Educators seek to develop students' mathematical knowledge retention to increase student efficacy in follow-on classwork, improvement of test scores, attainment of standards, and preparation for careers. Interactive visuals, feedback during problem solving, and incorporation of higher-order thinking skills are known to increase retention, but a…

Testing to build research-based evidence to support teaching methodologies that promote student learning has become increasingly important in a standards-based educational system in the United States. One challenge is the lack of studies that support specific methodologies so teachers and administers can make professional development and…

Providing exploratory activities prior to explicit instruction can facilitate learning. However, the level of guidance provided during the exploration has largely gone unstudied. In this study, we examined the effects of 1 form of guidance, feedback, during exploratory mathematics problem solving for children with varying levels of prior domain…

The purposes of the present study were (a) to compare US and Korean 8th graders' mastery of knowledge and skills in the mathematics test of the Trends in International Mathematics and Science Study (TIMSS) 2003 using a cognitive diagnostic testing method and (b) to find links between teachers' instruction and students' mastery of mathematics…

Studied the effects of implicit instruction, explicit instruction, and values clarification instruction. All treatment groups reported significantly higher knowledge scores than did the control group, but only the explicit instruction treatment was able to produce any changes in attitudes or behavior.

Compares the academic achievement of students from two Dutch medical schools, one employing problem-based learning (PBL) and one using non-PBL methods. No systematic differences were found on total test scores. Differences were demonstrated only at the level of individual questions. Results indicate that PBL and non-PBL instructional methods have…
