If, as a teacher, I provide effective and quality math/science instruction for my students I will then observe an increase in student achievement. 

If effective and quality math/science instruction is provided through/by: (1) teaching in ways that associate real-life practicality and invite personal connection, (2) delivering differentiated instruction to ensure educational equity, (3) embracing professional development and lifelong learning, (4) practicing critical objectivity while contemplating “newer/better ways of teaching” math/science that are not research-based and rely on qualitative conjecture for validation, (5) combining multiple approaches (i.e. explicit and discovery-based teaching) that are evidence-based and focussed on developmental perspectives to inform teaching, (6) role-modeling enthusiasm of the subject content and context, (7) creating a collaborative, safe, and secure classroom culture and community, and (8) utilizing various methods of lesson delivery (i.e., technology, guest speakers, field trips) as well as integrating inquiry-based learning to raise student engagement, interest, and excitement, then student achievement will improve through/by: (1) developing personal connection to the curricular content, (2) ensuring every student is offered opportunity for growth and achievement, (3) empowering students to challenge and question the accepted as well as practice agency, (4) developing authentic relationships and personal connections, (5) expanding reflective and introspective practices, and (6) engaging in collaborative contributions which subsequently raise interest and motivation as well as responsibility, and accountability for personal learning. 

Katz (2014) states that quality classroom instruction and practice positively influence student academic outcome.  If effective math/science instruction is provided by intentionally addressing and integrating all of the aforementioned instructional variables within the control the of teacher, then student participation, engagement, and motivation will be impacted whereby positively affecting achievement.
