Prove Invalsi: osservare gli studenti nella scelta delle strategie risolutive.

Questa tesi ha permesso di osservare e analizzare le strategie risolutive che gli studenti italiani utilizzano quando si cimentano nello svolgimento delle prove di matematica nazionali INVALSI (Sistema Nazionale per la Valutazione del Sistema dell'Istruzione). L'osservazione è stata svolta durante le ore di tirocinio curriculare effettuate nell'anno accademico 2014/2015 presso il liceo scientifico e delle scienze umane "Albert Bruce Sabin" di Bologna. L'interesse per l'esperimento è nato dalla constatazione dei risultati deludenti degli studenti italiani nelle prove di matematica rispetto all'andamento internazionale. Pertanto,in collaborazione con il prof Giorgio Bolondi, relatore dell'elaborato, e della prof.ssa Valeria Vesi insegnante di matematica delle classi prime seguite durante il tirocinio, è stato realizzato un test di domande estrapolate dalle prove INVALSI svolte negli anni precedenti, sottoposto a un campione di 12 studenti (14-15 anni) frequentanti le classi 1M, 1O e 1R.Il lavoro d'indagine è stato realizzato in due diverse fasi: soluzione del test e intervista-colloquio registrata. Le registrazioni, apparse fin da subito molto interessanti, rivelano importanti informazioni che permettono di evidenziare le diverse difficoltà che i nostri studenti incontrano nel risolvere le prove di matematica. Per meglio interpretare i loro comportamenti durante la messa in atto dei processi risolutivi è stato svolto uno studio e una ricerca riguardanti gli studi e le teorie che interessano il problem-solving, oltre a fornire una panoramica sulle ricerche nel campo della valutazione.

Didattica della Ricerca Operativa nelle scuole superiori

La Ricerca Operativa è considerata una disciplina universitaria il cui insegnamento è previsto nei corsi di laurea di Ingegneria, Matematica e Informatica. Da qualche anno si è verificata una tendenza ad anticipare l'insegnamento della Ricerca Operativa ad un grado scolastico inferiore. In Gran Bretagna e negli Stati Uniti sono presenti organizzazioni molto attive nell'ambito della sua divulgazione e sono nati progetti importanti a livello didattico: corsi di formazione per i docenti, condivisione in rete di materiali e report delle esperienze effettuate. A partire dal 2012 anche nelle indagini internazionali OCSE-PISA si sono aggiunte due aree i cui obiettivi e contenuti si avvicinano alla Ricerca Operativa: financial literacy e problem solving. In Italia, dopo la riforma governativa Gelmini del 2008, sono presenti elementi di Ricerca Operativa solo nei programmi di matematica del quinto anno degli istituti tecnici commerciali e industriali. Tuttavia la Ricerca Operativa può svolgere un ruolo fondamentale nella formazione scientifica, innanzitutto per il suo ruolo di "ponte" tra la matematica e l'informatica, poi per l'importanza dello sviluppo della modellizzazione e per l'interdisciplinarietà della materia e lo stretto contatto con il mondo del lavoro. Inoltre, le esperienze documentate di didattica della Ricerca Operativa hanno potuto verificare l'importante ruolo motivazionale che possiede nei confronti degli studenti meno amanti della matematica. In questo lavoro di tesi si è interrogata la fattibilità di un percorso di Ricerca Operativa per una classe seconda liceo scientifico (anno in cui vengono svolte le indagini internazionali). Viene poi presentata la costruzione di una lezione di Programmazione Lineare che prevede una prima fase di modellizzazione del problema e una seconda fase di soluzione tramite il solutore di excel in laboratorio.

App Ibrida per l’apprendimento della matematica attraverso esercizi di logica

Nell’ambito di questo lavoro di tesi è stata progettata e realizzata un'applicazione di edutainment, pensata per essere fruita attraverso dispositivi mobili, da parte di studenti delle scuole medie, con l’obiettivo di esercitare e migliorare le capacità logiche e di problem solving. La tesi descrive il contesto educativo e scolastico in relazione alla presenza delle tecnologie dell'informazione e della comunicazione, ed infine mostra come una componente di intrattenimento possa essere utile nei processi di apprendimento. Lo sviluppo dell’applicazione è basato sulla progettazione di applicazioni ibride, usando come framework di sviluppo Apache Cordova, quindi attraverso tecnologie web-based, con un’architettura client-server, in cui la parte client gestisce l’interfaccia grafica e le interazioni logiche mentre la parte server viene sfruttata esclusivamente come contenitore di informazioni.

