Improving students’ learning with a mobile augmented reality approach: the EduPARK game
Mobile devices are intensively used by the Portuguese youth in their daily life, but not in school activities. Despite this
gap, research shows that technology can promote students’ learning. This paper comprises a survey study where mobile
learning is analyzed through the eyes of 244 students attending the 2
nd
or 3
rd
Cycles of Basic Education (CBE). The
acknowledged advantages and difficulties of the use of mobile devices for learning, as well as the educational value and
usability of a specific mobile learning strategy, using the EduPARK app and game, were analyzed. Results revealed that
most students owned a mobile device and were able to use them to learn. They had a positive perspective regarding
mobile learning and valued the advantages of being easy to find up-to-date information, motivating for learning and easy
to carry along. Difficulties are related to the use of mobile devices to learn, such as requiring an internet connection, its
slowness, and prohibition of mobile devices in schools. The EduPARK game achieved an average Educational Value
Scale of 83.8 and an average System Usability Scale of 80.2, indicating its high educational value and usability for
students. This paper presents empirical evidence regarding the effectiveness of the integration of mobile game-based AR
approaches in Basic Education to promote students’ learning. It also includes an example of excellent cros-subjects
educational materials that comprises a very useful tool for teachers and students to explore scientific knowledge by
accessing appealing information on biological and historical references of a local urban park.publishe
Science teaching strategies developed in an online community of practice: a case study
Communities of practice (CoP) have been presented in the literature
as potential promoters of the improvement of teaching strategies. However, there is
scarce empirical evidence of that impact, namely in science education. Purpose: This
study aims to present empiric evidence supporting the potential of online CoPs, involving
teachers and researchers, for the development of effective science teaching practices –
considering the literature on science education (SE) regarding strategies that can
effectively promote pupils’ learning. Sample, design and methods: The authors
conducted a single case study: a curricular module developed by a collaborative group of
five teachers and three researchers, which formed a CoP under the Portuguese project
IPEC1
. The CoP members interacted mainly through online communication tools;
therefore, content analysis of the developed lesson plan, and associated teaching
resources, was complemented with evidence from online interactions, as well as
documents produced by the CoP as dissemination papers. Results and conclusions:
The study showed that the CoP developed a field trip combining diversified teaching
strategies, such as learning of contextualized phenomenon, small work group or
questioning, referred in the reviewed literature as effective science teaching strategies.
The results also point to the evolution of the teachers’ practices during their participation
in this CoP. Hence, it provides empirical evidence that supports that online CoP of
teachers and researchers can promote the improvement of science teaching practices. It
also gives a glimpse of possible factors that can contribute to that improvement, which
require further empirical study.publishe

Gestão curricular intencional numa comunidade de prática online
Mestrado em Gestão CurricularUma das vertentes da investigação em Educação em Ciência visa a melhoria
do processo de ensino e aprendizagem. Parece haver uma natural
convergência de interesses entre professores e investigadores que, contudo,
nem sempre se concretiza em formas de trabalho colaborativo. Este
distanciamento entre a investigação e a prática docente foi identificado e tem
sido razão para o desenvolvimento de muitos projectos de investigação, entre
os quais se destaca o projecto “Investigação e Práticas lectivas em Educação
em Ciência: dinâmicas de interacção”, que enquadrou este estudo. O referido
projecto visa contribuir para a articulação entre as práticas educativas e a
investigação em Educação em Ciência. Constituiu-se uma comunidade de
prática online tendo em vista potenciar o desenvolvimento profissional de todos
os envolvidos.
A questão central deste estudo diz respeito às implicações decorrentes do
envolvimento de professores e investigadores numa comunidade de prática
online, ao nível da sua gestão curricular intencional.
