This study examined ways in which high school students used mobile devices in physics classrooms and after school, and the impact of in‐class and after‐school mobile technology use on their physics learning performance and interest. We collected data from 803 high school freshmen in China after they had used mobile devices for over five months. A fixed‐effects model was employed to control the undetected variances. Results indicated that the students frequently used their mobile devices for physics learning in class and after school. Students also perceived the mobile devices as very useful for their physics learning, and their perception of usefulness was positively correlated with their frequency of use. Both the in‐class and after‐school duration and frequency of mobile technology use positively influenced students' physics learning achievement and interest. However, we also found that mobile technology was mainly used to augment rather than to transform instructional practices in physics classrooms. The paper concludes with a discussion of implications and limitations of these results for research and practice.  相似文献

Teacher–student interactions in 17 inclusive classrooms were examined using a mixed‐methods approach that involved quantitative analysis of interactions recorded during classroom observations and follow‐up interviews with seven general educators. Observational findings suggest that classrooms were organised along traditional lines with the vast majority of interactions provided by general educators to the whole class, followed by brief intervals of 1 : 1 interactions directed towards individual students, most frequently children with disabilities. Interview findings suggest that teachers were aware of the greater individual attention devoted to students with disabilities and described a number of ways that they adapt their instruction that are consistent with the research on effective teaching. In addition, participants struggled with the dilemma of balancing their attention between students whom they perceived as needing it most and ensuring that the class as a whole made adequate progress. The analysis of both observational and interview data indicates that paraprofessionals were responsible for a large portion of instruction and curricular decision making for children with severe disabilities in these classrooms.  相似文献

We investigated the longitudinal relations between cognitive skills, specifically language-related skills, and word-problem solving in 340 children (6.10–9.02 years). We used structural equation modeling to examine whether word-problem solving, computation skill, working memory, nonverbal reasoning, oral language, and word reading fluency measured at second grade were associated with performance on measures of word-problem solving in fourth grade. Results indicated that prior word-problem solving, computation skill, nonverbal reasoning, and oral language were significantly associated with children’s later word-problem solving. Multi-group modeling suggested that these relations were not significantly different for boys versus girls. Implications of these findings are discussed.  相似文献

With a Meta-Analytic Structural Equation Modeling approach, we investigated the role of whole-number knowledge on fraction performance, accounting for domain-general skills, age, and mathematics-difficulty status. We conducted analyses based on 6,096 students from 39 independent samples within 29 studies. Findings suggested conceptual whole-number knowledge emerged as a significant and stable predictor of conceptual and procedural fraction knowledge. More importantly, students experiencing mathematics difficulty demonstrated a distinct pattern of performance compared to typically-achieving students, including: conceptual whole-number knowledge had lesser impacts on conceptual fraction knowledge; procedural whole-number knowledge had greater impacts on procedural fraction knowledge; and working memory and fluid intelligence made fewer contributions to fraction knowledge.  相似文献

Serious educational gameplay continues to gain traction in K-12 educational settings, as access to novel technologies increases. Increased access to computers and other devices has shifted the landscape of the classroom, increasing students' screen-time, as technology infused lessons replace other learning experiences. Amid this context, our research team created a serious educational game (SEG) designed for elementary science learners. Previous studies have linked serious gameplay to learning gains and changes in attitudes, yet the rigor of the studies often underwhelms, as the studies lack an adequate sample size, detailed student data, or quality comparison groups. These limitations are compounded in the study of science learning in elementary schools, due to structural difficulties and student variability that impede the implementation of this type of experimentation. This research attends to this knowledge gap, as our team conducted two quasi-experimental studies to explore the learning gains associated with Virtual Vet, a SEG designed to address the fundamental science concepts associated with the human body systems and the subsequent effect of diabetes and obesity related illnesses on the given body systems. In Study 1, students (n = 232) were randomly assigned to play Virtual Vet or participate in guided inquiry lessons that addressed the same objectives. Our study found that students in the game condition outperformed the non-game condition. Based on this finding, we designed Study 2 to compare learning outcomes associated with two conditions: students play only Virtual Vet or students play Virtual Vet and they participate in the guided inquiry activities, which doubled the instructional time for this group. Students (n = 166) were assigned to one of the conditions and we found no significant increase in learning gains for the students who participated in both activities. These results indicate that well-designed SEGs powerfully facilitate and support science learning in elementary settings.  相似文献

