Constructivist introduction to Angles in Geometery, Gender & relationships

Mathematics

There seems to have been a major shift in the TDSB towards a Constructivist approach to teaching Math.  What is that?   Consider this definition:


"Students need to construct their own understanding of each mathematical concept, so that the primary role of teaching is not to lecture, explain, or otherwise attempt to 'transfer' mathematical knowledge, but to create situations for students that will foster their making the necessary mental constructions." (from http://mathforum.org/mathed/constructivism.html)

I am of two minds on this approach.  In the photo below, the class used some prior knowledge of angle relationships (check out the photo of KWL chart) to work on this investigation.  We took up the answer and talked about it but, as I write this, I realize that a more detailed lesson will need to supplement this.   

Some of these videos fill in the theory related to this investigation, but it is not a substitute for a solid review of these topics.  This will happen on Monday.

My version of a note, recorded by the students

I am going to look at the homework I assigned on Friday and make a few notes on the questions and then repost them on Google Classroom (GC).  This may be helpful to some students who found it initially a little confusing.  I will do this before 7p.m.

As for my commentary on Constructivist approaches, that will also have to wait but here is a small commentary, in the form of an editorial cartoon:

I wouldn't agree and suggest that Constructivism is a "Weapon of Math Destruction."  That is quite an extreme assertation.  There are benefits to investigating and trying to make sense of Mathematical challenges.  At the same time, I do believe there is a much needed place to learn foundational skills, which have unfortunately been referred to as a drill and kill approach to Math instruction.  Balance, will all things in life, is key.  It is not intent to write an essay here, but I thought I would share my thoughts on the matter.  

After completing the first portion of homework, we will come back to this detailed video.  There is a lot of information in it, so become overwhelmed!

This will need some editing for today's lesson (Monday, 29th) but this will be part of today's and next week's discussion:  https://www.plannedparenthood.org/learn/sexual-orientation-gender/gender-gender-identity/what-are-gender-roles-and-stereotypes  We will be examing, in part, how our ideas on gender may influence how we relate with one another and how we can strive to build healthier relationships with one another.
