2. The teacher uses questioning and
discussion techniques that engage all learners. To meet the needs of all students, a teacher
should use instructional practices reaffirmed by research, pose effective
questions and provide sufficient wait-times for student response and give
assignments and organize activities that cognitively engage learners spanning
the range in ability. Moreover, teachers exemplifying research-based and growth-centered
teaching practice engage in habitual evaluation and modification of their
lessons and their effectiveness to ensure that they meet the needs of all
students [1].

In the video segments that show the teacher explaining to students
how to complete and interpret a 2x2 Punnett square using parental alleles and calculating
genotypic and phenotypic ratios and percentages using those completed Punnett squares,
the teacher demonstrates exemplary command of posing questions that elicit
higher-order thinking and providing adequate time for students to process
questions, analyze information, and provide an answer in response [2]. Throughout the lesson shown in the
two video segments, the teacher paces her questioning and explanation to meet
the needs of learners spanning the range in ability and patiently waits for
students to wrestle with the problem at hand, come up with an answer or
solution and correct themselves if necessary [2]. The teacher supports a positive learning environment by
affirming correct student responses and redirecting incorrect answers with
questions rather than outright stating that a given answer is wrong, assuring
students so that they willingly volunteer further insight and perspectives without
the fear of being wrong [2]. Along
the same lines, teacher accepted all student responses with respect and
support, comfortably engaging students in a learning atmosphere of mutual
respect wherein students of varying backgrounds feel comfortable with being randomly
called upon (00:28-00:40) to volunteer answers—an exchange representative of the
high expectations the teacher has for their students [5]. For example, the second video segment shows the teacher suggesting
to students to look at their notes (00:00-00:30) since the definition of genotype and phenotype are “part of their vocabulary,” challenging students to
engage and be prepared for questioning and giving all students—even those that
struggle more with the learning material—an equal opportunity to participate in
the learning process [3]. In the
second video segment, the teacher’s classroom management demonstrates the
reciprocal state of trust and respect the teacher and students have for each
other: the teacher trusts in the students’ capability to think for themselves
and regulate their own response after being notified that someone is indeed trying
to speak and the students respect for classroom in that they immediately stop talking
when asked (00:00-00:23) to let a fellow student properly volunteer her answer [4].
According to Pressley & McCormick in Child and Adolescent Development for Educators, expert on cognitive
development Jean Piaget stresses that students must be “active participants” in
their own learning, discovering knowledge in learning environments “conducive to student
exploration” (2007, pp. 68-69). The teacher shows regard for such a learning
environment in the first video segment when they prompt the students
(03:20-03:29) to analyze the genotype designation for homozygosity in dominance
and interpret the meaning of “homozygous” to predict the genotype labeling for the
homozygous recessive state, and, when a student correctly provides an answer, they
ask a probe (03:45-03:55) that prompts the students to evaluate the genotype
terms for heterozygosity of alleles based on the concept of homozygosity [4]. Another instance in which teacher
uses higher cognitive level of questioning to guide students toward expanding
upon and justifying their thinking can be found in the second video segment, in
which the teacher prompts (04:10-04:24) the students to think about allelic
dominance in analyzing a completed Punnett square to realize that dominant
alleles have phenotypic dominance [5].
During the lesson, there are some instances—missed opportunities—in which the
teacher chooses to “tell” rather than let the students discover the answer
themselves: when the teacher walks through the calculation of common ratios from completed 2x2 Punnett squares to the percentages of quarters to dollars
(06:00-06:29) in the second video, she poses questions and immediately answers
her own questions rather than wait for the students to arrive at each answer
themselves. Although the students show that they follow the authentic parallel
she conveyed when they answer her question (06:27-06:30) about how many
quarters there are in a dollar, teacher could have, instead, slowed down and
allowed students the chance to calculate and fully understand the meaning of
ratio/percentage solved for a 2x2 Punnett square when applying their
understanding of the comparison to money [6].
In this way, students are given the chance to practice solving the problem at
their own pace, and engage in the higher-order thinking processes of analysis [5].
The two instances in the shown in the lesson on 2x2 Punnett squares in
genetics demonstrates that the teacher exemplifies command of stimulating
student engagement and motivation to think about the content at the higher
cognitive thinking levels of analysis and evaluation and providing an adequate
amount of time to allow for student to discover knowledge at their own pace and
fully own their learning [5].
