Abstract

In this experimental study, we examined the effects of a technology-mediated intervention to improve students’ understanding of academic vocabulary and its impact on measures of vocabulary and comprehension. The Vocabulators program was implemented in two states involving 24 teachers and 200 third-grade students identified as in need of supplemental vocabulary instruction. Individual students within each classroom were randomly assigned to treatment (n?=?100) or typical instructional practices (n?=?100) conditions. In the treatment condition, students received, on average, 29 lessons on vocabulary and comprehension. Results of linear regression analyses showed statistically significant and practical effects on experimenter-developed proximal measures of decoding (ES = 0.52), expressive vocabulary (ES = 0.78), receptive vocabulary (ES = 0.51), and near transfer measures of understanding vocabulary in sentences (ES = 0.65), and informational text comprehension (ES = 0.28). Group performance did not differ statistically on near transfer measures of sentence verification with vocabulary and narrative text comprehension as well as distal standardized measures of general vocabulary or reading comprehension. Findings suggest the potential impact of technology-based vocabulary/comprehension lessons to supplement typical instruction.  相似文献

Teachers’ confidence in their ability to perform the actions that lead to student learning is one of the few individual characteristics that predicts teacher practice and student outcomes. Teachers and especially student teachers need strong efficacy beliefs in order to continue teaching during in‐service education. The current study explores the factors that precede student teachers’ beliefs of teaching efficacy and determine their conviction that they can influence instructional strategies, classroom management, and students’ engagement. In the study 198 fourth‐year students from two primary education departments in Greece completed a Teacher Efficacy Sources Inventory and a Teachers’ Sense of Efficacy Scale. It was found that self‐perceptions of teaching competence, personal characteristics, and motivation for teaching were contributory factors to teaching efficacy. The search for this type of information from student teachers is based on the assumption that feedback from students comprises a substantive factor in relation to the evaluation and improvement of teacher training programmes.  相似文献

Previous research has extensively evaluated the impact of delay on the value of positive reinforcers, but the study of its impact on the value of aversive consequences is scarce. The present study employed a modification of Evenden and Ryan’s procedure (1996, Psychopharmacology, 128(2), 161–170) to obtain data on temporal discounting of an aversive consequence, with rats as experimental subjects. In the first phase of the procedure, rats chose between one-pellet and four-pellet alternatives; when subjects developed preference for the larger-amount alternative, a shock was added to it, resulting in a loss of preference. In the first experimental condition, the delay to shock was progressively increased within each session from zero to 40 s (ascending delays), which resulted in a recovery of the preference for the larger-amount + shock alternative as the delay to shock was increased. In a subsequent condition (descending delays) the delay to shock was progressively decreased within each session, from 40 to 0 s. In both conditions, the preference for the smaller-amount no-shock alternative was well described by a hyperbolic function. The order of presentation of the delays within the session, ascending or descending, did not alter the relationship between preference and delay to shock. The temporal discounting curve obtained in the present study could represent a baseline for analyzing the impact that diverse environmental and pharmacological variables have on the temporal discounting of aversive consequences.  相似文献

Visualizing anatomical structures and functional processes in three dimensions (3D) are important skills for medical students. However, contemplating 3D structures mentally and interpreting biomedical images can be challenging. This study examines the impact of a new pedagogical approach to teaching neuroanatomy, specifically how building a 3D‐model from oil‐based modeling clay affects learners’ understanding of periventricular structures of the brain among undergraduate medical students in Colombia. Students were provided with an instructional video before building the models of the structures, and thereafter took a computer‐based quiz. They then brought their clay models to class where they answered questions about the structures via interactive response cards. Their knowledge of periventricular structures was assessed with a paper‐based quiz. Afterward, a focus group was conducted and a survey was distributed to understand students’ perceptions of the activity, as well as the impact of the intervention on their understanding of anatomical structures in 3D. Quiz scores of students that constructed the models were significantly higher than those taught the material in a more traditional manner (P < 0.05). Moreover, the modeling activity reduced time spent studying the topic and increased understanding of spatial relationships between structures in the brain. The results demonstrated a significant difference between genders in their self‐perception of their ability to contemplate and rotate structures mentally (P < 0.05). The study demonstrated that the construction of 3D clay models in combination with autonomous learning activities was a valuable and efficient learning tool in the anatomy course, and that additional models could be designed to promote deeper learning of other neuroanatomy topics.

