Students in several sections of a theory of arithmetic course at Arizona State University were given instruction with a laboratory approach based on structural manipulative models. Their attitudes and achievement were compared with those of students receiving instruction with lectures and a textbook. The students who used the manipulative models had more favorable attitudes toward mathematics than the other group. However, they were not able to cover as much content and did not have as much measured achievement.

The purpose of this study was to describe and analyze systematically the coaching behaviors of more and less successful high school boys’ tennis coaches during practice sessions. The Arizona State University Observation Instrument, consisting of 14 behavior categories, was used to compile data on nine coaches (five judged as more successful and four judged less successful, based on win records). Time sampled event recording was used to collect the data, with each coach being observed during preseason/early season, midseason, and late season for a total of three observations per coach. Analysis of the data showed that the more successful coaches asked a significantly greater number of questions of their players than did the less successful coaches. The tennis coaches demonstrated more instructional behaviors than any other behavior but spent more intervals in the Other category than in any other behavioral category. Other, Management, and Silence accounted for almost 75% of all intervals.

The Mathematics Learning Clinic at Arizona State University gives teachers experience in a clinical approach to the mastery of diagnostic/corrective theories and techniques of classroom mathematics instruction. The clinic also provides diagnostic/prescriptive help to a limited number of children experiencing difficulty in learning mathematics. For additional information contact Jon M. Englehardt, Mathematics Learning Clinic, College of Education, Arizona State University, Tempe, AZ 85281.

3D unsteady computational fluid dynamics analyses were performed for both close-spaced and wide-spaced turbine stages with axial gap seals and a cavity. Turbine stages, with airfoil configurations similar to those previously studied at United Technologies Research Center (UTRC) and Arizona State University (ASU), were simulated for vane-blade spacing at 34 percent and 70 percent of the vane axial chord length, L. Three configurations were investigated, with the first one placing an axial gap rim seal at 17 percent L upstream of the blade for close-spaced stage, and the other two placing the axial gap seal at either 17 or 34 percent L upstream of the blade for the wide-spaced stage. The seal velocity ingestion characteristics were strongly dependent on axial location for the wide-spaced stage. The seals placed at equal distances upstream of the blade leading edge for the wide- and close-spaced stages had approximately the same average ingestion velocity characteristics. However, the ingestion velocity profiles for the wide-spaced stage were less influenced by vane wakes than for the close-spaced stage. The calculated variation of radial velocity in all gaps was consistent with previous tangential and radial velocity measurements in the seal gap measurements at the University of Aachen.

A new field emission scanning transmission electron microscope has been constructed for the NSF HREM facility at Arizona State University. The microscope is to be used for studies of surfaces, and incorporates several surface-related features, including provision for analysis of secondary and Auger electrons; these electrons are collected through the objective lens from either side of the sample, using the parallelizing action of the magnetic field. This collimates all the low energy electrons, which spiral in the high magnetic field. Given an initial field Bi∼1T, and a final (parallelizing) field Bf∼0.01T, all electrons emerge into a cone of semi-angle θf≤6°. The main practical problem in the way of using this well collimated beam of low energy (0-2keV) electrons is that it is travelling along the path of the (100keV) probing electron beam. To collect and analyze them, they must be deflected off the beam path with minimal effect on the probe position.

The standard ASUDAS scoring system (Arizona State University Dental Anthropology System) is used to assess dental morphological variations in modern humans. It is also frequently used to study, score, and compare morphological variations in fossil hominin taxa and to examine their phylogenetic relationships. However, using ASUDAS in studies of this type is under debate because it is based on modern Homo sapiens populations and does not appear to cover all variations observed in fossil Plio-Pleistocene homi- nins. Our observations and coding of 178 dentals casts of Plio-Pleistocene specimens based on ASUDAS and from the literature have confirmed the need to adapt the standard system to fossil hominins. In this initial study, we propose that the scoring procedures for some morphological characters need to be readjusted, while others could be standardized following the ASUDAS system.

<span>La investigación en torno a las concepciones alternativas (Wandersee, Mintzes, y Novak, 1994; Arizona State University, 2001; Flores, 2002) constituye una de las principales y fecundas líneas de investigación en Didáctica de las Ciencias que ha contribuido, en buena medida, a su surgimiento y consolidación como disciplina o campo de conocimiento (Gil, 1994; Adúriz-Bravo e Izquierdo, 2002).
