In this article, the authors report a case study where Blackboard's wiki function was used to create electronic lab books for the supervision of undergraduate students completing laboratory based research projects. This successful experiment in supervision using electronic notebooks provided a searchable record of student work and a permanent…

Lessons and homework problems involving a pendulum are often a big part of introductory physics classes and laboratory courses from high school to undergraduate levels. Although laboratory equipment for pendulum experiments is commercially available, it is often expensive and may not be affordable for teachers on fixed budgets, particularly in…

When a college instructor goes out of town and must miss a lecture, the standard options are to cancel the class meeting or to enlist a colleague to fill in. In the former case a teaching opportunity is lost; in the latter the substitute may not lead the class in the same way as the instructor. Some students routinely skip lectures by a guest…

By studying Antarctica via satellite and through ground-truthing research, we can learn where the ice is melting and why. The Landsat Image Mosaic of Antarctica (LIMA), a new and cutting-edge way for scientists, researchers, educators, students, and the public to look at Antarctica, supports this research and allows for unprecedented views of our…

Interactive simulations are entering mainstream science education. Their effects on cognition and learning are often framed by the legacy of information processing, which emphasized amodal problem solving and conceptual organization. In contrast, this paper reviews simulations from the vantage of research on perception and spatial learning,…

As a newcomer to the Department of Natural Sciences at University of Maryland-Eastern Shore (UMES) in fall 2007, assistant biochemistry professor Jennifer L. Hearne concluded from teaching "Principles of Chemistry I" that the introductory general education course needed a makeover. In addition to alleviating teaching inefficiencies,…

What impact can Web 2.0 technologies, specifically social networking sites, have inside and outside the classroom? While participation within the Facebook community has grown exponentially across college campuses, participation in course-specific WebCT discussion forums has not necessarily followed suit. In response to this disparity, Jacob…

The formation constant of iron(III) complex with glycine (Gly) ligand in aqueous acidic medium (0.2 M HNO[subscript 3], I = 0.2 M at 28 plus or minus 1 degree C) was determined spectrophotometrically in which a competing color reaction between Fe(III) and SCN[superscript -] was used as an indicator reaction. Under the specified conditions Fe(III)…

Dynamic visualizations of scientific phenomena have the potential to transform how students learn and understand science. Dynamic visualizations enable interaction and experimentation with unobservable atomic-level phenomena. A series of studies clarify the conditions under which embedding dynamic visualizations in technology-enhanced inquiry…

Many students arrive at high school with enthusiasm for learning Science but by Year 9 some students have become disengaged with Science as a subject. In an attempt to find out the reasons for this, thirty-five Year 9 students from five South Australian secondary schools participated in focus group discussions. This research unearthed a number of…

This study used an online peer assessment activity to help 47 college students to learn biology through writing. Each student submitted a biology writing report to an online system and then experienced three rounds of peer assessment. During the online peer assessment process, self, peer and expert evaluation scores for the writing were gathered…

The advent of technology is almost in the field of education for teaching -- learning and cannot be ignored. Students are exposed to superior quality product of advance technologies in other fields around them. In such a scenario whether chalk and black board education is relevant in today's multicoloured and multidimensional digital age? The…

The virtual laboratories developed by a life sciences department at a public university in the US were designed for use by college students enrolled in an introductory biology course. The results analyses conducted to examine their effectiveness indicated that self-selected users of the virtual laboratories outperformed non-users on laboratory…

Students learn about physical laws and the scientific method when they analyze experimental data in a laboratory setting. Three common sources exist for the experimental data that they analyze: (1) "hands-on" measurements by the students themselves, (2) electronic transfer (by downloading a spreadsheet, video, or computer-aided data-acquisition…

It has long been known that when a cable of specified length is hung between two poles, it takes the shape of a catenary--a hyperbolic cosine function. In this paper, we study a variation of this problem. First, we consider a cable hanging between two poles in which one end of the cable is fixed to one pole; the other end of the cable runs over a…
