Considerando os processos de mudança na sociedade e a demanda por novas formas de trabalhar com o conhecimento no ensino, discute-se um novo caminho metodológico inovador: a Aprendizagem Baseada em Problemas (ABP). Descrevendo suas raízes teóricas, procurou-se identificar os seus princípios orientadores a fim de formar cidadãos críticos e conscientes do mundo em que vivem. Os currículos escolares encontrados na maioria das escolas são multidisciplinares, formados por uma soma de disciplinas isoladas. Isso pode dificultar que os alunos dêem sentido aos conhecimentos adquiridos na escola, separando-os dos conhecimentos da \"vida\". A ABP, por ser um método de ensino que tem como ponto de partida um problema que pode ser relacionado à realidade dos alunos, pode ajudar a conferir sentido aos conhecimentos escolares. Aliada à interdisciplinaridade, a ABP torna-se uma ferramenta importante para tratar de problemas complexos da sociedade na escola. O objetivo desta pesquisa foi verificar se a ABP pode promover a interdisciplinaridade nas aulas de Química no Ensino Médio, utilizando as Ilhas de Racionalidade (IR) como modelo de trabalho interdisciplinar. A partir dos princípios da ABP e das etapas das IR, elaborou-se uma situação de aprendizagem (SApr) explorando o tema \"Tratamento e Gerenciamento de Recursos Hídricos em Grandes Cidades\". Os dados de pesquisa foram coletados em duas turmas do segundo ano do Ensino Médio em uma escola estadual localizada na região metropolitana de São Paulo. Os mapas conceituais elaborados pelos alunos no início e no final da SApr foram o principal instrumento de coleta de dados. Verificou-se que inicialmente os estudantes faziam relações superficiais sobre o assunto abordado na SApr havendo uma maior especialização nessas relações no final do processo, envolvendo conceitos de biologia, geografia e química. Pôde-se observar que problemas que se aproximam da realidade dos alunos, tratados de maneira interdisciplinar, motivam os alunos a aprender de forma mais significativa. / The curricula found in most schools are multidisciplinary, consisting of a sum of isolated disciplines. This can make it difficult for students to give meaning to the knowledge acquired in school, separating them from the knowledge of \"life\". The Problem-based Learning (PBL) is a teaching method that has as its starting point a problem related to the reality of students, increasing the meaning to the contents of scholar disciplines. Allied with interdisciplinary, PBL becomes an important tool to address complex problems of society. The purpose of this study was to determine whether PBL can promote interdisciplinarity during chemistry classes in high school, using the Rationality Islands (RI) as a model for the interdisciplinary work. Based on the PBL principles and the RI stages, a 14- class sequence was set up for discussing \"Treatment and Water Resources Management in Big Cities\". Empirical data were collected in two 2nd-year classrooms of a public high school, located in São Paulo. The concept maps produced by students at the beginning and end of the 14-class sequence were the main option for collecting data. It was found that students made superficial relations about the concepts involved with the subject at the beggining, focusing only on chemistry and facts. On the other hand, the final concept maps showed interdisciplinary relationships involving concepts from biology, geography and chemistry. It was observed that problems that approach the reality of children treated in an interdisciplinary way motivate students to learn more significantly.

Traditional chemistry laboratory courses have a manual consisting of “step-by-step” experiments; instructions are given to complete experiments, requiring minimal information/concepts processing to be successful. This experience leaves students unprepared for the real-world, where critical thinking skills are needed to conduct research. This study focused on building analytical techniques, conceptual knowledge, and critical thinking skills used to solve research problems. A new quantitative chemistry laboratory manual was developed to transition students from traditional to inquiry-based experiments, requiring analytical method development. Data showed students having less difficulty using the new manual (0.8281 average difficulty) on method development exam questions and experiments, compared to the traditional manual (0.600 average difficulty). T-test showed significant difference between item difficulty, p = 0.029. Using null hypotheses, the new laboratory manual led to an increase in students’ conceptual knowledge and research skills. They were able to use their knowledge and skills to successfully solve real-world related problems.

This interpretive study investigated the process of radical change for a collaborative team of investigators in an allied health school at the University of South Australia. Specifically, it investigated the process of developing and implementing a fully-integrated problem-based learning curriculum across the entire undergraduate curriculum for the School of Medical Radiation. The study examined the richness and complexity of the change process for this team of educators over a two year time period. The research builds on understandings of change derived from three main bodies of literature: the school-based educational change literature; the problem-based learning literature; and the organisational change literature. It interweaves knowledge gained from each of these areas to develop a new perspective from which to consider radical educational change in higher education. Much of the previous research into change ignores the participant experience, and particularly the emotional dimension of this experience. This study redresses that gap by exploring the human dimension of the change process. This study has provided an authentic and inclusive representation of participants' experience of radical educational change. It has shown that participants not only undergo considerable cognitive dissonance when implementing major change, they also undergo significant emotional dissonance. Thus, if we are to improve the outcomes of educational innovation, we need to develop change management practices that not only recognise but also support the emotional dimension of the change process.

