Targeting, to aim a crosshair at an object, is the most basic skill for a gamer to survive from enemies, solve puzzles, and make a story unfolded in videogames. As the trigger for the game objects’ reciprocal operations, this simple action functions to individuate the objects kept in their abstract initial state into the concrete functional units participating in a topological network operational in a videogame to achieve the gamer’s goal. In today’s open-world games, these objects disclose their agencies through the auras perceivable when the player characters use certain magical skills and technological aids. In this genre, a gamer’s narrative and ludic experiences, all triggered by one’s performance to target at the objects on the human side of the interface, are translated, on the machinic side, into the topological transformations of the objects’ network. As an experiment for a nonhuman turn in videogame studies, this essay examines how this topological network behind an open-world mobilizes the ludic and narrative behaviors of gamers for its never-ending transformation. 相似文献

Korean middle school students are experiencing high rates of behavioral and emotional problems, suggesting a need for comprehensive screening instruments with strong psychometric properties in school settings. The present study investigated the utility of the Behavior Assessment System for Children‐2 Self‐Report of Personality, Adolescent Form (BASC‐2 SRP‐A) to assess clinical problems and adaptive strengths among Korean middle school students. For this revalidation study of the BASC‐2, we first translated the BASC‐2 SRP‐A into Korean (K‐BASC‐2 SRP‐A). Then, using a total of 458 Korean middle school students aged 12 to 15 years, we examined the factor structure and reliability of the clinical, adaptive, and composite scale scores of the K‐BASC‐2 SRP‐A. We also used a separate sample of 45 middle school students to examine the convergent validity of a subset of the K‐BASC‐2 SRP‐A scales targeting the common problem areas of anxiety, depression, and inattention. Based on the current results, we found strong psychometric properties of the K‐BASC‐2 SRP‐A for use among adolescents in Korea, including a well‐fitting factor structure consistent with the originally proposed model, adequate reliability estimates, and validity coefficients falling in the acceptable range. The K‐BASC‐2 SRP‐A can offer the Korean school mental health field a useful and much‐needed multidimensional screening measure for middle school youths. 相似文献

This study demonstrates that NVivo, a popular research tool for content analysis, produces biased Cohen’s kappa as it calculates the reliability statistic at the character level, which is unsuitable for most content-analytic studies adopting a higher unit of analysis (e.g., sentence, paragraph). Based on empirical data and a statistical simulation, this study proposes a method of bias correction applicable to situations where two independent raters conduct binary coding. 相似文献

Architectural heritages are exposed to natural and man-made disasters so that the need for research to prevent disasters has arisen. Cheomseongdae, known as the oldest astronomical observatory in East Asia, displays separation between the members and is tilted to the north-northeast. To diagnose the present conditions and to resolve problems, site investigations are performed. Boring is conducted in the surrounding ground of Cheomseongdae, and noninvasive investigations such as seismic tests and electrical resistivity surveys are conducted as well. The present study proposes a geotechnical engineering approach focused on noninvasive site surveys, and through this, relates current tilted condition of structure and provides information on the stability of Cheomseongdae. 相似文献

Scripted lesson plans and/or professional development alone may not be sufficient to encourage teachers to reflect on the quality of their teaching and improve their teaching. One learning tool that teachers may use to improve their teaching is Lesson Study (LS). LS is a collaborative process involving educators, based on concepts of iteration and revision, to improve instruction. The initial use of an adapted version of LS referred to as a microteaching lesson study (MLS) is described in this article. Our purpose is to illustrate the process of MLS used by a group of researchers when developing lesson plans for teaching students with learning disabilities. We describe MLS, and then (1) share an application of MLS used by a research team in developing a writing intervention, and (2) discuss how the MLS format was mirrored with K‐12 teachers during professional development training. 相似文献

Monte Carlo methods can be used in data analytic situations (e.g., validity studies) to make decisions about sample size and to estimate power. The purpose of using Monte Carlo methods in a validity study is to improve the methodological approach within a study where the primary focus is on construct validity issues and not on advancing statistical theory. The purpose of this study is to demonstrate how Monte Carlo methods can be used to determine sample size and to estimate power for a confirmatory factor analytic model under model-data conditions commonly encountered in exercise and sport. Because the purpose is pursued by way of demonstration with the Coaching Efficacy Scale II-High School Teams, related sample size recommendations are provided: N > or = 200 for the theoretical model; N > or = 300 for the population model. Technical terms (e.g., coverage) are defined when necessary. 相似文献

Whether hierarchical logistic regression can reduce the sample size requirement for estimating optimal cutoff scores in a course placement service where predictive validity is measured by a threshold utility function is explored. Data from courses with varying class size were randomly partitioned into two halves per course. Non-hierarchical and hierarchical analyses were performed on each half. Compared to their nonhierarchical counterparts, hierarchically estimated cutoff scores from different halves were more stable and predicted course outcomes in the other half more accurately. These differences were most pronounced with small samples. Sample size requirements for developing cutoff scores for course placement can be substantially reduced if hierarchical logistic regression is used. 相似文献

The purpose of this paper is to delineate several problems which arise when criterion-referenced test results are used to evaluate the effects of a specific educational treatment. Specifically, the paper deals with: (1) alternative methods of aggregating individual student and group data on objectives, (2) the sensitivity of the instrument to program outcomes, and (3) the comparisons of criterion-referenced test data and standardized (norm-referenced) achievement test data. 相似文献

Self-assessment is essential to scientific literacy as stated by the National Research Council Committee on Conceptual Framework for the New K-12 Science Education Standards and has since been incorporated into the Next Generation Science Standards. However, little empirical evidence documents which instructional tools are beneficial in improving students’ self-assessment in science learning. As such, we conducted a classroom-based quasi-experiment to test whether contrasting case-based instructional supports improved 390 introductory high school physics students’ accuracy in self-assessment and academic performance when solving physics problems. We compared the effects of providing students with content knowledge and contrasting cases (contrasting good and poor solution) on students’ physics problem solving and their ability to self-assess, with the effects of either presenting them with content knowledge and good solutions or teaching only content knowledge. We found contrasting examples improved the accuracy of students’ self-assessments, promoted content learning, and enhanced the development of self-assessment strategies. 相似文献

Child Care Teachers' Response to Children's Emotional Expression 总被引：1，自引：0，他引：1
This observational study examined practices through which child care teachers socialize children's emotion. A specific aim was to describe strategies of teacher intervention in response to emotion displayed by children in child care centers, and to answer the question of differential interactions based on children's age and gender.
The results of this study were as follows: (a) toddler teachers matched and encouraged children's positive emotion expression more often than did preschool teachers; (b) in response to children's negative emotion, toddler teachers used physical comfort and distraction more often than did preschool teachers who relied more on verbal mediation; (c) in response to girls' negative emotional expressions, teachers provided more physical comfort and distraction whereas they were more likely to provide boys with constructive ways to express negative emotion.
The results of this study also revealed relatively infrequent teaching about constructive ways of expressing negative emotion and very few occurrences of teacher's empathy, two developmentally appropriate methods for socializing emotion. Teachers may benefit from a training program focusing on facilitating emotional competence. 相似文献
