  1. Using the Internet - Effectively! Craig L. Scanlan, EdD, RRT, FAARC Professor and Director MS and PhD Programs in Health Sciences UMDNJ-SHRP

  2. Workshop Objectives • Identify the tools needed to exploit the Internet for learning • Search for, evaluate and find quality online learning resources • Communicate and collaborate with other learners online • Successfully manage one’s online learning experiences

  3. But First - a Pretest! (demonstration of automatically scored online self-assessment)

  4. Educational Uses of the Internet – A Short Tour • Communicating/collaborating • Getting and sharing information • Professional development

  5. Communicating & Collaborating • E-mail and attachments • LISTSERV (targeted group E-mail) • UseNet and threaded discussion • Collaboration software • “Chatrooms”

  6. Getting & Sharing Information • Getting • NLM Medline database • World Wide Web Information • Sharing • Web Publishing • Personal Databases

  7. Professional Development • Online Tutorials • Online Courses and Degrees • Online Continuing Education Take a Self-Assessment for Online Learning

  8. Tools You Need

  9. What is the Internet? • 100,000+ computers • One billion+ ‘pages’ • Linked via world-wide networks • Includes e-mail, WWW, Telnet, Usenet, etc • Accessible to all

  10. Key Components of the Internet

  11. ‘Basic’ Toolset • Internet Access • Web Account (College or ISP) • Web Publishing Tools • Word Processor (Saves HTML) • HTML Editor • FTP Client • Telnet Client

  12. Internet Access • Computer • Internet connection • Internet service provider • Browser software • Remote software* *(if combined home and office work plan)

  13. Internet Connections

  14. Factors to Consider in Selecting anInternet Service Provider (ISP) • Connection (dial-up, DSL, cable) • Download/Upload Speed • Cost (hourly/monthly/fees/contracts) • Reliability • Software/’Extras’ • Technical Support

  15. Highly Rated National ISPs* • @Home (cable) • MindSpring • AT&T WorldNet • EarthLink • MediaOne (cable) *AOL, Compuserve, MSN, Prodigy, Juno rated below average

  16. Browser/E-Mail Client • NetscapeCommunicator • MS Internet Explorer withOutlook Express Don’t forget plug-ins!

  17. Finding and Evaluating Quality Online Learning Resources

  18. Scenario • Your facility is planning to implement a cardiac rehabilitation program • The director wants you to prepare a report on cardiac rehabilitation that includes a review of program models and their evaluation and any guidelines that may apply

  19. Example – the Wrong Way The wrong way: Go on line, do a quickie computer search using “cardiac rehabilitation,“ bada-bang, bada-boom!

  20. Locating Relevant Source Documents • Primary Sources • ‘Journal Articles’ • Conference Abstracts • Research Reports • Theses and Dissertations • Secondary Sources • Books • Literature Reviews • the ‘Popular Literature’ • Internet/World Wide Web

  21. Clinical trial Literature review Cross-sectional study Case report Meta-analysis Multicenter trial Feasibility study Letter to editor Survey of practice Case-control study Consensus statement Practice guideline Review of cases Cohort study ‘Journal Articles’

  22. Where to Search • Primary Sources • Computerized structured databases • Manual • Cumulative indices • Journal indices • Secondary Sources • Library ‘Card Catalog’ • Books in Print • WWW Search

  23. Structured Databases(Using Controlled Vocabularies) • Journal Articles (use specific database’s terms index) • MEDLARS: Medical Subject Headings (MeSH) • CINAHL: subject heading tree/permuted index • Excerpta Medica (Embase): EMTREE • Books and Monographs: • library cataloging system ( Dewey, NLM, LoC)

  24. Medical Subject Headings (MeSH) • The MeSH Supplement to Index Medicus® (alphabetical and hierarchical listing of terms) • The MeSH Annotated Alphabetic List (an alphabetic listing includes notes/ historical info) • The MeSH Tree Structures (a hierarchical listing) • The Permuted MeSH (a listing of each significant word or root appearing in any MeSH heading) • NLM’s Online MeSH Browser • Key Term Mapping/Translation (e.g., OVID)

