Although many theories mention distractions by conflicting alternatives as a problem for self-regulation, motivational conflicts are rarely considered when explaining impairments in learning. In two studies, we investigate the assumption of motivational interference theory that students show different amounts of impairments in learning depending on the presence and motivational strength of conflicting alternatives. In Study 1 (N?=?221), the subjective value attributed to a respective alternative in a study–leisure conflict scenario partially accounted for differences in self-regulated learning while controlling for interindividual differences. Study 2 (N?=?112) demonstrated that this pattern applies to both when the respective alternatives refer to ‘liking to’ (want conflicts) and ‘having to’ (should conflicts) do something. Moreover, it is demonstrated that impairments due to motivational conflict are higher than impairments inherent in the studying activity itself (baseline). The results emphasise the importance of concurring action alternatives for explaining difficulties in self-regulated learning.  相似文献

The present study examined the facilitating function of animations for spatial perspective taking. The task demanded to estimate directions to memorized objects in a spatial scene from an imagined position and orientation within the scene. Static pictures which required imagined reorientation of the self were compared to animations showing the reorientation externally. Individual differences in perspective taking ability were considered. Results showed a large effect in favor of animations for reaction times. An aptitude–treatment-interaction was found for accuracy: The relation between perspective taking ability and accuracy in direction estimation was moderated by type of presentation (static pictures vs. animation). Perspective taking ability played a much stronger role in direction estimation accuracy with static pictures than with animations. It is concluded that focused animations can facilitate perspective taking and thereby compensate for low spatial perspective taking ability.  相似文献

This study investigates the relationships between professional knowledge, self-concept, and interest of pre-service physics teachers. In order to support student learning and interest development alike, teachers need a profound professional knowledge and respective motivational orientations. Developing both professional knowledge and motivational orientations in teachers is therefore a key challenge of teacher education. Prior research has focused on the development of content knowledge (CK) and pedagogical content knowledge (PCK) within teacher education, but the role of motivational orientations such as self-concept and interest have mostly been neglected areas of study. As individuals develop domain-specific motivational orientations, they compare their achievement in an external frame to the achievement of their peers, and they compare their achievements in an internal frame across domains. The effects of these psychological processes on domain-specific motivational orientations are described by the generalized internal/external frame of reference model (GI/E model). We assessed the professional knowledge (CK and PCK) and motivational orientations (self-concept and interest) of N = 200 pre-service physics teachers from 12 teacher education institutes in Germany. To investigate the predictions of the GI/E model, we utilized structural equation modeling. In line with the GI/E model, the analysis revealed that pre-service teachers use social comparisons. Pre-service teachers with a higher CK/PCK also showed a higher CK/PCK self-concept. We also identified instances of internal comparisons as we found that a high level of CK corresponds with a lower PCK self-concept. While we could not identify the same effects from professional knowledge on interest, self-concept mediated the effects from professional knowledge on interest. The results suggest that interdependencies between professional knowledge and motivational orientation should be given more consideration in teacher education research and should also be addressed more explicitly in teacher education.  相似文献

As the concept of distributed leadership and its concomitant organizational structures become more prevalent in schools, studying how teacher capacity can be enhanced and can be used as a catalyst for reform is important. This article documents the nature of how the implementation of a research-validated reform influenced what teachers thought about their own teaching, student achievement, and expectations. A case study approach documented the experiences of elementary school teachers in a high poverty, historically low-performing elementary school as they implemented a researched-validated instructional reform targeting the most at-risk students in the school. The teachers experienced significant professional growth that encompassed self-doubt, resistance, acceptance, and finally advocacy. Implications for the practices that define educational leadership and school improvement are discussed in light of how successful reform can improve teacher capacity.  相似文献

