Many studies in the field of chemical education have emphasized the fact that students at secondary level have considerable difficulties in mastering organic chemistry contents. As a result, they choose to learn these contents in a “rote” way. Taking this fact into consideration, the first aim of our study was to help students in overcoming the aforementioned difficulties by applying new instructional tools—systemic synthesis questions [SSynQs]. To achieve the aim of our research, an experiment with two parallel groups was conducted. The experimental group was taught using [SSynQs] and the control group was taught using a traditional approach. The study included 65 students, 41 males, and 24 females, aged between 17?– 18 years. All the students attended the same high school and were taught by the instructions of the same teacher. The results showed that students from the experimental group achieved higher scores on the final testing than students from the control group. This confirmed the fact that application of [SSynQs] in the educational process improves students’ meaningful learning in organic chemistry domain. Additionally, after conducting an exploratory factor analysis of the obtained data, [SSynQs] were characterized as highly effective tools for assessing students’ meaningful understanding. Furthermore, our study has highlighted and connected two applications of [SSynQs] in the chemistry educational process. Firstly as an instructional tool and secondly as an assessment tool. The important task for future research would be to evaluate a third application of [SSynQs] as a diagnostic tool.  相似文献

Innovative competence, exploration and exploitation: The influence of technological diversification     

Cristina Quintana-García  Carlos A. Benavides-Velasco 《Research Policy》2008,37(3):492-507

This paper investigates how technological diversification influences the rate and specific types of innovative competence. We test a set of hypotheses in a longitudinal study of a sample of biotechnology firms. Our findings provide strong support for the premise that a diversified technology base positively affects innovative competence. Furthermore, technological diversification is found to have a stronger effect on exploratory than on exploitative innovative capability. This empirical evidence suggests that technological diversity may mitigate core rigidities and path dependencies by enhancing novel solutions that accelerate the rate of invention, especially that which departs from a firm's past activities.  相似文献   

The teaching well: Experience, education, and counselling     

Christopher J. Rybak  Lori a. Russell-Chapin 《International journal for the advancement of counseling》1998,20(2):131-139

Wellness classes based on Eastern and Western philosophical concepts were offered to graduate level counselling students as a means of helping them to integrate and clarify their views on counselling. Through experiential activities, students learned to more fully activate inner creative resources for an enhanced sense of wholeness. The concepts and methods learned have practical application to counselling.  相似文献   

Families of children on the autism spectrum: experience of daily life and impact of parent education     

Jasmina Stošić  Jasmina Frey Škrinjar  David Preece 《Support for Learning》2020,35(2):205-221

Information and support for families of children on the autism spectrum is limited in south-east Europe. A three-year project, Equity and Social Inclusion Through Positive Parenting (ESIPP), was established to develop and provide parent education (PE) in autism for families in Croatia, Cyprus and North Macedonia. This paper presents findings from Croatia regarding family life and the impact of PE. Data were collected via pre- and post-PE questionnaires and semi-structured interviews. Participants discussed the impact of autism on family life, the difficulty of obtaining a diagnosis, the importance of family support (and varying experience of formal support), common experiences of stigma and social exclusion and concerns for the future. The value and benefit of PE is identified, and recognition of its impact within Croatia has ensured its ongoing provision.  相似文献   

Children’s Home Numeracy Environment Predicts Growth of their Early Mathematical Skills in Kindergarten     

María Inés Susperreguy  Sabrina Di Lonardo Burr  Chang Xu  Heather Douglas  Jo-Anne LeFevre 《Child development》2020,91(5):1663-1680

This study investigated the longitudinal associations between children’s early mathematics and their home numeracy environment (HNE). Chilean children from families who varied widely in socioeconomic status were assessed at the beginning and end of prekindergarten in 2016 (N = 419, M_age = 4:7 [years:months]), and at the end of kindergarten in 2017 (N = 368, M_age = 5:10). Children whose parents provided frequent operational numeracy activities (e.g., learning simple sums) at prekindergarten showed better arithmetic performance and growth in nonsymbolic and symbolic number comparison at the end of kindergarten. Parents’ knowledge of number-related games predicted children’s arithmetic skills and growth in nonsymbolic number comparison. These findings underscore the persistent relations between the HNE and the development of children’s mathematical skills.  相似文献   

Differences in maturity,morphological and physical attributes between players selected to the primary and secondary teams of a Portuguese Basketball elite academy     

Sérgio Ramos  Anna Volossovitch  António Paulo Ferreira  Isabel Fragoso  Luís Massuça 《Journal of sports sciences》2019,37(15):1681-1689

