Socioeconomic strata, mobile technology, and education: a comparative analysis

Mobile devices are highly portable, easily distributable, substantially affordable, and have the potential to be pedagogically complementary resources in education. This study, incorporating mixed method analyses, discusses the implications of a mobile learning technology-based learning model in two public primary schools near the Mexico-USA border in the state of Baja California, Mexico. One school was located in an urban slum and the other in a rural village community. Empirical and ethnographic data were collected through a series of achievement tests, observations, surveys, and interviews involving 160 s grade school children recruited by convenience sampling. The general technology infrastructure, distinctive features of mobile learning to supplement literacy development, profound contextual phenomena arising from the two uniquely underserved communities, and social factors possibly influencing the educational experiences are discussed. The findings suggest that students in the rural village, seriously lacking educational resources and technology exposure, may have benefited substantially more from mobile technologies than urban school students possibly due to their relatively higher socio-economic status and higher parental involvement and interest in education. In contrast, there was no evidence of interaction with parental education levels, the experience of teachers or school principals, or the teacher’s perception or preparation of the technology. Overall, the mobile learning technology adoption was rapid, seamless, and actively driven by the students rather than the teacher. The challenges of the phenomenal migratory nature of most families in this unique geographical region are also discussed to benefit future studies.  相似文献   

Assessing and Controlling Acquiescent Responding When Acquiescence and Content Are Related: A Comprehensive Factor-Analytic Approach     

Pere Joan Ferrando  Fàbia Morales-Vives  Urbano Lorenzo-Seva 《Structural equation modeling》2016,23(5):713-725

This article proposes procedures for assessing and controlling acquiescence in personality scales when acquiescence is related to the content that the scale intends to measure. Our proposal is comprehensive in that it can be applied to different item response formats fitted with response models that can be parameterized as factor-analytic models. In the calibration stage, our proposal makes joint use of a balanced scale and a set of markers for acquiescence, and consists of 2 sequential procedures: a direct semirestricted solution, and a restricted solution with minimal identification constraints. In the scoring stage, we discuss how the information given by the acquiescence–content relation can be used to obtain Bayes expected a posteriori scores. The robustness of the direct procedure is assessed both analytically and by simulation. A free, user-friendly program that implements the procedures proposed is made available. Practical issues of use and interpretation are discussed and illustrated with an empirical application.  相似文献   

Improving Academic Performance of Sport and Exercise Science Undergraduate Students in Gross Anatomy Using a Near-Peer Teaching Program

Peer and near-peer teaching programs are common in medical undergraduate courses. However, there are no studies that have investigated the effectiveness of a near-peer teaching program on the academic performance of undergraduate students pursuing sport and exercise science coursework. This study was conducted to analyze the effectiveness of such a program for students who participated in a course on the functional anatomy of the locomotor apparatus. A total of 39 student participants were divided into two groups: students in one group voluntarily attended at least one session of a near-peer teaching program, and students in the other group attended no sessions. The final grade (range 0–100%) was recorded and used as an indicator of academic performance. The final grade of students who attended the near-peer teaching program (69.5 ± 16.0%) was 38.7% higher (P = 0.002, d = 1.06) than those who did not (50.1 ± 20.4%). When the academic performance of the same students was evaluated in another course (exercise physiology) that did not offer a near-peer teaching program, there were no significant differences between the groups (students who attended or did not attend the near-peer teaching program). A significant positive association was found between near-peer teaching program frequency and the number of students approved and not approved in the course (P = 0.041). A significant difference (P = 0.001) was found in the attendance at regular classes between the group who participated in the near-peer teaching program (median: 62 hours; IQR [interquartile ranges]: 4.0 hours) and those who did not (median: 58 hours; IQR: 4.0 hours). Gender was not a moderating factor on academic performance or near-peer teaching program attendance. These results highlight the effectiveness of a near-peer teaching program on the academic performance of students from a sport and exercise science degree program while enrolled in an anatomy course.

Intentional thought dynamics during exercise performed until volitional exhaustion     

Natàlia Balagué  Robert Hristovski  Sergi Garcia  Daniel Aragonés  Selen Razon  Gershon Tenenbaum 《Journal of sports sciences》2015,33(1):48-57

Using a non-linear approach, intentional dynamics of thoughts were examined during constant cycling performed until volitional exhaustion. Participants (n = 12) completed two sessions at 80% W_max. Their (1) intrinsic thought dynamics (i.e., no-imposed thoughts condition) and (2) intentional thought dynamics (i.e., imposed task-unrelated thoughts condition; TUT) were recorded and then classified into four categories: internal and external TUT (TUT-I, TUT-E) and external and internal task-related thoughts (TRT-E, TRT-I). The probability estimates for maintaining each thought category stable, the rate of switching from one category to another, and the entropy dynamics along the testing procedure were assessed and compared through time phase. Friedman ANOVA tests revealed a significant effect of effort increase on thought contents only in the imposed TUT test. While TUT-I probabilities decreased significantly (P < .001) as effort increased, TRT-I probabilities increased (P < .05). Moreover, the entropy to the entire thought dynamics increased at the outset of task performance and decreased upon approaching volitional exhaustion (P < .001). As time spent in constant effort increased, and volitional exhaustion approached, task relatedness (TUT, TRT), direction (internal, external), and entropy of thought contents changed unintentionally providing further evidence for a nonlinear dynamics of attention focus.  相似文献

Fragmented spaces in the urban landscape: A socio-spatial analysis of educational supply in the city of Madrid     

Carlos Bueno  Xavier Bonal 《British Educational Research Journal》2023,49(5):1108-1132

The geography of school choice critically shapes families’ educational opportunities. Residential segregation, social inequalities and the educational marketplace interact in complex ways and produce spatialised educational opportunities for families. This paper analyses the link between these dimensions and how they structure families’ educational opportunities in the city of Madrid. Based on several administrative datasets that capture students’ residential location, their socio-economic position, the schools they attend and the characteristics of school supply, our analysis reveals the uneven spatial distribution of the different school modalities in Madrid, where advantaged families and neighbourhoods have more diversified and socio-economically homogenous nearby schooling options. The results also depict the way the city is spatially divided along a continuum of ‘privileged’ residential and educational assets. The paper reflects on how reforms expanding school choice and diversification of the educational market undertaken by the regional government may have increased the link between residential and school segregation.  相似文献
