- Determining the steps and terms associated with scientific method
- Understanding how to develop a scientific hypothesis and identify characteristics of scientific theory
- Examining true experimental design and sampling techniques in scientific investigations
- Detailing different kinds of research methods and various research variables
- Comparing and contrasting inductive and deductive reasoning
- Exploring the advance of science and technology since 1945
Take advantage of lessons featuring experienced instructors with a wealth of knowledge in scientific inquiry. You can also direct questions about any lesson topics you don't understand to expert tutors and coaches who are eager to help.
AEPA General Science: Scientific Inquiry Chapter Objectives
A primary objective of the AEPA General Science: Scientific Inquiry chapter is to ensure you feel confident in your ability to answer questions related to scientific inquiry on the NES General Science assessment. In addition to reviewing the videos in this chapter, you can access full transcripts to get a written version of the lessons. Timelines are available below the videos that allow you to skip to key topics within the lessons. This can help you predetermine which topics you need to review most and easily revisit any that you need to review.
The topics covered in this chapter are found in the nature of science content domain of the exam, which constitutes approximately 19% of the total test. You will be required to take the test on computer and answer 150 multiple-choice questions. Your results will be available immediately after testing, with a score report released within two weeks. In order to pass, you must earn at least a 220.
1. The Nature of Science
This lesson will explore the basic nature of science. It will distinguish science from pseudoscience and hypothesis from theory and natural law; it will give plenty of examples of each.
2. What is Scientific Research?
This lesson will discuss important components of scientific research, including the scientific method, peer review, statistical significance, and more!
3. The Scientific Method: Steps, Terms & Examples
The scientific method is more than just hypotheses and experiments. In this lesson, we'll explore the themes and variations that make up the world of science.
4. Developing a Scientific Hypothesis
This video describes how to create a hypothesis and includes the three main things needed to create a strong hypothesis. You'll learn how to make a clear statement that can be both tested and measured.
5. What is the Scientific Theory? - Definition, Characteristics & Example
In this lesson, you'll learn the definition and characteristics of a scientific theory and understand how theories are formulated. You'll see examples of scientific theories, and after the lesson you can test your knowledge with a brief quiz.
6. True Experimental Design
Experiments are the classic way to conduct research in almost any field of study. But do you know how true experiments really work? This lesson explains the details of experimental design, such as different types of samples, control groups and independent vs. dependent variables.
7. Sampling Techniques In Scientific Investigations
We can learn a lot by gathering information from a small subset of a larger group. By sampling this smaller group, scientists can save time and money while still gaining a good understanding of the population as a whole.
8. What Are The Different Kinds of Research Methods?
This lesson will go over some important research methods, including observation, correlation, and experimentation, as well as examples of each type of methodology.
9. Research Variables: Dependent, Independent, Control, Extraneous & Moderator
This lesson explores the terminology of experimental design. What are variables? How do they influence each other? Is it possible that you are seeing connections that don't actually exist?
10. Inductive vs. Deductive Reasoning: Differences & Examples
This lesson explores the difference between inductive and deductive reasoning in the form of psychological experiments. In addition to defining these terms, the lesson gives examples to explain how this reasoning is applied.
11. The Advance of Science & Technology Since 1945: Developments & Impact
In this lesson, we explore just a few of the numerous advances and innovations made in the worlds of sciences and technology, from automobiles and televisions to computers and phones that can fit in the palm of your hand.
12. The Role of Scientific Knowledge in Research & Peer Review
Learn about how research and peer review leads to scientific knowledge through the scientific process, and discover some of the key elements and themes in science.