Effectiveness of integrated psychological therapy (IPT) for schizophrenia patients: a research update

Standardized recovery criteria go beyond symptom remission and put special emphasis on personal and social functioning in residence, work, and leisure. Against this background, evidence-based integrated approaches combining cognitive remediation with social skills therapy show promise for improving functional recovery of schizophrenia patients. Over the past 30 years, research groups in 12 countries have evaluated integrated psychological therapy (IPT) in 36 independent studies. IPT is a group therapy program for schizophrenia patients. It combines neurocognitive and social cognitive interventions with social skills and problem-solving approaches. The aim of the present study was to update and integrate the growing amount of research data on the effectiveness of IPT. We quantitatively reviewed the results of these 36 studies, including 1601 schizophrenia patients, by means of a meta-analytic procedure. Patients undergoing IPT showed significantly greater improvement in all outcome variables (neurocognition, social cognition, psychosocial functioning, and negative symptoms) than those in the control groups (placebo-attention conditions and standard care). IPT patients maintained their mean positive effects during an average follow-up period of 8.1 months. They showed better effects on distal outcome measures when all 5 subprograms were integrated. This analysis summarizes the broad empirical evidence indicating that IPT is an effective rehabilitation approach for schizophrenia patients and is robust across a wide range of sample characteristics as well as treatment conditions. Moreover, the cognitive and social subprograms of IPT may work in a synergistic manner, thereby enhancing the transfer of therapy effects over time and improving functional recovery.

Coping With a Family Member's Death: Parenting, Religiosity, and Parent-Child Communication

The present study had three major aims. First, this study was a basic descriptive exploration of the frequency and nature of parent-child communication about death. Second, this study conducted a quantitative analysis to identify predictors of communication and bereaved children¿s emotional and behavioral problems. Third, this study was also a qualitative analysis of parents¿ descriptions of how religious views shape conversations about death and how conversations are beneficial. Based on prior research, it was predicted that positive child outcomes would be associated with parental warmth, religiosity, adaptive coping, positive religious coping, and frequent parent-child communication about death. Conversely, it was predicted that negative child outcomes would be associated with parental psychological control, maladaptive coping, negative religious coping, and less frequent parent-child communication about death. Additionally, it was hypothesized that parents¿ religious and spiritual views would shape parent-child communication about death, and parents would describe numerous benefits of discussing death with children. Parents completed a series of survey measures assessing their religiosity, coping strategies, parent-child communication about death, and their children¿s emotional and behavioral symptoms. Almost 80% of parent-child dyads discussed death at least once a week, and children initiated approximately half of these conversations. Parent-child communication about death was predicted by parents¿ warmth toward and acceptance of their children and inversely predicted by children¿s hyperactivity and social problem solving. Higher levels of children¿s social problem solving could predict lower frequency of parent-child communication about death if children were holding frequent, meaningful, and comforting conversations with friends and other adults. Higher levels of parents¿ psychological control predicted more emotional and behavioral problems in the child. Parents¿ adaptive coping had significant relationships with all of the dimensions of parent-child communication about death. Qualitative analyses revealed that parents perceived their religious beliefs as shaping conversations about death and grief as an individualized journey. A majority of parents described the emotional, social, and intellectual benefits of holding parent-child conversations about death. This study contributes to the literature by further describing parent-child communication about death, identifying its predictors, and investigating parents¿ religiosity and coping strategies in relation to child well-being. Overall, this study revealed the importance of assessing global parenting characteristics (i.e., warmth/acceptance and psychological control) when examining parent-child relationships and communication about death. Furthermore, this unique study illustrates the value of qualitative data when examining parent-child communication about death and religiosity.

