I built this for my class to try to understand the difference between simple and compound interest and also how to setup a spreadsheet with good design.
Image Credit Follow on In the previous post ( link to part 1 ) I discussed the basic mathematical ideas to have in mind when thinking about purchasing a car. I had decided I would look at cars in the range of 80 - 100 000 rand and I wanted to buy a used car because of the better value offered. The videos in post 1, suggest cars around the range of 2 - 4 years old, as they offer the best trade off between future maintenance costs and depreciation on the purchase price after you have bought it. I agree with the facts laid out and will probably look for something in the 3 to 4 year old range. However I still need to check to see if the same patterns on maintenance costs and depreciation are also true in the South African context. This points to our next step in our search. How do we get accurate information relevant to the SA context to see if these ideas mentioned are true and so allow me to get closer to my ultimate goal, buying a car. I am going to start with an internet search to
Intro Here are a collection of links that give great advice on how to track down academic information efficiently over time. It could be particularly helpful for postgraduate students who are finding the accessing and sorting of academic information overwhelming. https://paperpile.com/g/academic-search-engines / https://paperpile.com/guides/research / https://paperpile.com/guides/writing/ https://paperpile.com/g/search-online-research-database/ https://paperpile.com/g/academic-research-databases/ https://paperpile.com/g/google-scholar-guide / https://paperpile.com/g/search-online-research-database / https://paperpile.com/g/eric-research-database/ https://paperpile.com/g/what-is-research-paper/ https://guides.library.ucla.edu/databases/choosing
Introduction At the beginning of this year I tried out a new way of discussing and defining my classroom Rules with my learners. It was by no means perfect, but it felt like a breath of fresh air compared to the top down heavy authoritative processes I had used before. The purpose of this post is just to define the basics of what I did and to open the concept up to other teachers so it can be further refined through collaborative discussion. Below is a brief description of how the process works. Learning Goal Using collaborative discussion and negotiation to create a set of rules for the classroom that everyone believes are in their best interest to abide by. Learning Materials Two different colour post it notes, whiteboard, board markers. Method Ask students to think about what they feel are the DO’s & DONT’s of a successful learning space. Then hand out 3 post it notes of each colour. Define one colour for DO’s and another for DONT’s. Then ask the students to w
