The Internship is a process that enables the future teacher, among other skills, to use technologies associated with Education such as Virtual Learning Objects (VLOs). In the supervised internship carried out by the author, an OVA site was developed, focused on the difficulties in Genetics, Evolution and Ecology pointed out by 3rd year students from a peripheral public school, with the objective of helping their doubts and promoting the access to different types of teaching-learning methodologies and approaches in a context of social and economic vulnerability. The methodological path consisted of: the meeting of the greatest difficulties to guide the construction of the site; elaboration of the content to be mediated through the site; development of the hypertext structure by means of tools and computer programs; three hours/classes to apply theoretical explanations, examples, images and a simulator; and evaluation. It was inferred that the use of OVA's, when concerned and guided by the needs of students, triggers greater interest reflected in greater participation, generating better learning of content. It was also remarkable the development of cognitive skills extremely necessary to live in a digitalized world as the current moment, in addition to developing fundamental skills for citizenship.

This study aimed to analyze which learning theories biology teachers from Surubim / PE know and apply in the classroom. Ten biology teachers who work in the state school system participated in the study. The research was exploratory, qualitative approach. In the data collection, semi-structured interviews with personal questions and questions related to the research objectives were used. For data analysis was followed the proposal of the hermeneutic-dialectical method according to Minayo (1992). The results showed that biology teachers had a fragmented knowledge about learning theories, and this may have been caused by the lack of interest in the pedagogical subjects during their initial formation.

El objetivo fue comprender la importancia de dos tubérculos andinos orgánicos como Oxalis tuberosa Molina y Ullucus tuberosus Caldas, en cuanto a sus componentes benéficos para la salud humana, así como darle un valor agregado mediante una técnica ancestral, llamada comúnmente “chuño”, conocidos como caya y chullce en la región Huancavelica. Se revisaron bases de datos Science direct, Taylor & Francis, Wiley, PubMed, Scielo y Alicia, con una antigüedad de 20 años. Los resultados más relevantes se sistematizaron en tablas y se analizaron para resaltar las cualidades que ambos tubérculos tienen como producto fresco y, las posibilidades que puedan tener al convertirlos en productos agroindustriales que retienen sus propiedades funcionales.

El fenómeno actual que vive la humanidad, conlleva virar seriamente al escenario de la investigación científica. Aspecto fundamental que genera alternativas de solución a los avatares de la naturaleza que afrontamos en la convivencia humana. La investigación en el Perú y en otras partes del mundo, fue rezagada por situaciones suntuarias de lo efímero de la satisfacción inmediata. Las consecuencias para afrontar las epidemias y problemas sociales se evidencian en la salud pública y el caos social que se genera a falta de alternativas de investigación social.

O objetivo era compreender o uso e a importância dos marcadores genéticos utilizados nos estudos da diversidade genética na batata. As publicações mais relevantes dos últimos vinte anos no SciELO, LILACS e PUBMED foram revistas, examinando a técnica utilizada, os principais resultados obtidos com o uso e evolução das principais metodologias de marcação nos últimos anos e um melhor entendimento das técnicas mais utilizadas, concluindo que as cultivares de batata são discriminadas com maior precisão com marcadores baseados em DNA, já que os marcadores baseados em proteínas não as discriminam em sua totalidade.

We understand that the Biological Evolution is the set of processes of modifications in hereditary characters that has transformed the life on Earth, promoting the diversity of existing organisms. PCN and OCEM propose an ecological-evolutionary approach of the content in Biology. However, this is not adequately approached. This work aimed to evaluate the conceptions of 3rd. High School grade, in a public school, to promote the diffusion of critical-scientific knowledge about this theme. Educational intervention was carried out and, after this intervention, another activity was applied, and was possible to notice that the students answers were based more in the scientific knowledge. Finally, we identified some challenges about to work this knowledge with an integrative approach

Considering the relevance of discussions focused on Food and Nutritional Education (EAN), the objective of this work was to investigate the productionsr related to healthy eating in school curriculum bias, teacher training and didactic strategies in Science / Biology Teaching. To this end, a literature review was carried out in the editions of the National Meeting on Teaching Biology and the Journal of Teaching Biology, given their role in discussions in the field of Natural Sciences. Of the forty articles identified, there were publications focused on the school curriculum (1), teacher training (11) and didactic strategies (28), referring to EAN in different contexts. Thus, this theme has been discussed in science education, providing better training for school subjects - undergraduates, teachers and students.

This study aims to understand which norms and standards regulate the science curriculum of the first three years of elementary school using children's literature books. The curriculum is understood as socially and historically constructed due to disputes in disciplinary communities, which result in the valuation of certain forms of knowledge. Books are conceived as school objects that carry traces of school culture. Methodologically, four teachers’ interviews and two children's literature books are analyzed. The results have indicated that the use of these objects is linked to subversive practices, revealing the inventive nature of teaching activities to articulate literary texts and the Science curriculum.

The study of nutrition and energy metabolism in high school depends on a series of concepts of organic chemistry, which will only be worked on in the last year by the Chemistry professor. The great difficulty for Biology teachers is to introduce these chemical concepts in parallel to this content. We believe that only the lectures are not enough to arouse the interest of students. Based on this premise, we believe that the development of new educational materials is very relevant to improve learning. “Survival” is an investigative / cooperative board game on nutrition and energy metabolism. Used as a playful strategy, it was developed as teaching material to assist teachers in reviewing concepts on the topic.

There are many transgenic products in everyday life. In addition, it is common to have debates on the topic in the media, often without technical support. Bearing in mind that students have access to the media and that they can influence the construction of their knowledge, this work aimed to carry out a textual discourse analysis on this topic in the educational websites of Biology. The results show that the concept of the term has errors, the explanation of transgenics is fragile and there are few examples. The lack of scientific basis may contribute to a critical view of transgenics, or to facilitate the manipulation of opinions.
