Despite research having highlighted the positive outcomes of the use of videogames to learn, their integration into school contexts remains rare. Literature recognizes the importance of user’s technology acceptance to predict the intention to use and the adoption of new technology in several settings. So far, investigations have primarily focused on students’ and teachers’ opinions, while only a few studies have considered the role of parents. This study aimed to investigate the role of the dimensions of the technology acceptance model on parental preference (254 Italian parents) for the adoption of videogames in primary or secondary schools. Results revealed that 71% of the variance of parental acceptance of videogames is explained by perceived usefulness, perceived ease of use, learning opportunities, and parental game expertise. Initiatives aimed to increase parental understanding of videogames as educational tools are encouraged.  相似文献

RESUMEN

El punto de partida del trabajo presentado en el estudio de las variedades no standard del francés. Tras la constatación de que el marco de referencia utilizado hasta ahora para el estudio de estas variedades ha sido fundamentalmente la variedad standard escrita, los autores proponen un cambio de óptica al abordar la descripción y análisis del lenguaje oral de locutores adultos y niños en diferentes tipos de situaciones informales. Ello les lleva a reconocer dentro de la competencia lingüística de los locutores un doble sistema de organización de los enunciados: el basado en el modelo tradicional de la frase o construcción gramatical y el basado en las configuraciones discursivas.

Tras pasar revista a ambos tipos de sistemas y proporcionar una serie de ejemplos de configuraciones discursivas complejas, los autores abordan desde esta perspectiva un análisis somero de las relaciones existentes entre sistema lingüístico y otros componentes que determinan las producciones verbales de los locutores. Finalmente, el nuevo marco de referencia adoptado les lleva a replantearse la relación entre la variedad standard normativa y las restantes variedades no standard, así como a una revisión de las diferencias constatadas entre las producciones lingüísticas de los niños y las de los adultos.  相似文献

Resumen

El artículo revisa las relaciones entre, por una parte, la psicología de la educación y de la instrucción y, por otra, las didácticas específicas. Partiendo de las representaciones que didactas y psicólogos tienen de sus respectivos campos de trabajo, se constata la existencia de un «espacio de problemas» común en torno a los procesos escolares de enseñanza y aprendizaje y, al mismo tiempo, una aproximación netamente diferenciada a dichos problemas. Sin embargo, la aparición en el transcurso de las dos últimas décadas de una serie de tendencias y movimientos que se manifiestan por igual en el ámbito de la psicología y de las didácticas apunta, de forma inequívoca, a una mayor interconexión e interrela- ción entre ambas aproximaciones disciplinares.  相似文献

Service-learning is an approach to teaching and learning that has great potential for gerontology. The articles in this special issue present a wealth of conceptual and practical information about how to create service-learning opportunities, manage them effectively, and evaluate them appropriately. This article identifies several common themes in the articles and offers an administrative perspective on the role and value of service-learning.  相似文献

Using graduate social work students' data (n = 481) in the Hartford Partnership Program for Aging Education (HPPAE) in the United States, the study examined psychometric properties of the Knowledge of Aging for Social Work Quiz (KASW), a revision of the Facts on Aging Quiz, to evaluate biopsychosocial knowledge relevant to social work. We examined the intercorrelations of the KASW with the academic and practice experience in aging and score differences by the specialization and school year, and estimated the internal consistencies as reliability. Results showed the convergent validity of the KASW, indicating the items measured theoretically related areas of content with students' skills and experiences in aging. The internal consistencies, nevertheless, remained relatively low, representing the items that failed to measure the expected constructs of biopsychosocial domains. The KASW will be further refined to more sensitively identify students' knowledge deficiencies by selecting an optimal panel of items in biopsychosocial content areas and by providing information relevant to the pedagogical agenda and guidance in field education.  相似文献

In this study, we examined relationships between the use of test results and US students’ math, reading, and science performance in the Programme for International Student Assessment (PISA) 2009. Based on a literature review, we hypothesized that the 16 items in the PISA school questionnaire, which are related to the use of test results, can be categorized according to 4 factors. We validated this hypothesized factor structure using a confirmatory factor analysis and then obtained composite scores for each factor. As revealed by a multilevel analysis, when student and school demographic variables were controlled for, using test results to hold schools accountable to authority and the public was significantly positively related to students’ performance across all 3 subjects. No statistically significant relationship, however, was detected between students’ performance and the following uses of test scores: informing parents of their children’s performance, providing information for instructional purposes, and evaluating teachers and principals.  相似文献

ABSTRACT

This study investigated how studying a refutational map, a type of argument map, affected conceptual change. Refutational maps visually display both correct and alternative conceptions. Participants (N?=?120) were randomly assigned to (1) a refutational map condition, (2) a refutational text condition, and (3) a non-refutational text condition. The post-test results showed that studying the refutational map led to better performance on free recall and learning transfer measures. Specifically, participants who studied the refutational map performed significantly better than others on a free recall test, and they significantly outperformed the non-refutational text group on a short-answer transfer test. The multiple-choice test, another transfer measure, failed to detect any differences among the three groups. The research also found that individual differences in need for cognition and logical thinking ability interacted with the type of study materials. Participants scoring lower on logical thinking ability gained more from studying the refutational map.  相似文献

Vowel representations are particularly difficult for children to learn because most vowel phonemes can be spelled in several different ways. Children in Grades 1, 2, and 3 spelled nonwords with an ambiguous vowel and reported their spelling strategies. Analysis of the children's spellings and strategy reports revealed a shift in relying solely on phonological information to considering orthographic information for making vowel letter choices. Implications for vowel spelling development are discussed.  相似文献
