The Appraisement of Antioxidant and Oxidant Status in Women Undergoing Surgical Menopause

The present study was undertaken to study the impact of surgical menopause on oxidant and antioxidant status in relation to estrogen levels after 3 months of surgery. Total 130 women who had undergone total hysterectomy (TH) with or without bilateral salpingo-oophorectomy (BSO) were included in this study. The oxidant status was assessed by measuring plasma levels of malondialdehyde and antioxidant status was assessed by measuring superoxide dismutase, catalase, glutathione, glutathione peroxidase, estrogen, and Vitamin A, E and C levels. The malondialdehyde level was significantly increased (p < 0.05) in all women who underwent TH with or without BSO. Significant increased levels of superoxide dismutase were observed in women who underwent TH with BSO. The blood glutathione levels were significantly decreased in women after TH only but significantly increased in women who had undergone TH with BSO. The levels of estrogen, vitamin E and vitamin C were significantly decreased in women who underwent TH with BSO. The catalase, GPx and vitamin A did not differ significantly in all groups. The result suggests that surgical menopause is associated with oxidative stress which reiterates the fact that ovaries retain some function even after menopause.     

Primary humanities – a perspective from Northern Ireland

ABSTRACT

The word ‘humanities’ does not appear in the current Northern Ireland Curriculum (NIC). Geography and history are taught within an Area of Learning called ‘The World Around Us’ which also contains science and technology. The curriculum has a strong emphasis on an integrated, ‘connected learning’ way of teaching and learning. Religious Education is a separate subject that stands alongside, rather than within, the NIC, and the curriculum also includes a new Area of Learning – ‘Personal Development and Mutual Understanding’. The distinctive content and modes of teaching which the humanities subjects tend to encourage ought to be seen as particularly important in Northern Ireland – a part of the UK which has endured a complicated past and remains to a large extent segregated, both socially and educationally. This complicated past means that there is often wariness and reluctance on the part of teachers towards tackling controversial personal and social issues in the primary school.     

A possible “orality” for science?

The paper attempts to look at how the present objective and detached discourse of science, a specialized product of the literate tradition, tends to negatively influence learning among children, especially those belonging to a signficantly oral culture. It calls for a fundamental redefinition of scientific discourse and urges school science to review its own communicability, to address the disparate linguistic and conceptual structures brought to the learning situtation by students of diverse cultures, and to allow for a smooth and unoppressive transition to the standardized register.     

Improving Conceptual Understanding and Representation Skills Through Excel-Based Modeling

The National Research Council framework for science education and the Next Generation Science Standards have developed a need for additional research and development of curricula that is both technologically model-based and includes engineering practices. This is especially the case for biology education. This paper describes a quasi-experimental design study to test the effectiveness of a model-based curriculum focused on the concepts of natural selection and population ecology that makes use of Excel modeling tools (Modeling Instruction in Biology with Excel, MBI-E). The curriculum revolves around the bio-engineering practice of controlling an invasive species. The study takes place in the Midwest within ten high schools teaching a regular-level introductory biology class. A post-test was designed that targeted a number of common misconceptions in both concept areas as well as representational usage. The results of a post-test demonstrate that the MBI-E students significantly outperformed the traditional classes in both natural selection and population ecology concepts, thus overcoming a number of misconceptions. In addition, implementing students made use of more multiple representations as well as demonstrating greater fascination for science.     

Academic Optimism and Teacher Education

Abstract

Stereotypes are a particularly insidious factor in the formation of pre‐ and in‐service teachers’ images of students. Teachers who rely on stereotypes rather than try to see the students behind them run the risk of letting cultural and individual biases work to their own disadvantage and to the disadvantage of the next generation of high school students. This article describes a project called Teaching and Learning Together that brings preservice teachers into direct dialogue with high school students with the goal of helping preservice teachers learn to attend to high school students and analyze the pedagogical implications of that attention prior to undertaking teaching responsibilities.     

Internationalising the Student Experience: Preparing Instructors to Embed Intercultural Skills in the Curriculum

The Internationalising the Student Experience Project was devised and piloted as a teaching innovation to improve the intercultural awareness of instructors and, subsequently, that of their domestic and international students. In this article we claim that instructor preparation in the use of the Alliance Building and Cultural Mapping tools of the international EXCELL (Excellence in Cultural Experiential Learning and Leadership) Program can provide a base for institutionalised support. We report and discuss this approach and the outcomes to the challenges of and opportunities for internationalising the curriculum in the broader higher education context.     

The Impact of teacher behavior,teacher sex,and student sex upon student self-disclosure

The effects of systematically varied teacher verbal and nonverbal evaluative behavior upon student willingness to self-disclose were studied within an experimental microlesson. Subjects were 126 sixth-grade students who were removed from their classrooms to participate in a vocabulary lesson with one of the four experimental teachers (two male and two female). Within each experimental condition, the teacher employed one of four evaluative styles: (1) verbally and nonverbally positive, (2) verbally positive and nonverbally negative, (3) verbally negative and nonverbally positive, or (4) verbally and nonverbally negative. The data analysis indicated that teachers' verbal behavior influenced self-disclosure. The magnitude of student self-disclosure scores was a direct function of the positiveness of teacher verbal behavior. Nonverbal behavior also influenced self-disclosure, interacting with student sex. This effect varied across individual teachers, however, and no consistent pattern was evident.     

An evaluation of Early Reading First (ERF) preschool enrichment on language and literacy skills

Early Reading First (ERF) was created to address problems related to language and development among economically disadvantaged and language-minority preschool children through quality classroom processes, professional development, and instruction. More than any previous initiative, ERF specifies what early literacy instruction should look like in preschool classrooms; however, to date, scant research has examined the effectiveness of the program. In this quasi-experimental study, the effectiveness of ERF preschool enrichment was evaluated through comparison with the performance of demographically similar children from the same school district who received practice-as-usual instruction. As in previous research, ERF-enriched instruction was found to enhance acquisition of alphabet knowledge and print concepts. Unlike previous studies, however, it was also found to promote vocabulary development. Multilevel models were chosen to take into account the non-independence of students in the same classroom in testing the effects of ERF.
