As children age, their abilities vary greatly across many aspects of life functioning (Robbins, Chaterjee, & Canda, 2012, p. 260-296). One aspect of functioning is that of moral reasoning. Throughout childhood, moral skills develop in relationships with others and their environment. Moral development has been a popular topic of study for many years. Some theorists have developed tools to measure moral functioning. In order to know the accuracy of these tools, experiments must be designed and implemented to test the hypotheses and results. Much research has been done over the years on how children develop morally. Moral development has been identified as a person's sense of right and wrong and their ways of responding to ethical dilemmas (Tichy, Johnson, Johnson, & Roseth, 2010). There are many different goals when it comes to moral development. Some examples of this variance can be found in studies such as Tichy, Johnson, Johnson, and Roseth's (2010) study of constructive controversy and moral development, Stifter, Cipriano, Conway, and Kelleher's (2009) study. on temperament and moral development, the study of Passini. (2010) study of culture and moral development, and Levenson's (2009) study of gender and moral development. Although these researchers all play important roles in the study of moral development, the theorist most often associated with the topic is Lawrence Kohlberg (Robbins, Chaterjee, & Canda, 2012, pp. 277-280). Lawrence Kohlberg made many discoveries involving children's moral development through extensive research (Robbins, Chaterjee, & Canda, 2012, p. 260-296). Kohlberg (1969) suggests that children go through unique stages of moral development...... middle of article ......440.xRest, J., Turiel, E., & Kohlberg, L. (1969 ).
