Submicrorepresentations (SMRs) are a powerful tool for identifying misconceptions of chemical concepts and for generating proper mental models of chemical phenomena in students’ long‐term memory during chemical education. The main purpose of the study was to determine which independent variables (gender, formal reasoning abilities, visualization abilities, and intrinsic motivation for learning chemistry) have the maximum influence on students’ reading and drawing SMRs. A total of 386 secondary school students (aged 16.3 years) participated in the study. The instruments used in the study were: test of Chemical Knowledge, Test of Logical Thinking, two tests of visualization abilities Patterns and Rotations, and questionnaire on Intrinsic Motivation for Learning Science. The results show moderate, but statistically significant correlations between students’ intrinsic motivation, formal reasoning abilities and chemical knowledge at submicroscopic level based on reading and drawing SMRs. Visualization abilities are not statistically significantly correlated with students’ success on items that comprise reading or drawing SMRs. It can be also concluded that there is a statistically significant difference between male and female students in solving problems that include reading or drawing SMRs. Based on these statistical results and content analysis of the sample problems, several educational strategies can be implemented for students to develop adequate mental models of chemical concepts on all three levels of representations. 相似文献

In this study, a multiple-choice test entitled the Science Process Assessment was developed to measure the science process skills of students in grade four. Based on the Recommended Science Competency Continuum for Grades K to 6 for Pennsylvania Schools, this instrument measured the skills of (1) observing, (2) classifying, (3) inferring, (4) predicting, (5) measuring, (6) communicating, (7) using space/time relations, (8) defining operationally, (9) formulating hypotheses, (10) experimenting, (11) recognizing variables, (12) interpreting data, and (13) formulating models. To prepare the instrument, classroom teachers and science educators were invited to participate in two science education workshops designed to develop an item bank of test questions applicable to measuring process skill learning. Participants formed “writing teams” and generated 65 test items representing the 13 process skills. After a comprehensive group critique of each item, 61 items were identified for inclusion into the Science Process Assessment item bank. To establish content validity, the item bank was submitted to a select panel of science educators for the purpose of judging item acceptability. This analysis yielded 55 acceptable test items and produced the Science Process Assessment, Pilot 1. Pilot 1 was administered to 184 fourth-grade students. Students were given a copy of the test booklet; teachers read each test aloud to the students. Upon completion of this first administration, data from the item analysis yielded a reliability coefficient of 0.73. Subsequently, 40 test items were identified for the Science Process Assessment, Pilot 2. Using the test-retest method, the Science Process Assessment, Pilot 2 (Test 1 and Test 2) was administered to 113 fourth-grade students. Reliability coefficients of 0.80 and 0.82, respectively, were ascertained. The correlation between Test 1 and Test 2 was 0.77. The results of this study indicate that (1) the Science Process Assessment, Pilot 2, is a valid and reliable instrument applicable to measuring the science process skills of students in grade four, (2) using educational workshops as a means of developing item banks of test questions is viable and productive in the test development process, and (3) involving classroom teachers and science educators in the test development process is educationally efficient and effective. 相似文献

This study examined the differential effectiveness of traditional and discovery methods of instruction for the teaching of science concepts, understandings about science, and scientific attitudes, to learners at the concrete and formal level of cognitive development. The dependent variables were achievement, understanding science, and scientific attitude; assessed through the use of the ACS Achievement Test (high school chemistry, Form 1979), the Test on Understanding Science (Form W), and the Test on Scientific Attitude, respectively. Mode of instruction and cognitive development were the independent variables. Subjects were 120 Form IV (11th grade) males enrolled in chemistry classes in Lusaka, Zambia. Sixty of these were concrete reasoners (mean age = 18.23) randomly selected from one of the two schools. The remaining 60 subjects were formal reasoners (mean age 18.06) randomly selected from a second boys' school. Each of these two groups was randomly split into two subgroups with 30 subjects. Traditional and discovery approaches were randomly assigned to the two subgroups of concrete reasoners and to the two subgroups of formal reasoners. Prior to instruction, the subjects were pretested using the ACS Achievement Test, the Test on Understanding Science, and the Test on Scientific Attitude. Subjects received instruction covering eight chemistry topics during approximately 10 weeks. Posttests followed using the same standard tests. Two-way analysis of covariance, with pretest scores serving as covariates was used and 0.05 level of significant was accepted. Tukey WSD technique was used as a follow-up test where applicable. It was found that (1) for the formal reasoners, the discovery group earned significantly higher understanding science scores than the traditional group. For the concrete reasoners mode of instruction did not make a difference; (2) overall, formal reasoners earned significantly higher achievement scores than concrete reasoners; (3) in general, subjects taught by the discovery approach earned significantly higher scientific attitude scores than those taught by the traditional approach. The traditional group outperformed the discovery group in achievement scores. It was concluded that the traditional approach might be an efficient instructional mode for the teaching of scientific facts and principles to high school students, while the discovery approach seemed to be more suitable for teaching scientific attitudes and for promoting understanding about science and scientists among formal operational learners. 相似文献