Bidirectional relations among adolescents’ positivity, perceived positive school climate, and prosocial behavior were examined in Colombian youth. Also, the role of a positive school climate in mediating the relation of positivity to prosocial behaviors was tested. Adolescents (= 151; Mage of child in Wave 1 = 12.68, SD = 1.06; 58.9% male) and their parents (= 127) provided data in two waves (9 months apart). A model of bidirectional relations between positivity and perceived positive school climate emerged. In addition, adolescents with higher levels of perceived positive school climate at age 12 showed higher levels of prosocial behaviors in the following year. Positive school climate related positivity to adolescents’ prosocial behavior over time.  相似文献

The paper investigates the views of Greek university graduates on the link between higher education and productivity in order to determine the extent to which productivity can be considered to be an indication of quality in higher education. It also investigates the perceived effect of the type and content of higher education on productivity; factors limiting the positive impact of higher education on productivity; and ways of reducing the influence of these factors. In-depth interviews were conducted with 40 employed university graduates in Greece. Respondents generally considered higher education to have a productivity-enhancing effect, in disagreement with the screening challenge to the human capital interpretation of the link between education and productivity. The findings also suggest that respondents embraced specific conceptualisations of quality in higher education.  相似文献

The reduced budgetary appropriations that have been allocated to higher education are reflected in the management of the Portuguese university libraries. The organization of the libraries of the University of Lisbon is described, and certain deficiencies common to them and to the other Portuguese university libraries are pointed out, such as the lack of adequately trained professional staff members. Reference is made to the current state of computerization of the catalogues of collections and to the problems which have arisen as a result of the need to standardize procedures with regard to participation in the National Bibliographic Database ‐‐ PORBASE. The role of university libraries in their su rounding communities is stressed as well as the urgent need to find ways of overcoming the crisis situation which characterizes the European university libraries.  相似文献

ABSTRACT

This paper explores the attitudes of secondary-school head teachers towards religious diversity, intercultural and interreligious dialogue and the role of education in fostering intercultural and interreligious dialogue. A sample comprising 275 head teachers in Catalan secondary schools answered an online questionnaire. The results revealed attitudes which were moderately favourable towards cultural and religious diversity, more strongly favourable towards interreligious dialogue, and less favourable towards education playing a major role in managing religious and cultural diversity and in fostering interreligious dialogue. We found significant differences in head teachers’ attitudes in line with the specific features of the schools where they worked. Amongst these differences, it was noticeable that heads of religious and private–public schools had more positive attitudes towards managing religious and cultural diversity and towards education playing a leading role in promoting dialogue. Also, we identified three groups of head teachers who showed differing degrees of positivity according to the perceived religious diversity of their schools. The more diverse the school, the less favourable the attitude, and vice-versa; the most moderate favourability was also associated with the most moderate diversity.  相似文献

ABSTRACT

Deep reading comprehension refers to the process required to succeed at tasks defined by the Common Core State Literacy Standards, as well as to achieve proficiency on the more challenging reading tasks in the Program for International Student Assessment (PISA) framework. The purpose of this study was to test the hypothesis that three skill domains not frequently attended to in instruction or in theories of reading comprehension—academic language, perspective taking, and complex reasoning—predict outcomes on an assessment of deep reading comprehension. The Global Integrated Scenario-based Assessment (GISA; O'Reilly, Weeks, Sabatini, Halderman, & Steinberg, 2014 O'Reilly T., Weeks, J., Sabatini, J., Halderman, L., & Steinberg, J. (2014). Designing reading comprehension assessments for reading interventions: How a theoretically motivated assessment can serve as an outcome measure. Educational Psychology Review, 26, 403424. doi:10.1007/s10648-014-9269-z[Crossref], [Web of Science ®] [Google Scholar]) is designed to reflect students' abilities to evaluate texts, integrate information from an array of texts, and use textual evidence to formulate a position, all features of deep reading comprehension. We tested the role of academic language, perspective taking, and complex reasoning in explaining variance in end-of-year GISA scores, controlling for beginning-of-year scores and student demographics. All three predictors explained small, but significant, amounts of additional variance. We suggest that these three skill domains deserve greater attention in theories of reading comprehension and in instruction.  相似文献
