As formigas popularmente denominadas de cortadeiras mantêm uma relação direta com determinada espécie de
fungo. Essas formigas-cortadeiras retiram partes clorofiladas das plantas e as levam ao formigueiro para servir
de alimento ao fungo. São consideradas cultivadoras, pois apresentam cuidados para garantir o crescimento do
fungo, como a eliminação de esporos contaminantes e a extirpação de micélios infectados. Esse “cuidado” é
demonstrado pelas formigas em função dos fungos servirem de alimentos para elas. A interação entre estes
organismos fungos-formigas advém também da produção de determinadas substâncias químicas pelos fungos
que informam às formigas quando devem parar de transportar para o formigueiro as folhas que não sejam
adequadas ao crescimento fúngico. LOPES, S.; ROSSO, S. Bio: volume 3. São Paulo: Saraiva, 2010. p. 263. (Adaptado).

O Cerrado brasileiro é um hotspot global de biodiversidade em função do número elevado de espécies
endêmicas (mais de 4,6 mil espécies que não ocorrem em outro lugar) e da alta taxa de degradação. Um estudo
recentemente publicado na revista internacional Nature Ecology & Evolution aponta que o bioma Cerrado perdeu
46% da vegetação nativa e somente 20% permanecem protegidos. Segundo os autores, se não houver um
controle do desmatamento, nos próximos 30 anos haverá perda de até 34% das espécies nativas do bioma. O
desmatamento nessa região é “causado pela combinação do agronegócio, obras de infraestrutura, pouca
proteção legal e iniciativas de conservação limitadas”.

Predictions for the future of 'smart' education
Posted by Charley Rogers - January 22, 2018
A wave of new technology has been introduced into schools up and down the country changing the way teachers deliver lessons and how students learn.
A research by Randstad Education found schools and colleges have adopted the latest tech to improve teaching and make lessons more interactive and engaging. Some of the innovations already in use include ‘gamifying’ lessons by incorporating game-like rules and tasks to increase motivation. For example, Shireland Academy in the West Midlands included Minecraft on its curriculum.
Education, the research found, will become more project-based and include more interactive content to keep up with students’ changing attitudes towards traditional media. Classrooms, it is predicted, will join the Internet of Things – a network of devices like smartwatches that connect and share data with other items and systems – and create ‘smart schools’ where the teachers, students and devices become more connected.
Pressure on teachers – 75% find their workload unmanageable – as well as rising student numbers means technology will play a larger role performing tasks to save time. Teachers are also reaping the rewards as lessons and assessments move out of the classroom and onto platforms that make it easier for them to chart progress and achieve a better work-life balance. Education experts have highlighted the importance of new techniques that help teachers do their jobs.
However, while tech will become more commonplace in the classroom, it is expected to compliment teachers and not replace them. It´s important to understand that teaching tools have come a long way since the days when teachers used to write on chalkboards and present using an overhead projector.
The research says that students today benefit from some of the most exciting technology available to schools, but it’s not just the pupils who benefit from these innovations through invigorating lessons and virtual learning. Teachers are also reaping the rewards as lessons and assessments move out of the classroom and onto platforms that make it easier for them to chart progress and achieve a better work-life balance.
Technology has arrived and the teachers and classrooms of tomorrow are here today.

This is how the way the world measures success in education is changing
Since 2000 when the Organization for Economic Co-operation and Development (OECD) launched a global academic benchmark for measuring student outcomes by testing 15-year-olds, many global education systems have been impacted by what sometimes looks and feels like a race to rank high.
When the OECD launched the Programme for International Student Assessment — PISA — the idea was to enable countries to make cross-national comparisons of student achievement using a common/standard metric to increase human capital. In other words, higher academic achievement should corelate with earnings in the future and a country’s standard of living. As PISA states, it publishes the results of the test a year after the students are tested to help governments shape their education policies.
As PISA has developed, through seven global testing rounds every three years, with the first in 2000 and the most recent in 2018, for some it has gained a reputation as the “Olympics of education” given the widespread attention that country rankings receive following the release of results.
Now, partly in the face of criticisms, PISA is looking at expanding how and what it tests. As this process unfolds, policy-makers must remember that the social consequences of a test are just as important as the test’s content. Putting a new face on PISA will undoubtedly present various opportunities and challenges.
To date, PISA has been restricted to what is generally called the “cognitive” side of learning, focusing on reading, mathematics and scientific literacy. In addition to test questions, students and school principals fill out questionnaires to provide contextual information on student and school environment characteristics that can be associated with more or less favourable performance.
Countries that excel in PISA tests, such as Finland, a country with less than six million people, have become regarded by policy-makers as a “global reference society” — an ideal to aspire to — due to their high performance in PISA rankings.
Asian countries or jurisdictions like Singapore, Hong Kong (China) and Japan tend to consistently achieve exceptional PISA performances and hence get a lot of attention from other countries wishing to emulate their success via borrowing policy. For example, England flew teachers out to China to study mathematics teaching.
In the next administration in 2021, PISA will tackle creative thinking, trying to find ways to assess, and have students assess, flexibility in thinking and habits of creativity such as being inquisitive and persistent. The PISA team is also developing a way of testing students’ digital learning, which should be ready in time for the 2024 assessment.
However, it should be remembered that education policies from high achieving nations don’t migrate across international boundaries without consideration given to national and cultural contexts. Rather, innovations and changes in education require teachers to have the time and opportunity to re-educate themselves in relation to more recent insights in what it means to get the best out of children.

The OECD will need to respond to previous critiques and provide greater transparency around newer test instruments and the choices made to arrive at rankings. The latter is no small challenge since the future focus of PISA is based on topics which seem more difficult to evaluate than math, science or reading skills.
