While the pupils from the control group received no specific…

There is little research on English language learners (ELLs) in relation to learning disability (LD) assessment and identification. More important, there is a scarcity of research on models and strategies that enhance learning opportunities and outcomes for ELLs prior to an LD diagnosis. We describe in this article an innovative language…

The authors used the Motivated Strategies for Learning Questionnaire to investigate the effectiveness of problem-based learning (PBL) and traditional instructional approaches on various facets of students' self-regulated learning, including motivation and learning strategies. Participants included 61 tenth-grade students from 2 intact classes…

The purpose of this study was to examine if and how participation in a journaling workshop influenced the content of student journals.

One of the factors affecting students' learning in science is their existing knowledge prior to instruction. The students' prior knowledge provides an indication of the alternative conceptions as well as the scientific conceptions possessed by the students. This study is concerned primarily with students' alternative conceptions and with…
