Study Notes
Preface
- The educational landscape in India is shifting towards competency-based education.
- Competency-based learning emphasizes critical thinking and problem-solving.
- CISCE has developed competency-focused practice questions for ICSE Class X Chemistry to build these skills.
- The questions are designed to help teachers develop their own competency-focused question bank and to help students prepare for higher-order thinking questions in future examinations.
- The questions cover understanding, analysis, application, evaluation, and creativity. Some also include higher-order recall.
Table of Contents
- The document contains practice questions categorized by question type.
- The questions are organized into Multiple-Choice, Fill-in-the-Blanks, Match the Following, One-Word, Structural Diagram, IUPAC Names, Very Short Answer, Short Answer, and Long Answer questions.
- Page numbers are included to help navigate to specific question sections.
Chemistry Practice Questions
- The document provides a set of practice questions covering topics in Chemistry for ICSE Class X.
- Each question includes the domain of the cognitive learning domain addressed by that particular question.
- Sample questions are available from various chapters in the subject.
- Sample questions are given, and the solutions are also provided at the end of the book.
