Physicochemical characteristics of various milk samples available in Pakistan

We report physicochemical characteristics of various kinds of liquid milk commercially available in Pakistan in comparison with those of fresh natural milk from animals. Milk samples were collected from local markets at Peshawar, Pakistan,and analyzed for their physical features, including moisture, total solids, specific gravity, conductivity, viscosity and titratable acidity (lactic acid equivalent), and chemical components and macro-minerals, including total protein, casein, lactose, ash and minerals (Na, K and Mg). These items were compared with the physicochemical characteristics of the fresh natural milk samples from buffalo, cow and goat. The results were also compared with reported nutritional quality of milk from various countries and World Health Organization (WHO) standards. We found that all the physical features and chemical components of commercially available milk in Pakistan markets meet WHO's requirements, except for Na, K, Ca and Mg, which are below the standards.

The need for Saudi faculty and the media for instruction in Saudi Arabian universities

The past three decades have witnessed rapid growth and expansion in higher education. This study attempts to throw some light on the extent to which Saudi universities have attracted national faculty to match the level of increase in students' enrollment. Another important issue which is discussed in this article is the extent to which Arabic, the national language, is used as a medium of instruction in Saudi universities.Saudi government publications, as well as some international statistical documents, have been utilized in evaluating the possibility of achieving a national faculty and the possibility of using Arabic as the medium of instruction. Practical suggestions are offered to help the higher educational system in Saudi Arabia overcome some of the current problems.     

Preparation of counsellors in Pakistan: A proposed model

Summary This paper proposes a comprehensive counselor preparation model within the philosophical and religious beliefs of Pakistan. A series of courses are presented to provide a cohesive and comprehensive body of knowledge to counselors to work in educational, business, health and community settings. The proposed curriculum reflects the philosophy, beliefs, and values of the country in terms of human development, life/career and educational planning. Furthermore, this model proposes a pre-service preparation to replace the current in-service preparation model for counselors.Paper presented at the Tenth International Round Table for the Advancement of Counselling (Working Group: The Training of Counsellors), University of City-Dorigny.

Learning sorting algorithms through visualization construction

Recent increased interest in computational thinking poses an important question to researchers: What are the best ways to teach fundamental computing concepts to students? Visualization is suggested as one way of supporting student learning. This mixed-method study aimed to (i) examine the effect of instruction in which students constructed visualizations on students’ programming achievement and students’ attitudes toward computer programming, and (ii) explore how this kind of instruction supports students’ learning according to their self-reported experiences in the course. The study was conducted with 58 pre-service teachers who were enrolled in their second programming class. They expect to teach information technology and computing-related courses at the primary and secondary levels. An embedded experimental model was utilized as a research design. Students in the experimental group were given instruction that required students to construct visualizations related to sorting, whereas students in the control group viewed pre-made visualizations. After the instructional intervention, eight students from each group were selected for semi-structured interviews. The results showed that the intervention based on visualization construction resulted in significantly better acquisition of sorting concepts. However, there was no significant difference between the groups with respect to students’ attitudes toward computer programming. Qualitative data analysis indicated that students in the experimental group constructed necessary abstractions through their engagement in visualization construction activities. The authors of this study argue that the students’ active engagement in the visualization construction activities explains only one side of students’ success. The other side can be explained through the instructional approach, constructionism in this case, used to design instruction. The conclusions and implications of this study can be used by researchers and instructors dealing with computational thinking.     

Isolation and distinctiveness in the design of e-learning systems influence user preferences

When faced with excessive detail in an online environment, typical users have difficulty processing all the elements of representation. This in turn creates cognitive overload, which narrows the user's focus to a few select items. In the context of e-learning, we translated this aspect as the learner's demand for a system that facilitates the retrieval of learning content – one in which the representation is easy to read and understand. We hypothesized that the representation of content in an e-learning system's design is an important antecedent for learner preferences. The aspects of isolation and distinctiveness were incorporated into the design of e-learning representation as an attempt to promote student cognition. Following its development, the model was empirically validated by conducting a survey of 300 university students. We found that isolation and distinctiveness in the design elements appeared to facilitate the ability of students to read and remember online learning content. This in turn was found to drive user preferences for using e-learning systems. The findings provide designers with managerial insights for enticing learners to continue using e-learning systems.     

Role Conflict and the Dilemma of Palestinian Teachers in Israel

This paper explores the dynamics of conflicting role expectations among Palestinian teachers in Israel while focusing on the ways by which these expectations are generated and shaped by the broader sociopolitical context of the Israeli-Palestinian conflict and its impact on the educational system. Following a brief review of the historical background and the changing role patterns among Palestinian teachers in general, the paper focuses on Palestinian education in Israel and the role of Palestinian teachers within it. The central argument is that the Israeli authorities have been systematically using formal education and the teachers' role in order to repress national identity and awareness among Palestinian students. Data from interviews with Palestinian student activists about the contribution of the formal education to their national identity is used to illustrate the dilemmas and challenges experienced by their teachers.     

An introduction to education research methods: exploring the learning journey of pre-service teachers in a transnational programme

Internationally there is interest in developing the research skills of pre-service teachers as a means of ongoing professional renewal with a distinct need for systematic and longitudinal investigation of student learning. The current study takes a unique perspective by exploring the research learning journey of pre-service teachers participating in a transnational degree programme. Using a case-study design that includes both a self-reported and direct measure of research knowledge, the results indicate a progression in learning, as well as evidence that this research knowledge is continued or maintained when the pre-service teachers return to their home university. The findings of this study have implications for both pre-service teacher research training and transnational programmes.     

Global citizenship education: mainstreaming the curriculum?

There has been a resurgence of interest in global education in the UK as global issues are included within the requirements of citizenship education in national curricula. This paper examines the significance attached to global citizenship through Citizenship as a statutory subject at Key Stages 3 and 4 within the National Curriculum for England. Drawing on a web‐based project funded by the UK Department for International Development, the paper analyses a number of secondary school texts designed to support teachers and students in incorporating global perspectives into citizenship education. It seeks to answer the question: in what ways is global citizenship being mainstreamed? It suggests that NGOs and commercial publishers have different but complementary approaches to resources for global citizenship and that there is a strong case for greater collaboration between the two sectors.
