CURRICULUM SEQUENCING AND THE ACQUISITION OF CLOCK-READING SKILLS AMONG CHINESE AND FLEMISH CHILDREN

The present study addresses the impact of the curriculum on primary school children’s acquisition of clock-reading knowledge from analog and digital clocks. Focusing on Chinese and Flemish children’s clock-reading knowledge, the study is about whether the differences in sequencing of learning and instruction opportunities—as defined by the curriculum—result in differences in accuracy and development of clock-reading knowledge. By means of (1) an in-depth qualitative analysis of the Chinese and Flemish mathematics curriculum standards and textbooks and (2) a quantitative analysis of 11,743 students’ accuracy in reading the time, the current study mirrors the differential impact of alternative curriculum designs for primary education. The results of the analyses reveal that Chinese children acquire clock-reading knowledge—for analog and digital clocks—2 years earlier than their Flemish peers, due to a 2-year earlier exposure. Discussing these results, it is argued that the Flemish curriculum tends to underestimate what children are capable of and that clock-reading within the Flemish primary mathematics curriculum builds on dated assumptions and research results. Building on these outcomes, it is argued that curriculum development should be the result of collaborative inquiry involving policy makers, researchers, and teachers.     

Differently structured advance organizers lead to different initial schemata and learning outcomes

Does the specific structure of advance organizers influence learning outcomes? In the first experiment, 48 psychology students were randomly assigned to three differently structured advance organizers: a well-structured, a well-structured and key-concept emphasizing, and a less structured advance organizer. These were followed by a sorting task, a text study phase, and a posttest. The results indicated that differently structured advance organizers lead to different proto-schemata before and different learning outcomes after the text study phase. The second experiment replicated and extended these findings with 53 mathematics students. As in experiment 1, three differently structured advance organizers were used; but to rule out alternative explanations, the sorting task between the advance organizer and the text study phase was omitted. The results showed strong beneficial effects of well-structured advance organizers on near and far transfer tasks. Taken together, both experiments support the claim that the structure of advance organizers has an effect on preliminary schemata and learning outcomes. On a general level, the results indicate that advance organizers can support the generation of proto-schemata and thus can be more than the activation of “existing” concepts in long-term memory. With regard to education, this implies that educators should not only think about whether prior domain-specific knowledge is present, but also about how to scaffold the generation of proto-schemata at the beginning of instruction.     

Teaching impulsive children with arithmetic deficits in special education: a self‐instructional training program

Abstract

Impulsivity is an important and co‐determining factor in the arising of learning difficulties. Impulsive children make many mistakes in arithmetic because of inattention and because they don't use the selfcontrol necessary to correct possible mistakes. In this investigation we examine whether a self‐instructional training program, applied in the teaching of arithmetic, has influences on the impulsivity (measured with help of the MFFT) of pupils who have a quick reaction time and who make many errors. The study involved 52 pupils selected from schools providing special education to children with learning disabilities and educable mentally retarded children. Sixteen of them could be categorized as impulsive children.

The effectiveness of the training program is statistically investigated by means of t‐tests for correlated samples. The results show that training with a self‐instruction strategy can be effectively employed in teaching addition and substraction to educable mentally retarded and learning disabled children with arithmetic deficits. Besides, the impulsive children show after the training a more reflective cognitive style when compared to their cognitive style before the training was started.     

Primary Student-Teachers' Conceptual Understanding of the Greenhouse Effect: A mixed method study

The greenhouse effect is a reasonably complex scientific phenomenon which can be used as a model to examine students' conceptual understanding in science. Primary student-teachers' understanding of global environmental problems, such as climate change and ozone depletion, indicates that they have many misconceptions. The present mixed method study examines Finnish primary student-teachers' understanding of the greenhouse effect based on the results obtained via open-ended and closed-form questionnaires. The open-ended questionnaire considers primary student-teachers' spontaneous ideas about the greenhouse effect depicted by concept maps. The present study also uses statistical analysis to reveal respondents' conceptualization of the greenhouse effect. The concept maps and statistical analysis reveal that the primary student-teachers' factual knowledge and their conceptual understanding of the greenhouse effect are incomplete and even misleading. In the light of the results of the present study, proposals for modifying the instruction of climate change in science, especially in geography, are presented.     

