Does regular online testing enhance student learning in the numerical sciences? Robust evidence from a large data set     

Simon D. Angus  Judith Watson 《British journal of educational technology : journal of the Council for Educational Technology》2009,40(2):255-272

While a number of studies have been conducted on the impact of online assessment and teaching methods on student learning, the field does not seem settled around the promised benefits of such approaches. It is argued that the reason for this state of affairs is that few studies have been able to control for a number of confounding factors in student performance. We report on the introduction of a regular (every 3 weeks) low-mark online assessment tool in a large, first-year business mathematics course at the University of New South Wales, a major Australian university. Using a retrospective regression methodology together with a very large and rich data set, we test the proposition that exposure to the online assessment instrument enhances student learning. Significantly, we are able to control for prior student aptitude, in-course mastery, gender and even effort via a voluntary class attendance proxy. Furthermore, the study incorporates two large, and statistically diverse cohorts as well as manipulations in the model tested to robustly examine the outcomes. Our central result is that higher exposure to the online instrument robustly leads to higher student learning, all else being equal. Various implications for online assessment design, implementation and targeting are also discussed.  相似文献   

Adolescents' and Parents' Evaluations of Helping Versus Fulfilling Personal Desires in Family Situations     

Judith G. Smetana  Marina Tasopoulos-Chan  Denise C. Gettman  Myriam Villalobos  Nicole Campione-Barr  and Aaron Metzger 《Child development》2009,80(1):280-294

A sample of 118 predominantly European American families with early and middle adolescents ( M _ages= 12.32 and 15.18 years) and 1 parent evaluated hypothetical conflicts between adolescents' and parents' requests for assistance versus the other's personal desires. Evaluations differed by level of need, but in low-need situations, adolescents viewed teens as more obligated to help parents than did parents, whereas parents rated it as more permissible for teens to satisfy personal desires than did teenagers. Justifications for helping focused on concern for others, role responsibilities, and among parents, psychological reasons. Middle adolescents reasoned about role responsibilities more and viewed satisfying personal desires as less selfish than did early adolescents, but satisfying personal desires was seen as more selfish by parents of middle than early adolescents. Implications for adolescent–parent relationships are discussed.  相似文献   

Non-accidental head injury in New Zealand: The outcome of referral to statutory authorities     

Patrick Kelly  Judith MacCormick  Rebecca Strange 《Child abuse & neglect》2009,33(6):393-401

ObjectivesTo describe the outcome of referral to the statutory authorities for infants under 2 years with non-accidental head injury (NAHI), and to establish whether the authorities held sufficient information to develop a risk profile for these cases.MethodsRetrospective review of cases admitted to hospital in Auckland, New Zealand from 1988 to 1998. Records from the hospital admission, child protective services and Police were reviewed, up to 19 years from diagnosis.ResultsOf 39 infants, 33 survived to leave hospital. Documentation of risk factors was erratic, and sometimes incongruent between agencies. Inter-agency case conferences took place in 17/39 (44%). The Department of Child, Youth and Family Services (CYF) used an informal family agreement to secure safety in 15/33 survivors (45%). Family Group Conferences occurred in 17/33 (52%). Nine of 33 were placed permanently outside the home (27%), two (6%) with unrelated caregivers. Charges were laid in 18/39 cases (46%). Fifteen cases came to trial, with 14 convictions (36%). Of the survivors, 44% were later renotified to CYF. There was no obvious relationship between type of intervention and re-notification.ConclusionsEnsuring the safety of an infant with NAHI, and identifying and taking appropriate action with regard to the offender, are complex tasks. In New Zealand, data collection is often incomplete and inter-agency practice and collaboration is variable. Although the rate of prosecution was relatively high by international standards, many children were later notified again for further concerns of abuse or neglect, suggesting that our interventions have been only partially successful.Practice implicationsThis paper suggests that all infants admitted to hospital with non-accidental head injury should become part of a prospective inter-agency research study, using a standardised data collection instrument. This should include the systematic collection of all data known or suspected to be associated with risk of child abuse, and incorporate long-term prospective follow-up, regardless of child protective or legal outcomes. Without large numbers followed prospectively and according to sound methodology, it is difficult to prove which forms of intervention are better than others at reducing the risk of further abuse.  相似文献   

