Changing students’ and teachers’ concepts and constructs of knowledge in RE in Greece

ABSTRACT

Based on a qualitative research (2012–15) this paper is concerned with the identification of concepts and constructs of knowledge in RE. It is based on participative enquiry and educational action-research methodology. Over a three-year period, the researcher, teachers and the students of a High School in one of the most difficult social, economic and pedagogic environments in Greece collaborated and the resulting data were analysed by a team of independent researchers using quantitative and qualitative techniques. Findings point to the consideration of knowledge in education as an experience in which the content (what) of education is as important as the process (how). RE teaches an additional invaluable language with different religious meanings of concepts, which facilitates students’ communication with self and others, and offers an interpretation of the world. Such religious literacy is essentially provided at school in the framework of multi-literacies and is a result of an intersubjective process of the interconnection between thinking, reflection and action on what the curriculum positions on the top of the didactic triangle (content, teacher, student). In that process, to ‘know what I know’ and to provide ‘events with meaning’ based on experiential learning and its principles, is of inestimable value.     

第二语言的语义通达机制的实验研究

采用典型启动效应的实验范式，语义和语音两种不同加工水平的试验任务，通过3个实验探讨了中英双语第二语言的语义通达机制。被试为第二军医大学的学生38名。结果发现：在基于语义的范畴判断任务中，当启动刺激（英）和目标刺激（英）之间存在语义联想关系，得到了显著的启动效应（实验一）；当启动刺激（中）和目标刺激（英）之间存在语义联想关系，即与实验一对等的跨语言语义启动试验，也得到了显著的跨语言启动效应，而且实验一和实验二的启动值之间没有显著的差异（实验二）；当启动刺激（中）的翻译对等词和目标刺激（英）之间存在语音相同或相近关系时，采用基于语音的词汇判断任务，也得到了显著的跨语言启动效应。这一结果表明，对于中国大学生程度的中英双语者来说，他们第二语言的词汇表征既直接通达语义概念表征，又可以借助第一语言的词汇表征为中介再通达语义概念表征，与Kroll等提出的模型一致。     

Motivating Constraints of a Pedagogy-Embedded Computer Algebra System

The constraints of a computer algebra system (CAS) generally induce limitations on its usage. Via the pedagogical features implemented in such a system, “motivating constraints” can appear, encouraging advanced theoretical learning, providing a broader mathematical knowledge and more profound mathematical understanding. We discuss this issue, together with two examples from Calculus, which show an important feature of an instrumentation process.     

Refutational text and multiple external representations as a method to remediate the misinterpretation of box plots

The ability to interpret graphs is highly important in modern society, but has proven to be a challenge for many people. In this paper, two teaching methods were used to remediate one specific misinterpretation: the area misinterpretation of box plots. First, we used refutational text to explicitly state and invalidate the area misinterpretation of box plots. Second, we used multiple external representations (MERs): Histograms were used as an overlay on box plots in order to give students a better insight in the way box plots represent data distributions. Third, we combined refutational text and MERs. We found that refutational text was successful in improving students’ interpretation of box plots, but that the use of MERs did not improve students’ interpretation of box plots. The addition of MERs also did not increase the effect of refutational text.     

Effect of a Problem Based Simulation on the Conceptual Understanding of Undergraduate Science Education Students

A study of the effect of science teaching with a multimedia simulation on water quality, the “River of Life,” on the science conceptual understanding of students (N = 83) in an undergraduate science education (K-9) course is reported. Teaching reality-based meaningful science is strongly recommended by the National Science Education Standards (National Research Council, 1996). Water quality provides an information-rich context for relating classroom science to real-world situations impacting the environment, and will help to improve student understanding of science (Kumar, 2005a; Kumar and Chubin, 2000). The topics addressed were classes of organisms that form river ecosystem, dissolved oxygen, macroinvertebrates, composition of air, and graph reading skills. Paired t-test of pre- and post-tests, and pre- and delayed post-tests showed significant (p < 0.05) gains. The simulation had a significant effect on the conceptual understanding of students enrolled in a K-9 science education course for prospective teachers in the following areas: composition of air, macroinvertebrates, dissolved oxygen, classes of organisms that form a river ecosystem, and graph reading skills. The gain was more in the former four areas than the latter one. A paired t-test of pre- and delayed post-tests showed significant (p < 0.05) gains in the water quality and near transfer subsets than the dissolved oxygen subset. Additionally students were able to transfer knowledge acquired from the multimedia simulation on more than one concept into teachable stand-alone lesson plans.     

