The Story of Phoenix Quest: How girls respond to a prototype language and mathematics computer game

This article describes a case study of six girls' experiences with the Phoenix Quest computer game. In addition to the case study, a supplementary large-scale study of the reactions of both boys and girls to the same computer game was conducted for comparative analysis. Phoenix Quest (PQ) was designed not only to encourage children to explore language and mathematics, but also to offer game features that would especially appeal to girls. Participants in the case study were given opportunities to become acquainted with PQ for several months before being observed and interviewed. Four issues that emerged as being important to the participants were (a) presentation of the story in a non-linear format, (b) appreciation for the problem-solving elements of PQ, (c) identification with the main character (female), and (d) lack of awareness of the mathematics embedded within the game. The findings provided evidence that PQ appealed to girls because the protagonist was of their age and gender, and because the puzzles and searches were engaging throughout the game. Some aspects of the game, however, were less successful; for instance, the non-linear story format was disconcerting to all but one of the participants, and only one student identified the mathematics in the game structure. The large-scale study involved 41 boys and 57 girls, aged 8-12, from four junior school classes (Grades 4, 5 and 6). The aggregate data collected showed that more girls than boys used the postcard-writing feature of PQ and appreciated following the adventures of a female protagonist. More boys than girls were reported to offer advice to other students, discuss the game during their free time, and observe others playing the game. Some boys even formed groups to exchange information and game-playing strategies. Also, more boys than girls recognised the mathematics embedded within the game. Although these studies did not focus on teacher-student interaction, the finding that more than 25% of participating students were not able to identify the mathematics embedded in PQ, supports supplementary instruction on the part of a teacher as a requirement for making the mathematics more salient. Further research to address this issue is strongly recommended. Both the case study and the large-scale study revealed that among computer games, PQ's uncommon approach of celebrating and challenging a female protagonist is important to girls. This does not suggest that the presentation of a female protagonist will discourage boys from playing and enjoying the game. On the contrary, our findings showed that boys were also engaged by PQ, a game that encourages cooperative play and group problem-solving. In the realm of computer games, gender identification plays a key role, in first capturing the attention of girls, and then sustaining their interest, enjoyment and participation.     

Educational Attainment as Process: Using Hierarchical Discrete-Time Event History Analysis to Model Rate of Progress

Variables that address student enrollment patterns (e.g., persistence, enrollment inconsistency, completed credit hours, course credit load, course completion rate, procrastination) constitute a longstanding fixture of analytical strategies in educational research, particularly research that focuses on explaining variation in academic outcomes. However, nearly all measures of enrollment patterns are handicapped by untested assumptions about a more fundamental measure, namely students’ rate of progress. In this paper, I first explain how a variety of widely used measures of enrollment patterns are inextricably linked to students’ rate of progress. I then describe a method of modeling mathematically students’ rate of progress that employs hierarchical (multilevel) discrete-time event history analysis of repeated events. I conclude with an empirical example of the application of this method in which I test several hypotheses concerning students’ rate of progress through the remedial math sequence toward the outcome of college-level math competency. In addition to the utility of the method that is proposed here, the issues discussed in this paper have important practical implications for institutional research, particularly with respect to the use of the various measures of enrollment patterns to explain variation in students’ attainment.

The role of injection cues in the production of the morphine preexposure effect in taste aversion learning

The attenuation of an LiCl-induced conditioned taste aversion (CTA) by LiCl preexposure is mediated primarily by associative blocking via injection-related cues. Given that preexposure to morphine attenuates morphine-induced CTAs, it was of interest to determine whether injection cues also mediate this effect. Certain morphine-induced behaviors such as analgesic tolerance are controlled associatively, via injection-related cues. Accordingly, animals in the present experiments were preexposed to morphine (or vehicle) every other day for five total exposures, followed by an extinction phase, in which the subjects were given saline injections (or no treatment) for 8 (Experiment 1) or 16 (Experiment 2) consecutive days. All of the animals then received five CTA trials with morphine (or vehicle). The morphine-preexposed animals in Experiment 1 displayed an attenuation of the morphine CTA that was unaffected by extinction saline injections, suggesting that blocking by injection cues during morphine preexposure does not mediate this effect. All of the morphine-preexposed subjects in Experiment 2 displayed a weakened preexposure effect, an effect inconsistent with a selective extinction of drug-associated stimuli. The attenuating effects of morphine preexposure in aversion learning are most likely controlled by nonassociative mechanisms, like drug tolerance.     

Test–retest reliability of a battery of field-based health-related fitness measures for adolescents

Abstract

The main aim of this study was to determine the test–retest reliability of existing tests of health-related fitness. Participants (mean age 14.8 years, s = 0.4) were 42 boys and 26 girls who completed the study assessments on two occasions separated by one week. The following tests were conducted: bioelectrical impedance analysis (BIA) to calculate percent body fat, leg dynamometer, 90° push-up, 7-stage sit-up, and wall squat tests. Intra-class correlation (ICC), paired samples t-tests, and typical error expressed as a coefficient of variation were calculated. The mean percent body fat intra-class correlation coefficient was similar for boys (ICC = 0.95) and girls (ICC = 0.93), but the mean coefficient of variation was considerably higher for boys than girls (22.2% vs. 12.2%). The boys' coefficients of variation for the tests of muscular fitness ranged from 9.0% for the leg dynamometer test to 26.5% for the timed wall squat test. The girls' coefficients of variation ranged from 17.1% for the sit-up test to 21.4% for the push-up test. Although the BIA machine produced reliable estimates of percent body fat, the tests of muscular fitness resulted in high systematic error, suggesting that these measures may require an extensive familiarization phase before the results can be considered reliable.     

The effects of conditioned taste aversions on the acquisition and maintenance of schedule-induced polydipsia

Conditioned taste aversions produced a moderate, but transient, suppression of schedule-induced polydipsia. This suppression was greater and longer lasting when rats were offered a choice between water and the previously poisoned solution on the polydipsia baseline. A final experiment demonstrated that taste aversions were more effective in suppressing schedule-induced consumption when superimposed on a developing schedule-induced drinking baseline as opposed to a stable pattern of schedule-induced drinking. It was suggested that schedule-induced polydipsia is insensitive to conditioned taste aversions. This conclusion was discussed in terms of schedule-induced alcohol consumption and its potential as an animal model of alcoholism.     

Once Attained, Can Quality Child Care Be Maintained?

Research Findings: This study was designed to assess whether investments in child care quality were maintained 3 years after public funding for these centers was significantly reduced. An earlier evaluation documented significant improvements in classroom environments, teachers' sensitivity, and teachers' child-centered beliefs following a 15-month state intervention in 24 early care and education programs serving high numbers of children from low-income families. The current study used a quasi-experimental design, with pre- and postdata collected through direct observations and questionnaires in nonrandom treatment and comparison groups. Practice or Policy: Results at the 3-year follow-up showed that the majority (92%) of centers in the intervention group were accredited and that significant improvements in classroom environments were maintained after funding was significantly reduced. However, erosion in more sensitive measures (i.e., teacher sensitivity and child-centered beliefs) during the period of reduced funding suggested some concern that programs serving high concentrations of children from low-income families may require some consistent state support if they are to yield the positive life outcomes desired by economists and policymakers.
