A genética é um assunto de elevada importância pelo conhecimento científco que pode proporcionar para a vida pessoal e acadêmica dos alunos. Portanto, ela é imprescindível na formação destes para que possam decidir acerca de assuntos que envolvem sua própria vida e a sociedade. Nessa perspectiva, os docentes precisam compreender como os alunos percebem a genética, o que acham das aulas, se eles atribuem alguma razão em aprender o assunto. Diante do exposto, o objetivo desta pesquisa foi verifcar quais as percepções que os estudantes do Ensino Médio apresentam sobre os conceitos fundamentais de genética e quais as difculdades apontadas por eles em aprender esses conceitos. A pesquisa foi realizada em uma escola da rede pública de Manaus/AM com duas turmas do Ensino Médio. Para a coleta de dados foram utilizadas múltiplas fontes como a observação direta, questionários e entrevistas. Para melhor analisar os dados coletados, foram elaboradas categorias relativas a cada etapa da pesquisa. Essas categorias foram desenvolvidas baseadas em todas as evidências, que foram anotadas em campo, a partir de observações, dos questionários e das entrevistas. Os dados obtidos foram analisados à luz da Análise Textual Discursiva. As conclusões apontam que, muitas vezes, o ensino em sala de aula prima apenas pela memorização de conceitos, perdendo assim a contextualização dos conteúdos. Nota-se que os alunos têm a percepção de que a genética é complexa e difícil a sua compreensão, devido ao vasto vocabulário que envolve a matéria. Uma das possibilidades de mudança desta situação foi a proposição de uma Aula Expositiva Dialogada, que é uma estratégia que vem sendo sugerida para superar o ensino tradicional, por promover a participação e o envolvimento dos alunos ao tema exposto.Palavras-chave: Ensino da Genética.

Therefore, it is indispensable in the formation of these so that they can decide on subjects that involve their own life and the society. From this perspective, teachers need to understand how students perceive genetics, what they think of the classes, if they attribute any reason to learning the subject. In view of the above, the objective of this research was to verify the perceptions that the High School students present about the fundamental genetics concepts and what difculties they pointed out in learning these concepts. The research was conducted in a public school in Manaus / AM with two high school classes. For data collection, multiple sources were used such as direct observation, questionnaires and interviews. To better analyze the data collected, categories related to each step of the research were elaborated. These categories were developed based on all the evidences that were recorded in the feld from our observations, from the questionnaires and the interviews. The obtained data were analyzed in light of the Discursive Textual Analysis. The conclusions show that teaching in the classroom often only requires the concepts memorization, thus losing the context of the contents. It was noted that students have the perception that genetics is complex and difcult to understand because of the vast vocabulary surrounding matter. One of the possibilities for changing this situation was the proposition of an Exposed Dialogue Class which is a strategy that was suggested to overcome traditional teaching, by promoting the participation and the involvement of the students in the exposed subject Keywords: Genetics Teaching.

Argumentation plays an important role in the development of science which is not just finding and presenting facts, but building arguments and considering them, and debating various explanations about phenomena. The research aimed to capture the consistency of argument by students on socioscientific issues of cloning. Students have chosen purposively with the subject of 170 high school students from three high schools in Bandung City, West Java, Indonesia. This research uses a case study approach with a descriptive analysis to analyze student test results of argumentation. The consistency of argument consists of claims and reasons itself. The result shows the pattern of agreeing and disagree about cloning in 3 topics; 1) human, 2) animal for Qurban purposes, 3) extinct animals. The higher consistency showed disagree in topics 1&2 about 56,47% and consistency of reason for each topic are 1)religion 40%, 2) religion 57,6% and 3) science 83,5%. Then, the consistency of agreeing for all topics is 2,35% and disagree is 14,71%. This provides that, consistency in argumentation between topics of cloning is based on the context of phenomena, which is greatly influenced by science, religion, and social norms. It needs to be implemented to improved students argumentation in schools.

The study deals with the developing interactive media for senior high school students. The objective of this study is to find out how to develop interactive media for better speaking skill of senior high school students. The research was conducted by using Research and Development (R&D). The subject of this research was 2016/2017 students of the eleventh grade of Class XI IPA4 in SMAN 1 Batang Kuis. The number of the students was 30 students. The data of this study was collected by using need analysis questionnaire and experts’ judgment. Need analysis questionnaire was calculated by using percentage to get the information of students’ need before developing interactive media. Experts’ judgment was calculated by using likert data, mean and criteria interval of expert judgment to know the validity of interactive media which has been developed. After the data analyzed, it was found that the experts’ judgment result was 4.80 which had a very good criteria interval.

In the world of K–12 education, the growing numbers of dropouts are a major concern. This article examines the dropout rates of Chinese and Vietnamese high school students. Using logistic regression analysis, this article examines the influence of ethnicity, gender, and socioeconomic status (SES) on dropout rates. The distinct contribution of this analysis lies within the intraethnic comparisons within the Asian American student population and its use of longitudinal data. The results of the study support existing research that gender and SES are related to dropout rates. Moreover, an interesting interaction between ethnicity and SES exists.
