Using a computer-aided personalized system of instruction to enhance the mastery of statistics in online learning     

Robert C. Butler  Christopher D. Blair  Rae Ette Newman  Leah L Batchelor 《Teaching Statistics》2023,45(3):148-157

This study compared the effectiveness of teaching a distance education statistics course using a computer-aided personalized system of instruction (CAPSI) in comparison to a distance education course that used video lectures. Data were collected between 2017 and 2022. Two-hundred and sixty-eight students were included in the sample. Results supported that students enrolled in the CAPSI statistics course were less likely to drop out of the course and mastered significantly more material than students enrolled in the lecture-based distance education course. It is recommended that instructors teaching statistics in distance education settings consider using CAPSI to improve student outcomes.  相似文献   

No place to call home: Cultural homelessness, self-esteem and cross-cultural identities     

Raquel C. HoerstingSharon Rae Jenkins 《Int J Intercult Relat》2011,35(1):17-30

This study examined relations between a cross-cultural geographically mobile childhood and adulthood cultural homelessness, attachment to cross-cultural identities, and self esteem. Cross-cultural identities are loosely defined identities (e.g., third culture kids, military brats, missionary kids) that describe some individuals’ childhood cross-cultural experience. The 475 participants spent at least two years before age 18 in a country different from their parents’ home culture, then returned to the latter. They completed an online survey which included general demographic information regarding cross-cultural experiences in childhood, as well as the Cultural Homelessness Criteria, the Rosenberg Self Esteem Scale, and items that evaluated the strength of affirmation, belonging, and commitment to a self-labeled cross-cultural identity. Cultural homelessness was related to lower self esteem scores; higher affirmation, belonging and commitment to any cross-cultural identity was related to higher self esteem and lower cultural homelessness. Furthermore, such affirmation, belonging, and commitment buffered the cultural homelessness-self esteem association, whereas just having a cross-cultural identity did not.  相似文献   

Rural women in development: Veil of invisibility,world of workFemmes rurales et le developpement: Voile d'invisibilite,monde de travailLas mujeres rurales en el desarrolo: El velo de las invisibilidad,en mundo del trabajo     

Rae Lesser Blumberg 《Int J Intercult Relat》1979,3(4):447-472

Over the last decade, evidence has been accumulating that the process of development has resulted more frequently in greater economic marginalization than benefits for poor rural women in much of the Third World. Yet recent efforts aimed at incorporating these poor non-urban women into development have been hampered by the “veil of invisibility” hiding their past and present conditions and contributions. This article formulates some hypotheses concerning female invisibility as well as productivity, and then contrasts the extant view of rural Third World women as relatively unproductive with (1) evidence drawn from evolutionary history, and (2) data from new micro-level and UN studies. The former indicates that women were the primary producers in most pre-agrarian human groups. The latter indicate that women continue to produce approximately half the world's food, although there is dramatic regional variation. The article concludes with an analysis of the statistical biases and stereotypes that obscure these contributions and briefly indicates the cost of this invisibility to the countries involved as well as to the women themselves.  相似文献   

Investigating Flipped Learning: Student Self-Regulated Learning,Perceptions, and Achievement in an Introductory Biology Course     

Sarah Rae Sletten 《Journal of Science Education and Technology》2017,26(3):347-358

In flipped classrooms, lectures, which are normally delivered in-class, are assigned as homework in the form of videos, and assignments that were traditionally assigned as homework, are done as learning activities in class. It was hypothesized that the effectiveness of the flipped model hinges on a student’s desire and ability to adopt a self-directed learning style. The purpose of this study was twofold; it aimed at examining the relationship between two variables—students’ perceptions of the flipped model and their self-regulated learning (SRL) behaviors—and the impact that these variables have on achievement in a flipped class. For the study, 76 participants from a flipped introductory biology course were asked about their SRL strategy use and perceptions of the flipped model. SRL strategy use was measured using a modified version of the Motivated Strategies for Learning Questionnaire (MSLQ; Wolters et al. 2005), while the flipped perceptions survey was newly derived. Student letter grades were collected as a measure of achievement. Through regression analysis, it was found that students’ perceptions of the flipped model positively predict students’ use of several types of SRL strategies. However, the data did not indicate a relationship between student perceptions and achievement, neither directly nor indirectly, through SRL strategy use. Results suggest that flipped classrooms demonstrate their successes in the active learning sessions through constructivist teaching methods. Video lectures hold an important role in flipped classes, however, students may need to practice SRL skills to become more self-directed and effectively learn from them.  相似文献   

