This essay provides an overview of the huelga schools established in Houston, Texas, in 1970. For 2 years, from 1970 to 1972, the Mexican American community opposed the Houston Independent School District’s plan to integrate the schools by pairing so-called White Mexican Americans with African American students. While they protested this decision, Mexican Americans also established huelga or strike schools in order to provide their children with basic skills in education and to explain the meaning and significance of their political actions. This is the history of the huelga schools established in the 1st months of this struggle.  相似文献

The serial position effect in Long-Evans rats was evaluated in two experiments. In Experiment 1, the effect in a group for which an interstimulus interval (ISI) was introduced between items in a list of demonstrators was compared with that in a group without an ISI. With an ISI, a recency effect was produced. In Experiment 2, a serial position effect group was compared with four groups in which either the distinctiveness or the context of the middle item was changed, relative to the items on either side of it. A von Restorff effect was produced when a rat from a different strain was used as a demonstrator in Position 2. The results for Experiment 1 are discussed in relation to interstimulus effects in monkeys and those for Experiment 2 with respect to changes in the physical properties of middle items.  相似文献

It is well known that teachers frequently observe a decline in the scholastic motivation of many adolescent students, which in turn is often associated with a decline in students’ individual school self-concept. In contrast, less is known about the association between students’ individual school self-concept and school engagement, or the related concepts of school belonging and helplessness in school. The current study explored social relationships as mediators in the association between individual school self-concept and adolescents’ school engagement, belonging to school and helplessness in school in a large sample of 7th and 8th grade students (N?=?1088; MAge?=?13.7) in secondary schools in Brandenburg, Germany. The results of two structural equation models showed that the teacher–student relationship mediated the association between individual school self-concept and school engagement, belonging to school and helplessness in school, respectively. In contrast, the student–student relationship did not mediate any of these associations.  相似文献

Abstract

In the context of a changing society, strategies are required to eradicate the phenomenon of antisocial behaviour. The Aprender a Convivir universal prevention programme tries to provide such a response. This study attempts to test the effectiveness of the programme through a quasi-experimental long-term study carried out over three years in some nursery schools. Of the students who participated in this study (N = 784), those from the experimental group showed significant increases in social competence compared to the control group, and behavioural problems decreased, albeit not in any significant way. To draw conclusions about the effectiveness of the programme, further improvements are proposed to the design of the study.  相似文献

Culturally relevant science pedagogy is seldom discussed in terms of infusion of literary resources, such as adivinanzas and dichos in the design of instruction. In this study, the authors narrate how a science methods course was infused with the use of culturally responsive tools to purposefully connect to the elementary science curriculum. Results indicate that prospective Latino teachers found multiple opportunities to address specific science objectives with adivinanzas and expressed the advantages of using these culturally responsive tools to introduce and summarize science concepts as they implemented lessons during field experience.  相似文献

A study was conducted to quantify the effectiveness of concept maps in learning physics in engineering degrees. The following research question was posed: What was the difference in learning results from the use of concept maps to study a particular topic in an engineering course? The study design was quasi-experimental and used a post-test as a measuring instrument. The sample included 114 university students from the School of Industrial Engineering who were divided into two equivalent homogeneous groups of 57 students each. The amount of learning attained by the students in each group was compared, with the independent variable being the teaching method; the experimental group (E.G.) used concept maps, while the control group (C.G.) did not. We performed a crossover study with the two groups of students, with one group acting as the E.G. for the topic of optical fibers and as the C.G. for the topic of the fundamental particles of matter and vice versa for the other group. For each of the two topics studied, the evaluation instrument was a test of 100 dichotomous items. The resulting data were subjected to a comparative statistical analysis, which revealed a significant difference in the amount of learning attained by the E.G. students as compared with the C.G. students. The results allow us to state that for the use of concept maps, the average increment in the E.G. students’ learning was greater than 19 percentage points.  相似文献

The effects of retention and demonstration intervals on serial position were evaluated in two experiments with Long-Evans rats. A list of 3 demonstrators that had eaten one of three flavored foods was presented to naive observers. In Experiment 1, there were four groups, three groups with a retention interval compared with one group with a zero retention interval or no retention interval. In Experiment 2, the demonstration interval was reduced. Intervals of 15, 5, 2, and 1 min were used. In Experiment 1, primacy decreased gradually in the four groups as the retention interval was increased in duration. In Experiment 2, primacy also decreased gradually, and recency occurred with the 1-min demonstrator interval. The increase in the duration of the retention interval reduced primacy. The reduction in the duration of the demonstration interval decreased primacy and produced recency.  相似文献

En este artículo los autores recurren a voces de personajes chicanos para analizar y discutir la opresión lingüística del méxico americano durante las décadas de 1920 a 1960. Utilizando la teoría racial crítica y la teoría latina del racismo (CRT y LatCrit por sus siglas en inglés) los autores hacen referencia específica a pasajes, documentos históricos y piezas de la literatura para argumentar que cuestiones de poder y racismo han impactado la restricción en el uso del idioma español en los Estados Unidos. De manera específica, se hace referencia a los castigos sufrido por varias generaciones de hispanoparlantes.

In this article, the authors analyze and discuss the linguistic oppression faced by Mexican-Americans from the 1920s to the 1960s as narrated by Chicano voices. Critical Race Theory and Latino/a Critical Race Theory permeate the argument that issues of power and racism have impacted the use of Spanish in the United States. This oppression is reflected in historical documents, passages, and segments of Chicano literature. Specifically, the article describes instances of punishment suffered by several generations of Spanish speakers.  相似文献
