The use of formal observation in primary mathematics classrooms is supported in the literature as a viable method of determining effective teaching strategies and appropriate tasks for inclusion in the early years of mathematics learning. The twofold aim of this study was to (a) investigate predictive relationships between primary mathematics…

Pharmacists, although not practicing chemists, often use skills and knowledge obtained in chemistry courses that are essential for success in their profession. This is especially apparent when preparing prescriptions for drugs that do not have a commercially available dosage form. Some well-publicized events indicate the potency of these drugs is…

Whether it is a rapid-fire Twitter event as part of #ASEchat, or BBC Radio 4's "Inside Science," the discussion of practical work generates powerful debate. While it is right that the best use of practical work is continually discussed, its value in science teaching is without question. The level of discussion is being further heightened…

Primary-aged children's decreasing enthusiasm for science is worrying. The author explores why children are often not as excited by science as one would expect. She found that the best way to counter this is to be enthusiastic about the subject herself, have interesting activities for the children to carry out, and give them a choice about what to…

Hands-on practical work in physics and engineering has a long and well-established tradition in Australian universities. Recently, however, the question of whether hands-on physics and engineering practicals are useful for engineering students and whether they could be deleted or whether these could be replaced with computer simulations has been…

Having students design their own methods regarding data collection during a lab may help them formulate appropriate investigative procedures. The authors use a modified gallery walk to develop science skills. (Contains 3 figures.)

In this article we examine teacher instruction on scientific literacy tasks and teacher expression of ultimate and subordinate purposes during one teaching sequence of a science unit. By using a Practical Epistemology Analysis and Systemic Functional Grammar we can provide a view of the direction learning takes and the consequences for student…

Cost-effective, easily replicated program is a win-win situation for high schoolers who teach science and for their elementary students. The thank-you letter from Leslie, a grade-schooler in San Diego County's Ramona Unified School District, speaks volumes about the excitement generated by "Celebrate Science"--an innovative,…

A hands-on, minds-on inquiry chemistry experiment was developed for use in K-12 schools that enables students to combine the chemicals of their choice and observe the results. The chemistry involved is water based and builds upon acid-base, double displacement, and iodometric detection of starch reactions. Chemicals readily available in the…

The classroom-friendly ABO blood type kit was developed by combining advantages of modelling and a simulation laboratory to teach the topics of ABO blood types and blood transfusion. Teachers can easily simulate the agglutination reaction on a blood type testing plate in the classroom, and show the students how this reaction occurs by using the…

In analytical chemistry classes, the importance of gathering a proper sample for analysis of bulk materials is often addressed only briefly or not at all. Although a number of classroom and laboratory exercises have been developed to illustrate factors that impact error introduced by sampling, they generally do not demonstrate the main goal of…

Illusionists use mirrors to create appearances that conflict with our notions of reality. This paper discusses an activity involving the Pulfrich effect that, in the end, makes use of a mirror to distinguish between appearance and reality.

Problem Statement: Research studies indicate that teachers with negative attitudes toward science tend to use didactic approaches rather than approaches based on students' active participation. However, the reviews of the national academic literature in Turkey located a few research studies on the relationship between playful science experiences…

Aboriginal children experience social and educational disadvantage and many are not engaged with schooling or learning, which results in significantly lower levels of educational attainment. The Aboriginal Education Program delivered by Scitech to remote Western Australian schools has been shown to significantly increase student ratings of their…

This article describes an after-school program at the Horace Mann School for the Deaf (HMS), the oldest public day school for deaf students in the United States, where almost half of the student body imagined and created bridge and robotic machines. The Deaf Robotics Engineering and Math Team, or the DREAM Team club, included HMS students in…
