We report on the development of an after-school and summer-based science, technology, engineering, and mathematics curriculum infused with the arts and social emotional learning content (STEAM SEL). Its design was motivated by theory and research that suggest that STEM education is well-suited for teaching empathy and other emotion-related skills. In this paper, we describe the activities associated with the development and design of the program and the curriculum. We provide expert-ratings of the STEAM and social emotional elements of the program and present instructor and participant feedback about the program’s content and its delivery. Our results revealed that infusing the arts and social emotional learning content into science education created a holistic STEM-related curriculum that holds potential for enhancing young children’s interest in and appreciation for science and its applications. The data also suggested that the program was well-developed and, generally well-executed. However, experts rated the STEAM elements of the program more positively than the SEL elements, especially with regard to sequencing of lessons and integration among the lessons and hands-on activities, indicating that program revisions are warranted. 相似文献

Researchers have argued against deficit-based explanations of students’ difficulties with mathematical sense-making, pointing instead to factors such as epistemology. Students’ beliefs about knowledge and learning can hinder the activation and integration of productive knowledge they have. Such explanations, however, risk falling into a ‘deficit trap’—substituting a concepts/skills deficit with an epistemological one. Our interview-based case study of a freshman engineering major, ‘Jim,’ explains his difficulty solving a physics problem (on hydrostatic pressure) in terms of his epistemology, but avoids a deficit trap by modeling the dynamics of his epistemological stabilities and shifts in terms of fine-grained cognitive elements that include the seeds of epistemological expertise. Specifically, during a problem-solving episode in the interview, Jim reaches and sticks with an incorrect answer that violates common sense. We show that Jim has all the mathematical skills and physics knowledge he would need to resolve the contradiction. We argue that his difficulty doing so stems in part from his epistemological views that (i) physics equations are much more trustworthy than everyday reasoning, and (ii) physics equations do not express meaning that tractably connects to common sense. For these reasons, he does not view reconciling between common sense and formalism as either necessary or plausible to accomplish. But Jim’s in-the-moment shift to a more sophisticated epistemological stance highlights the seeds of epistemological expertise that were present all along: he does see common sense as connected to formalism (though not always tractably so), and in some circumstances, this connection is both salient and valued. 相似文献

Thyroid hormones regulate the renal hemodynamics and basal metabolic rate of most cells. This hospital-based case-control
study was done to evaluate the changes in biochemical markers of liver and kidney function in hypothyroid subjects before
and after treatment. The study included 176 subjects randomly selected from Thyroid clinics. Serum T3, T4, TSH, Liver and Kidney Function tests were analysed using standard kits. Forty-six hypothyroid patients were re-evaluated
6 weeks after thyroxine substitution therapy. Hypothyroid subjects (n=80) showed significantly raised serum creatinine and
uric acid levels as compared to euthyroid subjects (n=96). After 6 weeks of thyroxine replacement, serum creatinine and uric
acid decreased significantly and were comparable to euthyroid group. A positive correlation of ALT, AST, uric acid, protein
and albumin with TSH levels (p<0.05) and negative correlation of serum T4 levels with ALT, AST, proteins (p<0.05) was observed in the hypothyroid group. Hypothyroidism results in reversible impairment
of hepatorenal function. 相似文献

Neural tube defects are congenital structural abnormalities of the brain and vertebral column resulting from improper or non-timely
closure of the neural tube. Prevalence of neural tube defects is reported to be higher among women with diabetes mellitus
and obesity. This study was designed to investigate the relation between the presence of dyslipidemia in antenatal patients
and the risk of fetal neural tube defects. The present study was an observational, cross-sectional study involving 129 pregnant
women in 16 to 18 weeks gestation period. Of these, 80 women had normal pregnancies and 49 were clinically high-risk cases
for neural tube defects. Fasting blood samples were analyzed for blood sugar and lipid profile by enzymatic assay and alpha-fetoprotein
levels using Enzyme Immunoassay. Alpha-fetoprotein (AFP) values were converted to Multiples of Median (MoM) appropriate for
the gestational age. Based on AFP values, women were labeled as screen negative (AFP <2 MoM, n= 102) and screen positive (AFP
> 2 MoM, n =27). Screen positive women were further evaluated by ultrasound and 21 women were found to carry a neural tube
defects positive pregnancy. Statistical analysis was done on SPSS software. Body weight of the women showed a significant
positive correlation with serum triglycerides, plasma sugar and AFP MoM values. A significant difference was observed in serum
cholesterol levels (p= 0.038), triglycerides (p=0.001) and plasma sugar levels (p=0.002) between normal women and those with
neural tube defects positive pregnancy. The Odds ratio for neural tube defects risk in dyslipidemic cases was 24.23 (CI 4.73
− 148.60) with a relative risk of 12.12. Dyslipidemia especially hypertriglyceridemia was found to be significantly associated
with fetal neural tube defects. 相似文献

Determination of ammonia level in blood is important, especially in the diagnosis of hepatic disorders. An indigenously purified
enzyme was used in the standardisation of the assay. The assay is a two reagent system, requires five minutes for completion
and can be performed at temperature between 25–27°C. Performance of the assay was assessed by linearity, imprecision, functional
sensitivity and interference studies. Lyophilised reagent I and reagent II were found stable for at least one year. The plasma
level of ammonia for the controls was 13.7±7.3 μMol/L, whereas for subjects of hepatic disorders, it was 69.1±32.4 μMol/L
(P<0.001). The functional sensitivity was between 2–1000 μMol/L. Within-run coefficient of variation was between 1.1–2.0%
and between-run coefficient of variation was between 1.9–3.7%. The mean recovery after dilution was 99.6%. The present method
can estimate ammonia up to 1000 μMol/L without dilution of sample. Assay time of five minute may be shortened to one minute.
This method is suited for routine clinical use in treatment of hepatic disorders. 相似文献

The relationship between materialism and social-emotional behavioural difficulties (SEBDs) was assessed by comparing a sample of adolescents receiving in-school behavioural support with adolescents not receiving any support. All participants completed the Youth Materialism Scale and the Strengths and Difficulties Questionnaire. Binary logistic regression indicated that adolescents who reported higher levels of materialism were more likely to be classified into a group considered ‘at-risk’ for developing conduct and peer problems. Hierarchical logistic regression assessed the moderation of behavioural support and indicated that adolescents in receipt of behavioural support who reported higher levels of materialism were at a greater risk of hyperactivity in comparison to those who receive support but reported lower levels of materialism. For adolescents not receiving behavioural support, less materialistic attitudes placed them at a greater risk of hyperactivity. These findings highlight the importance of distinguishing between different SEBD typologies and the potential effects of materialism during adolescence. 相似文献

This review explores Jackson and Seiler’s “I am smart enough to study postsecondary science: A critical discourse analysis of latecomers’ identity construction in an online forum” by considering the analytic framework for figured worlds guiding this study. We consider the specific affordances of cultural production theory for examining how sociohistorical and cultural discourses of science as elite impact individuals at every level of education. We then extend this discussion by exploring how an informal learning space at a prestigious science museum was designed to explicitly tackle cultural discourses of science as elite that act as barriers to identification with science. 相似文献