Medical education aims at forming students’ professional identity. This includes skills and attitudes such as communication and teamwork skills. One of the thesis’ aims is to identify students’ typical difficulties with learning communication skills, and to understand how these affect their identity development. Group discussions of student-patient interviews were video-taped, and selected discussions were transcribed and analyzed. Students had difficulties in establishing trustful relationships with their patients, asking about sensitive topics, responding empathetically, and with applying formal structures to the consultation. Students’ professional identity was supported by peer students’ and teachers’ comments, which created a common language and fostered selfmonitoring abilities. Another aim was to study the relationship between students* attitude towards communication training, group learning, and their self-regulatory skills. In a survey study, established instruments were combined with a new questionnaire. Four medical schools participated – two with traditional and two with problem-based curricula – in Sweden and Germany. Statistical analyses revealed that female students were more positive towards learning communication skills than male students were. Good self-regulatory skills were related to a positive attitude towards group learning and clinical experience before academic studies. It was concluded that early clinical experience benefits students’ selfregulated learning, and promotes a positive attitude towards communication training. Awareness of typical difficulties can facilitate the acquisition of coping strategies. / Medicinsk undervisning syftar till att forma studenternas professionella identitet. Den omfattar färdigheter och inställningar, t.ex. kommunikationsfärdigheter och förmågan att arbeta i grupp. Ett av avhandlingens syften är att identifiera studenternas typiska svårigheter med att lära sig färdighet i läkar-patient kommunikation samt att förstå hur den påverkar identitetsutvecklingen. Gruppdiskussioner av student-patient intervjuer videofilmades, utvalda diskussioner transkriberades och analyserades. Studenterna berättade om svårigheter med att etablera förtroliga relationer med patienterna, att prata om känsliga ämnen, att visa empati och att använda intervjumallen. Den professionella identiten stöttas av studenternas och lärarnas kommentarer, vilka bidrar till ett gemensamt språk och förmågan till själviakttagelse. Andra syftet är att undersöka sambandet mellan studenternas inställningar till kommunikationsfärdigheter och grupparbete, samt deras förmåga till självreglerat lärande. I en enkätundersökning kombinerades befintliga instrument med ett nytt frågeformulär. Fyra medicinska fakulteter deltog: två med traditionella och två med problembaserade undervisningsmetoder, en av varje i Sverige och i Tyskland. Statistiska analyser visade att kvinnliga studenter är, jämfört med manliga, mer positiva till att träna upp kommunikativa färdigheter. Förmågan till självreglerat lärande var relaterad till en positiv inställning till gruppinlärande och till klinisk erfarenhet innan studierna påbörjas. Slutsatsen är att tidig klinisk erfarenhet fostrar självstyrt lärande och en positiv inställning till kommunikationsträning. Medvetenhet om typiska svårigheter kan underlätta för studenter att anamma strategier att hantera dessa.

The main purpose of this study was to design and develop a suitable and authentic online case-based learning environment for the classroom management course and to investigate the preservice teachers&rsquo / learning experience in this environment specifically in terms of problems solving skills, motivation, study habits and self-confidence. Having this purpose in mind, action research method in the form of qualitative research methodology was conducted. The main characteristic of the action research is its active and practical nature. Action research has a spiral structure and continues through action cycles. In present study, three action cycles were conducted in a spiral process. The participants of the study were 32 Elementary Science Education students (7 males and 25 females) who were third-year and enrolled classroom management course. Before the implementation, the researcher analyzed current case-based learning environments and methods in teacher education and developed the first version of the VOCABLE. During the implementation the researcher, as the assistant instructor of the course, led VOCABLE practices and made necessary revisions on VOCABLE. Through action cycles data were collected by group interviews, personal interviews, video records of the implementations, expectation and evaluation questionnaires, VOCABLE logs and, electronic posts. The data were analyzed by using descriptive and content v analysis techniques. Results showed that VOCABLE solved the preservice teachers practice problem in classroom management course. Specifically, VOCABLE contributed preservice teachers&rsquo / problem solving abilities, motivation and self-confidence. Also it helped them to be used to teaching profession. On the other hand VOCABLE did not affect their study habits.

Medical schools have been reviewing their curricula to prepare caring and competent health professionals in the midst of a knowledge and technology explosion. The implementation of problem-based learning curricula signalled attempts to make learning more significant, based on constructivist perspectives that emphasise social interaction for meaning making and understanding. Available literature suggests that learning in PBL should be assessed by authentic, contextual real-life tasks that support and encourage students’ learning. To this end, the Nelson R. Mandela School of Medicine implemented the progress examination (PE) to complement the aims of Curriculum 2001 (C2001). The potential formative function of the PE was specifically appealing in terms of allowing for the development of reflective, self-directed and deep learning. Early explorations revealed an apparent mismatch between the aims of C2001, the expectations of stakeholders and their experiences with the PE at the site and these resulted in a number of adaptations to the examination. Cognisant of the influence of assessment on students’ learning, this study sought to examine whether the educational principles governing the implementation of C2001 also informed the implementation and adaptations of the PE. Using a qualitative case study methodology, the study investigated stakeholders’ understandings of the PE and its goals and the lived experiences of its implementation as a suitable tool to assess students’ cognitive learning. In addition, the study also investigated the possible factors that influenced the reform. Findings suggest that the PE was not suitable to assess students’ learning in C2001. Despite the perceptions of a strong educational need for curriculum reform and the apparent suitability of the PE, some members of staff lacked understanding, skill and confidence to apply and implement its aims. Staff failed to apply transformative practices of teaching and learning, while the principles of the PE and C2001 were not well diffused through the organisation. Members of staff expected the PE to differentiate between high and low performing students, while students came to regard the examination as just another hurdle in an already hostile learning environment. Factors such as the unstable and poor leadership, the restructuring of the health and education sectors, impacted on the implementation of the reform. Curriculum and assessment reform is challenging for students and lecturers, requiring the transforming institution to actively prepare and support stakeholders in a conducive educational climate. This case study highlights the need for comprehensive planning for effective and sustained curriculum reform. Collaborative strategies and educational systems should be sought and implemented to sustain conceptual and practical reform. / Thesis (Ph.D.)-University of KwaZulu-Natal, Durban, 2009.

