How the instructional and learning environments of liberal arts colleges enhance cognitive development

This study analyzes longitudinal data from 17 four-year institutions in the United States to determine how the distinctive instructional and learning environment of American liberal arts colleges accounts for the positive impact of liberal arts college attendance on four-year growth in critical thinking skills and need for cognition. We find that, net of important confounding influences, attending an American liberal arts college (vs. a research university or a regional institution in the United States) increases one’s overall exposure to clear and organized classroom instruction and enhances one’s use of deep approaches to learning. In turn, clear and organized classroom instruction and deep approaches to learning tend to facilitate growth in both critical thinking and need for cognition—thus indirectly transmitting the impact of attending a liberal arts college.

Is differential exposure to college linked to the development of critical thinking?

This study investigated the influence on critical thinking of differential exposure to postsecondary education. The sample was 2,076 first-year students attending 13 four-year and 4 two-year institutions from around the country. First-year students attending college full-time developed a higher level of critical thinking skills than those attending part-time. In the presence of controls for precollege critical thinking and academic motivation, the average critical thinking of first-year students at the institution attended, gender, race, age, and kinds of courses taken, the number of semester hours for which the student was enrolled had modest but significant positive effects on end-of-first-year critical thinking for both the two- and four-year college samples. In the two-year, but not the four-year, sample the relationship between semester hours and critical thinking deviated significantly from linearity. Students attending a two-year college full-time still derived the largest critical thinking benefits. However, the lowest levels of critical thinking accrued to those enrolled between 7 and 20 semester hours. Students enrolled for 6 or less hours actually had somewhat higher end-of-first-year critical thinking.     

Constructivism,the psychology of learning,and the nature of mathematics: Some critical issues

Constructivism is one of the central philosophies of research in the psychology of mathematics education. However, there is a danger in the ambiguous and at times uncritical references to it. This paper critically reviews the constructivism of Piaget and Glasersfeld, and attempts to distinguish some of the the psychological, educational and epistemological consequences of their theories, including their implications for the philosophy of mathematics. Finally, the notion of cognizing subject and its relation to the social context is examined critically.
