This study examined the reflection interview as a tool for assessing and facilitating the use of "systems language" amongst 11th grade students who have recently completed their first year of high school biology. Eighty-three students composed two concept maps in the 10th grade--one at the beginning of the school year and one at its end.…

Children and adolescents spend a large part of their day at school. Physical and mental problems result from physical inactivity, sitting positions at work and "indoor lifestyle" (WHO 2004). Therefore, health education is a major topic in school. Biology classes (scholastic) can make an important contribution in this context. Health as a…

Visualizing the chemical structure and dynamics of particles has been challenging for many students; therefore, various visualizations and tools have been used in chemistry education. For science educators, it has been important to understand how students visualize and represent particular phenomena--i.e., their mental models-- to design more…

The "flipped classroom" is an educational strategy about inverting the traditional use of in-class time for conducting lower-level learning activities and out-of-class time for conducting higher-level learning activities. "Guided social inquiry learning" (GSIL), which is a scaffolded constructivist pedagogic approach, has been…

Movement skill competence is important to organised youth physical activity participation, but it is unclear how adolescents view this relationship. The primary aim of this study was to explore adolescents' perception of the relationship between movement skills, physical activity and sport, and whether their perceptions differed according to…

The purpose of this study was to determine the relationship between the basic concepts related to the unit of "Chemical Reactions and Energy" and the sub-concepts underlying for meaningful learning of the unit and to investigate the effectiveness of them on students' learning achievements. For this purpose, the basic concepts of the unit…

The study aimed to determine the comparative effectiveness of context-based and traditional teaching approaches in enhancing student achievement in genetics, problem-solving, science inquiry and decision-making skills, and attitude towards the study of life sciences. A mixed method but essentially quantitative research approach involving a…

Background and purpose: Active-learning as a student-centered learning process has begun to take more interest in constructing scientific knowledge. For this reason, this study aimed to investigate the effectiveness of active-learning implementation on high-school students' understanding of "acids and bases". Sample: The sample of this…

This study was conducted to explore the effectiveness of conceptual change oriented instruction over traditional instruction on students' understanding of acids and bases concept. Besides, effects of gender difference and science process skills on students' understanding of acids and bases were also investigated. Analysis of the results showed…

In this study, whether or not constructivist teaching of double-slit interference of light has a positive effect on the secondary school students' conceptual change is examined. An achievement test, a conceptual understanding test and semi-structured interviews were used as data collection tools in this mixed methods research. Experimental group…

In l976 Dane County, Wisconsin was the site of a survey to determine the knowledge of rural youth and adults as to how their government functioned. The area was chosen because its residents were thought to be more politically active than individuals in other parts of the state. Personal or telephone interviews were conducted with 112 adults and…

The present paper presents a detailed thematic review of chemical bonding studies. To achieve this, a matrix is developed to summarize and present the findings by focusing on insights derived from the related studies. The matrix incorporates the following themes: needs, aims, methods of exploring students' conceptions, general knowledge claims,…

This paper describes an English language listening test intended as computer-based testing material for secondary school students in Hong Kong, where considerable attention is being invested in online and computer-based testing. As well as providing a school-based testing facility, the study aims to contribute to the knowledge base regarding the…

Our main goal in this study was to explore whether the use of models in molecular genetics instruction in high school can contribute to students' understanding of concepts and processes in genetics. Three comparable groups of 11th and 12th graders participated: The control group (116 students) was taught in the traditional lecture format, while…

A comparison was made of student understandings of marine science and marine resource concepts in two geographically distant but similar sociocultural regions of the United States. The study is based on the nature of ecological events, students' understanding in the context of meaningful learning, and the cultural context in which learning takes…
