Problem(คำถาม) and Solution(วิธีแก้ปัญหา)

75 Problem Solution Speech Topics

Problem solution speech topics, 75 ideas and guidelines to help you selecting, defining and organizing your public speaking speech topics. Persuade your audience that there is a problem and that you have the solution. Convince them to agree with your solution and motivate them to change their opinions, policies or regulations. Before you choose one of the problem solution topics in my list of examples you have to know the elements you have to develop. These four elements for problem solutions speech topics are extracted from the very famous Monroe's Motivational Sequence for persuasive speeches:

1. Problem - State the problem or that some conditions are not quite optimal, and why it's important. Let them realize the scope and effects. Appeal to reason and to the needs and emotions of the audience to persuade them.

2. Solution - Advocate a solution for the problem and causes, or a plan to satisfact the needs.

3. Visualization - Visualize the practicality of your solution. Show how the solutions will improve the situation, show their effectiveness and practicality. Prove that the alternatives are impractical and cause more problems in order to overrule the objections against your solution.

4. Action - Convince them to agree, to change an existing policy or attitude, or move them to action in the way you propose in your problem solution speech topics.
How to Select Your Problem Solution Speech Topics
If you are invited as public speaker because of your personal knowlegde or experience, then find out what the problems, interests and needs of your audience are. Problem solution speech topics deal with questions, opinions or controversies of change or policy. However, there are public speaking situations in which you can answer questions of facts and values. For example if you are a keynote speaker:
-Are you the only keynote speaker or one of many?
-If you are not the only one: do you have to argue with another speaker about your solution?
-Has your audience heard you before?
- What is their impression of you or your organization?
-If you are developing a problem solution speech for educational purposes:
-What exactly are the rules of the assigment?
-How long will your talk last?

List Of 75+ Problem Solution Speech Topics

Now let's have a look at the list of 75+ problem solution speech topics below. Read the list of speech topics carefully and brainstorm a bit about possible causes, problems, effects and solutions. These questions may help you to brainstorm and develop a short list of possible problem solution speech topics:
-What do you like to talk about?
-How long will your talk last?
-What are your personal concerns and convictions?
-Which of the speech topics are you interested in or you do know something about?
-What are global, national, state, community or school related problems, issues or controversies, and causes, effects and solutions related to the text to speech?
-Is there a connection between some problem solution speech topics and any of your personal experiences, expertises or personal goals?
Be inspired, use your fantasy and come up with new problem solution speech topics.
LIST OF SPEECH TOPICS:

BUSINESS - Abusive Marketing, Bankruptcy, Corporate Whistleblowing, Foreign Import Concurrency, Job Opportunities, Unemployment, Subversive Advertising, Thwarted Career Goals, Unjustifiably Large Incomes, Work Environment
EDUCATION - Academic Pressure, Cheating, Dropouts, Competency Tests, Lack Of Educational Opportunities, Parent Education, Sexeducation In Schools
ENVIRONMENT PROBLEM SOLUTION SPEECH TOPICS - Acid Rain, Alternate Energy Sources, Climate Change
FOOD AND HEALTH - Abuse Of Patent Medicines, Dangers Of Food Additives, Dental Health, Depression, Fat In Low Price Food Products, Food Labeling, Health Care, Integration Of The Disabled, Problems Of The Mentally Ill, Survey Of Diets, Testtube Babies, Vegetarianism
GLOBAL AND POLITICS - Food Shortages, International Threats, Overpopulation, Subsidizing Farms, US And UN Relationship
LEGISLATIVE AND JUDICIAL - Crime And Punishment, Drunk Driving Accidents, Effects Of Prejudice, Gun Control, Hate Crimes, Illegal Immigration, Safety And Security, Taxing Of Church Property
SOCIAL PROBLEM SOLUTION SPEECH TOPICS - Airbags, Cigarette Advertising, Decreasing Car Accidents, Discrimination, Domestic Violence, Family Breakdowns, Forced Retirement, Gambling, Hobbies, Home, Internet Spam, Interpersonal Relationships, Loneliness, Minimum Wage Level, Peer Pressure, Reducing Neglect, Runaways, Self Esteem, Social Security, Teenage Runaways, Problems Of The Elderly, Problems Of The Family, Problems Of The Homeless, Problems Of The Hungry, Tobacco Use, Underage Drinking, Voting System
Problem Solution Speech Topics: What Is The Problem?
By now, you have a short list of candidate problem solution speech topics. Let's move forward and develop them further. Examine the dimensions of the problems or potential problems. Use this easy information checklist:
-What has been done till now or why not?
-How could the problems or obstacles be defined or described?
-What are the duration and costs?
-Will it become worse if nothing will be done?
-Is immediate action required?
If your listeners understand there's a need or problem, they are more willing to accept the solutions and recommendations in your problem solution speech topics. For instance think about the social, physical, health, happiness, security, concerns, value and needs in the audiences' community. Examine and make a speech preparation outline with the dimensions of the problems or potential problems in your problem solution speech topics.
-Have your audience or other people been affected by the problem and in what way?
-What could be your evidence, which facts and figures can prove the proper dimensions for them and that you're right?
-What information can help them to understand the problem?
What Is The Solution?

