Sem 1 planning (day by day)

Page history last edited by Jay 12 years, 8 months ago

Overview

Required resources:   

DPS (DP subject guide), SG (Allott's study guide), WB (Senior Biology workbook), Tig (DP bio course companion)

 

date day A - HL/SL-y1
 E - SL - y1
Aug 8-15 1

Needed in advance

  1. data set of all DP biology grades (exams & IA)

Learning Process

  1. Review new GSIS weekly schedule (esp. extra hours)
  2. Introduce subject guide (download above)

first class

  • wiki
  • assessment statements
  • intro to data (barely)
  2

DATA

 Goals:  recognize, calculate and use - normal distribution, mean, variability, standard deviation

Process:  Use DP test data to determine these values

Product: Students produce a spreadsheet and a worksheet with these values calculated: A_meangrades_name  

t-test; CE

Goals:  Connect processed data to drawing conclusions about information

Process:  View Taylor's statistics presentation.

Product: Students produce unique Google Doc (or Excel) in which they graph hummingbird data (from Taylor's presentation; above.)
  extra hour

Stats assess statements

Process:  Begin view Taylor's statistics presentation (only got as far as seeing humminbird data, calculating mean & SD on calculator, then making table in SS of data and determining mean & SD in SS

Product: Students produce unique SS (see above)

Practice: Stats Practice 1, Stats Practice 2 & Stats practice 3

Later: Presentation on t-test

 

-  none  -
  3

Goals: ... practice STDEV calc on calculator in class).

Assignment: (1) Use hummingbird data to make spreadsheet in which they calculate mean and STDEV using formula:  A_errorbars_name

(2) Make graph of data with error bars, labeled axes, title, etc.

(3) Each student make and share Screenr screencast of making the graph:

  • email to teacher as Screener link;
  • email spreadsheet as A_errorbars_name
  
  4

Goals: STDEV calculation & understanding (instructions for STDEV on Ti-84 calculator)

  • demo two data sets with dif variabilities
  • BZ p 35 has data set for discussion
  • students calculate mean +/- 1 sd; mean +/- 2 sd; etc
  • ended with calc mean & stdev in Google Doc, stats practice 3
[next - introduce t-test: difference between means signif or not]
 
Aug 16-23 5

Goals: What is a t-test? (click here for Ti-84 instructions); Ho (test 2 pops); do a t-test

  1. Practice calculating STDEV with calculator
  2. practice determining mean +/- 2 STDEV
  3. Introduce "difference between means of 2 populations"
    1. Ho = null hypothesis (no difference or small difference caused by chance)
    2. Ha/H1 = hypothesis ("significant difference" or  caused by specific effect)
    3. control =
  4.  

• t-table here

• Mr. Reimer's Screenr "T-test in Numbers"

• Youtube "how to do t-teest on spreadsheet"

• Youtube "technical info on what a t-test is" for math geeks