Changes in Psychological Characteristics of Working Adults in Different Stages of Economic Transition in Lithuania

Global economic changes have psychological consequences and Mr. Lepeska set out to assess these changes in working adults in Lithuania between 1993 and 1997. He surveyed two groups of working adults, with a total of 200 people, randomly selected and representing different organisations and professions. In both groups around 30% of participants were managers, with the remainder working in non-managerial positions. The participants were surveyed twice, once in 1993 and the second time in 1997,using various psychodiagnostic tools to measure their psychological characteristics. The results showed that strategies for coping with stress have changed, with problem solving strategies being used more often, and avoidance behaviour or seeking social support less. Men tended to have rejected these strategy more radically than women. Attitudes towards work had become more positive, with managers' attitudes having changed more significantly than those of employees from lower levels of organisations. Younger people were more positive towards work-related changes, while situational anxiety tended to increase with age, although overall it remained low. Mr. Lepeska found that while there were some indications of an increasing individualist in relation to peers, the traditional collective orientation of Lithuanian adults had if anything increased. People have become more accepting of an unequal distribution of power, making it difficult to increase the participation of subordinates in decision making. He also noted a tendency for Lithuanians to see their organisations as traditional families, expecting them to take care of them physically and economically in return for loyalty. The strong feminine orientation with its stress on interpersonal relations and overall quality of life has also strengthened, but the ability of Lithuanians to take initiative and control their environment was relatively low. Mr. Lepeska concludes that organisations should seek to recruit people who are able to adjust more easily to changes and consider measuring dominance, individualism, and attitudes to work-related change and situational anxiety in the process of professional selection. There should also be more emphasis on team building and on training managers to maintain closer relationships with their subordinates so as to increase the latter's participation in decision making. Good interpersonal relations can be a strong work motivator, as may be special attention to the security needs of older employees.

Management Challenges in Nurturing a Safe Work Environment

As engineers, we are trained to use logical, rational problem solving to insure our mines operate at maximum efficiency. We tend to use the same technical approach to design safety into all mining systems. This works well for machines, but not so much for the human component. Recent insights in the field of behavioral economics provide useful ideas for addressing the fact that we are driven by emotions more often than by rational thought. Understanding the nonrational aspect of human behavior is an important piece of any safety system design.

The Impact of Western Social Workers in Romania - a Fine Line between Empowerment and Disempowerment

Ideally the social work profession promotes social change, problem solving in human relationships and the empowerment and liberation of people to enhance their well-being (IFSW 2004). The social work practice, however, often proves to be different. Social workers are always in the danger to make decisions for their clients or define problems according to their own interpretation and world view. In quite a number of cases, the consequence of such a social work practice is that the clients feel disempowered rather than empowered. This dilemma is multiplying when western social workers get involved in developing countries. The potential that intervention, with the intention to empower and liberate the people, turns into disempowerment is tremendously higher because of the differences in tradition, culture and society, on the one side and the power imbalance between the ‘West’ and the ‘Rest’ on the other side. Especially in developing countries, where the vast majority of people live in poverty, many Western social workers come with a lot of sympathy and the idea to help the poor and to change the world. An example is Romania. After the collapse of communism in 1989, Romania was an economically, politically and socially devastated country. The pictures of the orphanages shocked the western world. As a result many Non-Governmental Organisations (NGOs), churches and individuals were bringing humanitarian goods to Romania in order to alleviate the misery of the Romanian people and especially the children. Since then, important changes in all areas of life have occurred, mostly with foreign financial aid and support. At the political level, democratic institutions were established, a liberal market economy was launched and laws were adapted to western standards regarding the accession into the European Union and the NATO. The western world has left its marks also at the grassroots level in form of NGOs or social service agencies established through western grants and individuals. Above and beyond, the presence of western goods and investment in Romania is omnipresent. This reflects a newly-gained freedom and prosperity - Romania profits certainly from these changes. But this is only one side of the medal, as the effect of westernisation contradicts with the Romanian reality and overruns many deep-rooted traditions, thus the majority of people. Moreover, only a small percentage of the population has access to this western world. Western concepts, procedures or interpretations are often highly differing from the Romanian tradition, history and culture. Nevertheless, western ideas seem to dominate the transition in many areas of daily life in Romania. A closer look reveals that many changes take place due to pressure of western governments and are conditioned to financial support. The dialectic relationship between the need for foreign aid and the implementation becomes very obvious in Romania and often leads, despite the substantial benefits, to unpredictable and rather negative side-effects, at a political, social, cultural, ecological and/or economic level. This reality is a huge dilemma for all those involved, as there is a fine line between empowering and disempowering action. It is beyond the scope of this journal to discuss the dilemma posed by Western involvement at all levels; therefore this article focuses on the impact of Western social workers in Romania. The first part consists of a short introduction to social work in Romania, followed by the discussion about the dilemma posed by the structure of project of international social work and the organisation of private social service agencies. Thirdly the experiences of Romanian staff with Western social workers are presented and then discussed with regard to turning disempowering tendencies of Western social workers into empowerment.

