Strong information literacy, collaboration, and argumentation skill are essential to success in problem-based learning (PBL). Computer-based scaffolding can help students enhance these skills during PBL. In this study, we investigated predictors of the quality of arguments high school environmental science students wrote in support of their…

Success in problem-based learning requires both strong information literacy to search for, evaluate, and use information effectively, and argumentation skills to generate coherent arguments. This study investigated the positive and negative effects of computer-based scaffolding to support high-school credit recovery students' information literacy…

The authors investigated the influence of engaging in a problem-based learning unit on middle school students' epistemic beliefs, and how such students' epistemic beliefs and approaches to argumentation within and outside of their small groups related. Data sources include state science achievement test scores, epistemic beliefs pre- and…

Strong information literacy, collaboration, and argumentation skills are essential to success in problem-based learning (PBL), and computer-based scaffolding plays a key role in helping students enhance these skills. As students search for information, identify root causes, and propose problem solutions, they are faced with choosing among…

Argumentation is central to instruction centered on socio-scientific issues (Sadler & Donnelly in "International Journal of Science Education," 28(12), 1463-1488, 2006. doi: 10.1080/09500690600708717). Teachers can play a big role in helping students engage in argumentation and solve authentic scientific problems. To do so, they need…

Students engaged in problem-based learning (PBL) units solve ill-structured problems in small groups, and then present arguments in support of their solution. However, middle school students often struggle developing evidence-based arguments (Krajcik et al., "J Learn Sci" 7:313-350, 1998). Using a mixed method design, the researchers examined the…

A critical step in problem-based learning (PBL) units occurs when groups present their solution to the central problem. This is challenging for middle school students because it involves the creation of an evidence-based argument (Krajcik et al., "Journal of the Learning Sciences" 7:313-350, 1998). Using a mixed method design, this study…

Problem-based learning (PBL) is an instructional approach in which students in small groups engage in an authentic, ill-structured problem, and must (1) define, generate and pursue learning issues to understand the problem, (2) develop a possible solution, (3) provide evidence to support their solution, and (4) present their solution and the…
