The aim of the present study was to identify children’s conceptions of learning mathematics and to assess the identified conceptions.
Children’s conceptions are identified by interviewing 73 grade 5 students in Taiwan. The interviews are analyzed using qualitative
data analysis methods, which results in a structure of 5 major conceptions, each having 2 subconceptions: constructivist (interest and understanding), interpretivist (liberty and innovation), objectivist (academic goal and perseverance), nativist (confidence and anxiety (reverse)), and pragmatist (vocational goal and application). The conceptions are assessed with a self-developed questionnaire, titled “the Conception of Learning Mathematics Questionnaire”
(CLMQ), which is administered to 513 grade 5 students in Taiwan and examined with a reliability measure, confirmatory factor
analysis, and correlations with 2 criteria: mathematics achievement and approaches to learning mathematics. The results show
that the CLMQ has desirable internal consistency reliability and construct validity. The conceptions are also sensibly in
relation to the 2 criteria, suggesting that the CLMQ is a valid measure for evaluating the quality of children’s learning
mathematics in relation to teaching contexts. 相似文献

Developing reading behaviours in early childhood is essential for later reading comprehension. This study explored how peer buddy reading could potentially support emergent readers’ engagement with reading behaviours. Across 40 buddy‐reading events, 14 preschoolers (ages 4.0–5.5 years) produced 1,359 conversation turns, which were coded for a variety of reading behaviours including comprehension, thematic vocabulary use and concepts about print. Using statistical discourse analysis, we examined how children's engagement with reading behaviours was related to their buddies’ engagement with reading behaviours in subsequent conversation turns during buddy‐reading events. Findings suggest that some of preschoolers’ reading behaviours, such as literal text representation, inferential text interpretation, character development and comprehension monitoring were related to their buddies’ engagement with reading behaviours; others, such as vocabulary and concepts about print, were not. Implications include that buddy reading can be used to support preschoolers’ engagement with some reading behaviours, such as certain aspects of comprehension. 相似文献

Adapted from Chang et al.'s (2006) models, this study examines factors that influence adoption and non-adoption of social network sites (SNS) in adopters (Continuers, Discontinuers) and non-adopters (Potentials, Resistors). Chi-square and t-test were used to analyze the survey data of Singapore's working adults and Internet users (N =222). The findings reveal innovation characteristics (relative advantage, compatibility, complexity) and perceived popularity differ significantly in three pairs of adopter categories. Results show Continuers and Potentials are concerned more about image than Discontinuers and Resistors, while technology cluster differs between adopter vs. non-adopter and Continuers vs. Discontinuers. Moreover, the study suggests younger people tend to adopt SNSs, females continue to use SNSs more, and potential SNS users are more innovative. Lastly, a regression model to forecast the adoption of SNSs is proposed in which age, compatibility, technology cluster, and perceived popularity are predictors. 相似文献

The purpose of this study was to examine the relationship between student understanding of the nature of science and their problem-solving strategies. Six hundred and twenty Year 8 students in Taiwan twice completed two conceptual problem-solving tests and a questionnaire on the nature of science. Four of these students were selected for follow-up interviews. The result of stepwise multiple regression indicated that the subscale on the nature of the scientific method consistently appeared as the best predictor for student problem-solving ability, explaining about 22% of the variance. It was also found that problem-solving strategies were more conceptually based for students that were high scorers on the nature of science survey. 相似文献

The use of computerized adaptive testing algorithms for ranking items (e.g., college preferences, career choices) involves two major challenges: unacceptably high computation times (selecting from a large item pool with many dimensions) and biased results (enhanced preferences or intensified examinee responses because of repeated statements across items). To address these issues, we introduce subpool partition strategies for item selection and within-person statement exposure control procedures. Simulations showed that the multinomial method reduces computation time while maintaining measurement precision. Both the freeze and revised Sympson-Hetter online (RSHO) methods controlled the statement exposure rate; RSHO sacrificed some measurement precision but increased pool use. Furthermore, preventing a statement's repetition on consecutive items neither hindered the effectiveness of the freeze or RSHO method nor reduced measurement precision. 相似文献

ABSTRACTMales (n = 29) and females (n = 34) performed vertical jumps. Jump height was estimated from force platform data using five numerical methods and compared using intraclass correlation (ρ), and linear and rank regression standard error of estimate (SEE). Take-off velocity plus center of mass height at take-off and mechanical work methods were identical (ρ = 1.000) with small linear (SEE < 0.0001 cm) and rank order (SEE = 0) error. Integrating acceleration to displacement was nearly identical (ρ > 0.999), with small linear (SEE = 0.1 cm) and rank order (SEE < 1) errors compared to the above methods. Take-off velocity (ρ = 0.517) and flight time (ρ = 0.573) estimates were less than all other methods and had large linear (SEE ≥ 2.1 cm) and rank order (SEE > 4) errors. Take-off velocity and flight time methods should be avoided due to systematic and random error. 相似文献
