  1. Thinklets Integrating Java into the Curriculum Bert G. Wachsmuth Seton Hall University

  2. Seton Hall University • Catholic University in New Jersey, next to New York City • 10,000 students total • 4,500 Undergraduate students • Mission: “…to prepare students to be servant leaders who will make a difference in the world …” • In short: mid-size, private college with high degree of Information Technology

  3. Information Technology at SHU • On of the top 30 Most Wired Campuses nationwide • Mobile Computing Program (5,000 laptops on 2-year leases for UG students and faculty) • Wireless Campus • State-of-the-Art Gigabit backbone • Reasonable Internet, (soon) Internet 2 connectivity • Extensive buy-in by upper administration • 5 year strategic plan implemented, second strategic plan approved • Approximately 10% of University Budget

  4. Support for Teaching/Learning • Extensive Blackboard use (every class automatically available and populated) • Teaching, Learning, and Technology Center (also Telecom, Media Center, Networking, PC Support) • (almost) 24 x 7 Help Desk and Laptop repair • Reasonable technology Assessment implementation • Extensive Software Package (Office, FrontPage + Server Extensions, SPSS, Maple, Notes, etc.)

  5. Pilot Projects and Grants • CDI: Curriculum Development Initiative(Multi-year technology grants to maximize impact on students) • FIG: Faculty Innovation Grants(Small grants to support individual faculty projects) • Lila: Linux Laptops(Dual-Boot Windows and Linux Laptop with functionally equivalent software for both OS) • SHUTAP: SHU Tablet PC’s(Investigate potential impact of Tablet PC’s on Teaching and Learning)

  6. So, what’s missing? JAXP? WSDL? WSRP? BPEL? JSR? WS-I? MEP? Certainly - but I want to focus on …

  7. Thinklets • A Thinklet is a small, focused program that runs inside a web browser and helps visualize or utilize concepts in areas useful for academic disciplines • Thinklets are developed "in house" as cooperation between a content specialist (faculty), one or more student programmer(s), and a coordinator. • Thinklets are available for free for educational institutions; source code is available upon request • What was missing: create not only consume

  8. Stand-alone Thinklets • PopDynamics: illustrates predator-prey relationships (biology, dynamical systems) • Sorting: illustrates/compares many sorting algorithms (computer science) • FFT: shows how analog signals are decomposed as Fourier Series (math, networking) • HypoTester: illustrates how hypothesis testing works (statistics)

  9. General Purpose Thinklets • SyncStream: lets you create slideshows that are synchronized with a Real video stream. Comes with a stand-alone editor and an (independent) SyncStream applet. Does not require special server software • Jadis: A dictionary program that can help translate web pages and lets you upload “translated” web pages. Several dictionaries available (of varying quality)

  10. Integrated Thinklets • IRA: An online text book on Real Analysis (Advanced Calculus) that integrates several Thinklets into a coherent, large-scale project • PsychoQuiz: An applet that uses JDBC technology to test student’s knowledge of standard terminology in experiment design and hypothesis testing. It is integrated into a large-scale course re-design project in Psychology.

  11. Thinklets with Servers • Asset: A Servlets-based project to create, deliver, and evaluate web-based surveys. Can also be used as a voting tool with LDAP-verified voter lists. • ChatterBox: A complete client/server chat solution with features such as password protected rooms, auditorium mode, web page pushing, etc.

  12. Thinklets with Maple (supported by a grant from Waterloo Maple) • JCalc: Maple with a custom-made user interface for mathematics up to Calc 3 • JGJ: Learn how to solve a system of Linear Equations or to invert a square matrix • ZMap: Visualize the (4-dimensional) graph of a complex function

  13. Thinklets Framework • Student Programmer: • Most Thinklets are created by, or with the help of, one or more student. • Content Specialist: • Most Thinklets are created with the help of, or with ideas from, a faculty member. • Coordinator: • Analyzes faculty suggestions for feasibility, moderates content/programmer interaction, and helps with programming aspects • Resources Required: • Supported by TLTC money and external grants • Close cooperation with Comp. Sci. department to find student programmers • Requires 1 Intel-based multi-processor Linux server and some cooperation from IT professional department

  14. Thinklet Advantages • “Low-tech” and focused: can create a “small” Thinklet in about 2 months • No competition with “professional” IT developers • Benefit for Student Programmer: • interesting on-campus job • portfolio piece • integrating software into larger project • Benefit for Faculty: • relatively quick turn-around time • cheap • easy “presentation material” • Benefit for Coordinator: • Gets to travel to Florida in the Winter

  15. Thinklet Successes • Asset – widely used at Seton Hall and other institutions (and presented at JA-SIG 2002) • ChatterBox – frequently requested by small web site operators • Jadis – presented at Russian Language Conference • SyncStream – written up in the “Chronicle” • PopDynamics – presented at “Biology and IT” conference • IRA Thinklets – several thousand people signed guestbook • Jobs – all programmers who worked on Thinklets and graduated got decent jobs.

  16. Thinklet Failures • Unclear Concept: Trig FunctionsIf it is not immediately clear how a Thinklet works and what it is supposed to illustrate, it fails. • Too Simplistic: Projectile MotionIf the concept a Thinklet illustrates is so simple that students understand it already, it fails. • No support: PsychoQuizIf a Thinklet requires extensive user support but the original collaborators are not committed or unavailable, it fails. • External Reliance: SyncStream Support to maintain Thinklets is minimal. If a Thinklet relies on external technology that is too complex or changes too quickly, it fails.

  18. Thinklet Contributors • Brian Borowski • Michael Bosco • William Daly • Patrick Fineza • Paul Ladny • Brad Lepre • Rehan Malik • Robert Moore • Steve O'Brien • Joseph P. Ptaszynski • Sam Shiffmann • Bert G. Wachsmuth • Huang Shon Wen (Sam) (Thinklets existed from about 2000 – now)