This paper outlines a research project conducted at Leeds University School of Medicine with Assessment & Learning in Practice Settings Centre for Excellence in Teaching and Learning, collaboration between the Universities of Leeds, Huddersfield, Bradford, Leeds Metropolitan University and the University of York St John. The research conducted is a proof of concept, examining the impact of delivering competency based assessment via personal digital assistants (PDAs) amongst a group of final year undergraduate medical students. This evaluation reports the student experience of mobile technology for assessment with positive effects; concluding that overall the students found completing assessments using a PDA straight forward and that the structured format of the assessment resulted in an increased, improved level of feedback, allowing students to improve their skills during the placement. A relationship between using the PDA for learning and setting goals for achievement was clearly demonstrated.  相似文献

Speech pathology students enrolled in a lecture‐based gross human anatomy program completed two out of nine topics in self‐directed mode. Student performance in quizzes was compared for the two modes, and the students completed questionnaires on their perceptions of the self‐directed mode of delivery. Students performed as well in the first self‐directed topic as they did in lecture‐based material, but performance declined significantly on the second self‐directed topic. Correlations showed that students who performed well in lecture‐based topics also performed well on self‐directed topics. The major issues that arose in the student questionnaires were primarily related to the amount of content in the topics and the length of time required for completion. We conclude that there is a strong need for appropriate design of distance education materials to reflect student perceptions of length, content, and time investment, and more importantly that there is a need to ensure extensive communication and support of students studying in distance education/self‐directed modes for the first time.

Mobile technology has been increasingly adopted in science education. We generally assume that more innovative use of mobile technology leads to a greater learning outcome. Yet, there is a lack of empirical research to support this assumption. To fill in the gap, we drew upon data from 803 high school students who had used mobile devices for five months in physics classrooms. Using the SAMR model (ie, Substitution, Augmentation, Modification, and Redefinition), we distinguished their uses into two levels: Substitution (replacing traditional instructional approach with mobile technology without functional improvement), and augmentation (enhancing instruction with affordances provided by mobile technology). Using Hierarchical Linear Modeling analysis, we found that the augmentation level of use was positively correlated with the physics learning outcome, but the substitution level of use was not. We further identified four sub-types of uses within the augmentation level. We found that after-school remediating activities and student–teacher displaying activities were positively correlated with student physics achievement, but teacher-assigned activities had no significant correlation and learning aid activities had a negative correlation with the learning outcome. This study provided empirical evidence to support the assumption that a higher level of mobile technology use may be related to a greater learning outcome and that the impact of mobile technology may be determined by multiple factors such as who initiates the use and whether the use enhances or distracts students' knowledge construction.  相似文献

This paper examines students' perceptions of their classroom environment and the possible effect of these perceptions on math and reading achievement. Additionally, the paper investigates the significance of gender and grade level on students' perceptions of the classroom environment.

Participants were elementary school students in a large urban school district in the western part of the US. Data collected were based on test scores on the Washington Assessment of Student Learning (WASL) and scores on the My Classroom Inventory (MCI) to measure perceptions. Correlation analyses and multivariate analysis of variance (MANOVA) procedures were used to analyse the data. The results indicated that the perceptions of the general classroom environment were significantly related to math and reading achievement, although this was not the case for the individual dimensions of the classroom environment. Gender had no statistically significant association with the students' perceptions of the classroom environment, whereas the grade level had a statistically significant relationship with the perceptions.  相似文献