Optou-se por uma metodologia de natureza predominantemente qualitativa,
descritiva, exploratória e do tipo estudo de caso único, sendo o caso um grupo
de professores e investigadores do referido projecto. Este estudo
compreendeu duas fases. Na primeira, procedeu-se à selecção do grupo a
analisar, tendo por base os seguintes critérios: a) o índice de sentimento de
comunidade (McMillan & Chavis, 1986); b) a forma de trabalho do grupo; c) a
presença de indicadores de comunidade de prática (Wenger, 1998). Na
segunda fase, procurou-se analisar a gestão curricular intencional realizada
pelo grupo seleccionado ao nível de objectivos educacionais e
estratégias/actividades, assim como a sua fundamentação. Procurou-se ainda
identificar as barreiras sentidas pelos membros do grupo relativas ao trabalho
em comunidade de prática online.
Como técnicas de recolha de dados recorreu-se a: a) inquérito por
questionário; b) observação directa (mediada pela plataforma Blackboard
academic suite) não participante; c) recolha de documentos. Quanto às
técnicas de análise de dados optou-se por: a) análise estatística descritiva; b)
análise de conteúdo; c) análise documental interna.
Os resultados indicam que no decurso do trabalho desenvolvido na
comunidade de prática online, constituída, os seus membros: a) sentiram
dificuldades de explicitação de objectivos educacionais e de momentos e
formas de avaliação; b) integraram no trabalho desenvolvido indicadores
oriundos da investigação, nomeadamente relativos a trabalho de campo,
resolução de problemas e movimento Ciência, Tecnologia e Sociedade; c)
fundamentaram pouco as práticas desenvolvidas, tendo-se verificado que a
existente remeteu para a adequação ao contexto e incidiu essencialmente
sobre as tarefas planificadas; d) reconheceram como condicionantes à sua
participação barreiras de cariz social, temporal e de pré-requisitos.
ABSTRACT: One of the areas of Science Education research aims at the improvement of
the process of teaching and learning. There appears to be a natural
convergence of interests between teachers and researchers that, nevertheless,
does not always materialize in forms of collaborative work. This gap between
research and teaching practice was identified and has been a reason for the
development of many research projects, among which the project “Investigation
and school Practices in Science Education: dynamic of interaction” stands out,
that “harbors” the present study. The above-mentioned project aims to
contribute towards the articulation between the educational practices and
research in Science Education. An online community of practice was
constituted that aims to promote the professional development of all members
involved.
The central question of this study concerns the implications resulting from the
involvement of teachers and researchers in an online community of practice at
the level of their intended curriculum management.
We opted for a methodology of a predominantly qualitative, descriptive and
exploratory nature, of the single case study type. The case is confined to a
group of teachers and researchers of the above-mentioned project. This study
had two phases. In the first one, we selected the group to analyze, based on
the following criteria: a) the sense of community index (McMillan and Chavis,
1986); b) group work formats; c) the presence of community of practice
indicators (Wenger, 1998). In the second phase, we analyzed the intended
curriculum management carried out by the selected group at the level of
educational objectives and strategies/activities, as well as their grounding. We
also identified the obstacles faced by the members of the group as to the online
community of practice work.
The data gathering techniques/instruments were the following: a)
inquiry/questionnaire; b) direct (mediated by the LMS Blackboard) and non
participant observation; c) collection of documents. As for the data analysis
techniques we elected: a) descriptive statistical analysis; b) content analysis; c)
internal documental analysis.
The results indicate that in the course of the work developed in the online
community of practice, its members: a) found it hard to express the educational
objectives and the moments and forms of evaluation; b) integrated research
indicators in the work developed, namely related to field work, problem solving
and the Science, Technology and Society movement; c) the practices
developed were little substantiated and, when this happened, it pointed to the
adequacy to the context and focused on the planned tasks; d) recognized as
barriers to their participation in the community of practice, obstacles of social,
time and prerequisite skills nature
Comunidades de prática online: contributos para a prática letiva: um estudo de caso no âmbito da educação em ciência envolvendo professores e investigadores
Doutoramento em Didática e FormaçãoAs comunidades de prática (CoP), bem como a investigação-ação, têm vindo a
ser apontadas na literatura como formas de promover o desenvolvimento
profissional de professores, potenciando a melhoria das suas práticas letivas.
