High School Internships: Utilizing a Community Cultural Wealth Framework to Support Career Preparation and College-Going Among Low-Income Students of Color     

Marco A. Murillo  Karen Hunter Quartz  Jaime Del Razo 《Journal of Education for Students Placed at Risk》2017,22(4):237-252

This article investigates the experience of 229 low-income students of color who participated in an innovative high school internship program between 2011 and 2015. Using mixed methods (interviews, observations, and survey), the authors aim to understand the types of knowledge, information, and supports these students develop and expand in relation to careers and the college-going process. The authors draw on students' community cultural wealth to highlight the way the internship program supports students' aspirational, navigational, linguistic, resistant, and social capital.  相似文献   

Linguistic and pedagogical factors affecting children's understanding of arithmetic word problems: A comparative study     

Glendon A. Lean  McKenzie A. Clements  Gina Del Campo 《Educational Studies in Mathematics》1990,21(2):165-191

2493 children aged from 5 to 15 years in 114 classes in 25 primary schools were asked to do a similar set of 22 arithmetic word problems. 1195 of the children were in Grades K through 6 in Victorian schools (Australia) and 1298 were in Grades 4 through 6 in Papua New Guinea (PNG) schools. For both samples the questions were posed in English. This was the first language for most children in the Victorian sample but, for the PNG sample, English was usually the second, third, or even fourth language (even though it is the language of instruction in PNG schools). While the test instrument was based on widely accepted information processing models of how children solve arithmetic word problems, the data obtained were not so much in accord with these models as with psycholinguistic theories on children's acquisition of polarised comparative pairs (like more and less). The data also indicate that children from the two samples used similar strategies and made similar errors, with the order of relative difficulty being the same for both samples, the main factor determining difficulty being the semantic structure of the questions. Differences in performance between corresponding grades from the two samples can be attributed to differences in the degree of English language competence rather than to numerical facility.  相似文献   

Focusing Improvement and Quality Assurance: Work Samples as Authentic Performance Measures of Prospective Teachers’ Effectiveness     

Andrew A. McConney  Mark D. Schalock  H. Del Schalock 《Journal of Personnel Evaluation in Education》1998,11(4):343-363

The authors suggest that the gap between common evaluation practice in teacher preparation and the consensus reform goal of high levels of student learning for all students is an impediment to reinventing teacher preparation, professional development, and the professionalization of teaching. In the context of Oregons six-year-old educational transition to a standards-based design for schools and schooling, prospective teachers in Oregon have, since 1989, been required to design, develop, and implement teacher work samples as credible evidence of their effectiveness in fostering student learning as a condition for recommendation for an initial teaching license. This article describes teacher work sample methodology and evidence for its reliability and validity in evaluating the performance of prospective teachers. In short, this article describes a methodology that responds to one critical part of the National Commission on Teaching and Americas Futures challenge to reinvent teacher education and improve student learning.  相似文献   

Students' perceptions of academic dishonesty in the chemistry classroom laboratory     

Dawn I. Del Carlo  George M. Bodner 《科学教学研究杂志》2004,41(1):47-64

Although the literature on both academic dishonesty and scientific misconduct is extensive, research on academic dishonesty has focused on quizzes, exams, and papers, with the virtual exclusion of the classroom laboratory. This study examined the distinctions undergraduate chemistry majors made between academic dishonesty in the classroom laboratory and scientific misconduct in the research laboratory. Across the spectrum of undergraduate chemistry courses, from the introductory course for first‐semester chemistry majors to the capstone course in instrumental analysis, we noted that students believe the classroom lab is fundamentally different from a research or industrial lab. This difference is so significant that it carries over into students' perceptions of dishonesty in these two environments. © 2003 Wiley Periodicals, Inc. J Res Sci Teach 41: 47–64, 2004  相似文献   

Do you know what I'm thinking? A comparison of teacher and parent perspectives of underachieving gifted students' attitudes     

Del Siegle  Lisa DaVia Rubenstein  D. Betsy McCoach 《Psychology in the schools》2020,57(10):1596-1614

