Your Student-centred + GeoGebra Investigations  Comment ... 

What are your reflections on using student-centred files and investigations with your students?
Feel free to write a general comment, or you can specifically mention:

• Tips, traps and obstacles (R2-30/40)
• The Ratio and 3D files (R2-50)
• The Spreadsheet and Statistics Files (R2-60)​

Pythagoras, Spreadsheet and others
The Pythagoras Investigation is brilliant, in my opinion. Sometimes a picture speaks a thousand words and allows students to see visually that other shapes besides a square satisfy the Pythagoras theorem. This brings a lot of credibility to this theorem and s and students are more inclined toward buying into that, rather than accepting it at face value.

The spreadsheet and statistics features are excellent and user-friendly, and I intend to use them more extensively in my lessons. Students prefer to use their graphic display calculators, but I think this will be a good additional tool for them. Demonstrating how efficient this can be will somewhat encourage students to use Geogebra more once they see the effectiveness of this software.

Creating student-centred files is something on my mind now as I am currently doing the MYP curriculum and one thing that I always aim to do in my lessons are inquiry-based lessons with a theme in mind. However, to incorporate inquiry based learning with Geogebra is still quite new to me but I feel more confident in creating some meaningful Geogebra files to allow students to explore various concepts.

Great post. Yes, the Pythag files are a bit of a blowout. I have heard very few teachers say they were previously aware of the principle. Liked reading this: 'However, to incorporate inquiry based learning with Geogebra is still quite new to me but I feel more confident in creating some meaningful Geogebra files to allow students to explore various concepts.'

Spreadsheet
Thank you for that video on the use of the spreadsheet! I have actually wanted to plot points and fit a curve in the past, and tried on Desmos with no success (not saying Desmos couldn't do it, but I certainly couldn't). This is such a useful tool which I will certainly use. As I was posting this, I had a quick look at Excel and realised I could also do this there, but I like the visual aspect with the Graphics window open and an actual Cartesian Plane.
I am feeling more comfortable in creating files now, but still wonder how well students would manage creating their own as discovery learning activities. Initially, I will either use the files with a data projector, or allow students to play with a pre-prepared file and see what concepts they can discover.

The idea would be to partially create the file for them so they don't have to create from scratch. Have them working with only a few new-to-them GeoGebra skills at a time. Make sense Samantha?
