How do you evaluate the effectiveness of a lesson plan?
How do you know if your lesson plan was effective?
- Register yourself. It's amazing how much we see when we review a video of ourselves delivering a lesson plan.
- Ask a trusted partner to watch you.
- Ask a trusted colleague to read your lesson plan to you.
- Take notes during class.
- Check test scores and homework.

How can we improve the teaching-learning process through assessment?
Through frequent assessment and feedback, effective teachers regularly assess what they are doing in the classroom and whether their students are actually learning… Are students learning what you are teaching?
- Ask questions during class.
- Ask students their questions.
- Give frequent, short assignments or quizzes in class.
How do you evaluate an activity?
The easiest way to evaluate a meeting or activity is to distribute a form at the beginning of the session and remind participants to compete and return it before they leave. Make sure you ask no more than 6 questions. Make sure people know they are not expected to put their name on the forms.
Why is it important to evaluate activities?
Assessment of learning. All learning activities must be assessed. Evaluation allows you to check whether the required learning has taken place, that the learning methods used were appropriate and to help you improve future activities and programmes.
Why is it important to assess learning?
An important reason for assessing student learning is to find out how well students are learning what we say we are teaching: how well they are achieving the learning outcomes we have for them. Continuous assessment of student learning allows us to participate in the continuous improvement of the quality of our programs.
What problems can arise in supporting learning activities?
The type of problems that can occur when supporting a learning activity is that the student is not motivated or can't be bothered to do the work that needs to be done or they may have an attention span low and hard to concentrate on one thing at a time, etc.
What is M&E in accounting?
An analysis of your meals and entertainment (M&E) expenses can help ensure you're getting the most out of your business expense deductions. An assessment of M&E expenses can reduce your taxable income. The IRS now allows statistical sampling to determine adjustments to M&E expenses in Revenue Procedure 2011-42.
What does indicator mean?
An indicator is a measure or value that gives you an idea of what something is like. vital economic indicators such as inflation, growth and the trade gap. Synonyms: sign, mark, measure, guide More synonyms for indicator.
What are the types of indicators?
Types of indicators
What is a good property of an indicator?
A good property of an acid-base indicator would be an abrupt change in color over a specific pH range. Acid-base indicators (also known as pH indicators) are substances that change color with pH. They are usually weak acids or bases, which when dissolved in water dissociate slightly and form ions.
How do you know which indicator to use?
When selecting an indicator for acid-base titrations, choose an indicator whose pH range is within the pH change of the reaction. For example, in the titration of a strong acid with a strong base, the pH changes rapidly from 3 to 11.
What is the purpose of the indicator?
The usual application of the indicators is the detection of the endpoints of the degrees. The color of an indicator changes when the acidity or oxidizing strength of the solution, or the concentration of a certain chemical species, reaches a critical range of values.
Why is phenolphthalein the best indicator?
A strong acid-strong base titration is performed using a phenolphthalein indicator. Phenolphthalein is chosen because it changes color in a pH range between 8.3 and 10. It will appear pink in basic solutions and clear in acidic solutions.
Why do acid-base indicators change color?
The color change of a pH indicator is caused by the dissociation of the H+ ion from the indicator itself. Dissociation of the weak acid indicator causes the solution to change color.
What are the limits of the universal indicator?
Universal indicator Covers a pH range from less than 3 (red) to more than 11 (violet). Intermediate colors include orange/yellow (pH 3 to 6), green (pH 7 or neutral), and blue (pH 8 to 11).
What do you say when the indicator changes color?
pH indicator. A pH indicator is a substance that changes color in response to a chemical change. A drop of indicator solution is added to the titration at the beginning; when the color changes, the end point has been reached, this is an approximation of the equivalence point.
Do indicators change the color of acids?
When a universal indicator is added to a solution, the color change can indicate the approximate pH of the solution. Acids cause the universal indicator solution to change from green to red. The bases cause the universal indicator to change from green to purple.
What color is the universal indicator when the solution is neutral?
