The authors would like to acknowledge Dr. Judy Greene, Director, Center for Teaching Effectiveness, University of Delaware, Newark DE 19717 for her assistance in the preparation of this manual. This project was supported, in part, by an EPA Region III Environmental Education Grant, "Increasing effectiveness of homeowner pesticide safety training using active learning technique."
HOW TO USE THIS MANUAL
This manual is written for extension agents and specialists who work with Master Gardeners. It is meant to be used in conjunction with the Extension Master Gardeners Training Manual of the same title. These manuals are designed to teach the educational technique of active learning and use the lesson "Be Safe With Pesticides! Read the Label" as an illustration. The best way to teach Active Learning is to use it yourself in the classroom. Throughout the manual are examples of Active Learning strategies. According to Bonwell and Eison (1991), a person's attention span in the class room is about 10 -15 minutes. As you deliver this lesson, you will be changing your teaching technique often.

BE SAFE WITH PESTICIDES! READ THE LABEL
Thank the Master Gardeners for attending this program. Tell them that you will be presenting the lesson "Be Safe With Pesticides! Read the Label" as if you were a member of the Master Gardener's Speakers Bureau. Ask them to play the role of the audience for your lesson. Tell the Master Gardeners that as they participate, they will learn how to deliver this lesson.
In (Speakers comments are in quotation marks)
"How many of you have applied pesticides at home?" Listen to the answers and point out that even toilet bowl cleaner is a pesticide.
"Anything that kills or repels a pest is a pesticide." Name some pests and their pesticides: insects (insecticides), weeds (herbicides), plant pathogens (fungicides), snails & slugs (molluscides), trash fish in a sporting lake (piscicides), birds (avicides), nematodes (nematicides). (Do not say, "Herbicides and pesticides." Herbicides ARE pesticides.)
Put members of the audience into pairs. Ask them to, "Tell your partner what you grow in your garden." Allow only 2-3 minutes, then begin the lesson. Use a kitchen timer or turn the lights on/off when time is up.
Outline the program on the flip chart or overhead
"Today we will:
Have a problem solving exercise
Review parts of the pesticide label
Look at a take home activity and do an
Evaluation of the program."
"Here is a problem for you to solve: You are working in your yard and you see that your favorite azalea has bugs all over it. You figure that you need to apply a pesticide. You grab your car keys & jacket and head over to the garden store. You pull up in the parking lot, go inside. You note that the clerk is busy and has a line waiting to talk to him. So you're on your own. You stand in front of the shelves of pesticides. You need to decide which pesticide to buy. How do you do this? What questions do you ask yourself to decide which pesticide to buy? What do you need to know before you can make a pesticide application?Write one question on the index cards & pass to front."
Read some of the index cards, then list the questions on the overhead or flip chart. It is easier to have a second person list the questions while you sort the cards and read aloud the ones you want listed.
Will it kill the bug?
Can I use it on azalea?
Is it harmful to kids & pets?
Will it hurt the environment?
Keep saying that the questions are very good. Support the efforts of the attendees.
Continue with the lesson. Hold up one of the make-believe pesticide jugs: "So, we decide which pesticide to buy, get back in the car, and drive home. Now you are home with your pesticide. You jump out of the car, take the pesticide container over to the azalea. But hold everything! Wait a minute! You need to decide how to apply this pesticide. What questions do you ask yourself to decide how to apply this pesticide ? What do you need to know before you can make a pesticide application?"
"Write your questions on the index cards & pass to front."
Read some of the index cards, then list on overhead or flip chart.
Do I have the right personal protective equipment (PPE)?
How much do I apply?
How do I mix it?
When do I apply it?
Where do I apply it?
How do I apply it?
When can I let kids & pets back in the area?
Keep saying that the questions are very good. Support the efforts of the attendees.
Continue with the lesson. Hold up one of the make-believe pesticide jugs: "Would it surprise you if I said that you can find all the answers to these questions on the pesticide label?"
"Let's set our lists of questions aside for a minute and look at the handout, 'The ABC's of a Pesticide Label." Put the flip chart to the side or turn off the light on the overhead projector. Pass out the handout.
Give the members
of the audience time to look at their handout while you say, "Everything
you need to know to be safe with pesticides is on the label. Read the label
Before you buy the product
before you store it
before you mix & load
before you apply, and again
before you dispose of the empty container."