We inductively develop a model of the commercialization process for new products or services user entrepreneurs undertake when entering an industry while drawing on proprietary technology developed in another industry. Extending the growing field of user entrepreneurship, we identify a two-phase approach to industry entry by user entrepreneurs who start “under the radar” of incumbent firms, gain experience, attract a first potential customer base, and then, in a second phase, engage in commercialization. During this process, a community of fellow users is of major importance for the entrepreneur, serving as a knowledge pool for skills development and experimentation with different commercialization paths. We study a nascent group of firms founded by users of video games who became entrepreneurs on entering the animation industry by producing Machinima, a new film genre characterized by shooting film in video games. We explain how user entrepreneurs gain access to complementary assets (video games) for their new use (shooting film), how they deal with intellectual property issues when using other firms’ assets, and how user entrepreneurs combine domain knowledge about film production with their experience in video games and the art of Machinima. Our propositions hold implications for management and policy.  相似文献

Researchers have not yet reached agreement about the validity of several competing explanations that seek to explain ethnic differences in juvenile violent offending. Ethnicity cannot solely explain why boys with an ethnic minority background commit more (violent) crimes. By assessing the intersectionality of structural, cultural and individual considerations, both the independent effects as well as the interplay between different factors can be examined. This study shows that aforementioned factors cumulatively play a role in severe violent offending, with parental connectedness and child abuse having the strongest associations. However, since most variables interact and ethnicity is associated with those specific factors, a conclusion to be drawn is that ethnicity may be relevant as an additional variable predicting severe violent offending although indirectly.  相似文献

A highly skilled maintainer is the most important organisational asset pivotal for achieving quality software, strategic for improving maintenance and development processes, essential for remaining competitive and critical for business survival. This requires that universities properly prepare students to enter the maintenance workforce and that maintenance organisations actively build and maintain their human knowledge and skill base. In this paper, we present Corrective Maintenance Maturity Model (CM 3): Maintainers' Education and Training – a maturity model for educating and training maintenance engineers within corrective maintenance. This model is presently being developed at ABB by the Software Maintenance Laboratory (SML). Our goal is to provide guidance to ABB and industrial organisations worldwide in the process of building or improving their most important asset – people. Each process element presented in this paper is matched against its corresponding process element at ABB. Hence, this paper may also be regarded as a report on the state of the current practice of educating and training maintainers at ABB.  相似文献

The ability to build arguments is a crucial skill and a central educational goal in all school subjects including science as it enables students to formulate reasoned opinions and thus to cope with the increasing complexity of knowledge. In the present cross-sectional study, we examined the domain-specificity of argumentative writing in science by comparing it with a rather general type of argumentation as promoted in first-language education and with formal reasoning to gain insight into different forms of argumentation on theoretical and empirical levels. Using a paper-and-pencil test, we analyzed written argumentations and the reasoning abilities of 3,274 Grade-10 students in German secondary schools. Correlation and multiple regression analyses as well as a qualitative analysis of students' answers to a subset of tasks in the domains of science and first-language education were conducted. Results showed moderate relations between argumentation in science, argumentation in first-language education, and reasoning. Half of the variance in argumentation in science was explained by individual differences in argumentation in first-language education and reasoning. Furthermore, the examination of written arguments revealed differences, for example, in students' weighing of pros and cons. We assume that the familiarity of the underlying scientific information may play an essential role in the argumentation process and posit that it needs to be investigated in more detail. Overall, the study indicates that investigating the argumentational abilities of learners in first-language education and reasoning abilities can help to shed light on the domain-specificity of argumentation in science.  相似文献

According to the Simple View of Reading, reading ability can be divided into decoding and language comprehension. In the present study, decoding and comprehension's contribution to reading ability was studied both in children with reading difficulties and in children with typical reading ability. Decoding and comprehension was further divided into sub-components, and the contribution from non-verbal ability and general processing speed was also studied. The results demonstrated that decoding made the largest contribution to reading ability for children with reading difficulties, while language comprehension contributed the most for children with typical reading ability. The contribution of non-verbal ability was not significant, and general processing speed only made a significant contribution to decoding for typical children. The two factors in the Simple View of Reading, decoding and comprehension, together explained less of the variance in reading ability for children with reading difficulties than for children with typical reading ability.  相似文献
