Cupi2 is a project that promotes an integral solution to problems in teaching/learning programming using a large and structured courseware, and a student-centered pedagogical model (Villalobos and Casallas 2006a; Villalobos et al. 2009a, b; Jiménez and Villalobos 2010). As a cornerstone of Cupi2, we use incremental projects intended to motivate students, and to develop high-level programming skills throughout their learning. A critical factor of these projects is that they are specially designed so that students are engaged in activities that complete a scaffold of a complete program. However, both the scaffolds and the activities needed to complete these incomplete programs must be arranged carefully by instructors in order to stress the adequate contents for students, and at the same time, to help those students acquire programming skills effectively. Jointly, scaffold versions need to comply with high quality standards, representing a high time consuming activity for instructors, and therefore, increased costs for institutions. In this paper, we describe the way we overcome these challenges using a software factory that supports the projects’ design in a scalable way. 相似文献

Technology is modifying the way companies do business all over the world. The education sector is no exception; virtual education has emerged as a basic tool to satisfy the changing needs of traditional and newly incorporated students, as well as meet the new requirements of educational institutions. This article therefore tries to achieve a double objective: to analyze what drives the development of online education within the Universities of the European Union and to design a theoretical framework that permits to obtain responses to que question of why students continue their estudies at the same educational institution. Thus, first, the analysis of external factors identifies social, political and technological capacity as issues that explain the rise of e-learning within the field of European higher education. Second, the empirical work shows the design of a cause-effect model with relationships between different variables in which market orientation of Universities and usability play an important role in the future intentions of use for students. 相似文献

ABSTRACTPrevious research on remediation has examined course placement practices, but little is known about first responders and how their beliefs about proper course placements help maintain patterns in course access. This study examined how taken-for-granted racial beliefs were used as legitimate knowledge by community college counselors. Haney López’s (2000) race as commonsense theoretical perspective was used to analyze interview data from 34 counselors in 2 southern California community colleges. Data showed that counselors recreated race categories and racial hierarchy, and they did so by reinforcing beliefs about white students as intelligent and deserving higher placements and Latina/o students as comparatively lower in ability and deserving remediation. The results suggest that counselors begin institutionalizing racial sorting immediately as first-time students begin to enroll. The findings highlight the importance of racial mindfulness in policy, practice, and research. 相似文献

This paper compares the efficiency of calculus classes. Two kinds of classes are evaluated: the traditional ones and others that use computational methods in teaching. This experiment was performed at Fluminense Federal University, Niterói, Brazil, from 1998 to 2000. The emphasis of this paper is on the quantitative evaluation using two operational research tools: multicriteria decision aid methods (mainly using the MACBETH approach) and data envelopment analysis. The evaluating variables are the level at which students enter the university and the performance of the students after studying calculus. 相似文献

In a randomised controlled trial design, effects of 6 weeks of plyometric training on maximal-intensity exercise and endurance performance were compared in male and female soccer players. Young (age 21.1 ± 2.7 years) players with similar training load and competitive background were assigned to training (women, n = 19; men, n = 21) and control (women, n = 19; men, n = 21) groups. Players were evaluated for lower- and upper-body maximal-intensity exercise, 30 m sprint, change of direction speed and endurance performance before and after 6 weeks of training. After intervention, the control groups did not change, whereas both training groups improved jumps (effect size (ES) = 0.35–1.76), throwing (ES = 0.62–0.78), sprint (ES = 0.86–1.44), change of direction speed (ES = 0.46–0.85) and endurance performance (ES = 0.42–0.62). There were no differences in performance improvements between the plyometric training groups. Both plyometric groups improved more in all performance tests than the controls. The results suggest that adaptations to plyometric training do not differ between men and women. 相似文献

This commentary is a critical appraisal of Gil-Pérez et al.'s (2002) conceptualization of constructivism. It is argued that the following aspects of their presentation are problematic: (a) Although the role of controversy is recognized, the authors implicitly subscribe to a Kuhnian perspective of `normal' science; (b) Authors fail to recognize the importance of von Glasersfeld's contribution to the understanding of constructivism in science education; (c) The fact that it is not possible to implement a constructivist pedagogy without a constructivist epistemology has been ignored; and (d) Failure to recognize that the metaphor of the `student as a developing scientist' facilitates teaching strategies as students are confronted with alternative/rival/conflicting ideas. Finally, we have shown that constructivism in science education is going through a process of continual critical appraisals. 相似文献

This study investigated the similarity of information provided from a daily behavior report card (DBRC) as rated by the teacher to direct observation data obtained from external observers. In addition, the similarity of ratings was compared with variations of problem severity (mild, severe) and teacher training (none, some). Results suggested a moderate association between teacher perceptions of behavior as measured by DBRC ratings and direct observation conducted by an external observer. In addition, 23–45% of the variance in DBRC ratings was consistent with the direct observation data. Severity of the behavior problem or the inclusion of training was not found to significantly affect the similarity of ratings. In summary, results tentatively suggest that the DBRC may be a viable supplement to direct observation for estimating behavior in applied settings. Limitations, future research directions, and implications are discussed. © 2005 Wiley Periodicals, Inc. Psychol Schs 42: 669–676, 2005. 相似文献

When translating word problems into equations, a common error consists of using the same letter to refer to two different quantities. This error, called multiple referents for the unknown, can be connected to the existence of deictic or indexical expressions within the problem statement. This paper aims to analyse the influence of indexical expressions on the incidence of the multiple referents for the unknown error. Results from a quantitative study with 117 Spanish secondary students show a significantly higher number of such type of error when the problem statement contains indexical expressions. The analysis of students’ performances in subsequent interviews indicates that this error may be due to the fragmented reading of statements. 相似文献

We conducted a qualitative study in four countries of the Europe and Central Asia (ECA) region and explored the Early Childhood Education (ECE) policy landscape with an emphasis on the challenges and opportunities decentralization has presented for the provision of services. We content-analyzed ECE policies and documents to map national approaches to ECE. Key informant interviews were conducted to assess the implementation of decentralized ECE governance. An analytical framework that combined core constructs of ECE systems and key domains of decentralization (autonomy, institutional capacity and accountability) was developed and applied. Our analysis points to four overarching processes that contribute to the perpetuation and possible increase of inequitable ECE including (1) sparse mechanisms for participatory and autonomous policy formulation, with few systematic efforts to strengthen local institutional capacities; (2) fragmented policy approaches to promote the assessment and strengthening of quality at scale; (3) funding frameworks and financing schemes that tend to benefit enrolment in contexts of higher levels of economic development; and (4) few mechanisms for coordination to ensure operational coherence across the ECE sector. 相似文献

Progress in the development of an intensive time-series design for use in classroom situations has raised several questions regarding the validity of the data obtained. One such question is related to the effect of frequency of testing upon the data. This study was designed to determine the presence of such an effect. Use of the design with eighth grade students studying a unit on crustal evolution indicated that the frequency of data collection did not adversely affect student attitudes toward the science class nor did it have any measurable effect upon class achievement data. The results of a previous study were also replicated, giving increased confidence in the validity of the data yielded by the intensive time-series design as used in these studies. 相似文献
