Adaptive educational games provide new opportunities to train early numerical skills. However, empirical evidence for the effectiveness of adaptive educational games is scarce. This study investigated the effectiveness of an adaptive game compared to a nonadaptive game in terms of cognitive, noncognitive and efficiency outcomes. In total, 84 children were randomly assigned to a condition in which children trained early numerical skills with an adaptive version of the Number Sense Game (NSG), or to a condition in which they trained with a nonadaptive version. Early numeracy was evaluated before the training, immediately after the training and 3 weeks after the training. Math anxiety (MA) was assessed before and 3 weeks after the training. The time children practiced with the NSG was used to assess efficiency. Results revealed that children in both conditions improved on early numerical ability, with sustained effects 3 weeks after the training. In both conditions, children’s MA scores were lower after the training. Children in the adaptive condition learned more efficiently compared to the nonadaptive condition, and the interaction between prior knowledge and condition has shown that children with low prior knowledge benefited more from a nonadaptive training while children with high prior knowledge benefited more from an adaptive training in terms of learning efficiency. These results confirm that adaptive educational games can offer solace in terms of the need for differentiation. 相似文献

Prognostic factors influence the modality and course of therapy in breast cancer. These include both histopathological and
biochemical variables. This study was aimed to find out if any correlation exists between the biochemical tumor marker-serum
CA 15.3, and the lymph node staging of Nottingham’s Prognostic Index (NPI). It was observed that serum CA 15.3 showed a statistically
significant correlation with lymph node staging of NPI. Therefore it is concluded that CA 15.3 can be utilized as a useful
prognostic marker, particularly in cases where histopathological variables such as tumor size and grade have been altered
by pre-operative chemotherapy. 相似文献

OBJECTIVE: The aim of this article is to review what is currently understood about intergenerational transmission of child sexual abuse (CSA). METHOD: CSA transmission is discussed first from the point of view of men CSA survivors who become sexually abusive, and then from the perspective of mothers who survived CSA whose children have been sexually abused. Mechanisms that may help us understand how CSA is transmitted from one generation to another are described. More specifically, focus is given to those mechanisms that might differentiate CSA survivors who break the cycle of abuse from those who perpetuate it. RESULTS: In light of the research reviewed, it seems that the transmission of CSA is far from inevitable, since one-third of sexually abusive men and half of sexually abused children's mothers mentioned having been sexually abused in their childhood. Because of the retrospective method used in many studies, causal links could not be established. However, some mechanisms have been proposed in order to better understand the phenomenon of CSA. Severity of abuse, attachment relationships with parental figures, as well as dissociative symptoms that follow the abuse were identified. Dissociative symptomatology appeared to be a determining factor in understanding the cycle of CSA. CONCLUSIONS: More studies on CSA transmission are needed to understand the mechanisms that are involved in that cycle, as well as to develop effective strategies to treat and prevent CSA. 相似文献

ABSTRACT Exploring new sources on the Great War a hundred years after it ended is a unique and exciting experience for any First World War historian. The very nature of the documents that we are dealing with in the present case makes it even more thrilling: hundreds of investigation and prosecution files documenting the invasion and occupation of Belgium, produced by both military and civil jurisdictions in an effort to prosecute war criminals. These fascinating records – repatriated to Belgium from Moscow in 2002 – offer new material on issues such as the German atrocities and everyday life under the occupation, but they also provide highly valuable insights into the history of international criminal law. This exploratory article will trace the unexpected trajectory of these archives, contextualise their creation and highlight some of the treasures they contain. In doing so, this article will attempt to discuss the thorny issue of archive repatriation and the questions this raises from an archival and historical perspective. It also seeks to show that the establishment of an International Criminal Court, despite the fact that it is now being called into question more than ever before, rests on solid and far-reaching historical foundations. 相似文献

In this study, we examined the effects of three recovery intensities on time spent at a high percentage of maximal oxygen uptake (t90[Vdot]O(2max)) during a short intermittent session. Eight endurance-trained male adolescents (16 +/- 1 years) performed four field tests until exhaustion: a graded test to determine maximal oxygen uptake ([Vdot]O(2max); 57.4 +/- 6.1 ml x min(-1) . kg(-1)) and maximal aerobic velocity (17.9 +/- 0.4 km x h(-1)), and three intermittent exercises consisting of repeat 30-s runs at 105% of maximal aerobic velocity alternating with 30 s active recovery at 50% (IE(50)), 67% (IE(67)), and 84% (IE(84)) of maximal aerobic velocity. In absolute values, mean t90[Vdot]O(2max) was not significantly different between IE(50) and IE(67), but both values were significantly longer compared with IE(84). When expressed in relative values (as a percentage of time to exhaustion), mean t90[Vdot]O(2max) was significantly higher during IE(67) than during IE(50). Our results show that both 50% and 67% of maximal aerobic velocity of active recovery induced extensive solicitation of the cardiorespiratory system. Our results suggest that the choice of recovery intensity depends on the exercise objective. 相似文献

The present experiments were aimed at testing Karmiloff-Smith's (1992) assumption that representational flexibility in drawing behavior requires the relaxation of a sequential constraint. A total of two hundred and forty 5- to 9-year-old children produced cross-category drawings (e.g., a house with wings) in 4 conditions. The results indicated that procedural rigidity declined as representational change improved. The decline in procedural rigidity occurred before representational change attained its highest level. This decline was related to a greater ability to manage early interruptions of the procedures, not to a greater ability to modify the usual feature sequencing. It was concluded that rigidity in routine development could act as a sequential constraint on interrepresentational change. 相似文献

Serum β2-microglubin (β2-m) levels were measured in oral carcinoma patients and compared with normal healthy controls. It was observed that there
was a significant rise in serum β2-microglobulin in oral carcinoma patients. Progressively higher values were obtained as the cancer advanced clinically. Therefore
the estimation of serum β2-microglobulin may be useful as one of a battery of tests in the assessment of oral carcinoma patients. 相似文献

The aim of this study was to show how general models of text production can account for argumentative text planning. It focuses in particular on retrieval process in 11- to 18-year-old children. Various experimental situations were designed to promote different ways of retrieving ideas from long-term memory. Essays written by students were analyzed quantitatively (number of thematic units) and qualitatively (taking addressee into account). It seems that the procedures used here had an impact on the quantitative aspect of the essays written, but had little effect on their quality, no matter how old the children were. Thus, retrieval does not appear to be the most critical process in the production of this type of text. 相似文献
