Easybib. ResearchReady is a priced product but there is a free web evaluation tool. You type in the URL of the website you want people to evaulate. It prompts them to answer some questions about how credible etc. they think it is (with the website in the left panel and the questions in a right panel). At the end you can email the results to an email of your choice. The idea is that you would tell learners to evaluate a website and then get your evaluation of that website emailed to you so you could assess how well the learner had done. The full priced product has tutorials, suggested exercises and assessments etc.
