Students will review the Introduction to Database Vocabulary Handout the night before class. Introduction MI Introduction (LSI Quadrant I): ASK, Did you know you have a very sophisticated database right inside your body? SAY, That s right! It s your amazing brain! In addition to maintaining your breathing, blood flow, body temperature, and other aspects that allow us to stay alive, it also constantly receives, sorts, and stores a vast amount of information, or data. This is also what databases do it stores and organizes tons of data such as inventory, customer contacts, diet and exercise records, household expenses, etc. SAY, Today, we ll be introduced to the some database software, and we will learn when/why to use the software. Outline MI Outline (LSI Quadrant II): Instructor Notes: Instructors can use the presentation, slides, handouts, and note pages in conjunction with the following outline. Be certain to review the Introduction to Databases Activity Sheet document Review the vocabulary terms previously given to the student using the Introduction to 2

3 before presenting the lesson. I. Define terms/concepts associated with the lesson a. Data - Bits or pieces of information. b. Database A collection of data organized and cross-referenced for quick retrieval. c. Template A pre-built database table formatted with categories such as those for business, education, and personal use including events, assets, inventory, and contacts. d. Table The main function of a table in a database is to organize and store data. Tables are arranged in rows and columns making it easy to search, extract data from, and reference information. e. Related Table A table that links or references information from another table, eliminating the need to duplicate data entry. f. Record A group or set of related data. g. Field The location for a piece of data or information. h. Form Shows data for entry or review and is selected from one or more tables or queries. i. Query A process for pulling data from tables for informational or reporting purposes. j. Report Shows data for printing, display, or interaction and is selected from one or more tables. Databases Vocabulary Presentation. Students will complete the Introduction to Databases Vocabulary Review as part of the lesson summary. Use the Introduction to Databases Lesson Outline" presentation to guide you as you demonstrate the main concepts within a database program. II. Discuss the relevance of using databases a. Organization of vast amounts of data i. Discuss how overwhelming it would be to organize and keep track of employee information for a large retail corporation with 1.5 million employees. III. Explain the benefits of using a database as opposed to a workbook or spreadsheet. a. On the surface, both types of software seem similar. After all, they store data, and you can enter data in a grid of cells. b. The question is, How do you want to organize your data? c. Database software has a relational Have the students complete the "Intro to Databases Outline Organizer" as you present the lesson 3

Spreadsheet software is used for analyzing numbers using formulas, while database software is used for the storage of large amounts of data that can be accessed easily and quickly. Demonstrate selecting a template and entering data into the database. a. Demonstrate using the following tools/features (SEE GUIDED PRACTICE) i. Navigating to and opening the database software ii. Selecting and downloading a pre-built template from the database software package or the internet iii. Beginning a new database and entering data about a particular item in the classroom (a computer or projector is a good item) iv. Saving the new asset V. Explain Independent Practice Activity a. Students will brainstorm the fields needed to enter home inventory information for insurance purposes. (Ex. Item Name, Description, Model/Part Number, Estimated Purchase Price, etc.) b. Students will be responsible for inventorying at least 25 items from their home. c. They will create their own database using the skills taught in this lesson to create a home inventory database. Review the Independent Database Creation instruction with the students (See Introduction to Databases Activities ). Give each student a copy of the Home Inventory Database Evaluation Rubric. Review the rubric with the students. Application MI Guided Practice (LSI Quadrant III): The teacher will use database software and demonstrate how to select and download a pre-built template from the database software package or the internet. The students will enter and save a new asset choosing something from the classroom. Ask for one or two volunteers to re-demonstrate in front of peers. Encourage students watching to peer-coach and evaluate the student demonstrator on his or her techniques. 4

5 MI Independent Practice (LSI Quadrant III): Students will work on their personal home inventory databases independently. Summary MI Review (LSI Quadrants I and IV): Q&A Session Q: What is data? A: Data is bits or pieces of information. Q: What is a database? A: A collection of data organized and cross-referenced for quick retrieval.. Q: Why is it important to use a database to organize data? A: Because it allows you to organize and make better informed decisions about vast amounts of data that is related but constantly changing. Q: What s the difference between using spreadsheet software and using database software to organize data? A: Spreadsheet software is used for analyzing numbers using formulas, while database software is used to store large amounts of data. Introduction to Databases Vocabulary Review Activity Students will complete the fill-in-the-blank Introduction to Databases Vocabulary Review as a review of the lesson. Afterwards, the teacher will go through the worksheet with the class. Evaluation MI MI Informal Assessment (LSI Quadrant III): 1. Teacher will observe student demonstrators and observers during guided practice to assess student understanding of concepts and techniques. Revision/re-teach will occur as needed before moving to Independent Practice portion of the lesson. 2. Teacher will circulate through the lab as students work independently to redirect/re-teach as necessary. Formal Assessment (LSI Quadrant III, IV): Teacher will use the Home Inventory Database Evaluation Rubric Extension MI Extension/Enrichment (LSI Quadrant IV): 1. Make this independent practice relevant and meaningful by explaining why home inventory is important. EX. Give the following scenario: If your house ever burned to the ground, the insurance company would need an inventory of the valuable items in your home to determine the replacement value. 5

11 Introduction to Databases Activities Class Brainstorm/Discussion: Instructions for Teacher: During the lesson, involve the entire class in discussions/brainstorms about the relevance of using databases, specifically large companies with vast amounts of data. During the explanation of the Independent Practice, have students first brainstorm fields for the home inventory project. This will help re-enforce the concepts of records and fields. Class participation in Teacher Demonstration: Instructions for Teacher: As you demonstrate selecting and downloading a pre-built template, get student buy-in by involving them in the process. Students will observe, but then ask for one or two volunteers to re-demonstrate in front of peers. Encourage students watching to peer coach and evaluate the student demonstrator on his or her techniques. Independent Database Creation: Instructions for Teacher: Students will independently inventory 25 home items and enter the data into their database. Instructions for Student: Now that you ve seen me demonstrate some of the tools/features available in the database software, you re going to get to create your own personalized home inventory database and apply the skills we ve learned today. You will need to first inventory at least 25 items of value from your own home. You will enter the data into the database program using a prebuilt template with the fields we came up with today. 11
