중학교 과학과 탐구영역의 평가에 대한 한국과 영국 비교연구

조정란,Mary Ratcliff 한국교육과정평가원 2006 교육과정평가연구 Vol.9 No.2

TIMSS(Third International Mathematics and Science Study)의 국제 비교와 더불어 이 연구는 영국과 한국의 국가 교육과정 내용과 평가면에서 분명한 공통점과 차이점을 보여주고 있다. 비록 국가 교육과정의 기원에 있어서 역사적으로 문화적으로 다른 뿌리를 가지고 있음에도 불구하고 영국과 한국의 국가 교육과정은 과학탐구를 강조하여 학생들에게 과학적 소양을 함양하고자 하는 공통의 교육목표를 향하여 발전해 가고 있다. 문헌분석 방법을 통해서, 과학탐구의 영역에 대한 두 국가 교육과정 내용과 평가 부분의 분석에 의하면, 영국의 국가 교육과정의 내용과 평가 영역이 위에서 언급한 교육과정 목표를 보다 더 충실하게 반영하고 있음이 드러났다. 반면 한국의 국가 교육과정의 내용과 평가면에서는 위의 교육목표를 충실하게 반영하고 있다고 볼 수 없었으며 특히 평가문항에서는 위의 교육목표가 불일치되는 항목이 많은 것을 알 수 있었다. 비록 한국의 중학교 학생들은 국제 비교 연구에서 꾸준하게 영국의 학생들보다 좋은 성적을 거두고 있으나, 위와 같이 교육목표를 충실하게 교과과정의 내용과 평가에 반영하는 질적인 면에서 차이를 보이고 있음을 알 수 있다. 본 연구에서는 영국의 KS3 시험지와 한국의 고입선발시험의 내용을 Klopfer의 분류표를 이용하여 비교 분석하였다. 영국의 KS3 시험지는 문항이 한국의 고입선발시험의 문항들에 비해 학생들의 다양한 탐구능력을 평가하고 있었으며 과학탐구 문항이 전년에 비해 늘어나고 탐구조사 문항과 과학의 본질에 대한 문항이 새로이 첨가되는 등의 변화를 보여주고 있는 반면 한국의 고입선발시험은 탐구 영역에 대한 양적 또는 질적 변화가 거의 없는 것으로 드러났다. 고입선발시험 문항에서는 과학탐구 영역이 자료분석에 집중된 현상을 보여주고 있다. 한편, Bloom의 분류표에 의한 분석에 따르면, 한국의 고입선발시험 문항은 영국의 KS3 시험지에 비해 높은 인지능력을 요구하는 문항이 많은 것을 알 수 있었다. 즉, 영국의 KS3 시험지는 ‘지식과 이해’ 영역이 많은 반면, 한국의 고입선발시험 문항에서는 ‘적용’ 영역이 현저히 많은 것이 특징이었다. 이 연구는 한국과 영국의 중학교 국가 교육과정의 목표, 내용과 평가의 측면에서 과학탐구 영역에 대한 공통점과 차이점을 잘 보여주고 있다. Along with TIMSS(Third International Mathematics and Science Study), this research show many commonalities and differences in the National Curricula and assessment. Although the National Curricula stem from different historical and cultural value systems, the aims of the National Curriculaare heading toward a similar direction which are aiming at fostering future citizenship for young people putting emphasis on scientific enquiry as a core of scientific literacy. Through the documentary analysis, although Korean pupils consistently have achieved higher marks than English counterparts in international comparison tables, the content of the curriculum and assessment in England reflect more fully the aims of the curriculum. On the other hand, there is less consistency between the aims and content of the curriculum and the assessment. In addition, the standardised KS3 test papers in England assess students' various ability than Korean counterparts showing wider spectrum of Klopfer's specifications. In particular, scientific enquiry questions in Korean test papers concentrate on the area of data interpretation mainly. The Korean test papers appear to be higher cognitive domain in Bloom's taxonomy than English ones reflecting more of the questions demanding higher conceptual understanding. The full paper demonstrates commonalities and differences between two assessment systems at KS3 and middle school level of the National Curricula.

Validation of Sensory Outcome Measure : Findings from the 2011 Survey of Pathway to Diagnosis and Services

Mi Jung Lee,Karen Ratcliff,Claudia L. Hilton,Ickpyo Hong 대한작업치료학회 2019 대한작업치료학회지 Vol.27 No.5

Objective: To evaluate item-factor structures of the 15 sensory items from the Survey of Pathways to Diagnosis and Services (Pathways) and examine the best fitting model. Methods: The study subjects were 1,968 children aged 6-17 years, who had ever been diagnosed with Autism Spectrum Disorder (ASD) and/or Intellectual Disability (ID). Factor analyses and item response theory models were used to determine the best fitting item-factor structure of the sensory items. The Strengths and Difficulties Questionnaires (SDQ) was used to test the concurrent validity of the sensory severity estimates. Results: A bifactor MIRT model (a general and four sensory factors) was selected as the best fitting model. All items statistically fitted to the bifactor model (p > .01) and showed moderate correlations with all five subscales of the SDQ (r s = .31 ~.51, p < .0001). The general sensory score differentiated the four different diagnostic groups (ASD, ID, ASD with ID, and no current symptoms) [F (3,1961) = 207.4, p < .0001]. Conclusion: The Pathways sensory items yielded reliable estimates of the general and each corresponding sensory factor by applying a bifactor MIRT model. The sensory score can be used as a valid sensory measure in the population survey.

