The document discusses how technology can be used as a "mindtool" to engage learners in critical thinking. It describes how learners can use simulations to navigate and manipulate virtual objects at their own pace. Visualization tools also allow students to share mental images of difficult to observe concepts and test hypotheses to build understanding. The document advocates for technology integration where students are in control of their learning, as opposed to technology solely being seen as the source of knowledge, to better prepare students for a global society.
