Perpectives in human biology

Review of Perpectives in Human Biology,volum:Issue 1,the perpective of international roster of those proffesionally involved in the study of human evolution.Howhere is this more evident than in the first lead articles,where the two lead articles.

The Issue of Perpective in Human Biology under consideration is not quite.The outlook of evolunionary Biology is largely missing or unused. To be sure,the field of Human Biology has been able to function effectively without much money to reference the evolution of theory for a long time ago.

The Volume under review represent the roster of paper presented at the joint conferent of The Australasion Society for Human Biology (AHSB) and The Commision of Human Ecology of The International Union of Antropological and Ethnological Science (IUAES) held in Adelaide,December 1-5,1997.There are 26 countributions from five of the nine sessions.

Two of the papers in the first session and one in the third were designated Keynote Addresses.The first of these setting The Evolutionary Scene is the paper by Colin P. Groves.He provide an interesting survey of the consequences of domistication in a comprehensive roster of animals with full domentation.(except for any mention of the pioneering work of Charles Darwin).

EFFECTIVE TEACHER COMMUNICATION SKILLS AND TEACHER QUALITY

As we move into the Twenty-First Century the education profession and politicians continue to grapple with the expectation of better or higher test scores from society. The National Council of Teachers in Mathematics (NCTM) considers communication so important that they list it as one of the principles of the NCTM Principles and Standards for the School Mathematics (NCTM, 2000).
The overarching strategy of this research is to gain an understanding of the relationship between communication skills and student achievement. It is conjectured that there is a relationship between the ability of an individual to effectively communicate their thought or idea and the success that individual will meet in the classroom as an instructor. The theoretical framework is based in the social constructivist theory of learning of Lev Vygotsky. The literature showed that effective communication is important in the learning theory of social constructivism. The literature also showed that the ability to communicate and the ability to pose questions are important attributes of an effective teacher. A survey of one school district’s fourth grade teachers was conducted and the student achievement scores of their students were tied to their respective teacher’s response. The instrument was developed by Plumeus to measure the communication skills across several sub-scales to include listening, and ability to deliver a concept or idea. This instrument was modified for this research as the sub-scales were initially dependent. Three models were developed from these sub-scales and demographic variables. About two-thirds of the teachers that responded have earned an advanced degree. The research found that teachers with less experience scored somewhat higher on reported communication skills than those teachers with more years of service. The research also found no difference between female and male teachers for self-reported communication skills. The ability to get the message across was significant in explaining the variances for the dependent variable citizenship. Also possessing an advanced degree added about 9 points to the mean student achievement score for citizenship. As for other variables not addressed in the research questions, it appears that female teachers add about 11 points to the mean student achievement scores for Science. Finally the sub-scale that was comparable between the large population of the company and the sub-scale that was significant in explaining the variance of the citizenship achievement scores was bility toget the message across. This was the one sub-scale that was connected to the larger population and the teacher population plus it was significant for the teacher population in explaining variance.
