I teach biology with the belief that students understand living systems more deeply when they can
connect what they observe to a model, a mechanism, or a body of evidence. Biology contains an
enormous amount of information, but memorizing vocabulary is not the same as understanding how
systems work. My responsibility is to build the knowledge students need while giving them repeated
opportunities to investigate phenomena, interpret data, revise explanations, and communicate biological
reasoning.
Students often enter biology with ideas that are reasonable from everyday experience but incomplete
from a scientific perspective. I begin units by finding out what students already think about the
phenomenon we are studying. A question about why siblings differ, how a population changes, or how
cells obtain and use energy can reveal useful prior ideas as well as misconceptions. I return to those
initial explanations as students gather evidence so that learning becomes a visible process of refining a
model rather than simply replacing one answer with another.
I use investigations and models because biology is full of processes students cannot directly see.
Students may work with microscopy, simulations, ecological data, models of cellular processes,
inheritance patterns, or population changes. I teach students how to identify variables, construct tables
and graphs, look for patterns, and distinguish observations from interpretations. Laboratory work is
most valuable when students have to make sense of evidence and decide what it supports, rather than
simply follow directions and record a predetermined conclusion.
Explicit instruction remains important in my classroom. Students need accurate vocabulary, background
knowledge, quantitative tools, and carefully sequenced concepts to reason about biology. I use short
explanations, diagrams, annotated models, worked examples, and guided practice when a concept is
difficult or unfamiliar. I then return responsibility to students through source analysis, problem solving,
discussion, modeling, and investigation. I want students to know enough biology to ask better questions
and use evidence more intelligently.
I place particular emphasis on making connections among biological scales. Students should be able to
move from molecules and cells to organisms, populations, ecosystems, and patterns of evolution
without treating each topic as an isolated chapter. When studying heredity, for example, students can
connect variation to biological mechanisms and then examine how evidence about variation helps
explain patterns in populations. When studying ecosystems, they can connect energy and matter at the
organism level to interactions and changes across a larger system. These connections make the
subject more coherent and more useful.

Discussion and scientific argument help students make their reasoning visible. I use partner
explanations, small-group model building, evidence-sort activities, and whole-class discussions in which
students compare claims and ask what evidence supports them. I teach students to separate a claim
from its evidence and reasoning. When two explanations differ, I ask students to identify what each
explanation accounts for and what additional evidence might help decide between them. Changing an
explanation because the evidence changed is treated as a strength of scientific thinking.
Assessment should show what students understand and how they are thinking. I use quick concept
sketches, prediction checks, data interpretations, exit responses, model revisions, short constructed
explanations, and laboratory reflections to identify misunderstandings during instruction. Larger
assessments may ask students to explain a biological phenomenon, interpret data, evaluate a model, or
defend a claim using evidence. I use the results to decide what needs another representation, a
different example, more practice, or an extension rather than waiting until the end of a unit to discover
that students were confused.
I am intentional about inclusion because biology classes bring together students with different prior
experiences, reading levels, language backgrounds, and confidence in science. I provide visual
representations, vocabulary support, structured collaborative work, accessible versions of complex
texts, and multiple ways for students to communicate their reasoning. For multilingual learners, I make
scientific language explicit while keeping the intellectual task demanding. I also avoid assuming that a
student's success depends on being naturally 'good at science'; careful observation, persistence,
evidence use, and reasoning are skills students can develop.
I want students to see biology as a way of understanding both the living world and their place within it.
Topics such as health, biodiversity, genetics, ecosystems, evolution, and human impacts can raise
questions that require careful use of evidence and attention to uncertainty. I do not want students to
memorize isolated answers to those questions. I want them to become more capable of reading
scientific information, evaluating evidence, recognizing the limits of a conclusion, and explaining how
biological ideas apply to real situations.
Ultimately, I want students to leave biology with a durable way of thinking. They should be able to
observe a biological phenomenon, ask a useful question, build or use a model, analyze evidence,
revise an explanation, and communicate what the evidence supports. Whether a student continues into
a health profession, laboratory science, environmental work, another field, or a life outside STEM, those
habits remain valuable. I also treat my teaching as an ongoing process of inquiry: I study student work,
look for persistent misconceptions, reflect on which investigations produced meaningful reasoning, and
revise my instruction so that students have stronger opportunities to do authentic biology themselves.
