Theoretical and empirical research on argument and argumentation in science education has intensified over the last two decades. The term argument in this review refers to the artifacts that a student or a group of students create when asked to articulate and justify claims or explanations whereas the term argumentation refers to the process of…

Explores two differing perspectives of the nature of students' biological knowledge structures, conceptual frameworks, and phenomenological primitives (p-prims). Indicates that although a more prevalent description of student conceptions could not be discounted, p-prim of need as rationale for change was found to offer useful description of…

Discusses the relationships between physical, mathematical, and mental models in the process of constructing and understanding physical theories. Attempts to interpret research findings with college students regarding mental models and physics education under the framework of Johnson-Laird's mental model theory. (Author/MM)

Visual representations are essential for communicating ideas in the science classroom; however, the design of such representations is not always beneficial for learners. This paper presents instructional design considerations providing empirical evidence and integrating theoretical concepts related to cognitive load. Learners have a limited…

Employs latent partition analysis (a multivariate technique) to reveal pre/postcognitive structure of freshman engineering students (N=70) taking general chemistry. Similarities and dissimilarities among high and low scorers are discussed. Arguments for use of this statistical techniques are presented. (DH)

Examines the position of students' understanding of natural phenomena as being theoretical. Reviews philosophical and cognitive arguments presented by G. Hills in support of such a position. Advances alternate viewpoints. (Author/MKR)

Assesses ideational networks based on a written narrative of seventh grade students who had begun a unit on evolution. Indicates that students who scored high on the content analyses of their written narrative and whose narrative contained extensive ideational network linkages also tended to use a logical, sequential rule of ordering their…

Using conceptual change as theoretical lens, describes the structure of (n=4) learners' conceptual ecology within biological evolution and illustrates how this ecology influences the process of conceptual change. Prior conceptions relate to evolutionary theory, scientific and religious orientations, view of biological world, and acceptance of…

Explores how some of the work in the history and philosophy of science might develop a more adequate understanding of students' untutored ideas. Describes how students' views can be interpreted. Explains and discusses the merits of commonsense-scientific theory analogy. (YP)

Examined the feasibility of using two microcomputer simulations to improve preservice elementary teachers performance in the formation and testing of hypotheses. Considers the effects of mode of computer instruction and cooperation on the acquisition of skills. (CW)

School science students can benefit greatly from participation in student-directed, open-ended scientific inquiry projects. For various possible reasons, however, students tend not to be engaged in such inquiries. Among factors that may limit their opportunities to engage in open-ended inquiries of their design are teachers' conceptions about…

Investigated the role of "a priori" ideas in planning experiments and data processing leading to inferences. Thirty-one students (ages 11-13) observed a "combustion/candle in a closed container" experiment and were asked to interpret sets of measurements. Findings, among others, show that children preferentially experiment on…

Propositions expressed by students during interviews prior to and after audiovisual instruction served as the basis for Concept Propositional Analysis (CPA) to assess cognitive structure. CPAs for two students are reported and aspects of Ausubelian principles are discussed. The method showed that new learning can be linked to previous…

Describes a study that investigated whether scientific and nonscientific understandings in the same content area are linked. Finds that students' (n=107) explanations indicate that they were using an "if-then" type of reasoning which linked scientific and nonscientific conceptions. Contains 39 references. (Author/WRM)

Investigates several aspects of undergraduate students' rules for projectile motion including general patterns; rules for questions about time, distance, solids and liquids; and changes in rules when asked to ignore air resistance. Reports approach differences by sex and high school physics experience, and that novice rules are situation…
