This bibliometric analysis investigates the impact of Project-Based Assessments (PBAs) on conceptual understanding in STEM education from 2019 to 2024. By examining a dataset of 996 publications, the study highlights significant fluctuations in research outputs and the evolving focus on educational methodologies, particularly noting an…

We present adaptable activities for models of drug movement in the human body -- pharmacokinetics -- that motivate the learning of ordinary differential equations with an interdisciplinary topic. Specifically, we model aspirin, caffeine, and digoxin. We discuss the pedagogy of guiding students to understand, develop, and analyze models,…

Take a selection of balls and marbles along to a nearby playground slide and let students investigate factors that may influence how balls accelerate down an inclined plane. Students can make hypotheses in small groups, plan investigations to test multiple possible explanations and draw conclusions about the importance of different variables. The…

One way to help students understand the scientific inquiry process, and how it applies in investigative research, is to involve them in scientific investigation. An example of this would be letting them come to their own understanding of how different variables (e.g., starting products) can affect outcomes (e.g., variable quality end products)…

Viruses are all around--and within. They replicate inside the cells of living organisms. An estimated 1.6 million to 40 million of them occupy each cubic meter of the air people breathe. The activity described in this article helps students understand how the structure of a virus allows it to infect a specific set of organisms and cell types.…

Designed for a broad audience, including educators, camp directors, afterschool coordinators, and preservice teachers, this investigation aims to help individuals experience mathematics in unconventional and exciting ways by engaging them in the physical activity of building geometric shapes using ropes. Through this engagement, the author…

This article describes an exciting exploration-based activity in which students develop an alternative definition of factor that can help them solve problems like the one presented above. Students work in groups to collect data, analyze the data to make conjectures, and then spend a significant amount of time debating and justifying their…

The concept attainment lesson, recommended by Joyce, Weil, and Calhoun (2004), is designed to give students practice in analyzing data and developing critical-thinking skills--without a complicated lab setup. The inductive lesson structure leads students step by step to an in-depth understanding of a new idea and scaffolds their thinking as they…

Science classes are full of abstract or challenging concepts that are easier to understand if an analogy is used to illustrate the points. Effective analogies motivate students, clarify students' thinking, help students overcome misconceptions, and give students ways to visualize abstract concepts. When they are used appropriately, analogies can…

All teachers bring the goals and objectives of their math programs to life as they plan and present activities, establish procedures and expectations, and interact with children. Teachers' beliefs about what children need to know, their knowledge of how children learn, and the classroom environment they create all impact how children experience…

A classroom exercise to help college students of economics conceptualize, create, and learn from graphs is described. The technique is illustrated with an exercise concerning the concept of supply and demand in consumer markets. Classroom time required for the activity is small, and students become adept at manipulating models without anxiety.…

The evidence on learning communities suggests that student intellectual and psychosocial development is improved by participation. Faculty members become rejuvenated as learners once again through rediscovering the boundaries and intersection of their discipline with others. Active learning, collaborative learning, strategies to improve critical…

Explores the use of concept mapping as a college teaching technique, drawing on research on conceptual knowledge, concept formation, and classroom applications and variations. Specific activities for concept mapping and modeling are offered, and the nature of the teacher's and student's role is discussed. (MSE)
