The development of critical thinking skills is a fundamental educational objective necessary for Higher Education. Students in Higher Education are expected to engage in complex reasoning and analysis activities; therefore, they need to be taught how to think rather than what to think. Critical thinking allows learners to develop the ability to demonstrate their thinking processes and to make reasoned judgment about everything they learn. It also helps students be active participants in the learning process and prepares them to be lifelong learners who are capable of facing challenges. This book emphasizes the importance of integrating critical thinking in Higher Education, and it shares the findings of a research study that was conducted in order to investigate attitudes of university teachers and students towards the appropriateness and the implementation of critical thinking in Moroccan Higher Education. The book is likely to interest researchers in Higher Education, and English Language Teaching & Learning. The findings of the study might be of use to university teachers and students. However, given the importance of the topic, the work might also interest general readership.
