2. What are measuring tools?
are devices, gadgets or equipments used as aid in
finding such exact numerical values of a certain object.
These are usually made up of either synthetic or
natural materials.
Are calibrated with the standards of measurements to
provide precise and accurate results.
Mostly are used in several purposes while others are
only for a specific function.
3. Examples:
Rulers,
triangles,
protractors
and more.
4. What do they measure?
Length
Time
Mass
Temperature
Electric Current
Amount of Substance
Volume
Density
Light Intensity
5. Things to consider in using the
tools:
Accuracy – the state of being accurate (the result
obtained with respect to the given standard).
Precision – being precise (the result obtained from a
series of trials, the closeness of the average result with
respect to the given standard).
User’s capacity and familiarity – implied on both the
teacher as well as the learners readiness and the ease in
using the tools.
6. Standard of Measurement – this refers to the units that
are calibrated and set by an international governing
body. Today, the SI units (improved version of metric
system) and the English system (known also as Imperial
system) are used as standards for the equivalence of
measurements.
7. Functions
Aid the learners in attaining precise and accurate
results in measuring the objects which are related to
their topics.
Serve as motivator as well as a facilitator for the
students in their learning processes involving
measurements.
8. Advantages
Saves time and effort with respect to the topic to be
presented
Brings the students to the real situation much easier
yet provides enough fun
Helps the users to understand more about the
complex concepts
Very much accessible to most of the learners
9. Disadvantages
Some measuring tools require much time and effort
for them to yield the accurate and precise results.
Others maybe to large or to small to be used in
measuring objects.
Amount and the availability of some tools requires
considerable finances as well as the handling of these
tools often requires great caution.
10. Guidelines
Right tool for right object.
For much complex types of tools, teacher is advised to be
the only person to use and perform to avoid any accident.
Start always from simple tools then to the complex ones
later same with the degrees for measurement.
Both measuring tools and the objects to be measured should
be prepared and tested by teacher ahead the teaching time
for convenience as well as to prevent waste of time and
effort.
11. Criteria For Evaluation
Is/are the measuring tool/s needed for the discussion
available enough for the students to acquire?
Are there other substitute tools that can be used in
case the primary tool/s is/are not present and still
yield the same result required?
Is it the right tool to be used for the specific object?
Can both the teacher and the students able to
manipulate well the tools to be used?
12. Do measuring tools are really needed in the
discussion? Or is there any relevance of the use of
these devices with the lesson to be discussed?
And if there are measuring tools that need
considerable amount of money and effort, would the
use of these tools justify the rendered time and money
to acquire the said tools?
How’s the condition of the tools that are to be used?
