Argues that a skills-based approach for the assessment of laboratory work is philosophically unsound, educationally worthless, and pedagogically dangerous. Proposes an alternative, holistic approach to assessment, based on a more valid model of scientific practice. (Contains 38 references.) (MDH)

This article describes a model of collaborative study and field placement with undergraduate students in elementary education and special education at the State University of New York in Plattsburgh. It provides a rationale for collaborative teacher education and a proposed course structure to fit into existing teacher education programs as an…

Modeling is important in science and in science education. Computer-based modeling opens up new possibilities for learning science, particularly now that appropriate software is available. This article describes high school students' use of Model Builder software in high school classrooms. (PR)

Discusses the use of augmentative and alternative communication (AAC) to enhance comprehension and expression of people with autism. A theoretical model for AAC assessment and intervention is presented and illustrated with a case study of a 6-year-old boy with autism and severe expressive and receptive language impairments. (Author/DB)

Reviews strategies for helping prepare preservice and inservice English-language and content-area teachers to help students to function in English-as-a-Second/Foreign-Language classrooms in elementary, secondary, and tertiary educational contexts around the world. Strategies are drawn from three models of teacher development: craft or training,…

This article describes the evolution of distance learning in English-as-a-Second-Language (ESL) instruction from the 1970s to the present, focusing on the "guided didactic conversation" model of Holmberg (1983, 1986), examples of distance learning ESL programs, and a new model of distance learning based on computers and electronic communication.…

Presents one approach to handling the trade-off between reducing uncertainty in environmental assessment and management and additional expenses. Uses the approach in the evaluation of three alternatives for a real time river water quality forecasting system. Analysis of risk attitudes, costs and uncertainty indicated the levels of socioeconomic…

Examines the representation of the reading process in English as a Foreign Language (EFL) texts. The article argues that many of these representations are dated and based on a theory that was never a mainstream theory of first-language reading. Suggestions for exercises to strengthen automatic word recognition in EFL readers are provided. (33…

Presents definitions of literacy followed by an overview of selected views of literacy development, and suggests how these constructs inform the teaching of reading. A recent model of reading development is described, along with suggestions for using the model, particularly for learners at risk. The article concludes with a discussion of…

Describes a new analytical tool, data envelope analysis (DEA) model, which can provide better understanding of the efficiency of academic research libraries. Reports the results of a study using 1994-1995 Association of Research Libraries statistics together with expert judgments, in terms of constraints, to make the model more applicable to the…

Discusses the value of role-play in developing interpersonal skills and presents a 10-step model to help performance technologists design effective role-plays. Highlights include training objectives; designing assessment instruments; task analysis; generality and demonstration; designing social-communicative problems for the content; practice; and…

Argues that current computer-based instruction does not exploit the instructional possibilities of computers. Critiques current models of computer-based instruction: behaviorist as too linear and constructivist as too unstructured. Offers a design model of Expanded-frame Hypermedia Knowledge-bases as an instructional approach allowing hypermedia…

Earth science teachers know how frustrating it can be to spend hundreds of dollars on three-dimensional (3-D) models of Earth's geologic features, to use the models for only a few class periods. To avoid emptying an already limited science budget, the author states that teachers can use a simple alternative to the expensive 3-D models--sand. She…

We annotated transcripts of human tutoring dialogue for the purpose of constructing a dialogue-based intelligent tutoring system, CIRCSIM-Tutor. The tutors were professors of physiology who were also expert tutors. The students were 1st year medical students who communicated with the tutors using typed communication from separate rooms. The tutors…

For three biology professors, visualizing molecular processes is central to thinking in their discipline. This chapter reports their attempts at getting students to make this same cognitive move and the results of their assessments. (Contains 2 figures.)
