### Transcript

• 1. MEASURING TOOLSBSEd II-ALourise Archie C.Subang
• 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?
• 13. QUERIES? FURTHER IDEAS? REACTIONS? Classmates and Teacher
• 14. THANK YOU FOR LISTENING!!!!God bless us all!!!
