An analysis of Brazilian federal expenditures in science and technology is presented is this study. The 1990-1999 data were compiled from records provided by two federal agencies (MCT and CNPq) responsible for managing most of the national budget related to these activities. The results indicate that the federal investments in Brazilian science and technology stagnated during the last decade (US$ 2.32 billion in 1990, US$ 2.39 billion in 1996, and US$ 2.36 billion in 1999). In contrast, a great increase in private investments in research was acknowledged both by industry and by the government during the same period, from US$ 2.12 to US$ 4.64 billion. However, this investment did not result in an increase in invention patents granted to residents (492 in 1990 and only 232 in 1997) or in a reduction of patent costs. Despite this unfavorable scenario, the number of graduate programs in the country has increased two-fold in the last decade and the contribution of Brazilians to the database of the Institute for Scientific Information has increased 4.7-fold from 1990 (2,725 scientific publications) to 2000 (12,686 scientific publications). Unstable federal resources for science, together with the poor returns of private resources in terms of developing new technologies, may jeopardize the future of Brazilian technological development.

The quantitative component of this study examined the effect of computerassisted instruction (CAI) on science problem-solving performance, as well as the significance of logical reasoning ability to this relationship. I had the dual role of researcher and teacher, as I conducted the study with 84 grade seven students to whom I simultaneously taught science on a rotary-basis. A two-treatment research design using this sample of convenience allowed for a comparison between the problem-solving performance of a CAI treatment group (n = 46) versus a laboratory-based control group (n = 38). Science problem-solving performance was measured by a pretest and posttest that I developed for this study. The validity of these tests was addressed through critical discussions with faculty members, colleagues, as well as through feedback gained in a pilot study. High reliability was revealed between the pretest and the posttest; in this way, students who tended to score high on the pretest also tended to score high on the posttest. Interrater reliability was found to be high for 30 randomly-selected test responses which were scored independently by two raters (i.e., myself and my faculty advisor). Results indicated that the form of computer-assisted instruction (CAI) used in this study did not significantly improve students' problem-solving performance. Logical reasoning ability was measured by an abbreviated version of the Group Assessment of Lx)gical Thinking (GALT). Logical reasoning ability was found to be correlated to problem-solving performance in that, students with high logical reasoning ability tended to do better on the problem-solving tests and vice versa. However, no significant difference was observed in problem-solving improvement, in the laboratory-based instruction group versus the CAI group, for students varying in level of logical reasoning ability.Insignificant trends were noted in results obtained from students of high logical reasoning ability, but require further study. It was acknowledged that conclusions drawn from the quantitative component of this study were limited, as further modifications of the tests were recommended, as well as the use of a larger sample size. The purpose of the qualitative component of the study was to provide a detailed description ofmy thesis research process as a Brock University Master of Education student. My research journal notes served as the data base for open coding analysis. This analysis revealed six main themes which best described my research experience: research interests, practical considerations, research design, research analysis, development of the problem-solving tests, and scoring scheme development. These important areas ofmy thesis research experience were recounted in the form of a personal narrative. It was noted that the research process was a form of problem solving in itself, as I made use of several problem-solving strategies to achieve desired thesis outcomes.

A sample of 1,345 students enrolled in advanced-level science courses from Grades 9 through OAe was surveyed in order to gain perspective into the existence of motivational differences attributing to science course enrolment by gender. Records of enrolment were examined in order to detect patterns and trends. A questionnaire was devised and piloted. It measured five motivational variables - demographics, science and science-related experiences, science ability and attitudes, impressions about women in science, and importance of science and science-related skills. The students also provided some impressions about the image of scientists. Results of the questionnaire were analyzed for frequency of responses and for significant gender differences using the chi-square. Differences were found to exist in the areas of science anxiety as it relates to testing and oral participation; in motivation generated by the performance of extra-curricular science and science-related activities, and by the classroom environment; in impressions of women in science; in the importance of science skills, and in the area of teacher influence. The study also showed a differential enrolment of females, with an emphasis on biology and chemistry. The males were enrolled in courses of physics and chemistry. The findings lead to numerous suggested strategies and programs for encouraging the participation of females in science education and careers.

This paper describes the current information dynamics and its effect in higher education and research in science and technology. Open access movement ,Institutional repositories ,Digital libraries,Knowledge gateways,Blogs,Wikis,and social bookmark tools have rapidly emerged on the web creating a new scenerio that radically changes the knowledge production process such as the creation of information,formats and sources of information,coding and processing ,accessing managing sharing and dissemination of information.The management of knowledge created by academia of Cochin University Of Science And Technology is examined in this challenging context of information dynamics.

Esta investigación pretende, por un lado, describir y explicar los rasgos orales de las redacciones de los estudiantes españoles de inglés como lengua extranjera; y, por otro, intentar mejorar el estilo escrito de los textos de estos estudiantes a través de una intervención pedagógica.. Se diseña y aplica un tratamiento pedagógico a un grupo de estudiantes de segundo de bachillerato de Madrid. La instrucción se centra en hacerles conscientes de los recursos lingüísticos disponibles en inglés para la redacción de un texto. Se comparan las composiciones escritas por los estudiantes antes del tratamiento experimental con sus producciones posteriores, así como con un grupo de control del mismo instituto que no recibe ninguna instrucción. Se cotejan los textos en inglés con redacciones escritas en español por los estudiantes del grupo experimental. Asimismo, los textos escritos en inglés después del tratamiento experimental se comparan con redacciones de un grupo de estudiantes nativos de secundaria. Se analizan dos variables, para las que el estudio aporta sendos instrumentos de medida, la calidad y el grado de estilo escrito de los textos. La comparación de los textos escritos en español y en inglés de los estudiantes españoles del grupo experimental revela que las redacciones en la lengua materna son superiores en relación a su calidad pero no al grado de estilo escrito. Varios resultados estadísticos apuntan que el tratamiento recibido por el grupo experimental contribuye al desarrollo del grado de estilo escrito de los textos en inglés pero no mejora la calidad global de los mismos. Los resultados revelan que el grupo experimental es similar a los nativos en el grado de estilo escrito, aunque éste último supera a los estudiantes del inglés como lengua extranjera en la 'calidad' de los textos. Este estudio concluye que la impronta oral de las redacciones de los estudiantes de inglés como lengua extranjera puede deberse a la combinación de varios factores, la competencia discursiva en la lengua materna, la competencia lingüística/discursiva en la lengua objeto de aprendizaje, el conocimiento socio-cultural y lingüístico de adecuación contextual y el tipo de pedagogía en inglés como lengua extranjera.
