Investigación y la Internet Rationale: Welcome to “Research and the Internet.” This presentation is designed to introduce your students to methods for effectively searching the World Wide Web and evaluating the content of web pages. The twenty-four slides presented here are designed to aid the facilitator in an interactive presentation of search and evaluation strategies. This presentation is ideal for the beginning of a research unit in a composition course or an Internet research assignment. This presentation may be supplemented with OWL handouts, including “Searching the World Wide Web” (http://owl.english.purdue.edu/handouts/research/r_websearch2.html), “Conducting a Productive Web Search” (http://owl.english.purdue.edu/handouts/research/r_websearch.html), and “Evaluating Sources of Information” (http://owl.english.purdue.edu/handouts/research/r_evalsource.html). Directions: Each slide is activated by a single mouse click, unless otherwise noted in bold at the bottom of each notes page.

Investigación y la Internet La Internet es una gran herramienta para la investigación, siempre y cuando tengamos la destreza para encontrar información de calidad en la Web. Sitio UDA: www.uazuay. edu.ec Rationale: With the development of the Internet, students have found that conducting research is much easier and more convenient than searching through library stacks. While the Internet can be a great tool for research, locating quality materials can at times be a challenge. The following slides will offer tips on how to make the most of your Internet search. Activity: To generate discussion, the facilitator may ask students about their level of familiarity with the Internet. Also, the facilitator may ask students about the types of web sites they visit, as well as if they have their own personal web pages.

¿Por qué debemos evaluar las fuentes de la Web? Prácticamente cualquier persona puede publicar lo que quiera en la Internet. A diferencia de las referencias escritas, las de la Web no tienen que ser revisadas, aceptadas y editadas para que se las publique. Activity: The facilitator might ask students why it is important to evaluate web sources. The answers offered on this slide highlight the importance of web source evaluation. . Key Concepts: Books and journal articles generally go through a long process of fact-checking, editing, and revising before being published. However, anyone with a computer and Internet access can post a web site. Just because the information is published online, it does not mean it is true or reliable. The facilitator may note that web sites change frequently and sometimes disappear quickly. Thinking about evaluation within the search process can help to make web browsing efficient and effective.

Investigación y la Internet Use las herramientas de búsqueda Identifique el sitio web Examine su confiabilidad Determine la profunidad y el enfoque que se da a la información Evalúe la actualidad de la información. Rationale: This slide previews the five areas of web location and evaluation that this presentation will cover.

Tipos de páginas web Informativas Personales Grupos Políticos/interés Marketing o “infomerciales” Diversión/ Entretenimiento Key Concepts: There are several different types of web pages on the Internet. Students researching the web tend to think that the majority of web pages are devoted to providing information. Generally, informative sites--pages that offer information for the public good without any type of overt political or sales agenda--are few and far between. Personal web pages tend to be devoted to an individual’s interests, hobbies, family, friends, or ideological beliefs. While researching, students may find personal web pages being used as a sounding board for a political agenda. Though some sites contain well-researched and reliable information, others do not. Political or interest group pages generally promote some type of cause or way of thinking. These sites will educate web surfers about their topics, but they may contain slanted or biased information. Their goal is to offer information in the hopes of changing a belief, gaining a vote, or earning a political contribution. Students have the hardest time distinguishing between pages that provide information and pages that try to sell a product. For example, a web site that informs about the benefits of aromatherapy may also sell aromatherapy products. While some “infomercial” sites clearly are promoting a product, the business agenda of other sites can be more difficult to assess. Finally, the Internet contains many entertainment-oriented web sites. These sites can range from movie news and games to cartoons and comic book sites. Still other pages are “joke” pages--pages that look like they contain serious information, but really contain elaborately fabricated content. If readers are not careful researchers, they may mistake these “joke” pages for reliable information. Click the mouse for each type of web site.

¿Cómo se hace una búsqueda? Una “máquina de búsqueda” es una herramienta de la Internet para encontrar páginas web y clasificarlas de acuerdo a un cierto criterio. Key Concepts: This slide defines a search engine--a tool that can search through web pages and sort them according to specified keywords. Search engines are essential for researching the Internet: they have the ability to locate and sort through millions of web pages. Activity: The facilitator may choose to generate discussion by asking students to explain what a search engine is. Click after globe appears for the answer to the title question.

Tipos de máquinas de búsqueda Yahoo Alta Vista Google, el más usado en la actualidad Dogpile, usa varias máquinas de búsqueda al mismo tiempo Varias máquinas de búsqueda se encuentran a través del sitio web de la UDA en: http://www.uazuay.edu.ec/internet/ Activity: The facilitator may ask students about they types of search engines they use. They will list many for you--Yahoo, Alta Vista, Excite, Lycos, Hotbot, Infoseek, Northern Light, Snap, Dogpile, etc. Key Concepts: Each search engine searches the web in a slightly different way. Also, companies or individuals often must register their web sites with these different search engines, so the list that comes up on Yahoo may be completely different from the one that comes up on Lycos. A wide variety of search engines may be accessed at the OWL web site, located at owl.english.purdue.edu. When researching a topic, it is also a good idea to do some brainstorming about the best places on the web to locate information. Government agencies and non-profit groups may host web sites that offer useful information. Activity: The facilitator may choose either now or after the presentation to minimize the PowerPoint presentation, access Netscape or another Internet browser, or go the the collection of search engines on the OWL web site.

