Logarithmic Function

Course Information
  • Course: Mathematics
  • Class: 11
  • Duration: 40+40 min
  • Technological Equipment: a computer (that belongs to either the teacher or students), overhead projector, a tablet PC or smart phones.
Course Content Logarithm function and its graphs Learning Outcomes At the end of the course, students will be able to:
  • Form a logarithm function as the inversion of an exponential function.
  • Tell to which continuum the exponential and logarithm functions given are symmetrical.
  • Examine the circumstances in which exponential and logarithm functions increase and decrease.
  • Draw the graph of
Course Objectives and Assessment Students will form the graph of a logarithm function and examine the change for various values of the function. 
  • Available instructions in the Geogebra program are used to form a logarithm function.
  • Students are given a chance to practice as much as possible.
  • Students’ records are kept for assessment.
  • Depending on the results, students are provided with more practices.
Learning Strategies An exponential function is formed.   
  • A continuum of y=x is drawn. The points that are equally far from this continuum are identified and a graph through these points is drawn.
  • It is expressed that the graph formed is the logarithm function itself.
  • Under the conditions in which a logarithm function is defined, students are helped to
discover an increasing function for a>1 and a decreasing function for 0<a<1. Depending on the value a takes, the changes in the logarithm function graph is examined.
  • Technology will be integrated when the students have practices. Student practices will be
printed out. Necessary feedback and correction will be projected via the projector. Resources A text book.  Integration of Technology The Geogebra program is introduced to the class in advanced.  Practices are done in a class with a reliable internet connection. In case there is a technological problem (such as the lack of internet access), practices will be done off-line. Besides, the hard copies of the practices to be done on the program Geogebra are printed out in advance. In case of a problem with the available technical equipment, the lesson will be conducted over these copies.
