Strategies for Teaching Chemistry at Medium Professional and Technological Level Present in Scientific Articles

Chemistry teaching is not such an easy task for teachers trained in contemporary times. The process of updating your resume should be a constant in the profession. The teacher needs to plan his classes with a language that can make it easier for the student to understand the contents explained. One of the ways of working with chemistry could be with the student actively participating in the process. Agrochemicals are feasible topics to be mediated in this way and can potentially increase students’ interest in the discipline. This article aims to identify the strategies for teaching chemistry at a high professional and technological level present in scientific articles with the theme “pesticides”. The methodology chosen for this study was a qualitative approach centered on being concerned with reality. The observation of this brief survey allows us to conclude that the teaching of chemistry in high school groups can and must be related to the area of research and scientific dissemination; there are several didactic tools that enable more assertive ways related to teaching chemistry; and relating the content of chemistry to interdisciplinary and specific subjects, such as pesticides, can help a better understanding of the content of chemistry in high school students.

Resumo: Esta pesquisa tem por objetivo analisar quais são as contradições presentes nas percepções dos estudantes do terceiro ano do Ensino Médio de uma escola situada no município de Campo Verde - MT, sobre os agrotóxicos e sua relação com o meio ambiente, a saúde humana e a Química. Adotou-se uma abordagem qualitativa, cujo percurso metodológico consistiu na aplicação de um questionário e análise textual discursiva do mesmo. Os agrotóxicos fazem parte do cotidiano dos estudantes residentes no município, cuja base econômica é a agricultura. Como resultado se percebe que os estudantes apresentam um nível de conhecimento prévio satisfatório sobre os agrotóxicos, embora haja muitas contradições em suas percepções e o tema não esteja presente na maioria dos livros didáticos. Portanto, é necessário realizar processos de informação e sensibilização quanto aos aspectos atitudinais e aos conhecimentos científicos, considerando a abordagem CTSA, o contexto dos estudantes e o tema controverso que envolve os agrotóxicos.Palavras-chave: Agrotóxicos; Contradição; CTSA; Ensino de Química. Abstract: This research aims to analyze what are the contradictions present in the perceptions of third year high school students of a school located in the municipality of Campo Verde - MT, pesticides and their relationship with the environment, human health and Chemistry. A qualitative approach was adopted, whose methodological path consisted of the application of a questionnaire and discursive textual analysis of the same. Pesticides are part of the daily lives of students residing in the municipality, whose economic base is agriculture. As a result, it was noticed that students have a satisfactory level of prior knowledge about pesticides, although there are many contradictions in their perceptions and the theme is not present in most textbooks. Therefore, it is necessary to carry out information and awareness processes regarding attitudinal aspects and scientific knowledge, considering the CTSA approach, the students' context and the controversial topic involving pesticides.Keywords: Pesticides; Contradiction; CTSA; Chemistry teaching.

Therefore, the nature of a child is completely passed on by the mother. A mother's love and concern greatly affect a child's self-confidence. The mother communicates with her child so that the child feels happy and comfortable. This research uses a qualitative approach. Data collection techniques by means of semi-structured interviews with mothers and children who are high school students.

Oleh karena itu, sifat seorang anak sepenuhnya diturunkan oleh ibu. Kasih sayang dan rasa perhatian seorang ibu sangat mempengaruhi rasa percaya diri anak. Ibu berkomunikasi pada anaknya agar anak merasa senang dan nyaman. Penelitian ini menggunakan pendekatan kualitatif. Teknik pengumpulan data dengan cara wawancara semiterstruktur pada ibu dan anak yang merupakan siswa SMA. Penelitian ini menunjukkan bahwa, kedekatan antara anak dan ibu tidak ditentukan oleh jenis kelamin. Ibu memiliki peran krusial dalam membuat anak tampil percaya diri. Caranya dengan mengingatkan anak untuk menjadi diri sendiri, mendukung hobi anak, mengajak berkomunikasi secara intensif, menegur tanpa kekerasan, serta menciptakan suasana yang nyaman di rumah.

The chemistry teaching at Vocational High School which tends to be theoretical and not directly connected to vocational lesson has caused students to have low interest, low motivation, and low achievement. The problem is becoming more complex due to limited time allotment and limited teaching materials. One of the efforts to solve the problem is by providing the relevant teaching material using contextual learning approach. The aims of this Research and Development (R&D) research are: (1) to produce an appropriate chemistry teaching material on electrochemistry integrated with skill program subjects using Contextual approach for Vocational High School students of Machinery Engineering Department; (2) to know the feasibility of development result of teaching material. The development of the teaching material uses 4D developmental model from Thiagarajan et al consisting of four phases namely Define, Design, Develop, and Desiminate. The dominate phase was not done. The scores of evaluation of the feasibility or the appropriateness of the product from the content expert are 88.75% (very feasible) for the teachers’ book and 91.25% (very feasible) for the students’ book. The expert on media gave 89.25% (very feasible) for the teachers’ book and 89.9% (very feasible) for the students’ book. The result of readability test shows that the teachers’ book is feasible (83.81%) and the students’ book is very feasible (93.61%).Keywords: Teaching material on electrochemistry, Machinery Engineering Department of Vocational High School, Contextual Approach

The City

New technologies in education have brought challenges to the educational environment for the school and, above all, for the teacher's practice outside and within the classroom, as it now requires a new profile of educator who is no longer one who only exposes content and after demanding the results in the assessments, the teacher must have the role of mediator between the student and knowledge. Starting from this initial position, this paper seeks to analyze the challenges faced by the school and the teachers to insert and work with the student in the world of new technologies, while trying to identify the problems faced by teachers in the context of the classroom and the challenges to insert the student in the use of new technologies. The methodology used was a bibliographical research combined with a field research, starting from a quantitative and qualitative approach with students and teachers on the use of these resources in the classroom. The research had the participation of thirty-two first-year high school students and ten teachers from different areas of knowledge, from the Monsenhor Vicente Freitas State High School, located in the city of Pombal in the State of Paraíba. The main authors who contributed with important reflections for the construction of this work were: FREIRE, GADOTI and KENSKI.