"This handout lists every part of the label. I'm going to emphasize certain sections:"
Parts of the label
"The formulation tells you what the pesticide looks like when it pours out of the jug. You must match the formulation with your application equipment. If the formulation is a granule, you need to use a drop spreader. If the formulation is a liquid, you need a pump-up sprayer, hose end sprayer or other liquid sprayer. Some of your pesticides will be 'ready to use' so you won't need equipment."
"You must also match the formulation with the pest problem. If you have a leaf-eating insect, a granular formulation won't help. The granules won't stick to the leaves. You need to use a liquid or a dust that will stick to the leaves. If you are treating broadleaf weeds in the lawn, you can use a granular formulation."
D. Type of pesticide:
insecticide, herbicide, fungicide, nematacide, rodenticide, moluscicide,
"You must also match the type of pesticide to the pest. Using an herbicide for our bug on azalea won't do much good."
H. EPA numbers.
"These numbers tell you that the product is legal. Before a company can begin to sell a pesticide they must submit results of laboratory experiments to EPA. Once EPA has reviewed the documents, they register (not approve) the pesticide and give it a number. If you do not see an EPA number on a product that makes pesticidal claims (kills or repels pests), that product is illegal."
I. Signal word
"There are 3 signal words. These words tell you how toxic the product is to you the applicator, not to the pest:
Danger, the most toxic
Warning, less toxicity
Caution, lowest toxicity."
"Here is a problem for you: You're trying to decide which pesticide to buy. You pick out 2 pesticides. Both say they will do the job. One has a signal word 'Caution.' (Hold up one of the make-believe pesticide jugs) The other is 'Danger.' (Hold up the other make-believe pesticide jug) Which one should you use?"
Take a "Thumbs up/Thumbs down" vote & then explain why use you should use the pesticide with a caution signal word.
Route of entry
and Specific action statements
"This statement helps you pick PPE. There are 4 routes of entry: dermal, eyes, respiratory, ingestion. What are the sites of greatest absorption? (Answers: Groin, face, forehead.)
If the label says, 'fatal if swallowed,' what would you do? (Answers: don't eat, smoke or drink while handling. Use a face shield)
If the label says, 'don't breath vapors and mists,' what would you do? (Answers: use a respirator, stay upwind)
If the label says, 'don't get on skin,' what would you do? (Answers: Use chemically resistant gloves, fore arm protectors, aprons, tyvek suits)
If the label says, 'keep out of eyes,' what would you do? (Answers: wear goggles or face shield)."
the forearms get 13% of contamination from pesticide exposure. The hands
get 85%. This adds up to 98% of exposure that could be completely avoided
by wearing rubber gloves and forearm protection."
"The very minimum
PPE is long legged pants, long sleeved shirt, non absorbent hat, gloves
"What happens if
you wear a baseball cap or leather work boots?" (Answer: They will absorb
pesticides and continue to contaminate you every time you wear that item.)
K. User safety recommendations
"PPE means Personal Protective Equipment. Look for this section on the label, but also use the signal word, route of entry and specific action statements to help you choose PPE. The minimum PPE is long-sleeved shirt and long-legged pants."
"Sometimes even the right PPE is not enough. Don't wipe your forehead, eat, smoke, drink while applying pesticides. Wash hands before toileting."
"When mix/loading, the forearms get 13% of contamination from pesticide exposure. The hands get 85%. This adds up to 98% of exposure that could be completely avoided by wearing rubber gloves and forearm protection."
"The very minimum PPE is long legged pants, long sleeved shirt, non absorbent hat, gloves and footwear."
"What happens if you wear a baseball cap or leather work boots?" (Answer: They will absorb pesticides and continue to contaminate you every time you wear that item.)
K. User safety recommendations
L. First Aid
"You need to know first aid procedures before you have an accident. Keep a copy of the label on a clip board in the storage/ mixing/ loading area."
M. Environmental hazards
"Pesticides may be hazardous to water, pollinating insects, birds, other wildlife. Make sure you plan ahead & scout the area."
N. Directions for use.
"You will use this section a lot. It explains when -- what time of year, what time of day -- and how you will make the application."
P. Storage and Disposal:
"Always store pesticides in a locked, cool, dry, well ventilated, facility. The best facility has a sealed concrete floor and stainless steel shelves."
"For disposal of unwanted pesticides, the label will probably tell you to wrap the container in newspaper and deposit in the trash. Your county may have a pesticide collection program. Check with your county extension agent, state environmental protection agency, or state department of agriculture for details."