Aproveche las ventajas de las máquinas de búsqueda Las máquinas de búsqueda, le permiten identificar fuentes serias: con información, productos, servicios o entretenimiento de calidad. Key Concepts: When conducting an academic search, it can be difficult to determine which sites are providing serious information, and which sites are selling a product or entertaining an audience. Some search engines, like Yahoo, will sort search information into categories, separating business and entertainment sites from other types of information. It is then up to the researcher to determine which categories to examine.

Formas de usar las máquinas de búsqueda Escoja el buscador adecuado para la investigación concretara que usted necesita. Yahoo y AltaVista distinguen entre varias categorías de sitios web. Hotbot, ubica la información basada en la popularidad del sitio web. Afine los criterios de búsqueda en lo posible. Key Concepts: Some search engines work better for specific types of searches. While Yahoo will take your keyword and sort information into categories, a search engine like Hotbot will bring up the ten “hottest” (or most popular) sites for your keyword. While Hotbot might be useful for assessing the popularity of web sites in a cultural analysis paper, Yahoo might offer a more comprehensive listing of sites.

Limite las palabras claves a buscar Or Cancer Para obtener el mejor provecho, lea siempre las instrucciones de cada máquina de búsqueda particular. Use las palabras AND y OR para limitar su búsqueda y hallar información específica. Lawsuit Tobacco Legislation Smoking Key concepts: This slide offers tips for using search engines. Since search engines do not all work in exactly the same way, it is a good idea to read the directions of your selected search engine prior to conducting a search. Also, using Boolean operators--words like “AND” and “OR”--can help to tailor a search to your needs. It is also a good idea to brainstorm a list of keywords that might fit your topic. The slide offers an example for a search on the tobacco lawsuits and settlements. Depending on the angle of your topic, you might choose a variety of these terms in combination with each other. And Advertising Teenagers

Identifique el sitio web Evalúe la calidad del sitio: principios, autores, contenidos, y objetivos. Esto es importante porque: No se revisa la precisión de los datos de muchos sitios. Algunos sitios expresan opiniones personales sobre ciertos temas, pero no necesariamente los hechos. Key Concepts: After using search engines to locate some potentially helpful web sites, your next step is to identify the site. This involves determining the authorship, content, and purpose of the web site.

Identifique el sitio web En algunos casos no se expresa con claridad los propósitos de un sitio. A veces es dificil separar lo que es verdadera información de lo que es sólo propaganda. Algunos sitios de marketing sólo les interesa vender, y no decir la verdad precisamente. Rationale: This slide details some of the problems in identifying web sites. In particular, students often have difficulty separating advertising from information.

Examine la confiabilidad del sitio ¿Quién es su autor? ¿Cuál es el grado de autoridad o experiencia de esta persona o grupo? ¿Qué información se obtiene cuando escribe el nombre del autor en una máquina de búsqueda? ¿Los objetivos de la fuente son comerciales o políticos? ¿El sitio es auspiciado por fuentes políticas o comerciales? Key Concepts: Again, asking yourself a list of questions is the best way to determine the credibility of the web site. Is the author listed? Credentials? If you can find the author’s name, try typing it into a search engine to see what else pops up. Is the author affiliated with a political group or a business? If so, try typing the name of the group into a search engine to see what else pops up.

Examine la confiabilidad ¿Hay una lista de las fuentes, una página de las citas o referencias usadas? ¿Puede encontrar estas fuentes originales? ¿Cuan confiables son? ¿Hay enlaces a otros sitios confiables para encontrar mayor información? ¿Se puede escribir por e-mail al autor o al webmaster? Key Concepts: This slide provides additional questions to test the credibility of a web page. A list of sources indicates the inclusion of source material in the web content, but it is a good idea to check out some of the sources as well. Sources listed on the Works Cited page may also prove useful to the researcher. Does the web site link to other related sites? If the linked sites are not very reliable, you may question the credibility level of the author’s own site--such links show poor judgment. Also, can the author or webmaster be contacted? If so, they may be willing to answer questions about their web site or even consent to an e-mail interview!

