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 groups. Moreover, within-culture comparisons were made in terms of gender. The results showed that, first, the SLSE instrument was valid and reliable for measuring the Singaporean and Taiwanese students' SLSE. Second, through a two-way multivariate analysis of variance analysis (nationality by gender), the main result indicated that the SLSE held by the Singaporean eighth graders was significantly higher than that of their Taiwanese counterparts in all dimensions, including ‘conceptual understanding and higher-order cognitive skills’, ‘practical work (PW)’, ‘everyday application’, and ‘science communication’. In addition, the within-culture gender comparisons indicated that the male Singaporean students tended to possess higher SLSE than the female students did in all SLSE dimensions except for the ‘PW’ dimension. However, no gender differences were found in the Taiwanese sample. The findings unraveled in this study were interpreted from a socio-cultural perspective in terms of the curriculum differences, societal expectations of science education, and educational policies in Singapore and Taiwan.  相似文献

A comparison of cognitive, academic, and linguistic profiles for 74 college students with learning disabilities and 37 college students without learning disabilities resulted in significant differences in achievement for reading, writing, listening, and speaking. No significant differences were found for gender or the presence of a Verbal-Performance split in cognitive ability. Instruments for measuring academic and linguistic skills were similar in their ability to classify students with and without learning disabilities. These findings support the importance of using measures of multidimensional attributes, including language, for making decisions concerning the criteria for learning disabilities.  相似文献

Science learning self-efficacy could be regarded as a multi-factor belief which comprises different aspects such as cognitive skills, practical work, and everyday application. However, few studies have investigated the relationships among these factors that compose science learning self-efficacy. Also, culture may play an important role in explaining the relationships among these factors. Accordingly, this study aimed to investigate cultural differences in science learning self-efficacy and examine the relationships within factors constituting science learning self-efficacy by adopting a survey instrument for administration to students in the U.S. and Taiwan. A total of 218 university students (62.40% females) were surveyed in the U.S.A, and 224 university students (49.10% females) in Taiwan were also invited to take part in the study. The results of the structural equation modelling revealed cultural differences in the relationships among the factors of science learning self-efficacy. It was found that U.S. students’ confidence in their ability to employ higher-order cognitive skills tended to promote their confidence in their ability to accomplish practical work, strengthening their academic self-efficacy. However, the aforementioned mediation was not found for the Taiwanese participants.  相似文献

A diagnostic model for large‐scale assessment was applied to TIMSS data to compare mathematics performance of eighth graders from three countries—the US, Singapore, and Israel. Compared were attribute mastery probabilities for content, skills and cognitive processes underlying students’ performance on the 1999 TIMSS‐R mathematics test. Also compared were the proportions of students from the three samples in each of eight hierarchically ordered clusters of knowledge states. The results indicated significant differences in favour of the Singaporean sample on most attributes underlying the test. The results were discussed in light of the cultural context of education in the respective countries.  相似文献

In cognitive diagnostic models (CDMs), a set of fine-grained attributes is required to characterize complex problem solving and provide detailed diagnostic information about an examinee. However, it is challenging to ensure reliable estimation and control computational complexity when The test aims to identify the examinee's attribute profile in a large-scale map of attributes. To address this problem, this study proposes a cognitive diagnostic multistage testing by partitioning hierarchically structured attributes (CD-MST-PH) as a multistage testing for CDM. In CD-MST-PH, multiple testlets can be constructed based on separate attribute groups before testing occurs, which retains the advantages of multistage testing over fully adaptive testing or the on-the-fly approach. Moreover, testlets are offered sequentially and adaptively, thus improving test accuracy and efficiency. An item information measure is proposed to compute the discrimination power of an item for each attribute, and a module assembly method is presented to construct modules anchored at each separate attribute group. Several module selection indices for CD-MST-PH are also proposed by modifying the item selection indices used in cognitive diagnostic computerized adaptive testing. The results of simulation study show that CD-MST-PH can improve test accuracy and efficiency relative to the conventional test without adaptive stages.  相似文献

