As part of a multidisciplinary course that is cross-listed between five departments, we developed an undergraduate student laboratory experiment for culturing, isolating, and purifying the biopolymer, poly(3-hydroxybutyrate), PHB. This biopolyester accumulates in the cytoplasm of bacterial cells under specific growth conditions, and it has…

Individual genome DNA was extracted fast from oral swab and followed up with PCR specific for codon 248 of "p53" tumor suppressor gene. "Msp"I restriction mapping showed the G-C mutation in codon 248, which closely relates to cancer susceptibility. Students learn the concepts, detection techniques, and research significance of point mutations or…

The method given in many publications for calculating the solubility product of potassium bitartrate is wrong in principle. A way of modifying the experimental approach and calculations to overcome the problem are presented.

The purpose of this study was to identify and analyze patterns of institutional strategies and processes that promote the sustainability of laboratory schools housed and managed by institutions of higher education. First, a comprehensive analysis of the development, growth, decline, and current status of the laboratory school movement was…

Discusses precaution in handling laboratory chemicals and research animals. Gives references, suggested readings, and a table showing fire hazard properties of some flammable liquids. (MLH)

The roles of teachers and students are changing, and there are undoubtedly ways of learning not yet discovered. However, the computer and software technology may provide a significant role to identify the problems, to present solutions and life-long learning. It is clear that the computer based educational technology has reached the point where…

The undergraduate Bioengineering Program at Lehigh University was established as part of the university's Bioscience and Biotechnology Initiative with support from the National Science Foundation through a grant from its Division of Engineering Education and Centers (EEC). The objective here is to describe the program development and…

The purpose of this study was not only to report the development process of the studio model, but also to determine the students' perceptions about the studio model. This model retains the large lecture component but combines recitation and laboratory instruction into studio model. This research was based on qualitative analysis. The data of the…

This paper presents the rules and guidelines of the Intel International Science and Engineering Fair 2011 to be held in Los Angeles, California in May 8-13, 2011. In addition to providing the rules of competition, these rules and guidelines for conducting research were developed to facilitate the following: (1) protect the rights and welfare of…

Greater Clark Schools in Indiana enrolled with a STEM education program, Shining Star with Indiana University, integrated Nova 5000 data-loggers in their curriculum reported success improving students' standardized exam scores and interest in science and mathematics courses after a three year period. The success of the data-loggers, determined by…

This project questions a core value that writing center workers have long held about tutoring writing: that we change writers. Applying sociocognitive and Bakhtinian lenses, I was able to complicate theory-practice connections. Tutor-tutee negotiations during tutorials, tutees' perceived learning outcomes, and their revisions were compared with…

In this paper, the literature related to the use of technology in the languages classroom will be explored. In relation to the teaching and learning methodologies and approaches past and present as well as current research, comparisons are made between the audio-lingual/visual classroom and the digital classroom by way of describing and comparing…

We describe an alternative educational approach for an inorganic chemistry laboratory module named "Experimentation in Chemistry", which is included in Industrial Engineering and Chemical Engineering courses. The main aims of the new approach were to reduce the high levels of failure and dropout on the module and to make the content match the…

The maximal rate of O[subscript 2] consumption (VO[subscript 2max]) constitutes one of the oldest fitness indexes established for the measure of cardiorespiratory fitness and aerobic performance. Procedures have been developed in which VO[subscript 2max]is estimated from physiological responses during submaximal exercise. Generally, VO[subscript…

Forty-eight new secondary science teachers participated in a study that required a listing, discussion, and application of criteria to rank three chemistry laboratory procedures. The three similar lab procedures involved synthesis of a compound from its elements. The top criteria noted by teachers focused on procedural issues (i.e., timeliness,…
