In this demonstration paper, we present a pedagogical tool called Hintikka's world for showing how artificial agents can reason about higher-order knowledge (an agent knows that another agent knows that...). The system provides famous AI examples such as Muddy children and Russian cards. The system also allows to implement user's own examples via the description of a Kripke model or via its generation by the generic tableau method prover MetTeL2.

Hintikka's World is a graphical and pedagogical tool that shows how artificial agents can reason about higher-order knowledge. In this demonstration paper, we present the implementation of symbolic models in Hintikka's World. They enable the tool to scale, by helping it to face the state explosion, which makes it possible to provide examples featuring real card games, such as Hanabi.

Research has shown that using debate in higher education as a pedagogical tool has effect on promoting higher order and critical thinking (Camp & Schnader, 2010; Ng et al., 2004; Roy & Macchiette, 2005; Ryan & College, 2006). Debate has been implemented in various disciplines with adult learners, such as psychology (Budesheim & Lundquist, 1999), medicine (Koklanaris, Mackenzie, Fino, Arsland, & Seubert, 2008 ), political science (Omelicheva, 2005), marketing (Roy & Macchiette, 2005), accounting (Camp & Schnader, 2010), science & technology (Scott, 2008). Based on the previous studies, students viewed the use of debate as a new and innovative way to teaching and learning, while being more informative, and eye-opening (Kennedy, 2009; Munakata, 2010). The non-traditional method of teaching also increased students motivation and interest level (Munakata, 2010) as it gave a real sense of drama (Roy & Macchiette, 2005, p. 271). However, in teacher preparation, the implementation of debate as a pedagogical tool to promote learning as well as the research on this topic is relatively limited (Erduran, Ardac, & Yakmaci-Guzel, 2006; Ng, Lan, & They, 2004; Munakata, 2010; Sadler, 2006).  This study aims to implement debate as pedagogical tool to enhance pres-service teachers learning on the subject matter and investigate the effect of using debate in teacher training in Singapore context. The following research questions were posed in the study: (1) whether debate stimulated students thinking on the subject matter more than textbook readings and lectures (traditional teacher-directed methods), (2) to which extent students found debate helpful to their learning on the subject matter, (3) to which extent debate helped students to make connections between the subject matter and the real life, and (4) what was the qualitative feedback from students in their learning through the debate activity. Fifty-six pre-service teachers participated in a course evaluation survey to provide feedback on their learning. The results have shown that 83.9% of teachers agree that debate stimulated their thinking more than textbook readings and lectures, while 14.3% of teachers felt neutral, and 1.8% of teachers strongly disagree. Eighty two percent of teachers found debate very helpful to their learning while 16.1% felt neutral. In addition, 80.4% of teachers agree that debate helps them to make connections between the subject matter and the real life experiences while 17.9% of teachers felt neutral. Several observations emerged from students qualitative feedback on using debate in learning. Students expressed that the debate activity helped them to expand the understanding of the subject matter, retention of crucial concepts and knowledge, and comprehension of essential issues on the subject matter. Students felt debate helped them to understand different perspectives, and reduce bias. Some students reported change of their positions and perspectives after the debate. More importantly, many students stated that debate helped them develop critical thinking and higher order thinking skills in comparison to traditional methods.

We investigate the extent to which agents can learn to coordinate on stationary perfect-foresight cycles in a general-equilibrium environment. Depending on the value of a preference parameter, the limiting backward (direction of time reversed) perfect-foresight dynamics are characterized by steady-state, periodic, or chaotic trajectories for real money balances. We relax the perfect-foresight assumption and examine how a population of artificial, heterogeneous adaptive agents might learn in such an environment. These artificial agents optimize given their forecasts of future prices, and they use forecast rules that are consistent with steady-state or periodic trajectories for prices. The agents' forecast rules are updated by a genetic algorithm. We find that the population of artificial adaptive agents is able eventually to coordinate on steady state and low-order cycles, but not on the higher-order periodic equilibria that exist under the perfect-foresight assumption.

