Next GEN Physical Science and Everyday Thinking

Implementation Versions

Next Gen PET is available in a Studio-style class version for small lab and discussion classroom environments of 12-36 students; and a Lecture-style class version for lecture-style classrooms. In both versions, students draw on evidence, discuss ideas, develop, test and modify models, and engage in practices of scientific argumentation.

The Studio-style class (SC) version is best suited for lower enrollment courses that meet ~5 hours/week and take place in a lab or workroom where students can work in groups around tables and perform experiments. In the SC version, students spend the majority of their time with their group of 3-4 peers making predictions, performing experiments, drawing conclusions, answering questions in a workbook, and discussing their ideas both within their group and with the whole class.

Implementation Versions

The Lecture-style class (LC) version is best suited for courses that meet ~2.5 hours/week in lecture-style classrooms where students have desktops on which they can work. The LC version is suitable for courses with large enrollments, or in courses with smaller enrollments with limited meeting time and facilities. The content and pedagogical approach is similar to the SC version, but in the LC version: (1) students can do experiments requiring simple materials on their desktops, but for more extensive experiments, they watch videos; (2) students respond to questions (using hand-held response devices [e.g., “clickers”] or smart phones) to share ideas with the whole class; and (3) the instructor manages the class time through a set of PowerPoint™ slides that align with the student materials.

The table below summarizes the differences between structural features of the two versions. To see examples of both versions, click on one of the links below: Developing Model of Magnetism, Interactions and Forces. See also the Design Principles section of this website for a table summarizing the differences in how each version implements the design features of the curriculum.

The following table shows how the design principles are put into in the studio-style class and lecture-style class versions of Next Gen PET .

Design Principle Studio-style class (SC) Lecture-style class (LC)
1. Learning builds on prior knowledge. Questions within activities are designed to elicit and build on students’ initial ideas. Similar to SC.
2. Learning is a complex process. Big ideas/science practices (e.g. writing explanations) developed within & across units. A variety of question types guide students’ thinking. Extensions (homework) are computer-based tutorials that include online quizzes Similar to SC, except students do not write their own explanations; instead they evaluate carefully crafted explanations for accuracy. Extensions are the same as SC.
3. Learning is facilitated through interaction with tools. Students use hands-on materials, data acquisition tools and simulations, and answer questions on activity sheets. Students watch videos of experiments, demos and simulations, do simple hands-on activities (optional); answer questions with ‘clickers’ and on lesson sheets
4. Learning is facilitated through interactions with others Students engage in small group and whole class discussions. Students discuss thinking w/ neighbors, limited sharing with whole class.
5. Learning is facilitated through establishment of certain specific behavioral practices and expectations. Written prompts/instructor comments support expectations of providing evidence, active participation, and responsibility for learning. Similar to SC except the degree of participation is less and students are expected to reach consensus at end of each lesson.
