Teaching future teachers basic astronomy concepts—seasonal changes—at a time of reform in science education     

Ricardo Trumper 《科学教学研究杂志》2006,43(9):879-906

Bearing in mind students' misconceptions about basic concepts in astronomy, the present study conducted a series of constructivist activities aimed at changing future elementary and junior high school teachers' conceptions about the cause of seasonal changes, and several characteristics of the Sun–Earth–Moon relative movements like Moon phases, Sun and Moon eclipses, and others. The activities and results concerning the cause of seasonal changes are reported. Both the experimental class and the control groups improved their grasp of basic astronomy concepts statistically significantly, although the experimental class made the most impressive progress of all. Regarding subjects relevant to this study (seasonal changes), only the experimental class showed a statistically significant improvement, which justifies the constructivist approach. We conclude that in implementing a reform in the science curriculum, the change has to include the subjects taught and also the way they are taught. © 2006 Wiley Periodicals, Inc.

The formation of the academic counsellor     

Ricardo Blanco-Beledo 《International journal for the advancement of counseling》1982,5(4):291-299

Conclusion A detailed and exact evaluation of this program of Teacher Formation and of theactivities of academic counsellors is presently underway. We expect to have theresults by the middle of 1982. Nevertheless, partial evaluations of differentteaching and counselling activities show that there has been a change in the conceptionof what education is, development of aptitudes and attitudes and a profoundimprovement in the teaching quality.  相似文献   

Educational counselling in Mexico: Developments and perspectives     

Leticia Canales Rodriguez  Ricardo Blanco-Beledo 《International journal for the advancement of counseling》1993,16(3):205-212

Conclusion It is necessary to realize the limitations of counselling services in Mexico. In spite of all the efforts taken, the academic preparation of counsellors is not strong enough. As has been mentioned, 50% are psychologists or pedagogues, at best, and the rest, who are not specifically prepared for counselling, are constantly moving away from the helping services. There seems to be little progress. On the other hand, we hope that counselling and the counsellors, once services have been established, might some day be able to resolve those complex problems which the educational system has not been able to resolve or diminish with its own traditional resources, especially problems like school dropout, the correct choice of vocational and academic studies, the distribution of students to the various branches and levels of the educational system in accordance with the actual needs of the country, and a whole series of other tasks, which may fail in an area of myth or may really be related to the possibilities of the discipline. Therefore, it is necessary to set the limits of counsellors' tasks and to define the counsellor's role more clearly in the near future, in order to strengthen the discipline on behalf of our future students.Knowing, understanding and evaluating the relationship that now exists between the counselling tasks of counsellors, the educational Practice and the national and international policy, shall facilitate the future implementation of more solid and feasible programmes. For the time being, having a clear view of what we can do (and not only justifying things we cannot accomplish) should help our students to use our counselling services with higher benefits.  相似文献   

Performance equivalency between computer‐based and traditional pen‐and‐paper assessment: A case study in clinical anatomy          下载免费PDF全文

Bruno Guimarães  José Ribeiro  Bernardo Cruz  André Ferreira  Hélio Alves  Ricardo Cruz‐Correia  Maria Dulce Madeira  Maria Amélia Ferreira 《Anatomical sciences education》2018,11(2):124-136

The time, material, and staff‐consuming nature of anatomy's traditional pen‐and‐paper assessment system, the increase in the number of students enrolling in medical schools and the ever‐escalating workload of academic staff have made the use of computer‐based assessment (CBA) an attractive proposition. To understand the impact of such shift in the assessment method, an experimental study evaluating its effect on students’ performance was designed. Additionally, students’ opinions toward CBA were gathered. Second‐year medical students attending a Clinical Anatomy course were randomized by clusters in two groups. The pen‐and‐paper group attended two sessions, each consisting of a traditional sectional anatomy steeplechase followed by a theoretical examination, while the computer group was involved in two similar sessions conducted in a computerized environment. At the end of each of the computer sessions, students in this group filled an anonymous questionnaire. In the first session, pen‐and‐paper group students scored significantly better than computer‐group students in both the steeplechase (mean ± standard deviation: 66.00 ± 14.15% vs. 43.50 ± 19.10%; P < 0.001) and the theoretical examination (52.50 ± 12.70% vs. 39.00 ± 21.10%; P < 0.001). In the second session, no statistically significant differences were found for both the steeplechase (59.50 ± 17.30% vs. 54.50 ± 17.00%; P = 0.085) and the theoretical examination (57.50 ± 13.70% vs. 54.00 ± 14.30%; P = 0.161). Besides, an intersession improvement in students’ perceptions toward CBA was registered. These results suggest that, after a familiarization period, CBA might be a performance equivalent and student accepted alternative to clinical anatomy pen‐and‐paper theoretical and practical examinations.

