Studies show that spatial interventions lead to improvements in mathematics. However, outcomes vary based on whether physical manipulatives (embodied action) are used during training. This study compares the effects of embodied and non-embodied spatial interventions on spatial and mathematics outcomes. The study has a randomized, controlled, pre-post, follow-up, training design (N = 182; mean age 8 years; 49% female; 83.5% White). We show that both embodied and non-embodied spatial training approaches improve spatial skills compared to control. However, we conclude that embodied spatial training using physical manipulatives leads to larger, more consistent gains in mathematics and greater depth of spatial processing than non-embodied training. These findings highlight the potential of spatial activities, particularly those that use physical materials, for improving children's mathematics skills. 相似文献
The goal of this study was to investigate the timing of online homework completion and its effects on student performance. Data was collected from two large, first-semester general chemistry sections at a southwestern university. Specifically, this study aims to explore the link between when students complete their homework relative to the date the material was covered in lecture and student performance in that class. Topics covered in the study included VSEPR, Lewis structures, and molecular geometry. Performance was measured by different variables, namely in-class clicker scores (short-term) and exam grade (long-term). Students were divided into three groups: students who completed the relevant homework within 2 days after the lecture (before the next lecture), those who completed the homework 2 to 4 days after the lecture, and students who completed the homework more than 4 days after the material was covered in lecture. The study also took into consideration student reasoning abilities, as measured by the Test of Logical Thinking (TOLT), with a focus on at-risk students (low TOLT students). Results showed promising findings for low TOLT students. Instructors can employ results from this study to help their students better utilize the online homework resources.
A sample of 100 students from junior high school physical science, high school chemistry, and introductory college chemistry were examined for understanding of five chemistry concepts. The concepts addressed were chemical change, dissolution of a solid in water, conservation of atoms, periodicity, and phase change. The amount of experience with the concepts (grade level) and reasoning ability (developmental level) were examined as possible sources of variation in student understanding. Differences in understanding with respect to grade level were found to be significant for the concepts of chemical change, dissolution of a solid, conservation of atoms, and periodicity. However, few of the students in the college chemistry sample exhibited sound understanding of chemical change, periodicity, or phase change. The use of particulate terms (atoms, ions, molecules) increased across the grade levels. Reasoning ability proved to be a significant factor for student understanding of conservation of atoms and periodicity. An examination of the number and types of misconceptions across the grade levels revealed several interesting patterns and suggested sources for the students' alternative conceptions. 相似文献
The present study investigated the ability of 3- and 4-year-old children to perform tasks which require matching sets of sounds to numerically equivalent visual displays. We found that 3-year-olds performed at chance on the auditory-visual matching task, while 4-year-olds performed significantly above chance. There is evidence that mastery of the linguistic counting system is related to success on this task. These findings are unexpected given previous research reporting that 6–8-month-olds can detect the numerical equivalence between a set of sounds and items in a visual display. 相似文献
Two experiments tested the claim that the transparency of Korean fraction names promotes fraction concepts (Miura, Okamoto, Vlahovic-Stetic, Kim, & Han, 1999). In Experiment 1, U.S. and Korean first and second graders made similar errors on a fraction-identification task, by treating fractions as whole numbers. Contrary to previous findings, Korean children performed at chance when a whole-number representation was included. Nonetheless, Korean children outperformed their U.S. peers overall. In Experiment 2, U.S. children's performance improved when fraction names were used that explicitly referred to part-whole relations like Korean fraction names. U.S. children's scores actually exceeded those of Korean children. Thus, although the differences in fraction names may influence children's performance, this may not account for the reported cross-national differences. 相似文献
The study examined how institutional and student characteristics may influence the earning of student success points by state-supported community colleges under the Texas performance funding system that was fully implemented in the 2016–2017 biennium. Texas has historically funded community colleges based on an enrollment formula; however, the funding system was revised in 2013 by setting aside 10% of the enrollment-based formula funding appropriations to be earned back through a performance funding system based on student success points earned. The quantitative study used a correlation design with three hierarchical multiple regression analyses to examine the relationships between the student outcomes measures for public community colleges and institutional and student characteristics. The data examined were collected by the Texas Higher Education Coordinating Board and made available to the public through an interactive website tool. Findings showed that although several student and institutional characteristics were significant predictors of the total success points earned, when the analysis focused on the change in success points between two sets of three-year averages, none of the student or institutional characteristics were significant predictors. These findings support the design of the Texas performance funding system and suggest that community colleges serving higher proportions of at-risk students, including students who are a minority, low socioeconomic status, part-time, and are age 25 and older, will not be disadvantaged using the system’s methodology of comparing an institution to its own historic performance. The contributions of this study are intended to assist state policymakers who are designing performance funding systems. 相似文献
Preparing special educators who are knowledgeable about evidence-based interventions for teaching reading to students with
reading difficulties and who are capable of using curriculum-based assessments to monitor student progress and differentiate
interventions is vital to the success of current school reform efforts. The primary purpose of this exploratory study was
to examine the effect of tutoring and using assessment to monitor the progress of struggling readers on preservice teachers’
(PSTs’) knowledge and preparedness to teach reading. Also of interest was whether reading scores of tutored students improved.
PSTs (n = 18) in an undergraduate reading methods course tutored at-risk second graders using an evidence-based intervention and
monitored students’ progress weekly. PSTs made significant growth on a measure of teacher knowledge about the structure of
language and on a survey of their preparedness to teach reading. A qualitative analysis of PSTs’ weekly reflections and final
reports revealed that the majority used curriculum-based assessment data to describe students’ response to tutoring and were
beginning to use that data to make instructional decisions. On average, tutored students improved reading fluency, but did
not demonstrate significant growth in reading relative to national norms. Implications and limitations of the study are described
and directions for future research are discussed. 相似文献
