To understand what the "full picture" is in education, you must first know what the partial picture is. In education, we already have the partial picture. A simple example of this would be how public schools teach history. I took the liberty of looking up some common history textbooks used in schools and textbooks I remember using in high school, and every single book I found was written by a white American man. How can we get the full picture if we only have one perspective?
There are so many different stories and perspectives on everything that happens in our world, and yet we hear the same, very few stories in our public education system. Our education system and textbooks focus heavily on the experience of white Americans. When we discuss other races, we give brief stories that only focus on the final moments of overcoming racism. We don't talk about their achievements. We don't talk about the years and years of oppression and abysmal things that happened to them. An example of this would be the story of Ruby Bridges. The only thing I learned about her was from seeing a picture of her walking into a white school. I only saw her one moment of overcoming a racist boundary. I never knew about the awful remarks, the ostracization, and the rocks that were thrown at her. History books only show a glorified version of America overcoming racism and the achievements of white historical heroes, but that is not real history. That is not the full picture.
To get the full picture, we need to find unspoken stories. We need to listen to marginalized groups. We need multiple perspectives. If you look up Ruby Bridges, you will still just see the picture of her walking to school. It is more challenging to find pictures of the awful things happening, but if you listen to her story... you will get the full picture.
