Abstract: Calcium is an essential element for good growth and development of the organism, and its requirement is increased at school age. Low socio-economic populations of developing countries such as Colombia may have food deficiency of this mineral in schoolchildren that could be reflected in calcium biochemical indicators, bone alterations and anthropometric indicators. The objective of this investigation was to evaluate some calcium biochemical indicators in a group of schoolchildren of low socioeconomic level from Barranquilla city and to correlate with body mass index. 60 schoolchildren aged 7 to 15 years were selected from Jesus’s Heart Educational Institution in Barranquilla-Atlántico, apparently healthy, without suffering from infectious or gastrointestinal diseases, without habits of drinking alcohol or smoking another hallucinogenic substance and without taking supplementation with calcium in the last six months or another substance that compromises bone metabolism. The research was approved by the ethics committee at Universidad del Atlántico. The selected children were invited to donate a blood and urine sample in a fasting time of 12 hours, the serum was separated by centrifugation and frozen at ˗20 ℃ until analyzed and the same was done with the urine sample. On the day of the biological collections, the weight and height of the students were measured to determine the nutritional status by BMI using the WHO tables. Calcium concentrations in serum and urine (SCa, UCa), alkaline phosphatase activity total and of bone origin (SAPT, SBAP) and urinary creatinine (UCr) were determined by spectrophotometric methods using commercial kits. Osteocalcin and Cross-linked N-telopeptides of type I collagen (NTx-1) in serum were measured with an enzyme-linked inmunosorbent assay. For statistical analysis the Statgraphics software Centurium XVII was used. 63% (n = 38) and 37% (n = 22) of the participants were male and female, respectively. 78% (n = 47), 5% (n = 3) and 17% (n = 10) had a normal, malnutrition and high nutritional status, respectively. The averages of evaluated indicators levels were (mean ± SD): 9.50 ± 1.06 mg/dL for SCa; 181.3 ± 64.3 U/L for SAPT, 143.8 ± 73.9 U/L for SBAP; 9.0 ± 3.48 ng/mL for osteocalcin and 101.3 ± 12.8 ng/mL for NTx-1. UCa level was 12.8 ± 7.7 mg/dL that adjusted with creatinine ranged from 0.005 to 0.395 mg/mg. Considering serum calcium values, approximately 7% of school children were hypocalcemic, 16% hypercalcemic and 77% normocalcemic. The indicators evaluated did not correlate with the BMI. Low values were observed in calcium urinary excretion and high in NTx-1, suggesting that mechanisms such as increase in renal retention of calcium and in bone remodeling may be contributing to calcium homeostasis.
Abstract: Art education is often ignored in syllabus of developing countries like India and in educational planning for development but now days Indian Art with a global recognition is becoming an integral part of the education at all levels. The term art, widely used in all parts of the modern world, carried varied significance in India as its meaning was continuously being extended, covering the many varieties of creative expression such as painting, sculpture, commercial art, design, poetry, music, dance, and architecture. Over the last 100 years Indian artists of all forms have evolved a wide variety of expressive styles. With the recommendations and initiatives by Government of India, Art Education has subsequently gained pace at the school level as a mandatory subject for all making a path way for students with a creative bend of mind. This paper investigates curriculum in various schools of the country at secondary and senior secondary levels along with some eminent institutions running the program. Findings depicted the role of art education and justified its importance primarily with commercial art being perceived to be essential for students learning skills for economic gain in their career ahead. With so many art colleges spread across India, emerging artists and designers are being trained and are creating art of infinite variety and style and have opened up many career avenues. Commercial Art being a plethora of artistic expressions has confidently come of age wherein a creative perception is mixed with an introspective imagination to bring out multi faceted career options with a significant future enveloped in art. Visual arts in education thus is an expanding field of result assured research.
Abstract: This study investigated some results of the use of
digital art tools by junior school children in order to discover if these
tools could promote artistic ability and creativity. The study considers
the ease of use and usefulness of the tools as well as how to assess
artwork produced by digital means. As the use of these tools is a
relatively new development in Art education, this study may help
educators in their choice of which tools to use and when to use them.
The study also aims to present a model for the assessment of
students’ artistic development and creativity by studying their artistic
activity. This model can help in determining differences in students’
creative ability and could be useful both for teachers, as a means of
assessing digital artwork, and for students, by providing the
motivation to use the tools to their fullest extent. Sixteen students
aged nine to ten years old were observed and recorded while they
used the digital drawing tools. The study found that, according to the
students’ own statements, it was not the ease of use but the successful
effects the tools provided which motivated the children to use them.
Abstract: In this article, we discuss project-based learning in the context of a wheel garden as an instructional tool in science and mathematics education. A wheel garden provides multiple opportunities to teach across the curriculum, to integrate disciplines, and to promote community involvement. Grounded in the theoretical framework of constructivism, the wheel garden provides a multidisciplined educational tool that provides a hands-on, non-traditional arena for learning. We will examine some of the cultural, art, science, and mathematics connections made with this project.
Abstract: This research investigates the use of digital technology
namely interactive multimedia in effective art education provided by
museum. Several multimedia experience examples created for art
education are study case subjected to assistance audiences- learning
within the context of existing theory in the field of interactive
multimedia.
Abstract: In our current political climate of assessment and
accountability initiatives we are failing to prepare our children for a
participatory role in the creative economy. The field of education is
increasingly falling prey to didactic methodologies which train a
nation of competent test takers, foregoing the opportunity to educate
students to find problems and develop multiple solutions. No where is
this more evident than in the area of art education. Due to a myriad of
issues including budgetary shortfalls, time constraints and a general
misconception that anyone who enjoys the arts is capable of teaching
the arts, our students are not developing the skills they require to
become fully literate in critical thinking and creative processing.
Although art integrated curriculum is increasingly being viewed as a
reform strategy for motivating students by offering alternative
presentation of concepts and representation of knowledge acquisition,
misinformed administrators are often excluding the art teacher from
the integration equation. The paper to follow addresses the problem
of the need for divergent thinking and conceptualization in our
schools. Furthermore, this paper explores the role of education, and
specifically, art education in the development of a creatively literate
citizenry.
