Developing reflective practice as part of teacher training with the use of critical incidents

100%

Kossakowska-Pisarek S.

nr 55/1

93-106

Preparing thoughtful reflective practitioners has become a common concept in the teacher education literature. Prior educational experiences offer excellent opportunity for students to reflect on authentic teaching examples and provide constructive ways to engage in reflective practice. This study examines critical incidents as a tool for developing reflective thinking skills among teacher trainees (N=11). The research on use of critical incidents for training comprised a questionnaire and group discussions. The instrument used for analyzing critical incidents included personal details, factual information and openended questions concerning reasons for and consequences of the incident, associated emotions, reflections connected with it, lessons from this incident and its implications for the future. Overall, although some crucial issues arose, the technique proved useful for training, and was assessed as positive and valuable by the teacher trainees. Some pedagogical implications were formulated regarding problems with understanding the notion of critical incident, previous training of the teacher trainees and the need for a supportive environment.

Use of wind energy of the ground zone in low individual buildings

100%

Obuchowicz R.

tom nr 57

187--204

The issue of obtaining wind energy in individual construction facilities is associated with a change in the scope of design issues undertaken in the case of high and large-scale buildings. This is due to the limited size of the assumptions, the type of wind devices used and the need to maintain their proper relationship to the function and form of the architectural object, and the need to ensure acceptable energy efficiency in turbulent flow conditions. The currently adopted design approaches, treated as patterns and constituting the starting point in the design process, constitute a correct synthesis of the issues undertaken by the designer, but they do not fully exhaust the issues raised. This article presents a study concept of a residential facility located below ground level and equipped with an installation for obtaining wind energy.

Problematyka pozyskiwania energii wiatru w obiektach budownictwa indywidualnego wiąże się ze zmianą zakresu podejmowanych zagadnień projektowych występujących w przypadku budynków wysokich i wielkoskalowych. Wynika to z ograniczonych rozmiarów założeń, rodzaju stosowanych urządzeń wiatrowych i potrzeby zachowania właściwych ich relacji do funkcji i formy obiektu architektonicznego oraz z konieczności zapewnienia akceptowalnej wydajności energetycznej w warunkach przepływu o charakterze turbulentnym. Przyjęte aktualnie podejścia projektowe, traktowane jako wzorce i stanowiące punkt wyjścia w procesie projektowym stanowią prawidłową syntezę zagadnień podejmowanych przez projektanta, lecz nie wyczerpują w pełni podejmowanej problematyki. W niniejszym artykule przedstawiono koncepcję studyjną obiektu mieszkalnego, zlokalizowanego poniżej poziomu terenu i wyposażonego w instalację do pozyskiwania energii wiatru.

An algorithmic tool for supporting risk and root-cause analysis of critical incidents in Baltic Sea Region ports

100%

Malinowski J.

tom Vol. 10, No. 1

127--136

This paper is both a summarization and extension of [6] and [7], where a stochastic model of interacting operations carried out in a generic Baltic Sea Region port was proposed and analyzed. Each operation involves a number of possible unwanted events (critical incidents) whose instances occur randomly and can cause instances of other events affecting this or other operations. This can lead to a cause-effect chain of events affecting one or multiple operations. The model presented in [6] is somewhat complex, therefore it was downgraded to a simpler, application-oriented version demonstrated in [7], where an algorithm computing the risks of critical incidents is constructed and then applied to a real-life example. The current paper, apart from presenting a method of computing the risks of critical incidents, occurring by themselves or resulting from the cascade effect, also features a method of root-cause analysis of such incidents. First, the formulas for the root-cause probabilities are derived, where such a probability quantifies the likelihood that a critical incident occurring in step h of a cascade was caused by another incident that initiated this cascade. Second, an algorithm computing the root-cause probabilities, based on the derived formulas, is constructed. This algorithm is illustrated by its application to the example given in [7]. The presented results can be used as a tool for fault propagation analysis and fault diagnosis applied not only to a port environment, but to any complex industrial system.
