The effects of using graphing calculators to enhance college students' performance in precalculus     

Antonio R. Quesada  Mary E. Maxwell 《Educational Studies in Mathematics》1994,27(2):205-215

This study extended through three academic semesters and involved 710 subjects. It compared the performance of college students taught precalculus using a graphing calculator and a textbook written to be used with a graphing utility, to the performance of students using the traditional approach, a regular textbook, and a scientific calculator. On a comprehensive common final exam, students who were taught precalculus using the graphing calculator had significantly higher scores than those taught by traditional methods.PosthumousPreliminary partial results of this experiment were presented at the Fourth Annual International Conference on Technology in Collegiate Mathematics, Portland, Oregon, November 15–17,1991.  相似文献

Processes Involving Perceived Instructional Support,Task Value,and Engagement in Graduate Education     

Gwen C. Marchand  Antonio P. Gutierrez 《Journal of Experimental Education》2017,85(1):87-106

The purpose of this study was to investigate the relations among perceived instructional support (provision of relevance and involvement), subjective task value beliefs (utility, attainment, and intrinsic value), and engagement (behavioral and emotional) over the course of a semester for graduate students enrolled in an introductory research methods course in a college of education (N = 217). Structural equation modeling (SEM) results suggested that each source of perceived support exerted unique influence on students' beliefs about utility value, intrinsic value, and attainment value of their research methods coursework. In turn, midsemester value beliefs predicted semester-end student reports of behavioral and cognitive engagement. Direct and indirect effects between perceived provisions of support and engagement were inconsistent. This study supports the notion that different patterns of predictors and outcomes may occur for different aspects of value beliefs and that multiple sources of instructional support are important for supporting student motivation for adult learners.  相似文献

``Weighing' the Earth: a Newtonian Test and the Origin of an Anachronism     

Moreno Gonzáalez  Antonio 《Science & Education》2001,10(6):515-543

The measure G, the universal gravitational constant, is attributed to Henry Cavendish. Nevertheless, the intention of the English physicist was to measure the density of the earth, which at that time was necessary in order to decide between different theories about the composition of this planet. G was measured much later. In this article I will try to explain how Cavendish accomplished the famous experiment and what his results were. Likewise, I will consider the problems that can arise in the scientific training of students from maintaining anachronisms such as this.  相似文献   

An assessment of the sources of the reversal error through classic and new variables     

Carlos Soneira  José Antonio González-Calero  David Arnau 《Educational Studies in Mathematics》2018,99(1):43-56

We present two empirical studies with 241 and 211 pre-service teachers that evaluate the explanatory power of word order matching and static comparison as models for the reversal error. We used tasks consisting of generating an algebraic equation representing a comparison given in a verbal statement. We introduce the types of magnitude involved in the statement as variables of analysis, something that was not previously tackled in previous works. Our results show that there are no statistical differences in the production of reversal errors depending on the information included in the name used to designate the variable, and that there are statistical differences depending on the syntactic configuration as well as the type of magnitude involved in the statement. The interpretation of these results indicates that both word order matching and static comparison have some potential as explanatory models for the reversal error, and that neither one of them, alone, is enough to completely explain the phenomenon.  相似文献   

水平支座上独立式刚性块的摆动模型（英文）     

Antonio GESUALDO  Antonino IANNUZZO  Michela MONACO  Francesco PENTA 《浙江大学学报(A卷英文版)》2018,(5)

目的:本研究集中探讨水平支座上独立放置简单叠合的双刚性块的动力学行为,旨在通过构建并求解合适的动力学数值模型以助于设计可广泛适用于博物馆、实验室和医院的保护小型艺术品或装置的隔振系统。创新点:1.研究对象为两个叠合在一起的刚性块,较以往同类问题中的单一刚性块,更具现实意义;2.同时研究了刚性块的摆动和滑动两类运动模式。方法:1.基于达朗贝尔原理构建摆动控制方程,分析单刚体情形下的摆动并利用数值手段描述其滑动状态;2.在分析单刚体的基础上构建双刚体控制方程组并对其进行数值求解。结论:1.通过研究大理石雕塑置于蹲式刚性基底上且基底独立放置在移动地面上的情形发现,相比于滑动,雕塑自身的摆动是造成其损坏的主要原因;2.在某些情况下,刚体表面延迟的存在可以避免细长刚性块的翻转,尤其是对于那些细长的摇摆块体以及上部块体质量增加的情形;3.本文提出的数值分析可以成为优化简易隔振系统的一个有效工具。  相似文献   

Experiences in education innovation: developing tools in support of active learning     

Carlos Vera  Jesús Félez  José Antonio Cobos  María Jesús Sánchez-Naranjo 《European Journal of Engineering Education》2006,31(2):227-236

The paper focuses on educational projects developed in the ETSII (Escuela Técnica Superior de Ingenieros Industriales) of the Polytechnic University of Madrid during the past few years. These projects were developed as new tools for enhancing the active role of students, for improving practical teaching, especially by means of virtual laboratories and different sets of problems and exercises, and for promoting self-learning. The paper analyses the use of ICT in teaching, with the case of a developed e-learning platform as a tracking system for subjects. The paper concludes by discussing the new educational trends in the Centre, devoted to develop an active role of students by activities such as peer mentoring and laboratory monitors programs, and competitions for achieving multidisciplinary engineering challenges.  相似文献

Is device-measured vigorous physical activity associated with health-related outcomes in children and adolescents? A systematic review and meta-analysis     

Antonio García-Hermoso  Yasmin Ezzatvar  Robinson Ramírez-Vlez  Jordi Olloquequi  Mikel Izquierdo 《运动与健康科学(英文)》2021,10(3):296

ObjectiveThis study sought to analyze the prospective association between vigorous-intensity physical activity (VPA) and health-related outcomes in children and adolescents.MethodsStudies reporting associations between device-measured VPA and health-related factors in children and adolescents aged 3–18 years were identified through database searches (MEDLINE, EMBASE, and SPORTDiscus). Correlation coefficients were pooled if outcomes were reported by at least 3 studies, using DerSimonian-Laird random effects models.ResultsData from 23 studies including 13,674 participants were pooled using random effects models. Significant associations were found between VPA at baseline and overall adiposity (r = −0.09, 95% confidence interval (95%CI): –0.15 to –0.03; p = 0.002; I² = 89.8%), cardiometabolic risk score (r = –0.13, 95%CI: –0.24 to –0.02, p = 0.020; I² = 69.6%), cardiorespiratory fitness (r = 0.25, 95%CI: 0.15−0.35; p < 0.001; I² = 57.2%), and total body bone mineral density (r = 0.16, 95%CI: 0.06 to 0.25; p = 0.001; I² = 0%).ConclusionVPA seems to be negatively related to adiposity and cardiometabolic risk score and positively related to cardiorespiratory fitness and total body bone mineral density among children and adolescents at follow-up. Therefore, our findings support the need to strengthen physical activity recommendations regarding VPA due to its health benefits in children and adolescents.  相似文献
