The Effect of Cooperative Learning on Students’ Achievement and Views on the Science and Technology Course

The Effect of Cooperative Learning on Students’ Achievement and Views on the Science and Technology Course

In the study, the disadvantage of the practice was found out to be the requirement to be successful for all group members. This situation is stated in two ways. First one is the anxiety of less successful students due to the group pressure. "I studied hard in order not to be unsuccessful in the tournament. But I could not answer the question twice, because I was excited. My group got angry with me. Yet, if I were unsuccessful in an exam, nobody would get angry with me (S9). The other kind of anxiety is the anxiety of successful students to be unsuccessful because of the less successful members of the group. "I would like successful students to be in my group. Even if I were successful, I would become unsuccessful if they were not successful (S7)" Both of these reasons caused students to have unfavorable feelings. These results might be due to the characteristics of the study group. The mentioned group consists of students who got into the private school through scholarship exams with high academic success and their teachers and parents consider academic success among priorities. Therefore, students are inclined to eliminate the unfavorable factors affecting their success. Hence, the success of the students in this process was appreciated and in case of not being successful they stated that they were faced with isolation in the group and were scolded. Moreover, in order not to be isolated from the group and face with negative attitudes, they studied hard and saw these factors as favorable pressure items: "Not only our instructor but also our friends got angry with us" . This also created anxiety in case of not being successful: "I wanted to be successful in order not to be excluded from the group and being scolded. Especially, I studied hard in order not to be unsuccessful in the tournament but my anxiety was very high (S2)".

Difficulties of Pre-service Teachers in Developing and Implementing Teaching Activities Based on 5E Model in Constructivist Approach

Difficulties of Pre-service Teachers in Developing and Implementing Teaching Activities Based on 5E Model in Constructivist Approach

Abstract - This study aimed to determine difficulties of student teachers in developing and implementing teaching activities based on 5E model in constructivist approach. Thus, it was carried out in the context of Science Teaching II practices course in spring semester of 2007-2008 academic year. The sample group of the study consisted of 25 junior student-teachers at the Department of Classroom Teacher Education in Faculty of Education at Artvin Çoruh University. In the study, a qualitative research design was used, and it was implemented in three steps. In the first step, the pre-service teachers were given standards which were about fifth class Science and Technology course; then, they were asked to prepare an activity appropriate for 5E model. In the second step, they were asked to carry out those activities, and observations were carried out by one of the researchers. In the last step, semi-structured interviews were carried out with them. In the result of the study, the following problems were determined. The student-teachers were unable to use time effectively, to provide the classroom’s discipline, to apply the stage of the 5E model, to relate the concepts with daily life situation, to know how to evaluate appropriately and to attract attention of students.

Computational modelling in science, technology, engineering and mathematics education

Computational modelling in science, technology, engineering and mathematics education

The 2009 edition of the general physics course for biomedical engineering involved a total of 115 students. Of these, 59 were taking the course for the first time and only they were enrolled in the computational modelling classes. To build an interactive collaborative learning environment, we organized the students in groups of two or three, one group for each computer in the classroom. During each class, the student teams worked on a computational modelling activity set conceived by us to be an interactive and exploratory learning experience with Modellus, built around a small number of problems in mechanics connected with easily observed real world phenom- ena. The teams were instructed to analyse and discuss the problems on their own using the physical, mathematical and computational modelling guidelines provided by the activity set documentation, a set of PDF documents with embedded video support. To ensure a good working pace with appropriate conceptual, analytical and computational understanding, the students were continuously monitored and helped during the exploration of the activities. Whenever it was felt necessary, global class discussions were conducted to clarify doubts on concepts, reasoning or calculations. Online support in class and at home was provided in the context of the Moodle platform where links to class and home work documentation was provided.

Reflection of an In-service Education Course Programme for Science and Technology Teachers about Alternative Measurement and Assessment Techniques: Trabzon Sample

Reflection of an In-service Education Course Programme for Science and Technology Teachers about Alternative Measurement and Assessment Techniques: Trabzon Sample

Abstract- The aim of this study is to investigate the effectiveness of an in-service education course program including alternative measurement and assessment techniques on participant teachers’ skills and perspectives. Case study was used in this study. The sample of the study consisted of six voluntary science and technology teachers working in Trabzon. Researcher’s diary, document analysis and semi-structured interviews were used for data collection. Qualitative data analysis was used in this study. Holistic rubric prepared by researcher was used for document analysis. Matris forms including codes were used for interviews analysis. At the end of the study, it was concluded that in-service education course program had positive effects on teachers’ skills and their perspectives of using alternative assessment techniques in their lessons. In addition, teachers had difficulty in preparing analytic rubrics during the in-service education course period. Recommendations were presented on the arrangement of in-service education course program which include lots of activities and may contribute teachers’ skills using alternative assessment techniques

