Ch 1: Praxis Environmental Education: Scientific Inquiry Processes in Environmental Science

About This Chapter

Let this chapter help you understand the processes used in scientific inquiry. These video lessons and self-assessment quizzes will give you the information you need to answer these types of questions on the Praxis Environmental Education test.

Praxis Environmental Education: Scientific Inquiry Processes in Environmental Science - Chapter Summary

The lessons in this chapter will acquaint you with scientific inquiry processes and help you get ready for the Praxis Environmental Education exam. You will learn to identify scientific problems and develop testable hypotheses and the tests to prove them. Other lessons cover assessing the validity of data and interpreting data. These videos contain material that will help you correctly answer exam questions concerning these topics:

  • Steps, terms and examples of the scientific method
  • Scientific evaluation of environmental problems
  • Formulating a research hypothesis and a null hypothesis
  • True experimental design
  • Research variable: dependent, independent, control, extraneous and moderator
  • Experimental observation, inference and prediction
  • Validity and reliability of scientific sources
  • Drawing conclusions from scientific investigation
  • Using observational data and peer-reviewed research
  • Problems with scientific inquiry

These brief video lessons are led by expert instructors who know how to make learning fun while teaching you what you need for the exam. The self-assessment quizzes at the end of each lesson let you gauge your knowledge on scientific inquiry processes.

Praxis Environmental Education: Scientific Inquiry Processes in Environmental Science Objectives

Praxis subject examinations evaluate the knowledge of individuals seeking teaching credentials in specific subjects. Many states require that candidates pass the Praxis in order to obtain a teaching license. The Praxis Environmental Education exam contains 130 multiple-choice questions. It is a paper, not computerized, test, and you will be allowed two hours to complete it.

The exam is divided into six sections. Questions on scientific inquiry are part of section I, Nature of Environmental Science Education: Inquiry, Methodology and Techniques. This section contains 20 questions, which make up 15% of the total test. The questions may require you to define terms, show your understanding of important concepts and apply and analyze information to solve problems.

The Scientific Method: Steps, Terms & Examples

1. The Scientific Method: Steps, Terms & Examples

The scientific method is a set of principles and procedures followed to gain knowledge through making questions and observations, performing experiments, and formulating and testing a hypothesis. Explore the key elements and real-life applications of the scientific method.

The Scientific Method Applied to Environmental Problems: Definition, Steps and Applications

2. The Scientific Method Applied to Environmental Problems: Definition, Steps and Applications

Environmental problems can be investigated in a systematic way using the scientific method. Explore the steps of the scientific method: observations and questions, hypothesis, experiment, interpreting results and making conclusions. Discover the definition and applications of the scientific method in this lesson.

Scientific Evaluation of Environmental Problems: Process and Steps

3. Scientific Evaluation of Environmental Problems: Process and Steps

The scientific evaluation of environmental problems is an effective method of asking questions, making observations, and conducting experiments to learn more about a specific environmental issue. Learn about the process of scientific evaluation and the five-step process to solve environmental problems.

Formulating the Research Hypothesis and Null Hypothesis

4. Formulating the Research Hypothesis and Null Hypothesis

Generally, research projects are designed to test a hypothesis, which is a statement of the condition to be studied or the question to be answered. Research projects actually prove or disprove a null hypothesis, which states the opposite of the hypothesis. Learn how to formulate the research hypothesis and null hypothesis, including research questions and if/then statements, and understand the concept of invalid hypothesis.

True Experimental Design

5. True Experimental Design

Many fields of study rely on experiments--such as control groups, experimental groups, and random assignments--to conduct research and gain knowledge. Learn about true experimental design, understand the importance of samples and population in experiments, and identify the differences between independent and dependent variables.

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

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

In experimental research, factors that have any varying quality or quantity are known as a Variable. Discover the uses of Independent, Dependent, Control, Extraneous, and Moderator variables in conducting research.
