Enhancing student engagement in Algebra I classes, especially when it comes to solution verification, can be quite a task. However, the integration of short Python scripts for checking answers not only makes the process enjoyable but also introduces students to the basics of coding. Using Python in the classroom can improve academic performance and problem-solving skills, aligning with the Math Common Core standards for technological integration.
The use of Python has the potential to ignite a passion for algebra among students, as many find coding in Python to be an entertaining activity. I have observed that students who were previously unresponsive to the concept of algebraic variables became more engaged once they had experience with Python. No prior programming experience is needed for either educators or learners; the setup is quick and straightforward. The only requirements are a basic understanding of Python, the specifics of our answer-checking program, and some fundamental troubleshooting skills.
Incorporating Python into Education
In my Algebra I class, which includes students with special educational needs, several have mentioned that Python has turned math into their favorite subject. They found traditional math classes to be reminiscent of monotonous worksheets, but solving math problems on a computer made the experience more enjoyable and less classroom-like. I have also taught general education STEM courses, including AP levels, and have seen similar positive results with the inclusion of Python. Introducing Python coding can revitalize various courses for students of all kinds.
To start with Python, you will need computers with internet access. While it's possible for teachers to install Python on school computers, I recommend using JDoodle, a free online platform that is more convenient and adequate for our purposes. Setting up an account with JDoodle simplifies the process for both students and teachers. Once JDoodle is ready, you can begin exploring Python.
Mastering Basic Coding Concepts
Our goal is to gain enough Python knowledge to understand the code structure, modify the code for different algebra problems, and resolve any issues that may arise. After setting up Python for your students, teach them the core elements of the language, such as variables, equations, and output. We focus solely on the Python aspects necessary for understanding our algebra-checking program. My students were able to tailor the program to verify their answers.
Variables: In Python, variable declaration is not necessary, which is a distinctive feature compared to many other programming languages. You can simply assign values using an equal sign; for example, sum = 2 + 2. The variable (sum) being assigned is always placed to the left of the equal sign.
Equations: A key Python concept is mathematical equations. In Python, these are quite simple: + for addition, - for subtraction, * for multiplication, and / for division. We will only review the operations necessary for the algebra we're working on to check answers. I suggest using parentheses to facilitate code checking and minimize errors.
Creating the Code
With a foundational understanding of Python, we can now apply this knowledge to our answer-checking program. Here's the code for verifying an answer to a sample problem: 6x + 2 = 20.
Line 1: x = 3
Line 2: if (6 * x + 2 == 20):
Line 3: print("You did great.")
Line 4: else:
Line 5: print("Try again!")
We will systematically learn the function of each line of code.
Line 1 assigns a value to a variable. In this case, the value of x in our program is set to 3, representing the students' answer from their independent work.
Lines 3 and 5 are in charge of printing output to the computer screen.
