Gradient rate of change
The images that teachers and students hold of rate have been investigated.2This study investigated the relationship between ratio and rate, and identified four levels of imagery with increasing levels of sophistication: 1. Ratio 2. Internalised ratio 3. Interiorised ratio 4. Rate The authors describe rate as 'a … See more The gradient can be defined using the generic straight line graph (fig 1). To determine the gradient of the straight line we need to choose … See more A very simple example (fig 2) will illustrate the technique. P and Q are chosen as two points at either end of the line shown. Their coordinates are (0,1) and (5,11) respectively, so we … See more Obtaining the wrong sign on the value of a gradient is a common mistake made by students. There are two ways of dealing with this. One is to recognise that the graph slopes the opposite way (fig 4). The other is to apply the … See more As is often the case, there are new levels of complexity once we start looking at real chemical examples. The Beer-Lambert law A =εcl predicts the absorbance A when light passes through a solution of concentration c … See more WebCovers all aspects of the new GCSE specification, including drawing tangents to estimate gradient of speed-time or displacement-time graphs, and estimating/calculating distance by area calculations.
