The foundation of geometric knowledge and understanding starts in primary school, and in contemporary mathematics education there is an emphasis on identifying learning progressions and trajectories as a way of moving students forward. The van Hiele (1986) theory is well-documented and provides insights into the progression and differences of…

Supporting elementary student understandings of ideas related to Earth's Place in the Universe (ESS1) can be challenging, especially given the large time and distance scales involved with many of the concepts. However, with effective use of crosscutting concepts and science and engineering practices, important concepts within this content domain…

Space has fascinated and intrigued humans of all ages since time immemorial, and continues to do so today. The natural curiosity is engaged when looking up into the sky, notice patterns among celestial objects such as the Sun, Moon, and stars, and wonder. Scientific understanding of those patterns has progressed immensely over the span of human…

We developed a two-semester series of intensive (six-contact hours per week) behavioral research methods courses with an integrated statistics curriculum. Our approach includes the use of team-based learning, authentic projects, and Excel and SPSS. We assessed the effectiveness of our approach by examining our students' content area scores on the…

In this paper, the five interlocking de Bono LAMS sequences are introduced as a new form of generic template designs. This transdisciplinary knowledge-mobilising strategy is based on Edward de Bono's attention-directing ideas and thinking skills, commonly known as the CoRT tools. The development of the de Bono LAMS sequence series is an important…

Due to its complex and microscopic nature, genetics is a difficult subject for many learners to conceptually grasp. Graphics, animation and video material can be extremely helpful to their understanding. A wealth of educational online content about genetics has been created over the past decade in the wake of the human genome being sequenced.…

Describes the general principles of a nonexperimental learning theory-based courseware evaluation which calls attention to instructional sequences in the courseware to determine if the sequence is programed around learning principles. The results of using this type of evaluation for two computerized training devices are summarized. (MBR)

Reviews instructional design research and theory and relates it to the design of computer-based instructional materials. Instructional design guidelines are offered to aid software developers in making design decisions on three macrolevel and four microlevel of instruction. (Author/LRW)

Describes a study that compared three graduate level hypermedia courses and investigated whether a certain sequence or specific content might affect students' attitudes toward hypermedia. Authorware-based courses are compared with HyperCard-based courses, and the use of the Stages of Concern Questionnaire is discussed. (LRW)

Discusses issues involved with buying and using multimedia authoring programs. Six programs are compared: (1) MediaText, (2) HyperCard, (3) LinkWay Live!, (4) AmigaVision, (5) Director, and (6) Multimedia Desktop. Highlights include the use of multimedia in education, sequential versus hierarchical organization, price, system requirements, digital…

Reviews authoring systems and languages for computer-based instruction (CBI) used in postsecondary institutions and identifies developments needed to promote effective authoring of CBI. Topics discussed include features of typical authoring environments, including prototype format, sequence, and menu orientation; software development; and…

With vigorous development of the Internet, e-learning system has become more and more popular. Sharable Content Object Reference Model (SCORM) 2004 provides the Sequencing and Navigation (SN) Specification to define the course sequencing behavior, control the sequencing, selecting and delivering of course, and organize the content into a…

Outlines technological and cognitive considerations in the selection of authoring systems for writing computer-assisted instruction (CAI) lessons. Topics discussed include hardware selection; documentation; text display; screen appearance; branching and sequencing; text editing; graphics; animation; sound and voice input and output; student…

Describes a teaching strategy using Apple IIe computers in a sequence of individual conferences. Includes asking questions while scrolling through the paper, showing students how to elaborate ideas by entering suggested changes and prompts in capital letters during the conference, and using a spelling checker to prompt revision (e.g., by compiling…

Discussion of menu design strategies for computer-assisted instruction (CAI) focuses on a study that investigated whether menu design would affect undergraduate learners' usage patterns during a CAI lesson. Sequential versus random selection of options is discussed, and new measures for describing usage patterns in CAI are explained. (eight…
