Introduction Motive Web-SPA PFSPA Experiment Conclusion Comment
3
Introduction – 1/2
teacher-assessment self-assessment
– self-reflection and self-stimulation peer-assessment
– active learning, social interaction, self-monitoring and regulation
4
Introduction – 2/2
traditional method– many restrictions
multimedia works recording and compiling time
web-based method– any time and any where– real time– high-speed compute
5
Motive
constraints of the arrangement in other systems
advantage of web-based method reduce the workload enhance the efficiency of executing
propose Web-SPA & PFSPA procedures
6
web-based self- and peer-assessment system
provide flexible interface main modules
– user interface– web server application program module– database server
Web-SPA - 1/3

Web-SPA - 2/3

PFSPA – 1/5
progressively focused self- and peer-assessment
characteristics of the PFSPA– recurring of the activities of self-assessment– increasingly sharp contrast– seeks a balance between the evaluating works
and the economy of time allocation
10
traditional procedures– Each and every student assesses his own work– Peer-assessing or re-assessing– Examining/discussing the within-group peer-
assessment results– Examining/discussing the results of peer
assessments among groups– Discussion among groups
PFSPA – 2/5
11
PFSPA procedures– Stage 1: within-group members individuall
y observed and evaluated the works of each other
– Stage 2: conducting the second-stage assessments (best and poorest works)
– Stage 3: conducting the best and the poorest works (one for each)
PFSPA – 3/5

PFSPA – 4/5

PFSPA – 5/5

Experiment – 1/4
Participants– 76 third-graders in a junior high school
2 classes of 37 and 39 students 43 were male and 33 female
Requirement– using individual works– using the percentage scoring scheme and text commentary– anonymous– repeated progressive assessments
15
decrease the discrepancy assessments between students and experts
reduce workload of assessor students greater objectivity in their self-assessment s
cores quality of the students works improved after the asse
ssment activities discover consistency of assessment results between
the students and teachers
