Science Teachers’ Use of Visual Representations by Billie Eilam, John K. Gilbert

By Billie Eilam, John K. Gilbert

This e-book examines the varied use of visible representations through academics within the technological know-how lecture room. It comprises detailed pedagogies with regards to using visualization, offers unique curriculum fabrics in addition to explores destiny possibilities.

The ebook starts off via the importance of visible representations within the instructing of technological know-how. It then is going directly to aspect contemporary techniques within the box: simulations and slowmation, a technique of particular visualization. It additionally evaluates the best way lecturers have used assorted diagrams to demonstrate suggestions in biology and chemistry.

Next, the booklet explores using visible representations in culturally assorted school rooms, together with the implication of tradition for lecturers’ use of representations, the an important value of language within the layout and use of visualizations and visualizations in renowned books approximately chemistry. It additionally indicates where of visualizations within the turning out to be use of casual, self-directed technological know-how education.

Overall, the booklet concludes that if the possibility of visualizations in technological know-how schooling is to be learned sooner or later, the topic needs to be integrated in either pre-service and in-service instructor schooling. It explores how you can advance technological know-how academics’ representational competence and information the impression that this can have on their teaching.

The around the globe pattern in the direction of delivering technological know-how schooling for all, coupled with the elevated availability of colour printing, entry to private desktops and projection amenities, has bring about a extra vast and numerous use of visible representations within the lecture room. This e-book deals targeted insights into the connection among visible representations and technology schooling, making it an awesome source for educators in addition to researchers in technology schooling, visualization and pedagogy.

However, we also emphasized that in addition to benefits, different VRs or some of their properties may constraint learning in diverse ways. Another point is that the quality of teaching and learning is not determined by the VRs used and their properties alone; it is the result of complex interactions between teachers’ and teaching approaches, students’ characteristics – their knowledge, beliefs and relevant skills, the characteristics of the learning materials – including the content, tasks, and VRs, and the wider milieu – like cultural background.

Simulations represent and imitate the chaotic and ambiguous environment of the real world, based on a constructed model of it. By performing explorative interaction with simulations, learners are able to test and visualize their hypotheses, develop models about the system, modify them and establish relations among variables. It also enable them to experience skills like, planning, testing, analyzing, and critiquing models, while engaging in multivariable reasoning like, controlling variables, identifying causal relations, explaining simultaneous effects of multiple variables.

In terms of what the six teachers considered less useful, a paper describing textbook design and how it has changed over time was almost universally judged as uninteresting. Rationales for placing this as least useful were that it did not address whether some designs were more effective than others, did not tell them anything surprising (“its just common sense”) but also for two teachers they no longer (or rarely) used commercially published textbooks preferring to develop their own materials. Two further papers ranked almost equally low but for very different reasons.