Lack of knowledge in the conventional use of vocabulary and multiword patterns in one's respective field of expertise causes Taiwanese students to produce academic writing that is markedly “non-nativelike.” This is because Taiwanese students are first and foremost second language readers and often have difficulty “picking up on” the regularly encountered language patterns found in scholarly texts. As one step in determining a solution to this problem, this article reports on a pilot implementation encouraging graduate Taiwanese students for whom English is a foreign language to use self-editing techniques in their own field-specific academic writing by use of a corpus tool. Classroom interviews, draft comparisons, and individual stimulated recall interviews showed a difference in acceptance and success after using the corpus tool (StringNet Navigator) as an aid to self-editing academic English writing. The corpus tool's functions, results of its use by industrial management graduate students for self-editing academic writing, and pedagogical implications are described.  相似文献

The study assessed cognitive and academic performance of children demonstrating teacher-rated ADHD-related symptoms (Inattention [IA] and/or Hyperactivity/Impulsivity [H/I]) in a representative sample of, largely untreated, Greek elementary school students (N?=?923). A battery of tests assessing short-term memory (STM), sustained attention, executive functions (EFs), reading and math skills were administered. Significant deficits in EFs and STM were restricted to the groups of students displaying inattention symptoms and were only marginally elevated among students showing hyperactivity/impulsivity symptoms alone, in comparison to their non-symptomatic peers. A similar pattern of group differences was observed on tests assessing word- and text-level reading skills. Impaired performance on sustained attention tasks was less evident. Among students who manifested inattention symptoms, those who also showed impaired reading skills presented more severe EFs deficits than typically achieving students. Results demonstrated a close link between EFs, other than inhibition and set-shifting, everyday symptoms of inattention, and achievement in math and word-level reading skills.  相似文献

This article describes a collaborative research project by the institutional research group and a team of faculty members at a Canadian university. In response to an increasingly diverse mix of students, the researchers set out to develop an understanding of relationships between student characteristics, categorized as demographic differences, personal attributes and academic preparedness, and student outcomes measured by both grades and student perceptions. Significant differences were found in grades outcomes based on characteristics such as international status, secondary school grades, study habits and writing skills. However, these differences were not evident in student perceptions of course value or learning achievement. This study has important implications for university administrators (recruiting, intake assessment and student support), instructors (understanding of diversity characteristics and how students perceive learning experience) and for students, who can be given an opportunity to better understand how their own personal characteristics might affect their learning experiences and outcomes.  相似文献

The purpose of this study is to investigate the effects of computer-assisted videodisc-based anchored instruction on attitudes toward mathematics and instruction as well as problem-solving skills among Taiwanese elementary students. Results from a t-test indicate a significant main effect on student attitudes toward mathematics. Results from a two-way Repeated Measures ANOVA show that students' problem-solving skills improve significantly with anchored instruction. Results also indicate that all the students benefit from the effects of anchored instruction on their problem-solving performance regardless of their mathematics and science abilities. The findings suggest that video-based anchored instruction provide a more motivating environment that enhanced students' problem-solving skills. This study is significant because it establishes an example of video-based anchored instruction for Taiwanese students and also provides empirical evidence of its effects on affective and cognitive responses among fifth graders in learning mathematics. This study is helpful to educators who want to help students learn to think and learn throughout technology.  相似文献

Cognitive skills are associated with academic performance, but little is known about how to improve these skills in the classroom. Here, we present the results of a pilot study in which teachers were trained to engage students in cognitive skill practice through playing games. Fifth‐grade students at an experimental charter school were randomly assigned to receive cognitive skill instruction (CSI) or instruction in geography and typing. Students in the CSI group improved significantly more than the control group on a composite measure of cognitive skills. CSI was more effective for students with lower standardized test scores. Although there was no group effect on test scores, cognitive improvement correlated positively with test score improvement only in the CSI group. Beyond showing that cognitive skills can be improved in the classroom, this study provides lessons for the future of CSI, including changes to professional development and challenges for scalability.  相似文献

