Implicit intelligence beliefs of computer science students: Exploring change across the semester

This study investigated introductory computer science (CS1) students’ implicit beliefs of intelligence. Referencing Dweck and Leggett’s (1988) framework for implicit beliefs of intelligence, we examined how (1) students’ implicit beliefs changed over the course of a semester, (2) these changes differed as a function of course enrollment and students’ motivated self-regulated engagement profile, and (3) implicit beliefs predicted student learning based on standardized course grades and performance on a computational thinking knowledge test. For all students, there were significant increases in entity beliefs and significant decreases in incremental beliefs across the semester. However, examination of effect sizes suggests that significant findings for change across time were driven by changes in specific subpopulations of students. Moreover, results showed that students endorsed incremental belief more strongly than entity belief at both the beginning and end of the semester. Furthermore, the magnitude of changes differed based on students’ motivated self-regulated engagement profiles. Additionally, students’ achievement outcomes were weakly predicted by their implicit beliefs of intelligence. Finally, results showed that the relationship between changes in implicit intelligence beliefs and student achievement varied across different CS1 courses. Theoretical implications for implicit intelligence beliefs and recommendations for STEM educators are discussed.     

A review of Computer Science resources for learning and teaching with K-12 computing curricula: an Australian case study

To support teachers to implement Computer Science curricula into classrooms from the very first year of school, teachers, schools and organisations seek quality curriculum resources to support implementation and teacher professional development. Until now, many Computer Science resources and outreach initiatives have targeted K-12 school-age children, with the intention to engage children and increase interest, rather than to formally teach concepts and skills. What is the educational quality of existing Computer Science resources and to what extent are they suitable for classroom learning and teaching? In this paper, an assessment framework is presented to evaluate the quality of online Computer Science resources. Further, a semi-systematic review of available online Computer Science resources was conducted to evaluate resources available for classroom learning and teaching and to identify gaps in resource availability, using the Australian curriculum as a case study analysis. The findings reveal a predominance of quality resources, however, a number of critical gaps were identified. This paper provides recommendations and guidance for the development of new and supplementary resources and future research.

Cultivation of taste and bounded rationality: Some computer simulations

One can approach the economics of the arts, as any field of applied economics, in either of two ways. First, one can treat economic theory and econometric technique as subjects settled by specialists in those fields, to be used in the ec onomics of the arts as they are given, very much as if one were studying the demand for maize. Alternatively, one can treat the economics of the arts as a field which may need and suggest its own developments in theory and technique, suitable to its spec ial problems and processes, from which general economic theory and econometric theory might in principle learn something. Perhaps this latter view is implausible, given the high state of development of economic theory and econometrics in the modern liter ature. Yet many of the advances embodied in these fields have come from particular areas of application-and the economics of maize has been a particularly fertile field.I am indebted to participants in the Seventh International Conference on Cultural Economics, Fort Worth, Texas, October 1992; to p articipants in the Seminar on the Economics of the Arts, Venice, Italy, December 1992; to participants in the conference of the Pennsylvania Economists' Association, Wiles-Barre, PA, June, 1993; to participants in the second conference on Simulating Soci eties, Siena, Italy, July 1993; to participants in the conference of the Society for the Advancement of Behavioral Economics, Rensselaerville, NY, August 1993; and to participants in the Third Conference on Artificial Intelligence in Economics and Manage ment, Portland, OR, August 1993, for useful comments on topics related to the research reported in this paper.
