EDCP 342A Unit planning: Rationale and
overview for planning a 3 to 4 week unit of work in secondary school
mathematics
Your name: Hemlatta Engineer
School, grade & course: Seaquam Secondary School, Grade 12 & Calculus.
The topic of unit: Exponential and logarithm functions
Preplanning questions:
(1) Why do we teach this unit to secondary
school students? Research and talk about the following: Why is this topic included in the curriculum? Why is it important that students learn it? What learning do you hope they will take with them from this? What is intrinsically interesting, useful, and beautiful about this topic? (150
words)
The topic is included in the curriculum because Exponential and logarithm functions develop the concept of instantaneous rate of change. It is important that students learn the topic so that they can apply them to solve the growth and decay problems. I hope students will learn from the Exponent and logarithm functions unit that how to model real-world situations.
Exponential functions are helpful with phenomena that change very quickly or that grow or decay by percentage over a particular time period. In many of the sciences, certain quantities grow or decay at a rate that is proportional to their size.
Logarithm functions are helpful when working with phenomena that have a very wide range of values that students actually work within a smaller range. The Logarithm functions that are used to measure the magnitude of earthquakes. The magnitude of an earthquake is related to how much energy-related by the quake so that we can save human lives by predicting the after sock the earthquake’s effects.
|
(2) A mathematics project connected to
this unit: Plan and describe a student mathematics project that will form part of this unit. Describe the topic, aims, process and timing, and what the students will be asked to produce, and how you will assess the project. (250
words)
The
Process of the project: The project is all about comparing the Exponential function and logarithm function. The project helps students to connect math to real-world situations such as the growth of population, the growth of bacteria, sea level raise, temperature raise, weather forecasting, or university fees raise.
The
students will be asked to choose one of the above-mentioned situations for the project. They will create an equation by using a story/word problem, draw a
graph, present the PowerPoint presentation/model/poster and compare the exponential function’s equation with a logarithm function’s equation or vice a Versa.
The project helps students to understand the topic by creating the equations, by
comparing the properties of the two functions, and making scientific
conclusions based on mathematical justification.
When
I will give the project to students, I will allow students to work either in pairs, or small groups or individually. I will give clear instructions on what is expected to do during the project and give a day to think about the project and ask them how they want to do the project, how they want to work. I will check the status of their process on the project regularly. They will submit the project after the week.
I
will assess the project by giving mark and feedback when they will share
their projects with the class as a group.
|
(3) Assessment and evaluation: How
will you build a fair and well-rounded assessment and evaluation plan for this unit? Include formative and summative, informal/ observational and more formal assessment modes. (100 words)
I will build a fair and well-rounded
assessments and evaluation plan for this unit by below mentioned three
assessment modes.
I will check their comprehension by giving
homework for practice (1% marks/ lesson), by taking the midterm quiz (20 %
marks), by giving project (35 % marks), and by taking the final exam at the end
of the unit (35% marks).
I will evaluate their understanding by
reviewing the lesson at the end of each lesson. I will check in with each
group when students are doing during the activities and during the project
presentation. I will take the midterm test
to evaluate students’ progress, and I will take the final test how well they
understand the concepts of the unit.

study the orbit of the Moon.

Worksheet (link), Exit ticket activity for the Project and project's rubric:
Exit ticket activity: What’s Your Function
We are going to work on a project with a partner today. The
project is about creating our own functions to model different scenarios in our
communities.
For today’s exit ticket, please work with a partner and
brainstorm at least 3 different scenarios that could be
modeled with a function. Identify the variables in the function and hypothesize
what type of function would best model the scenario. An example is provided below:
Example:
Scenario: Average temperature by month in Vancouver,
BC.
Variables: Month (x-axis) and Temperature (y-axis)
Type of Function: I think this function is best
modeled by an exponential function
because the temperature is low in January, gradually increases as we get to April
and July.