Despite the theorized centrality of pedagogical content knowledge (PCK) for teaching, we have little evidence of the relationship between PCK and students' learning and know relatively little about how to help teachers to develop PCK. This study is a preliminary attempt to address these gaps in our knowledge of PCK through exploration of two German physics teachers' classroom instruction in consecutive lessons on optics. We show how video analysis can be used to gather evidence for one aspect of teachers' PCK: their use of content knowledge in interactions with students. We identify three potentially important characteristics of this aspect of PCK: flexibility, richness, and learner‐centeredness. By contrasting teachers with high and low gains in student knowledge and interest, we explore potential mechanisms by which this aspect of PCK might affect student outcomes. Because German teacher preparation programs emphasize content more than pedagogical knowledge, these cases contribute to our understanding of the support that teachers with strong content knowledge may need in translating this knowledge into a form useful for teaching.Fachdidaktisches Wissen ist aus theoretischer Sicht besonders zentral für das Unterrichten. Aus empirischer Sicht gibt es bislang allerdings noch wenig Evidenz für den Einsatz fachdidaktischen Wissens während des Unterrichtens und seine Bedeutung für das Lernen von Schülerinnen und Schülern. Außerdem wissen wir wenig darüber, wie Lehrpersonen über die Zeit fachdidaktisches Wissen entwickeln. Diese Studie ist ein Versuch, diese Wissenslücken zum fachdidaktischen Wissen von Lehrpersonen zu bearbeiten. Dabei wird exemplarisch der Unterricht von zwei deutschen Physiklehrern in aufeinanderfolgenden Stunden zum Thema Optik untersucht. Die Studie zeigt wie Videoanalysen genutzt werden können, um Belege für einen Aspekt des fachdidaktischen Wissens der Lehrpersonen zu sammeln: Ihre Nutzung von inhaltlichem Wissen in der Interaktion mit den Schülerinnen und Schülern. In dieser Studie werden drei potentiell wichtige Charakteristika dieses Aspekts des fachdidaktischen Wissens identifiziert: Flexibilität, Reichhaltigkeit und Schülerorientierung. Durch die Gegenüberstellung von Lehrpersonen mit hohem und niedrigem Wissens‐ und Interessenzuwachs wurden potentielle Mechanismen untersucht, durch die dieser Aspekt des fachdidaktischen Wissens die Lernergebnisse von Schülerinnen und Schülern beeinflussen kann. Die Lehrerausbildung in Deutschland betont das inhaltliche Wissen stärker als das fachdidaktische Wissen. Die ausgewählten Fälle beschreiben, welche Unterstützung Lehrpersonen mit einem hohen fachlichen Wissen benötigen, um dieses Wissen so zu verändern, dass es für das Unterrichten genutzt werden kann. © 2012 Wiley Periodicals, Inc.

Science education reform efforts in the Unites States call for a dramatic shift in the way students are expected to engage with scientific concepts, core ideas, and practices in the classroom. This new vision of science learning demands a more complex conceptual understanding of student engagement and research models that capture both the multidimensionality and contextual specificity of student engagement in science. In a unique application of person‐oriented analysis of experience sampling data, we employ cluster analysis to identify six distinct momentary engagement profiles representing different combinations of the behavioral, cognitive, and affective dimensions of student engagement in high school science classrooms. Students spend a majority of their classroom time in one of several engagement profiles characterized by high engagement on one dimension, but low levels on the others. Students exhibited low engagement across all three dimensions of engagement in about 22% of our observations. Full engagement, or high levels across all three dimensions, is the least frequent profile, occurring in only 11% of the observations. Students’ momentary engagement profiles are related in meaningful ways to both the learning activity in which students are engaged and the types of choices they are afforded. Laboratory activities provided especially polarized engagement experiences, producing full engagement, universally low engagement, and pleasurable engagement in which students are affectively engaged but are not engaged cognitively or behaviorally. Student choice is generally associated with more optimal engagement profiles and the specific type of choice matters in important ways. Choices about how to frame the learning activity have the most positive effects relative to other types of choices, such as choosing whom to work with or how much time to take. Results are discussed in terms of implications for practice and the utility of the methodological approach for evaluating the complexities of student engagement in science classrooms. © 2017 Wiley Periodicals, Inc.

