Ch 1: OAE - Biology: Scientific Inquiry

About This Chapter

We can help you brush up on subjects involving scientific inquiry for the OAE Biology exam with our informative video lessons. Topics include scientific theory, experimental design, sampling techniques, and more!

OAE - Biology: Scientific Inquiry - Chapter Summary

The OAE Biology exam not only tests your knowledge of biology topics, but also your grasp on the purpose of scientific inquiry and the basic methods scientists utilize for their research. With the help of these video lessons you should be able to:

  • Articulate the nature of science and the value of research
  • Explain the various steps of the scientific method
  • Form your own scientific hypotheses
  • Define scientific theory and list its characteristics
  • Describe a few of the sampling techniques used in scientific experiments
  • Catalogue the different types of research methods
  • Differentiate between dependent, independent, control, extraneous and moderator research variables
  • Contrast inductive and deductive reasoning
  • List major advancements in the field of science and technology since 1945

Each video lesson has been planned out by our experienced instructors to make learning easier for you. Try out our multiple-choice self-assessment quizzes to see how prepared you are for the OAE Biology exam.

OAE - Biology: Scientific Inquiry - Chapter Objectives

There are five domains on the OAE Biology exam. The lessons in this study guide prepare you to answer those questions about scientific inquiry that appear in the Nature of Science domain. This domain constitutes 20%, or 30 questions, of the total exam. You'll have three hours to answer all 150 multiple-choice questions on the exam. Each question is stand-alone and equally-weighted.

The OAE exams are the Ohio state licensure exams for teachers. Educators who aspire to teach life science classes to students in 7th through 12th grade need to score a 220 on the OAE Biology exam. Questions are aligned with a pre-established standard of pedagogical knowledge determined by the the Ohio's New Learning Standards.

The Nature of Science

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.

What is Scientific Research?

2. What is Scientific Research?

This lesson will discuss important components of scientific research, including the scientific method, peer review, statistical significance, and more!

The Scientific Method: Steps, Terms & Examples

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.

Developing a Scientific Hypothesis

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.

What is the Scientific Theory? - Definition, Characteristics & Example

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.

True Experimental Design

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.

Sampling Techniques In Scientific Investigations

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.

What Are The Different Kinds of Research Methods?

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.

Research Variables: Dependent, Independent, Control, Extraneous & Moderator

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?

Inductive vs. Deductive Reasoning: Differences & Examples

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.

The Advance of Science & Technology Since 1945: Developments & Impact

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.

What is Negative Feedback in Biology? - Definition & Examples

12. What is Negative Feedback in Biology? - Definition & Examples

Negative feedback is a key regulatory mechanism for physiological function in living things. Learn the definition, explore some examples and find out how this process happens in your body. Test your new knowledge at the end with a quiz.
