receive a checklist of the objectives that you must “master.” • You are responsible for recording your mastery of each of these objectives on exit tickets, quizzes, tests and exams. • Your goal is to earn a 3 or 4 (out of a possible 4) for EVERY objective.

  24. But, what is a 3? What’s a 4? • Here’s the scale: 0: You are unable to show any knowledge of the objective, even with help. 1: You correctly answer easier questions with help. 2: You correctly answer easier questions without help. 3: You correctly answer easier and more challenging questions without help. 4: You correctly answer application or explanation questions beyond those discussed in class.

  25. What does a quiz look like? • A few easier questions • Identify, list, etc. • A more challenging question • Problem solve, explain, etc. • An application or explanation question beyond what we discussed in class.

  26. So, for example Objective X: SWBAT identify the reactants, products and purpose of photosynthesis. • 1. Name the two products of photosynthesis 2. Give two examples of organisms that do photosynthesis. • 3. Look at the drawing to the right. (Drawing of a plant in a flask.) Over time, what would happen to the level of oxygen in the water? Why? • 4. If you placed that flask in the dark, what would happen to the level of oxygen in the water? Why?

  27. So how would you be graded? • Yes, half points are possible.

  28. A note about level III questions • Level III questions go BEYOND what you learned in class. • They ask you to apply what you learned in class to a new situation that we didn’t discuss in class, or to explain something that we didn’t discuss in class.

  29. Wait. • So, to get 100%, I have to know MORE than we learned in class? • Unfair. • A 4 out of 4 does NOT equal 100%. • A 3 out of 4 does NOT equal 75%! • So how are you graded?

  30. Most importantly • Forget about percents. Really. What do they really tell you? • Focus on earning a 3 or 4 on each exit ticket, quiz or test section. • THAT means that you have MASTERED that objective. • You really GET IT! :D • Isn’t that what learning is really about?

  31. But, you still need a grade. • Let’s say that, in a certain unit, there are 10 objectives. • You earn a 3 out of 4 on eight of those objective quizzes. • You earn a 4 out of 4 on one of those objective quizzes (good job!) • That means that you reached mastery for nine out of ten objectives. • Your quiz average is a 9/10, which is equal to…

  32. What if I don’t reach mastery? • Sometimes you don’t get it on your first try. • Come for extra help (Tues. and Thurs. from 3:30-4:30). • Make an appointment with Mr. Lerner. • Ask a question in class. • Talk to a friend who did reach mastery. • THEN retake the quiz.

  33. What about a test? • A test is just a bunch of quizzes put together. • There are no re-takes, so use your time during the unit to master each objective BEFORE test time! • Your grade on a test is based on the percent of objectives that you earned a 3 or 4 out of 4, with some bonus thrown in for earning 4’s.

  34. Track your mastery • When you get an exit ticket, quiz or test back in class, we will take a minute to record our objective mastery on the checklist. • This checklist is your guide to keeping track of what you GET and what you don’t.

  35. Focus • The focus here is on mastering objectives, not a grade.

  36. Questions? • Ms. Boiteau, this is • Awesome! • Crazy. • Confusing. • Standing in my way of seeing 100% written on the top of every paper I get back, the only thing that makes me happy in life.
