The use of stethoscopes to determine heart rate was introduced to the students earlier in the week and at our last collaboration meeting, it was decided that we would include the use of these stethoscopes in the following PE lesson. As I was planning on having the students record their own heart rates and record these heart rates on a record sheet in the next PE class, we came up with a better plan which was to also have the students use stethoscopes as well.
The students (the patients) were responsible for recording their own rate (on neck or wrist), as well the doctor would simultaneously determine their heart rate as well using the stethoscope. The 6-second formula was used to keep it simple. For those who didn’t read my previous blogs about the 6-second formula, it is very easy. On my command ‘begin counting’, I use a stopwatch to count off 6 seconds. On my command ‘stop counting’, the students add a zero to the number of heart beats in 6 seconds (for example, 14 beats in 6 seconds would be 140 beats a minute). This determines their number of beats per minute which will be recorded.
As you can see on the record sheet above, there are 2 sections. One for ‘Tactile’ heart rate (heart rate determine by feeling pulse in wrist or on neck) and one section for ‘Auditory’ heart rate which is determined by the doctor using a stethoscope.
The students took part in 5 different activities, each having a go as patient (the one exercising) and as doctor (the one sitting and watching, ready to use stethoscope on patient to determine heart rate). The activities were as follows:
Cool Down (Light Exercise): Students, both doctor and patient, slowly walk around gym and talk about games they have played. They talk about what they have learned. They make their way back to their team area in order to determine and record cool down heart rate. The patient takes their own heart rate and records it. Doctor takes their heart rate as well and reports number of beats per minute back to the patient. Patient records this number as well under ‘Auditory’ column.
Please see video below of some snippets of the great times today!
The students were excellent as was their classroom teacher, John Rinker (http://johnrinker.edublogs.org/), who came along to class to help out and take part in the activities. Please view slide show below to see some examples of student assessment and some photos of the kids in action. A great day at NIS.