Orally Positioning Older People in Assessment Meetings

It has been demonstrated that persons with dementia may be positioned as less competent than participants of the same age without dementia, and that persons with dementia possibly also are positioned as less competent than other older persons without dementia. In the present study, we aim to explore this further by analyzing Swedish assessment meetings in which needs and preferences are investigated for older persons without dementia. The material consists five audio-recorded assessment meetings, where there were at least two conversational partners present (a spouse and/or a child) and where the older person applying for social services was not diagnosed with dementia. The ages of the older persons ranged from 81 to 88, while the age of the relatives ranged from 46 to 93. The results of the present study demonstrate that older persons without dementia mainly are positioned as competent. However, it may be related to the degree of frailty, because the frailest person in the present study appears to be positioned as less competent than the other participants. The present paper adds to existing knowledge on how professionals in assessment meetings contribute to the positioning of older persons as competent and capable of making decisions. The results of the present article may be useful to promote development of education and training of communication skills for care mangers in assessments. Such training would further ensure that older persons with and without cognitive impairments can be actively involved in the creation and interpretation of their applications for social services.     

Design milieux for learning environments in African contexts

During the years 2002 to 2009, five African settings were used as foundation for designing different learning environments. While the content and target group for each learning environment varied, all of their design settings, or milieux, shared one implicit expectation: the milieu should facilitate the production of a change‐making learning environment. A retrospective qualitative analysis identified a set of 10 common indicators that describe how successful a given setting is as a design milieu for creating learning environments. The study shows that for each design milieu indicator, a milieu can feature success and failure at the same time. The results, novel in their emphasis on the design setting rather than the use setting, can be used for both assessing the prospects of a particular milieu and improving its strengths for design opportunities especially in African or other developing contexts.     

Modeling Instructional Sensitivity Using a Longitudinal Multilevel Differential Item Functioning Approach

Students’ performance in assessments is commonly attributed to more or less effective teaching. This implies that students’ responses are significantly affected by instruction. However, the assumption that outcome measures indeed are instructionally sensitive is scarcely investigated empirically. In the present study, we propose a longitudinal multilevel‐differential item functioning (DIF) model to combine two existing yet independent approaches to evaluate items’ instructional sensitivity. The model permits for a more informative judgment of instructional sensitivity, allowing the distinction of global and differential sensitivity. Exemplarily, the model is applied to two empirical data sets, with classical indices (Pretest–Posttest Difference Index and posttest multilevel‐DIF) computed for comparison. Results suggest that the approach works well in the application to empirical data, and may provide important information to test developers.     

Lower extremity kinematics of athletics curve sprinting

Curve running requires the generation of centripetal force altering the movement pattern in comparison to the straight path run. The question arises which kinematic modulations emerge while bend sprinting at high velocities. It has been suggested that during curve sprints the legs fulfil different functions. A three-dimensional motion analysis (16 high-speed cameras) was conducted to compare the segmental kinematics of the lower extremity during the stance phases of linear and curve sprints (radius: 36.5 m) of six sprinters of national competitive level. Peak joint angles substantially differed in the frontal and transversal plane whereas sagittal plane kinematics remained unchanged. During the prolonged left stance phase (left: 107.5 ms, right: 95.7 ms, straight: 104.4 ms) the maximum values of ankle eversion (left: 12.7°, right: 2.6°, straight: 6.6°), hip adduction (left: 13.8°, right: 5.5°, straight: 8.8°) and hip external rotation (left: 21.6°, right: 12.9°, straight: 16.7°) were significantly higher. The inside leg seemed to stabilise the movement in the frontal plane (eversion–adduction strategy) whereas the outside leg provided and controlled the motion in the horizontal plane (rotation strategy). These results extend the principal understanding of the effects of curve sprinting on lower extremity kinematics. This helps to increase the understanding of nonlinear human bipedal locomotion, which in turn might lead to improvements in athletic performance and injury prevention.
