In this paper we suggest using general system theory (GST) as a unifying theoretical framework for science and technology education for all. Five reasons are articulated: the multidisciplinary nature of systems theory, the ability to engage complexity, the capacity to describe system dynamics and change, the ability to represent the relationship between the micro-level and macro-level of analysis, and the ability to bring together the natural and human worlds. The historical origins of...

Two areas of learning research, research about the learning process and views about the learner, need to be considered to guide educational stakeholders in the task of successfully redesigning schools to promote learning. The most meaningful learning results from an instructional design based on learning research. Research in the application of systems theory in education has profound implications for curriculum, instruction, and assessment in schools.

Much social and behavioral research involves hierarchical data structures. . . . Recent developments in the statistical theory of hierarchical linear models now afford an integrated set of methods for such applications. This introductory text explicates the theory and use of hierarchical linear models (HLM) through rich, illustrative examples and lucid explanations. The presentation remains reasonably nontechnical by focusing on three general research purposes—improved estimation of effects...

Our concern in this paper is with the validity of educational tests when they are employed as critical measures of educational outcomes within a dynamic system. The problem of validity arises if an educational system adapts itself to the characteristics of the outcome measures. We introduce the concept of systemically valid tests as ones that induce curricular and instructional changes in education systems (and learning strategy changes in students) that foster the development of the...

Valid measurement scales for predicting user acceptance of computers are in short supply. Most subjective measures used in practice are unvalidated, and their relationship to system usage is unknown. The present research develops and validates new scales for two specific variables, perceived usefulness and perceived ease of use, which are hypothesized to be fundamental determinants of user acceptance. Definitions for these two variables were used to develop scale items that were pretested...

Raging during the 1980s, the Paradigm Wars resulted in the demise of objectivity-seeking quantitative research on teaching—a victim of putatively devastating attacks from anti-naturalists, interpretivists, and critical theorists. Subsequently, the interpretivists' ethnographic studies flourished, enhancing the cultural appropriateness of schooling, and critical theorists' analyses fostered the struggles for power for the poor, non-Whites, and women. Two alternative versions of the aftermath...
