Assessment innovation and student experience: a new assessment challenge and call for a multi-perspective approach to assessment research     

Sheena Bevitt 《Assessment & Evaluation in Higher Education》2015,40(1):103-119

The impact of innovative assessment on student experience in higher education is a neglected research topic. This represents an important gap in the literature-given debate around the marketisation of higher education, international focus on student satisfaction measurement tools and political calls to put students at the heart of higher education in the UK. This paper reports on qualitative findings from a research project examining the impact of assessment preferences and familiarity on student attainment and experience. It argues that innovation is defined by the student, shaped by diverse assessment experiences and preferences, and therefore its impact is difficult to predict. It proposes that future innovations must explore assessment choice mechanisms which allow students to shape their own assessments. Cultural change and staff development will be required to achieve this. To be accepted, assessment for student experience must be viewed as a complementary layer within a complex multi-perspective model of assessment, which also embraces assessment of learning, assessment for learning and assessment for lifelong learning. Further research is required to build a meta-theory of assessment to enhance the synergies between these alternative approaches and minimise the tensions between them.  相似文献   

Modulation of convulsive threshold of pentylene tetrazole by zinc     

N. Khanna  A. Garg  K. K. Sharma  R. Khosla 《Indian journal of clinical biochemistry : IJCB》1997,12(1):86-90

In the present study which was aimed to see the effect of zinc on pentylenetetrazole induced convulsive threshold in rats we found that zinc sulfate 100 μg intracerebroventricularly) and pentylenetetrazole (50 mg/kg intraperitoneally) produced dose related seizure activity; however, pretreatment with zinc decreased the threshold, increased the severity, incidence of multiple seizures and total duration of pentylenetetrazole induced seizures. Diazepam (5 mg/kg intraperitoneally) pretreatment increased the threshold and lowered the incidence of convulsions in zinc induced seizures which further confirms that the convulsive effect of zinc is through inhibition of gamma aimino butyric acid.  相似文献   

Assessment of oxidative stress and antioxidant status in age related cataract in a rural population     

A. K. Pradhan  A. K. Shukla  M. V. R. Reddy  N. Garg 《Indian journal of clinical biochemistry : IJCB》2004,19(1):83-87

Oxidative stress was assesed by estimating lipid peroxidation product (LPO) in the form of thiobarbituric acid reactive substances (TBARS), enzymatic antioxidants in the form of superoxide dismutase (SOD), catalase and nonenzymatic antioxidant vitamins e.g. vitamin C, β carotene and vitamin E in either serum or plasma or erythrocytes in 190 cases of age related cataract in the age group of 50–80 years. 190 cases were grouped into three morphological types namely, 73 cases of cortical, 77 cases of posterior subcapsular and 40 cases of nuclear cataract and values of LPO and antioxidants were compared with 78 cases of age matched healthy control groups. Plasma TBARS levels were cataract cases when compared with control groups. There were no significant differences in the erythrocyte levels of catalase and plasma levels of Vit E between cataract cases and control groups. No significant changes of parameters were seen among three different morphological types of age related cataract. The present study shows that the oxidative stress may play an important role in the age related cataract.  相似文献   

Narrative construction of professional teacher identity of teachers with dyslexia   总被引：1，自引：0，他引：1  

Eila Burns  Sheena Bell   《Teaching and Teacher Education》2011,27(5):952-960

This paper considers the development of teachers’ professional identity in the context of educators that have diverse backgrounds. We elucidate how teachers with dyslexia working in tertiary education use narrative resources to construct and negotiate their professional teacher identities. The analysis of narrative interviews, interpreted within the framework of positioning theory and the theories of narrative identity, indicated that the interviewees constructed several professional teacher identities that were closely linked to each teacher’s perception of their dyslexia. The experience of dyslexia was clearly evident as a positive element in each identity. Instead of seeing it as an obstacle it can become a part of the teacher’s own identity and can be used as a tool to thrive in their profession.  相似文献   

Can ‘pooling teaching tips’ be more than ‘pooling teaching tips’?

Abstract

There is increasing interest in how academic development of various kinds influences university teaching and student learning. To date the focus has been on formal, expert-led opportunities to learn how to teach. Our institution has developed a less formal, participant-led forum for teaching staff that was initially established to share ideas on teaching techniques and skills. We report here on participant-led research that explores if and how this model of group learning works, and how it might relate to other models that have been applied to tertiary teaching development. Authors adopted a self-study research framework incorporating a collaborative autoethnography. The data emphasises how participants use this forum as a community of practice, as a means for deep engagement with learning about teaching, and as a means to rationally manage their learning against a backdrop of challenges associated with learning to teach in research-led higher education.  相似文献   

