Hey kids! Here’s Dr. Binocs with a bag of five senses. Do you know what are the five senses of a human being? Have you ever wondered how important are your eyes, ears, nose, tongue and skin? Join Dr. Binocs as he tells you more about the five senses.
An algorithm is a mathematical method of solving problems both big and small. Though computers run algorithms constantly, humans can also solve problems with algorithms. David J. Malan explains how algorithms can be used in seemingly simple situations and also complex ones.
In this video we will outline what pseudocode is used for in computer programming.
OCR GCSE Computing MOOC video exploring the Algorithms in pseudocode and flow diagrams.
Flowcharts are a useful design process – here we give an overview and examples
A basic guide to identifying components and their functions for those who are new to electronics. This is a work in progress, and I welcome feedback from you guys on whether I should break it down into more manageable chunks. I’ve kept the maths to a minimum, since it can be off-putting to someone just getting started in electronics. The idea of this video is to slot in some more of the jigsaw pieces involved in learning electronics, when you start to recognise components, but aren’t quite sure what they are or what they do. It’s tricky to squeeze…
In this video I will explain why coils/inductors are so important in different DC circuits. I will talk about magnetic fields (MF), induction, Lenz Law and inductance. The example circuits include: boost converter, buck converter and flyback diode protection.
In this video I will explain what reactance means and how you can calculate the amount of reactance for a coil. I will also talk a bit about reactive power and phase shift.
When I mentioned to people that I was doing a video on transistors, they would say “as in a transistor radio?” Yes! That’s exactly what I mean, but it goes so much deeper than that. After the transistor was invented in 1947 one of the first available consumer technologies it was applied to was radios, so they could be made portable and higher quality. Hence the line in ‘Brown-eyed Girl’ – “going down to the old mine with a transistor radio.” But more important to our lives today, the transistor made possible the microcomputer revolution, and hence the Internet,…
The working of a DC motor is well explained in this video with the help of animation. Construction details of DC Motor, Shunt & Series motor, concept of back EMF are also explained in this video.
How a Stepper Motor Works, basic working principles, driving modes and Stepper Motors Types by Construction.
Computational thinking will be a fundamental skill used by everyone in the world. To reading, writing, and arithmetic, lets add computational thinking to every childs analytical ability. Computational thinking is an approach to solving problems, building systems, and understanding human behavior that draws on the power and limits of computing. While computational thinking has already begun to influence many disciplines, from the sciences to the humanities, the best is yet to come.Looking to the future, we can anticipate even more profound impact of computational thinking on science, technology, and society: on the ways new discoveries will be made, innovation will…
Learn about what abstraction is and how it helps us to solve problems.
Design thinking is a design process that enables us to solve complex problems. It combines deep end-user experience, systems thinking, iterative rapid prototyping and multi-stakeholder feedback to guide us through the successive stages in our design.
Reaching a widely diverse group of students requires flexible means and methods. These “Five Rules of Design Thinking” will help any teacher find new ways to approach the important work of providing quality educational opportunities to each and every student. Careful attention to the design process has the potential for overcoming many barriers before they become obstacles to student achievement. The “Rules” come from the lives of historical figures and examples of the barriers that they faced, and the unique ways they overcame them. We can use the same ideas today. Michael Roush specializes in educational technology, assistive technology,…
In this unit, students learned about the external parts of different animals that help them meet their needs and survive in their specific environment. These parts help animals see, hear, grasp objects, protect themselves, and move from place to place. Their parts also help them seek, find, and take in food, water and air. The goal of the unit was for students to design and create the “ultimate” animal that can survive in any environment. They used the design thinking process to develop a problem sentence, find a solution to the problem, and prototype their solution. The process involved students…
