The present study attempts to identify the difficulties of teaching and learning geology in Moroccan secondary qualifying classes. Teachers of the Life Sciences and Earth Sciences and their pupils at the Inzegane Ait Melloul delegation were administered questionnaires. Based on the analysis of the themes taught and the typologies of obstacles evoked, a bibliographic synthesis allowed us to list the notions which are likely to pose the difficulties presumed in geology. Thus, 23 open and closed questions were distributed to seven teachers. Also, ten questions were distributed to students. The results showed that both pupils and teachers experience several difficulties in the teaching and learning of geology. Thus, the various means of continuing education in geology which are made available to teachers were disqualified. It involves only a minority of them. This is in addition to the complexity of the geological content and the insufficiency of its hourly volume. The excessive number of pupils causes the classes to be overloaded, in which the weak prerequisite is added in the geology of these pupils. The difficulties of learning geology are largely related to the relationship that this discipline maintains with space and long time. This, therefore, make it difficult for pupils to understand several complex geological phenomena. The ineffectiveness of teaching methods tailored to the classroom by teachers, the absence, failure or lack of mobilization of teaching and ICT resources, inadequacy or absence of field trips, and the manipulations and negligence of scientific modeling in majority of the classes surveyed influences the learning of geology as well as the students' interest in these courses. This makes it a boring and unwelcome matter for most students.

Brazilian Science

Despite significant progress, there is still a gender gap in science all over the world, especially at senior levels. Some progressive countries are recognizing the need to address barriers to gender equality in order to retain their best scientists and innovators, and ensure research excellence and social and economic returns on the investment made by taxpayers each year on training women scientists. We investigated the gender distribution of: (i) the productivity scholarship (PS) holders of the Brazilian National Council for Scientific and Technological Development (Conselho Nacional de Desenvolvimento Científico e Tecnológico, CNPq,N= 13,625), (ii) the members of the Brazilian Academy of Science (Academia Brasileira de Ciências, ABC,N= 899), and (iii) the amount of funding awarded for top quality research (“Universal” Call of CNPq,N= 3,836), between the years of 2013 and 2014. Our findings show evidence for gender imbalances in all the studied indicators of Brazilian science. We found that female scientists were more often represented among PS holders at the lower levels of the research ranking system (2). By contrast, male scientists were more often found at higher levels (1A and 1B) of PS holders, indicating the top scientific achievement, both in “Engineering, Exact Sciences, Earth Sciences”, and “Life Sciences”. This imbalance was not found in Humanities and Social Sciences. Only 14% of the ABC members were women. Humanities and Applied Social Sciences had a relatively low representation of women in the Academy (3.7%) compared to Engineering, Exact and Earth Sciences: 54.9% and Life Sciences: 41.4%. Finally, female scientists obtained significantly more funding at the lower level of the research ranking system (2), whereas male scientists obtained significantly more funding at the higher levels (1A and 1B). Our results show strong evidence of a gender imbalance in Brazilian science. We hope that our findings will be used to stimulate reforms that will result in greater equality in Brazilian science, and elsewhere.

: Nanoalloy clusters has attracted a lot of attention in recent times and it is growing enormously in various domains, ranging from semiconductor, material sciences, bio-physics, life sciences to earth sciences. In this report, we have presented a review on nanoalloy clusters and its application. The background of clusters, nanoalloys and its isomers, classification, potential applications from catalysis, optoelectronics, magnetic to bio-diagnosis is reported. Experimental techniques as well as importance of theoretical and computational studies in nanoalloy clusters is also presented.

Seven British Antarctic Survey stations were operational during the year. However, in March 19755 Stonington Island was closed after 21 years of occupation. A number of senior Survey staff visited the bases this season, including Dr R. J. Adie (Deputy Director), Dr C. Swithinbank (Head of Earth Sciences), Mr W. N. Bonner (Head of Life Sciences), Dr J. Dudeney (Leader of the Ionospherics Section), and Mr W. Sloman (Head of Administration).