Determine la profundidad y el enfoque de la información ¿Se nota que el autor ha investigado: tiene referencias a otras fuentes, hipervínculos, notas de páginas, o referencias? ¿El autor considera otros puntos de vista diferentes? ¿Cuánta relación tiene la información del sitio con lo que usted está buscando? Siempre Corrobore la información! Key Concepts: This slide again offers a list of questions that students should ask when they review web sites for their depth and scope of information. Also, students need to allow themselves enough time to research their work. Encourage them not to just use information from the first five web sites they locate--they should find the five best web sites on their topics. Activity: The facilitator may ask students why the consideration of opposing points of view is important in a well-researched web site. The presence of opposing viewpoints suggest that the author has carefully considered multiple viewpoints about an issue and has come to an educated conclusion about the issue.

Determine la profundidad y el enfoque de la información ¿Hay acaso muchas imágenes, animaciones, colores y más para atraer su atención y distraerle de lo verdaderamente importante: la información? ¿No disfrazan que lo que realmente quieren es hacerle comprar algo? Key Concepts: This slide highlights the visual impact of a web site, demonstrating how easy it is to become distracted from the content by the visual appeal. All of the fireworks graphics on this page will flash briefly and disappear.

Determine la profundidad y enfoque de la información Es diferente de las fuentes impresas: La información web se presenta para una asimilación fácil y agradable visualmente La información puede no tener la profundidad y el enfoque adecuados para su investigación. El material puede tener sesgo político o comercial. Puede ser que en ocasiones las fuentes web no sean las adecuadas para encontrar la información de calidad que usted requiere para su investigación. Key Concepts: Web researchers need to determine the depth and scope of information provided on web pages. Remember, looking at the Internet on a computer monitor is very similar in some ways to watching a giant television: web pages are generally designed to be visual appealing for quick and easy digestion by the viewer. Consequently, information may not be presented as thoroughly as it might be in a book or journal article. Also, the material included on web pages may be dramatically altered to fit the marketing or political agendas of the publishers. Finally, the facilitator may want to stress that web sources are not always the best sources of information. Students sometimes tend to have an overreliance on the Internet, thinking that all information is out there somewhere in cyberspace. The best research students can do is to combine web sources with other print sources, including books, magazines, and academic journals, as well as interviews and questionnaires.

Evalué la actualidad de la información ¿Encuentra la fecha en la página web? La fecha puede corresponder a: La que el autor escribió el artículo La que estuvo disponible por primera vez en la Web La de más reciente modificación (revisión, aumento, disminución, eliminación) Key Concepts: Though information on web sites may be credible, it may not be current. The date of the material may be completely omitted from the web site. To be sure you are covering all of the recent changes in the field or topic you are studying, be sure to assess the currency of your information. This is not always an easy task.

Evalúe la actualidad de la información ¿Se encuentra claramente en el sitio la fecha de creación o la de más reciente actualización? Lo más importante: ¿La información contempla los cambios o avances recientes en el ámbito de su investigación? Key Concepts: Some sites will state at the bottom of the home page statements such as “Date of Creation: 6/1/99” or “Updated 7/7/99.” If dates are clearly stated in this way, you should be able to rely upon them. However, rely upon your context clues. Does the information provided cover recent changes or advances in your topic? If not, the information is probably outdated. Example: For example, if your topic is cloning and you located a web site that discusses cloning as if it had not taken place yet, you would know that the information was published before Dolly, Gene, and other famous cloning experiments were successfully completed.

Evaluación de fuentes web Aproveche las ventajas de las máquinas de búsqueda Identifique el sitio web Examine su confiabilidad Determine profundidad y enfoque de la información Evalúe la actualidad de la información Rationale: This slide reemphasizes the main points of the presentation. This is a good time for the facilitator to field any questions about the presentation content. Activity: Click on the OWL hyperlink and visit the collection of search engines on the lower left section of the page. Ask students to imagine that they will write a paper about US tobacco lawsuits. Have them go to Hotbot and type in the keyword “tobacco.” Hotbot will provide the ten “hottest” sites with that keyword; the majority of them will be tobacco shops, companies selling methods to stop smoking, and smoking afficianado pages. You may find one or two sites related to the lawsuits. Then have your students try the same search in Yahoo. They will find information categorized into sections relating to business, hobbies, health, and news. Note that Yahoo can help to identify the types of web sites you visit, saving time and energy in the search process. You might then choose to have students come up with pairs of keywords to enter into the site, such as “tobacco and legislation” or “smoking and lawsuits.” This will refine the search even further. Visit the Mankato (Minnesota) web pages and ask your students to assess their reliability. The official web page is located at <http://www.ci.mankato.mn.us>. Another page is located at <http://www.lme.mankato.msus.edu/mankato/mankato.html>. This page is posted by Mankato State University, and it is designed as both a joke and an exercise in assessing the reliability of web pages. Have students follow the links on the site, notice the pictures, and the many awards and press listings noted at the bottom of the home page. Then have students read the “Disclaimer” flashing at the top of the screen (be sure to jump to Part Four). The letter from Maureen Gustafson is also a treat. Just because a page LOOKS like it might be reliable doesn’t mean it is. Visit a search engine of your choice and ask your students to provide some search terms for some sample class searches and web page evaluations.
