Grouping of Pupils in Secondary School Classrooms: Possible Links between Pedagogy and Learning

Pupil groupings within classrooms are a constant social pedagogic factor which effect participation and learning. The grouping of pupils provides a dynamic relationship between learning tasks and the classroom context within which learning takes place. This paper explores types of pupil groupings found in secondary school classrooms related to themes of group size and composition, learning task, group interaction and teacher presence. The paper questions how classroom groupings may be related to the circumstances that promote or inhibit school learning. Previous studies concerning classroom grouping in secondary schools have been dominated by ability or attainment level of the child. The approach and review presented in this study advances a new and more extensive understanding of social pedagogic activity within classrooms. Empirically, a novel classroom “mapping” method with follow-up questions for teachers was used to identify within-class grouping characteristics of children aged 12 and 15 years (in school Years 7 and 10), across curriculum subjects (English, mathematics, science and humanities) in secondary schools. Maps were drawn for 250 classrooms and explained by teachers from 47 schools in England. Results identified that a variety of groupings were found in most classes. Use of particular groupings related to phase of lesson and, to some extent, curriculum. The results showed: little pedagogic association with learning task or interaction; teacher presence associated with control of knowledge; and group composition dominated by stereotypical adolescent friendships. Discussion considers the social pedagogic potential of grouping (with regard to relational capital), control of knowledge and social structure of the classroom attributed to the teacher, and patterns of grouping that may be associated with polarisation in the classroom. *Research reported was part of the GRIS (The Nature and Use of Within Class Groupings in Secondary Schools) project funded by the ESRC, grant number R000238172.

Competition between rhythmic and linguistic organization in a sentence-rhythm Stroop task

We provide a test of Patel's [(2003 Patel, A. D. (2003). Language, music, syntax and the brain. Nature Neuroscience, 6, 674–681. doi: 10.1038/nn1082[Crossref], [PubMed], [Web of Science ®] , [Google Scholar]). Language, music, syntax and the brain. Nature Neuroscience, 6, 674–681] shared syntactic integration resources hypothesis by investigating the competition between determinants of rhythmic parsing and linguistic parsing using a sentence-rhythm Stroop task. We played five-note rhythm patterns in which each note is replaced with a spoken word of a five-word sentence and asked participants to indicate the starting point of the rhythm while they disregarded which word would normally be heard as the first word of the sentence. In Study 1, listeners completed the task in their native language. In Study 2, we investigated whether this competition is weakened if the sentences were in a listener's non-native language. In Study 3, we investigated how much language mastery is necessary to obtain the effects seen in Studies 1 and 2. We demonstrate that processing resources for rhythmic parsing and linguistic parsing overlap with one another, particularly when the task is demanding. We also show that the tendency for language to bias processing does not require deep knowledge of the language.     

Perceptual visual grouping under inattention: electrophysiological functional imaging

Two types of perceptual visual grouping, differing in complexity of shape formation, were examined under inattention. Fourteen participants performed a similarity judgment task concerning two successive briefly presented central targets surrounded by task-irrelevant simple and complex grouping patterns. Event-related potentials (ERPs) were recorded from 22 scalp electrodes and source current density estimations were conducted for the net response to the task-irrelevant background patterns, using low-resolution electromagnetic tomography (LORETA). Although participants’ subjective reports indicated that neither type of organization induced awareness, electrophysiological results showed they both evoked significant activation in occipital, parieto-temporal and frontal brain areas. Behavioral results demonstrated that only grouping of the simple pattern arose under inattention. In contrast to the complex pattern, the processing of the simple pattern was associated with an initially longer latency and higher activation beginning at 130 ms. These results support the distinction of grouping patterns differing in complexity of shape formation.     

Naughty or nice?: equity, gender and behavior

We review the debate over behavior, gender and classroom placement in ability groups for kindergartners. Using vignettes we vary children’s gender in three ways; male, female, or unspecified gender and also describe them as behaving well, average, or misbehaving. Our aim is to probe how much gender and behavior matter with respect to mock reading group placement. The design allows us to see if depicted behavior affects placement when every vignette child is described as possessing the same, average ability. After reading vignettes that vary gender and behavior, but not ability, respondents are directed to assign the portrayed child to a high, medium or low reading group. While depicted behavior strongly affects reading group placement, gender is not a significant predictor.

