<p>After months of observing, reading, listening, interviewing, and participating in the life at Grand Rapids Child Discovery Center, it became clear what makes this place different. Simply put, it is in the way children are viewed. At traditional schools, children are viewed as having a “tabula rasa.” &nbsp;Contrary to that, GRCDC embraces in the Reggio inspired Image of the Child view where children are viewed as competent, curious, full of knowledge, and potential. They have rights, a voice and are taken seriously. They are not taught what to think; &nbsp;rather, they are encouraged and nurtured to learn how to think. &nbsp; Creation, innovation, and construction are all activities that are central to the guiding principles of the Reggio Emilia approach to education. &nbsp;One teacher remarked “We teach kids how to think. &nbsp;By using&nbsp;documentation, the Cycle of Inquiry, and other tools that follow the inquiry process with kids, they become big thinkers and curious wonderers. &nbsp;Essentially, we have thinkers here, not robots. &nbsp;They feel confident and strong.”</p>
<p>It is this view of children, the Image of the Child, that is at the heart of this school. This view acts a lens and things that one would normally assume about a school are refracted differently once children are viewed through it. The real power of the lens is that it is used so regularly and it is so widely endorsed by teachers, students and parents at GRCDC. Due to those factors, the lens acts as central force from the inside out, which then affects the classrooms, the overall school environment and the greater support system. As depicted in the diagram above, the Image of the Child serves as a central force that guides everything from big to little things in the ecosystem such as the role of teachers, the conversations, the curriculum, and even the types of materials present in the classroom. In addition to the interior force at work, the exterior forces at work are the <a title="Current Educational Environment" href="https://web.archive.org/web/20150926030537/http://www.rediscoveringschoolandcommunity.com/the-school/current-educational-environment/">Current Educational Environment</a> and the <a title="Organizational History" href="https://web.archive.org/web/20150926030537/http://www.rediscoveringschoolandcommunity.com/the-school/organizational-history/">Organizational History</a>.</p>
<p>*It should be noted that one can easily make the comparison to Bronfenbrenner’s Theory of Ecological Systems Theory, which is a natural connection because his theory does inform Reggio practice (refer to <a title="Reggio Resources" href="https://web.archive.org/web/20150926030537/http://www.rediscoveringschoolandcommunity.com/the-basics/reggio-resources/">The Basics: Reggio Resources</a> for more information). But this graphic was produced for this specifically for this project and it belongs to the Grand Rapids Child Discovery Center.</p>

有没有办法用jQuery强制所有元素上的悬停状态，以便一次显示所有alt文本？

我尝试使用$('area').trigger('mouseover');无效。