The Achievement Orientation Model posits students are motivated to do well in school when they believe they have the necessary skills to perform a task (self-efficacy), find the task meaningful (goal valuation), and see their environment as supportive. When these factors are present, students self-regulate and achieve. We examined these factors from underachieving gifted students', their parents', and teachers' perspectives. Results indicated teachers recognize students who are confident and not confident about their abilities to be academically successful; however, they are less able to recognize when students value the work they are encountering in school. Parents' perceptions of students' attitudes more closely correlated with students' perceptions than teachers' perceptions correlated with students' perceptions. Teachers and parents appeared to base their perception of the importance students hold for school on their perception of students' self-regulation. Furthermore, gender differences existed in students' perceptions. Females' self-efficacy scores were statistically lower than males' self-efficacy scores, and males' self-regulation scores were lower than females' self-regulation scores. We provide suggestions for how school psychologists may use these findings to (a) collect important information from students, teachers, and parents, (b) interpret these data to identify underlying influential factors, and (c) guide the development of appropriate interventions to address student underachievement.  相似文献   

Study and Conservation of the St. Nicola's Basilica Mosaics (Bari,Italy) by Photogrammetric Survey: Mapping of Polychrome Marbles,Decorative Patterns and Past Restorations     

Giovanna Fioretti  Pasquale Acquafredda  Silvia Calò  Mariagrazia Cinelli  Germano Germanò  Alessandro Laera 《文物保护研究》2020,65(3):160-171

ABSTRACT

This present work focuses on the mapping of marbles, decorative patterns and area of the mosaics of the St. Nicola’s Basilica in Bari (Italy) by their photogrammetric survey. The extraordinary importance of these mosaics is due to the stylistic uniqueness and the undisputed workmanship and to the employed materials for tesserae. These mosaics include the white and polychrome marbles, used in the Roman age and reused in medieval artistic production, and imitation stones used as substitutes during the past restorations. The digital survey was realised by the photogrammetric reconstruction of mosaics collecting a photo dataset, after the mosaics redrawing by an image processing software and finally implemented it with lithological identification marbles. It allowed to obtain a punctual mapping of materials, through which to identify original areas and restoration areas, decorative patterns, recurring geometries. The research carried out, supported by the photogrammetric reconstruction as established method for high resolution digital reproduction and mapping, not only ensures the conservation and improvement of the enjoyment of the mosaic floors of the St. Nicola’s Basilica, but allows to conduct studies on materials, decorative patterns and restoration areas directly on the digitized product.  相似文献   

More Than Growth Mindset: Individual and Interactive Links Among Socioeconomically Disadvantaged Adolescents’ Ability Mindsets,Metacognitive Skills,and Math Engagement     

Ming-Te Wang  Cristina D. Zepeda  Xu Qin  Juan Del Toro  Kevin R. Binning 《Child development》2021,92(5):e957-e976

This article used self-regulated learning as a theoretical lens to examine the individual and interactive associations between a growth mindset and metacognition on math engagement for adolescent students from socioeconomically disadvantaged schools. Across three longitudinal studies with 207, 897, and 2,325 11- to 15-year-old adolescents, students’ beliefs that intelligence is malleable and capable of growth over time only predicted higher math engagement among students possessing the metacognitive skills to reflect upon and be aware of their learning progress. The results suggest that metacognitive skills may be necessary for students to realize their growth mindset. Thus, growth mindsets and metacognitive skills should be promoted together to capitalize on the mutually reinforcing effects of each, especially among students in socioeconomically disadvantaged schools.  相似文献   

Evaluating Instructor Technology Integration in Community and Technical Colleges: A Performance Evaluation Matrix     

Marietta Del Favero  Janice M. Hinson 《Community College Journal of Research & Practice》2013,37(5):389-408

