What types of materials can be electrically charged? How does current flow in a circuit? Will a magnet pick up any kind of metal? In answering these types of questions, children will reveal their own preconceptions about ideas that they bring with them into the learning environment. Their teachers need ways to help them identify misunderstandings that may occur during instruction. That’s why probes are an essential component in the science teacher’s toolkit.
Page Keeley and Rand Harrington, in their book, 39 NEW Electricity and Magnetism Formative Assessment Probes (Vol. 2 in the Uncovering Student Ideas in Physical Science series), bring K-12 teachers a whole new collection of carefully researched and developed probes around electric or magnetic phenomena or concepts.
Designed to be used as formative, rather than summative assessments, these intellectually engaging probes are designed to “stimulate student thinking and involve students in productive discussions as they grapple with their own ideas and consider the ideas of others.” The feedback gleaned from each question provides non-judgmental, valuable feedback to both educators and students in grades 3-12.
The book organizes 39 probes into three sections: Electric Charge; Electric Current; and Magnets and Electromagnetism—with each section starting off with a concept matrix identifying the main concepts related to the probe and the suggested grade level for each. Related ideas from the 2009 updated version of the Benchmarks for Science Literacy and links to the Next Generation Science Standards are included as well as related NSTA resources, such as books, journal articles, and collections from NSTA’s Learning Center.
Teachers will appreciate that each probe starts off with a question and a series of responses from which students can choose—with the related expectation that students will explain their thinking on the answer they selected (such as what rule or reasoning did they use in making their predication). Each probe is accompanied by teacher background notes—critical components for educators to explore/examine prior to using each probe—that cover the following areas:
Keeley and Harrington, in their introduction, acknowledge that “we are surrounded daily by the phenomenon produced by electric charge—these charges are what makes things work, including all the electronic devices we own.… Yet most of us have only a vague notion of what electric charge is and even less of an understanding of where these charges come from, where they go and how they move around.”
Happy Uncovering in this easy-to-read (you don’t need to be a science specialist to understand the contents!) resource!
This book is also available as an e-book.
