Basic Tree Thinking Assessment 1 (BTTA 1)

Purpose

The Basic Tree Thinking Assessment 1 (BTTA 1) is designed to evaluate your tree-thinking skills in majors undergraduate biology curriculum concentrated on evolutionary biology. Specific topics include the theory of evolution by Charles Darwin.

Population

The BTTA 1 is commonly administered in introductory biological evolution college courses.

Typical Performance

The BTTA 1 is a relatively new instrument and does not have an established performance range. As the LASSO platform collects more data, we will be able to offer better guidance on student performance.

Example question:

Validity

The BTTA 1 was originally developed in 2005. The development is detailed in