Curriculum content, the issue of what to teach is fundamental. For students with intellectual disabilities (ID), the choice of educational content is crucial in a life span perspective. Curriculum research for this learner group is sparse. Drawing on a curriculum approach, the purpose of this content analytic reviw study is to analyse trends in curricular research, and discuss implications for further curricular research and policy. Curricular research articles from 1994 to 2016 were identified from databases, using systematic search procedures and specific criteria for inclusion and categorisation of the literature. Based on prior review studies, functional life skills and cognitive academic content formed the analytical fulcrum. The results showed that cognitive academic articles had the highest coverage in the literature and showed a steep increase in publication frequency compared to functional life skill articles. If curricular research on functional life skills stagnates, curriculum policy and practice may fail to provide students with ID the skills necessary for social and practical adaption in their communities. A discursive connection to normative curricular frameworks is essential to analyse and guide curricular choices. This article provides analytical insight and directions for future research in the field of curriculum research for students with ID.  相似文献

Little is known about the relative effects of post‐secondary learning services for students with learning disabilities. We compared outcomes for students with learning disabilities who selected to: (1) take an academic learning success course (course‐intervention), (2) have regular individual interventions (high‐intervention) or (3) use services only as needed (low‐intervention). Pre‐ and post‐test comparisons revealed improvements in academic self‐efficacy and academic resourcefulness for students in the course‐ and high‐intervention groups. The course‐intervention group also showed decreases in their failure attributions to bad luck and increases in their general repertoire of learned resourcefulness skills in comparison to the high‐intervention group and had significantly higher year‐end GPAs in comparison to the low‐intervention group. Here we find positive outcomes for students with learning disabilities taking a course that teaches post‐secondary learning and academic skills.  相似文献

English Learners (ELs), students from non-English-speaking backgrounds, are a fast-growing, understudied, group of students in the U.S. with unique learning challenges. Cognitive flexibility—the ability to switch between task demands with ease—may be an important factor in learning for ELs as they have to manage learning in their non-dominant language and access knowledge in multiple languages. We used functional MRI to measure cognitive flexibility brain activity in a group of Hispanic middle school ELs (N = 63) and related it to their academic skills. We found that brain engagement during the cognitive flexibility task was related to both out-of-scanner reading and math measures. These relationships were observed across the brain, including in cognitive control, attention, and default mode networks. This work suggests the real-world importance of cognitive flexibility for adolescent ELs, where individual differences in brain engagement were associated with educational outcomes.  相似文献

QuickSmart is a basic academic skills intervention designed for persistently low-achieving students in the middle years of schooling that aims to improve the automaticity of basic skills to improve higher-order processes, such as problem solving and comprehension, as measured on standardized tests. The QuickSmart instructional program consists of three structured, teacher- or teacher aide-directed, 30-minute, small-group lessons each week for approximately 26 weeks. In this study, 42 middle school students experiencing learning difficulties (LD) completed the QuickSmart reading program, and a further 42 students with LD took part in the QuickSmart mathematics program. To investigate the effects of the intervention, comparisons were made between the reading and mathematics progress of the intervention group and a group of 10 high-achieving and 10 average-achieving peers. The results indicated that although the standardized reading comprehension and mathematics scores of QuickSmart students remained below those of comparison students, they improved significantly from pretest to posttest. In contrast, the standardized scores of comparison students were not significantly different from pretest to posttest. On measures of response speed and accuracy gathered using the Cognitive Aptitude Assessment System (CAAS), QuickSmart students were able to narrow the gap between their performance and that of their high- and average-achieving peers. Implications are drawn regarding the importance of interventions that emphasize the automaticity of basic academic skills for students with learning difficulties.  相似文献

The phenomenon of women engaging in entrepreneurship is expanding and becoming acknowledged as a valuable resource that must be institutionally and socially supported. Through entrepreneurship education, female students, as potential entrepreneurs, can develop and strengthen those skills and behaviours identified as characteristic of successful entrepreneurs. This paper explores four attributes associated with entrepreneurship (creativity, problem management, risk management, and self-confidence) of 1838 undergraduate students from 11 universities in Latin America (Mexico, Argentina, Brazil, Chile, Colombia, Costa Rica, El Salvador, Guatemala, and Uruguay) and one in Spain, used as a control group. By comparing the results for the male and female student population, self-confidence appears as an attribute that is present at the same level in both groups; statistically significant differences were reported for the other three attributes (creativity, problem management, and risk management). Entrepreneurship programmes can utilise such information to strengthen in female students those attributes for successful engagement in entrepreneurial activity.  相似文献