The present study aims (i) to compare the maturational, morphological and fitness attributes of young basketball players of primary and secondary teams of an elite basketball academy, and (ii) to identify the set of morphological and fitness attributes which better discriminate the players from the two teams. A total of 116 male basketball players of an elite basketball academy were divided into primary (team A) and secondary (team B) teams in two age groups (U-14 and U-16). All the players were evaluated during two consecutive seasons and data related to players’ practice experience, maturational, morphological and fitness attributes were collected at the beginning of the competition period. The results of the study suggest that: (i) in both age categories, team A players were older, more mature, bigger in size and had greater fitness profiles than team B players; (ii) stature and abdominal resistance were identified as discriminant attributes for youth basketball player performance; (iii) aerobic capacity for U-14 and agility for U-16 were identified as specific discriminant attributes for performance in youth basketball. Coaches are recommended to avoid premature talent identification and provide players with opportunities to progress through the talent pathway, at least until U-16 age category.  相似文献   

Inbreeding and Research Productivity Among Sociology PhD Holders in Portugal     

Tavares  Orlanda  Sin  Cristina  Lança  Vasco 《Minerva》2019,57(3):373-390

In Portugal, research productivity is nowadays essential for the positive assessment of academics, research units and study programmes. Academic inbreeding has been highlighted in the literature as one of the factors influencing research productivity. This paper tests the hypothesis that inbreeding is detrimental for research productivity, measured through the number of publications listed in Scopus. The study resorts to a database provided by the national Agency for Assessment and Accreditation of Higher Education (A3ES), which comprises all academics teaching in all Portuguese institutions in the academic year 2015/2016. The sample selected for the analysis contains all academics with a PhD in Sociology (N=289). The study uses a special regression model for the analysis: the negative binomial logit hurdle. This was necessary given the large amount of academics with no publications or citations in Scopus, which were the dependent variables to assess research performance. The analysis provides separate results for the probability of inbred academics of having no papers/citations, and for the probability of producing more papers/citations than the non-inbred. Findings suggest that academic inbreeding, defined at the institutional level, has no negative effect on research productivity, contrary to what was expected. However, when defined at the national level, academic inbreeding is detrimental for the recognition and the impact of research: academics with a foreign PhD are more likely to have citations compared to academics who obtained their PhD in Portugal. A tendency was also noted that inbreeding might be more detrimental to research productivity in faculties of Economics than in Social Sciences and Humanities.

Motivation,satisfaction and loyalty in the case of a film festival: differences between local and non-local participants     

Andrea Báez-Montenegro  María Devesa-Fernández 《Journal of Cultural Economics》2017,41(2):173-195

The last few years have seen a remarkable increase in the number of cultural events and festivals. The increasing competitiveness among them and the need to safeguard their future viability make it necessary to identify factors that not only attract and satisfy new participants, but also retain previous attendees. Accordingly, this article examines the relations between motivation, satisfaction and loyalty in the case of a cinema event the Valdivia International Film Festival (Chile), distinguishing, in turn, between local attendees and visitors. To achieve this goal, a structural equation modelling is performed based on the data obtained through a survey conducted among festival attendees. The results show there are different motivations for attending a festival (leisure, professional motives and cinema) and that some directly affect satisfaction and loyalty. Similarly, satisfaction is presented as an unquestionable antecedent of loyalty, the latter being measured by means of different concepts. Finally, the research highlights some significant differences between residents and tourists and seems to point to the existence of a kind of cultural tourism focused on an interest in the cinema, which contributes to the festival’s continuity and sustainability. All of this allows us to extract some implications for the managers of this type of event and for those responsible for the destination’s cultural and tourist policy.  相似文献   

Assessing practice-based influences on adolescent psychosocial development in sport: the activity context in youth sport questionnaire     

Enrique García Bengoechea  Catherine M. Sabiston  Philip M. Wilson 《Journal of sports sciences》2017,35(1):56-64

The aim of this study was to provide initial evidence of validity and reliability of scores derived from the Activity Context in Youth Sport Questionnaire (ACYSQ), an instrument designed to offer a comprehensive assessment of the activities adolescents take part in during sport practices. Two studies were designed for the purposes of item development and selection, and to provide evidence of structural and criterion validity of ACYSQ scores, respectively (N = 334; M age = 14.93, SD = 1.76 years). Confirmatory factor analysis (CFA) supported the adequacy of a 20-item ACYSQ measurement model, which was invariant across gender, and comprised the following dimensions: (1) stimulation; (2) usefulness-value; (3) authenticity; (4) repetition-boredom; and (5) ineffectiveness. Internal consistency reliability estimates and composite reliability estimates for ACYSQ subscale scores ranged from 0.72 to 0.91. In regression analyses, stimulation predicted enjoyment and perceived competence, ineffectiveness was significantly associated with perceived competence and authenticity emerged as a predictor of commitment in sport. These findings indicate that the ACYSQ displays adequate psychometric properties and the use of the instrument may be useful for studying selected activity-based features of the practice environment and their motivational consequences in youth sport.  相似文献
