3. MATERIALS

3.1. Steel Pipe

3.2. Range Pole

3.3. Marker (chalk)

4. PROCEDURES

4.1. Determining Pace Factor

4.1.1. Select a straight level course on the ground and on both ends establish points A and B.

4.1.2. Set the range pole on point A and measure the distance to point B.

4.1.3. Walk over the course with gait starting with either heel or toe over point A and count the number of paces to reach point B. Record the number of paces as trial 1.

4.1.4. For the next trial, walk from B to A then from A to B again until 5 trials are completed and record the number of paces accordingly.

4.1.5. Determine the mean number of paces by dividing the sum of the number of paces performed on course AB by the number of trials.

4.1.6. To determine the pace factor, divide the taped length of course AB by the mean number of paces for AB.

4.2. Determining Horizontal Distance by Pacing

4.2.1. Establish the end points of another level course and name these as C and D.

4.2.2. Walk over the course from C to D and record the number of paces as first trial. Then walk from D to C and go back to D for the second and third trials respectively. Record the number of paces accordingly.

4.2.3. After the field data are recorded, determine the taped distance of the course CD for the relative precision.

4.2.4. Compute the mean number of paces by dividing the sum of the number of paces on course CD by the number of trials performed.

4.2.5. To obtain the paced distance, multiply the mean number of paces for CD by the computed pace factor

4.3. Determining Relative Precision

4.3.1. Determine the difference between the taped distance and the paced distance of course CD.

4.3.2. To determine the relative precision, divide the computed difference by the taped distance of CD and reduce the numerator to unity or 1.

7. PRESENTATION AND ANALYSIS

The fieldwork that was done and demonstrated by the group is called pacing. Pacing is reasonably an easy and quick method of measuring a distance in a field. It is the movement of an individual whether it is a single step or a series of steps wherein the length of the distance of the steps are recorded in order to compute for the pace factor. The materials used for the fieldwork are steel tape, range pole and chalk. To start the activity the group first plot a straight line measuring 25 meters using the steel tape and placing a range pole on both ends to mark points A and B. Each member conducted 5 trials, first they walk along the straight line in their normal pace and count the number of steps or paces until they reach the opposite point from where they started. For the data of very trial, it is recorded in the table 6-1 and then computed to get the average number of steps.

Another activity is also conducted by the group where each member had three trials of walking in their normal pace along a 32.95meter long straight line. Their steps was counted to get to the opposite point and recorded in table 6-2. It will determine the accuracy of the pace factor of each member through multiplying the number of steps to their pace factor. Based from the result it shows that the pace factor may be used to estimate the length of an area as long as every steps and pacing are consistent

In conclusion, an individual pacing may be able to determine the length of a certain area as long as the pace factor of his/her consistent pacing or walking is computed correctly, then the length of the area to be estimated should be close to its original length.

8. REMARKS AND RECOMMENDATIONS

Based on the examination and discovery of the researches for they suggest that even though the pacing can be used in approximation the length of an area but it is still necessary and better to used the right measuring tools and instruments to aim the right measurements. Pacing is beneficial if the right tools or instruments for measuring are not available. If pacing needs to be applied to measure the length of a certain area, it is important to make sure the pacing of the person applying the method is constant and should be calculate exactly to be able to determine at least the estimated measurements.
