During the teaching process, it＇s of great important to develop the overall quality of the students, including morality, intelligence, physic, aesthetics, and labor. Physical education, as a task of the course of education, to a great extent, has the responsibility and obligation to develop students＇ ability for innovation. As regard to the education and instruction of creative ability, it must go through a complete change from the ideological level. We need to enhance students＇ enthusiasm for sports. By learning the basic knowledge of sports, as well as teaching and learning of motor skills, students will be developed in the ability of independent thinking and creation.

Creationism and Evolution Views of Brazilian Teachers and Teachers-to-Be

This paper aims at assessing the evolutionist and creationist conceptions of Brazilian teachers. The work is developed within the framework of the European project BIOHEAD-CITIZEN （biology, health and environmental education for better citizenship）, which takes into account that scientific knowledge and teachers＇ attitudes and values can influence the teaching practices. The large questionnaire BIOHEAD-CITIZEN, which was constructed to be applied in 19 countries in Europe, Africa and Middle East countries, was applied, in this study, to six groups of Brazilian teachers： primary school teachers, biology teachers and Portuguese language teachers and corresponding teachers-to-be. For this paper the answers to questions about evolution were used as dependent variables. Descriptive and multivariate analyses were carried out. Biology teachers and biology teachers-to-be gave more importance to the natural selection and the evolution process than the other groups of teachers. Comparing to the BIOHEAD-CITIZEN countries, the total Brazilian sample showed a higher percentage of creationist conceptions, particularly the Brazilian biology teachers and teachers-to-be. As discussed herein, this may not be an obstacle for teaching evolution as they accept both creationist and evolutionist concomitantly.

Cultural and Socio-economical Dimensions a- Human Reproduction and Sex Education in the Biology Textbooks of Eight Countries

This study was carried out within the European research project ＂Biology, Health and Environmental Education for Better Citizenship＂. It is a comparative analysis of textbooks from eight Mediterranean countries which differ by their cultures, their socio-economical levels, and their religions. This work is focused on the sensitive educational topic ＂Human Reproduction and Sex Education＂. And 43 biology textbooks are analyzed among eight countries： four are in Europe and four in Africa and Middle East. Grids were built to identify implicit values in the texts and images. It is a more precisely explicit or implicit presence of cultural, socio-economical, and ethical dimensions. The investigation concerns whether the authors of textbooks present differently this theme depending on the socio-cultural, ethical, and religious contexts. The content of the textbooks was analyzed as reflecting the conceptions of their authors and publishers. The outcomes of the analyses show that several textbooks present images of human beings restricted to only one ethnic type, usually white-skinned and with fair hair. The social, cultural, economical, and ethical dimensions were generally absent, except for some interest for them in few European textbooks.

Cultural Presence of the Cretan Biodiversity in the Minoan Period and nowadays： A Discovery School Teaching Approach

The educational project prepared for students of High School 15-17 years old with the subject of Biodiversity in Minoan Period and Nowadays. It was an interdisciplinary approach of ecological and cultural views of biodiversity. Special educational material was prepared with photos and texts of archaeological excavations and field sampling which was used in real and virtual environment, in t~ discovery teaching of Natural Sciences and History subjects. Students, in a scientific research project with constructive teachings, followed the procedures by which scientists gather, analyze, synthesize, process and evaluate information of organisms of Crete since 4000 years. Crete is located between the natural limits of three continents, having the unique privilege to host permanently or in migration, distinctive species of these three continents. After having the research questions, teachers collected the educational material, organized the work groups, implemented the didactic intervention in the classroom, had the field sampling of plants, recognized the synchronous local and scientific names of the plants, constructed the botany book, photographed the collected organisms and all the concentrated material was delivered to the team members.

-lyperspectral Response： Key for Mapping Coral Rubber, .ive and Dead Corals

Measurement, data collection, and analyzing statistically the spectral response of different bottom types are all important steps in mapping shallow water bottom types with remote sensing. Five small islands in the Spermonde archipelago, South Sulawesi, in Indonesia, were selected to measure the reflectance spectral of benthic communities. The objective of this study was to determine optical properties of the live corals, dead corals covered with algae, coral rubber covered with algae, broken shell, sand, seagrass and macro algae. Pearson correlation coefficient and cluster analysis were used to determine spectral similarity in and among coral species based on spectral responses at observed wavelengths and to examine the similarities between the categories. Several benthic communities appear to be highly correlated with one another when the entire spectrum is considered, which may lead to classification errors. Porites meyeri, dead corals and coral rubber （〉 3 months ago） share a high degree of similarity in reflectance. The other coastal benthic communities are readily discriminated.

Single-handed Shooting Action in Basketball Teaching Techniques Biomechanical Analysis

Basketball shooting technique is the core technology. The shooting angle, basket entering angle, ball＇s rotation, aiming at point, exerting strength cooperatively with the whole body, and flicking the ball using index finger before it leaves from hand are the important factors to decide if the shooting techniques are reasonable and the successful shooting rate is high or not. In this paper, the theory of biomechanics is analyzed around basketball spin on the role of shooting, shooting aiming point selection diversity, difference and its impact on investment and basketball shooting rate.

The Various Description of Biodiversity in Compulsory Education Textbooks

We intend to establish how species diversity is dealt with, within the study of the ecosystem, in books for the 4th year of Compulsory Secondary Education, ESO （15-16 year-old students）. The analysis was carried out using a key issues dossier based on school science, which not only provides a description of reality, but also introduces a theoretical explanatory framework. Regarding species diversity, we focused on the descriptive approach, considering the link between diversity and trophic relationships, ecological succession and ecosystem stability through change, consequences for biodiversity of human activities and mechanisms to face such consequences; and on the explanatory perspective, which provides an interpretative answer for all the aspects previously mentioned. The findings drawn from textbooks show that biodiversity is linked both to the study of the ecosystem and to the impact of human societies on its maintenance. However, such study is particularly focused on the descriptive, rather than on the explanatory level. So, teachers should improve the study of biodiversity foresting a balance between descriptive and explanatory level.
