ETAS: an instrument for measuring attitudes towards learning English with technology     

Sharon Kearney  Silvia Gallagher  Brendan Tangney 《Technology, Pedagogy and Education》2020,29(4):445-461

ABSTRACT

Information and communication technology (ICT) increasingly is utilised in second-level English education, aiming to engage students, yet quantitative instruments for evaluating the impact of technology-mediated learning experiences are lacking. This article presents the rationale, development and psychometric analysis of the English and Technology Attitudes Scale (ETAS): a 19-item instrument designed to evaluate students’ attitudes towards English and technology and monitor changes. Five constructs are measured: behavioural engagement; technology confidence; English confidence; emotional engagement; and learning with technology. Using the ETAS, this study revealed insights to Irish students’ (n = 419) attitudes that can inform approaches to teaching and learning with ICT. Despite strong technology confidence, a high proportion of students report poor attitudes towards learning English with technology. Moreover, males have significantly more positive attitudes towards learning English with technology, yet females have significantly higher engagement in English. These findings demonstrate both the need for and the usefulness of this instrument.  相似文献   

Identifying the Item Hierarchy and Charting the Progression across Grade Levels: Surveying Taiwanese Students’ Understanding of Scientific Models and Modeling     

Silvia Wen-Yu Lee 《International Journal of Science and Mathematics Education》2018,16(8):1409-1430

The purpose of this study was, first, to understand the item hierarchy regarding students’ understanding of scientific models and modeling (USM). Secondly, this study investigated Taiwanese students’ USM progression from 7th to 12th grade, and after participating in a model-based curriculum. The questionnaire items were developed based on 6 aspects of USM, namely, model type, model content, constructed nature of models, multiple models, change of models, and purpose of models. Moreover, 10 representations of models were included for surveying what a model is. Results show that the purpose of models and model type items covered a wide range of item difficulties. At the one end, items for the purpose of models are most likely to be endorsed by the students, except for the item “models are used to predict.” At the other end, the “model type” items tended to be difficult. The students were least likely to agree that models can be text, mathematical, or dynamic. The items of the constructed nature of models were consistently located above the average, while the change of models items were consistently located around the mean level of difficulty. In terms of the natural progression of USM, the results show significant differences between 7th grade and all grades above 10th, and between 8th grade and 12th grade. The students in the 7th grade intervention group performed better than the students in the 7th and 8th grades who received no special instruction on models.  相似文献   

Expanding Notions of Digital Access: Parents' Negotiation of School-Based Technology Initiatives in New Immigrant Communities     

Silvia Noguerón-Liu 《Equity & Excellence in Education》2017,50(4):387-399

Initiatives to integrate technology in schools are continuously increasing, with efforts to bridge the “homework gap” and provide technology access in low-income households. However, it is critical to include nondominant parents in technology adoption decisions in order to avoid mirroring past patterns of inequality in home-school relationships. This study examines the digital access, use, and beliefs of Spanish-dominant immigrant parents, whose children attended a school in early stages of 1:1 (one laptop, one child) and BYOD (bring-your-own-device) initiatives. Informed by critical and ecological approaches to family literacy and technology use, the analysis compares the cases of eight parents attending technology workshops facilitated by the researcher and looks at the factors and contexts shaping their digital access and use and their shifts in access over two years. The analysis then narrows down to their beliefs about the use of school-provided devices. Findings illustrate the diversity in device use and customization in families with similar immigration trajectories, showing how economic factors, education, and established livelihoods in the community shaped their decisions to obtain devices and Internet connectivity. Cases also show the crucial role of the school in providing computers and technology training; however, decisions about taking school devices home and supervising children's activity were shaped by parents' beliefs about their roles supporting their children's moral education, and their existing family practices. Implications for family literacy programs and outreach for digital equity in new migration settings are discussed.  相似文献

The Latent Variable-Autoregressive Latent Trajectory Model: A General Framework for Longitudinal Data Analysis     

Silvia Bianconcini  Kenneth A. Bollen 《Structural equation modeling》2018,25(5):791-808

