This systematic literature review was conducted to explore the effectiveness of problem-based and project-based learning (PBL) implemented with students in early elementary to grade 8 (ages 3–14) in mathematics and science classrooms. Nine studies met the following inclusion criteria: (a) focus on PBL, (b) experimental study, (c) kindergarten to grade 8 level, and (d) focus on mathematics or science content. For these studies, we examined: the definitions of PBL used, the components of PBL explicitly identified as salient to student learning, and the effectiveness of PBL. This review found that although there is no consistent definition of PBL, PBL is an effective method for improving K–8 students’ science academic achievement, including knowledge retention, conceptual development, and attitudes. Implications and limitations are discussed.

Teachers need to be able to design and implement problem-based learning (PBL) experiences to help students master the content and the processes in new mathematics and science education standards. Due to the changed population of learners within schools, it is also critically important that teachers in the elementary grades have the abilities to work effectively with English language learners (ELL). This article discusses the implementation of a major initiative by our teachers college to achieve both of these goals through Problem-Based Enhanced Language Learning (PBELL), which combines PBL, enhanced opportunities for language, and ELL methods. The implementation began with a small group of faculty members developing and piloting PBELL experiences, with coaching spread throughout the program. Our student-teachers are graduating with multiple opportunities to experience PBELL as learners and to design and implement PBELL experiences.

Teachers’ problem-based learning knowledge, abilities, and attitudes are important factors in successful K–12 PBL implementations. This article describes the development and use of a free, online module entitled Design a Problem-Based Learning Experience. The module production, aligned with theories of andragogy, was a partnership between the recipients of a grant using PBL to enhance English language learner education and the Sanford Inspire Program. A multistage evaluation design was used in the iterative process of module creation. Starting with an initial white paper, the module’s conceptualization, development, pilot testing, and refinement are described, along with the current use statistics. The URL for the new, easier to access location for the module is provided, along with suggestions for its use in teacher education.

In Problem-Based Learning (PBL), a problem is posed before students have learned how to solve it. Language and PBL pair well for effective learning environments. Informed by language-based theories of learning and strategically adding methods for working with English Language Learners (ELLs), we developed an approach called Problem-Based Enhanced-Language Learning. In this article, we provide the background for the approach and explain the specifics of implementing Bears in a Boat, which we have used in many contexts including a second-grade urban classroom and a third-grade US-Mexico border classroom with significant numbers of ELLs. The science content learner outcomes are that students will be able to: (a) describe what it means to sink and float and (b) explain that the more weight you add to a boat, the deeper it will float.