多身份追踪中基于表情特征的分组效应

探讨了表情因素作为身份特征对多身份追踪中分组效应的影响。采用多身份追踪范式, 8个客体为表情图片(正性、负性、中性)其中4个为目标, 对45名被试进行了有无眉毛线索对追踪表现影响的测查。实验条件分别为：目标表情与非目标表情完全不相同组(4水平, 简称分组)、目标表情与非目标表情都由两种相同数量的表情混合组成(3水平, 简称配对)与基线组(8个客体表情相同)。发现分组水平的成绩显著优于基线组, 配对水平的成绩显著低于基线组, 并表现出了负性表情的追踪优势; 另外, 有无眉毛线索对追踪表现无显著影响。这一结果说明多身份追踪中存在基于表情特征的分组效应, 负性表情的分组知觉高于正性表情。     

Queuing or sharing? A critical evaluation of the single-bottleneck notion

The model of a single central bottleneck for human information processing is critically examined. Most evidence cited in support of the model has been observed within the overlapping tasks paradigm. It is shown here that most findings obtained within that paradigm and that were used to support the model are also consistent with a simple resource model. The most prominent findings are the millisecond-for-millisecond slope at the left of the RT2-SOA curve, the high RT1-RT2 correlation, the additivity of the effects on RT2 of SOA and of the difficulty of selecting R2, and the washout of the effect of S2 discriminability on RT2 in a dual-task condition. In addition, the asymmetry of the effects of the dual-task requirement on RT1 and RT2 can be accounted for by the resource model provided that it assumes uneven allocation of resources, which is quite reasonable in view of the task asymmetry inherent in the demand characteristics of the paradigm. The same is true for two other findings that appear to support the single-bottleneck model-that in the dual-task condition, the demand of the first task affects equally RT1 and RT2 and that its effect on RT1 is the same as the corresponding effect in the single-task condition. Furthermore, the single-bottleneck model is hard to reconcile with a negative slope at the left of the RT1-SOA curve or a positive slope at the left of the IRI-SOA curve, unless augmented by ancillary assumptions that are yet to be substantiated. Representative data were fit by each of the models using its optimal set of parameters. Both models achieved quite good degrees of fit. It is further argued that since the overlapping tasks paradigm is heavily biased in favor of a speedy reaction to the stimulus that appears first, it is nonoptimal for testing the central bottleneck model. Finally, the bottleneck model is examined in terms of other scientific criteria.     

Connection‐based and object‐based grouping in multiple‐object tracking: A developmental study

Developmental research on Gestalt laws has previously revealed that, even as young as infancy, we are bound to group visual elements into unitary structures in accordance with a variety of organizational principles. Here, we focus on the developmental trajectory of both connection‐based and object‐based grouping, and investigate their impact on object formation in participants, aged 9–21 years old (N = 113), using a multiple‐object tracking paradigm. Results reveal a main effect of both age and grouping type, indicating that 9‐ to 21‐year‐olds are sensitive to both connection‐based and object‐based grouping interference, and tracking ability increases with age. In addition to its importance for typical development, these results provide an informative baseline to understand clinical aberrations in this regard.

Statement of contribution

What is already known on this subject?

• The origin of the Gestalt principles is still an ongoing debate: Are they innate, learned over time, or both?
• Developmental research has revealed how each Gestalt principle has its own trajectory and unique relationship to visual experience.
• Both connectedness and object‐based grouping play an important role in object formation during childhood.

What does this study add?

• The study identifies how sensitivity to connectedness and object‐based grouping evolves in individuals, aged 9–21 years old.
• Using multiple‐object tracking, results reveal that the ability to track multiple objects increases with age.
• These results provide an informative baseline to understand clinical aberrations in different types of grouping.

     

Joint drumming: social context facilitates synchronization in preschool children

The human capacity to synchronize body movements to an external acoustic beat enables uniquely human behaviors such as music making and dancing. By hypothesis, these first evolved in human cultures as fundamentally social activities. We therefore hypothesized that children would spontaneously synchronize their body movements to an external beat at earlier ages and with higher accuracy if the stimulus was presented in a social context. A total of 36 children in three age groups (2.5, 3.5, and 4.5 years) were invited to drum along with either a human partner, a drumming machine, or a drum sound coming from a speaker. When drumming with a social partner, children as young as 2.5 years adjusted their drumming tempo to a beat outside the range of their spontaneous motor tempo. Moreover, children of all ages synchronized their drumming with higher accuracy in the social condition. We argue that drumming together with a social partner creates a shared representation of the joint action task and/or elicits a specific human motivation to synchronize movements during joint rhythmic activity.
