This study assessed the effectiveness of a spatialized mathematics intervention on the mathematical performance and spatial visualization skills of students from an underprivileged Indonesian community. Grade 8 students (N = 407) were assigned to one of twelve experimental classes, receiving the spatial mathematics intervention, or one of seven…

To achieve adaptive learning, a dynamic assessment system equipped with a cognitive diagnosis was developed for this study, which adopts a three-stage model of diagnosis-intervention-assessment. To examine how this system influenced spatial geometry learning, the study used a quasi-experimental method to investigate student learning outcomes…

Knowledge about one's own cognitive processes is the basis for the monitoring and regulation of learning processes for effective reading comprehension. Taking verbal cognitive ability into account, the present study aimed to examine the developmental trajectories of reading comprehension and declarative metacognitive knowledge and their…

Students' spatial ability plays an important role in instruction with dynamic and static visualizations. This research was aimed at describing 1) the difference in learning achievement between the students who learned from dynamic visualization and static visualization, 2) the difference in learning achievement among students who have high spatial…

Mathematical representation is an important skill in mathematics learning that enables students to interpret and solve problems with ease. However, building confidence in such a skill can be difficult for some students, especially for those who lack self-motivation skills. Therefore, this study examines the effects of the think-talk-write strategy…

Mathematical problem solving typically involves manipulating visual symbols (e.g., equations), and prior research suggests that those symbols serve as diagrammatic representations (e.g., Landy & Goldstone, 2010). The present work examines the ways that instructional design of student engagement with these diagrammatic representations may…

Two ways of measuring change are presented and compared: A conventional "change score", defined as the difference between scores before and after an interim period, and a process-oriented approach focusing on detailed analysis of conceptually defined response patterns. The validity of the two approaches was investigated. Vocabulary…

The purpose of this study is to reveal the extent to which the sources of 6th- 8th grade students' self-efficacy beliefs predict their self-efficacy beliefs for learning and performance. The study is correlational and was conducted on a total of 1049 students during the fall term of the educational year 2010-2011. The data of the study were…

This study investigated the effectiveness of "Solve It!" instruction on students' knowledge of math problem-solving strategies. "Solve It!" is a cognitive strategy intervention designed to improve the math problem solving of middle school students with learning disabilities (LD). Participants included seventh- and eighth-grade…

Due to the scarcity of cross-cultural comparative studies in exploring students' self-efficacy in science learning, this study attempted to develop a multi-dimensional science learning self-efficacy (SLSE) instrument to measure 316 Singaporean and 303 Taiwanese eighth graders' SLSE and further to examine the differences between the two student…

This study examines the process by which system thinking perceptions develop within the context of a water cycle curriculum. Four junior high school students undergoing an especially designed inquiry-based intervention were closely observed before, during, immediately after, and 6 years after completing a year long systems-based learning program.…

Despite the developing infusion of three-dimensional, technological imagery, little has been done to explain the effects of two-dimensional versus three-dimensional imagery on the learning process. This study examined the effects of two-dimensional stimuli and three-dimensional stereoptic stimuli on spatial representation in drawings. A scene was…

Not all children cope equally well with the stresses and traumas life throws their way, and every educator recognizes that "deer in the headlights" look some children get when current events and past traumas combine to trigger a fight-or-flight stress response. No matter how safe the classroom may be in reality, trauma deactivates cognitive…