The press for implementing technology based instructional delivery systems in community and technical colleges is well documented. Yet faculty face numerous challenges in integrating technology into instruction (AL-Bataineh & Brooks, 2003 AL-Bataineh , A. & Brooks , L. ( 2003 ). Challenges, advantages, and disadvantages of instructional technology in the community college classroom . Community College Journal of Research and Practice , 27 , 473 – 484 .[Taylor & Francis Online] , [Google Scholar]; Groves & Zemel, 2000 Groves , M. & Zemel , P. ( 2000 ). Instructional technology adoption in higher education: An action research case study . International Journal of Instructional Media , 27 ( 1 ), 57 – 66 . [Google Scholar]; Khoury, 1997 Khoury , R. M. ( 1997 ). The unkept promise . Community College Week , 10 ( 1 ), 4 – 6 . [Google Scholar]). Stimulating faculty ownership in technology, diffusion of technology use throughout institutions, and linking technology use to the faculty reward system are key concerns addressed in this proposed tool for evaluating faculty technology integration performance. The tool is based on research on faculty development (Howery, 1997 Howery , C. B. ( 1997 ). Recognizing and rewarding the professional and scholarly work of sociologists . Unpublished report to the Council of the American Sociological Association . [Google Scholar]) and the technology adoption process (Hall, Loucks, Rutherford, & Newlove, 1975 Hall , G. E. , Loucks , S. F. , Rutherford , W. L. , & Newlove , B. W. ( 1975 ). Levels of use of the innovation: A framework for analyzing innovation adoption . The Journal of Teacher Education , 26 ( 1 ), 52 – 56 .[Crossref], [Web of Science ®] , [Google Scholar]). Stimulating development of faculty expertise linked to technology goals is the goal of applying the tool.  相似文献   

A Complex quest: The development and research of underachievement interventions for gifted students     

Lisa Davia Rubenstein  Del Siegle  Sally M. REIS  D. Betsy Mccoach  Meredith Greene Burton 《Psychology in the schools》2012,49(7):678-694

The seeming lack of motivation of many academically gifted students is an area of frustration and concern for many parents, teachers, and psychologists. This article explores two studies in which researchers designed interventions to improve academic achievement. Both interventions were created using the Achievement‐Orientation Model. The first study matched the intervention to the student and found that the students' grades increased over the intervention period, t(45) = 2.56, p = .014, d = .38. Students using treatments linked to goal valuation and environmental perceptions showed the greatest academic grade growth; the self‐efficacy and self‐regulation groups showed little or no grade improvement. Building on the finding that goal valuation was important, the second study used a mixed‐methods design to pilot an intervention focused on goal valuation and student autonomy. The results of this study were mixed, as the intervention appeared to help two of the three students. Although these studies offer further insight into possibilities for promoting academic achievement among gifted students, further research examining how to best support and foster academic achievement in underachieving gifted students is needed. © 2012 Wiley Periodicals, Inc.  相似文献   

Material characterization,stratigraphy, textures,and painting techniques of the mural painting The Allegory of the Industrial Development of São Paulo by Fulvio Pennacchi     

Patricia Marques Magon  Eliane Aparecida Del Lama 《文物保护研究》2013,58(7):387-396

ABSTRACT

This work presents a study of samples of the mural painting The Allegory of the Industrial Development of São Paulo (Alegoria ao Desenvolvimento Industrial Paulista), made in the city of São Paulo, Brazil, by the artist Fulvio Pennacchi. Using transmitted light petrographic microscopy, scanning electron microscopy coupled with energy dispersive X-ray spectrometry, and X-ray fluorescence, the stratigraphy, the textures, the mineralogy, and the chemical compositions of the mural were established; therefore the painting techniques, pigments, and materials applied by the artist were identified. The mural was painted with the fresco technique and variations. This technique involves the use of materials of mineral origin, both in the support and for the pigments. About the artist’s relevance, Fulvio Pennacchi is considered an important muralist of his time, being one of the pioneers in the production of frescoes in Brazil. The mural, measuring approximately 11?×?6?m, painted in 1954, was removed from where it was originally made, in consequence of a fire that affected the place. Specialized engineers transported it, and today it is stored awaiting restoration. The data presented here can support the process of restoration of the mural, as well as contribute to the improvement of protocols for the analysis of works of art, and to the historical record of mural painting techniques over time.  相似文献
