Simulation is the process of executing a model that describes a system with enough detail; this model has its entities, an internal state, some input and output variables and a list of processes bound to these variables. Teaching a simulation language such as general purpose simulation system (GPSS) is always a challenge, because of the way it executes the models and the abstraction level it can achieve, very different compared with most well-known programming languages. This article presents an open source simulation framework that implements a subset of entities of GPSS, which could help students to improve the understanding of this language. This tool also stores all entities of simulations in every single simulation time, which is very useful for debugging simulations, but also for getting a detailed history of all entities in the simulations, knowing exactly how they have behaved in every simulation time. 相似文献

This study focuses on the relationships between meanings of science constructed in classrooms and sociocultural precepts of the wider society. Research presented is part of a larger study of the negotiation of knowledge and roles in high school science classrooms. The data presented document that what goes on in classrooms reflects and recreates societal attitudes towards work, in general, and teachers’ work, in particular. The teacher in this study reduces his demands for academic work in return for students’ cooperation and as a means of coping with negative aspects of teaching. Students, in turn, are not concerned about the specific subject matter of chemistry. What matters to them are the academic credentials that lead to success in the college and employment arenas. As a result, teacher and students construct school chemistry to be what you‐get‐through‐as‐you‐get‐along. The interdependence of the roles and actions of teachers and students suggests changes in policy and practice. 相似文献

The aim of our study was to assess the effect of the limbs’ actions on the nonlinear properties of the four competitive swimming strokes. Forty-nine swimmers performed all-out sprints at front-crawl, backstroke, breaststroke and butterfly, each one at full stroke (FS), only the arms’ stroke (AS), and only leg kicking (LK), in a total of 12 bouts, 6 per day. A speedo-meter cable was attached to the swimmer’s hip, to collect the speed-time raw data (f = 50Hz). Velocity, speed fluctuation, sample entropy and fractal dimension were derived from the speed-time series. Significant and moderate-strong effects were noted for both stroke and condition in all variables in the study (p ≤ 0.001; 0,560<η2 < 0,952). The four competitive strokes and their three conditions exhibited nonlinear properties. The swimming pattern was less complex and more predictable for LK in comparison to AS and FS. Breaststroke and butterfly have more complex but more predictable patterns than backstroke and front-crawl. 相似文献

This article aims to shed light on the current debate regarding the role of internships in higher education in graduates’ employability. In specific, it analyses empirical data on a large-scale study of Portuguese first-cycle study programmes, in order to explore indicators of the professional value of internships in the employability of higher education graduates. Results demonstrate that study programmes that include internships tend to significantly enhance graduates’ employability, particularly within the universe of polytechnic and public higher education institutions. Besides the instrumental value of internships, the impact of the nature and structure of the internship on the percentage of unemployed graduates are also discussed. Mandatory internships and the inclusion of multiple, shorter internships throughout the degree are negatively associated with unemployment levels. Results indicate work-based learning can be used as a successful strategy to bridge theoretical knowledge and practice and enhance graduate employability. These findings provide important insights for the evaluation and/or the design of internship programmes in higher education. 相似文献

Our work is based on the study of learning strategies used by a group of trainee teachers in a real learning situation, and how this use of strategies influences the results of the learning process. We use a diary as a tool to assess the learning strategies and compare the results obtained with those using an inventory. Our findings indicate that the deliberate use of strategies (measured by diaries) has a positive effect on knowledge acquisition, with the qualitative analysis method of the verbal protocols noted in the diaries proving more valuable than the use of traditional inventories. 相似文献

Many schools are faced with the prospect of soaring absenteeism rates, despite the use of traditional truancy courts and other legal interventions. A recent trend in the literature has been to explore alternative, hybrid, and multidisciplinary approaches to address the underlying obstacles to school attendance. These programs are often integrated into schools to reduce stigma and transportation burdens on families. The present study involved an evaluation of a truancy diversion program in nine at‐risk middle schools in an ethnically diverse sample. Graduates from the program demonstrated significant declines in internalizing and externalizing behavior problems. In addition, participants and their parents expressed high levels of perceived improvement in academic performance. Academic tutoring was found to differentiate program graduates from nongraduates. Results are preliminary but discussed within the context of the role of school attachment in truancy diversion programs. 相似文献

Home shared book reading during the preschool years is a strong predictor of students’ reading achievement in primary school, and, according to Sénéchal (2012), it can benefit more children from low socioeconomic status (SES) backgrounds. This study examines the association between frequency of book reading before the start of compulsory education and the reading achievement of 4th-grade students whose parents have high and low education levels in 22 European countries. Using data from the Progress in International Reading Literacy Study (PIRLS 2011), we show that the contribution of shared reading for the achievement of students from distinct SES backgrounds is different in different countries and that shared reading does not always benefit more children from low-SES backgrounds. Results are discussed in light of Sénéchal's home literacy model, the dynamics of cultural capital, and current policy efforts to support children's literacy development in European countries. 相似文献

Researchers often use measures of the frequency of self-regulated learning (SRL; Zimmerman, American Educational Research Journal, 45(1), 166–183, 2000) processing as a predictor of learning gains. These frequency data, which are really counts of SRL processing events, are
often non-normally distributed, and the accurate analysis of these data requires the use of specialized statistical models.
In this study, we demonstrate how to implement and interpret count statistical models in path and latent profile analyses
to investigate the role of SRL as a mediator of the relation between pretest and posttest conceptual understanding. Our findings
from a sample of 170 college students using a computer to learn about the circulatory system show that SRL does mediate the
aforementioned relation, and that count models are a more accurate representation of SRL processing data than standard analysis
models based on ordinary least squares estimation. The results of our path analyses revealed which specific SRL processes
were related to learning, above and beyond the effect of prior knowledge. Our latent profile analysis revealed two groups
of participants, indicative of Brophy’s (2004) model of schematic and aschematic learners. We conclude with implications and future directions for basic and applied SRL
research. 相似文献
