The purpose of this study was to evaluate the BASICS program. The program, Building and Applying Strategies for Initial Cognitive Skills, was developed by the Institute for Staff Development of Miami, Florida, for educating teachers, paraprofessionals, and parents in techniques considered essential in helping pre-school, primary grade, and special education children develop initial cognitive skills. The study was undertaken to determine the effects of the program on the self-concept, experimental beliefs, dogmatism, and pupil control ideology of in-service elementary school teachers who participated in it as an elective graduate level course. The design of the study was the non-equivalent control group design. Twelve subjects who volunteered to participate in the program formed the experimental group. Twelve other subjects were randomly selected from a graduate-level class in elementary school curriculum development to form the control group. The instructor who was in charge of the BASICS program taught the class from which the control subjects were selected. The study was conducted during the first six-week summer term of 1975 at North Texas State University. The two groups were administered pre and post the Tennessee Self Concept Scale, the Personal Beliefs Inventory (PBI), the Teacher Practices Inventory (TPI), the Dogmatism Scale Form E, and the Pupil Control Ideology (PCI) Form. The pre- and post-test data obtained were analyzed using the Mann-Whitney U as a one-tailed test.

Utilizing ECLS-K:2011 data, this study compares adopted and biological children to account for the role of heritable characteristics in explaining the relationship between family environments and children's cognitive skills. I find that cognitive skills do not differ across adopted and biological children after adjusting for the systematic differences between them. I also find that the relationship between family environment and children's cognitive skills does not differ across adopted and biological children. Taken together, these results suggest that the relationship between family environment and children's cognitive skills is not spurious.
