The authors present the methodological background to and underlying research design of an ongoing research project on the scientific evaluation of serious games and/or computer‐based simulation games (SGs) for advanced learning. The main research questions are: (1) what are the requirements and design principles for a comprehensive social scientific methodology for the evaluation of SGs?; (2) to what extent do SGs contribute to advanced learning?; (3) what factors contribute to or determine this learning?; and (4) to what extent and under what conditions can SG‐based learning be transferred to the real world? In the Netherlands between 2005 and 2012, several hundred SG sessions with 12 SGs were evaluated systematically, uniformly and quantitatively to create a dataset, which comprises data on 2488 respondents in higher education or work organizations. The authors present the research model, the quasi‐experimental design and the evaluation instruments. This focus in this paper is on the methodology and dataset, which form a sound foundation for forthcoming publications on the empirical results. 相似文献

Reading is an essential activity for learning at university, but lecturers are not always experienced in setting appropriate questions to test understanding of texts. In other words, their assessments may not be ‘constructively aligned’ with the learning outcomes they hope their students to exhibit. In examination conditions, questions may be set with insufficient time for re-reading available texts, thus drawing more on students' powers of recall than on deeper learning and comprehension. Previous research has been undertaken on reading comprehension generally, but no research has yet explored the interaction of factors such as text availability (re-reading of texts), text layout, question type and respondents' language background. This study explores the correctness of 50 participants' responses to a set reading task based on an expository text, and participants' confidence in giving those answers, in relation to four factors: the effects of question type; text availability; text layout; and language background. The main findings are that non-native speakers of English have more difficulty and less confidence in answering implicit questions and that reviewing the text has a significant effect on response correctness for implicit questions. The form of text layout did not show a significant effect, however. Our results have implications for lecturers who set readings and questions for comprehension and others who use reading comprehension as part of their ‘hidden curriculum’. Further research in this area is required to determine more precisely the effects of language background. 相似文献

Multidimensional models of giftedness specify individual and environmental moderators or catalysts that help transform potential into achievement. However, these models do not state whether the importance of the ‘individual boxes’ and the ‘environmental boxes’ changes during this process. The present study examines whether, during the early stages of talent development, the ‘environmental boxes’ play a more important role than the ‘individual boxes.’ To answer this question, we analyzed individual moderators and environmental moderators of achievement for fourth-grade primary-school students (N?=?976). A cluster analysis that included intelligence, achievement, and two individual moderators (motivation and learning behavior) revealed three groups of students, two of which are of particular interest, as they both displayed high intelligence and achievement but differed in their motivation and learning behavior. Questionnaire data on family environment (filled out by parents, N?=?682) and school environment (filled out by teachers, N?=?47) supported the assumption that among young students an inauspicious set of individual moderators, in this case maladaptive motivation and learning behavior, can be compensated by a sufficiently propitious set of environmental moderators, in this case parents’ and teachers’ learning support, cultural capital within the family, and teachers’ commitment to support their students’ learning. 相似文献

Previous correlational and quasi‐experimental studies of arts integration—the pedagogical practice of “teaching through the arts”—suggest its value for enhancing cognitive, academic, and social skills. This study reports the results of a small, preliminary classroom‐based experiment that tested effects of arts integration on long‐term retention of content. We designed matched arts‐integrated (AI) and conventional science units in astronomy and ecology. Four randomized groups of 5th graders in one school completed one unit in the treatment (AI) condition and the other in the control (conventional) condition. To control for teacher effects, four teachers taught the same subject to different groups in each condition. We administered curriculum‐based assessments before, immediately after, and 2 months after each unit to measure initial learning and retention. Results showed no differences in initial learning, but significantly better retention in the AI condition. Increases in retention were greatest for students at the lowest levels of reading achievement. 相似文献

AbstractThe aim of this study was to assess the impact of the choice of threshold on physical activity patterns measured in adolescents under free living conditions (FLC) using a uniaxial accelerometer. The study comprised 2043 adolescents (12.5–17.5 years) participating in the HELENA Study. Participants wore a uniaxial accelerometer for 7 days. The PA patterns were assessed using thresholds determined from six different studies. For each of the thresholds used, the number of adolescents fulfilling the recommendation of 60 min of moderate to vigorous PA (MVPA) per day was also calculated. A significant difference was found between thresholds regardless of the activity level: differences of 38%, 207%, 136%, and 2780% for sedentary, light, moderate, and vigorous intensity PA, respectively (P < 0.001). Time of MVPA varied between methods from 25.3 to 55.2 min · day–1. The number of adolescents fulfilling the recommendation varied from 5.9% to 37% according to the thresholds used. The kappa coefficient for concordance in the assessment of the number of adolescents achieving the PA recommendations was generally low. The definition of the threshold for PA intensity may considerably affect the PA patterns in FLC when assessed using a uniaxial accelerometer and the number of participants fulfilling the recommendations. 相似文献

Abstract The problem involved the determination of the base concentration of ATP in muscle tissue of white rats. These animals had been forced to exercise (train) by swimming. The method used to analyze for ATP involved bioluminescene and spectrophotometry. The luciferin-luciferase system served as the bioluminescence source. The Fisher's t test for significance was computed from the data collected. The peak height, obtained from the reaction of ATP and the luciferase system which was recorded, indicated the amount of ATP present. The results obtained were not significant at the .05 level. Based on the findings of this study it was concluded that there was not a significant change in the base concentration of ATP in the experimental rats as compared to the control rats, and that there was a definite trend of an increased basal concentration of ATP in the exercised animals. 相似文献

Changes to federal guidelines for the identification of children with disabilities have supported the use of multi‐tiered models of service delivery. This study investigated the impact of measurement methodology as used across numerous tiers in determining special education eligibility. Four studies were completed using a sample of inner‐city children (N = 150) who were administered a reading screener twice and a reading measure adapted from the state high‐stakes reading test. A sub‐sample of children identified as At‐Risk were administered a comprehensive reading assessment and compared with a randomly selected control group, who were also administered a comprehensive reading assessment (n = 14). A model was developed to estimate the likelihood of special education eligibility based on both theoretical and empirical measurement parameters. Depending on the measurement assumptions of the multi‐tiered model, special education eligibility outcomes varied from a low of 0.2% to as high as 11%, depending on the type of measure used, decision‐making criteria used at each tier, and the number of tiers in the model. This study highlights the importance of measurement specification, explicit decision‐making criteria, and empirical investigation to fully understand outcomes associated with the implementation of multi‐tiered models. Implications for special education eligibility policy and practical implications for implementing comprehensive measurement practice in multi‐tiered systems at the school level are discussed. © 2012 Wiley Periodicals, Inc. 相似文献
