### Learning Maths in Context

This booklet introduces teaching and learning resources for learning mathematics in context in relation to Construction and the Built Environment (CBE), Creative and Media (CaM), Engineering, Information Technology (IT) and Society, Health and Development (SHD).

The resources are of interest to teachers who...

### Stem Cells and Diabetes

Produced in 2015, this resource looks at how stem cell research is moving towards a therapy for diabetes and uses case studies of real scientific data to exemplify current work in the field. The resource also highlights the inter-disciplinary, collaborative and international flavour of contemporary...

### Data Representation: Bitmap Images

Using a spreadsheet as a grid of 'pixels', this computing activity teachers how 1's and 0's can store image data. The classroom exercises use images with increasing pixel resolution, looking at how this affects the clarity of the image. Moving from black-and-white images, the students then use grids of colour...

### Probability: Balls in a Box

The presentation presents a box containing m white balls and n black balls. Students are asked to explore the probability that if two balls are chosen consecutively, without replacement, the two balls are the same colour. A spreadsheet simulating the situation is provided to enable students to experiment. The...

### Discrete Random Variables: DRVs from a Bag

This exercise is designed to ensure that students know how to find the expected value, E(X), and the variance, Var(X) for a discrete random variable, and that the probabilities in a probability distribution always add to one. Students are given a selection of numbers and are challenged to establish those...

### The Poisson Distribution: Adding Two Poisson Distributions

In this resource, students consider whether two Poisson distributions can be added together to form a third Poisson distribution. The initial, discussion generating proposition is backed up by a proof. The resource also contains an accompanying spreadsheet on which students can run simulations to test the result....

### Sampling and Hypothesis Testing: Significance Levels

This activity is designed to deepen understanding of hypothesis testing. Students are presented with a coin which is suspected of being biased. A hypothesis test is set up. A results table is shown giving the significance of the result at different levels of significance for different outcomes. Students are...

### Health and climate change

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine. The Earth's climate is changing ever faster, and human activities play a role in speeding up this change.

The Earth’s climate is changing. In fact, it has always been changing. What is different now is the speed...

### Drugs *suitable for home teaching*

Published by the Wellcome Trust, the 'Big Picture' explores issues around biology and medicine.

While providing immense benefits, drugs are not the perfect solution. They only work on a proportion of patients, sometimes they harm us, and we're not very good at taking them as we should. For some diseases,...
