Preface IMAX partners with schools, supporting them with learning materials and processes that are all crafted to work together as an interconnected system to drive learning. IMAX presents the latest version of the Summit series – specially crafted as an accompanying workbook series for the Maharashtra state board textbooks. The Summit series endeavours to be faithful to the spirit of the National Curriculum Framework (NCF) 2005 in conjunction with the content covered and approach adopted in the Maharashtra state board textbooks. The larger aim of the NCF 2005 regarding science teaching is to acknowledge and address the dynamic nature of science by focusing on the development of skills to acquire and process information scientifically. It also recommends the use of graphics, illustrations and pictures to help students to engage with concepts and ideas better. Below are some salient features of the Summit EVS-I workbooks series: Arrangement of questions based on the RUAH (Remember, Understand, Apply and Higher Order Thinking Skills) model based on Bloom’s Taxonomy Stimulating Application and Higher Order Thinking Skills (H.O.T.S.) questions that ensure students engage with the content and not just focus on rote learning Effective use of concept-maps to enable learning of structures, processes and phenomena Exposure to locally relevant environmental problem solving All textbook questions that require space for writing have been included Overall, the IMAX Summit series aims to enhance the development of scientific temper along with the inculcation of healthy habits, skills and values that promote environmentally sensitive and culturally responsive democratic citizenship among students. – The Authors 51704086_BGM_9789387848856_Summit G4 Environmental Studies 1 Workbook Part 1_Text_Revised.pdf 2 3/24/2018 11:33:32 AM
