Development of cognitive skills is critical for developing the right conceptual ideas in chemistry. Atomic structure, bonding, and associated properties are taught as parts of high school chemistry courses worldwide. The cumulative build-up of misconceptions about the periodic table is to blame for students' poor performance on atoms and…

Scientific literature about neuromyths has proliferated in the last few years. However, there is a gap of knowledge around neuroedumyths. While neuromyths are based on hoaxes about the brain, neuroedumyths use neuroscientific concepts but state consequences for education that are false. This article presents, for the first time, research about…

Although taxonomic proficiency is a prerequisite for understanding ideas central to biology, previous research has established that learners frequently misclassify animals by not following the tenets of accepted taxonomic rubrics. This has immediate relevance with the recently revised English National Curriculum now requiring concepts of animal…

Previous research indicates children reason in different ways about horizontal motion and motion in fall. At the same time, their understanding of motion down inclines appears to result from an interaction between horizontal and vertical motion understanding. However, this interaction is still poorly understood. Understanding of speed change may…

Do we perceive correctly whether a 2-D object is balanced or unbalanced? What would be the cause of biased equilibrium judgments? In two psychometric studies, we varied independently the characteristics of the objects and the equilibrium states. First, we observed that observers were excessively sensitive to the eccentricity of the object top.…

We present a programme for a novel introductory lower-secondary chemistry course (seventh or eighth grade) that aims at the application of theories of science education, and in particular of conceptual/meaningful learning and of teaching methodology that encourages active and inquiry forms of learning The approach is rigorous with careful use of…

Based on the analysis of available research on students' alternative conceptions about the particulate nature of matter, we identified basic implicit assumptions that seem to constrain students' ideas and reasoning on this topic at various learning stages. Although many of these assumptions are interrelated, some of them seem to change or…

The purpose of this study was to investigate the effects of a Computer-Assisted Instruction designed according to 7E model of constructivist learning(CAI7E) related to "electrostatic'' topic on physics student teachers' cognitive development, misconceptions, self-efficacy perceptions and attitudes. The study was conducted in 2006-2007…

This ERIC Digest concerns the constructed knowledge (also called nave knowledge or prior conceptions) held by students and the changes required to alter students' framework to understand and believe the true science concepts involved. This process is called conceptual change. Theoretical framework of conceptual change, what exactly is conceptual…

Analyzes students' attempts to answer examination questions involving stoichiometry and chemical equilibrium and reports that the majority of the students do not fully understand either concept. Concludes that the main difficulty with these topics is that they are highly abstract and first taught to students before they have reached the stage of…

Two questionnaires were given to 38 students (16-18 year olds), in which they were asked to classify a list of different conceptual entities by several ontological features. The results suggest the form of a fundamental "ontological space" and locate some scientific concepts in this space. (Author)

Provides teachers with some ideas about the development of physical knowledge to make them more receptive to the differences between their own and their students' thinking. Illustrates an adapted version of Piaget's model of the growth of physical knowledge using the development of classical mechanics. Contains 12 references. (Author/JRH)

Combined free response questionnaire and interview procedure are used to probe students' ideas regarding how they believe they see both luminous and nonluminous objects and how they think they hear source of sound. From large sample of students studied (n=1901), prevalence of ideas in different age groups is compared, and progression can be seen.…

In an effort to investigate the effects of a teaching strategy that helps students to identify concept conflicts through experimentation and guided investigation on students' conceptual changes and learning outcomes, 596 students (393 junior high school, 170 senior high school, and 33 college students) were administered two solution tests…

The processes of photosynthesis and respiration are basic to the understanding of many other aspects and functions of biological systems. Because of their curricular significance, these processes served as the focal point in an investigation of student conceptions and instructional effectiveness. In this study, students in a college nonscience…