"For disposal of empty containers, triple rinse and take to your recycle site or sanitary land fill."
R. Mixing directions:
"This section tells you how to mix - what solvents to use & how much."
"This is a very important section. Site - you can apply a pesticide only to a site listed on the label. Here is a quick quiz:
You have a problem
with downy mildew in your roses. Here is Zappo. (Hold up one of the make
believe pesticide jugs) It says it kills downy mildew pretty well. It lists
mums, azalea, and ferns on the label. Can you use on roses?"
Take a "Thumbs up/Thumbs down" vote & then explain that the site, roses, must be on the label.
"Pest - if the product is effective against your particular pest, it will be listed on the label. You will also find rates and application equipment here."
Y & Z Chemical/ physical
"Make sure there are no sparks or fire hazards. Make sure the pesticide does not get too hot or too cold."
to the flip chart
After reviewing "The ABC's of a Pesticide Label," return to the flip chart or overhead projector list. Ask the audience to help you code each item on the list using "The ABC's of a Pesticide Label." For example, if the first question on the list is "Will it kill the bug?", code this question "S" for Approved Uses. If the second question is "Can I use it on azalea?", code that question "S" also. If another question is "Do I have the right personal protective equipment (PPE)?", code that question "J". The question "How much do I apply?", would be coded "N".
Now review the coded list. Make another list of letters that the audience did not use. They often forget C - formulation. Remind them to check the forgotten parts of the label the next time they buy and use a pesticide.
Wrap up your presentation with, "We've learned a lot about the different parts of the pesticide label today and how we can use the label to help us make decisions and practice safety. Now I will pass out the take home handout and the evaluation that were on our agenda."
Review the take home activity, "Making Pesticide Applicator Decisions from the Label."
See the University of Delaware web page: http://www.udel.edu/pesticide/publications/safeprac.htm for directions on conducting the evaluation. Go to Method II: Pesticide Applicator Training Evaluation Form. Print the evaluation form "Put Safety into Practice!" as a 3-part no-carbon-required (NCR) form. Pass out the evaluation form. Ask the audience to write 3 pesticide safety practices that they want to start using at home. Each person should keep the bottom copy of their 3-part NCR and give you the top two copies. Tell them that you will send the form back to them after they have used pesticides for a few months. Tell them that you will ask them to check those practices that they have used at least once and those that they have adopted as routine.
Breaks are an important part of the learning process. They give the audience time to digest the material and discuss it with each other breaks also serve as a transition to the next topic.
The Master Gardeners in your audience have
just experienced active learning. But they may not know it!
Say to them, "Remember when I asked you, 'What questions do you ask yourself
to decide which pesticide to buy? What do you need to know before
you can make a pesticide application?' What was going through your
mind when I asked you that?
Typical answers are: "I pictured myself in the garden store," "I tried to answer the question," "I thought about my front yard," "I had to think," or "I remembered working in the yard last weekend."
Now announce to the Master Gardeners, "Welcome to active learning!" Continue with, "You have just experienced active learning. In the second half of our program, we are going to talk about this educational technique. We will develop a definition of active learning and find out about why it is better way to teach. We will learn how to make a classroom comfortable. Then we will review a list of active learning techniques that you can use as a member of the Master Gardener's Speakers Bureau. By the time we are done, you will be ready to do the same lesson that I just did in the first half of our program."
Put this agenda on the overhead or
Define active learning
Barriers to using active learning
Making the classroom comfortable
Techniques of active learning
Now continue with the lesson. Speakers comments are in quotation marks.
"Active learning is best described by contrasting it to the traditional technique of lecture. In a lecture, the instructor stands in front of the class and "gives" information. Members of the audience may take the information or they may not. Lectures are sometimes considered to be "passive learning." However, educators know that learning can never be a passive activity. Active learning is an educational technique that de-emphasizes transmitting facts. Students learn by doing activities, thinking about the subject and relating it to their everyday life."
Review the following characteristics of active learning:
What does active learning look like?
* Members of the audience are involved in more than passive listening.
* Members of the audience are engaged in activities, such as reading, discussing, and writing.
* Less emphasis is placed on information transmission
* More emphasis is placed on developing skills.
* More emphasis is placed on exploration of attitudes and values.
* Individuals receive immediate feedback from the speaker.
* Members of the audience are involved in higher order thinking, such as analysis, synthesis, and evaluation
* Active learning involves people in doing things and thinking about the things they are doing!
