This is a very large collection of videos that work out math problems. They are categorized by course: Algebra, Arithmetic, Calculus, Differential Equations, Discrete Math, Linear Algebra, Probability and Statistics, Trigonometry, and Misc. The videos are under ten minutes long and the collection covers most of the types of exercises that students will see in their courses, especially algebra and calculus.
Type of Material:
Provides a tool for students to use when learning how to solve a number of different types of mathematics problems.
The videos are all hosted on YouTube and embedded in the author's website, so they should play on any device.
Identify Major Learning Goals:
Review how to solve mathematics problems watching videos.
Target Student Population:
Any mathematics students from basic arithmetic up through differential equations.
Prerequisite Knowledge or Skills:
Based on the video chosen, the student may need knowledge previous to that level of math.
The site contains a large collection of math videos. A specific math problem is solved based on the title chosen. The videos are relatively short - most less than ten minutes. The videos are good with only minor spelling errors in some of the videos. The pace works well for students who want to quickly see an example of a problem that they are working on. The example that are chosen are effective in demonstrating the key concept that is being demonstrated.
An instructor should carefully select the videos and assign them to the students. Not every video follows the way the instructor may teach the material and could result in confusion for the student.
Potential Effectiveness as a Teaching Tool
The instructor states the main learning goal and goes through the steps of solving the problems providing a verbal explanation as he works through the problem. An instructor could make excellent use of these videos in a classroom or online class. This collection can serve as an effective resource for students to use as they are working through their homework. The breadth of the collection is admirable, especially in the algebra, trigonometry and Calculus areas.
For many of the videos, the closed captioning does a terrible job translating what is said on the videos, especially when variables are referenced. This can be problematic for accessibility reasons. An instructor should carefully select the videos and assign them to the students. Not every video follows the way the instructor may teach the material and could result in confusion for the student.
Ease of Use for Both Students and Faculty
The videos are accessible from any website, tablet, or cell phone because they are uploaded on YouTube. The instructor's voice is clear and easily understood, as well as his writing. Students will have no trouble accessing them whether they are at their computers or their smartphones. The videos themselves are engaging and the instructor’s writing is clear enough to read.
The layout of the webpage does not make it easy for students to find the video that they are looking for. With so many videos, it would be better to include subcategories that are linked from a list at the top. For example, under algebra there are hundreds of videos that are just listed under “Algebra”. We would like to see mistakes completely erased and not scribbled out.
