Photosynthesis is challenging for teachers to instruct, both among younger and older students. Students find it difficult to comprehend its chemical and biological significance for plants and ecosystems. Additionally, it is challenging to make the teaching of photosynthesis relevant and useful for students, ena-bling them to understand and engage with issues related to their everyday life and society. The purpose of this study is to exemplify how organizing purposes can be used as a support for professional experimentation to address didactic questions in one's own practice, concerning how teaching can make photosynthesis knowledge powerful for primary school students. A didactic modeling was conducted with a qualitative research approach inspired by action research, to demonstrate how the model of organizing purposes can support teachers in planning, implementing, and evaluating teaching that promotes students' pow-erful knowledge in photosynthesis. To illustrate the supportive role of organizing purposes in didactic analysis and teaching design, we conducted two complete lessons and initiated a third one. Data were collected through video recording so that the design could be evaluated, analyzed and transcribed. The teaching was conducted in a fifth-grade classroom, with a total of fourteen stu-dents participating. The instruction consisted of chemical concepts and explan-atory models, the chemical processes in photosynthesis, combustion and cellular respiration, and finally, photosynthesis related to the chemical reactions occurring in animals and plants.The results exemplify how the model of organizing purposes provided support for the planning, implementation, and evaluation of the content of the lessons. In the analysis, the conceptual framework supported improvements in the teaching design. The model guided the instruction towards continuity and pro-gression and enabled clear reflection and revision of the content. One conclu-sion of the study is that exemplification demonstrates how organizing purposes can serve as a support for reflecting on how to adapt and combine the teacher’s overarching goals with the instruction, bridging to the more student-centered immediate purpose. Therefore, it is a didactic tool that can assist teachers in creating photosynthesis instruction that is relevant and interesting for students and, in many ways, enable their scientific knowledge to become powerful. / Fotosyntesen är svår för lärare att undervisa om, både bland yngre och äldre elever. Eleverna har svårt att förstå dess kemiska och biologiska betydelse för växter och ekosystem. Dessutom är det svårt att göra fotosyntesundervisningen relevant och användbar för eleverna, så att de kan förstå och agera i frågor som rör vardagslivet och samhället.Syftet med studien är att exemplifiera hur organiserande syften kan användas som stöd för professionell experimentering för att adressera didaktiska frågor i den egna praktiken, kring hur undervisning kan göra fotosynteskunskaper kraftfulla för elever i mellanstadiet. En didaktisk modellering har gjorts med en kvalitativ forskningsansats med aktionsforskning som inspiration, för att visa hur modellen organiserande syften kan stödja lärare i planering, genomförande och utvärdering av undervisning som främjar elevernas kraftfulla fo-tosynteskunskaper. För att illustrera den stödjande rollen av organiserande syften i didaktisk analys och undervisningsdesign, genomförde vi två hela lektioner och initierade en tredje. Data samlades in genom videoinspelning som underlag till att utvärdera designen, som sedan analyserades och transkriberades. Undervisningen genomfördes i en skolklass i årskurs fem, där totalt fjorton elever deltog. Undervisningen bestod av kemiska begrepp och förklaringsmodeller, de kemiska processerna i fotosyntesen, förbränning och cellandning och slutligen fotosyntesen kopplat till de kemiska reaktioner som sker i djur och växter.Resultatet exemplifierar hur modellen organiserande syften gav stöd till planering, genomförande och utvärdering av lektionsinnehållet. I analysen var be-greppsapparaten ett stöd till förbättringar av undervisningsdesignen. Modellen guidade undervisningen mot kontinuitet och progression och möjliggjorde reflektion och revidering av innehållet på ett tydligt sätt. En slutsats av studien är att exemplifiering visar hur organiserande syften kan fungera som stöd för att reflektera kring hur man anpassar och kombinerar lärarens övergripande syften med undervisningen och överbryggar till det mer elevnära närliggande syftet. Det är därför ett didaktiskt verktyg som kan stödja lärare att skapa foto-syntesundervisning som är relevant och intressant för eleverna och på flera sätt möjliggöra att deras naturvetenskapliga kunskap blir kraftfull.