B. WHY DOESN'T
EVERYONE USE ACTIVE LEARNING?
"Active learning is an exciting way to teach a class. But some speakers are reluctant to try new techniques." Ask the Master Gardeners to write on a slip of paper one reason why they might be concerned about using active learning in the classroom. You don't need to collect the papers. Give them 90 seconds to do this activity. Use a kitchen timer to "call time."
"Did any one say, "I won't be able to cover as much material."? "Studies show that 8 weeks after a traditional lecture, students retain only 25% of the material. With active learning, however, individuals retain 50% of the material. Yes, it is true that it takes more time to teach the same amount of material using active learning as it does to teach that material through lecture. But, if the speaker uses active learning and covers only 50% of the subject content, students will retain 25% of the subject - the same amount as with lecture (.5 X .5 = .25). If the speaker covers even slightly more than 50% of the subject, then more than 25% of the subject will be retained."
Did anyone say, "It takes preparation."? "Well, each new lesson requires preparation time whether it is traditional lecture or active learning. But, once a speaker tries active learning, the techniques become second nature."
How about, "My classes are too large to use active learning."? "There are successful techniques for working with classes of hundreds. The class can be divided into smaller groups with facilitators."
Did anyone say, "There aren't enough materials or equipment to use active learning."? "Today there are many resources available for the speaker who wants to use active learning. This lesson and the active learning manual you'll get at the end are good examples!"
How about the objections, "People resist any form of teaching that is different from lecture. They won't participate. They want to just sit there."? "Experience does not show this to be true, especially with the adult learner. People appreciate being treated like intelligent partners in the learning process. Didn't you like the label lesson better than a lecture?"
And my last one, did anyone say, "I'll loose control over the class."? "After group discussions, there are ways to get the audience's attention. I just used a kitchen timer. You can also turn the room lights on and off."
Ask if anyone wrote a different reason for not using active learning and help the group find a way around that problem.
Now distribute the Master Gardeners Training Manuals and the handout ACTIVE LEARNING: YOU CAN DO IT! Point out that most of what you have covered is listed here for them, as well as the lesson plan, "Be safe with pesticides! Read the label." Continue the lesson with Part C.
C. MAKING A CLASSROOM
"Active learning is a very personal approach to teaching and quite different from formal lecture. The speaker dialogues with the audience! It is important to create a comfortable learning environment when using active learning."
Review the following list:

1. Ask questions
But remember to wait for the answers.
2. Pause procedure
Take 2 minutes and write on an index card:
A. "What was the most important point from the last presentation, demonstration, video or slide show?"
B. "What didn't you understand about the last presentation?" (You will want to collect these cards.)
C. "Write an test question based on the last presentation."
Make a statement, such as "Your pesticide storage facility should be locked."
Ask who votes "yes", who votes "no." Or ask for a "thumbs up" vote if in agreement;
"thumbs down" if against. No one can see how their neighbor is responding --
the question is ungraded and it only takes a second to do.
4. Ungraded quizzes
Pass out short quizzes. Review the answers. Do not collect the quizzes - let the audience take them
A. Ask the audience to take notes for a short time.
Then ask them to tell the person next to them how the information from the last presentation
will help them in their garden.
B. Put members of the audience in pairs. Assign roles to each -
one person is a Master Gardener and the other the President of the Garden Club.
Ask them to, "Tell the Garden Club President how gardeners can protect the
environment from pesticide exposure."
Present a problem to the group. Ask for suggestions to solve the problem.
Example: "What questions do you ask yourself before you can make a pesticide application?"
Members of the audience can write their answers on index cards.
A. Show a "right" pesticide storage facility and a "wrong" one.
Ask the audience to contrast and compare the 2 rooms.
B. Show PPE & pass around room. Dress a gardener for a specific job.
8. Multi question worksheet
An example is found in this manual: "Making pesticide application decisions from the label."
Distribute copies of a pesticide label to the audience. Have members of the audience
break into small groups and complete the worksheet in their group.
Ask the audience fill in the worksheet, ACTIVE LEARNING: YOU CAN DO IT! Depending on the time, you can have them work on this in class or later at home. Wrap up the lesson by reviewing what the Master Gardeners have learned about active learning. Ask them, "What is one fact about active learning that you remember." Add more facts of your own to complete the lesson. Now your Master Gardeners are ready to use the lesson plan "Be safe with pesticides! Read the label."