A Comparison of two Computer-Assisted Cognitive Training Program Outcomes for Breast Cancer Survivors: A Pilot Study

Theresa M. Smith,Karen Ratcliff,Theresa M. Smith 대한작업치료학회 2019 대한작업치료학회지 Vol.27 No.3

Purpose: Breast cancer survivors(BCS) have memory, attention, processing speed, and/or executive functionimpairment affecting their quality of life(QOL) and function. Study aims were: (1) compare computer-assistedcognitive training with visual exercises to one with audio+ visual exercises, and (2) gain insight into therelationship between engagement in meaningful activities, cognitive deficits and QOL. Methods: This pilot study used an experimental design with 24 women. Pre and post measures assessed workingmemory, perceived cognition, QOL and engagement in meaningful activities. Results: Treatment effects were not significant for working memory or engagement in meaningful activities. Visualgroup participants scored significantly better on perceived cognitive function posttest test(M = 91.62, SD = 21.75)than pretest(M = 74.48, SD = 29.00), p = .010 and significantly higher on QOL posttest(M = 6.42, SD = 1.27)than pretest(M = 5.60, SD = 1.76), p = .004. Pretest perceived cognitive function was significantly associatedwith pretest(ρ = .617, p < .001) and posttest(ρ = .436, p < .05) QOL. Conclusion: Computer-assisted cognitive training with visual exercises appears to improve perceived cognitivefunction and QOL for BCS. A positive relationship exists between perceived cognitive function and QOL.

나에게 휴식을 주세요 : 휴식에 대한 논쟁

Barbie Norvell,Nancy Ratcliff,& Gilbert Hunt,김은영 역 대한어린이교육협회 2010 어린이교육 Vol.- No.12

저자들은 최근에 유아교사와 그들이 경험했던 몇 가지 스트레스에 대해 이야기할 기회 가 있었다. 여러번에 걸쳐 유아와 교사의 교육과정과 일상생활이 표준화된 평가에서 연간 능력평가(AYP)의 기대치에 도달하기 위해 유아에게 어떤 영향을 미치고 있는지에 대해 설 명을 들었다. 교사들은 높은 기준이 중요하다는 것을 확실히 알았고 이 교사들은 유아들이 배울 수 있고 배워야한다는 사실에 동의를 명확히 했다. 하지만 그들의 교실 학습 환경은 부정적으로 변화되어온 것처럼 보인다. Nichols과 Berliner(2007)는 높은 기준의 시험이 교 사와 유아 모두에게 부정적인 영향을 끼친다고 주장했다. 이 저자들은 켐벨의 법칙이라는 현상을 제시했는데, 이 법칙은 사회적 의사결정에 양적지표(이 사례에서는 표준화된 시험 점수와 AYP)를 많이 사용하면 할수록 기존에 의도했던 평가과정(이 사례에서는 학교개선 과 유아학습)이 타락하며 왜곡될 가능성이 크다는 것이다.

Chinese Entrepreneurs, the Party-State, and Gender: Women Succeed in Business without the CCP

Chen, Minglu,Goldsmith, Benjamin E.,Ratcliff, Shaun 동아시아연구원 2022 Journal of East Asian Studies Vol.22 No.3

In this article, we take a gender perspective to explore the relationship between private entrepreneurs’ business success and their Chinese Communist Party (CCP) membership. We theorize that, due to male-dominated CCP-business networks, female entrepreneurs are not able to leverage CCP membership into greater business success. Observable implications of this are that women will experience little or no business advantage from Party membership, while men will experience a significant advantage. The independence of women's business success from Party connections allows the possibility that women have carved out an area of autonomy from the party-state. Using a series of national entrepreneur surveys collected between 2002 and 2012, we assess the degree of empirical support for our expectations. We show that the CCP does appear to function as an exclusive “boys’ club” in terms of profitable patronage or networks, while the most successful women tend not to be Party members. The surveys also provide some evidence consistent with a CCP effort to recruit successful female entrepreneurs in order to curtail their autonomy. Our findings suggest non-CCP female entrepreneurs are a significant but generally overlooked socio-economic group with considerable potential autonomy.
