"‘I no longer feel that I need to know and do it all....that’s what colleagues are for... to share the responsibility for teaching our multilingual learners.’ This quote, from a seasoned educator, is at the heart of Margo Gottlieb’s and Andrea Honigsfeld’s new book. When it comes to student assessment, teacher candidates are taught to rely on standards and standardized testing, often at the cost of their own intuitive understanding of students and issues of equity, social justice, and cultural diversity – specifically multilingualism. Teachers need a new road map. The design of this book as a collaborative journey – complete with road signs, roadblocks, and yes, even pit-stops – is not only engaging, but mirrors teaching and learning as an interactive and on-going process. The belief that throughout this journey we must have multiple opportunities to meet-up with and collaborate with our colleagues, makes me eager to go on this journey along with my students."