Purpose – The study aimed to explore, describe and analyse the design and implementation of clinical simulation as a pedagogical tool in bridging the deficiency of higher order thinking skills among para-medical students, and to make recommendations on incorporating clinical simulation as a pedagogical tool to enhance thinking skills and align the curriculum.   Methodology – A qualitative approach using interpretativedescriptive case study design was utilized in framing the researchstudy. Purposive sampling was used to select 20 final year paramedicalstudents and five teaching staff who participated in thisstudy. Data was collected through direct and participant observation,interviews and document analysis. Thematic analysis using Stake’sCountenance Model was utilized to analyse and present the findings.   Findings – On the basis of these analyses, the study supports that (i) clinical simulation facilitates the infusion of higher order thinking skills; (ii) clinical simulation that uses thinking pedagogy nurtures the development of higher order thinking skills; and (iii) clinical simulation uses higher order thinking modality to promote, understand and transfer learning. While facilitators play a crucial role in engaging learners with higher order thinking modality and make students’ thinking visible by utilizing the use of metacognition and self-regulation abilities, learners become more autonomous, strategic and motivated to apply effort and strategies in a variety of meaningful contexts.   Significance – The findings of this study can assist curriculum managers, college administrators and educators regarding the inclusion of clinical simulation as an instructional approach to enhance higher order thinking skills among para-medical students.

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.

Among the ultra-light elements B, C, N, and O nitrogen is the most difficult element to deal with in the electron probe microanalyzer. This is mainly caused by the severe absorption that N-Kα radiation suffers in carbon which is abundantly present in the detection system (lead-stearate crystal, carbonaceous counter window). As a result the peak-to-background ratios for N-Kα measured with a conventional lead-stearate crystal can attain values well below unity in many binary nitrides . An additional complication can be caused by the presence of interfering higher-order reflections from the metal partner in the nitride specimen; notorious examples are elements such as Zr and Nb. In nitrides containing these elements is is virtually impossible to carry out an accurate background subtraction which becomes increasingly important with lower and lower peak-to-background ratios. The use of a synthetic multilayer crystal such as W/Si (2d-spacing 59.8 Å) can bring significant improvements in terms of both higher peak count rates as well as a strong suppression of higher-order reflections.

The importance of image simulation in interpreting experimental lattice images is well established. Normally, in carrying out the required theoretical calculations, only zero order Laue zone reflections are taken into account. In this paper we assess the conditions for which this procedure is valid and indicate circumstances in which higher order Laue zone reflections may be important. Our work is based on an analysis of the requirements for obtaining structure images i.e. images directly related to the projected potential. In the considerations to follow, the Bloch wave formulation of the dynamical theory has been used.The intensity in a lattice image can be obtained from the total wave function at the image plane is given by: where ϕg(z) is the diffracted beam amplitide given by In these equations,the z direction is perpendicular to the entrance surface, g is a reciprocal lattice vector, the Cg(i) are Fourier coefficients in the expression for a Bloch wave, b(i), X(i) is the Bloch wave excitation coefficient, ϒ(i)=k(i)-K, k(i) is a Bloch wave vector, K is the electron wave vector after correction for the mean inner potential of the crystal, T(q) and D(q) are the transfer function and damping function respectively, q is a scattering vector and the summation is over i=l,N where N is the number of beams taken into account.

Abstract. In the current study, we examined the viability of a multidimensional conception of perceived person-environment (P-E) fit in higher education. We introduce an optimized 12-item measure that distinguishes between four content dimensions of perceived P-E fit: interest-contents (I-C) fit, needs-supplies (N-S) fit, demands-abilities (D-A) fit, and values-culture (V-C) fit. The central aim of our study was to examine whether the relationships between different P-E fit dimensions and educational outcomes can be accounted for by a higher-order factor that captures the shared features of the four fit dimensions. Relying on a large sample of university students in Germany, we found that students distinguish between the proposed fit dimensions. The respective first-order factors shared a substantial proportion of variance and conformed to a higher-order factor model. Using a newly developed factor extension procedure, we found that the relationships between the first-order factors and most outcomes were not fully accounted for by the higher-order factor. Rather, with the exception of V-C fit, all specific P-E fit factors that represent the first-order factors’ unique variance showed reliable and theoretically plausible relationships with different outcomes. These findings support the viability of a multidimensional conceptualization of P-E fit and the validity of our adapted instrument.
