Objectives:

1. Students will retrieve records from WilsonWeb’s OmniFile full text database utilizing at least three
   different Boolean operators, using a combination of All Smart search and specific field searches
   (i.e. Title, Subject, Abstract).

2. Students will record and evaluate the total number of results for each search and the number of
   records returned with a relevancy rating between 80-100%, if reasonable.

3. Students will identify and print articles with a relevancy rating above 70% which fulfill their
   information needs.

4. Students will e-mail a citation entry for each article to their account.

5. Students will summarize information from their article(s) which answer, either completely or in
   part, questions generated during brainstorming.

6. Students will synthesize data to create informative speech script with citations.

Standards Addressed:

1. American Library Association: The Nine Information Literacy Standards for Student Learning.
   • Standard 1: The student who is information literate accesses information effectively and
     efficiently.
   • Standard 2: The student who is information literate evaluates information critically and
     competently.
   • Standard 3: The student who is information literate uses information accurately and creatively.

2. Nebraska L.E.A.R.N.S.: Reading/Writing Standard for Twelfth Grade
   • 12.1.2 By the end of twelfth grade, students will locate, evaluate, and use primary and
     secondary resources for research.

Materials Needed:

1. Computers with Internet connection for each student and a printer. (Lab, Library or Cart)
2. Students need to have with them the handout containing both the NebraskAccess URL and Login
   information and Boolean search terms, their brainstorm graphic organizer of key terms and list of
   questions (previously completed in class), form for logging search results, instructions for e-
   mailing citation entry, Informative speech directions and exit survey.
3. Teacher should be prepared with additional copies of NebraskAccess/Boolean search handout, a
   checklist for recording which students have successfully completed their logging sheet and sent
   an e-mail citation to themselves, and informative speech rubric.
4. Highlighters, staplers, folders, dictionaries, thesauruses.
Anticipatory Set:

What is Boolean language? How does it work? How can Boolean searches help you reduce the
number of unrelated or useless results during a search? These questions would be posed the day
before class. Students could be awarded bonus points for coming to class with answers to these
questions. In class, the instructor will present a summary sheet of some common Boolean terms with
a brief summary of the theory behind the operators.

Prior to the following lesson plan, the students would have spent a day reviewing the concepts of
paraphrasing, summary and the proper handling of quotes. Then, they would have spent two or three
days learning how to use a MLA works cited page and in-text citations and the advantages of
databases verses the Internet with regards to authorship and reliability. As a last step before this
lesson, the students would have identified a subject (approved by teacher), created a list of 15-20
questions regarding what they wanted to learn/share about their topic and developed a graphic
organizer of key terms and phrases to use in their searches, based on questions.

Step-By-Step Procedures:

1. Students will previously have been shown how to log onto the school’s computers. They will be
   instructed to login and start up the Internet program, i.e., Safari, Internet Explorer or Firefox.

2. Students will then be instructed to enter the NebraskAccess URL and to proceed with login once
   the page has loaded (their handout will also include login instructions for use at home). Provide
   verbal support during this step, reading through the instructions aloud (option for using overhead
   or PowerPoint slide show).

3. Students will be instructed to select WilsonWeb’s OmniFile Full Text database.

4. Students will enter at least three search queries, each containing a unique combination of their
   previously brainstormed words/ideas and the Boolean search terms provided on the handout.
   Remind them to select some field specific searches (title, subject, abstract). Inform the students
   that words must be spelled correctly and Boolean terms need to be entered in the correct format,
   i.e., the use of brackets or capitalization (refer to handout). Encourage them to use the provided
   thesauruses and dictionaries.

5. After each search, students will record the exact word(s) or phrase(s) and Boolean operator(s)
   entered and the total number of records returned by the search. If feasible, they should also
   indicate the number or percentage of records with a relevancy percentage between 80-100%. If
   students complain of either too few or too many results, instruct them to examine how specific or
   general their search queries were. Suggest they try either combining or reducing terms to achieve
   the desired results.

6. Instruct students to go through their results and begin reading abstracts or skimming text to
   identify sources with information which will enable them to answer the questions they composed
   prior to keyword brainstorming.

7. Once they have located a potential source, they should e-mail themselves the citation following
   the instructions provided in their handout. After e-mailing the citation, they should print the article.
   Later, they will be expected to read and summarize the important information using either note
   cards or the Cornell note taking method. The teacher will mark the assessment sheet as each
   student indicates/proves completion of this task.
8. Before the end of class, remind students of the instructions provided for remote access to the
   databases from home. They may continue research on their own if not finished by end of period.

Plans for Independent Practice:

Students will be encouraged to continue their searches from home or during study periods. Students
will be expected to read and summarize their sources in the days to come. Students will compose
speeches utilizing information obtained using Boolean search.

Assessment Based on Objectives:

•   Students will chart search entries and compiled results for each.
•   Check off sheet marked as students complete search and e-mail tasks.
•   Students will create note cards or Cornell notes from retrieved articles.
•   Students will compose speech which includes facts obtained from articles. MLA citation will be
    required (instruction regarding MLA citation would be done prior to this exercise).

Adaptations (For Students with Learning Disabilities or Gifted Students):

Lessons for LD students should be modified in accordance with their IEPs: Reduction in the number
of searches and/or required elements, verbal support with instructions, visual depictions with
illustrations or modeling, assistance with reading comprehension (oral support).

Lessons for Gifted: Assign a reflection essay that assesses prior and post understanding of
constructing searches and finding/recognizing relevant data. Instruct them to reflect on how this
assignment impacted their progress towards being information literate, with reference to at least one
of the standards.