The paper reports on aspects of an ESRC project, ‘The impact of Performance Threshold Assessment on teachers' work’ (ESRC R000239286). The paper begins by explaining the nature and technology of Threshold Assessment, and its location nationally within the performance management system recently introduced into schools in England. We review the monitoring procedures adopted for Round 1 of Threshold and draw attention to the limitations of such statistical data as are available. We locate Threshold within recent international developments characterised by managerialism and the culture of performativity that have increasingly come to dominate both the nature of policy‐making and definitions of ‘professionalism’. Drawing on interview material gained from thirteen case studies carried out in primary and secondary schools and in Local Education Authorities, we analyse the ways in which Threshold Assessment carries different significance for women and men teachers, heads and threshold assessors. We conclude that the new policies represent a further step towards the masculinization of education. 相似文献

Geospatially enabled learning technologies may enhance Earth science learning by placing emphasis on geographic space, visualization, scale, representation, and geospatial thinking and reasoning (GTR) skills. This study examined if and how a series of Web geographic information system investigations that the researchers developed improved urban middle-school learners’ GTR skills and their understanding of tectonics concepts. Paired-sample t tests for analyses of tectonics content knowledge and GTR achievement measures revealed statistically significant gains from pretest to posttest (p <.001) with large effect sizes. The findings provide support that GTR related to tectonics can be learned with appropriately designed learning activities using Web-based geographic information systems. 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.

The study investigated the structure and development of formal thought among tenth-, eleventh-, and twelfth-grade students. The subjects of the study were the total numbers of students attending the science, the economic, and the other sections of two higher secondary schools. Students' performance on a standardized Test of Logical Thinking (TOLT) was used as a measure of their cognitive abilities related to control of variables, proportional, probabilistic, correlational, and combinatorial reasoning. Students attending the different sections of study had significantly different TOLT performance, older students exhibited significantly better TOLT performance than younger ones, and boys performed significantly better on TOLT than girls did. The “rate” of development was, however, different for different reasoning modes and differences in school achievement between boys and girls did not tap differences in TOLT performance. Regression analysis showed that section of study, gender, grade level, and measures of school achievement contributed significantly to the prediction of TOLT performance. Factor analysis of performance on the ten TOLT items (two items from each reasoning mode) produced a two- and three-factor solution for the sample of boys and the sample of girls, respectively. The results indicate that different theoretical perspectives should be considered when evaluating cognitive development and that learning environments conducive to cognitive growth need to be designed and implemented. 相似文献

The Test of Energy Concepts and Values (TECV) was developed to assess knowledge about and attitudes towards energy for grades 9–12. The TECV, a modification of the Energy Knowledge and Attitude Test, 1 See: National Assessment of Educational Progress. Energy knowledge and attitudes: a national assessment of energy awareness among young adults. Denver, CO: Education Commission of the States, 1978. consisted of 35 knowledge and 39 attitude items. The reliability for the attitude and knowledge sections was 0.70 and 0.76, respectively. Factor analysis was done for the attitude and knowledge sections separately. Item comparison showed that TECV students responses were very similar to the young adults response to the National Assessment instrument. 相似文献

ABSTRACTThis paper, describes the design, development, and evaluation of The Test, a theory-based mobile game prototype designed to promote HIV testing by providing information and influencing motivations, and behavioral intentions among YMSM. The Test was designed using embedded design, first described by Kaufman & Flanagan (2015), which diverges from traditional “educational game” design strategies by mixing on-message content with nonfocal content, in an attempt to make the overall experience more approachable and engaging. One challenge of embedded design is that it targets attitudes and actions that are not always proximate to a particular behavior. Games with embedded content forgo explicit takeaways, and their possible distal effects present a challenge to traditional tests of efficacy. The benefit of embedded design, however, is that its holistic or ecological design approach (which considers feelings, emotions, affects, social relations, and connections to broader communities) stands in close alignment with the social-ecological model. 相似文献