List all the various potential solutions and alternatives. Imagine the features, aspects and merits that might persuade the audience by researching illustrations, facts, figures, expert testimonies and examples. Do it step by step, in each problem solution speech topic:
-Select your best possible solution for the problem.
Demonstrate the workability of your plan by citing experts and refering to a successful implementation elsewhere in your problem solution speech topics.
-Recommendate procedures for implementing the solution.
-What are the effects, costs and required actions?
-Who should take action, and when and where?
-What else is necessary?

NOTES: If the audience is devided, not sure or unaware of the problem, then pay more attention to the urgency and the needs of your audience. If they know the problem exist, then pay more attention in your problem solution speech topics to the reasonablity and workability of your plan. In case you want to oppose to a change in policy, because another solution causes problems, then emphazise the limitations and the dislikes.
How to Outline Your Problem And Solution Speech Topics

These are the most used methods of developing and outlining problem solution speech topics:
* Problem Solution Method
Recommended if you have to argue that there is a social and current problem and you have convince the listeners that you have the best solution. Introduce and provide background information to show the problem. List the best and ideal conditions and situations. Show the options. Analize the proper criteria. And present your plan to solve the problem.
*Problem Cause Solution Method
Use this pattern for developing problem cause solution speech topics. Identify the problem and its causes. Analyze the causes and propose solutions to the causes.
* Problem Cause Effect Method
Use this method to outline the effects of a problem cause speech topic. Prove the connection between financial, political, social causes and their effects.
*Comparative Advantage MethodUse
this organizational pattern for so-called compare contrast problem solution speech topics. Recommended in case everyone knows of the problem and the different solutions and agrees that something has to be done. Compare the features and the differences of possible solutions and procedures. And explain why your solution is the most preferable one.

Passive Voice


Passive Voice

Patient + V. to be + V. 3 (+ by agent)


Active sentence
The dog bit John
ประธาน (agent) กริยา (Verb) กรรม (patient)

Passive sentence
John was bitten by the dog.
ประธาน (patient) กริยา (Verb to Be + V.3) ผู้ถูกกระทำ(agent)

วิธีการเปลี่ยนรูปประโยค active เป็น passive voice
1. หาประธาน กริยา และกรรมของแต่ละประโยค
ถ้าในประโยคนั้นไม่มีกรรม หรือคำกริยาเป็นกริยาชนิดที่ไม่ต้องการกรรม จะเปลี่ยนเป็น passive voice ไม่ได้ เช่น

Active: The postman brings letters.
Passive: Letters are bought by the policeman.
2. สลับที่กันระหว่างประธาน (agent) และกรรม (patient) ของประโยค active และ passive
- ประธานของประโยค active (agent) ให้ย้ายที่ไปไว้ท้ายประโยค passive โดยวางไว้หลัง by (by + agent)
- กรรมของประโยค active จะกลายเป็นประธานอยู่หน้าประโยค passive
หมายเหตุ: ถ้า agent เป็นสรรพนาม (pronoun) ให้ใช้สรรพนามรูปกรรม (me, you, them, us, him, her, it) ในบางประโยค by + agent อาจละไว้ได้ ถ้าไม่จำเป็นต่อความหมายของประโยค เช่น

This bridge was built several years ago.
3. คำกริยาในประโยค active ให้เปลี่ยนเป็น passive โดย
- เติม verb to be ไว้ข้างหน้าคำกริยา และผัน verb to be นั้นตาม tense ของประโยคเดิม และผันตามประธานที่อยู่ข้างหน้า
- เปลี่ยนคำกริยาหลักในประโยคเดิมให้อยู่ในรูปกริยาช่องที่ 3 (past participle)
4. สำหรับประโยคที่มีกรรม 2 ตัว (direct and indirect objects) ประโยค passive สามารถเขียนได้ 2 แบบ เช่นเดียวกับประโยค active เช่น
Active: Sam gave me a present.
Sam gave a present to me.
Present: I was given a present by Sam.
A present was given to me by Sam.
5. ในกรณีที่ประธานในประโยค active เป็น they, people, someone, etc.
Active Present
They clean the streets every day. The streets are cleaned every day.