Food science and technology students self-evaluate soft and technical skills

Food science and technology students self-evaluate soft and technical skills

From May through November 2012, 267 ques- tionnaires were collected from students (Table 2). All responding students answered all ques- tions and there were no missing data. Responses came from over 21 countries and these were or- ganized into 4 geographical regions. Northern and Southern Europe were well represented, with 71% of the responses coming from these two re- gions, likely due to the higher level of participa- tion of higher education institutes in these coun- tries in the ISEKI Food 4 project. Nonetheless, the geographical spread of respondents gives a good sample of food science students, with the exception of a lack of representation from Africa. Respondents were equally divided between un- dergrads, that is those working towards a tech- nical or Bachelor degree, and postgrads, that is those working towards a Master or Ph.D. A large majority of the students, 85%, expected to even- tually earn a postgraduate degree. This may in- dicate a trend towards growing professionalism in food science and technology. A recent study showed most employees with a university degree in food science had a Bachelor (Flynn, Ruiz- Bejarano, et al., 2013) while a later study, in which 75% of respondents were under 40 years old, showed equal numbers with a Bachelor and with a Master degree (Mayor et al., 2015), and here, most current students expect either a Mas- ter or a Ph.D. degree. Of course, what a person expects and what actually occurs may not be the same. Currently, the Bachelor and Master de- grees are leading not only to different knowledge and skills but also to different specialisations within the broad area of Food Science and Tech- nology disciplines. Only future surveys can con- firm if FS&Ts are truly trending towards higher levels of education.

Application of a Bibliometric Tool for Studying Space Technology Trends

Application of a Bibliometric Tool for Studying Space Technology Trends

This study shows that bibliometric analysis is an appropriate tool for predicting trends in space technologies, allowing to identify the mostly used keywords and research fronts in scientific publications, contributing then for the technological monitoring of the space sector. The present bibliometric study indicates a great interest on the development and utilization of small satellites in space applications, including remote sensing constellations and technology demonstrations, probably as a result of the improved functionality through the miniaturization of technology and alternative philosophies of conception, reducing costs and development time, and increasing space accessibility for scientific purposes, enabling new forms of space exploration.

METRICS FOR SCIENCE AND TECHNOLOGY AND RESEARCH FUNDING: reflections on evaluation

METRICS FOR SCIENCE AND TECHNOLOGY AND RESEARCH FUNDING: reflections on evaluation

Indicadores econômicos e sociais, externos à literatura científica, são também utilizados por vários países para medir a ciência, mas também para esses há críticas e restrições. Kondo (1998), por exemplo, adverte para a necessidade da adaptação dos indicadores internacionais às condições específicas do país, especialmente tratando-se de países não pertencentes à Organization for Economic Cooperation and Development (OCDE), que é, segundo o autor, a principal fonte de referência desses indicadores. Em seu artigo, Kondo propõe novo marco conceitual que inclui considerações relacionadas ao bem estar social, além da eficiência econômica, antecipando em alguns anos o novo indicador de cunho social, proposto recentemente pela CAPES, citado acima (RIBEIRO, 2007). Reforçando a visão de Kondo ao citar a OECD como principal referência para indicadores econômicos da ciência, Geisler (1999, p.48-49) comenta que as primeiras tentativas de construção de indicadores padronizados para ciência partiram da OECD em 1963 (Manual Frascati) e da United Nations Educational Scientific and Cultural Organization – UNESCO em 1968. Ainda com referência aos indicadores econômicos propostos pela OECD, Leydesdorff (2005) considera que as circunstâncias em que foram elaborados explica sua emergência como uma resposta “à importância crescente da ciência e tecnologia que se tornou visível nas estatísticas econômicas da década de 1950”.

The development of relationships in science, technology, research and innovation in health between the EU and LAC countries: a promising future :: Brapci ::

Two relevant SOM in the field of S&T were organized following the Rio Summit and as groundwork to the next Heads of State Summit scheduled to take place in Madrid in 2002 - the first one took place in Lisbon on June 2000 and the second in Bruges on December 2001. Their objective was to establish a political dialogue in S&T and to promote joint research and technological development to benefit the sustainable and equitable development of both regions. There was recognition of the need to develop a common vision for bi-regional cooperation. Six priority areas of cooperation were agreed: promoting healthy societies and life quality; information society; competitive growth in the global environment; sustainable development and urbanization; cultural, crosscutting issues – including human resource development, intellectual property rights, and ethical issues 2 .

Scientific illiteracy and the partisan takeover of biology.

Scientific illiteracy and the partisan takeover of biology.