Engineering an Associate Degree-Level STEM Workforce Education Curriculum     

Jason L. Selwitz  Birgitte Ahring  Manuel Garcia-Perez  Judith Morrison 《Community College Journal of Research & Practice》2018,42(6):405-421

Community and technical colleges serve a vital function in STEM education by training workers for medium- and high-skilled technical careers and providing employers the labor necessary to operate and maintain thriving business ventures. A curriculum developed with the elements of a systems-based approach results in a program more relevant to the needs of the institution, its students, and industry partners—and avoids the pitfalls of programs designed without a plan or process in place. To achieve validity and reliability, curriculum assessment tools should be conduits to collect critical feedback from students, graduates, and the industries and academic partners served. Research was undertaken to design and evaluate an associate degree-level STEM workforce education program at the nexus of bioenergy/bioproducts, electrical systems and maintenance, and wastewater treatment plant operations. Component to the research, a program’s graduates were interviewed and professionals representing a spectrum of manufacturing/processing-type industries were surveyed. A curriculum development and assessment model emerged to help community and technical college faculty and administrators develop, evaluate, and revise associate degree-level STEM workforce education programs.  相似文献   

Creating an LNG ready worker: British Columbia’s blueprint for extraction education     

Judith Walker 《Globalisation, Societies & Education》2018,16(1):78-92

Since 2011, the government of British Columbia (BC) has focused on building the Canadian province’s economy through the development of a Liquefied Natural Gas (LNG) sector. In service of this endeavour, the government launched the Skills for Jobs Blueprint, which attempts to more clearly align BC’s education system with resource extraction industries. In this paper, I argue that at the heart of this policy is the idea of education for, through, and as extraction. Conceptually, ‘extraction education’ focuses on supply (what we can take out of the earth, institutions, and individuals) rather than demand (what is needed to put into the educational system to meet needs of the land, institutions, communities, and individuals), and is problematic on environmental, economic, employment, equity, and educational fronts. In theorising ‘extraction education’ I extend Freire’s ideas on ‘banking education’ and briefly explore dialogic, problem-posing counters to it.  相似文献

An Investigative,Cooperative Learning Approach to the General Microbiology Laboratory     

Kyle Seifert  Amy Fenster  Judith A. Dilts  Louise Temple 《CBE life sciences education》2009,8(2):147-153

Investigative- and cooperative-based learning strategies have been used effectively in a variety of classrooms to enhance student learning and engagement. In the General Microbiology laboratory for juniors and seniors at James Madison University, these strategies were combined to make a semester-long, investigative, cooperative learning experience involving culture and identification of microbial isolates that the students obtained from various environments. To assess whether this strategy was successful, students were asked to complete a survey at the beginning and at the end of the semester regarding their comfort level with a variety of topics. For most of the topics queried, the students reported that their comfort had increased significantly during the semester. Furthermore, this group of students thought that the quality of this investigative lab experience was much better than that of any of their previous lab experiences.  相似文献

An Alternative Multivariate One- and Two-Sample Post Hoc Procedure     

Patricia M. Mihevic  Judith A. Spray 《Research quarterly for exercise and sport》2013,84(4):649-660

This paper illustrates the use of a Scheffé-like multivariate post hoc procedure known as the Roy-Bose or simultaneous confidence interval procedure. This method is contrasted with the use of Bonferroni or planned linear combinations for the one- and two-sample cases. The Roy-Bose procedure also is compared to the more frequently employed univariate F tests for post hoc analysis.  相似文献   

Recent Developments in Measurement and Possible Applications to the Measurement of Psychomotor Behavior     

Judith A. Spray 《Research quarterly for exercise and sport》2013,84(3):203-209

Abstract

Elementary physical education instructors and movement development clinicians frequently employ movement observation as their primary assessment strategy. The purpose of this study was to determine the minimal conditions of observation needed to obtain generalizable results across observers, trials, and subjects for the hop, jump, and run. The developmental sequences developed at Michigan State University were used as the observation system. Twelve children in the age range of 33–111 months were rated on five trials by 15 observers. The sample consisted of an equal number of males and females and did not involve children with handicapping conditions. The results suggest that when observers receive 1 hour of training for each skill, one observer and three trials are needed for evaluating the hop (.88), while three observers and three trials are required for the jump (.83). None of the nine measurement conditions resulted in acceptable (.80) generalizability for the run.  相似文献