An extended chemical analysis of gallstone     

P. Chandran  N. K. Kuchhal  P. Garg  C. S. Pundir 《Indian journal of clinical biochemistry : IJCB》2007,22(2):145-150

Chemical composition of gall stones is essential for aetiopathogensis of gallstone disease. We have reported quantitative chemical analysis of total cholesterol bilirubin, calcium, iron and inorganic phosphate in 120 gallstones from haryana. To extend this chemical analysis of gall stones by studying more cases and by analyzing more chemical constituents. A quantitative chemical analysis of total cholesterol, total bilirubin, fatty acids, triglycerides, phospholipids, bile acids, soluble proteins, sodium potassium, magnesium, copper, oxalate and chlorides of biliary calculi (52 cholesterol, 76 mixed and 72 pigment) retrieved from surgical operation of 200 patients from Haryana state was carried out. Total cholesterol as the major component and total bilirubin, phospholipids, triglycerides, bile acids, fatty acids (esterified), soluble protein, calcium, magnesium, iron, copper, sodium, potassium, inorganic phosphate, oxalate and chloride as minor components were found in all types of calculi. The cholesterol stones had higher content of total cholesterol, phospholipids, fatty acids (esterified), inorganic phosphate and copper compared to mixed and pigment stones. The mixed stones had higher content of iron and triglycerides than to cholesterol and pigment stones. The pigment stones were richer in total bilirubin, bile acids, calcium, oxalate, magnesium, sodium, potassium, chloride and soluble protein compared to cholesterol and mixed stones. Although total cholesterol was a major component of cholesterol, mixed and pigment gall stone in Haryana, the content of most of the other lipids, cations and anions was different in different gall stones indicating their different mechanism of formation.  相似文献   

Lotka's law and institutional productivity   总被引：1，自引：0，他引：1  

Suresh Kumar  Praveen Sharma  K. C. Garg 《Information processing & management》1998,34(6):775-783

The present study aims at determining the applicability of Lotka's law, negative binomial distribution and lognormal distribution for institutional productivity, in the same way as it is to authors and their productivity in the field of engineering sciences and the patents filed by industrial firms in laser S&T. The study indicates that non of the three distributions are applicable for institutional productivity in engineering sciences. However, Lotka's law holds good for full as well as truncated set of data for the patents filed by industrial firms.  相似文献   

Changes in serum copper levels in patients with malignant diseases undergoing radiotherapy     

H. R. Mali  S. A. Siddiqui  Madhur Garg  R. K. Singh  M. L. B. Bhatt 《Indian journal of clinical biochemistry : IJCB》1998,13(1):36-40

Present study repots changes in serum copper levels (SCL) in various neoplastic diseases undergoing radiotherapy. We estimated SCLs in 140 individuals comprising of 90 previously untreated patients with various malignancies and 50 healthy controls. Patients received radiation in doses of 40–70 Gy in 4–7 weeks. SCLs were again estimated in patients following irradiation. The mean SCL was significantly higher (P<0.001) in cancer patients as compared to healthy controls. It declined significantly (P<0.001) following irradiation. However, it remained significantly higher as compared to healthy controls (P<0.01). Highest fall in SCL was seen in complete clinical responders and least in non-responders to radiation treatment. Serial estimation of SCLs may be useful in the treatment monitoring of the neoplasms undergoing radiation treatment.  相似文献   

hs-CRP and oxidative stress in young CAD patients: A pilot study     

Suman B. Sharma  Seema Garg  Abhinav Veerwal  Sridhar Dwivedi 《Indian journal of clinical biochemistry : IJCB》2008,23(4):334-336

Premature coronary artery disease (CAD) is common in India. We, therefore, studied oxidative stress, dyslipidemia, and high sensitivity-C reactive protein (hs-CRP) levels in young CAD patients. Present study consisted of male CAD patients below 40 years and age and sex matched healthy controls (n=30 each). Fasting blood samples were analyzed for serum lipid profile, malondialdehyde, antioxidant enzymes and hs-CRP levels. Dyslipidemia was observed in 90% of the young CAD patients, of which 72.2% showed increased serum triglycerides and decreased HDL-cholesterol. LDL-cholesterol levels were high in 77.8%. Serum malondialdehyde and hs-CRP levels were increased significantly (p<0.0001) as compared to controls. hs-CRP levels were in high risk range in all the young patients. However, glutathione peroxidase activity was reduced significantly (p<0.05). Our data suggests that elevated hs-CRP levels along with dyslipidemia and oxidative stress adds to the predictive value of premature CAD in young Indians.  相似文献   

How do teachers in Ireland and England conceptualise dyslexia?     

Sheena Bell  Thérèse McPhillips  Mary Doveston 《Journal of Research in Reading》2011,34(2):171-192

This paper presents the findings of a comparative study using data from questionnaire surveys carried out in England (n=57) and Ireland (n=72). The researchers examine how teachers and teaching assistants who are currently teaching pupils with dyslexia in primary schools describe dyslexia and what may have influenced their conceptualisation. The paper examines teachers' responses both in terms of how they view their pupils presenting difficulties in the classroom, and how far they link these to underlying differences in cognitive processing. The researchers suggest ways in which this might influence their teaching in terms of methodology. Findings have been mapped to the Morton and Frith causal modelling framework. The implications of these findings for the training and support of teachers are discussed in the light of recent national initiatives to improve the teaching of dyslexic pupils in both countries.  相似文献
