# How to create interactive exercises for Vector Calculus

#### Motivate your students to practice more, for deeper understanding and better results By Pim Bellinga
Co-Founder of Grasple

When it comes to math, there are strong indications that traditional lectures and simply ‘instructing’ students do not suffice. Vector Calculus is no different. To help students fully grasp vector calculus, they need to practice. Online interactive exercises allow your students to do exactly that. While most online practice platforms don’t offer the notation used in Vector Calculus, Grasple does.

In this article, we’ll briefly walk you through all possibilities. We explain how you can easily create interactive exercises for Vector Calculus. Why? Because we believe that by creating interactive exercises as an addition to your (remote) lectures, your students are stimulated to solidify their understanding of your courses.

### Getting started with Grasple

As you may know, Grasple is an online practice platform for higher education. We enable teachers to create interactive exercises, so their students can learn to master various subjects regarding mathematics and statistics, including Vector Calculus.

Getting started with Grasple is easy as pi(e). When you sign up to our platform, you gain access to the Editor. This is where you can create interactive exercises. In your repository, you can create your own lessons, exercises, and courses. When your team subscribes for a paid license (Grasple is free for individuals, but paid for organizations), you can then share it with your students, so they can practice the learning material. Sounds easy, right? It is.

To see what that looks like, click below. Here, you’ll find two examples of advanced Vector Calculus exercises created and available in Grasple.

##### Conservative Fields and Work Example of a Vector Calculus exercise in Grasple. Check it out here.

##### Parallel Vectors Another example of Grasple’s Computer Algebra System. This system recognizes that the vectors (2 1) and (-2 -1) are parallel to each other, so the equivalent answers are accepted. Check it out here.

### Available features for practicing Vector Calculus

When it comes to creating exercises for Vector Calculus specifically, Grasple has a few additional perks. Thanks to our LaTeX editor and available vector notation, you have the opportunity to let your students practice Vector Calculus through an easy interface. This is hard to do in classical text editors. The following features are available in Grasple:

• Vector calculus symbols in LaTeX editor
Using a LaTeX editor allows you to create exercises that require symbols such as nabla, bold vectors, arrowed vectors, double integrals and closed contour/line integrals. Overview of some of the symbols and vector notation available in Grasple.

• Vector notation and equivalent answer checks
We also allow you to create vectors of any size from dropdown menus. These vectors can then be used in calculations. All equivalent answers can be considered correct, unless you specify that only one answer is accepted. This can be especially useful for introductory courses, where you want students to simplify their answers. In Grasple, vector notation can be used from dropdown menus, and can also accept equivalent expressions of a vector. Overview of some of the answer rules that Grasple can use to allow for different types of equivalent answers by students.
