The Instructional Practices Log in Science (IPL-S) is a daily teacher log developed for K-5 teachers to self-report their science instruction. The items on the IPL-S are grouped into scales measuring five dimensions of science instruction: "Low-level Sense-making," "High-level Sense-making," "Communication,"…

This study explored third-grade elementary students' conceptions of nature of science (NOS) over the course of an entire school year as they participated in explicit-reflective science instruction. The "Views of" NOS-D (VNOS-D) was administered pre instruction, during mid-school year, and at the end of the school year to track…

There is on-going international interest in the relationships between assessment instruments, students' understanding of science concepts and context-based curriculum approaches. This study extends earlier research showing that students can develop connections between contexts and concepts--called "fluid transitions"--when studying…

This paper examines the use and role of the term "hypothesis" in science teacher education as described by teacher students. Data were collected through focus group interviews conducted at seven occasions with 32 students from six well-known Swedish universities. The theoretical framework is a sociocultural and pragmatist perspective on…

The present study was designed to identify and characterize the major factors that influence entering science teacher candidates' preferences for different types of instructional activities, and to analyze what these factors suggest about teacher candidates' orientations towards science teaching. The study involved prospective teachers enrolled in…

The aim of this research was to develop a model of factors affecting students' ability to interpret external representations (ERs) in biochemistry. The study was qualitative in design and was guided by the modelling framework of Justi and Gilbert. Application of the process outlined by the framework, and consultation with relevant literature, led…

The results presented here derive from a longitudinal study of Swedish upper secondary science students' (16-19 years of age) developing understanding of key chemical concepts. The informants were 18 students from two different schools. The aim of the present study was to investigate the mental models of matter at the particulate level that…

The purpose of the study was to describe the development and application of an instrument to identify various dimensions of the learning environment, as perceived by elementary and middle school students in Taiwan. The instrument, the New Constructivist Learning Environment Scales, includes four dimensions: attitude concerning instruction,…

The study explored the origins of students' data handling knowledge and skills employed during secondary Science lessons. Transfer of learning was explored in an authentic school context, describing when transfer does and does not occur, conditions that appear to foster transfer, and impacts of different types of transfer on teaching and learning.…

This paper is based on a study of how students' read nature in different ecosystems. Its focus is on ecology and the context is outdoors. This literacy has to do with an ability to recognise organisms and relate them to material cycling and energy flow in the specific habitat that is to be read. A teaching sequence was designed in order to develop…

Reanalyzes pretest and posttest interviews from a large classroom study using a situated cognition framework. Concludes that cognition is a dynamic process that changes in different ways over shorter and longer time scales. Contains 40 references. (DDR)

The development of a science education that includes a focus upon the nature of science suggests the need for "pedagogic tools" that can be used to engage children with the procedural understandings that are central to the scientific approach to enquiry. This paper reports on a collaborative action research project that focused on the…
