Performance Assessment (Formative Assessment—on going)
1. Exit Tickets
2. Informal Observation (structured pair-work): teacher monitors and makes note addressing common
misunderstandings and gaps in understanding. Through cues or prompts redirect gaps or misunderstandings
3. Make an Appointment: group members share with each other and that group will then go to a different to
compare responses.
4. Thumbs Up and Thumbs Down: Pair opposite or split group based on arguments which would discuss concepts
further
5. Develop Series of Questions: students share thinking with teacher or members of group, students learn if he or
she has full, partial, or no understanding of the concept
6. Teacher Directed Questions: teacher developed questions to if students have full, partial, or no understanding of
the concept
7. Students analyze responses to open-ended question(s) made from other student responses—results in reflect on
own learning
8. Group projects enabling a number of students to work together on a complex problem that requires planning,
research, internal discussion, and group presentation.
9. Essays/Short Answers assessing students' understanding of a subject through a written description, analysis,
explanation, or summary.
10. Experiments testing how well students understand scientific concepts and can carry out scientific processes.
11. Demonstrations giving students opportunities to show their mastery of subject-area content and procedures.
12. Portfolios/Binders allowing students to provide a broad portrait of their performance through files that contain
collections of students' work, assembled over time
#1-6 Most commonly used on a day to day basis

Allele A variation of a gene’s nucleotide sequence (an alternative form or version of a gene).
Asexual reproduction The production of an offspring from one parent.
Cell The basic unit of structure and function for all living organisms. Cells have three common components: genetic material, cytoplasm,
and a cell membrane. Eukaryotic cells also contain specialized organelles.
Cell Cycle The series of events that take place in a cell leading to its division and duplication. The main phases of the cell cycle are
interphase, nuclear division, and cytokinesis.
Chromosomal Mutation A change in the structure of a chromosome (e.g., deletion, the loss of a segment of a chromosome and thus

the loss of segment containing genes; duplication, when a segment of a chromosome is duplicated and thus displayed more than once
on the chromosome; inversion, when a segment of a chromosome breaks off and reattaches in reverse order; and translocation, when a
segment of one chromosome breaks off and attaches to a nonhomologous chromosome).
Chromatids Each half of the chromosome; one of the two strands of the chromosome that becomes visible during mitosis and meiosis.
Chromosomes A single piece of coiled DNA and associated proteins found in linear forms in the nucleus of eukaryotic cells and circular
forms in the cytoplasm of prokaryotic cells; contains genes that encode traits. Each species has a characteristic number of
chromosomes.
Crossing‐over An exchange of genetic material between homologous chromosomes during prophase I of meiosis; contributes to the
genetic variability in gametes and ultimately in offspring.
Cytokinesis The final phase of a cell cycle resulting in the division of the cytoplasm.
Diploid A cell that contains two sets of chromosomes.
Frame‐shift Mutation The addition (insertion mutation) or removal (deletion mutation) of one or more nucleotides that is not indivisible
by three, therefore resulting in a completely different amino acid sequence than would be normal. The earlier in the sequence nucleotides
are added or removed, the more altered the protein will be.
Gamete A specialized cell (egg or sperm) used in sexual reproduction containing half the normal number of chromosomes of a somatic
cell.
Haploid describes a cell, nucleus, or organism that has only one set of unpaired chromosomes.
Interphase The longest‐lasting phase of the cell cycle in which a cell performs the majority of its functions, such as preparing for nuclear
division and cytokinesis.
Meiosis A two‐phase nuclear division that results in the eventual production of gametes with half the normal number of chromosomes.
Mitosis A nuclear division resulting in the production of two somatic cells having the same genetic complement as the original cell.
Mutation A permanent transmissible change of genetic material (e.g., chromosomal mutations and gene mutations).
Point Mutation A single‐base substitution causing the replacement of a single‐base nucleotide with another nucleotide (e.g., silent
mutation, in which there is no change in an amino acid; missense mutation, in which there is a different amino acid; and nonsense
mutation, in which there is an insertion of a stop codon in the amino acid which stops protein synthesis).
Semiconservative replication means that each "new" double strand consists of one original strand and one newly assembled strand.
Sexual reproduction The production of offspring through meiosis and the union of a sperm and egg.