E-Learning Systems, Environments and Approaches

The volume consists of twenty-five chapters selected from among peer-reviewed papers presented at the CELDA (Cognition and Exploratory Learning in the Digital Age) 2013 Conference held in Fort Worth, Texas, USA, in October 2013 and also from world class scholars in e-learning systems, environments and approaches. The following sub-topics are included: Exploratory Learning Technologies (Part I), e-Learning social web design (Part II), Learner communities through e-Learning implementations (Part III), Collaborative and student-centered e-Learning design (Part IV). E-Learning has been, since its initial stages, a synonym for flexibility. While this dynamic nature has mainly been associated with time and space it is safe to argue that currently it embraces other aspects such as the learners’ profile, the scope of subjects that can be taught electronically and the technology it employs. New technologies also widen the range of activities and skills developed in e-Learning. Electronic learning environments have evolved past the exclusive delivery of knowledge. Technology has endowed e-Learning with the possibility of remotely fomenting problem solving skills, critical thinking and team work, by investing in information exchange, collaboration, personalisation and community building.

Comparative efficacy of seven psychotherapeutic interventions for patients with depression: a network meta-analysis

BACKGROUND Previous meta-analyses comparing the efficacy of psychotherapeutic interventions for depression were clouded by a limited number of within-study treatment comparisons. This study used network meta-analysis, a novel methodological approach that integrates direct and indirect evidence from randomised controlled studies, to re-examine the comparative efficacy of seven psychotherapeutic interventions for adult depression. METHODS AND FINDINGS We conducted systematic literature searches in PubMed, PsycINFO, and Embase up to November 2012, and identified additional studies through earlier meta-analyses and the references of included studies. We identified 198 studies, including 15,118 adult patients with depression, and coded moderator variables. Each of the seven psychotherapeutic interventions was superior to a waitlist control condition with moderate to large effects (range d = -0.62 to d = -0.92). Relative effects of different psychotherapeutic interventions on depressive symptoms were absent to small (range d = 0.01 to d = -0.30). Interpersonal therapy was significantly more effective than supportive therapy (d = -0.30, 95% credibility interval [CrI] [-0.54 to -0.05]). Moderator analysis showed that patient characteristics had no influence on treatment effects, but identified aspects of study quality and sample size as effect modifiers. Smaller effects were found in studies of at least moderate (Δd = 0.29 [-0.01 to 0.58]; p = 0.063) and large size (Δd = 0.33 [0.08 to 0.61]; p = 0.012) and those that had adequate outcome assessment (Δd = 0.38 [-0.06 to 0.87]; p = 0.100). Stepwise restriction of analyses by sample size showed robust effects for cognitive-behavioural therapy, interpersonal therapy, and problem-solving therapy (all d>0.46) compared to waitlist. Empirical evidence from large studies was unavailable or limited for other psychotherapeutic interventions. CONCLUSIONS Overall our results are consistent with the notion that different psychotherapeutic interventions for depression have comparable benefits. However, the robustness of the evidence varies considerably between different psychotherapeutic treatments.

