Who's Afraid of the Bad Little Fowl?     

Celia Keenan 《Children‘s Literature in Education》2004,35(3):257-270

The question this article addresses is: Is “Artemis” art? That is, how successful is Eoin Colfer's attempt to combine disparate forms, such as fairy stories, science fiction stories and thrillers in the three “Artemis Fowl” novels? Basic elements of story, such as narrative stance, characterisation and plot, as well as some particularly contemporary issues relating to political correctness, are examined in the search for an answer to that question.  相似文献   

The Performance of Multilevel Models When Outcome Data Are Incomplete     

Wanchen Chang  Keenan A. Pituch 《Journal of Experimental Education》2019,87(1):1-16

When data for multiple outcomes are collected in a multilevel design, researchers can select a univariate or multivariate analysis to examine group-mean differences. When correlated outcomes are incomplete, a multivariate multilevel model (MVMM) may provide greater power than univariate multilevel models (MLMs). For a two-group multilevel design with two correlated outcomes, a simulation study was conducted to compare the performance of MVMM to MLMs. The results showed that MVMM and MLM performed similarly when data were complete or missing completely at random. However, when outcome data were missing at random, MVMM continued to provide unbiased estimates, whereas MLM produced grossly biased estimates and severely inflated Type I error rates. As such, this study provides further support for using MVMM rather than univariate analyses, particularly when outcome data are incomplete.  相似文献

Towards a Better Understanding of the Dynamic Role of the Distance Language Learner: Learner perceptions of personality,motivation, roles,and approaches     

Stella Hurd 《Distance Education》2006,27(3):303-329

This study investigated the experience of learners enrolled on an Open University (UK) French course, and included personality factors, motivation, and tutor and student roles. The data gathered via multiple elicitation methods gave useful insights into issues of special relevance to distance language education, in particular the lack of fit between an inherently social discipline such as language learning and the distance context, whose main characterizing feature is remoteness from others. Motivation was seen to play a crucial role in success, along with tutor feedback, and personal responsibility for learning. Increased confidence and self‐regulation were beneficial outcomes of the process of learning at a distance, and numerous suggestions for learning approaches based on personal experience were offered for language learners new to distance learning. The study concluded that the task for distance practitioners is to build on the insights shown by learners themselves, in order to target support where it is most needed.  相似文献   

Evaluating the effects of analogy enriched text on the learning of science: The importance of learning indexes     

Stella Vosniadou  Irini Skopeliti 《科学教学研究杂志》2019,56(6):732-764

Research has shown that differences in the prior knowledge of the participants and in the learning indexes adopted can explain why some studies show positive learning effects of analogy enriched text while others do not. In the present studies, these two factors were combined into one through the construction of a learning index that measured incremental positive changes in the participants' prior knowledge after reading an analogy enriched or no analogy text. A second learning index was also used to evaluate whether the participants created well-formed conceptual models after reading the science text. These learning indexes were used in two studies in which the effects of analogy enriched versus no analogy text were compared on the learning of the scientific explanations of the day/night cycle and of the seasons. The participants were 3rd and 5th graders in the first study and 6th graders and college students in the other. Although only few of the participants learned the correct scientific explanation, those who read the analogy enriched text produced more incremental positive changes in their pretest explanations at posttest and delayed test and created more well-formed conceptual models close to the scientific one than those who read the no analogy text. They also recalled more information and created fewer invalid inferences in their recalls. The results indicate that analogies can be used without reservation to facilitate the learning of science and have broader implications about how to evaluate the learning of science in general.  相似文献   

What can persuasion research tell us about conceptual change that we did not already know?     

Stella   《International Journal of Educational Research》2001,35(7-8)

The chapters included in this special issue are innovative in their attempt to bring together research on persuasion with research on conceptual change. Although persuasion and conceptual change are not similar in all respects, they both involve belief change. They also both require that we better understand the variables that make a text persuasive and thus influence the reader to change his/her beliefs. These chapters are instrumental in bringing about three important characteristics of persuasive text that can also be useful in inviting conceptual change. These characteristics are the comprehensibility, clarity and credibility of the text; the importance of explicitly addressing the readers’ prior beliefs; and affective and motivational factors.  相似文献   

Using Theory of Mind to Promote Conceptual Change in Science     

Natassa Kyriakopoulou  Stella Vosniadou 《Science & Education》2014,23(7):1447-1462

We argue that learning science requires children to move from perceptually based representations to more abstract conceptual representations and to understand that appearance may sometimes deceive us and that the same phenomenon in the world can have more than one representation when seen from different perspectives. We also argue that the beginnings of such an epistemological perspective can be found in young children’s ability to think about the difference between their beliefs and the beliefs of others in the social domain, i.e., their Theory of Mind. We present the results of two empirical studies that show significant correlations between children’s growing Theory of Mind, developing epistemological thinking, and science learning, and suggest that Theory of Mind tasks can be used to promote conceptual change in science.  相似文献

Classification Consistency and Accuracy for Mixed-Format Tests     

Stella Y. Kim  Won-Chan Lee 《教育实用测度》2019,32(2):97-115

This study explores classification consistency and accuracy for mixed-format tests using real and simulated data. In particular, the current study compares six methods of estimating classification consistency and accuracy for seven mixed-format tests. The relative performance of the estimation methods is evaluated using simulated data. Study results from real data analysis showed that the procedures exhibited similar patterns across various exams, but some tended to produce lower estimates of classification consistency and accuracy than others. As data became more multidimensional, unidimensional and multidimensional item response theory (IRT) methods tended to produce different results, with the unidimensional approach yielding lower estimates than the multidimensional approach. Results from simulated data analysis demonstrated smaller estimation error for the multidimensional IRT methods than for the unidimensional IRT method. The unidimensional approach yielded larger error as tests became more multidimensional, whereas a reverse relationship was observed for the multidimensional IRT approach. Among the non-IRT approaches, the normal approximation and Livingston-Lewis methods performed well, whereas the compound multinomial method tended to produce relatively larger error.  相似文献
