Self-concept is broadly defined as a person’s perceptions of himself or herself. Self-concept is one of the most extensively researched constructs in educational psychology. This book provides new research, perceptions, cultural influences and gender differences of self-concept. Chapter One discusses a process called fusion which states that various constructs may be perceived to be more or less integrated within the self-concept. Chapter Two focuses on academic self-concept and its correlation to academic achievement. Chapter Three analyses the different relationships among self-beliefs, metacognition and mathematics achievement in Japan, mainland China, Singapore, South Korea, Taiwan and the United States. Chapter Four derives a structural model for the multidimensional self-concept construct. Chapter Five examines how a belief system of a Chinese student, who is a learner of Japanese as a foreign language, impacts on his self-concept as a foreign language learner. Chapter Six assesses how sport and exercise psychology textbook authors portray disability to readers.
