Genetic engineering is now an integral part of many high school textbooks but little work has been done to assess whether it is being properly addressed. A checklist with 19 items was used to analyze how genetic engineering is presented in biology textbooks commonly used in Spanish high schools, including the content, its relationship with…

Epidemic levels of obesity represent a growing public health problem associated with a variety of negative health outcomes. Population level interventions that aim to moderate obesigenic environments have been proposed but remain largely unimplemented. Standard individual level interventions that focus on dietary restraint have been ineffective…

The use of inquiry-based laboratory in college science classes is on the rise. This study investigated how five nonmajor biology students learned from an inquiry-based laboratory experience. Using interpretive data analysis, the five students' conceptual ecologies, learning beliefs, and science epistemologies were explored. Findings indicated that…

Research work in science education is a special area of scholarship within the scientific enterprise. The scientific enterprise ranks with the arts and religion as one of the major areas of human endeavor. Science education can be classified within science, albeit it stands as a poor cousin when compared with physics, biology and other fields. The…

In this study, we examined how students' levels of spatial visualization ability interact with learning physics in a microcomputer-based laboratory (MBL) environment. Undergraduate students who had taken an introductory physics course based on MBL tools were pre- and posttested at the beginning and at the end of the semester on spatial…

The objective of this research is to investigate the effects of simulations based on conceptual change conditions (CCS) and traditional confirmatory simulations (TCS) on pre-service elementary school teachers' understanding of direct current electric circuits. The data was collected from a sample consisting of 89 students; 48 students in the…

This study aimed at finding out the effects of Mastery Learning Approach (MLA) on students' achievement in Physics. The study was Quasi-experimental and Solomon Four Non-equivalent Control Group Design was used. The target population comprised of secondary school students in Kieni East Division of Nyeri District. The accessible population was Form…

The goal of this study was to investigate whether integrating a website into chemistry teaching influences 10th-grade students' perceptions of the classroom learning environment, their attitudes regarding the relevance of chemistry, and their understanding of the concept of chemical bonding. Two groups participated in this study: an experimental…

This study explored and documented Taiwanese students' alternative conceptions of animal classification. We examined the understanding of the "animal", "vertebrate" and "invertebrate", "fish", "amphibian", "reptile", "bird", and "mammal" concepts among elementary,…

The purpose of this study was to investigate value of combining Real Experimentation (RE) with Virtual Experimentation (VE) with respect to changes in students' conceptual understanding of electric circuits. To achieve this, a pre-post comparison study design was used that involved 88 undergraduate students. The participants were randomly assigned…

This book highlights women's achievements in science and mathematics from the first century A.D. to the present. Included are paleontologists, geologists, astronomers, mathematicians, chemists, botanists, biologists, engineers, physicians entomologists, and atomic physicists. Their noteworthy accomplishments are translated to students through…

This book contains science activities that are designed to make learning and demonstrating nonpoint source pollution concepts exciting and fun. These activities can either be used alone or with an existing water resources education curricula. Activities include: Water Tasting, Acting Out the Hydrologic Cycle, Concentration of Chemical Pollutants…

The ability to utilize and change energy is one of the most fundamental characteristics of living things. Plants have the unique ability to change light energy into the chemical energy on which human beings depend for such things as fuel and food. Through the activities in this book students examine how plants and other living things use and…

This study was designed to investigate the effects of a dynamic instructional environment, English proficiency, and visualization level, independently and interactively, on middle school students' construction of the concepts of reflection and rotation. The effects of a dynamic instructional environment and English proficiency on students' two-…

The process of students' conceptual change was evaluated during a computer-supported physics unit in a Grade 10 science class. Computer simulation programs were developed to confront students' alternative conceptions in mechanics. A conceptual test was administered as pre-, post-, and delayed post-tests to determine students' conceptual change.…
