Types of research design, assessing the quality of a research study and the importance of review boards are also covered. After you finish all the lessons in this chapter, you should be able to:
- Explain the difference between experiments and observational studies
- Evaluate data and interpret scientific graphs and correlations in research
- Handle biological specimens safely
- Point out the ethics of using animals in experiments
- Discuss how scientific objectivity affects scientific progress
- Identify important events, contributions and theories in science
- Summarize the risks and benefits of scientific advancements
Managing your studies through the dashboard allows you to get a quick view of your course progress and recent activity. Convenient links to practice quizzes let you check your understanding of the content before continuing to another lesson. On the dashboard, you'll also be able to ask questions of our subject experts.
1. The History of Science: Events, Contributions & Theories
In this lesson, we discuss a few significant events in science's history. We will see how science has changed over the years as we start to question what we think we know.
2. What is Scientific Investigation? - Definition, Steps & Examples
Scientific investigation is the way in which scientists and researchers use a systematic approach to answer questions about the world around us. Read on to find out more. A quiz is provided to test your understanding.
3. What is Scientific Research?
This lesson will discuss important components of scientific research, including the scientific method, peer review, statistical significance, and more!
4. Types of Research Design
There are questions to be answered in all areas of psychology. How are these questions answered by professionals in the field? This lesson covers several different options researchers can use to approach such questions.
5. Experiments vs Observational Studies: Definition, Differences & Examples
There are different ways to collect data for research. In this lesson, you will learn about collecting data through observational studies and experiments and the differences between each.
6. Evaluating Data from Scientific Investigation
After watching this video, you will be able to explain the meaning of the terms 'accuracy' and 'reproducibility,' or precision, as they relate to science experiments. A short quiz will follow.
7. How to Read Scientific Graphs & Charts
How do scientists summarize their findings with visual aids? In this lesson, explore the different types of tables, charts and graphs that scientists use. Learn to read these effectively as a preview to your science studies.
8. How to Interpret Correlations in Research Results
Perhaps the most common statistic you'll see from psychology is a correlation. Do you know how to correctly interpret correlations when you see them? This lesson covers everything you need to know.
9. Validity and Reliability: How to Assess the Quality of a Research Study
Many psychologists and teachers complete research studies. How can you tell if a study was done well? This lesson will cover many criteria for a good quality study, including types of reliability and validity.
10. Working with Biological Specimens Safely in the Lab
Working with biological specimens can be interesting and rewarding. But we need to be careful when handling and disposing of these types of specimens because they do have the potential to do harm both in and out of the lab.
11. Use of Animals In Experiments: Ethics & Concept
Learn about using animals in experiments according to ethical guidelines set forth by the American Psychological Association, including the ethical and unethical use of animals in past research experiments, and test your knowledge with a quiz.
12. The Importance of Institutional Review Boards in Research
If you think a researcher just runs an experiment, then you didn't know they would run the risk of losing both their position as a researcher and possibly their freedom. The importance of the Institutional Review Boards keeps them safe.
13. How Scientific Objectivity Influences Scientific Progress
Scientists make new discoveries by making careful observations and analyzing results in a way that is honest, objective, and based on what is already understood. This lesson will define objectivity and explain why it is important to scientific progress.
14. How Science Has Changed Society
Without science, our modern world just wouldn't be the same. The way we travel, shop, learn, socialize, eat, work, and play is possible because of scientific influences and innovations. Take a look around, and you'll see science pretty much everywhere!
15. Scientific Research & Technological Advancements: Risks & Benefits
How are science and technology related? What are the risks and benefits of technological advancement? Learn how technology has improved our lives and created potential problems. After, take a quiz to see how your knowledge has advanced!