Predicting harvest labour allocation in bell pepper production
Tijskens L.M.M.; Lin W.C. and Schouten R.E.5th International Postharvest Symposium . Volume of Abstract . Verona, Italy 6-11 June 20042004
บทคัดย่อ
In the production of bell peppers large fluctuations exist in number of fruits ready to pick. That makes it very difficult for growers to allocate sufficient labour force at a certain time in production.Both allocating too many and too few pickers will have financial consequences for the grower. The development of bell pepper ripening has been followed by colour imaging in the greenhouse. A commercial digital camera was used to record in time the development of colour for two cultivars (4 samplings in two seasons). The images were analysed by image processing to obtain the R, G and B values. The time to harvest was recorded for the same fruits. A model was developed to describe the colour development, expressed as R/G ratio, and to predict the optimal harvest date of the fruits.
By using a commercial digital camera under non-standardised conditions large variations will be introduced. Using a ratio of colour aspects reduces this variation. For o­ne cultivar, repeated data were recorded in time for the same individuals. Non linear regression analysis of these data resulted in an explained part of 95%
Assuming for the time being that the rate constant would be applicable to all cultivars and all growing season, the anticipated harvest time for the other 6 data sets was calculated, using these estimated parameter values. These data sets contained o­nly o­ne or a very limited number of measurements in time for individual fruits, and could therefore not be used to calibrate the exponential model. The difference between measured and estimated harvest time was 1 week or less for more than 80% of the measured individuals. In view of the assumptions used and the frequency of harvest time determination (1 week), this was rated as satisfactory.
Research is going o­n to validate the viewpoints.

Time Clauses

Time Clauses
Using Before, After, While and When


We use these words (before, after, while and when) to introduce time clauses to tell when something happens.
Rudy washed the floor before he watched the soccer match.
Rudy washed the floor after the soccer match.
Rudy washed the floor when the soccer match ended.
Rudy washed the floor while he was watching the soccer match.

In all of these cases, Rudy washed the floor. However, we have to look at the time clauses to see when the floor was washed.
Time clauses:
before he watched the soccer match
after the soccer match
when the soccer match ended
while he was watching the soccer match

In all of these examples, the main (independent) clause is "Rudy washed the floor". The time clause simply states the relationship of other actions (watching the soccer match) to the activity in the main clause.
Let's analyze the time sequence--with another example.
The phone rang after we ate dinner. (First we ate our meal, and then the phone rang.)
The phone rang before we ate dinner. (First the phone rang, and then we ate.)
The phone rang when we started dinner. Also: The phone rang as we ate dinner. (We started to eat and the phone rang at the same time.)
The phone rang while we were eating dinner. Also: The phone rang as we were eating dinner. (This is the same as above, but with the progressive tense [-ing]).

The Grammar

Independent clause Dependent clause
= The phone rang = before we ate dinner.

The phone rang is an independent clause. It can stand alone grammatically.
before we ate dinner is a dependent clause. It needs an independent clause to be a complete sentence. It is a sentence fragment when it is used alone.

Punctuation
-The phone rang before we ate dinner.
-Before we ate dinner, the phone rang.
When the independent clause comes first in the sentence, no comma is needed.
When the dependent clause comes first in the sentence, the clauses are separated by a comma.

Different verb tenses
Look at these verb tenses:
*two past tense events
-It started to rain before I got home.
-Jaime had a drink before he played tennis.
*modal auxiliary and present tense
-I have to get home before it starts of rain.
-Jaime has to have a drink before he plays tennis.
*two past tense events
-Henry went to the movie after he had dinner
-Prof. Simon gave a test after the spring break ended.

*modal auxiliary and present tense
-Henry may go to the movie after he has dinner.
-Secretary Simon ought to negotiate with the rebels before the situation gets out of hand.

*an on-going event interrupted by a single event in the past
-Myra was reading a book when the phone rang.
*past tense cause and effect
-Myra had to get up when the phone rang.
*two past tense events
-Ben asked for a ride when Myra answered the phone.
*two future events
-Myra will leave to pick up Ben when she hangs up.
*two past tense continuous activities
-I was listening carefully while the manager was explaining the problem.
*one past tense continuous event interrupted by single action

The Spark: The Grandest Train in the World
By Dave SikulaWed, December 3, 2008, 12:01 am PST
NYC Hudson at the 1939 World's FairIn a world where even the most remote corners of the globe can be reached in a matter of hours, it's hard remember a time when a train going 60 miles an hour from New York to Chicago was considered the ne plus ultra of travel. But that's the story of the 20th Century Limited, the luxury train that ended its final journey on this day in 1967.
