Pedagogical templates : a comparative study of higher order reflective making

Schon’s notion of reflection-in-action implies a constructivist process of learning, especially valid in the teaching of professional disciplines such as architecture. Action becomes the instrument of conjecture and learning arises in the context of reflection upon the act. Such a process of interleaving action and reflection constitutes a “higher-order” process of reflective making. Research in design studies has shown that strategies for making differ markedly between professional and novitiate designers. Further, such studies have shown that skilled designers employ past experience and precedents to create context for new problem situations. To address the lack of context in novitiate learning situations, we propose the use of “pedagogical templates” for the promotion of “higher-order” strategies in design learning contexts for supporting beginning design students. We focus on the use of digital media, specifically for the design, implementation and delivery of constructive learning situations. This paper presents the use of a pedagogical template in the creation of constructivist contexts for two complementary courses, a traditional design studio and a computer modelling course at Deakin University. The resulting implications for design learning and the integration of physical and digital forms of making through the use of a pedagogical template are discussed.

Laminated plate elements based on higher-order shear deformation theories

Efficient and accurate finite elements are crucial for finite element analysis to provide adequate prediction of the structural behavior. A large amount of laminated plate elements have been developed for finite element analysis of laminated composite plates based on the various lamination theories. A recent and complete review of the laminated finite elements based on the higher-order shear deformation theories, including the global higher-order theories, zig-zag theories and the global-local higher-order theories is presented in this paper. Finally some points on the development of the laminated plate elements are summarized.

The use of Web 2.0 Technologies to promote higher order thinking skills

During 2007 several independent Victorian secondary schools participated in a study exploring the ways in which the use of learning technologies can support the development of higher order thinking skills for students. This paper focuses on the use of Information and Communications Technologies (ICT) including Web 2.0 technologies for promoting effective teaching and learning in science. A case study methodology was used to describe how individual teachers used ICT and Web 2.0 in their settings. Data included interviews (focus group and individual), questionnaires, monitoring of teacher and student use of smart tools, analysis of curriculum documents and delivery methods and of student work samples. The evaluation used an interpretive methodology to investigate five research areas: Higher-order thinking, Metacognitive awareness, Team work/collaboration, Affect towards school/learning and Ownership of learning. Three cases are reported on in this paper. Each describes how student engagement and learning increased and how teachers’ attitudes and skills developed. Examples of student and teacher blogs are provided to illustrate how such technologies encourage students and teachers to look beyond text science.

Gifted are lifted higher : an exploration of the development of higher order thinking skills of gifted students playing strategy games

Strategy games can provide an opportunity to develop higher order thinking skills in students gifted in mathematics. Extending and engaging gifted students is a demanding task. This paper reports on a twelve-week project undertaken with a group of nine gifted lower secondary school students. These students played and analysed five traditional strategy games. Following this experience, they were asked to create a challenging strategy game of their own. This paper discusses the rationale for the use of traditional strategy games, outlines the methodology employed, explains the selection of specific games and describes the observed improvement in students' higher order thinking skills.

Design of reduced-order scalar functional observers

In the existing literature, the existence conditions and design procedures for scalar functional observers are available for the cases where the observers’ order p is either p=1 or p=(v-1), where v is the observability index of the matrix pair (C,A). Therefore, if an observer with an order p=1 does not exist, the other available option is to use a higher order observer with p=(v-1). This paper shows that there exists another option that can be used to design scalar linear functional observers of the order lower than the well-known upper bound (v-1). The paper provides the existence conditions and a design procedure for scalar functional observers of order 0≤ p ≤2, and demonstrates the presented results with a numerical example.

Estimation of basis frequencies for time-varying SIMO channels : a second-order method

The complex exponential basis expansion model (CE-BEM) provides an accurate description for the time-varying (TV) channels encountered in mobile communications. Many blind channel identification and equalization approaches based on the CE-BEM require precise knowledge of the basis frequencies of TV channels. Existing methods for basis frequency estimation usually resort to the higher-order statistics of channel outputs and impose strict constraints on the source signal. In this paper, we propose a novel method to estimate the basis frequencies for blind identification and equalization of time-varying single-input multiple-output (SIMO) finite-impulse-response (FIR) channels. The proposed method exploits only the second-order statistics of channel outputs and does not require strong conditions on the source signal. As a result, it exhibits superior performance to the existing basis frequency estimation methods. The validity of our method is demonstrated by numerical simulations.

Blind extraction using fractional lower-order statistics

In traditional method to blindly extract interesting source signals sequentially, the second-order or higher-order statistics of signals are often utilized. However, for impulsive sources, both of the second-order and higher-order statistics may degenerate. Therefore, it is necessary to exploit new method for the blind extraction of impulsive sources. Based on the best compression-reconstruction principle, a novel model is proposed in this work, together with the corresponding algorithm. The proposed method can be used for blind extraction of sources which are distributed from alpha stable process. Simulations are given to illustrate availability and robustness of our algorithm.

