Transversal traits in science education research relevant for teaching and research: A meta‐interpretative study     

J. Bernardino Lopes  António Alberto Silva  José P. Cravino  Nilza Costa  Luís Marques  Carlos Campos 《科学教学研究杂志》2008,45(5):574-599

This study is a meta‐interpretative analysis that focuses on research conducted and published by other researchers. Concepts central to this study include global practical relevance, curriculum design, and formative situation. We analyzed 35 studies selected from 374 published studies in the years 2000 and 2001 in three journals referenced in the International Scientific Index. Using a replicable methodology developed specifically for this research, we found evidence of s clusters of variables that suggest the existence of transversal traits in the 35 science education research studies. These results form a reference framework of theoretical and practical knowledge relevant for research and practice pertaining to teaching and learning science. © 2008 Wiley Periodicals, Inc.

The effect of academic self-concept on ADHD and antisocial behaviors in early adolescence     

Pisecco S  Wristers K  Swank P  Silva PA  Baker DB 《Journal of learning disabilities》2001,34(5):450-461

Using structural equation modeling techniques, we evaluated the effect of academic self-concept (ASC) on the development of attention-deficit/hyperactivity disorder (ADHD) and antisocial behaviors in early adolescence. Participants (n = 445) were recruited from the Dunedin Multidisciplinary Health and Development Research study. Eligibility was determined by the presence of complete data for the following variables at the specified time periods: reading at age 7, teacher reports of ADHD and antisocial behaviors at age 7, self-ratings of ASC at ages 9 and 11, and teacher reports of ADHD and antisocial behaviors at age 13. The results indicated that ASC is an important construct that directly contributes to the development of antisocial behaviors rather than to symptoms of ADHD. The results also indicated that children's early history of behavioral problems and academic performance contribute to the development of a more robust understanding of the impact of ASC on the development of disruptive behaviors in early adolescence.  相似文献   

Combining Operations Management and Information Systems Curricula: Assessing Alumni Preparations for the Workforce     

David Silva  Kathleen L. McFadden 《Decision Sciences Journal of Innovative Education》2005,3(2):307-321

The purpose of this study is to explore how well a curriculum that combines operations management and information systems uniquely prepares students for the workforce. To address our research questions, a Web‐based survey was developed. We sent our survey to 203 alumni that graduated from the Department of Operations Management and Information Systems at Northern Illinois University. We assess alumni perceptions of how well our department prepared them in general and technical skills as well as how important these skills were in their current position. We investigate factors useful in predicting preparedness for both general business and technical skills. Overall, students felt prepared in most of the important skills we studied. We also found a significant positive relationship between alumni‐perceived importance of general and technical skills and perceived preparedness for those skills. More recent graduates felt the most prepared for both general business and technical skills. Our findings highlight the importance of general skills for future advancement and caution educators against overemphasizing currently popular technical tools at the expense of teaching the more general business skills. Results presented here provide new knowledge for curriculum designers at the intended institution and lessons for other schools. This research also provides a methodology or process that can be repeated at other institutions that combine information systems with operations management, or with other functions such as decision sciences or accounting. An implication of the results is that schools redesigning their programs may want to consider a curriculum that combines operations management and information systems.  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   

Outsourcing as an Improvisation: A Case Study in Latin America     

Leiser O. Silva 《The Information Society》2002,18(2):129-138

This article discusses how political factors influence the outcome of improvisations. Improvisations are unexpected actions rooted on intuition and aimed at solving particular crisis. It is argued that the effectiveness of an act of improvisation is greatly influenced by political factors. Those performing the improvisation require being in a position of power,and the discourse that follows the improvisation has political connotations. The argument is developed through the discussion of concepts of power and improvisation and through the analysis of a case study. The case study concerns the outsourcing of the administrative information systems of the two largest hospitals of a Latin American country. The contributions of the article are twofold: (1) It identifies the relationship between power and improvisations and (2) it draws practical lessons on how to manage outsourcing.  相似文献

Stereotypy of spatial movements during noncontingent and contingent reinforcement     

Francisco J. Silva  Joseph J. Pear 《Learning & behavior》1995,23(3):245-255

The degree of stereotypy in the movement patterns of 3 pigeons during noncontingent and contingent periodic food reinforcement was quantified by analyzing the distribution of turning angles, and by using information and Fourier analyses. The results indicated that (1) movement patterns were less stereotyped during noncontingent than during contingent reinforcement, (2) a reversal to noncontingent reinforcement resulted in a degree of stereotypy comparable to that during the first phase of noncontingent reinforcement, (3) movement patterns were maximally stereotyped immediately after food withdrawal and generally became less stereotyped as reinforcement approached, regardless of whether reinforcement was noncontingent or contingent, and (4) higher frequency movements generally accounted for more variance in the movements during contingent than during noncontingent reinforcement. Greater stereotypy in the movements during contingent reinforcement was likely due to a greater probability that similar movements were reinforced during contingent reinforcement. Momentary changes in the stereotypy of the movements within the interfood interval might reflect changes in the level of arousal.  相似文献
