Part two of a proposal for a unified, sequential approach to environmental education. Presents a working model for the environmental education curriculum and expert reactions to the model. (LZ)

Storyboarding, the process of sketching visual and narrative information to plan media productions, can be an effective tool for designing instructional materials. Storyboarding enables organization and sequencing, expansion and reduction of content, text development, selection of production medium, and formulation of sensitive evaluation…

Describes design logic and potential uses of a variant of the multiple-baseline design. The multiple-baseline multiple-sequence (MBL-MS) consists of multiple-baseline designs that are interlaced with one another and include all possible sequences of treatments. The MBL-MS design appears to be primarily useful for comparison of treatments taking…

My purpose in this paper is to present a didactic tool--a set of specially designed problems and questions for discussion--that can help making students better aware of the various aspects of the formal notion of limit of a sequence. The didactic tool will be justified using results from my own and other authors' research on students' naive or…

The design of a web-based hypermedia learning solution requires a robust design process--a full iteration that conceptually, metaphorically, structurally and navigationally defines a solution with the end users at its core as exemplified by Kommers (2001). Initially this process was considered as a sequential, hierarchical pyramid from conceptual…

This paper is based on a study of how students' read nature in different ecosystems. Its focus is on ecology and the context is outdoors. This literacy has to do with an ability to recognise organisms and relate them to material cycling and energy flow in the specific habitat that is to be read. A teaching sequence was designed in order to develop…

The authors propose new procedures for evaluating direct, indirect, and total effects in multilevel models when all relevant variables are measured at Level 1 and all effects are random. Formulas are provided for the mean and variance of the indirect and total effects and for the sampling variances of the average indirect and total effects.…

Almost every K-8 technology activity includes feedback. Technology teachers generally view the input-process-output paradigm as being incomplete. A step toward completion would be the inclusion of a "feedback" component incorporating reengineering. This article provides an example of how one activity evolved through several stages to include…

Using two sequential key press sequences, we tested the extent to which subjects' performance on a digital piano keyboard changed between the end of training and retest on subsequent days. We found consistent, significant improvements attributable to sleep-based consolidation effects, indicating that learning continued after the cessation of…

Research tells us that specialized training and education of teachers is one of the strongest predictors of child care quality. In the late 1960s, however, most states did not require preservice training or higher education for teachers in early childhood programs or family child care homes. At that time, Missouri wanted to develop a project that…

This article reports on a research effort that investigated whether the use of Microcomputer-Based Labs (MBLs), implemented within an inquiry-based activity sequence on phase transformations (melting and freezing), contributes to the development of fourth grade (9-10 year-old) students' conceptual understanding and ability to construct and…

This article provides unbiased estimates of the proportion of items in an item domain that an examinee would answer correctly if every item were attempted, when a closed sequential testing procedure is used. (Author)

Classifies various syntactic structures normally included in sentence-combining instruction into five categories: coordinates, adverbials, restrictive noun modifiers, noun substitutes, and free modifiers. Within each category, structures are further divided into three levels to provide teachers with guidelines for planning instruction. (RH)

It is suggested that the methodology for developing communicative competence in a second language is not always in keeping with the principles behind it. Two directions are suggested: use of grammatical sequencing for those students it suits best, and gradual introduction of complexity into the communicative situation. (MSE)

Analyzed case study presented by Hill, Carter, and O'Farrell (1983) with sequential analysis methods developed to demonstrate the usefulness of these methods for understanding counseling process and outcome. Sequential analysis method revealed several facets of interaction between counselor and client that were undetected by Hill et al.'s…