Measuring the severity of child maltreatment     

Litrownik AJ  Lau A  English DJ  Briggs E  Newton RR  Romney S  Dubowitz H 《Child abuse & neglect》2005,29(5):553-573

OBJECTIVE: The purpose was to identify different operational definitions of maltreatment severity, and then to examine their predictive validity. METHOD: Children and their primary caregivers participating in a consortium of ongoing longitudinal studies were interviewed when they were approximately 4 and 8 years of age to assess behavior problems, and developmental and psychological functioning. Four different severity definitions were identified and applied to 519 children who were reported for alleged maltreatment between Birth and the Age 8 interview. A taxonomy for defining maltreatment characteristics (Barnett, Manly, & Cicchetti, 1993) was applied to Child Protective Service records to define severity as (a) Maximum Severity within each of five maltreatment types, (b) Overall Maximum Severity across the five types, (c) Total Severity or the sum of the maximum severity for each of five types, and (d) Mean Severity or the average severity for those types of maltreatment alleged, during each of two time periods-Birth to Age 4, and Age 4 to Age 8. RESULTS: Regression analyses that controlled for socio-demographic factors, early maltreatment (Birth to Age 4), prior functioning (Age 4), and site revealed that (a) all four severity definitions for maltreatment reports between Age 4 and Age 8 predicted Age 8 behavior problems, (b) Maximum Severity by Type and Mean Severity predicted adaptive functioning at Age 8, and (c) only Maximum Severity by Type was related to anger, at Age 8. Follow-up regression analyses indicated that only Maximum Severity by Type, specifically physical abuse, accounted for outcomes, beyond maltreatment occurrence versus non-occurrence. CONCLUSION: The results suggest that maltreatment severity definitions that preserve ratings within types of maltreatment may be the optimal approach to measure the severity of children's experiences.  相似文献   

The Korean government's electronic record management reform: The promise and perils of digital democratization   总被引：1，自引：1，他引：0  

Kyong Rae  Kwang-Suk   《Government Information Quarterly》2009,26(3):525-535

Recently, the Korean government instituted a reform in its archives with the goal of increasing transparency in government and meeting the challenges of the new digital environment in records management. President Roh's administration focused on a “process and system” reform through a shift from paper-based records management to electronic records management. The E-jiwon task management system of the Office of the President, invented by President Roh himself, served as the archetype for the reform. This study explores and critiques the administration's choice of a “process and system” reform over institutional reform, examines the legal framework used to enact the reform and its shortcomings, and analyzes the benefits and deficiencies of the E-jiwon as a tool for democracy in the archives. It concludes that while the new digital environment can assist in promoting government transparency, technological change by itself is inadequate; ultimately, institutional change is necessary for true reform.  相似文献

Supplied visuals and imagery instructions in field independent and field dependent children’s recall     

Carol Carrier  Mary Rae Joseph  Cynthia L. Krey  Phyllis LaCroix 《Educational technology research and development : ETR & D》1983,31(3):153-160

Does showing children pictures that depict a story help them recall story content? Is having them form mental pictures of the story more effective? Is it better to show the pictures or give instructions to form mental images before or after the children hear the story? Do field independent and field dependent children respond differently? This study involving sixth graders found that imaging was the most effective method of instruction, regardless of whether instructions to image came before or after the listening period.  相似文献
