Title: The UC-WISE Project: Online curricula for monitored, closed-lab first-year CS courses


1
The UC-WISE Project Online curricula for
monitored,closed-lab first-year CS courses
  • UC-WISE University of California Web-based
    Instruction for Science and Engineering
  • Project leadersMike Clancy (clancy_at_cs.berkeley.e
    du)Marcia Linn (mclinn_at_berkeley.edu)Nate
    Titterton (nate_at_socrates.berkeley.edu)

2
A UC-WISE course vs. a traditional-format course
  • Students attend 0-1 lecture hr/wk, 4-6 lab
    hrs/wk.
  • Students engage in online collaboration and
    impromptu face-to-face discussions with neighbors
    or staff.
  • Most work is done in super-vised lab context is
    clear from earlier exercises help is always
    available in lab.
  • Staff monitors activities, engaging students in
    timely tutoring if necessary.
  • Students attend 2-3 lecture hrs/wk, 2 lab hrs/wk.
  • Students attend a weekly discussion section.
  • Homework is unsupervised students may not be
    clear about skills/techniques to use help is
    harder to get.
  • Students may be unaware of misunderstandings, and
    may wait weeks to address them.

3
Lab-based course logistics
  • Activities are all online, presented in a custom
    course portal.
  • Lab sections each contain around 25 students and
    are each staffed by an instructor and 1-3 lab
    assistants.

4
Lab activities
Increased lab time allows activities to be
organized in relatively small conceptual steps
  • Web page reading
  • quizzes and self-assessments
  • online focused discussion
  • gated collaborations
  • face-to-face collaboration
  • online note-taking
  • programming
  • constrained interactive programming tasks

5
Benefits to students
  • Replacement of lecture with lab
  • More work, but less bogging down
  • Small steps from activity to activity
  • Frequent embedded assessments
  • Just-in-time targeted tutoring
  • More efficient interaction with staff
  • Flexible pacing
  • Collaboration among students
  • Engagement of traditionally underserved groups

6
Benefits to instructors
  • Easy modification of the curriculum
  • Exposure of student misconceptions
  • Less lecturing, but more staff training,
    curriculum tuning, or review of student work
  • Better focus for lectures

7
UC-WISE courses so far
  • Introduction to Symbolic Programming (intro for
    nonmajors) at Berkeley
  • Data Structures and Programming Methodology
    (essentially CS 2) at Berkeley
  • Introduction to Computing for Engineers (intro
    for sci/eng) at Berkeley
  • Introduction to Computing I (intro for sci/eng)
    at Merced
  • Introduction to Computer Science and
    Engineering (CS 1.5) at Merced

8
CCLI-funded work
  • Lab-based UC-WISE curricula for CS 1 and CS 2
    courses using Java
  • Collaboration with colleagues at U.C. Merced,
    U.C. Irvine, and U.C. San Diego

9
Future work tools
  • For the instructor better monitoring of student
    progress
  • For students better curriculum access, toolkits
    for interactive programming pages, collaborative
    toolkit
  • For curriculum designers Learning Object
    repository, metadata definition and browsing
    facilities, course builder thats integrated
    with a library of pedagogical patterns

10
Future work educational research
  • Research on synchronicity and on value added by
    new activities (discussion, gated collaboration)
  • Comparison of online vs. face-to-face
    collaboration
  • Exploration of differential performance of groups
    traditionally underrepresented in CS
  • Research on various kinds of immediate feedback
  • Evaluation, evaluation, evaluation interviews
    and surveys

11
For further information ...
  • New Roles for Students, Instructors, and
    Computers in a Lab-based Introductory Programming
    Course (SIGCSE 2003) reports initial experience
    with lab-based courses using the UC-WISE system.
