## 1 Blackboard vs PowerPoint

Do you use a **Blackboard** with chalk, a whiteboard with a marker, or do
you use a PowerPoint presentation?

For centuries, educators taught math on a **Blackboard**. It is the most
efficient method to deliver math methods and ideas to your class.

A presentation on a **Blackboard** is engaging and dynamic. It adapts to
what is happening in your class. It is well-paced. It never goes
overtime.

A **Blackboard** presentation can show the most intricate details of a
mathematical argument.

A **Blackboard** presentation shows one simple step at a time. It
allows your students to digest the idea and ask questions before going
to the next step.

Unfortunately, we often see the **Blackboard** method replaced by
PowerPoint, and it is rarely good.

As a rule, a PowerPoint presentation is often poorly structured and poorly delivered.

It is often overloaded with content and goes over time.

It is always shallow on details and rarely goes beyond a simple list of bullet points.

Due to the multi-page structure of a PowerPoint presentation, a presenter needs to flick back and forth between pages to reference earlier content.

Such structure is incompatible with the essence of mathematical argument and impossible to follow.

## 2 Re-usability

PowerPoint has only one advantage over the **Blackboard**: `re-usability!`

Re-usability is the only reason why PowerPoint is becoming so
ubiquitous. Re-usability is **convenient**. Apart from re-usability,
PowerPoint has little value to a math educator.

This project aims to add what is missing in the traditional **Blackboard**
teaching method. It combines all of the advantages of a **Blackboard**
with the one missing element: **re-usability**.