Miller has devoted his 30-year career to studying public understanding of science and technology and its implications for a healthy democracy. To possess what Miller calls civic scientifi c literacy, one must have the capacity to make sense of competing arguments in a scientifi c debate. Over the year leading up to the 2004 US election, Miller polled a national panel of adults to track their grasp of the ongoing debate about stem-cell research. A year before the election, over a third of adult respondents had never heard the term, even though the issue had dominated the headlines. By the eve of the election, only a few more respondents said they had heard about stem cells. How could so many people manage to remain oblivious to one of the most contentious issues of the election?

Data about science and pseudoscience reveal that many people maintain belief in phenomena that exist outside the scientific paradigm. Although the vast majority of Americans report that they value science and technology, belief in what the National Science Foundation describes as pseudoscience is comparatively strong. A variety of phenomena fall within the definition of pseudoscience. More than 25% of the public in the United States affirmatively believes in astrology, and 18% is not sure whether they believe in it or not. 41% of the public describe astrology as scientific in nature. Between 50 and 60% of the American public believes in extrasensory perception. Between 30 and 33% of the public believes that sentient extraterrestrial beings have landed on Earth at some point in its history, and various surveys have found that between one-quarter and one-half of the population believes in some other form of pseudoscience – ghosts, haunted houses, lucky numbers, etc. Perhaps most striking, belief in most areas of pseudoscience has grown over the past decade.

Metaversia: a mooc model for higher education

Metaversia: a mooc model for higher education

Brown & Adler (2008) say that mastering a field of knowledge involves not only “learning about” the subject matter but also “learning to be” a full participant in that field. This mastery in- volves acculturating into a community of practice. Historically, apprenticeship programs have provided students with opportunities to observe and then to emulate how experts function. Stu- dents start by learning by taking on simple tasks, under the watchful eye of a master, through a process that has been described as “legitimate peripheral participation” and then then progress to more demanding tasks as their skills improve. A contemporary model that exemplifies the power of this type of social learning is provided by the networked communities of practice in which people work together voluntarily to develop and maintain open source software like Linux or Apache or contributing to Wikipedia. In these open environments, both the content and the pro- cess by which it is created are equally visible, enabling a new kind of critical reading—that in- vites the reader to join in the consideration of what information is reliable and/or important (Brown & Adler, 2008). The tools that have emerged from the Web 2.0 such as blogs, wikis, so- cial networks, tagging systems, mashups, and content-sharing sites are examples of a new non- professional user-centric information infrastructure that emphasizes participation (e.g., creating, re-mixing) over presentation, encouraging focused conversation and the formation of an under- standing that emerges from action, not passivity (Brown & Adler, 2008).

What can the philosophy of science contribute to the ethics of science and technology?

What can the philosophy of science contribute to the ethics of science and technology?

Perhaps the most important argument, how- ever, concerns the potential gains arising from public involvement in the management of technoscience. The consideration upon the desirability of strictly objective evaluations (if indeed they are possible) indicates that the subjectivity might be capable of contributing to the evaluation by plural committees, so as to eventually achieve more satisfactory results. Although the participation of laymen adds cer- tain financial costs to the decision-making process, scientific knowledge, as relevant as it may be con- sidered, remains instrumental. Its relevance derives from its significant contribution to solving the most diverse problems, but from a moral standpoint it remains an instrument which should be used only in appropriate circumstances. Of equal importance to instrumental knowledge is speculative knowl- edge, which makes significant contributions to our understanding of the moral scenario, so that social participation will give the decision-making process a real chance of maximizing the desirable benefits and minimizing the undesirable risks.

The research analyzes the effect of the microbiological inoculant in silage of elephant (Pennisetum purpureum cv. Purple) in increasing concentrations of inclusion. The experiment was conducted at the Department of Zootecnia (Animal Science), Universidade Federal Rural da Amazônia (UFRA) consisted of four replications and five treatments (Control, LP/PC4, LP/PC5, LP/PC55, LP/PC6) who were in plastic buckets with lids and sealed with plastic tape, which were weighed weekly until the end of the experiment. Were carried out chemical and bromatological analysis of forage and silages in samples at the opening (Day 0) and the last day of aerobic stabilization (Day 10), beyond the counting of fungi and yeasts in silages to evaluate the quality of the ensiled material. During aerobic data loggers were placed in silos to observe the temperature in the post fermentation There was no significant difference in the chemical composition of silages and mold counts, dry matter recovery, but there was no difference in yeast count at the time of opening. Treatment of higher dosage of the inoculant took more time to break aerobic stability when compared with the control. The use of Lactobacillus plantarum and Pediococcus acidilactici can be recommended, since it improves the stability, but in terms of fermentation and chemical composition, the effects were minimal.
