research methods in psychology


Today's educators are bombarded with information from all sides about the latest and greatest research-based instructional techniques in teaching. With all these crazes about instructional methods and the confusion about which one really works and which one is a dud, no wonder our teachers are so exhausted! As charming and inspirational as all these latest claims and success stories seem to be, educators need to be careful when choosing and implementing a new or old "miracle" instruction method. There are things a teacher needs to do before making any big changes to their curriculum and instruction.

First things first, what supporting evidence is there? Educators need to use their resources wisely and take all initial information with skepticism. Before actually outright backing the "amazing" new research supporting a particular method, whether it be Indirect Instruction, Cooperative learning, etc..., educators must do their research. Talk to colleagues, look the strategy up online, check out education magazines and journals, and any other resource material available. Find out what evidence there is out there to support the research-based strategy. Furthermore, make sure the sources you are calling upon for information are reliable. Reliable sources offer reliable evidence, so seek out unbiased, professional resources. Weigh pros and cons, consistencies and inconsistencies, before making a decision on the strategy at hand.

After thorough research has been done, the next important question is: "How should the research-based program be implemented?" And "What methods does the research show to be most advantageous?" These questions' answers would most probably appear in your research since it was suppose to be incredibly thorough. If not, you'll want to look it up. Many teachers forget this step, and as Grassen states in the article "What Does It Mean To Be a Research-Based Profession" teachers simply aren't properly implementing research-based strategies are thus losing out on potential benefits of the programs. "Cooperative learning was designed to complement teacher-directed instruction by providing further opportunity for students to work together using what they have learned. In most schools today, cooperative learning is used to replace teacher-directed instruction and students are expected to construct their own knowledge working in groups." (N.d). Clearly, teachers need to put a great deal of thought into this step as improper implementation of the program can have catastrophic consequences on learners.

Read up on each research-based method, decide what sorts of lessons would benefit from their use, and which wouldn't. Talk to colleagues about what methods they use in the classroom, why, and how they implement them. Most of all, be aware of comparisons being drawn between different research-based strategies. Look for comparative studies as opposed to non-comparative studies. Comparative studies are more likely to give you accuracy in research. Educators need to look at the whole picture. How is class A using strategy A performing compared to class B using strategy B? How do these same classes perform after trading strategies? How is school A using strategy A performing compared to school B using strategy B? And so on...

Lastly, before implementing any research-based strategy, an educator should ask themselves "Am I biased?" Be sure to be honest with yourself. Try to go into deliberation with an open and unbiased mind. Take into account all reliable sources whether they are in-line with your initial beliefs or opinions on the strategy or not. Remain unbiased until the end. Your openness and willingness to learn can determine the accuracy of your research.

There are a great many research-based programs out there and being implemented everyday. Many of them just don't have the proper supporting research for an educator, especially a new and inexperienced one, to simply throw their weight behind. Don't ask your students to do homework without doing your own. Research your methods before putting them into practice. Find out what's behind them, what's supporting them, and how they should be used to the biggest advantage in the classroom. Without such information your newest instructional plan could be a huge failure. Don't follow fads and trends, look for rock solid evidence and implementation methods before making that big leap of bringing it into your classroom.

Few people would climb a mountain blindfolded. Yet company executives routinely pursue markets with blinders on-ignorant of market characteristics, the competition, and barriers to entry. Good ideas and good products aren't enough; a variety of factors can prevent first-class concepts from becoming profitable businesses. Opportunities need to be carefully investigated through objective market research. Investing in research can both save a business from making costly mistakes and increase its long-term profitability.



It's a common misconception that only large companies can afford market research. Just the opposite is true; small companies cannot afford not to invest in research. When resources are limited, mistakes are more damaging. Many small businesses fail because their owners don't do their homework-before starting the business and during the first crucial months. By performing a comprehensive market investigation-on their own or by enlisting the services of professional researchers-business owners can avoid pitfalls, increase revenues, and differentiate themselves from their competition.



Types of Market Research



Customer satisfaction is probably the most common form of market research but other kinds of research are equally important. The main categories are:• Competitor analysis - identifies who it is, pinpoints the strengths and weaknesses of other firms in the same market, shows where they are having success, and what they plan to do in the future. The objective is to stay a step ahead by taking advantage of their weaknesses, or at least keep up with them.• Market opportunity assessment - size, growth rate, trends, barriers to entry.• Product analysis - features, price points; determined by talking to potential customers to assess their desires before the product is introduced.



