This research develops a web-based model, entitled the "intuitive claim, peer-assessment, discussion, and elaborate claim argumentation training" (IPadE) model, and embeds with a Web-based Interactive Argumentation System to enhance undergraduate students' socioscientific argumentation abilities. This research adopts a quasi-experimental research design; the sample comprised 131 undergraduate students from two classes (69 in the experimental group and 62 in the control group). The socioscientific issue discussed were related to global health. This study collected and analysed quantitative and qualitative data, including the pretest and posttest of students' knowledge test scores and argumentation abilities questionnaire. The results generally confirmed the effectiveness of the IPadE model. First, in a comparison of the content knowledge and argumentation skills, the experimental group have statistically significantly improved than the control group. Second, regarding the number of reasoning modes proposed, the experimental group could propose multiple reasoning modes and reasoning levels on rebuttals increased after training.

This research investigates the effect of a web-based model, named "Practicing, Reflecting, and Revising with Web-based Assessment and Test Analysis system (P2R-WATA) Assessment Literacy Development Model," on enhancing assessment knowledge and perspectives of secondary in-service teachers, and adopts a single group experimental research design. The WATA system provides teachers with personalized learning resources and situated environment to practice assembling, administering tests on-line, and appraising test-related statistical information to reflect and revise test items. The sample consisted of forty-seven secondary in-service mathematics and science teachers in a summer program for 36 h within six weeks. This research collects and analyzes quantitative data, including the pre-test and post-test of teachers' knowledge and perspectives on assessment. The major results generally confirm the effectiveness of P2R-WATA model. Firstly, the assessment knowledge of the participants has improved after training, especially for teachers with low-level prior knowledge. Secondly, the findings also reveal that there is a significant improvement on teachers' assessment perspectives. (Contains 7 tables and 11 figures.)
