Assessing giftedness with the WISC‐III and the SB‐IV

The Wechsler Intelligence Scale for Children–Third Edition (WISC‐III) and the Stanford‐Binet Intelligence Scale–Fourth Edition (SB‐IV), were administered to 20 gifted children and 20 non‐gifted children to examine the extent of the difference in IQ scores obtained on the two tests and whether order effects were present. Results show that the SB‐IV Composite Score was significantly higher than the WISC‐III Full Scale IQ for both groups. However, for the gifted group, unlike the non‐gifted group, this difference achieved significance only when the SB‐IV was administered first. When either IQ test was administered to the gifted students for the first time, without the confound of a learning influence, there was no significant difference in mean scores. However, when both tests were administered, it was found that the SB‐IV influenced the WISC‐III Full Scale IQ in a downward direction whereas the WISC‐III influenced the SB‐IV Composite Score in an upward direction. © 2002 Wiley Periodicals, Inc.     

A path-dependence perspective on the adoption of Internet of Things: Evidence from early adopters of smart and connected sensors in the United States

As an integral part of the Internet of Things (IoT), smart and connected sensors are emerging information and communication technologies that collect and transmit real-time data from various urban domains to inform decision-making. While smart sensors and IoT technologies have great potential to transform public service provision, their adoption in the public sector seems to be slow and incremental. Using cross-sectional data of 65 large and mid-sized cities in the United States, we examine what affects local governments' adoption of smart and connected sensors. We propose a path-dependence explanation for the incremental adoption and test if a local government's sensor adoption behavior is shaped by its existing policy priorities and managerial practices in related fields. Our results show that local governments' early adoption of smart sensors is likely to stem from their needs in specific policy domains. We also find that a local government's historical paths on urban sustainability and data-driven decision-making practices can predict its trajectory of sensor deployment, in terms of the scope and the integration of smart sensors across different urban domains. Surprisingly, a local government's e-government progressiveness is not a significant predictor. Our results confirm the incremental change in smart sensor adoption and provide implications for local governments' IoT planning.     

What does playing cards have to do with science? A resource-rich view of African American young men

The study examines the resources related to science that African American young men learn and develop by playing a card game called Spades, a common cultural practice in African American communities that dates back to the Civil War Era. The qualitative study examines what the Spades players at a local high school consider when making decisions about what cards to play. A significant finding is that the players use, learn and develop resources such as the ability to make observations, draw inferences, and use empirical data to inform future actions and decisions. Such reasoning bears a resemblance to central practices of science and challenges long held deficit views of African American young men. Implications of the research findings are discussed.     

The effects of computer-assisted instruction and locus of control upon preservice elementary teachers' acquisition of the integrated science process skills

The purpose of this study was to determine the effects of computer-assisted instruction (CAI) versus a text mode of programmed instruction (PI), and the cognitive style of locus of control, on preservice elementary teachers' achievement of the integrated science process skills. Eighty-one preservice elementary teachers in six sections of a science methods class were classified as internally or externally controlled. The sections were randomly assigned to receive instruction in the integrated science process skills via a microcomputer or printed text. The study used a pretest-posttest control group design. Before assessing main and interaction effects, analysis of covariance was used to adjust posttest scores using the pretest scores. Statistical analysis revealed that main effects were not significant. Additionally, no interaction effects between treatments and loci of control were demonstrated. The results suggest that printed PI and tutorial CAI are equally effective modes of instruction for teaching internally and externally oriented preservice elementary teachers the integrated science process skills.     

Home cage feeding time controls responding under multiple schedules

Eleven rats were exposed to a multiple variable-interval 1-min variable-interval 1-min schedule of reinforcement. All rats were initially fed a daily ration of food in the home cages immediately after the end of each session. In a later phase of the experiment, the same amount of food was fed 1 h after the end of each session. Later, five rats were again fed immediately after each session. Amount of food received and deprivation level in terms of percent of free feeding weight were constant across conditions. Response rates decreased within each session under immediate feeding. When feeding was delayed, rates in each component of the multiple schedule increased throughout the session and the decreasing trends were generally eliminated. The results suggest that home cage feeding time, apart from changes in deprivational level, is an important variable in the control of behavior in experimental sessions.     

Do German-speaking children have a chance to overcome reading and spelling difficulties? A longitudinal survey from the second until the eighth grade

In a longitudinal study the development of reading and spelling abilities of 458 Viennese school children from the second until the eighth grade was analysed. Although the students’ level of performance displayed a great consistency with poor readers and spellers retaining their weaknesses, groups of students whose performance either improved or deteriorated with time were also identified. Not only cognitive prerequisites, but also the classroom behavior of the students and social factors proved to be significant for the long-term prognosis.     

Sense of community in a higher education television-based distance education program

The purpose of this study was to measure sense of classroom community in a television-based higher education distance education course and in the same course taught by the same instructor in a traditional face-to-face learning environment, in order to determine if differences existed and if so to identify the nature of these differences. Participants for this study consisted of 120 adult learners who were enrolled in either of two sections of a semester-long undergraduate educational technology course offered by an urban state university. One section was taught tradiationally and the other section was taught to a small studio audience and at a distance to 24 remote classroom sites using synchronous one-way television and two-way audio technologies. Study results revealed a significantly lower sense of classroom community among learners in the distance education course, to include the studio audience.     

Peer Mentoring Styles and Their Contribution to Academic Success Among Mentees: A Person-Oriented Study in Higher Education

The purpose of our study was to explore peer mentoring styles and examine their contribution to academic success among mentees. Data were collected as part of a comprehensive evaluation of a peer mentoring program. The sample consisted of 49 mentors (advanced students) who supported 376 mentees (first year students) in small groups. Indicators for peer mentoring styles were constructed using mentee assessments of mentoring functions and mentor quality, and unobtrusive data gathered in an analysis of online mentoring activities and a content analysis of the quality of the online mentoring activities. Using cluster analyses, three distinct mentoring styles were identified: Motivating master mentoring, informatory standard mentoring, and negative minimalist mentoring. Motivating master mentors were shown to have a positive influence on success in the mentoring program among those mentees who failed two preliminary exams. Implications for the training of peer mentors in higher education are discussed.
