Social marking of cognitive operations. The effect of different social rules

The present study is concerned with assessing whether social marking (i.e. the correspondence between the correct solution of a task and some known social rule) is a mechanism of cognitive progress which depends on specific forms of rule represented in the task material. Results of an experiment on a spatial transformation task (N=sixty-four non-conserving 5–6-year-olds) showed no significantly different levels of cognitive progress for subjects who transformed the spatial arrangement of a classroom or of a theatre. Significant difference emerged only when a deviation from the normally regulated arrangement were represented. In the condition where the deviation concerned the theatre subjects showed the lower level of progress. It was concluded that the beneficial effect of social marking may depend on the form of rule represented. Results were discussed with respect to children’s knowledge of the relative alterability of different types of rules.

Facebook group dynamics: an ethnographic study of the teaching and learning potential for secondary school teachers

ABSTRACT

This study examines the role of social networking sites on the learning processes, teaching practices and professional development of secondary school teachers. By conducting observations and in-depth interviews with active participants, we present an ethnographic study of the Facebook group Teaching ideas secondary education [author’s translation], which is hosted and primarily employed by Flemish teachers. By drawing parallels between the study findings and the theory of affinity spaces we aim to gain greater insight into emerging group dynamics and social informal learning processes. According to respondents, the Facebook group has the potential to address teachers’ needs with respect to the exchange of teaching ideas, experiences and materials. The findings point to a number of emerging developments in the educational landscape, highlighting that social media environments present a new source of inspiration, and combined with a collaborative atmosphere are able to stimulate cross-fertilization, social informal learning processes and self-management and -reflection. We hold these findings up to the light of current education discourses.     

Explaining effects and side effects of school inspections: a path analysis

There are large differences between schools with regard to how they are affected by a school inspection. This study provides quantitative evidence about the extent to which perceived effects and side effects of an inspection are related to the inspection’s judgement on the school, to features of the inspection, and to school features. This study draws on quantitative data collected from 2,202 teachers in Flemish primary and secondary schools that had recently been inspected. Using path analysis, it investigates the existence and strength of relationships between the perceived effects and side effects of inspection, on the one hand, and the perceived inspection quality, the perceived school’s policy-making capacities, and the inspection judgement, on the other hand. The analysis reveals that most effects and several side effects are predominantly explained by the perceived inspection quality. Emotional side effects during inspection are best predicted by the school’s policy-making capacities.

Brain Processes in Mothers and Nulliparous Women in Response to Cry in Different Situational Contexts: A Default Mode Network Study

SYNOPSIS

Objective: In everyday life, parents must respond to and interact with children while in different situational contexts. How situational contexts influence parents’ responses has not been systematically studied. Here we investigated mothers’ versus nonmothers’ neural responses to infant vocalizations in different situations with different task demands. Design: Using fMRI in 21 women (10 mothers), we explored the effects of being distracted by self-oriented (self-referential decisions about personality adjectives) versus goal-oriented (syllabic counting of personality adjectives) tasks while listening to infant cry in comparison with other emotional sounds (infant laughing, adult crying) on the activity of two medial nodes of the Default Mode Network (DMN): the medial prefrontal cortex (MPFC) and posterior cingulate cortex (PCC). Results: In the self-oriented task while listening to infant cry, both mothers and nulliparas showed (weak) activation of the DMN; this response likely reflects a shift of attention from the task to the cry. In the goal-oriented task, mothers, not nulliparas, showed (weak) activation of the DMN; this result is compatible with interference of emotional sounds while attending to a goal-oriented task, an activity that deactivates the DMN. Conclusions: Mothers are prone to process infant cry and emotional sounds and are less distracted from doing so by situational contexts, demonstrating their greater sensitivity to emotional sounds such as cry. By contrast, situational context influenced brain responses to infant sounds in nulliparas.     

Teaching computer programming with PRIMM: a sociocultural perspective

ABSTRACT

Background and Context: Vygotsky's sociocultural theory emphasises the importance of language, mediation, and the transfer of skills and knowledge from the social into the cognitive plane. This perspective has influenced the development of PRIMM (Predict, Run, Investigate, Modify, Make), a structured approach to teaching programming.

Objective: The objective of the study was to find out if using PRIMM to teach programming had an impact on learner attainment in secondary school, and the extent to which it was valuable for teachers.

Method: We evaluated the use of PRIMM in 13 schools with 493 students aged 11-14 alongside a control group, using a mixed-methods approach. Teachers delivered programming lessons using the PRIMM approach for 8-12 weeks. Data were collected via a combination of a baseline test, a post-test to compare control and experimental groups, and teacher interviews.

Findings: Learners performed better in the post test than the control group. Teachers reported several benefits of the PRIMM approach, including that PRIMM helped them to teach effectively in mixed-ability classes, enabling all learners to make progress.

Implications: PRIMM makes a contribution to programming education research by building on previous work in effective pedagogy for teachers, and encouraging the use of language and dialogue to facilitate understanding.     

A learner–centred approach to developing team skills through web–based learning and assessment

In traditional face–to–face classrooms, collaborative learning has been endorsed as an effective pedagogy that fosters skills of analysis, communication and higher order thinking. Increasingly, as online learning environments for tertiary learners make use of course support systems, there is greater recognition of the potential of communications technologies to foster dialogue, networking and team skills among learners. Such skills are now among the recognised core attributes that graduates are expected to develop. In face–to–face classroom students learn the skills of collaboration and teamwork by engaging in tasks defined and supervised by a teacher. In online environments teacher presence is often limited to task definition, management and feedback functions. Team skills and collaboration therefore need to be supported though different pedagogies and processes such as establishing a climate of trust and openness, communication protocols, resolution of conflict and group processes that provide sanctions and support. In this paper we describe an innovative approach to building the skills of decision–making and conflict resolution, leadership and clarity in goal setting and communication. A case study of tertiary learners illustrates how the essential aspects of task definition, resources to support group learning and integrated online assessment foster team skills.
