Following the widespread adoption of the Next Generation Science Standards (NGSS) by many states, school districts were required to redesign their science curriculum to increase students’ understanding of scientific concepts and processes.
“With NGSS, students are supposed to think more like scientists and engineers. It’s all about talking about the phenomenon,” said Ana Butler, project manager for the Quality Talk project, in the Department of Educational Psychology, Counseling, and Special Education. “While the standards say ‘this is what you need to do,’ they don’t educate teachers on how to do it. That’s where QT Science comes in.”
Like other Quality Talk projects, QT Science comprises four components — instructional frame, discourse elements, teacher modeling and scaffolding, and pedagogical principles. Each component helps students and teachers to use talk as a tool to contribute to critical thinking and high-level comprehension.
Quality Talk follows a unique student-led approach where teachers learn to slowly release leadership control of their classroom discussions and allow the students to lead their own discussions on theories and ideas relating to an observation (i.e., a phenomenon) they witnessed. To do this, teachers receive professional development training from QT Science coaches who help with the transition. Butler, who was a teacher for 23 years before coming to Penn State, said this can sometimes be very difficult.
“I speak for myself as a teacher, you have to be pretty confident with your own knowledge and abilities as well as your students' to release the responsibility of providing affirmation and guidance over to students,” she said.
In order for Quality Talk to be successful, students also must learn how to ask questions that promote critical thinking and invite thought-provoking responses. The teacher gives a series of lessons explaining the different types of questions and responses that are used for argumentation to prepare students for their independent discussion.
“As a former teacher, I know what it is like to ask a student ‘Why do you say that?’ and they say, ‘Because,’” Butler said. “So, we provide teachers and students with the tools necessary to help develop more critical thinking skills and we’ve seen tremendous changes from the beginning of our baseline to our QT post-tests.”
Butler also said it is important to understand that Quality Talk isn’t designed to be used for every lesson in every class. For example, she said, a four-day sequence of a 40-minute class could be broken down to include a 10-minute Quality Talk lesson to teach students some aspect of the different types of questions or responses of argumentation. The next day, the teacher could incorporate that lesson into their science lesson.
“We’ve designed a template for our science content lessons that incorporate QT and we have a QT Science catalyst worksheet that helps students get the conversation going by encouraging consideration of potential questions, claims and arguments,” Butler said, explaining that the lessons and worksheets are designed to follow the five E’s — engage, explore, explain, elaborate and evaluate.
