A theory of instruction for introductory programming skills     

Benjamin Xie  Dastyni Loksa  Greg L. Nelson  Matthew J. Davidson  Dongsheng Dong  Harrison Kwik 《Computer Science Education》2019,29(2-3):205-253

ABSTRACT

Background and Context: Current introductory instruction fails to identify, structure, and sequence the many skills involved in programming.

Objective: We proposed a theory which identifies four distinct skills that novices learn incrementally. These skills are tracing, writing syntax, comprehending templates (reusable abstractions of programming knowledge), and writing code with templates. We theorized that explicit instruction of these skills decreases cognitive demand.

Method: We conducted an exploratory mixed-methods study and compared students’ exercise completion rates, error rates, ability to explain code, and engagement when learning to program. We compared material that reflects this theory to more traditional material that does not distinguish between skills.

Findings: Teaching skills incrementally resulted in improved completion rate on practice exercises, and decreased error rate and improved understanding of the post-test.

Implications: By structuring programming skills such that they can be taught explicitly and incrementally, we can inform instructional design and improve future research on understanding how novice programmers develop understanding.  相似文献   

Students' conceptions of natural selection and its role in evolution: Cases of replication and comparison     

Sherry S. Demastes  John Settlage  Ron Good 《科学教学研究杂志》1995,32(5):535-550

The work of Bishop and Anderson (1990) plays a major role in educators' understanding of evolution education. Their findings remind us that the majority of university students do not understand the process of evolution but that conceptual change instruction can be moderately effective in promoting the construction of a scientific understanding. The present article details two studies that represent an effort to focus on and define the limits of the Bishop and Anderson (1990) study. Study A describes a close replication of the work of Bishop and Anderson (1990) using the same conceptual-change teaching module to teach a unit on evolution to students enrolled in a biology course for nonmajors. Study B, a case of comparison, used the same evaluation instrument used in Bishop and Anderson (1990) and Study A, but high school students were the participants and the instruction was based on the inquiry approach to science. Like Bishop and Anderson (1990), Study A showed that the amount of prior instruction and students' beliefs in evolution were not found to be large factors in students' use of scientific conceptions. Unlike the original study, the students in Study A showed only a meager increase in their use of scientific conceptions for evolution. In Study B, students in the experimental group showed significant increases in their use of scientific conceptions. These findings suggest a need to investigate more closely the teachers' theories of learning, their reliance on instructional conversations, and the amount of time devoted to the topic of evolution as we study conceptual change in this area.  相似文献   

Salivary cortisol as a predictor of socioemotional adjustment during kindergarten: a prospective study   总被引：2，自引：0，他引：2  

Smider NA  Essex MJ  Kalin NH  Buss KA  Klein MH  Davidson RJ  Goldsmith HH 《Child development》2002,73(1):75-92

This study, based on a sample of 172 children, examined the relation between average afternoon salivary cortisol levels measured at home at age 4.5 years and socioemotional adjustment a year and a half later, as reported by mothers, fathers, and teachers. Cortisol levels were hypothesized to be positively associated with withdrawal-type behaviors (e.g., internalizing, social wariness) and inversely related to approach-type behaviors, both negative and positive (e.g., externalizing, school engagement). Higher cortisol levels at age 4.5 predicted more internalizing behavior and social wariness as reported by teachers and mothers, although child gender moderated the relation between cortisol and mother report measures. An inverse relation was found between boys' cortisol levels and father report of externalizing behavior. A marginal inverse relation was found between child cortisol levels and teacher report of school engagement. Behavior assessed concurrently with cortisol collection did not account for the prospective relations observed,suggesting that cortisol adds uniquely to an understanding of behavioral development.  相似文献   

Lifelong learning and the reform of the teaching practicum in Australia     

Ron Toomey Corresponding author  Judith Chapman  Janet Gaff  Jacqueline McGilp  Maureen Walsh  Elizabeth Warren 《Asia-Pacific Journal of Teacher Education》2005,33(1):23-34

This paper reports the findings of a project—‘Lifelong learning and teacher education’—undertaken by the Centre for Lifelong Learning, Australian Catholic University, under the auspices of the Australian Commonwealth Department of Education, Science and Training. The study was designed to investigate the operationalization of lifelong learning in Australian teacher education. The study revealed that there is a range of existing, innovative practices regarding partnerships between schools and higher and further education that are in keeping with emerging ideas about lifelong learning. Moreover, some of these take the form of collaborative action research projects focused on improving the learning occurring in the partnership schools. This paper describes some current approaches in Australia to collaborative action research by teacher educators' and their partnership schools and shows how they contribute to lifelong learning. The approaches are then analyzed to suggest ways of advancing lifelong learning within Australian Education Faculties thus helping to make lifelong learning more of a reality for all.  相似文献   

Opportunity structures and educational marginality: the post-16 transitions of young people outside education and employment     

Ron Thompson 《牛津教育评论》2017,43(6):749-766

This paper reports on findings from a three-year ethnographic study of 24 young people in northern England who were classified as not in education, employment or training (NEET), or at risk of becoming so. Drawing on conceptions of opportunity structure and educational marginality, the paper discusses the processes leading to young people becoming NEET after leaving school. It presents findings concerning the family backgrounds, school experiences, and educational attainment of participants, and traces their initial post-16 destinations and their pathways to NEET status. Although most participants did not become NEET immediately after leaving school, restricted labour market opportunities and a lack of high-quality education and training for middle- and low-attaining young people exacerbated social and educational disadvantage. Over time, participants became increasingly restricted to marginal forms of learning. The paper argues that a focus on opportunity structures provides a powerful way of understanding these processes, and that alongside sustained NEET status, educational marginality should be of equal concern to policy makers.  相似文献

Towards a theory of instruction in the 1980s     

Jenny L. Covill-Servo  Ron Hein 《Instructional Science》1983,12(4):301-319

The purpose of this article is to provide a historical perspective on the contributions of learning and instruction to instructional theory and to discuss some of the major obstacles currently inhibiting the growth of “Instructional Theory.” Some suggestions for future development of this discipline are provided. In clarifying the impediments to instructional theories' development, heavy reliance is placed upon the process of theory construction as perceived by philosophers of the natural and social sciences. Some comments are made regarding the appropriate use of instructional theory in developing nations.  相似文献
