The research compares teachers' and their pupils' performance on plant nutrition. The misconceptions of 89 primary school children from one state school have been compared with those of their four teachers. A questionnaire and a drawing task were used for data collection. The results evidence that children and teachers have serious shortcomings…

The Arnold Arboretum Field Study Program provides outdoor experiences for children in order to develop authentic firsthand knowledge of life sciences. The Arboretum welcomes approximately 3,200 children (preK-5) from greater Boston annually. During the program called Explorations with Head Start participants, the children visit three times…

"Green" has a common use among the public. Both natural and social environment have an important effect on this expression. People tend to explain the scientific concepts using well-known situations which they intensively see around the living area. In this sense, photosynthesis is one of the most important biological concepts including…

Not only is science perceived by some as a hard-to-teach subject, but there are certain topics that all teachers regard as notoriously hard to teach. While their natural inclination may be to eliminate some of the details, teachers have to be careful not to water down the curriculum. How do they share the complexity of the natural world without…

Effective instruction requires continual assessment of student understanding to identify and redirect misconceptions. This is particularly important when dealing with topics that seem straightforward to the teacher but may go beyond the personal experience of many students, such as the life cycle of flowering plants. Life cycles are a core topic…

Children's trade books about science may be playing an increasing role in science instruction; however, the potential effects on student learning are unknown. To investigate whether a subset of books would be appropriate for classroom instruction about a specific science topic (plant reproduction), a selection of children's books about plants was…

The purpose of this study was to investigate how concept cartoons, together with other diagnostic and scaffolding tools, could be used in formative assessment, to stimulate talk and argumentation among students in small groups, as part of peer-assessment and self-assessment; and to provide diagnostic feedback about students' misconceptions to the…

In this article, the author presents and discusses activities that use a phenomena-first, guided inquiry approach to teach important concepts related to plant function, as well as the history and nature of scientific inquiry. These activities are intended for use with students in grades 3-8, as well as in elementary science methods courses. The…

In this study, the attitudes of Israeli children aged 6 to 15 years were surveyed regarding their conceptions of plants as living things. It was desired to find out whether children consider plants to be alive, the knowledge differences between the different age groups in the study, how children classify plants according to biological criteria and…

Because the National Science Education Standards (1996) outline specific things K-8 students should know about plants, and previous data indicated that elementary students had difficulty understanding some major ideas about plants and plant growth, the authors of this article thought it appropriate to initiate an investigation to determine the…

An ethnographic study was conducted with the goal of comparing the botanical knowledge of nine sixth grade students with the botanical concepts developed in the elementary textbook series, Science, by Silver Burdett, 1985. The extent to which the child's conceptual framework resembles that of the scientist and the extent to which the textbook…

Many researchers believe that prior knowledge is the single most important variable influencing learning. Learning in the classroom is determined or affected positively or negatively, to some degree, by the knowledge people bring to the classroom. This study was designed to: (1) assess fifth- and eighth-grade Korean students' misconceptions of…

The superordinate problem that the Threshold Project addressed is the nature of the language and learning difficulties that South African Standard 3 (Std 3) children experience when they change from their mother tongue to English as a medium for instruction. The primary focus of the Threshold Project work in 1987 was on a section of the South…
