Haverly, Christa; Sedlmeyer, Kim – Science and Children, 2019
Formative assessments serve to engage students in active sense-making, making them critical tools for both teachers and students. Though formative assessments may be an informal mode of assessing, they are one of the most important, especially when teaching science. As a subject, teaching science does not have the same kind of beginning-middle-end…

Heissel, Jennifer; Norris, Samuel – Education Next, 2019
American teenagers are chronically sleep deprived. As children enter puberty, physiological changes delay the onset of sleep and make it more difficult to wake up early in the morning. By the end of middle school, there is a large disconnect between biological sleep patterns and early-morning school schedules: one study found that students lose as…

Chiras, Andreas – Science Education International, 2008
The study investigated the mental models of primary school children related to the day/night cycle. Semi-structure interviews were conducted with 40 fourth-grade and 40 sixth-grade children. Qualitative and quantitative analysis of the data indicated that the majority of the children were classified as having geocentric models. The results also…

Lyons, Lisa C.; Roman, Gregg – Learning & Memory, 2009
Endogenous biological clocks are widespread regulators of behavior and physiology, allowing for a more efficient allocation of efforts and resources over the course of a day. The extent that different processes are regulated by circadian oscillators, however, is not fully understood. We investigated the role of the circadian clock on short-term…

Schwarz, Baruch B.; Schur, Yaron; Pensso, Haim; Tayer, Naama – International Journal of Computer-Supported Collaborative Learning, 2011
Changing practices in schools is a very complex endeavor. This paper is about new practices we prompted to foster collaboration and critical reasoning in science classrooms: the presentation of pictures representing different perspectives, small group synchronous argumentation, and moderation of synchronous argumentation. A CSCL tool helped in…

Tao, Ying; Oliver, Mary; Venville, Grady – Cultural Studies of Science Education, 2013
The purpose of this study was to explore Chinese and Australian primary children's conceptual understandings of the Earth. The research was conducted in the interpretive paradigm and was designed to be descriptive with comparative and cross sectional elements. Participants were Year 3 and Year 6 children from three schools in Hunan Province,…

Parslow, Graham R. – Biochemistry and Molecular Biology Education, 2012
Teaching by night and reflecting on a subject by day is the way that Salman Khan sees education evolving in the age of online lectures. Khan believes he is onto something in what he styles the "flipped classroom." In Khan's view, there is no need for students to be divided into grades by age. Instead, they should learn at their own pace, moving on…

Watson, John; Gemin, Butch – International Association for K-12 Online Learning, 2009
In at least 44 states across the country, students are logging in to learn at all times of the day and night--accessing courses they might otherwise be unable to take, interacting with students they might otherwise never know, and working with highly qualified teachers they otherwise could not access. In these and countless other ways, online…

Dove, Jane – International Journal of Science Education, 2002
Analyzes the answers provided by (n=98) 12-year-old students to questions on an end-of-the-year science examination. Points out that although students are able to explain day and night, they have difficulties explaining why the moon always presents the same face to Earth. Addresses implications for teaching and learning. (Contains 17 references.)…

Siegal, Michael; Butterworth, George; Newcombe, Peter A. – Developmental Science, 2004
In this investigation, we examined children's knowledge of cosmology in relation to the shape of the earth and the day-night cycle. Using explicit questioning involving a choice of alternative answers and 3D models, we carried out a comparison of children aged 4-9 years living in Australia and England. Though Australia and England have a close…

Miles, Barbara; McLetchie, Barbara – National Consortium on Deaf-Blindness, 2008
In children, concepts develop in a spiral, with the child at the center. A positive self-concept begins within a responsive caregiving environment. Concepts build upon one another. The more ideas and memories that a child has about the way the world and relationships work, the easier it is to develop further ideas. Once a child realizes, for…

Roald, Ingvild; Mikalsen, Oyvind – International Journal of Science Education, 2001
Reports and analyzes the day and night cycle, the seasons, and the phases of the moon as seen by Norwegian deaf pupils aged 7, 9, 11, and 17 years, and by hearing Norwegian pupils 9 years old. Among the 9-year-olds there was no difference in the inner coherence of the conceptions between deaf pupils. (Author/SAH)

Gazit, Elhanan; Yair, Yoav; Chen, David – Journal of Science Education and Technology, 2005
This study describes high school students' conceptual development of the basic astronomical phenomena during real-time interactions with a Virtual Solar System (VSS). The VSS is a non-immersive virtual environment which has a dynamic frame of reference that can be altered by the user. Ten 10th grade students were given tasks containing a set of…
