When students complete a lab experiment at home or in a staffed lab on campus, they come to class better able to explain what they have done and why they think the approach is correct, and to provide explanations or questions about any problems they encountered. What is so cool is that the learning experience has all the key aspects of the…

This study aims to investigate the relationships among epistemological beliefs, metacognitive awareness, and nature of science (NOS). Participants were 45 preservice science teachers (PSTs) enrolled in two sections of Laboratory Application in Science II course in a university in Turkey. All of the participants were juniors with the same science…

The development of education libraries cannot be understood outside the context of education history. Changes in educational practices and technology spurred three phases of development in the history of education libraries. Early examples, often called curriculum laboratories, developed as spaces to create educational materials where limited…

Human cadaveric tissue is the fundamental substrate for basic anatomic and surgical skills training. A qualitative assessment of the use of human cadavers preserved by Thiel's method for a British Association of Urological Surgeons--approved, advanced laparoscopic renal resection skills training course is described in the present study. Four…

Trees transport water from roots to crown--a height that can exceed 100 m. The physics of tree hydraulics can be conveyed with simple fluid dynamics based upon the Hagen-Poiseuille equation and Murray's law. Here the conduit structure is modelled as conical pipes and as branching pipes. The force required to lift sap is generated mostly by…

On many college campuses, the 21st century classroom is the exception rather than the norm. Here's what usually happens: A forward-thinking administrator pushes for a pilot program to redesign a handful of classrooms. The resulting learning spaces are cutting edge and successful--in high demand among faculty and students alike. And that's as far…

Teacher practices are essential for supporting learners in scientific inquiry practices of framing research questions, designing and conducting investigations, collecting data, and drawing conclusions. This study examines instructional practices of two Grade 11 Physical Science teachers engaged in teaching practical investigations. Data were…

Evidence suggests that student engagement in the material they are studying correlates well with better learning outcomes, and instrumental analysis modules structured to reflect student interests are of wide significance. The analysis of levels of dietary (Cu, Fe, Mn, Zn) and undesirable (Cd and Pb) metals in commercially available and wild…

A laboratory experiment is described to determine the primary current distribution in parallel-plate electrochemical reactors. The electrolyte is simulated by conductive paper and the electrodes are segmented to measure the current distribution. Experiments are reported with the electrolyte confined to the interelectrode gap, where the current…

Nanoporous zeolite foam is an interesting crystalline material with an open-cell microcellular structure, similar to polyurethane foam (PUF). The aluminosilicate structure of this material has a large surface area, extended porosity, and mechanical strength. Owing to these properties, this material is suitable for industrial applications such as…

This study examines the relevance of doctoral training (thesis, coursework and generic skills) for a career in three types of labour market: academia, applied research institutes and industrial laboratories, and non-research workplaces. Data are drawn from a mail survey among PhD holders in Norway. In total, more than 40% of the respondents had…

We examined independent and interactive associations linking preadolescents' socially anxious feelings and peer victimization experiences with their social behaviors (rated by parents and teachers) and psychophysiological arousal during lab simulations of salient peer stress situations in preadolescence (peer evaluation and peer rebuff).…

A number of scientific articles report on the use of natural extracts from plants as chemical reagents, where the main objective is to present the scientific applications of those natural plant extracts. The author suggests that natural reagents extracted from plants can be used as alternative low cost tools in teaching chemical analysis,…

The one-on-one format of tutoring, which is the norm for "writing" centers, can foster the much-maligned view of a "writing center" as a fix-it shop and undermine the role of the tutor as a co-learner and facilitator of peer-to-peer interactions. The peer-interactive "writing center approach", presented here, moves…

This study examined to what extent inquiry-based instruction supported with real-time graphing technology improves fourth grader's ability to interpret graphs as representations of physical science concepts such as motion and temperature. This study also examined whether there is any difference between inquiry-based instruction supported with…
