A multi-instrument approach has been applied to the efficient identification of polymers in an upper-division undergraduate instrumental analysis laboratory course. Attenuated total reflectance Fourier transform infrared spectroscopy (ATR-FTIR) is used in conjunction with differential scanning calorimetry (DSC) to identify 18 polymer samples and…

At the beginning of the nineteenth century, the core of a typical teaching collection was composed by apparatus, which were very similar to the ones proposed in the eighteenth century by 's Gravesande, Nollet, Desaguliers and others lecturer demonstrators and makers. Since 1820 circa, new didactic instruments were introduced. Most of them…

The prevailing tendency in modern university reforms is towards "how people learn," following a learner-centered approach in which the learner is the main actor of the teaching-learning process. As a consequence, one of the key indicators of the teaching-learning process is the measurement of learner satisfaction within the classroom.…

Attempts to identify and characterize patterns of expert teaching practice as they occur in context, and to confirm these patterns through processes of verification. Observes teacher Dorothy DeLay in her studio, documenting her teaching through notes, audiotapes, and contextual artifacts. Discusses DeLay's theory of proximal positioning in…

Discussed are two techniques that can be used to directly test the theory that the plates which make up the crust of the earth are still moving. Described are the use of satellite laser ranging and very long baseline interferometry. Samples of data and their analysis are provided. (CW)

These three papers are from a symposium on new perspectives in human resource development (HRD). "Developing an Instrument to Measure the Use of Play-Based Training Methods in Healthcare Education" (Rebecca J. Adams, Karen E. Watkins, Tom Valentine) reports preliminary findings from a pilot study that tested data collection procedures…

Attempts to identify and describe the characteristics of effective teaching in the piano studio. Videotaped lessons with independent piano teachers and students were evaluated according to specific behavioral measures (general approval, music talk) and separately by pedagogical measures. Includes statistical and tabular data. (MJP)
