The simulation that I used was for quadratic functions. The simulation allows the students to manipulate the coefficients of the different variables when the equation is in polynomial form. The students can also see how the intercepts, line of symmetry and the vertex changes as the coefficients do.
Learning objectives addressed
By doing this simulation, the students can gain a full understanding of how the coefficients change how the graph looks. The students can see which coefficients effect what attributes of the graph. In the simulation, the students pick which coefficients to change and can easily see how the graph is changed. The set of questions that go along with the simulation force the students to figure out which coefficients they need to change in order to answer the questions.
Interest level for students
This simulation is a great tool for visual learners or any student that is having problems with the material. The simulation is not one that would really engage the students however. The simulation is there for a guide for the students to understand the material. It is not really a tool to get the students more interested in it.
Ease of use
This simulation is very easy to use. The three coefficients are represented by three bars which the students can change simply by dragging the ball. When you are dragging the ball for each coefficient, you can instantly see the change in the graph. This simulation can be used with very little instruction for the students.
Usefulness
This simulation is very useful for the students because gives them a great visual for how the different coefficients effect the graph. The students can see instantly how each coefficient changes the vertex, intercepts, and axis symmetry. This can be a great tool for visual learners or for anyone that is struggling with this material.
