Experiments at Level 7 Auckland Mathematics Association 2011 Anna Martin Avondale College
Basic overview • Pose a problem that will require an experiment to investigate • Write a plan for the experiment • Carry out the experiment and record data • Analyse the data • Answer the investigative problem • What could possibly go wrong?
WORKSHOP GOALS • Outline process for increasing understanding of new curriculum and associated assessment standards • Share planning for experiments at level 7 • Increase understanding of different types of investigations involving experimental situations
SYNTHESISING AVAILABLE INFORMATION • NZC • Teaching and learning guides • Draft standard • Exemplar tasks (and annotated student exemplars) • Matrix • Workshops
What do students need to Learn • Different types of experiments • How to pose a question for an investigation that needs an experiment • How to plan an experiment • How to explore data from an experiment • How to consider and use variability • How to write a report
EXPERIMENT? • Identify which of the following are experiments, and if so, what kind of experiment. • Describe what should you be looking for in the data.
EXPERIMENT? • What is the relationship between people’s “before exercise” pulse rates and their “after exercise” pulse rates?
EXPERIMENT? • What is the relationship between the height balls are dropped from and the height of the first bounce?
EXPERIMENT? • What is the relationship between the length and maximum circumference of carrots (or other fruit or vegetable?)
EXPERIMENT? • What is the relationship between people’s cubit lengths and their heights? (Cubit length is from elbow to tip of middle finger.)
SURVEY TIME • Is the number of assessment standards (for all qualifications not just NCEA) offered by NZQA greater or less than 5 000? • How many assessment standards do you think are offered by NZQA?
SURVEY TIME • Is the number of assessment standards (for all qualifications not just NCEA) offered by NZQA greater or less than 15 000? • How many assessment standards do you think are offered by NZQA?

ACTIVITIES TO ENCOURAGE EXPERIMENT IDEAS http://www.phy.ntnu.edu.tw/ntnujava/index.php?PHPSESSID=n3u00b69q2eai42bcanvnk1t74&topic=387.0
TESTING PROCESSES • Myth busters episode on whether it is possible to shoot a ball out of the back of a car at the same speed the car is moving forward so that relative motion is zero.
IDENTIFY and DESCRIBE STEPS IN THE INVESTIGATION • What was the investigative question? • What type of experiment was used? • How many trials were competed OR how many experimental units? • How was the data collected? What measurement tools were used? • What analysis was completed? • What conclusions were made?
