Using the Student Lessons

The heart of this module is a set of classroom lessons. These lessons are the vehicles that we hope will convey important concepts related to sleep and its physiological functions, and biological rhythms, as well as sleep disorders and the effects of sleep deprivation. To review the concepts in detail, refer to the chart Conceptual Flow of the Lessons.

Format of the Lessons

As you scan the lessons, you will find that each contains several major features.

At a Glance gives you a convenient summary of the lesson.

• The Overview provides a short summary of student activities.
• The Major Concepts section states the central idea(s) that the lesson is designed to convey.
• Objectives lists specific understandings or abilities students should have after completing the lesson.
• Teacher Background specifies which sections of the Information about Sleep relate directly to the student lesson. This reading material provides you with the science content that underlies the key concepts covered in the lesson. The information provided is not intended to form the basis of lectures to students. Instead, it enhances your understanding of the content so that you can more accurately facilitate class discussions, answer student questions, and provide additional examples.

In Advance provides instructions for collecting and preparing the materials required to complete the activities in the lesson.

• Web-Based Activities tells you which of the lesson’s activities use the World Wide Web site as the basis for instruction.
• Photocopies lists the paper copies or transparencies that need to be made from masters, which follow the student lesson.
• Materials lists all the materials other than photocopies needed for each of the activities in the lesson.
• Preparation outlines the things you need to do to be ready to teach each of the activities in the lesson.

Procedure outlines the steps in each activity in the lesson. It provides implementation suggestions and answers to questions.

Within the procedures, annotations provide additional commentary.

• Assessment provides you with strategies for assessing student progress throughout the module, and is identified by an assessment icon.
• Icons identify specific annotations:

identifies teaching strategies that address specific science content standards as defined by the National Science Education Standards.

identifies when to use the World Wide Web site as part of the teaching strategies. Instructions in the Procedure section tell you how to access the Web site. Additional information about using the Web site can be found in Using the Web Site. A print-based alternative to Web activities is provided in case a computer with Internet access is not available.

identifies a print-based alternative to a Web-based activity to be used when computers are not available.

identifies when assessment is embedded in the module’s structure. An annotation suggests strategies for assessment.

The Lesson Organizer provides a brief summary of the lesson. It outlines procedural steps for each activity and includes icons that denote where in each activity masters, transparencies, and the Web site are used. The lesson organizer is intended to be a memory aid for you to use only after you become familiar with the detailed procedures for the activities. It can be a handy resource during lesson preparation as well as during classroom instruction.

The Masters to be photocopied are found at the end of each lesson.

Timeline for the Module

The Suggested Timeline (below) outlines the optimal plan for completing the lessons in this module. The plan assumes you will teach the lessons on consecutive days. If your class requires more time for completing the procedures, discussing issues raised in this module, or completing activities on the Web site, adjust your timeline accordingly.
