Many researchers and creativity psychologists have developed a number of instructional materials. In India Nirpharake, Deshmukh, Subramania Pillai, Bhaskara, Jerial and others have worked to foster the creative thinking abilities of students.Riddle construction: Children enjoy doing this activity of creative expression type, where they complete the half-finished riddle and write a full riddle for a given title or object or name.Riddles and puzzles are included in the EVS books just to develop critical thinking, curiosity and reasoning abilities in children.Riddle solving and riddle construction are similar to two principles of œSynectic, creativity fostering techniques developed abroad. They are making the strange familiar and making the familiar strange. Most of the riddles have been developed using analogies, which may be direct, simple, symbolic or fantasy.Characteristics of Riddles: Riddles provide the opportunity to think and learnRiddles helps to improve thinking ability and creativityRiddles are fun and also provide an opportunity to learnThis helps students to indulge in more readingRiddles helps to enhance vocabularyDevelop students for today and tomorrowRiddles create critical thinking and problem-solving skills which actually raise the IQ of studentsRiddles develops an effective learning skillHence, we conclude that to confuse the mind of the students and let them enjoy the confusion is not an objective of including riddles and puzzles in the EVS textbook.