This study examines the institutional affiliations of authors who have published in the three major journals of School Psychology and two additional journals started recently in the field between January, 1985, and July, 1991. The specific journals examined were Psychology in the Schools, Journal of School Psychology, and the School Psychology Review. These journals comprise the primary research outlets in School Psychology. In addition, papers published in Professional School Psychology and the Journal of Psychoeducational Assessment were also included in the analysis because these represent relatively new publication outlets for School Psychology. Findings regarding institutional productivity are compared with those obtained from previous studies in this area. 相似文献

This pilot study investigated how a brief professional development session on the science of learning impacted teachers' attributions of usefulness to both scientific and performative concepts about teaching. Ratings were collected from teachers attending five events across the United Kingdom (N = 585) before and after receiving a 90‐min training session. Initial ratings of scientific concepts were positively correlated with age, while initial ratings of performative concepts were negatively correlated with years of experience. Immediately following professional development, the value teachers attributed to scientific concepts for understanding their practice increased, while their valuing of performative concepts decreased. A follow‐up study with a subsample (N = 153) revealed the impact was reduced but persisted 6–12 weeks later. Results are discussed in terms of the potential for a scientific understanding of learning to empower educators as expert professionals. 相似文献

Metric scale is an important concept taught as part of science curricula across different countries. This study explored metric and relative (body-length) scale concepts of inservice (N?=?92) and preservice (N?=?134) teachers from Austria, and Taiwan, and their concepts were compared with those of teachers from the USA. Participants completed three assessments: the Scale Anchoring Objects (SAO), Scale of Objects Questionnaire (SOQ), and a subsample of participants were interviewed with the Learning Scale Interview. A Rasch analysis was conducted with the SAO and SOQ and results showed that the Rasch model held for these assessments, indicating that there is an underlying common dimension to understanding scale. Further analyses showed that accuracy of knowledge of scale measured by the SAO and SOQ was not related to professional experience. There were significant differences in teachers’ accuracy of scale concepts by nationality. This was true for both metric and body-length SAO assessments. Post hoc comparisons showed that the Austrian and Taiwanese participants were significantly more accurate than the US sample on the SAO and SOQ. The Austrian participants scored significantly higher than the US and the Taiwanese participants. The results of the interviews showed that the Taiwanese experienced teacher participants were more likely to report learning size and scale through in-school experiences than the Austrian or the US participants. US teachers reported learning size and scale most often through participating in hobbies and sports, Taiwanese teachers reported learning scale through sports and reading, and Austrian teachers most often noted that they learned about scale through travel. 相似文献

Spatial visualization, the ability to mentally rotate three-dimensional (3D) images, plays a significant role in anatomy education. This study examines the impact of technical drawing exercises on the improvement of spatial visualization and anatomy education in a Neuroscience course. First-year medical students (n = 84) were randomly allocated into a control group (n = 41) or art-training group (n = 43). Variables including self-reported artistic drawing ability, previous technical drawing experience, or previous anatomy laboratory exposure were gathered. Participants who self-identified as artistic individuals were equally distributed between the two groups. Students in the art-training group attended four 1-hour sessions to solve technical drawing worksheets. All participants completed two Mental Rotations Tests (MRT), which were used to assess spatial visualization. Data were also collected from two neuroscience written examinations and an anatomical “tag test” practical examination. Participants in the art-training and control groups improved on the MRT. The mean of written examination two was significantly higher (P = 0.007) in the art-training group (12.95) than the control group (11.48), and higher (P = 0.027) in those without technical drawing experience (12.44) than those with (11.00). The mean of the anatomical practical was significantly higher (P = 0.010) in those without artistic ability (46.24) than those with (42.00). These results suggest that completing technical drawing worksheets may aid in solving anatomy-based written examination questions on complex brain regions, but further research is needed to determine its implication on anatomy practical scores. These results propose a simple method of improving spatial visualization in anatomy education. 相似文献

Three-dimensional (3D) digital anatomical models show potential to demonstrate complex anatomical relationships; however, the literature is inconsistent as to whether they are effective in improving the anatomy performance, particularly for students with low spatial visualization ability (Vz). This study investigated the educational effectiveness of a 3D stereoscopic model of the pelvis, and the relationship between learning with 3D models and Vz. It was hypothesized that participants learning with a 3D pelvis model would outperform participants learning with a two-dimensional (2D) visualization or cadaveric specimen on a spatial anatomy test, particularly when comparing those with low Vz. Participants (n = 64) were stratified into three experimental groups, who each attended a learning session with either a 3D stereoscopic model (n = 21), 2D visualization (n = 21), or cadaveric specimen (n = 22) of the pelvis. Medical and pre-medical student participants completed a multiple-choice pre-test and post-test during their respective learning session, and a long-term retention (LTR) test 2 months later. Results showed no difference in anatomy test improvement or LTR performance between the experimental groups. A simple linear regression analysis showed that within the 3D group, participants with high Vz tended to retain more than those with low Vz on the LTR test (R2 = 0.31, P = 0.01). The low Vz participants may be cognitively overloaded by the complex spatial cues from the 3D stereoscopic model. Results of this study should inform resource selection and curriculum design for health professional students, with attention to the impact of Vz on learning. 相似文献

