Provides information on a 5-year study that tracks children's ideas and attitudes toward science. Follows children's ideas using the topic of photosynthesis. (YDS)

Nine sixth-grade students were asked to identify plants by their common names. In the event that students did not know the correct response, researchers observed a variety of avoidance strategies. The study demonstrated that students at the elementary level should be introduced to the concept of genus before more abstract levels of the botanical…

Presents an interview protocol used to identify and evaluate students' conceptions of plants which is an invitation to participate in the third national study exploring elementary students' science conceptions. (YDS)

Previous research of classroom teaching and learning revealed that students have critical misconceptions about how plants get their food and that these misconceptions remain unchanged despite instruction using activities in the Science Curriculum Improvement Study (SCIIS) unit on producers. Because the experimental sequence described in SCIIS is…

This study is intended to develop an assessment instrument to investigate students' understandings about internal transport in plants and human circulatory system. A refined process of a two-tier diagnostic test was used to develop the instrument. Finally, three versions of the Internal Transport in Plants and the Human Circulatory System test…

Presents a study in which the conversations of primary school groups were collected in a botanical garden and analyzed for content. The data were examined for the effects of the presence or absence of an adult in the group, age, and the sex of the pupils. (Contains 27 references.) (Author/DDR)

The relationship between language, thought, and concept formation has been a central issue in many studies and theoretical discussions in various domains--philosophy, psychology, anthropology, and linguistics. The relation between language and concept development can be framed as two opposing questions: (1) Does the child learn concepts first and…

The Learning in Science Project (Primary)--LISP(P)--investigated the ideas and interests children have about flowering plants (in particular whether these plants have a life cycle). Data were obtained from: individual interviews with children, ages 7- to 14-year-old (10 students for each age level), using the "interview-about-instances"…

Illustrates the concept of phototropism and the development of root systems using a classroom-constructed clinostat. Provides instructions to construct the clinostat and tips to promote plant growth. (MDH)

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…
