Formal climate education without consideration of the ocean is incomplete. The effectiveness of a new climate lesson for youth that includes the ocean-climate nexus was examined by delivering the lesson to nine classes situated in separate British Columbia, Canada public schools and assessing the students' understanding of basic climate concepts…

International examination results have already influenced many countries to make radical reforms in education system. According to these results countries have been categorized as high, middle and low achievement in education. Turkey has also taken these results into consideration quite seriously and started to investigate to what extent there are…

According to Klahr's (2000, 2005; Klahr & Dunbar, 1988) Scientific Discovery as Dual Search model, inquiry processes require three cognitive components: hypothesis generation, experimentation, and evidence evaluation. The aim of the present study was to investigate (a) when the ability to evaluate perfect covariation, imperfect covariation,…

Identifies and describes the problems students have with the concept of neutralization. Analysis of over 7,500 students' answers to test questions over neutralization showed that many students understand the concept in its original meaning. Students assumed that in any neutralization reaction a neutral solution is formed, even if a weak acid or…

Many science educators are concerned with students' ability to understand science as a process and with their conceptions of scientific knowledge. Preliminary work has shown that the use of a model organizer can result in student perceptions of improved understanding, but the reason for this effect is not known. This research was undertaken to…

It can be inferred from the corpus of misconception research that an assumption that students come into secondary and college classes with a relatively homogeneous view of the world has been made. This paper takes the position that this assumption keeps researchers from a more comprehensive understanding of the factors that lead to science…

Described is the development and validation of a test designed to assess the cognitive levels of Jamaican sixth graders. Instead of the usual clinical procedure, a 30-minute videotaped test was designed in order to standardize variables associated with the test's administration. The film presented situations involving seven conservation concepts…

Reports the design of the "Mechanics Baseline Test," an instrument to assess students' understandings about concepts in mechanics. Discusses how comparisons of test results with extensive baseline data can be used to evaluate instruction at all levels. Includes a copy of the instrument. (MDH)

Reports on misconceptions held by intermediate grade students concerning chemistry textbook concepts, on the relation of reasoning ability to those misconceptions, and on the extent that textbooks encourage misconceptions. Concludes that the level of understanding displayed for the selected concepts, in combination with the nature of students'…

Conceptual change teaching is an instructional method that helps students modify, extend, or exchange their alternative conceptions for the appropriate scientific conceptions. Provides activities and a diagnostic test to apply the method to the concepts of heat and temperature. (MDH)

Critical pedagogy, an ideology which opposes education as domination, views knowledge and learning as constructed by the student and teacher together. Its goal is personal and social emancipation and empowerment. The purposes of this paper are to (1) indicate problems in science education which can be addressed by teaching science from a critical,…

Describes an analysis of test items used to measure the science process skills of 11-year-olds in Great Britain. Concludes that the level of cognitive demand was a reliable predictor of the difficulty of an item. (TW)

The purpose of this project was to find and make clarifications about the uniqueness and similarities on various aspects of science education programs in Japan, the Republic of Korea, the United States, and the Philippines that could provide the basic considerations on curriculum development. Included are: (1) an introduction to the research; (2)…

The purpose of this study was to investigate the relationship between the achievement of some abstract concepts in "molecular genetics" and prior knowledge, formal reasoning ability, and sex. The major findings of the study were: (1) prior knowledge had a high significant correlation with the achievement of abstract concepts; (2) the…

The concept of the density of a material has an important role in elementary and secondary school science curricula, but it is a difficult concept to grasp. This project explores why this should be and whether there are some simpler, more accessible notions which can serve as the basis for building a concept of density in students' minds during…
