I have created two different types of quizzes to assess the mastery level of the uses of Ser and Estar (to be). The first quiz is a true or false assessment type. I created this quiz using Socrative. Socrative is an easy-to-use tool tool for building quizzes and seeing student results in real time. It also allows teachers to collaborate and share quizzes. My quiz number is SOC #: 15868778. It can be located at http://www.socrative.com/ (Room: RYQG5HEH).
My second portable learning object is a multiple choice quiz created using ClassTools. This is a fun, interactive Web 2.0 tool that allows students to play a game when they answer correctly the quiz questions.
