Sine and Cosine graphs

-

A lot of times students are not ready for using resources that they are expected to by the curriculum. I faced that when my IB SL Maths students had to use the graphic calculator to learn about Sine and Cosine graphs. 

 They were students who had just come from CBSE or ICSE background and were not used to the usage of calculators at the IB level. Their comfort zone was shaken and stirred!

 I did what any empathic teacher would do. I broke the challenge into baby steps!

  1. They drew the curves on graph paper, just like good ol days! 
  2. THEN we went on the CD, projected onscreen, and saw the graphs and their changes in detail. I kept keying different values and they saw the changes in the graphs.
  3. Finally I asked them to pick up their graphic calculators and try some curve drawing using them.

The fascination and comprehension in their eyes was enough to feel contented!

 No fear. Only excitement. The tech friendly generation got it right within minutes!

Judge a man by the questions he asks!

Judge a man by his questions rather than his answers. (Voltaire) All our lives, we have been told that our smartness is measured by the answers that we have. And here comes Voltaire who says the opposite! My initial reaction is, ‘What does this mean?’ However, since it is Voltaire that says it, I think it must have some meaning and I dig deeper! As a listener, I may learn more by the questions I ask instead of by the quiet judgments I make. As a reader I may gain more by my questioning the text instead of believing what I read blindly. As a human being, I may contribute more to society by questioning the traditions than blindly following them. “The questions do mean a lot in life, not just for the sake of saying it, but for the sake that they define where your life is headed and how you are going to shape your life”, (Inspire99, 2019, para. 5) . As I read this blog piece, I felt pieces dropping in my mind and a change in the way I approached questions. Questions as a way to

Discipline models in classroom

There are several models of discipline by different theorists. However, they can be broadly categorized  as (a) low approach, with low degree of teacher control and high degree of student control; (b) medium approach, with medium degree of approach for both; and (c) high, with high degree of teacher control and low degree of student control. Fay and Funk/ Low-control/Guiding model Jim Fay and David Funk focus to “create a classroom environment in which students can develop their own self-discipline and independent problem-solving skills” ( Models of Discipline Low Approach,n.d. ). The objective is for teachers to learn “ techniques to avoid arguments and power struggles”, ( Delosio, 2008 ). These are based on 9 essential skills for teachers which are, “(a) Neutralizing student arguing, (b) Delaying consequence, (c) Empathy, (d) The recovery process, (e) Developing positive teacher-student relationships, (f) Setting limits with enforceable statements, (g) Using choices to prevent po

Maths Magazine Project

PROJECT – CREATING A MATH MAGAZINE FOR SALE    This is a classic example of a project through which a girl, having found her niche, also found her relation with the subject.  It is her magazine that is attached.  She came to my class very scared of math.  So much so that she would start crying.  It is through these projects that she overcame her distaste of the subject and went to the extent of taking a class one day and taught algebra!  AIM:   To take an overview of the topics done in the 1st term.  To be able to express them in their own words. T o elicit inherent creativity of linguistic expression. To improve the grip of the math concepts covered.  MATH INVOLVED:   Fractions (addition, subtraction, multiplication, division, applications) geometry – few properties decimals (addition, subtraction, multiplication, division, applications) directed numbers (adding them using number line)  INSTRUCTIONS GIVEN TO STUDENTS:   Make a MATH MAGAZINE