Research can be primary or secondary and quantitative or qualitative. A business needs primary research-which involves direct contact with sources of information-if it is trying to determine very specific, detailed information or is dealing with a technology, product, or service so new that there is a very limited existing body of literature. Customer satisfaction also requires primary research.



Secondary research involves the review of a body of existing literature about a topic. It is most suitable when a company wants a general overview of a broad topic, analyst opinions, and high-level quantitative information of an existing market.



Primary research is usually more expensive than secondary. Costs vary, depending on:• Sample size• How the survey will be administered - by mail, by telephone, online, focus groups• Whether just raw survey results or analysis and recommendations are desired



If resources are limited, a company can do secondary research in-house, provided in-house staff knows what resources are available, where to access the information, and how to interpret it. The Internet makes secondary research much easier and less expensive, because so many agencies have made information available for free. For example, government agencies worldwide furnish a wealth of quantitative information. Company Websites offer much valuable information, such as press releases, annual reports and financial filings, job openings, and product data sheets.



IT analysts and management consulting firms often make a limited number of reports and white papers available for free. Some companies also furnish free white papers, but these seldom are objective assessments.



Syndicated research reports are also available. These reports consist of long-term market forecasts, often segmented by geographical regions or vertical markets. Many businesses rely heavily on quantitative market forecasts to determine whether it makes sense for them to enter a new market or develop a new product. For established markets and products, syndicated research can be quite useful, but in the case of new products or technologies, such reports are less reliable.



Make the Most of Market Research



A business can dramatically improve its chances of getting valid results by clearly defining its objectives. Asking the right questions is crucial-a company should be able to clearly state what it wants to determine. It is not the responsibility of an outside research firm to identify what the client wants from a study. It is the research firm's responsibility to clearly explain its methodology and how it will approach a study.



Additionally, a research request should not be biased in favor of a particular result. Frequently, individuals who commission research have vested interests in a particular outcome. If the results are not to their liking, they try to discredit the study and ignore its results. It is best to have high-level decision-makers who have the best interests of the entire company at heart involved in the research process.



Research should not be based on an untested assumption. For example, a company should not assume there is demand for its new widget and ask a research company to find out how the product should be priced. Before developing the widget, the company should determine if there is a market for it.



Like any other investment, market research should be measured by the return it delivers. Return can be measured both by increased profitability and cost savings derived from not making mistakes. To receive any benefit, a company has to make a commitment to act on the results of a reliable research study. Market research can be a powerful business tool for those companies willing to remove their blindfolds.

Boundaries
In every era of rapid human development, boundaries that previously were thought to be sacred, have been breached. Embryonic stem cell research is no different. The controversy arises because there is experimentation on living tissue, and some would claim that this brings pain to tissue that already has human life.

Debate
This debate rages between those that claim that the good of some cannot be gained by the pain of others. So, currently, the financial resources needed for research are limited because it is a hot issue. To think debate whether government should pay for it, is a delicate topic! It’s not good for election results.

Taxes
Traditionally, taxes are paid to a government with the intent that the it makes decisions for the group, ensure the safety and wellbeing of the group and spend the accrued money on anything that the people cannot provide for themselves individually. While some would argue that this safety and wellbeing only encompasses the invasion of other countries (war), others would argue that it includes a broad spectrum of services that enhance and contribute to human beings. Ergo, embryonic stem cell research, which would provide healing for many with conditions such as Alzheimer's, 68 different cancers, auto-immune disease and healing the heart muscle, should seriously be considered as a candidate for government funding. Research, currently, is limited as a result of a short supply of. Much needs to be done and the sooner it is done, the more grief and pain will be prevented.

Fears
One of the great fears of the general populace that would discourage the government from funding stem cell research is the fear of cloning, that it would increase the difference that already exists between the haves and have-nots. If this fear can be overcome, and the benefits of stem cell research can be sold more positively. Resistance to it might fade. I have found that reasoning attributed to religious strong points often fade in the face of obvious benefits (with no accompanying negatives).

The Big Question
The greatest reason why the government should fund it is that governments were created to act as leaders for the group and to bring to the group those services which individuals cannot provide as a result of lack of sufficient individual resources.

In this instance, however, the question is whether business or government should provide the finance. Perhaps, there’s more than one solution. Perhaps, the government can provide some financial input in return for a portion of the profits. Perhaps, when research is complete, the research company would donate a certain percentage of its new technology to those that live ‘beneath the breadline’.

Conclusion
While, in many instances, health is a personal responsibility, it is unfortunate that few human beings have the capacity to live the way that optimal life styles demand. Illness is, therefore, always a probability or possibility. If governments were created to look after the wellbeing of the people, government should seriously consider investing in research that brings healing to humanity.
