In secondary science education, the learning and teaching of coherent conceptual understanding are often problematic. Context-based education has been proposed as a partial solution to this problem. This study aims to gain insight into the development of conceptual coherence and how context-embedded learning-teaching activities (LT) can promote…

Error in science is a prime occasion to teach the nature of science, especially the central feature of tentativeness. Error types also reflect corresponding methodologies of science, critical for practicing science and (in a context of scientific literacy) analyzing its claims. Effective efforts in teaching about error will ideally be informed by…

Conceptual change is often described as a causal process in which changes in an embraced system of beliefs result in a new system of beliefs. Here, it is argued that conceptual change is better understood as an intentional activity with regard to the learner, that is, what the learner is doing when trying to understand something. Children were…

In this article, we adopted the relational conceptual change as our theoretical framework to accommodate current views of conceptual change such as ontological beliefs, epistemological commitment, and social/affective contexts commonly mentioned in the literature. We used a specific concept mapping format and process--digraphs and digraphing--as…

To explore the ways in which teacher-guided and student-centered instructional approaches influence students' conceptual understanding of seasonal change, we designed a technology-enhanced learning (TEL) course to compare, by means of concept maps, the learning outcome of students in two groups: a teacher-guided (TG) class (with whole-class…

Analyzes verbal and figural student concept schemes for environmental issues through aspects of differentiation (number of categories employed), discrimination (range of phenomena involved), and integration (efficiency of organizing method). Results indicate students (N=28) use discrimination most and integration least and constructed…

Explores the effectiveness of concept mapping, the learning cycle, expository instruction, and a combination of concept mapping/learning cycle in promoting conceptual understanding of diffusion and osmosis. Concludes that the concept mapping/learning cycle and concept mapping treatment groups significantly outperformed the expository treatment…

Suggests that the construction and reconstruction of meanings by learners requires that they actively seek to integrate new knowledge with knowledge already in their cognitive structure. Concept mapping has been used effectively to aid meaningful learning with resulting modification of student's knowledge structures. Asserts that new computer…

Forty-six students enrolled in a high school physics course participated in a study designed to portray student views on, and understanding of, collaborative concept mapping. Students demonstrated a good understanding of concept maps and emphasized their usefulness as a learning tool. (56 references) (ZWH)

Contemporary assessment practices in science education have undergone significant changes in recent decades. The basis for these changes and the resulting new assessment practices are the subject of this two-part paper. Part 1 considers the basis of assessment that, more than 25 years ago, was driven by the assumptions of decomposability and…

Reports on part of a larger study of how 11- and 12-year-old students construct knowledge of electricity and magnetism by drawing on aspects of their experiences during the course of a school visit to an interactive science museum and subsequent classroom activities linked to the science museum exhibits. (Contains 24 references.) (Author/YDS)

Investigates high-achieving fifth-grade students' achievement gains and conceptual reorganization on convection. Features an instructional sequence of three dyadic inquiry investigations related to convection currents as well as pre- and post-assessment consisting of a multiple-choice test, a card sorting task, construction of a concept map, and…

Reports results of metanalysis of 19 studies on concept mapping (CM) in science instruction. Results showed CM has positive effects on student achievement and attitudes. Differences in achievement depended on science content class, with biology being most favored. Smaller differences in achievement were found when CM groups were compared to a…

Describes the practice of concept mapping, the student-student and student-teacher interactions, and cognitive activity occurring in participants. Authors conclude that concept mapping is an excellent activity that allows students to engage in extended science discourse. The maps provide students with a means to learn the language patterns of…

The relationship between concept mapping and comprehension was investigated in conjunction with science instructional laboratories. Measured were student skills and aptitudes applying aptitude treatment interaction procedures to investigate interactions between a concept mapping treatment and student aptitudes. (KR)