This study explores problem-based learning (PBL) as a form of pedagogy, and its interrelationships with the students, staff members and institution of the Medical Faculty at the University of KwaZulu-Natal. Little has been written previously about the interaction of student diversity and resource-constrained circumstances with PBL. I investigate perceptions and experiences of PBL as a pedagogic strategy, using Bernstein's theories of classification and framing as an organising framework. I draw also on his writings on discourses and knowledge structures and the pedagogic device. Within an interpretive methodology, I use three methods to generate data. I analyse numerically the test marks of a cohort of 202 students over three years for demographic influences on pedagogic engagement. I explore in semi-structured interviews the perceptions and experiences of PBL of 19 students and 6 staff members, and relate these to Faculty documents; I analyse these sources thematically in order to describe the roles of student, teacher and institution. These perceptions and experiences I then examine according to the eight elements of Bernstein's classification and framing. A number of contradictions emerge: between PBL theory, echoed by Faculty documents on one hand, and staff/student perceptions and experiences on the other; between staff members and students at some points but not at others; between high-achieving and low-achieving students; between different respondents' under-standings of "integration". Some demographic characteristics prove on analysis to be highly significant influences while others, counter-intuitively, are not. Bernstein's theories about knowledge structures are pertinent to the tensions revealed. Medicine has thought of itself as akin to the pure sciences – implying a hierarchical structure in which all knowledge aggregates towards a point of abstraction. However, the structure and function revealed by respondents suggests a horizontal knowledge structure, in which disciplinary knowledge is kept distinct. Students and teachers thus struggle to integrate areas of knowledge that are inherently discrete. In terms of Bernstein's "pedagogic device", some students are able to discern PBL's implicit rules of engagement, while others are not. Consensus on medicine‟s knowledge structure might settle ambiguities and help PBL achieve its potential as a complex pedagogy in a complex field. / Thesis (Ph.D.)-University of KwaZulu-Natal, Durban, 2012.

Factors associated with heterogeneous complementation of students’ prior knowledge levels and learning roles and the homogeneity of social interaction relationship were simultaneously considered in the genetic algorithm-based optimized group formation scheme. In this paper, a quasi-experimental research method is employed to assess the effects of three different group formation schemes on the learning performance, interaction, collective efficacy, and group cohesion in collaborative problem-based learning environment. Eighty-three students in three different sixth-grade classes in an elementary school in New Taipei City were invited to participant in the experiment and were randomly divided into three groups: the experimental group, which adopts genetic algorithm-based optimized group formation scheme, and two control groups, one is randomly grouped; while the other allows students group themselves. Learners in these three groups all use collaborative problem-based learning system (CPBL) to perform collaborative problem-based learning activities. Learning performance, interaction, group efficacy and group cohesion evaluation are applied to analyze the learning process and interaction among learners in these three groups. Finally, a semi-structured interview is supplemented to validate the variation of these three different group formation schemes in learning performance, interaction, group efficacy and cohesion. The result showed that the genetic algorithm-based optimized group formation scheme helps students promote learning performance and provides positive effects on peer interaction in collaborative problem-based learning. Three group learners adopting different group formation schemes for collaborative problem-based learning show significant difference on group effectiveness and group cohesion. The satisfaction of learners adopting genetic algorithm-based optimized group formation scheme for collaborative problem-based learning reached a nearly agreed standard.

Our paper presents some preliminary observation from a collaborative exploratory study linking mathematics, science and reading within a technology enhanced problem-based learning scenario conducted at one French Canadian Elementary and Middle School. Presented in a form of dialogue between teacher and researcher, our findings give some meaningful insight in how an innovative mathematics teaching can be developed and implemented using a real-world problem solving. Instead of a traditional presentation of material about lighting up homes, participating mathematics, science and French teachers were working collaboratively with the ICT integration mentor and two university professors helping students investigate a problem from various perspectives using a variety of cognitive and metacognitive strategies, discussing and sharing the finding with peers and presenting them to a larger audience using media tools. Our preliminary results may prompt further investigation of how innovation in teaching and learning can help students become better critical thinkers and scientifically empowered citizens.
