	One of the things that teachers worry about when doing enquiry based activities in the classroom is the unpredictable nature of the work that students may produce. Watch the following video and discuss the ways that you might react when a student produces an interesting but unexpected graph.

	{{~~activity\|Small group activity\|20~~}} ~~Get into your small group of last week’s ‘making use of enquiry ideas A-E’ activity to discuss your homework tasks.~~		{{review of follow up}}

	~~'''Part A:''' (5 mins) You were asked to try out a mini-GeoGebra enquiry lesson in your class. Discuss in your small groups the following questions:~~

	*How did your students respond to the open nature of this task?
	*Did you feel confident with teaching using GeoGebra? Why or why not?
	*What other observations can you make that will help you evaluate the use of Geogebra?

	'''Part B:''' (15 mins) Invite colleagues to share how their extended enquiry-based learning (EBL) lessons are going. They could do this by giving PMIs of '''at least two''' of the following considerations of a successful EBL lesson:
	* Nature of enquiry tasks (e.g. are they open-ended enough so that students could also take some responsibility to research and find ways to investigate different enquiry ideas, rather than just producing an answer or a solution?).
	* Students’ involvement in framing enquiry tasks and questions (e.g. can you persuade students to ask more questions without feeling shy or stupid?).
	* Students’ engagement and competence in conducting an experiment, searching for information or resources themselves.
	* Students’ engagement and competence in interpreting the information or data themselves.
	* Teacher’s role as a guide and co-learner with the students.
	* Availability and accessibility of resources (e.g. internet).
