The abstractness of the chemistry concept can be understood easily through chemistry learning using multiple representations. This article used the Systematic Literature Review (SLR) method to review eleven articles published from 2012 to 2021 and focused on chemistry learning using various representations. The articles are systematically obtained…

In this study a distinction is made between routine, semiroutine, and nonroutine problems based on the problem solver's knowledge. Routine problems are solved by applying a known procedure, semiroutine problems require planning that uses functional knowledge, and nonroutine problems require generation of new functional knowledge. Nonroutine…

Back-of-the-envelope problems call for approximate calculations of quantities that can be related to information in a person's knowledge but are not solved precisely. These problems provide an opportunity for the study of processes and the role of general knowledge in ill-defined problem solving. Subjects with advanced and intermediate knowledge…

This project addressed the question: What knowledge and processes enable individuals to construct and modify representations of novel, nonroutine problems? The theoretical goal was to extend the information-processing theory of problem solving to include processes that have been characterized as restructuring of problems and productive thinking by…

Evidence from video tapes of experts thinking aloud and using analogies in scientific problem solving is presented. Four processes appear to be important in using an analogy: (1) generating the analogy; (2) establishing confidence in the validity of the analogy relation; (3) understanding the analogous case; and (4) applying findings to the…

Science education has often struggled to determine effective teaching methodologies and learning strategies. One promising field of research has been that of alternative frameworks. The research described in this paper describes how immersion in an unfamiliar environment and culture affected teacher learning, some of the significant experiences…

Presented are four research articles and staff development activities. Included are: an activity used to stimulate discussion of the issue of balanced science; a constructivist approach to teaching electric circuits; a science grading scheme; and a discussion of priorities in science education. (CW)

The nature of cluster analysis and dendograms, subjects, tasks, and results of this study are described. Categories for problems were based on assumptions about the methods used by novice and expert problem solvers in a physics context. (CW)

Reports a study which identified different problem-solving strategies among Hong Kong high school chemistry students. Finds that student experts employed a recognition plus a working forwards strategy, whereas student novices attempted a means-end analysis to create a solution procedure. Comparisons were made with problem-solving in physics. (GG)

Described are the comprehension monitoring abilities of science students when reading science textbooks. The incorrect use of schemata and the limiting influence of metacognitive abilities on the improvement of meaningful learning is discussed. (KR)

Discussed is the relationship of concept-mapping by students to the meaningful learning of genetics and ecological concepts. The implications of these results for teacher education in biology are addressed. (KR)

Examines quantitative models in school physics, looking particularly at the degree to which they match the real world. Explores the positive aspects of a mismatch between models and real world conditions. (DDR)

Explores whether construction of integrated knowledge structures by students can be stimulated by concept mapping and better visualization of concepts and their interrelationships. Significant effects of concept mapping as an instructional method could not be detected. (Contains 18 references.) (DDR)

Informs teachers about using concept maps as a learning tool and alternative assessment tools in education. Presents research results of how students might use concept maps to communicate their cognitive structure. (Author/KHR)

This paper posits a cognitive model for understanding and learning physics that is an alternative to the formal deductive system. Recent findings of Fuller, Karplus, Lawson, and others are cited in arguing against using a formal deductive approach to teaching physics. The model demonstrates types of action-oriented knowledge structures as they…