The study examines the effects of classroom achievement grouping (AG) practices on the early mathematics performance of language-minority students and compares their mathematics achievement to that of English-speaking majority students. Using a nationally representative database of the USA, both cross-sectional and longitudinal analyses were done. In the cross-sectional analyses we explored the direct effect of grouping practice on students performance, while in the longitudinal analysis we looked at the growth trajectory in mathematics learning. The results of cross-sectional analyses indicated that the effect of AG was negative on the math achievement in 1st and 5th graders. The longitudinal analysis showed a significant negative effect of AG for English Language Learners (ELL). The paper provides the basis for practical guidelines for the grouping practices in mathematics.  相似文献

The question of subject-specificity of achievement motivations is important, both for educational psychology, as well as for educational policy. This study contributes to the investigation of the heterogeneity in achievement motivations in the context of the expectancy-value model. Whereas existing research deals with middle and high school students and their motivations for a range of broad domains, this article focuses on university students (n = 264) and subject domains that are more congruent. We adopt an affect-extended version of the expectancy-value model. Using structural equation methods, we are able to decompose achievement motivations in generic and subject-specific components.  相似文献

As part of a larger project aimed at promoting science and literacy for culturally and linguistically diverse elementary students, this study has two objectives: (a) to describe teachers' initial beliefs and practices about inquiry‐based science and (b) to examine the impact of the professional development intervention (primarily through instructional units and teacher workshops) on teachers' beliefs and practices related to inquiry‐based science. The research involved 53 third‐ and fourth‐grade teachers at six elementary schools in a large urban school district. At the end of the school year, teachers reported enhanced knowledge of science content and stronger beliefs about the importance of science instruction with diverse student groups, although their actual practices did not change significantly. Based on the results of this first year of implementation as part of a 3‐year longitudinal design, implications for professional development and further research are discussed. © 2004 Wiley Periodicals, Inc.

Child physical abuse presents a substantial public health concern with lasting negative consequences for victims. Understanding the variables associated with perpetration can help inform prevention and intervention efforts. The current study examined background and clinical variables in a sample of 195 help-seeking caregivers who were at risk for or had been identified as having engaged in child directed aggression or abuse. We found that caregivers who did (vs. did not) report severe child directed aggression had poorer parenting and reported more drug use. Having a recent allegation of child physical abuse (vs. no allegation) based on official child welfare records was unrelated to parenting, drug and alcohol use, negative affect, parenting stress, or neglect. Structural equation modeling was used to examine the influence of parenting stress on child directed aggression and its effects through negative affect and positive parenting. We found that parenting stress predicted higher negative affect, which was related to greater child directed aggression. Additionally, parenting stress predicted lower positive parenting, which in turn predicted lower child directed aggression. A model including drug and alcohol use did not add to the prediction of child directed aggression. Prediction of neglect using similar variables found that only positive parenting was of import and that parenting stress and negative affect did not contribute to neglect. Implications for future prevention and treatment development efforts with abusive/aggressive caregivers are discussed.  相似文献

This article compares two structural equation modeling fit indexes—Bentler's ( 1990; Bentler & Bonett, 1980) Confirmatory Fit Index (CFI) and Steiger and Lind's (1980; Browne & Cudeck, 1993) Root Mean Square Error of Approximation (RMSEA). These two fit indexes are both conceptually linked to the noncentral chi‐square distribution, but CFI has seen much wider use in applied research, whereas RMSEA has only recently been gaining attention. The article suggests that use of CFI is problematic because of its baseline model. CFI seems to be appropriate in more exploratory contexts, whereas RMSEA is appropriate in more confirmatory contexts. On the other hand, CFI does have an established parsimony adjustment, although the adjustment included in RMSEA may be inadequate.  相似文献
