Celebrate Hispanic & Latinx Heritage Month

This project is a part of the Hispanic & Latinx Heritage Month celebration because it supports a Latino teacher or a school where the majority of students are Latino.

My Students

A rigorous approach to a Chemistry class requires not only a great deal of visuals, conceptual discussion and theoretical models analysis, but it is also essential a deep understanding of the mathematical relationships between the concepts developed.

The program my students are enrolled to is a Magnet Program in a Title I school, with a 90% of minorities in the program, 90% of disadvantage social-economic families, but with a very successful performance.

Students in our program come from difference areas in the city, some of them very far from the school. Our program is very rigorous, taking our students in many cases AP level classes (college level classes taught in high school) as the first and only class on the subject. In these classes, for example, my AP Chemistry class, the students enter with the knowledge they got in their middle school and reach a college level in a single year.

My Project

Chemistry is about substances and chemical reactions. What the students commonly remember after some years of taking their Chemistry class are the vivid colors of some substances, those impressive deals of heat, light and sizzling of some reactions, and their teacher showing, manipulating and drawing molecular representations. These are great images stamped in their brain forever from their Chemistry class. But what level of understanding do they have about what they saw, observed, experienced? What's behind the retina impression? Working out the Chemical theoretical models help the students to learn meaningful knowledge. Chemical models need in most cases mathematical developments. Students need to go through the process of working numbers out. It is not enough to show them the calculations in the whiteboard. Unless they go through them personally, it won't be significative learning.

In a Chemistry class, having available calculators for all students is essential to develop one part of the syllabus.

The students work individually, in small groups (performing calculations and receiving feedback from their peers) and in a whole class group (modeling the calculations initially and solving general questions about notation, shortcuts, formalities...) to complete all aspects of this important task in any scientific discipline.