Techno-literacy and blogging within a formal higher education setting

For the last two decades, higher education institutions have been actively engaged in the use of online technologies with the aim of transforming the ways we teach and learn to improve students’ learning experiences and outcomes. However, despite significant investment in infrastructure and training and a wide-scale uptake of such technologies, the promised transformative effect on student learning is yet to be actualised outside of small pockets of innovation. In this paper, we argue that one of the factors contributing to lack of qualitative large-scale transformation is students’ lack of preparedness and experience in using online tools for academic purposes. Focusing on students’ experience of a learning activity that used blogging to promote critical thinking and reflection, we draw on data from a doctoral study to demonstrate how a techno-literacy framework can be used to analyse the nuances of students’ preparedness to put such technologies to work within a formal higher education setting. We argue that, although contemporary university students are largely operationally literate when using online learning tools, they often lack the cultural and critical skills required to use such technologies in a meaningful way to support powerful learning. We argue that, for online learning technologies to transform learning, students need to be supported to develop these higher order techno-literacies.

Adopting an active learning approach to teaching in a research-intensive higher education context transformed staff teaching attitudes and behaviours

The conventional lecture has significant limitations in the higher education context, often leading to a passive learning experience for students. This paper reports a process of transforming teaching and learning with active learning strategies in a research-intensive educational context across a faculty of 45 academic staff and more than 1000 students. A phased approach was used, involving nine staff in a pilot phase during which a common vision and principles were developed. In short, our approach was to mandate a move away from didactic lectures to classes that involved students interacting with content, with each other and with instructors in order to attain domain-specific learning outcomes and generic skills. After refinement, an implementation phase commenced within all first-year subjects, involving 12 staff including three from the pilot group. The staff use of active learning methods in classes increased by sixfold and sevenfold in the pilot and implementation phases, respectively. An analysis of implementation phase exam questions indicated that staff increased their use of questions addressing higher order cognitive skills by 51%. Results of a staff survey indicated that this change in practice was caused by the involvement of staff in the active learning approach. Fifty-six percent of staff respondents indicated that they had maintained constructive alignment as they introduced active learning. After the pilot, only three out of nine staff agreed that they understood what makes for an effective active learning exercise. This rose to seven out of nine staff at the completion of the implementation phase. The development of a common approach with explicit vision and principles and the evaluation and refinement of active learning were effective elements of our transformational change management strategy. Future efforts will focus on ensuring that all staff have the time, skills and pedagogical understanding required to embed constructively aligned active learning within the approach.

Finding voices: authentic learning online in the field of public communication and citizenship

A creative re-acculturation of teachers and students is occurring in virtual classrooms as traditional learning resources, pedagogy, and technology intersect in unexpected ways. This paper reports on a case of authentic, experiential, and constructivist learning developed for tertiary public relations  students. A subject titled ‘Public Communication and Citizenship’ (PCC) at  Deakin University in Australia asked students to examine the problematic and contentious areas of self interest, persuasion, power, and ethics in  contemporary contexts of mass media and globalisation. Feedback from  those students suggests that, in this case, online teaching strategies  successfully integrated with the total learning environment to achieve  higher-order learning. PCC is one example of PR pedagogy combining  theory and technology to move beyond ‘skilling for jobs’.

Enhancing the creative process for learning in primary technology education

When undertaking design and technology activities, children are provided with opportunities to create solutions to problems in new and innovative ways. The mental processes involved in the generation of new ideas may be enhanced when children’s attention is not focussed and is allowed to wander in a relaxed and uncompetitive environment. Research indicates that the two mental states, generative and non-generative, cannot exist simultaneously. This paper reports on a research project which investigated the impact on children’s thinking when a period of non-focussed thinking became part of the technology process. The results support the previous proposition that a child’s non-generative/analytical mental state needs to give way to a generative state so that a child can be more fully creative. Moreover, from this study that documented children’s ideas during their involvement in a design and technology activity, teachers are urged to provide an incubation period as part of the technological process in the classroom, so that children’s creativity can be fostered.

Effective mathematics learning environments : primary teachers' beliefs and practices

A first priority for changing teaching practice is to make problematic for teachers aspects of their current practice. As part of a project on improving mathematics and science teaching in the middle years of schooling, teachers were asked to rate their practice against components of effective teaching and learning and to rate each of these according to their perceived importance. Findings suggest that primary teachers endorsed the components as representing effective practice, scoring most components higher than their actual practice. Gaps were particularly evident for items relating to challenging students conceptually and higher-order thinking, with these becoming the basis for some of the action planning for change.
