This study investigated whether German learners of English as a foreign language (EFL) acquire additional recoding strategies that they do not need for recoding in the consistent German orthography. Based on the psycholinguistic grain size theory (Ziegler & Goswami, 2005) we expected students with little experience in EFL to use the same small-grain recoding strategy as in German, while more advanced students were expected to switch flexibly between small and large grain size recoding strategies when reading English nonwords. German students in Grades 5, 7, and 9, as well as university students were presented with an experimental nonword reading paradigm introduced by Goswami, Ziegler, Dalton, and Schneider (2003) which assesses the effects of language (nonwords derived from German vs. English), orthographic neighborhood, item length and presentation format (blocked vs. mixed) on reading latencies and accuracies. The data were analyzed using hierarchical linear models. The youngest age group did not use larger units to read English nonwords, but mostly applied simple grapheme-phoneme translation, as they would in their first language. University students were able to switch flexibly between large- and small size recoding strategies. 相似文献

Research was undertaken to evaluate whether and to what extent the health‐related domains, including sexuality education, specified by the Development of Health Awareness in Adolescent Project Science Committee overlapped with the goals and objectives of the 2002/03 elementary school curricula (grades one to eight; ages 7–14 years) in Turkey. For this aim, the goals and objectives of the courses in the curricula that include health‐related and sexuality‐related subjects were compared by the seven domains with a total of 230 subcategories. The analysis demonstrated that 147 of the 230 subcategories matched the goals and objectives of the curricula with the highest frequencies in the domains of physical development, protection from detrimental‐external factors and healthy living habits. However, the domain of healthy beginning to life was found to have the lowest frequency. Moreover, subcategories such as pregnancy–birth, unintended pregnancy, sexual identity, changes in adolescence, sexual violence and abuse, birth control and sexual discrimination were not covered at all. These results are discussed in relation to the missing points that might have implications for policy and practice in health and sexuality education in Turkey. 相似文献

The present paper reports on an empirical study which investigated learning with text and animations in the science classroom. In a 2?×?2 design the presence of multimedia learning material instruction (text only vs. text + animations) as well as the modality of the explanatory text (spoken vs. written) were tested. Prior to learning, students’ motivation to learn was assessed as a continuous factor. Recall and transfer were assessed immediately after learning. The results show better recall of information for learners with multimedia materials, providing the animations were accompanied by spoken text. However, in contrast to the positive effects of domain-specific motivation this multimedia effect was not evident for transfer. The effects of multimedia design were independent of motivation. Implications for future studies are discussed. 相似文献

Research shows that students, and sometimes teachers, have trouble with fractions, especially conceiving of fractions as numbers that extend the whole number system. This paper explores how fractions are addressed in undergraduate mathematics courses for prospective elementary teachers (PSTs). In particular, we explore how, and whether, the instructors of these courses address fractions as an extension of the whole number system and fractions as numbers in their classrooms. Using a framework consisting of four approaches to the development of fractions found in history, we analyze fraction lessons videotaped in six mathematics classes for PSTs. Historically, the first two approaches—part–whole and measurement—focus on fractions as parts of wholes rather than numbers, and the last two approaches—division and set theory—formalize fractions as numbers. Our results show that the instructors only implicitly addressed fraction-as-number and the extension of fractions from whole numbers, although most of them mentioned or emphasized these aspects of fractions during interviews. 相似文献

In this study, we investigate the logistic regression (LR), Mantel-Haenszel (MH), and Breslow-Day (BD) procedures for the simultaneous detection of both uniform and nonuniform differential item functioning (DIF). A simulation study was used to assess and compare the Type I error rate and power of a combined decision rule (CDR), which assesses DIF using a combination of the decisions made with BD and MH to those of LR. The results revealed that while the Type I error rate of CDR was consistently below the nominal alpha level, the Type I error rate of LR was high for the conditions having unequal ability distributions. In addition, the power of CDR was consistently higher than that of LR across all forms of DIF. 相似文献

Implementation Intentions for Improving Self-Regulation in Multimedia Learning: Why Don’t They Work?
AbstractLearners face several self-regulatory challenges during multimedia learning: choosing adequate cognitive strategies (cognitive self-regulation), relying on their own learning abilities (motivational self-regulation), and investing sufficient effort (behavioral self-regulation). Implementation intentions (plans that help transform intentions into action) can support self-regulation. We expected that cognitive, motivational, or behavioral implementation intentions improved learning, compared to a control group. In a first experiment, we found weak evidence that cognitive and behavioral implementation intentions improved learning, whereas motivational implementation intentions reduced learning. However, replication failed in two follow-up experiments. Our findings contradict previous research and suggest that implementation intentions are not suitable to support multimedia learning. Future research should focus on possible boundary conditions that could account for the unexpected and unstable findings. 相似文献

A lot of research has focused on the beneficial effects of using multimedia, that is, text and pictures, for learning. Theories
of multimedia learning are based on Baddeley’s working memory model (Baddeley 1999). Despite this theoretical foundation, there is only little research that aims at empirically testing whether and more importantly
how working memory contributes to learning from text and pictures; however, a more thorough understanding of how working memory
limitations affect learning may help instructional designers to optimize multimedia instruction. Therefore, the goal of this
review is to stimulate such empirical research by (1) providing an overview of the methodologies that can be applied to gain
insights in working memory involvement during multimedia learning, (2) reviewing studies that have used these methodologies
in multimedia research already, and (3) discussing methodological and theoretical challenges of such an approach as well as
the usefulness of working memory to explain learning with multimedia. 相似文献

Examining the discourse on the limit concept in a beginning-level calculus classroom 总被引：1，自引：1，他引：0

Existing research on limits documents many difficulties students encounter when learning about the concept. There is also some research on teaching of limits but it is not yet as extensive as the research on student learning about limits. This study explores the discourse on limits in a beginning-level undergraduate calculus classroom by focusing on one instructor’s and his students’ discourses through a communicational approach to cognition. The findings indicate that some of the limit-related contexts in which students struggled coincided with those in which the instructor shifted his elements of discourse on limits. The instructor did not attend to the shifts in his discourse, making them implicit for the students. The study highlights that the discrepancies among participants’ discourses signal communicational breakages and suggests that future studies should examine whether teachers’ explicit attention to the elements of their discourse can enhance communication in the classrooms. 相似文献
