Teachers Perceptions

This chapter explores prospective computer teachers’ perceptions of and experiences in goal-based scenario (GBS) centered 3D educational game development process. Twenty-six pre-service computer teachers who enrolled in a Design, Development and Evaluation of Educational Software undergraduate course formed the sample of this case study, and they, in groups, developed GBS-centered 3D educational games. The data were collected through GBS evaluation checklists, interviews, and formative evaluations. The findings indicated that the pre-service teachers preferred GBS-centered educational games to traditional educational games. They declared that the most important feature of educational games was their contribution to motivation, attention, and retention. Although the majority of the groups developed their educational games in line with GBS, they had difficulty creating a realistic scenario and mission. Unlike what the literature indicates, one of the group’s formative evaluation results showed that while the second graders prefer realism, the sixth graders prefer more fantasy in the scenario.

The Continuum

The purpose of this study is to develop and implement a study module including scientific inquiry based experiments in the context of the physical phenomenon of friction, and to assess the learning outcomes. The aim is to describe the levels of students’ understanding after instruction as well as to study where learning is situated on the continuum between meaningful and rote learning. This study is a qualitative case study and the participants of the study are sixth graders from a countryside school. The students studied the issue of friction by doing experiments in collaborative small-groups, following the principles of scientific inquiry. The data was collected firstly, by asking the students prior to the teaching intervention to explain what happens in a picture which shows someone slipping, and secondly, by using an open-ended questionnaire after the teaching intervention. Before instruction, students only used their prior experiences and perceptions in their explanations, whereas after it they also utilized the scientific knowledge and concepts which they had learned during the intervention. After instruction, the students’ answers reflected deeper understanding of the phenomenon, and of the five types of learners found, one type reaches the level of meaningful learning. The finding of five types of learners reflects the complexity of students’ understanding.

Mathematics Literacy

This paper analyses Indonesian primary students’ Mathematical literacy in solving PISA like problems. The instruments were administered to 254 sixth graders from five different regions in Surabaya, Indonesia with various social background. There were three contents (quantity, Uncertainty and data, space and shape) and three level problems (High, Medium and Easy) used to develop Mathematics Literacy Test (MLT). Three students’ categories (Good, Middle and Low) were established by cluster analysis methodology. The most students’ challenge on MLT was space and shape as well as uncertainty and data’s content problem. The description of profile of primary students’ mathematical literacy related to MLT are worthy to suggest the design of learning lines for primary students to have more opportunity to learn and solve Mathematics literacy problem.

The Genesis and Internal Dynamics of El Salvador's People's Revolutionary Army, 1970–1976

The 1960S

AbstractUsing interviews with former militants and previously unpublished documents, this article traces the genesis and internal dynamics of the Ejército Revolucionario del Pueblo (People's Revolutionary Army, ERP) in El Salvador during the early years of its existence (1970–6). This period was marked by the inability of the ERP to maintain internal coherence or any consensus on revolutionary strategy, which led to a series of splits and internal fights over control of the organisation. The evidence marshalled in this case study sheds new light on the origins of the armed Salvadorean Left and thus contributes to a wider understanding of the processes of formation and internal dynamics of armed left-wing groups that emerged from the 1960s onwards in Latin America.

Abstract Culture shapes our basic sensory experience of the world. This is particularly striking in the study of religion and psychosis, where we and others have shown that cultural context determines both the structure and content of hallucination-like events. The cultural shaping of hallucinations may provide a rich case-study for linking cultural learning with emerging prediction-based models of perception.

Abstract Hoerl and McCormack demonstrate that although animals possess a sophisticated temporal updating system, there is no evidence that they also possess a temporal reasoning system. This important case study is directly related to the broader claim that although animals are manifestly capable of first-order (perceptually-based) relational reasoning, they lack the capacity for higher-order, role-based relational reasoning. We argue this distinction applies to all domains of cognition.

Abstract Sociocultural developmental psychology can drive new directions in gadgetry science. We use autobiographical memory, a compound capacity incorporating episodic memory, as a case study. Autobiographical memory emerges late in development, supported by interactions with parents. Intervention research highlights the causal influence of these interactions, whereas cross-cultural research demonstrates culturally determined diversity. Different patterns of inheritance are discussed.

Modern polishing, precision machining and microindentation techniques allow the processing and mechanical characterization of ceramics at nanometric scales and within entirely plastic deformation regimes. The mechanical response of most ceramics to such highly constrained contact is not predictable from macroscopic properties and the microstructural deformation patterns have proven difficult to characterize by the application of any individual technique. In this study, TEM techniques of contrast analysis and CBED are combined with stereographic analysis to construct a three-dimensional microstructure deformation map of the surface of a perfectly plastic microindentation on macroscopically brittle aluminum nitride.The bright field image in Figure 1 shows a lg Vickers microindentation contained within a single AlN grain far from any boundaries. High densities of dislocations are evident, particularly near facet edges but are not individually resolvable. The prominent bend contours also indicate the severity of plastic deformation. Figure 2 is a selected area diffraction pattern covering the entire indentation area.
