Pathways to Scientific Teaching, Chapter 5a of 7: Novel assessments: detecting success in student learning
This article illustrates how multiple methods can be used to assess student understanding of the “novel weapons hypothesis” presented in the Callaway and Ridenour review of theories regarding invasive plant species[attached]. The paper introduces students to concepts of natural selection, fitness, competition, and invasion of exotic species. The assessments we describe here engage students ...

An Assessment of Assemblage Nestedness in Habitat Fragments
This experiment illustrates how ecological theory can help conserve native species in a
fragmented landscape. It is germane to units on biogeography, human impacts on
ecosystems, landscape ecology, conservation, and restoration. During the first lab, the
instructor introduces the process of habitat fragmentation, the degree to which species
in species-poor assemblages are proper subsets of...

Assessment of the teaching of evolution by natural selection through a hands-on simulation
Given the expense, time and considerable teacher effort required to perform hands-on activities in the classroom, their consequences for student learning need to be evaluated. This study takes one example of student-active learning, students collecting and analyzing their own data, and asks whether the physical act of collecting data increases students’ learning of natural selection and affect...

Pathways to Scientific Teaching, Chapter 5c of 7: Unleashing problem solvers: from assessment to designing research
Can transgenes be kept on a leash?” ask Marvier and Van Acker in the [attached] review article. “No”, they answer, “the movement of transgenes beyond their intended destination is a virtual certainty”, and furthermore “it is unlikely that transgenes can be retracted once they have escaped”. Would these bold statements engage students, revealing the realities and complexities of gene...

Leaves as Thermometers
Plant morphology reflects evolutionary solutions to environmental constraints. In this experiment, students use this principle to predict the climate at their site. They collect and measure a set of traits on local tree leaf samples during the first meeting. At the following meeting(s), they pool their data and are introduced to a global database of climate and leaf morphology. In groups, they...
