Within the framework of the Lisbon Agreement, all European member states are encouraged to take measures to increase the number of science and technology students in higher education. To promote this educational model, a chemistry project was developed that focuses on high school students and especially on the involvement of their teachers by…

Maps such as concept maps and knowledge maps are often used as learning materials. These maps have nodes and links, nodes as key concepts and links as relationships between key concepts. From a map, the user can recognize the important concepts and the relationships between them. To build concept or knowledge maps, domain experts are needed.…

Recent educational policies, national reports, and voluminous literature stress that critical thinking (CT) is an essential skill in any stage of schooling for producing critical thinkers and ensuring better learning. The importance of teaching CT has been raised in teacher education programmes because students are supposed to teach this skill in…

This study aimed to apply Speech to Text Recognition (STR) for individual oral presentations and group discussions of students in a synchronous cyber classroom. An experiment was conducted to analyze the effectiveness of applying STR on learning performance. Students' perceptions and behavioral intentions toward using STR were also investigated.…

The need for interdisciplinary graduate training programs which prepare students to conceptualize the application of their research in clinical settings continues to grow. Though several programs have been cultivated to address this need, demand still outweighs supply. The following describes a curriculum developed with the intent of incorporating…

"Visualization" of chemical phenomena often has been limited in the teaching laboratories to the sense of sight. We have developed chemistry experiments that rely on senses other than eyesight to investigate chemical concepts, make quantitative determinations, and familiarize students with chemical techniques traditionally designed using only…

We report a school project which equips students with both theoretical and practical knowledge in material physics. We construct dumpling skins from a mixture of flour and water. A series of experiments is then conducted to quantify the toughness, hardness, and tensile strength of the skins, and how they are affected by adding other materials into…

In this study, we examined the effects of interference and repeated retention tests by comparing groups that performed (a) one or two tests, or (b) two tests separated by interpolated tasks. The task involved pressing five keys in 925 ms. Constant error increased after Block 1 of the second test for the group completing the interpolated tasks.…

An experimental learning module has been developed to study the mass and energy balance involved with operation of an AA Alkaline battery under a load current. An extension of the module allows evaluation of laboratory-assembled batteries using granular anodic/cathodic materials. The system allows load resistance to be varied and measures voltage…

We describe our experience in guiding a physics laboratory in the eleventh grade of a high school, in which regular laboratory classes are replaced by an experimental project carried out throughout the year. Some didactic suggestions and hints are given for those wishing to adopt such an undertaking. Outlines are given for a few of the recent…

A recent article showed how the influx of neodymium magnets has provided striking demonstrations of the interactions between magnets and conductors. The "shaking torch" is yet another example. Many of these torches require no batteries and can be submerged in water--indeed, a light for life. In this article, the author disassembles a shaking torch…

This research was designed to test the predictions of 2 approaches to perception. By most traditional accounts, people are thought to derive general-purpose spatial perceptions that are scaled in arbitrary, unspecified units. In contrast, action-specific approaches propose that the angular information inherent in optic flow and ocular-motor…

An electrochemical experiment is presented to illustrate biosorption to second-year and upper-division undergraduate students. The extraction of Cd[superscript 2+], Pb[superscript 2+], and Cu[superscript 2+] by nonliving "Typha latifolia" (cattail) roots can be monitored in real time by potentiometry determinations. The open circuit potential…

A first-year laboratory experiment that utilizes concepts of electrochemical tip etching for scanning tunneling microscopy (STM) is described. This experiment can be used in conjunction with any STM experiment. Students electrochemically etch gold STM tips using a time-efficient method, which can then be used in an instructional grade STM that…

Visual peripersonal space (i.e., the space immediately surrounding the body) is represented by multimodal neurons integrating tactile stimuli applied on a body part with visual stimuli delivered near the same body part, e.g., the hand. Tool use may modify the boundaries of the peri-hand area, where vision and touch are integrated. The neural…