Contudo, as evidências empíricas relativas às práticas letivas desenvolvidas
por professores no âmbito dessas configurações sociais são escassas. Neste
estudo procura-se contribuir para colmatar essa lacuna ao analisar uma CoP
online, que envolveu professores de ciências e investigadores em Educação
em Ciência (EC) e se constituiu no âmbito do projeto “Investigação e práticas
lectivas em Educação em Ciência: Dinâmicas de interacção” (IPEC), com
enfoques distintos, a que se alude abaixo.
A investigação realizada envolveu uma metodologia de natureza
predominantemente qualitativa, descritiva, exploratória e do tipo estudo de
caso único, sendo o caso as práticas letivas desenvolvidas pelos membros da
CoP referida e as dinâmicas de interação entre os mesmos. Como técnicas de
recolha de dados, recorreu-se principalmente à observação mediada pela
plataforma online de apoio ao desenvolvimento do projeto (dados estatísticos e
as mensagens registadas automaticamente) e recolha de documentos. Quanto
às técnicas de análise de dados, optou-se principalmente pela análise de
conteúdo e análise documental interna, tendo-se triangulado dados de
diferentes fontes. Com base no Interconnected Model of Teacher Professional
Growth, que Clarke e Hollingsworth propuseram em 2002, e em instrumentos
de análise resultantes da revisão de literatura, adaptados aos enfoques
definidos, a análise da CoP selecionada incidiu sobre: a) os domínios externo
e das práticas de desenvolvimento curricular (DC), ou seja, as suas dinâmicas
de interação durante dois anos letivos; b) o domínio das consequências nas
práticas letivas, no que concerne às estratégias de ensino de ciências
desenvolvidas; c) a evidências do seu carater inovador; e d) aos princípios de
DC operacionalizados através do módulo curricular desenhado, implementado,
avaliado e disseminado pelos membros da CoP.
Os resultados indicam que a) a participação dos membros variou ao longo do
período de interação e que a sua dinâmica se enquadra numa adaptação das
fases de desenvolvimento de CoP proposta por Wenger e colegas em 2002,
com dois ciclos de investigação-ação; b) a CoP desenvolveu estratégias de
ensino diversificadas, pouco exploradas por professores e coerentes com
diversas recomendações da literatura, de forma consistente; c) as práticas
letivas são inovadoras, do tipo challenging, tendo incluído o envolvimento de
professores que lecionavam nas escolas dos professores membros da CoP; e
d) a CoP operacionalizou vários princípios de DC recomendados na literatura,
nomeadamente a flexibilidade e diferenciação. Os resultados empíricos
permitiram ainda validar as dimensões do modelo de Clarke e Hollingsworth,
assim como adaptar à especificidade do caso analisado.Pelo acima referido, embora reconhecendo as limitações do estudo,
nomeadamente relativas às opções metodológicas efetuadas, foi possível
inferir que o trabalho realizado no seio desta CoP online de professores e
investigadores contribuiu para a inovação e melhoria de práticas letivas de EC.
Do estudo resultam ainda instrumentos de análise que se consideram
relevantes, dado poderem vir a ser usados em investigações futuras, assim
como poderem vir a orientar professores de ciências que desejem alinhar as
suas práticas de ensino com recomendações da investigação em EC. Por fim,
são apresentadas recomendações relativamente ao envolvimento de
professores e investigadores em CoP online, no âmbito da EC, assim como
relativamente a possibilidades ao nível de investigações futuras,
nomeadamente a validação dos instrumentos e das recomendações
apresentadas em contextos mais abrangentes e transversais.Communities of practice (CoP), as well as action-research, have been pointed
in the literature as ways of promoting teachers’ professional development,
endorsing the improvement of their teaching practice. However, empirical
evidence regarding the teaching practice developed by teachers in those social
configurations are scarce. This study aims to contribute to address this
shortcoming by analysing an online CoP of science teachers and Science
Education (SE) researchers formed under the project “Investigação e práticas
lectivas em Educação em Ciência: Dinâmicas de interacção” (IPEC), with
different foci, alluded to below.
