This site provides a number of videos featuring a wide array of assessment issues: from the needs of today's students to using data from online assessments.
How do we assess students' learning in these in Web 2.0 environments? We want to go beyond assessing the mere mechanics of using these tools; unfortunately, most current rubrics for Web 2.0 learning devote only a minuscule amount (usually 16% or less) to actual student academic learning.
Effective 21st century assessment reaches beyond traditional testing to look at the broader accomplishments of learners. Assembling an e-portfolio, or electronic portfolio, is an excellent method for assessing students' progress toward school, state, or national academic standards, as well as 21st century skills. An electronic portfolio is a purposefully limited collection of student selected work over time that documents progress toward meeting the standards.
Many links to Web 2.0 resources are provided on this site: 100 Apps for Tech savvy teachers, Web Tools 4U2Use, Audio, books, File Sharing, and many-many more....
Talking about Web 2.0 tools and learning is meaningless as well - until you explain what the tools are, what they are used for, and what the students do with them.
