When learning from animations is more successful than learning from static pictures: learning the specifics of change

The results of three meta-analyses show that the effectiveness of learning from animations, when compared to learning from static pictures, is rather limited. A recent re-analysis of one of these meta-analyses, however, supports that learning from animations is considerably more effective than learning from static pictures if the specifics of the displayed changes need to be learned. In order to further validate this finding as well as to clarify the educational strengths and weaknesses of animations and static pictures, an experimental study with three groups was conducted. Overall, 88 university students participated in the study. One group of learners (n?=?30) watched a single picture of a gear mechanism, one group of learners (n?=?28) watched four pictures, and one group of learners (n?=?30) watched an animation. All groups had to identify specific motions and spatial arrangements covered by the gear mechanism. While learners who watched the animation exhibited the best performance with respect to the identification of motions, learners who watched the pictures showed the best performance with respect to the identification of spatial arrangements. The effect sizes are large. The results of the study help to clarify when animations and when static pictures are most suitable for learning.

     

Clarity and coherence of lesson goals as a scaffold for student learning

The article addresses clarity and coherence of lesson goals as a scaffold for student learning. In 13 physics classes video recordings of the introductory lesson of two topics were rated with respect to clarity and coherence of the lesson structure. HLM analyses showed a positive effect of classes with high goal clarity and coherence on the students' reports on supportive learning conditions, self-determined learning motivation and organising learning activities. Over the course of a school year high goal clarity and coherence resulted in a positive competence development. No effect was found for individual interest development.     

The retention and success of under-represented groups in a Bachelor of Education program in New Zealand

For several decades researchers have raised questions regarding factors that enable undergraduate students, particularly those from ethnic minority groups living in low socio-economic areas, to persist with their studies to degree completion. Seeking answers to these questions becomes more urgent as universities around the world enrol increasingly diverse cohorts of students. This article reviews the patterns of participation and success for students enrolled in a Bachelor of Education program at one university, distributed across three different locations and attracting different cohorts of students. This provided the university with a unique opportunity to learn about the retention and success of diverse cohorts, particularly those traditionally under-represented at undergraduate-level study. At least 75% of students in the under-represented groups passed their courses. Surprisingly the pass rates of students at the three campuses were similar, despite dissimilarities in ethnicity, socio-economic status and previous academic success.     

Structural, ecological, and psychosocial variables of schooling and their impact on the development of student's self-concept

This chapter deals with the development of student's self-concept in the school context. Using a Systems approach main categories and structural aspects of self-concept and its relation to other variables in the educational field are described. Self-concept is discussed with regard to an ecological perspective by analyzing its relation to variables like social climate, class-size, and reference norms. Under a developmental perspective it is shown that variables of schooling not only produce quantitative changes of self-concept, but also qualitative changes. As a conclusion an integrative view of self-concept development is presented, according to which four developmental levels are distinguished.     

Summary from The Committee on the Public Libraries in the Knowledge Society

This article describes the strategic and political work in the public library sector in Denmark resulting in a strategy report The Public Libraries in the Knowledge Society, published in 2010. This report provides a framework for understanding the current situation of the libraries and gives recommendations for library leaders and policy makers in the field.     

Sibling negotiations and the construction of literacy events in an urban area of Tanzania

This study presents findings from analyses of naturally occurring literacy events, where children jointly focus on reading and writing letters of the alphabet, illustrating social constructions of learning created through language and embodied action. Video recorded data from two different families living in an urban low-income area in Tanzania is presented to illustrate the findings. The analysis shows how participation frameworks are negotiated in terms of symmetries and asymmetries between younger and older siblings with both older and younger siblings initiating these frameworks: older siblings using different directives to guide the younger child's focus of attention and younger children both following and resisting such strategies.     

Alignment as a Teacher Variable

Essay scores generated by machine and by human raters are generally comparable; that is, they can produce scores with similar means and standard deviations, and machine scores generally correlate as highly with human scores as scores from one human correlate with scores from another human. Although human and machine essay scores are highly related on average, this does not eliminate the possibility that machine and human scores may differ significantly for certain gender, ethnic, or country groups. Such differences were explored with essay data from two large-scale high-stakes testing programs: the Test of English as a Foreign Language and the Graduate Record Examination. Human and machine scores were very similar across most subgroups, but there were some notable exceptions. Policies were developed so that any differences between humans and machines would have a minimal impact on final reported scores.
