Every teacher of the theory of evolution has an opportunity \u2013 and an obligation \u2013 to point out some of the practical implications of Darwinian theory for human conduct. A thoughtful biologist cannot fail to find (in Shakespeare\u2019s words) \u201c\u2026 tongues in trees, books in the running brooks, sermons in stones\u2026.\u201d If he is interested in people as well as in things \u2013 and a teacher should be, even if a researcher is not \u2013 he will want to help students hear the sermons evolution.<\/p>\n
A simple but effective technique for self-assessing readiness to teach a particular topic is to explicitly reflect on the student questions, \u2018Why do I need to know this stuff?\u2019 and \u2018What\u2019s in it for me?\u2019 Faced with these questions, real or implied, instructional decisions should be made to better address and reflect the needs of target learners. If the teacher\u2019s response does not have sufficient perceived relevance to the target learner, students find it quite easy to dismiss the \u2018stuff\u2019 as unimportant \u2013 something to be memorised for a test and forgotten. Preparation to teach evolution often carries with it an implicit additional question: \u2018Why should I believe this stuff?\u2019 An inadequate response to this question can undermine a teacher\u2019s credibility and compromise one\u2019s rapport with students and parents alike. How then should one prepare?<\/p>\n
One can address the situation academically by promoting evolution as one of the most powerful working tools available to the practicing biologist. The introduction of subsequent topics such as genetics, ecology, and animal behaviour, for example, need to be tied directly to their roots in evolutionary theory. Too often teachers make the mistake of treating such topics as though they have no relationship to evolutionary biology. This approach is insufficient alone, nonetheless, because it does not directly acknowledge students\u2019 emotional reactions to a topic of study they may perceive as controversial or about which they have preconceived (often inaccurate) conceptions. Accounting for students\u2019 emotional responses in advance prevents potential defensive reactions that can hinder (or even damage) student and teacher relationships.<\/p>\n
Relationships between students and teachers are important in creating classroom atmospheres of trust and co-operation. Opening ourselves up to students requires us to be aware of our own emotions, to observe and interpret students\u2019 emotions, and to cope with students\u2019 feelings as they are expressed. All of these are demanding and important \u2013 if rarely acknowledged \u2013 aspects of teaching.<\/p>\n
If an instructional environment that is conducive to learning generally requires the development of good student-teacher relationships, then a classroom atmosphere of trust is an especially important consideration when we engage students in the teaching and learning of evolution. Emotional scaffolding, therefore, is crucial to the successful teaching and learning of evolution. Quinlan (2016) refers to four key relationships necessary to construct this scaffolding \u2013 students with teachers being merely one of the four key relationships comprising a comprehensive emotional scaffolding \u2013 the others being students with subject matter, students with other students, and students with their developing selves.<\/p>\n
Recognition and a nurturing of these four relationships to manage students\u2019 emotional responses to evolution instruction demand that instructors:<\/p>\n
The teacher-student relationship begins on the first day of class. I often refer to it as the second worst day of the semester. From that first day, I systematically engage students in activities that enhance individual curiosity and build student-subject relationships, require collective problem-solving, and initiate opportunities for students to begin a social construction of possible responses to problems and puzzles (i.e., initiate student-student interactions). Each subsequent class session (hopefully) fosters positive conversations, builds mutual trust, and creates a nascent sense of being a part of a mutually supportive cohort. I get to know which students work well together and alter student-student learning interactions accordingly. If I have successfully created this sense of community over time, then the last day of the semester is the worst for both me and for my students, because there comes the reckoning that our time together has drawn to a close \u2026 and to give it up is ultimately bittersweet.<\/p>\n
The most difficult relationship to accomplish is that of students with their developing selves. This relationship requires pre-existing, established trust between teachers and individual students. Nonetheless, with that trust in place, I recommend the use of journaling as a non-threatening assessment in relation to teaching evolutionary biology.<\/p>\n
In their journals, students are encouraged to respond to three focus questions:<\/p>\n
Students are required to provide appropriate evidence to use as justification for any claims made in their journal entries. Students also receive frequent reassurance, as they study topics such as evolution, the environment, genetically modified organisms, etc., that it is perfectly valid, in making their journal entries, to accept or reject any scientific claim as long as the decision was based on sound argument and evidence. Instructor feedback is often restricted to reminding students to use observations directly from the class activities, especially in cases where students reject a specific scientific claim. This use of journaling with non-judgmental feedback provides students with a safe outlet to reflect on their perceptions of what they were experiencing in class and how they are emotionally responding to it. As students learn more about what evolution is\/is not, the vast majority of students transition from little to no understanding of evolutionary theory to a recognition that scientific theories (such as evolution) play an important role in providing us with tools to answer scientific questions and solve scientific puzzles.<\/p>\n
This current essay completes a set of four connected narratives that comprise a distillation of my recommendations for enhancing the teaching of evolutionary biology. First, as one builds an initial teacher-student relationship, I recommend teaching (reinforcing) the nature of science immediately prior to introducing study of evolutionary theory (see Essay One).4<\/sup> Second, I suggest introducing evolution as an example of how scientists apply theory in explaining patterns in scientific evidence and answering scientific questions (see Essay Two).5<\/sup> Third, I recommend introducing the abstract notion of necessary uncertainty and iterative refinement (i.e., self-correction) as key properties of all scientific research (see Essay Three).6<\/sup> Finally, I urge adopting pedagogical practices that ensure the development of positive learning environments (current essay).<\/p>\nReferences<\/h4>\n
