John A. Van De Walle states that “to measure means that the attribute being measured is “filled” or “covered” or “matched” with a unit of measure with the same attribute.”
What is John Walle trying to say in the above sentence and does his explanation work equally well for length, area, weight, volume, and time?
In the given sentence, John A. Van De Walle is explaining the concept of measurement. He suggests that to measure something, we need to use a unit of measure that possesses the same attribute as the thing being measured. This means that the unit should be able to "fill," "cover," or "match" the attribute we are trying to measure.
Now, let's consider whether his explanation works equally well for length, area, weight, volume, and time:
1. Length: For length, we commonly use units such as meters or feet. We can see that these units can adequately fill, cover, or match the attribute of length, so the explanation applies well.
2. Area: Area refers to the measure of the surface covered by a two-dimensional shape. In this case, we measure square units, such as square meters or square feet. These units can also fill or cover the attribute of area, so the explanation applies.
3. Weight: Weight represents the measure of the force exerted on an object due to gravity. We use units such as grams or pounds to measure weight. While these units may not necessarily "fill" or "cover" the attribute of weight, they do allow us to match or compare weights accurately. So, the explanation works to a certain extent for weight.
4. Volume: Volume is the measure of how much space an object occupies. Units like cubic meters or cubic feet are used for measuring volume. These units can both fill and match the attribute of volume, so the explanation applies well.
5. Time: Time is typically measured in units like seconds, minutes, or hours. While these units may not directly "fill" or "cover" the attribute of time, they do allow us to compare and mark intervals of time effectively. Hence, the explanation works reasonably well for time.
In conclusion, John A. Van De Walle's explanation regarding measurement holds true for length, area, volume, and time. However, it may not be a perfect fit for weight, although the concept of matching or comparing weights with a suitable unit of measure is still applicable.