The research involved a mainly qualitative, descriptive, and exploratory single
case study methodology. It focused on both the teaching practice developed by
the members of the referred CoP, as well as their dynamics of interaction. As
far as data collection techniques, we resorted mainly to observation mediated
by the online platform of support of the development of the project (statistic
data and posts automatically recorded) and documents collection. Regarding
data analysis techniques, we resorted mainly to content analysis and document
analysis. Data from different sources has been triangulated. Based on the
Interconnected Model of Teacher Professional Growth that Clarke and
Hollingsworth proposed in 2002, as well as in analysis instruments that resulted
from the literature review, adapted to the foci of the study, the analysis of the
selected CoP was made on: a) the external domain and domain of practice of
curricular development (CD), in other words, their dynamics of interaction
during two school years; b) the domain of the consequences in the teaching
practice, regarding the developed science teaching strategies; c) evidence of
their innovative nature; and d) the principles of CD operationalized through the
curricular module that the members of the CoP designed, enacted, evaluated
and disseminated.
The results show that a) the members’ participation varied during the
interaction period and their dynamic fits an adaptation of the stages of
development of a CoP proposed by Wenger and colleagues in 2002, with two
cycles of action-research; b) the CoP developed diverse teaching strategies,
usually not explored by teachers, and coherent with commendations in the
literature in a consistent way; c) the teaching practice was innovative, in a
challenging way, and included the involvement of teachers that were teaching
in the schools of the teachers who were members of the CoP; and d) the CoP
operationalized several principles of CD commended in literature, namely
flexibility and differentiation. The empirical results also allowed to validate the
dimensions of the Clarke and Hollingsworth’s model, as well as to adapt to the
specificity of the analysed case.Considering the above, whilst acknowledging the study limitations, namely
regarding the methodological options, it was possible to infer that the work
developed in this online CoP of teachers and researchers contributed to the
innovation and improvement of teaching practices in SE. From this study also
resulted analysis instruments that we consider relevant, as they can be used in
future research, as well as to guide science teachers who wish to align their
teaching practice with commendations from SE literature. Lastly,
commendations are presented, regarding the involvement of teachers and
researchers in online CoP in SE contexts, as well as the possibility of future
research, namely the validation of instruments and of the presented
commendations within broader and transversal contexts
Mobile augmented reality game-based learning: teacher training using the EduPARK app
With the mobile technology widespread, new functionalities are being integrated in devices, namely augmented reality (AR), which can be used to enhance learning. Combining mobile AR learning with game-based approaches supports new forms of instruction in the outdoors and students’ engagement and motivation for learning are enhanced. However, new practices require teacher training. This is the case of the EduPARK workshop that aims to support teachers in the development of innovative outdoor practices, using mobile devices, AR and games. In this exploratory case study, qualitative and quantitative data were collected from five editions of the EduPARK workshop through a mandatory questionnaire and a voluntary reflexive self-account. Results show that teachers value this training for: i) the access to new educational resources, ii) the practices changing support, iii) knowledge update, although not necessarily in what concerns mobile learning, AR and game-based approaches, and iv) learning about cross-subjects approaches to teaching.publishe
Gestão curricular intencional numa comunidade de professores e investigadores
