Writing is a task that entails high cognitive and linguistic efforts, especially when producing academic texts. Academic language might be one of the factors influencing the quality of written texts, given that prior research has shown its impact on reading comprehension. The purpose of this study is to examine the contribution of Spanish Core Academic Language Skills (S-CALS) and academic vocabulary to the quality of written argumentation and explanation. For this study, 126 Chilean 8th grade students produced an argumentative text and an explanatory text about the same topic. In addition, their academic vocabulary was assessed with the S-AVoc-T test and their CALS with the S-CALS-I test. Results show that both CALS and academic vocabulary are significantly and positively correlated with both writing tasks. Even though these instruments make different contributions to the predictive models in each discursive genre, a Principal Component Analysis revealed that the model that best explains writing quality are those which combine both language variables, namely Spanish Core Academic Language and Vocabulary Skills (S-CALVS). In argumentation, the S-CALVS model explains 29% of the variance, after controlling by gender. In contrast, in explanation, S-CALVS explains 35% of the variance. It is concluded that it is relevant to develop situated writing in each discursive genre and, upon that basis, to work with both CALS and academic vocabulary, because they have a specific impact on academic texts writing. 相似文献

ResumenEl presente informe analiza la expresión emocional de los ciegos congénitos mediante una codificación muscular de los movimientos faciales. Esta expresión, de carácter más involuntario, es semejante a la de los videntes. En cambio, los sujetos invidentes tienen una expresividad menor y menos diferenciada en las poses voluntarias. Los resultados, que confirman los hallazgos de autores anteriores, apoyan la existencia de dos fuentes de información en el desarrollo emocional: una de naturaleza genética, que explicaría las semejanzas en la expresión emocional o involuntaria, y otra ambiental, que daría cuenta de las diferencias en la expresión voluntaria. Por último, se plantean las consecuencias de este trabajo para las distintas disciplinas psicológicas. 相似文献

This paper describes the experience of an introductory discipline to the engineering curricula at the Brazilian Federal University of ABC (UFABC). The university offers a common basic curriculum that must be accomplished by every student and can be followed by professionalising courses. The discipline ‘Introduction to Engineering’ presents the basis of the engineering career, methods and thinking together with professional commitments and regulations. The objective is to help students to consciously choose their careers, minimising the precocity problem in deciding a professional future. The discipline methodology includes activities proposed by the TryEngineering website and from Brazilian engineering councils. Lectures with invited professors introduce UFABC engineering specialities: Aerospace, Bioengineering, Energy, Environmental & Urban, Information, Instrumentation & Automation & Robotics, Management, Materials. This paper reports the proposed activities, results obtained by the students, a methodology critical analysis and the impacts on the following steps of students embracing an engineering career. 相似文献

The paper deals with physics teaching/learning in high school. An investigation in three upper secondary school classes in Italy explored the reactions of students to a structuring lecture on optics within the discipline-culture (DC) framework that organises physics knowledge around four interrelated fundamental theories of light. The lecture presented optics as an unfolding conceptual discourse of physicists regarding the nature of light. Along with the knowledge constructed in a school course of a scientific lyceum, the students provided epistemological comments, displaying their perception of physics knowledge presented in the classroom. Students’ views and knowledge were investigated by questionnaires prior to and after the lecture and in special discussions held in each class. They revealed a variety of attitudes and views which allowed inferences about the potential of the DC framework in an educational context. The findings and interpretation indicate the positive and stimulating impact of the lecture and the way in which DC-based approach to knowledge organization makes physics at school cultural and attractive. 相似文献

ABSTRACTEarly Augmentative and Alternative Communication (AAC) interventions in school environments aim to support the development of the communication skills of children with complex communication needs. Goals of this study were to analyse the teachers’ attitudes towards children using AAC in primary schools in Italy and their perceptions of the barriers and the benefits of using AAC. Two groups of teachers, those with and without AAC experience, responded to an online survey. The five scales of the Teacher Attitude Scale (TAS) questionnaire and two open-ended questions were used to compare the attitudes and the perceptions between the groups of teachers. Results showed that there was a significant difference among the two groups for two of the five scales of the TAS questionnaire. Both groups reported similar barriers and benefits and indicated the use of AAC as being the main barrier. In conclusion, having experience with children who use AAC in class impacts the teachers’ perceptions of their own abilities and the teachers’ perceptions of the abilities of the children. 相似文献

Wild botanic gardens consist of natural or semi-natural land remnants immersed in large urban areas or botanic gardens, which are managed for purposes of biodiversity preservation and public recreation. In Latin America, they tend to be affected by budget limitations; however, they serve as valuable resources that permit the development of innovative environmental education programmes. Specifically, we are considering the appropriateness of implementing critical environmental education and socio-constructivist programmes. As for practical considerations, it is important to include diverse epistemologies, and therefore, strategies or procedures characteristic of science teaching, such as problem-based learning, together with other characteristics of social activism and popular education initiatives, such as assemblies or meetings, and others characteristic of more traditional and indigenous worldviews, such as celebrations of the earth. In this way, Latin American wild botanic gardens may play a role in constructing environmentally responsible societies and the nurturing of a culture of reflective inquiry. 相似文献

Eye gaze is an important communicative signal, both as mutual eye contact and as referential gaze to objects. To examine whether attention to speech versus nonspeech stimuli in 4- to 5-month-olds (n=15) varies as a function of eye gaze, event-related brain potentials were used. Faces with mutual or averted gaze were presented in combination with forward- or backward-spoken words. Infants rapidly processed gaze and spoken words in combination. A late Slow Wave suggests an interaction of the 2 factors, separating backward-spoken word+direct gaze from all other conditions. An additional experiment (n=15) extended the results to referential gaze. The current findings suggest that interactions between visual and auditory cues are present early in infancy. 相似文献