In British Columbia, Canada, two population‐based databases have been linked at the level of the individual child: the Early Development Instrument, a Kindergarten school readiness measure; and the Foundation Skills Assessment, a Grade Four academic assessment. Utilising these linked data, we explored the early school readiness, literacy, and numeracy outcomes of a province‐wide study population of children with special needs (N = 3677) followed longitudinally from Kindergarten to Grade Four. In particular, we explored the categories of special needs among our study population. In addition, we investigated the Kindergarten school readiness and Grade Four literacy and numeracy outcomes of children with special needs. We also explored the Grade Four literacy and numeracy outcomes of children with special needs who were ‘not school ready’ at Kindergarten. Finally, we identified the categories of special needs of children who participated in the Kindergarten data collection, but were missing literacy and numeracy scores at Grade Four. Future directions are discussed. 相似文献

The purpose of this study was to investigate students' use of visual imagery and its relationship to spatial visualization ability while solving mathematical word problems. Students with learning disabilities (LD), average achievers, and gifted students in sixth grade (N = 66) participated in this study. Students were assessed on measures of mathematical problem solving, visual imagery representation, and spatial visualization ability. The results indicated that gifted students performed better on both spatial visualization measures than students with LD and average-achieving students. Use of visual images was positively correlated with higher mathematical word-problem-solving performance. Furthermore, the use of schematic imagery was significantly and positively correlated with higher performance on each spatial visualization measure; conversely, it was negatively correlated with the use of pictorial images. 相似文献

Spatial thinking, an important component of cognition, supports academic achievement and daily activities (e.g., learning science and math; using maps). Better spatial skills are correlated with more spatial play and more parental attention to spatial concepts. Tested here was whether informing mothers about spatial thinking and ways to encourage it would increase the spatial guidance they provide to their preschool children (N = 41; M = 5.23 years) during dyadic block play. Mothers given such instructions indeed produced more spatial language and spatial guidance than mothers asked to play as usual. In instructed dyads, children also used more spatial language; both mothers and children engaged in less pretend play. Findings offer support for designing interventions to encourage parents to foster their children's spatial skills. 相似文献

The present study investigates the relation between spatial ability and visuo-spatial and verbal working memory in spatial text processing. In two experiments, participants listened to a spatial text (Experiments 1 and 2) and a non-spatial text (Experiment 1), at the same time performing a spatial or a verbal concurrent task, or no secondary task. To understand how individuals who differ in spatial ability process spatial text during dual task performance, spatial individual differences were analyzed. The tasks administered were the Vandenberg and Kuse [Vandenberg, S. G., & Kuse, A. R. (1978). Mental rotation, a group test of three-dimensional spatial visualization. Perceptual and Motor Skills, 47, 599-604.] mental rotation test (MRT) and a reading comprehension task (RCT). Individuals with high (HMR) and low (LMR) mental rotation differed in MRT scores but had similar RCT performance. Results showed that the HMR group, in contrast with LMR counterparts, preserved good spatial text recall even when a spatial concurrent task was performed; however, Experiment 2 revealed a modification of spatial concurrent task performance in LMR as well in HMR group. Overall, results suggest that HMR individuals have more spatial resources than LMR individuals, allowing them to compensate for spatial working memory interference, but only to a limited extent, given that the processing of spatial information is still mediated by VSWM. 相似文献

Using cognitive diagnostic modeling (CDM), this study identified subtypes of mathematics learning disability (MLD) based on children's numerical skills and examined the language and spatial precursors of these subtypes. Participants were 99 MLD children and 420 low achievers identified from 1839 Finnish children (966 boys) who were followed from preschool (age 6) to fourth grade (2007–2011). Five subtypes were identified: the arithmetic fluency deficit only subtype, the counting deficit subtype, the pervasive deficit subtype, the symbolic deficit subtype, and the counting and concept deficit subtype. Different subtypes depended on different constellations of language and spatial deficits. Findings highlight the effectiveness of CDM in identifying MLD subtypes and underscore the importance of understanding the specific deficits and antecedents of the subtypes. 相似文献
