Developing students’ systems thinking is important but challenging in middle-school ecology. This quasi-experimental study examined whether an instructional package combining case-based learning and concept mapping, as implemented under routine classroom conditions, was associated with different patterns of growth across levels of the Systems Thinking Hierarchy. A total of 177 eighth-grade students from six intact classes completed parallel pre- and post-assessments during an ecosystems unit. Student-level repeated-measures analyses showed no clear differential pattern at the level of identifying components and processes. Larger observed gains appeared in understanding relationships, organization, and matter-energy cycles, and a smaller pattern in the same direction appeared in generalization, temporal reasoning, and hidden dimensions. However, because students were nested within only six classes, each condition was taught by a different teacher, and the experimental teacher received targeted preparation, the findings should be interpreted cautiously as associations linked to an instructional package rather than as teacher-independent causal effects. The results suggest that classroom enactments combining cases and concept mapping may help students move beyond isolated ecological facts toward more relational explanations, while higher-order systems thinking remains difficult and likely requires longer-term scaffolding in routine middle-school biology lessons over a short instructional unit.

Concept maps were created as one of six measures to identify exceptionally talented students during the Cultivating Diverse Talent in STEM (CDTIS) project, with the goal of identifying and nurturing talents in students from groups traditionally underrepresented in special programs. New methods were compared with conventional methods to select students for an internship in the laboratories of scientists. In this article, we describe development, field testing, and implementation of the concept map assessments in life and physical science. Assessments were field tested in partner schools with high percentages of American Indian (97% to 100%) and Hispanic (83%) low-income students. Students were selected by considering their performance on all six assessments and were placed in internships along with students selected using conventional methods. Concept maps were successful: (a) students from partner schools demonstrated high levels of domain-relevant skills; (b) scores approximated a normal distribution; (c) scores of students from culturally diverse, low-income groups were very similar to the scores of students selected using conventional methods even though many of conventionally identified students had high grade point averages and came from schools in high-income areas with many educational opportunities. Students completed original research and presented posters to the university community and their local communities. Concept maps can be used alone or in combination with other assessments; their use needs to be studied with larger groups of students and in other contexts.
