Trademarks as an indicator of innovation and industrial change   总被引：1，自引：0，他引：1  

Sandro Mendonça  Tiago Santos Pereira 《Research Policy》2004,33(9):1385-1404

As innovation becomes an ever more central issue for the development of firms and world economies, so the need for improved assessments of innovative performance grows more urgent. This paper suggests that trademark analysis can contribute in capturing relevant aspects of innovation phenomena and the process of industrial change. We propose trademarks as a complementary indicator in the portfolio of available empirical tools of innovation studies and industrial dynamics. Our empirical exploration is based on a study of community trade marks (CTM), an intellectual property right granted in the European Union, and draws on recent research on trademarking trends in Portugal. Quantitative as well as qualitative data, including survey data from a representative sample of Portuguese manufacturing and services firms, are used to identify the advantages and limitations of this indicator.  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

The purpose of this study was to analyse the physical and technical performances of professional tennis players during official matches. The trajectories of eight players were obtained during matches, using an automatic tracking method. The distances covered and technical performances were analysed for the first and second sets. The athletes covered (mean ± standard deviation) a total of 1702.4 ± 448.2 m in the first set, 1457.6 ± 678.1 m in the second set and 3160.0 ± 880.1 in the entire match. No differences were found between the sets for the physical variables (lateral and forward displacements, distance covered per rally, per game and per set, and the percentage of time spent in each range of velocity). However, the distances covered by the athletes during the rallies in which they were serving (median = 5.2; interquartile range (IQR) = 6.7 m) were statistically smaller than when they were returning (median = 6.2; IQR = 7.7 m). Forehand ground stroke proficiency decreased from the first (mean ± standard deviation: 75.2 ± 4.11%) to the second set (mean ± standard deviation = 65.5 ± 14.3%). In conclusion, tennis players did not present reduced physical performance from the first to the second set.  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   

Letter names and sounds: their implications for the phonetisation process     

Cristina Silva  Tiago Almeida  Margarida Alves Martins 《Reading and writing》2010,23(2):147-172

Our aim was to analyse the impact of the characteristics of words used in spelling programmes and the nature of instructional guidelines on the evolution from grapho-perceptive writing to phonetic writing in preschool children. The participants were 50 5-year-old children, divided in five equivalent groups in intelligence, phonological skills and spelling. All the children knew the vowels and the consonants B, D, P, R, T, V, F, M and C, but didn’t use them on spelling. Their spelling was evaluated in a pre and post-test with 36 words beginning with the consonants known. In-between they underwent a writing programme designed to lead them to use the letters P and T to represent the initial phonemes of words. The groups differed on the kind of words used on training (words whose initial syllable matches the name of the initial letter—Exp. G1 and Exp. G2—versus words whose initial syllable is similar to the sound of the initial letter—Exp. G3 and Exp. G4). They also differed on the instruction used in order to lead them to think about the relations between the initial phoneme of words and the initial consonant (instructions designed to make the children think about letter names—Exp. G1 and Exp. G3—versus instructions designed to make the children think about letter sounds—Exp. G2 and Exp. G4). The 5th was a control group. All the children evolved to syllabic phonetisations spellings. There are no differences between groups at the number of total phonetisations but we found some differences between groups at the quality of the phonetisations.  相似文献   

Developing a Reflective Practitioner Through the Connection Between Educational Research and Reflective Practices     

Dawn Del Carlo  Holly Hinkhouse  Leah Isbell 《Journal of Science Education and Technology》2010,19(1):58-68

This paper outlines the connection between qualitative research methods in education and teacher reflective practices as they relate to Valli’s (Reflective teacher education: cases and critiques. State University of New York Press, Albany, 1992; Peabody J Educ 72(1): 67–88, 1997) model of reflection. Using the authors’ own experiences in performing and guiding educational research, and existing research in the field of teacher education pertaining to reflective practitioners, explicit connections are made between the two paradigms. These connections illustrate the importance of integrating authentic research experiences into the teacher education curriculum outside the context of methods courses, much like models established in the sciences.  相似文献   

The role of new technologies in competence teaching in higher education： The case of accounting     

M Del Mar Marin Sanchez Alicia Mateos Ronco 《美中教育评论》2010,(3):53-61

The Spanish educational system will require certain changes in order to achieve the Bologna objectives for the European Higher Education Area, including a more professional profile, with new activities and roles for both students and teachers, who must assume new skills that will affect concepts and attitudes related to the teaching and learning processes within the framework of training projects. However, students must also take a leading role in the educational process by adopting independent, meaningful and cooperative learning methods. This process will imply a notable change of mindset for the typical Spanish students and will involve a high degree of collaboration between students and teachers. Teachers will have to choose suitable methodologies for achieving those objectives, within the academic framework and considering the characteristics of professional training in skills. In addition, they must create the appropriate structural and organizational conditions to carry out these activities （class size, space, educational organization, etc.）. This paper describes the authors＇ experience in designing learning methodologies for the teaching of accountancy in the business administration degree course at the Polytechnic University of Valencia. The paper is divided into three parts. The first part describes the methodology designed for teaching accounting, based on PBL （problem-based learning）, compiled with Internet-based technologies. We analyze its use and evolution in two accounting subjects in the first and the fourth years of the degree. The second part presents the results for each subject in these years. The authors also point out the differences between students who chose the learning methodology described and those who used the traditional approach. The final part of the paper presents the conclusions obtained from the statistical treatment of the results and the analysis of different options for correlating the information obtained. These results show that there is a direct correlation between the use of an active learning model--through the teaching methodology--and obtaining satisfactory exam results in the subject. Finally, the authors analyze these results and consider how they should be used for evaluating the suitability of the methodology and to determine whether it is necessary to redesign the methodology to fit in with the characteristics, conditions and limitations of the teaching and learning processes.  相似文献
