Reinventing learning: a design-research odyssey

Design research is a broad, practice-based approach to investigating problems of education. This approach can catalyze the development of learning theory by fostering opportunities for transformational change in scholars’ interpretation of instructional interactions. Surveying a succession of design-research projects, I explain how challenges in understanding students’ behaviors promoted my own recapitulation of a historical evolution in educators’ conceptualizations of learning—Romantic, Progressivist, and Synthetic (Schön, Intuitive thinking? A metaphor underlying some ideas of educational reform (working paper 8). Division for Study and Research in Education, MIT, Cambridge, 1981)—and beyond to a proposed Systemic view. In reflection, I consider methodological adaptations to design-research practice that may enhance its contributions in accord with its objectives

The effect of a semester unit of study on ethical issues in nursing on a group of practising registered nurses

This study explored the effect an educational unit on ethical issues in nursing had on the ethical reasoning of practising registered nurses. The educational unit was conducted at a university school of nursing as part of a baccalaureate degree programme for already registered and practising nurses. A quasi-experimental posttest design utilising stratified random samples compared subjects from one group who had undertaken the unit (n=53) with subjects from another group who had not (n=61). Ethical reasoning was measured using Grisham\u27s Nursing Dilemma Test and a researcher designed demographic data sheet provided information on additional variables for analysis.The group which had undertaken the unit had a significantly higher principled thinking score at n=.05. There were no other significant findings for other variables. The result is discussed in relation to other research findings, various extraneous variables and theoretical and measurement issues

Success in tutoring electronic troubleshooting

Two years ago Dr. Sherrie Gott of the Air Force Human Resources Laboratory described an avionics troubleshooting tutor being developed under the Basic Job Skills Research Program. The tutor, known as Sherlock, is directed at teaching the diagnostic procedures necessary to investigate complex test equipment used to maintain F-15 fighter aircraft. Since Dr. Gott's presentation in 1987, the tutor has undergone field testing at two Air Force F-15 flying wings. The results of the field test showed that after an average of 20 hours on the tutor, the 16 airmen in the experimental group (who average 28 months of experience) showed significant performance gains when compared to a control group (having a mean experience level of 37 months) who continued participating in the existing on-the-job training program. Troubleshooting performance of the tutored group approached the level of proficiency of highly experienced airmen (averaging approximately 114 months of experience), and these performance gains were confirmed in delayed testing six months following the intervention. The tutor is currently undergoing a hardware and software conversion form a Xerox Lisp environment to a PC-based environment using an object-oriented programming language. Summarized here are the results of the successful field test. The focus is on: (1) the instructional features that contributed to Sherlock's success; and (2) the implementation of these features in the PC-based version of the avionics troubleshooting tutor

Design Early Considered Harmful: Graduated Exposure to Complexity and Structure Based on Levels of Cognitive Development

We have recognized that the natural tendency to teach according to the structure of one’s own understanding runs contrary to established models of cognitive development. Bloom’s Taxonomy has provided a basis for establishing a more efficacious pedagogy. Emphasizing a hierarchical progression of skill sets and gradual learning through example, our approach advocates teaching software development from the inside/out rather than beginning with either console apps or monolithic designs

Introductory Programming and the Didactic Triangle

In this paper, we use Kansanen's didactic triangle to structure and analyse research on the teaching and learning of programming. Students, teachers and course content are the three entities that form the corners of the didactic triangle. The edges of the triangle represent the relationships between these three entities. We argue that many computing educators and computing education researchers operate from within narrow views of the didactic triangle. For example, computing educators often teach programming based on how they relate to the computer, and not how the students relate to the computer. We conclude that, while research that focuses on the corners of the didactic triangle is sometimes appropriate, there needs to be more research that focuses on the edges of the triangle, and more research that studies the entire didactic triangle. © 2010, Australian Computer Society, Inc

Developmental education and teacher training

This study was designed to investigate the relationship of cognitive development and moral development; the differences and similarities between prospective elementary teachers and prospective secondary teachers in stages of cognitive development and moral development; as well as the relations between levels of cognitive and moral development and chronological age, experiences in mathematics, experiences in science, grade point average, and SAT scores. Forty-three prospective elementary teachers and 32 prospective secondary teachers were administered Piagetian cognitive and Kohlbergian moral dilemma tests in order to determine their levels of cognitive development and moral development, respectively. The Piagetian type test consisted of a proportional test and quantification of probabilities test. The data obtained were analyzed, by computer, using the t-statistic and Pearson-Product-Moment correlation coefficients
