Data logging

Data logging is an ICT medium that can be used to enhance the delivery of the curriculum. 


For example in one of our science sessions at university, we used data loggers to measure and record the temperature of water with ice cubes and salt to see the effect of salt on temperature. 

Data logging can be useful in science practical work as it: 

• Measures physical properties such as light, heat, sound and acidity. 

• Is a speedy and easy method of data capture 

 Provides an immediate link between the investigation and the result. Pairs real time events with their symbolic representation

• Provides time for pupils to observe and think about the experiment, rather than spending all their time recording data 

• Enables children to discuss the different aspects of a graph (e.g. gradient)

Bee-bots

During my GPP, I did not use bee-bots as I felt that they were too childish for my year 5 class. For my final placement, I will be teaching year 1 and I am looking forward to use this opportunity to incorporate bee-bots into my lessons.

BareFoot Computing has a lesson plan for an introduction to programming using bee-bots that I might try to incorporate in my maths lessons.

The lesson feeds into computing and maths in the following ways:

computing
- algorithms - understand how programs execute by following precise and unambiguous instructions

maths
- geometry: describe position and direction 
- fractions: understand whole, half, quarter and three-quarter turns 


The lesson: 


Pupils create sequences of instructions to enable the Bee-Bot to navigate a route tracing out the shape of numeral e.g. 3.


 The children can also try to record their instructions using simple drawings of the commands before executing the commands.  



The task is more difficult than it sounds and the initial algorithm that the students come up with may not do anything close to what they'd like the bee-bot to do.

For example, for the numeral 2, children may start with the following: 


This gives an opportunity to talk about turns (half turns). Scaffolding should eventually help students understand that an appropriate algorithm would look like this:


The activity will allow students to learn about programming, debugging and algorithms.