A presente comunicação visa divulgar a gestão curricular intencional (GCI) realizada numa comunidade de prática (CoP) online de professores e investigadores, constituída no âmbito do projecto “Investigação e práticas lectivas em Educação em Ciência: Dinâmicas de interacção” (IPEC). Foi desenvolvido um módulo curricular de trabalho de campo na temática da Sustentabilidade, dirigido a alunos do ensino secundário. A CoP procurou fundamentar científica e didacticamente o módulo desenvolvido, tendo sentido dificuldades na definição dos objectivos educacionais. Foi privilegiado o trabalho de grupo, sendo as estratégias mais frequentes a exposição (pelo docente ou aluno), o debate e o trabalho prático. As docentes envolvidas apontaram impactos e constrangimentos associados ao seu envolvimento na CoP e manifestaram elevada satisfação com o mesmo
Contributions to teaching practice of an online community of practice of teachers and researchers
Communities of practice (CoP) have the potential to promote teachers’ professional
development (PD) and change practices. However, empirical evidence is still scarce. This
study aims to contribute to address this shortcoming by analysing an online CoP. A
qualitative, descriptive, and exploratory single case study was performed. It focused on both
the teaching practice and the CoP’s dynamics of interaction. Data collection included online
platform information (statistic data and posts automatically recorded) and documents. Data
analysis was based on content analysis and was organized accordingly the Interconnected
Model of Teacher Professional Growth that Clarke and Hollingsworth proposed in 2002. The
analysis was made on: (a) the external domain and domain of practice of curricular
development (CD), in other words, their dynamics of interaction; (b) the domain of the
consequences in the teaching practice, regarding the developed science teaching strategies; (c)
evidence of their innovative nature; and (d) the principles of curricular development (CD)
enacted. The results show that (a) the members’ participation varied during the interaction
period and their dynamic fits an adaptation of the stages of development of a CoP proposed
by Wenger et al. in 2002, with two cycles of action-research; (b) the CoP developed diverse
teaching strategies, usually not explored by teachers, and coherent with commendations in the
literature; (c) the teaching practice was innovative, in a challenging way; and (d) the CoP
enacted several principles of CD recommended in literature, namely flexibility and
differentiation. The empirical results also allowed to validate the dimensions of the Clarke and
Hollingsworth’s model, as well as to adapt it to the specificity of the analysed case
Utilização de tecnologias de comunicação online: caso de um projecto envolvendo investigadores e professores
Neste contributo apresenta-se uma síntese da utilização de ferramentas online feita pelos participantes no projecto “Investigação e práticas lectivas em Educação em Ciência: Dinâmicas de interacção” (IPEC), bem como uma reflexão sobre as dificuldades identificadas durante o processo e as evidências de desenvolvimento de competências de comunicação online. O projecto IPEC envolveu trabalho colaborativo entre professores e investigadores, no contexto de Educação em Ciência. As interacções entre os participantes centraram-se na concepção, aplicação e avaliação de módulos curriculares sobre o tema Sustentabilidade e decorreram maioritariamente através de ferramentas de comunicação online disponibilizadas na plataforma Blackboard Academic Suite. Complementarmente foram também exploradas outras ferramentas como o Skype, programas de videoconferência e Googledocs. Ao nível do trabalho com alunos, alguns professores envolvidos no projecto utilizaram blogs, a plataforma Moodle e o Second Life
Moving learning into a smart urban park: students' perceptions of the Augmented Reality EduPARK mobile game
The EduPARK game is developed under a game-based learning methodology. It is designed for outdoor learning settings by employing geocaching principles and mobile Augmented Reality technologies. The game aims to develop users’ authentic and autonomous learning about diverse interdisciplinary themes in a smart urban park. It integrates learning guides for different target groups of basic education. The purpose of this paper is to present the game prototype development, and its first cycle of refinement, as the study followed a design-based research approach. The game evaluation involved 74 students from two school levels (aged 9-10 and 13-14). They explored and evaluated the game. Participant observation and focus groups were conducted. The evaluation allowed identifying positive characteristics of the game, such as immediate feedback and collaborative dynamics. Some questions included in the learning guides were perceived as difficult to understand and also some features came out to be considered for future improvements.publishe
