Personal Learning Enviroment – Mariana Tracastro
Hello,
Bellow is my primary personal learning environment, categorized into five tool groups: search, learn, organize and store tools, share, and create tools.

In my effort to enhance my existing Personal Learning Environment (PLE), I identified several valuable tools that I incorporated into the improved version as you can see below. Specifically, I introduced new tools under the “learn” category, such as Coursera, CNN, Spotify for podcast listening, Grammarly, and others. Additionally, in the “organization and storage” category, I came across news apps like Pocket, enabling me to save useful links. Under the “create” category, I included Lightroom app to edit photos and more. As for sharing, I haven’t used Twitter before, but I plan to download it to explore its potential.

Mariana Tracastro – Personal presentation
Hello, I’m Mariana!
I’m originally from Brazil, but I’m currently living in Madrid because I’m pursuing a master’s degree called AMIR (Advanced Materials: Innovative Recycling). This program has provided me with a deep understanding of the circular economy. As a result, I’ve shifted my mindset, and now, when evaluating any product or service, I take a critical look at its circularity. I consider factors such as how difficult it is to dismantle a product and how a service can minimize waste, among other things.
When I was younger, I had to move to 11 different cities because of my father’s job. So, I learned to adapt to new schools, make new friends, and discover new environments. This experience has made me quite dynamic and a communicative person.
I would say I am a person who really loves a challenge.
I always want to understand things and solve problems. I believe this is one of my driving forces. I really enjoy the challenge of analyzing the symptoms, identifying what is wrong, and finding the solutions. That is the reason I chose to work in the engineering field.
I hold a degree in Materials Engineering with 8 years of professional experience in the mining and automotive industries. My exposure to different cultures through my diverse peer network enables me to think in a cross-cultural, cross-functional way and enhances my abilities to tackle a wide range of customer issues and propose innovative solutions.