In recent years, longitudinal data have become increasingly relevant in many applications, heightening interest in selecting the best longitudinal model to analyze them. Too often, traditional practice rather than substantive theory guides the specific model selected. This opens the possibility that alternative models might better correspond to the data. In this paper, we present a general longitudinal model that we call the Latent Variable-Autoregressive Latent Trajectory (LV-ALT) model that includes most other longitudinal models with continuous outcomes as special cases. It is capable of specializing to most models dictated by theory or prior research while having the capacity to compare them to alternative ones. If there is little guidance on the best model, the LV-ALT provides a way to determine the appropriate empirical match to the data. We present the model, discuss its identification and estimation, and illustrate how the LV-ALT reveals new things about a widely used empirical example.  相似文献   

A systematic review of trends and findings in research employing drawing assessment in science education

ABSTRACT

In this study, we reviewed 76 journal articles on employing drawing assessment as a research tool in science education. Findings from the systematic review suggest four justifications for using drawing as a type of research tool, including assessment via drawing as (a) an alternative method considering young participants’ verbal or writing abilities, and affective or economic reasons, (b) a unique method that can reveal aspects not easily measured by other methods, (c) a major method that reflects characteristics of science subjects, and (d) a formative assessment to diagnose students’ ideas to benefit their learning. Furthermore, five research trends of studies using drawing as assessment tools are identified, including: (a) students’ conceptions of scientists from the Draw-a-Scientist-Test (DAST) and evolving studies, (b) students’ understanding or mental models of science concepts, (c) participants’ conceptions of science learning or teaching, (d) students’ inquiry abilities and modelling skills via drawing, and (e) technology to support drawing. For each trend, we synthesised and commented on the current findings. A framework conceptualising phases and issues when designing research and instruments employing drawing assessments is proposed. The review provides insights into the design and future direction of research employing drawing assessments in science education.  相似文献   

Self-Construals and Social Adjustment in Immigrant and Nonimmigrant Early Adolescents: The Moderating Role of Executive Functioning     

Diana Miconi  Ughetta Moscardino  Gianmarco Altoè  Silvia Salcuni 《Child development》2019,90(1):e37-e55

This study examined whether executive functions (EFs) moderate the association between independent and interdependent self-construals and social adjustment in 488 Moroccan, Romanian, and Italian preadolescents (ages 11–13) in Italy. Participants were assessed using self-report questionnaires and standardized EF tasks. Better working memory was related to increased social competence across all groups. High levels of inhibitory control were found to enhance the positive relation between interdependence and prosocial behavior for native Italian youth, and between interdependence and social competence for Moroccan preadolescents. High levels of cognitive flexibility boosted the interdependence–social competence link for the immigrant groups, whereas among native Italian preadolescents, the interdependence–social competence link was significant at low levels of flexibility. Implications for developmental theory and practice are discussed.  相似文献   

Psychometric Properties of the ECERS-R Among an Epidemiological Sample of Preschools     

Marília Mariano  Sheila C. Caetano  Anderson Ribeiro da Silva  Pamela J. Surkan  Silvia S. Martins  Hugo Cogo-Moreira 《Early education and development》2019,30(4):511-521

Research Findings: The Early Childhood Environment Rating Scale–Revised (ECERS-R) is widely used to evaluate the quality of early childhood education and its association with child development. However, the psychometric properties of the ECERS-R are not well established. Consequently, in this study we tested 3 different factor solutions of the ECERS-R using models sourced from the existing literature (featuring 1-, 2-, and 3-correlated-factor solutions) and applying confirmatory factor analysis to data from the epidemiological sample of the Embu Pre-school Mental Health Study (n = 1,292 children). Alternative measures of child education quality (such as teacher-to-child ratio) were also analyzed. The confirmatory factor analysis returned good fit indices for both the unidimensional and 3-correlated-factor solution models. Practice or Policy: This study showcases different applications of the ECERS-R, both the full and shortened versions. These findings are particularly important for improving ECERS-R guidelines for researchers, professionals, and policymakers.  相似文献   

R&D, innovation and microeconomic growth: a case study     

B. Schott 《Research Policy》1974,2(4):380-403

Although Rollei's camera sales grew as a result of postwar increases in income, its traditional product lines came under competitive pressure in international markets in the mid-1950s from lower-priced Japanese cameras of the same type, and from the newly-developed 35mm camera. By 1964, Rollei's sales and exports were stagnating and profits had disappeared. However, the policy of new management began in 1965 to widen and renew the company's product range through a vigorous programme of R&D, and a strong marketing effort. By 1971, 84% of Rollei's sales were products which had not existed in 1965, and these new products enabled Rollei to remain competitive in the critically important export market.  相似文献