Mathematics Education: A Vision of Its Evolution     

Ricardo Cantoral  Rosa M. Farfáan 《Educational Studies in Mathematics》2003,53(3):255-270

Teaching in general and teachingof mathematics in particular are matters ofgreat importance for contemporary society.Over the years, societies have establishedinstitutions in order to incorporatemathematics and science into the culture ofsociety with the clear intention ofencouraging a scientific vision of theworld among the population. This intensesocial process of scientific enlightenment has helped us recognize theneed to implement educational modificationsin the specific field of mathematics basedon designs that are better adapted toschool practices. Mathematics educationdeals with the systematic study of theeffects of such processes; in this paper,we have decided to describe a certainevolution of its research problems.

Higher education and its contribution to a diverse regional supply of human capital: does the binary/unitary divide matters?     

Artur Santoalha  Ricardo Biscaia  Pedro Teixeira 《Higher Education》2018,75(2):209-230

Diversity has been an important topic of research for some time in higher education, though the purposes underlying this attention have varied across national and regional contexts. In many parts of the world, the term diversity has been emphasized with regard to variety among the programs or services provided by academic institutions, and differences among the types of institutions themselves. It is particularly important to discuss whether different dimensions of diversity may influence the degree of effectiveness of higher education (HE) in fulfilling its contribution and relevance to economic and social development. We are particularly interested in analyzing whether unitary or binary systems present significant differences in different dimensions of diversity that may be relevant to enhance higher education institutions’ (HEIs) contribution to territorial cohesion, notably by enhancing the local stock of human capital and contributing to the social and cultural development of their regions. Therefore, we propose the following research questions: *Are there relevant patterns regarding different dimensions of diversity between unitary and binary HE systems? *In the case of binary systems, is it possible to find relevant differences in different dimensions of diversity between universities and more vocational HEIs? By looking at these questions, we aim at contributing both to the literature on HE institutional diversity and to the study of the role played by HEIs on regional development.  相似文献   

The Need for Change in Elementary‐school Teacher Training: the force concept as an example     

Ricardo Trumper 《Asia-Pacific Journal of Teacher Education》1998,26(1):7-25

Do students in preservice training programmes for elementary‐school teachers hold the correct scientific views which will eventually allow them to plan and implement instructional strategies which, in turn, will lead their future pupils to achieve a scientific concept of force? The results of a cross‐college age study dealing with this issue are discussed. The force conceptions of the students were analysed by means of a two‐part written questionnaire which was presented to them during the first week of the second semester. The most important findings of this study will be of interest to many elementary‐school teacher educators.  相似文献   

Extra-curricular participation in sports and socio-demographic factors in Spanish adolescents: the AVENA study     

Gracia-Marco L  Tomas C  Vicente-Rodriguez G  Jimenez-Pavon D  Rey-Lopez JP  Ortega FB  Lanza-Saiz R  Moreno LA 《Journal of sports sciences》2010,28(13):1383-1389

The aims of this study were to identify differences between the sexes in extra-curricular participation in sports and to determine its association with body fat and socio-demographic factors in Spanish adolescents. A total of 2165 adolescents (1124 males and 1041 females) aged 13.0-18.5 years from the AVENA Study participated. Participants filled in an ad hoc questionnaire for extra-curricular participation in sports, which was the dependent variable. Independent variables were: age, percent body fat, and father's and mother's educational level and occupation. Chi-square tests and logistic regression were applied. Bivariate analysis showed for male adolescents that age and father's occupation were related to extra-curricular participation in sports. In addition, body fat and mother's education and occupation (all P?相似文献

Teachers' Attitudes Toward Technology in a Two-Way Dual-Language Program     

Ricardo González-Carriedo  Pamela Esprívalo Harrell 《学校用计算机》2018,35(2):111-133

This study examined the attitudes of nine teachers in a two-way dual-language program in regard to using technology to support the linguistic and academic development of emergent bilinguals. Using a phenomenological, multiple case-study approach, teachers' perceptions about using technology in education and the potential of technology to advance the students' bilingualism and biliteracy were analyzed. Results showed that teachers had a positive outlook about the potential of technology as a tool to support the academic and linguistic growth of the students. However, several significant challenges were identified, most notably among them the scarcity of technological hardware at the school and the shortage of Spanish-language educational resources. The teachers' perception was that a greater availability of digital technologies, including resources in the Spanish language, would greatly enhance student learning.  相似文献
