Models and Paradigms in Kuhn and Halloun     

Paul Joseph Wendel 《Science & Education》2008,17(1):131-141

In Modeling Theory in Science Education, Halloun (2004) adopts the word ‘paradigm’, but his use of the term is radically different from that of Kuhn. In this paper, I explore some of the differences between Kuhn’s paradigms and Halloun’s paradigms. Where Kuhn’s paradigms are public, community-defining exemplars of practice, Halloun’s paradigms are private, individualized ways of thinking. Where Kuhn writes of the paradigm shift as a revolutionary, vision-altering conversion experience, Halloun writes of a gradual evolution from one way of thinking to another and an easy back-and-forth switch between paradigms. Since Kuhn’s paradigms are self-enclosed and incommensurable, there is no objective standard by which one paradigm can be shown to be superior to the other. But Halloun uses ‘viability’ as a standard for paradigm choice. Underlying all of this is the more basic question of whether the history of science is an appropriate metaphor for student progress in the classroom. I conclude with some brief thoughts on this question.  相似文献   

The Experiences of Low-Income Latina/o Families in an Urban Voucher,Parochial School     

Tatiana Joseph  William Vélez 《Journal of Latinos & Education》2017,16(2):143-155

Catholic schools have become a popular choice for many low income families Latino/a families. Families enrollment in these schools are often faced with the mandate to participate. However, regardless of the mandate, some schools often experience low parental participation. The purpose of this study is to document the experiences of low income, Latino/a families around parental involvement in hopes of understanding the reasoning for participating (or not) in their child’s school. The researchers conclude that families do not participate for a number of reasons including lack of opportunities, and an unwelcoming environment. The implications for Latina/o urban education are discussed.  相似文献

The Status of Career and Technical Education Undergraduate and Graduate Programs in the United States     

Edward C. Fletcher Jr.  Howard R. D. Gordon 《Peabody Journal of Education》2017,92(2):236-253

The purpose of this study was to examine undergraduate and graduate student enrollments, course delivery modes, and curricular trends and issues of CTE programs. Based on findings from 139 program/department coordinators, results emphasized that although CTE programs within institutions of higher education have declined in number (Fletcher, Gordon, Asunda, &; Zirkle, 2015 Fletcher, E., &; Djajalaksana, Y. (2015). Instructional strategy preferences in the career and technical education classroom. Journal of Research in Business Education, 57(1), 32–56. [Google Scholar]), student enrollments within those programs have remained steady compared to prior studies (Bruening et al., 2001 Bruening, T., Scanlon, D., Hodes, C., Dhital, P., Shao, X., &; Liu, S. (2001). The status of career and technical education teacher preparation programs. (Report No. V051A990004). Minneapolis, MN: The National Research Center for Career and Technical Education. [Google Scholar]; Lynch, 1990 Lynch, R. (1990). A national database on vocational teacher education (Report No. V051A80004-89). Berkeley, CA: National Center for Research in Vocational Education. [Google Scholar]). Even so, CTE program/department administrators have articulated that declining student enrollment is a major challenge within their programs. Additionally, the development of online courses and the impact of state/national educational reform initiatives were identified as major curricular trends for CTE programs. Recommendations include the need for CTE faculty to embrace online instruction, and for programs to use broader nomenclature of CTE/Workforce Education, instead of names of more traditional subdisciplines within the field to remain more accessible and sustainable in the future. The condition of undergraduate and graduate CTE programs will likely impact the viability and sustainability of CTE teacher preparation programs, recruitment of a talented and diverse CTE teaching force, continuity of the U.S. teaching workforce, and ability of K–12 teachers to maintain high-quality CTE programs.  相似文献

PASS cognitive processes,phonological processes,and basic reading performance for a sample of referred primary‐grade children     

Laurice M. Joseph  Megan E. McCachran  Jack A. Naglieri 《Journal of Research in Reading》2003,26(3):304-314

The purpose of this study was to explore the relationships among cognitive processing, phonological processing and basic reading skill performance. Cognitive theorists propose that Planning, Attention, Simultaneous and Successive (PASS) processes are related to various phonological skills. A sample of 62 Primary Grade children referred for reading problems were administered measures of cognitive processes (Cognitive Assessment System), phonological processes (Comprehensive Test of Phonological Processing) and basic reading achievement (Woodcock‐Johnson Tests of Academic Achievement‐III). Findings indicated that some cognitive processes were significantly related to phonological processes as well as basic reading skills. The strongest relationships were found between phonological memory and successive processes and between phonological awareness and basic reading performance.  相似文献   

Effects of vanadate supplementation on high fat-diet and diabetes-induced metabolic changes in liver     

Subbiah Pugazhenthi  Joseph F. Angel  Ramji L. Khandelwal 《Indian journal of clinical biochemistry : IJCB》1996,11(2):108-114

Normal and streptozotocin-induced diabetic rats were fed the control high starch-diet or a high fatdiet supplemented with or without sodium orthovanadate (1.5 mg/g diet) for six weeks. Plasma glucose, insulin and triacylglycerol levels and the activities of hepatic glycogen synthase, phosphorylase, glucose-6-phosphate dehydrogenase, malic enzyme, and ATP-citrate lyase were measured in these eight groups of rats. The high fat-diet increased the levels of insulin (P<0.05) and triacylglycerol (P<0.01) in plasma and decreased the activities (P<0.001) of phosphorylase (active from and total) and the lipogenic enzymes. Vanadate supplementation led to significant (P<0.001) decreases in the elevated insulin and triacylglycerol levels whereas the enzyme activities remained unaffected. Diabetes and fat diet in combination caused 3.7-fold increases in plasma glucose and triacylglycerol levels and vanadate decreased them by 58% and 74% respectively. Vanadate improved the activities of hepatic glycogen metabolizing and lipogenic enzymes in diabetic rats when they were fed on control starch-diet but not with high fat-diet. This study shows that vanadate normalizes hyperinsulinemia and hypertriglyceridemia but not the defective hepatic glycogen metabolism in high fat-fed rats.  相似文献   

Raised serum homocysteine levels in patients of coronary artery disease and the effect of vitamin B12 and folate on its concentration     

R Abraham  M Joseph John  R Calton  J Dhanoa 《Indian journal of clinical biochemistry : IJCB》2006,21(1):95-100

Homocysteine(Hcy) has been implicated as a novel risk factor of Coronary Artery Disease (CAD) among Asian Indians, but many studies done in India failed to reveal any direct correlation. It has also been reported that Folic acid and Vitamin B12 levels inversely affect serum levels of homocysteine. In this study, we looked at the levels of homocysteine among patients with CAD. The effect of Vitamin B12, Folate and other risk factors on homocysteine levels were also evaluated. Mean homocysteine levels in cases (22.81±13.9, n=70) were significantly higher (p=<0.001) than the controls (7.77±7.3, n=70). However no statistically significant correlation could be deduced between homocysteine Vitamin B12, and Folate. Cumulative analysis have indicated an increase in homocysteine levels among patients with CAD with every additional risk factor.  相似文献
