Core concepts can be integrated throughout lower-division science and engineering courses by using a series of related, cross-referenced laboratory experiments. Starting with butane combustion in chemistry, the authors expanded the underlying core concepts of energy transfer into laboratories designed for biology, physics, and engineering. This…

Many general physics laboratories involve the use of springs to demonstrate Hooke's law, and much ado is made about how this can be used as a model for describing the elastic characteristics of materials at the molecular or atomic level. In recent years, the proliferation of computers, and appropriate sensors, have made it possible to demonstrate…

This research surveyed 11 purposely sampled Bindura University of Science Education (Zimbabwe) Bachelor of Science Education Honours Part III pre-service science teachers' use of improvised and virtual laboratory experimentation in science teaching. A self-designed four-point Likert scale twenty-item questionnaire was used. SPSS Version 10 was…

The field of training has been changing rapidly due to advances in technology such as videogame-based adaptive training. Videogame-based adaptive training has provided flexibility and adaptability for training in cost-effective ways. Although this method of training may have many benefits for the trainee, current research has not kept up to pace…

(Purpose) This article describes the use of tiered instruction, a specific form of differentiation, within the author's high school Physics classroom. A background and discussion on the nature of tiered instruction is also included. (Findings) Topics addressed in this paper include: (1) the necessity of differentiation within the classroom; (2)…

The topic of coupled oscillations is rich in physical content which is both interesting and complex. The study of the time evolution of coupled oscillator systems involves a mathematical formalization beyond the level of the upper secondary school student's competence. Here, we present an original approach, suitable even for secondary students, to…

The increase in publications presenting molecular evolutionary analyses and the availability of comparative sequence data through resources such as NCBI's GenBank underscore the necessity of providing undergraduates with hands-on sequence analysis skills in an evolutionary context. This need is particularly acute given that students have been…

The microbial growth curve is widely studied within microbiology classes and bacteria are usually the microbial model used. Here, we describe a novel laboratory protocol involving flow cytometry to assess the growth dynamics of the unicellular microalgae "Isochrysis galbana." The algal model represents an appropriate alternative to…

In this activity, students use a model created from a coffee cup or cardstock cutout to explore the working principle of an atomic force microscope (AFM). Students manipulate a model of an AFM, using it to examine various objects to retrieve topographic data and then graph and interpret results. The students observe that movement of the AFM…

The purpose of this article is to provide teachers, tutors and parents with an effective and enjoyable approach to practicing reading fluency, increasing comprehension and encouraging the joy of reading, based on the theories and methods of Sally L. Smith. This method can be applied and adapted to individual student's needs. Sally Smith, the…

Tutoring and conferencing have assumed important instructional roles as composition theory and practice have shifted from product-centered to process-centered approaches. The benefits of conferencing (Reigstad), of peer tutoring (Bruffee), of professional tutoring (Franke), and of group collaboration (Nystrand) have been presented and supported.…

Laboratory-based learning allows students to experience bioscience principles first hand. In our experience, practical content and equipment may have changed over time, but teaching methods largely remain the same, typically involving; whole class introduction with a demonstration, students emulating the demonstration in small groups, gathering…

It's always hard to know what to expect when bringing computers into an educational setting, as things are always changing. Student skills with computers are different today than they were 10 years ago, and 20 years ago almost counts as an alien world. Still, one hopes that some of these changes result in positive trends, such as student attitudes…

Good observations are often fundamental to good science, and drawing has long been recognized as a tool to develop students' observation skills. Yet when drawing in illustrated journals was introduced into botany laboratories in an undergraduate, teaching-focused university, students reported feeling uncomfortable and intimidated by the required…

Purpose: Academic writing is often considered to be a weakness in contemporary students, while good reporting and writing skills are highly valued by graduate employers. A number of universities have introduced writing centres aimed at addressing this problem; however, the evaluation of such centres is usually qualitative. The paper seeks to…
