There is a general consensus that design-based research (DBR) is a genre of approaches in education research to design interventions for specific problems with the aim to gain an understanding of how they work in the problem context. While there is a considerable body of literature discussing the epistemic and methodological aspects of DBR, we…

The purpose of this study was to describe how US secondary science preservice teachers, or those preparing to teach middle and high school science, at one university, perceive engineering and teaching engineering within an epistemological framework of required domain components pre- and post-instruction (intervention) as well as over three cohort…

Preparing students to be competitive in the 21st century global economy is undoubtedly one of the major goals of all educators. Studies have shown that students who have an increased exposure to engaging STEM courses at the high school level are more likely to enter STEM majors at the collegiate level and, thus, STEM industries post-graduation…

For the forty-fourth time, the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented online and onsite during the annual AECT Convention. Volume 1 contains papers dealing primarily with research and development topics. Papers dealing with…

This study examined preservice teachers' problem-solving skills through the use of an online video case study. Eighty preservice teachers participated in the study with a three-level video presentation by a two-grade-level between-subjects factorial design. The study incorporates a content analysis framework to examine both the components and the…

Creativity is socially constructed and is not an objective fact at all. How do teachers perceive students' creativity and how can they foster students' creative learning? From two case studies, one in higher education and a second on iPad-classrooms in schools, the paper reflects on didactical concepts for creativity using mobile devices.…

Discusses two controversies regarding instruction in critical-thinking: (1) definitions of critical-thinking skills; and (2) the design of instructional delivery systems that promote the generalized use of these skills. Suggests that teachers select specific skills to teach and define those skills with clear, objective descriptions based on overt…

Instructional design strategy for improving problem solving is presented. The strategy entails selecting an appropriate domain of problem-solving tasks, learning hierarchies, teaching methods and assembling of learning materials, and designing teacher training and evaluation. Obstacles to be overcome and directions for future research are…

Discussion of the diffusion of interactive communications innovations focuses on the integration of telecomputing tools into precollege curricula. Topics include the telecomputing teacher as instructional designer; a models approach to instructional design; and telecomputing activity structures, including interpersonal exchanges, information…

Analyzes the cognitive processes and kinds of knowledge needed to work in a scientific domain like physics. Discusses the processes needed to interpret scientific concepts, uses of quantitative and qualitative descriptions, hierarchical ways of organizing scientific knowledge, and processes facilitating problem solving. Describes the use of these…

Discusses the rationale, aims, and objectives of introductory computer courses and suggests an improved approach to designing such courses to prepare pupils for a computer-based society and to improve problem solving through structured programing. Criteria for evaluating and choosing an appropriate programing language are listed. (EAO)

Discusses cognitive processes associated with mental rotation and procedures for presenting and learning orthographic projection. Descriptions include a series of three experiments generated by cognitive load theory that investigated the effects of worked example formats on high school students using two- and three-dimensional representations. (19…

Describes an instructional model for teaching abstract data types (ADTs) to high school students. Presents research results regarding students' conceptualizations of ADTs and their strategies of using them in computer science problem solving. To implement the ADTs, "black boxes" were used. (AEF)

Robert Gagne's model as presented in "The Conditions of Learning" (1970) is modified, extended, and used to form a logical model applicable to planning and teaching the social studies. It is used to develop planning procedures and to sequence instructional activities consistent with attaining complex levels of student learning. Sample…

Reports investigation of the first phase of problem solving, i.e., the awareness of mental operations, which uses cognitive process instruction to focus student attention on their thinking processes. Evaluation of students' ability to recall componential operations involved in familiar tasks indicates improvement in problem solving is an…