Apoiando-se nos referenciais teórico-metodológicos do Interacionismo Sociodiscursivo (ISD) (BRONCKART, 2012), da Didática do grupo de Genebra (SCHNEUWLY; DOLZ, 2004), no que diz respeito à transposição e modelização didática de gêneros e em estudos de autores brasileiros que publicam nessa linha (GONÇALVES, 2011; BARROS, 2012), a presente pesquisa apresenta a análise e os resultados de aprendizagem decorrentes do desenvolvimento de uma Sequência Didática (SD) elaborada em torno do gênero notícia e utilizada para ampliar os domínios das capacidades da linguagem escrita, com uma turma do 5º ano do ensino fundamental, de uma escola municipal do interior do Estado de São Paulo. Com base na concepção de que os alunos utilizam três capacidades de linguagem (de ação, discursiva e linguístico-discursiva) no processo da produção textual (SCHNEUWLY; DOLZ, 2004), a SD foi elaborada a fim de contemplar essas capacidades e levar os alunos a sua mobilização e, com isso, dominar o gênero ensinado. Para a transposição didática do referido gênero, foi elaborado um modelo didático que, por sua vez, possibilitou a elaboração da SD desenvolvida no ano escolar citado. A metodologia utilizada resultou em um conjunto de 11 oficinas e 23 atividades didáticas de linguagem, que contemplaram as quatro etapas da SD. Na primeira etapa foram desenvolvidas 3 oficinas e 10 atividades; na segunda, foi realizada 1 oficina e 1 atividade; na terceira, foram desenvolvidas 3 oficinas e 8 atividades e, finalmente, na quarta etapa, foram realizadas 4 oficinas e 4 atividades. Os resultados são ancorados na análise das produções iniciais e finais do gênero notícia, a partir das capacidades de linguagem distinguidas pelos referenciais que embasam esta pesquisa: capacidade de ação, capacidade discursiva e capacidade linguístico-discursiva; com enfoque avaliativo-comparativo para verificar se houve ampliação das capacidades de linguagem. Como produto da pesquisa, um caderno didático denominado “Gênero Notícia: proposta de ensino de produção textual para os anos iniciais do Ensino Fundamental”, foi construído, e será disponibilizado aos professores dos anos iniciais do Ensino Fundamental como uma ferramenta pedagógica para contribuir no planejamento de suas ações didáticas realizadas no ensino, de modo sistematizado. / This research was undertaken with the gender focus textual news as a means articulator between social practices and language practices in the classroom. Relying on theoretical and methodological frameworks of Interacionism Sociodiscursivo (ISD) (BRONCKART, 2012), Didactic of the Geneva group (SCHNEUWLY;. DOLZ, 2004), with regard to the transposition and didactic modeling of genres and studies of Brazilian authors who publish this line (GONÇALVES, 2011; BARROS, 2012), this research presents the analysis and the learning outcomes of the development of a Didactic Sequence (SD) developed around the news genre and used to expand areas of skills of written language, with a class of 5th grade of elementary school, a public school in the state of São Paulo. Based on the concept that students use three language skills (action, discursive and linguistic-discursive) in the text written production process (SCHNEUWLY; DOLZ, 2004), the SD was developed in order to include these capabilities and take students their mobilization and thereby dominate the genre taught. For the didactic transposition of that genre, it designed a teaching model that, in turn, enabled the development of the SD developed in the school year cited. The methodology used resulted in a set of 11 workshops and 23 educational activities language, which contemplated the four stages of SD. In the first stage have been developed 3 workshops and 10 activities; the second was held one workshop and one activity; the third were developed workshops 3 and 8 activities and finally, the fourth stage, there were 4 workshops and 4 activities. The results are anchored in the analysis of initial production and final news genre, from the language capabilities distinguished by references that support this research: action capability, discursive capacity and linguistic-discursive capacity; Evaluative-comparative approach to see if there was an increase of language skills. As the research product, a didactic book called "Gender News: proposal for textual production for the early years of elementary school" was built, and will be available to teachers in the early years of elementary school as an educational tool to help in planning their didactic actions taken in education, systematic way.