  25. Example: ‘Chest X-Rays’ “Chest x-rays" not a MeSH term Using Permuted Index + MeSH Tree: Diagnosis [E01] Diagnostic Techniques and Procedures [E01.370] Diagnostic Imaging [E01.370.350] Radiography [E01.370.350.700] Angiography [E01.370.350.700.060] + Fluoroscopy [E01.370.350.700.225] + Mammography [E01.370.350.700.500] + Neuroradiography [E01.370.350.700.560] + Radiography, Abdominal [E01.370.350.700.715] + Radiography, Dental [E01.370.350.700.720] + Radiography, Interventional [E01.370.350.700.725] Radiography, Thoracic [E01.370.350.700.730] Tomography, X-Ray [E01.370.350.700.810] +

  26. Boolean ‘OR’ A OR B Example: “asthma OR exercise” yields pages that include either word; e.g., aerobic exercise and atopic asthma

  27. Boolean ‘AND’ A B A&B Example: “asthma AND exercise” yields pages that include both words

  28. Boolean ‘NOT’ A NOT B Example: “asthma NOT exercise” yields pages that include asthma but not exercise

  29. Demonstration UsingFree NLM MedlinePubMed

  30. The Web as an Information Source

  31. The Problem Knowledge Information “The Web is the ultimate expression of too much data and not enough information” David Seuss, CEO, Northern Light Data

  32. Finding Your Way Around • Random surfing • Link Pages • Directories • Search engines • Metasearch tools UC Berkeley Tutorial : Finding Information on the Internet

  33. Random Surfing • No Road Maps • Low ‘Hit Rate’ • Time-Consuming • Easy to Get Off Track • But…Fun

  34. Link Pages (PT Examples) • Andrews University • Cal State – Long Beach • Univ Kansas Medical Center • PTNetwork.com

  35. Internet Directories • Provide categorized lists of Web sites, constructed by humans (professional and/or volunteer editors) • Tend to be selective rather than all-inclusive (most aim for quality over quantity) • Usually include searchable database containing descriptions of the directory’s Web sites • Require some knowledge of subject matter • Some categories can quickly become outdated

  36. Internet Directories • General Directories, e.g.Yahoo! • Medical Directories (Examples) • Medscout • Galaxy Medical List • Achoo • MedWeb • Hardin MD

  37. Search Engines • A computer-generated index of all the infor-mation found on all searched Web pages • Aims to include all Web pages that contain the information, but without assessing quality • Takes you to the exact page on which the words you are looking for appear • Regularly updated by automated processes

  38. Top 7 Search Engines (By Coverage) • Google • WebTop • Alta Vista • Fast (‘All theWeb’) • Northern Light • Excite • Inktomi (HotBot, MSN, Snap) • Go (Infoseek)

  39. Search Engine Coverage KEY: GG=Google, WT=WebTop, AV=AltaVista, FAST=FAST, NL=Northern Light, EX=Excite, INK=Inktomi, Go=Go (Infoseek)

  40. Improving Search Results • Boolean Operators • AND • OR • NOT • Search Engine ‘Math’ • Proximity • Near • With • Wildcards

  41. Search Engine ‘Math’

  42. Without With asthma exercise asthma exercise Proximity Searching “Asthma NEAR exercise”

  43. Wildcard (Truncation) Searching Asth* * substitutes for any characters Yields asthma, asthmatic, asthmatics, asthmaticus, but also asthenia

  44. Other Search Engine Tricks* • Search by domain (e.g., “edu”, “gov”) • Search by URL (e.g, “umdnj.edu”) • Search by document title • Search by popularity/hits (DirectHit) *For more tips/tricks: Powersearching for Anyone (SearchEngineWatch)

  45. Metasearch Tools • Metasearch tools search the search engines • Best tools rank findings + eliminate dups • Best results with customization • No medical-specific metaseach tool • Example: Savvy Search • Guide to Metasearcher Tools

  46. What’s Out There? • the Good... • the Bad... • and the Ugly

  47. Evaluating Web Resources • Authority • Accuracy • Objectivity • Currency • Coverage Widener University Tutorial: Evaluating Web Resources

  48. Web ‘Treasure Hunt’ Find the AHCPR (NIH) Guidelines on Cardiac Rehabilitation (Full-Text!)

  49. Now that I’ve Got all this Info, What am I Suppose to Do with It? • Bibliographic Management Software • Provides mechanism to search for, download, store and retrieve citations • ‘Automatically’ creates reference lists and bibliographies • Examples: End Notes, Procite

  50. On the Internet… Content is King!