Scoring mode and age-related effects on youth soccer teams’ defensive performance during small-sided games

ABSTRACT

This study aimed to examine the scoring mode (line goal, double goal or central goal) and age-related effects on the defensive performance of youth soccer players during 4v4 small-sided games (SSGs). Altogether, 16 male players from 2 age groups (U13, n = 8, mean age: 12.61 ± 0.65 years; U15, n = 8, 14.86 ± 0.47 years) were selected as participants. In six independent sessions, participants performed the three SSGs each during 10-min periods. Teams’ defensive performance was analysed at every instant ball possession was regained through the variables: ball-recovery type, ball-recovery sector, configuration of play and defence state. Multinomial logistic regression analysis used in this study revealed the following significant main effects of scoring mode and age: (1) line goal (vs. central goal) increased the odds of regaining possession through tackle and in the defensive midfield sector, and decreased the odds of successful interceptions; (2) double goal (vs. central goal) decreased the odds of regaining possession through turnover won and with elongated playing shapes; (3) the probability of regaining possession through interception significantly decreased with age. Moreover, as youth players move forward in age groups, teams tend to structurally evolve from elongated playing shapes to flattened shapes and, at a behavioural level, from defending in depth to more risky flattened configurations. Overall, by manipulating the scoring mode in SSGs, coaches can promote functional and coadaptive behaviours between teams not only in terms of configurations of play, but also on the pitch locations that teams explore to regain possession.     

Empowerment and women in adventure tourism: a negotiated journey

Women’s participation in adventure tourism is growing, yet few studies have explored this group of tourists. This conceptual paper seeks to extend our understanding of female adventure tourists by examining the empowering journey women can take through constraint negotiation to enjoy the benefits of adventure tourism. Using content analysis to review the literature on women’s adventure experiences in tourism and recreation settings reveals prominent themes that have been consolidated to propose constraint, negotiation and benefit categories. A conceptual model is presented that illustrates the opportunities for women’s empowerment within these categories and examines the interrelationships and interdependency between them. The model shows that constraints, negotiations and benefits can be experienced simultaneously, at different points in a woman’s adventure tourism journey and used as a vehicle for empowerment. Women will also re-evaluate these categories before, during and after their adventure tourism experience. Therefore, the categories are not fixed and evolve each time a woman participates in adventure tourism throughout her life. Suggestions are made for further study in this under-researched area.

Performance environment and nested task constraints influence long jump approach run: a preliminary study

The purpose of the study was to investigate possible changes at step pattern and technical performance of the long jump approach run in seven young long jumpers by modifying the performance environment (long jump runway versus track lane) and the nested actions (run-through with take-off versus complete long jump). Our findings suggest that the step pattern and technical aspects of the approach run are affected by environmental context and nested task constraints. In terms of environmental context, it appears that practising the training routine of run-through followed by take-off on the long jump runway allows athletes to simulate competition conditions in terms of step regulation and technical efficacy. The task of run-through followed by take-off on the track lane failed to initiate visual perception, step regulation and technical efficiency at the steps preceding the instant of take-off. In terms of nested task constraints, when run-ups were followed by jump for distance instead of only a take-off, a higher level of consistency was achieved and step regulation was based on perception–action coupling. Practising long jump run-up accuracy at a setting not containing the informational elements of the performance environment fails to develop the key elements of the skill.     

Informational constraints on interceptive actions of elite football goalkeepers in 1v1 dyads during competitive performance

The aim of this study was to examine whether perceptual variables can provide informational constraints for the goalkeepers to intercept the ball successfully in 1v1 dyads. Video images of 42 actions (1v1 in direct shots) were selected randomly from different matches and divided into conceded goals (n = 20) and saved actions (n = 22) to investigate interceptive actions of 20 goalkeepers in the English Premier League in season 2013–2014. Time to Contact (TTC) of the closing distance gap between shooter and goalkeeper was obtained by digitising actions in the 18-yard penalty box. Statistical analyses revealed that, in sequences of play resulting in an intercepted shot at goal, goalkeepers closed down outfield players in the X axis, whereas when a goal was conceded, there was a significantly delayed movement by goalkeepers toward the shooters in this plane. The results of canonical correlations showed that a decreasing distance between a shooter and goalkeeper, and accompanied reduction in relative interpersonal velocity followed a temporal pattern. Findings of this study showed how perception of key informational constraints on dyadic system relations, such as TTC, interpersonal distance and relative velocity, constrain elite goalkeepers’ interceptive actions, playing an important role in successful performance.