European veterinary public health specialization: post-graduate training and expectations of potential employers

Residents of the European College of Veterinary Public Health (ECVPH) carried out a survey to explore the expectations and needs of potential employers of ECVPH diplomates and to assess the extent to which the ECVPH post-graduate training program meets those requirements. An online questionnaire was sent to 707 individuals working for universities, government organizations, and private companies active in the field of public health in 16 countries. Details on the structure and activities of the participants' organizations, their current knowledge of the ECVPH, and potential interest in employing veterinary public health (VPH) experts or hosting internships were collected. Participants were requested to rate 22 relevant competencies according to their importance for VPH professionals exiting the ECVPH training. A total of 138 completed questionnaires were included in the analysis. While generic skills such as "problem solving" and "broad horizon and inter-/multidisciplinary thinking" were consistently given high grades by all participants, the importance ascribed to more specialized skills was less homogeneous. The current ECVPH training more closely complies with the profile sought in academia, which may partly explain the lower employment rate of residents and diplomates within government and industry sectors. The study revealed a lack of awareness of the ECVPH among public health institutions and demonstrated the need for greater promotion of this veterinary specialization within Europe, both in terms of its training capacity and the professional skill-set of its diplomates. This study provides input for a critical revision of the ECVPH curriculum and the design of post-graduate training programs in VPH.

Ein neues psychoendokrin-validiertes Verfahren zur Erfassung von Stressbewältigungsfertigkeiten (ISBF)

Background: We previously found good psychometric properties of the Inventory for assessment of stress management skills (German translation: Inventar zur Erfassung von Stressbewältigungsfertigkeiten), ISBF, a short questionnaire for combined assessment of different perceived stress management skills in the general population. Here, we investigate whether stress management skills as measured by ISBF relate to cortisol stress reactivity in two independent studies, a laboratory study (study 1) and a field study (study 2). Methods: 35 healthy non-smoking and medication-free men in study 1 (age mean±SEM:38.0±1.6) and 35 male and female employees in study 2 (age mean±SEM:32.9±1.2) underwent an acute standardized psychosocial stress task combining public speaking and mental arithmetic in front of an audience. We assessed stress management skills (ISBF) and measured salivary cortisol before and after stress and several times up to 60 min (study 2) and 120 min (study 1) thereafter. Potential confounders were controlled. Results:. General linear models controlling for potential confounders revealed that in both studies, higher stress management skills (ISBF total score) were independently associated with lower cortisol levels before and after stress (main effects ISBF: p’s<.055) and lower cortisol stress reactivity (interaction ISBF-by-stress: p’s<.029). Post-hoc-testing of ISBF subscales suggest lower cortisol stress reactivity with higher “relaxation abilities” (both studies) and higher scores in the scale “cognitive strategies and problem solving” (study 2). Conclusions: Our findings suggest blunted increases in cortisol following stress with increasing stress management skills as measured by ISBF. This suggests that the ISBF not only relates to subjective psychological but also objective physiological stress indicators which may further underscore the validity of the questionnaire.

Using 'Generic Abilities' to Foster Professionalism in a Post-Professional Program

Introduction To be successful in a profession, persons must have mastery of professional affective behaviors in addition to that profession’s core knowledge base. Health care delivery is more than just developing a good plan of care. The effective health care provider also will have good interpersonal and communication skills, have a commitment to learning, act professionally and responsibly, and have abilities in problem solving and critical thinking. But, these behaviors and characteristics are not taught directly in a professional program. This presentation will demonstrate how these ‘generic abilities’ have been incorporated in a post-professional program and how they can be used in other professional health care, professional development, and leadership programs.

Cognitive Interventions with Children with Special Needs - Transfer effects and multidisciplinary perspectives

Our last study with regularly developed children demonstrated a positive effect of working memory training on cognitive abilities. Building upon these findings, the aim of this multidisciplinary study is to investigate the effects of training of core functions with children who are suffering from different learning disabilities, like AD/HD, developmental dyslexia or specific language impairment. In addition to working memory training (BrainTwister), we apply a perceptual training, which concentrates on auditory-visual matching (Audilex), as well as an implicit concept learning task. We expect differential improvements of mental capacities, specifically of executive functions (working memory, attention, auditory and visual processing), scholastic abilities (language and mathematical skills), as well as of problem solving. With that, we hope to find further directions regarding helpful and individually adapted interventions in educational settings. Interested parties are invited to discuss and comment the design, the research question, and the possibilities in recruiting the subjects.

Beyond questionnaires – Exploring adult education teachers' mathematical beliefs with pictures and interviews

Because of the impact that mathematical beliefs have on an individual’s behaviour, they are generally well researched. However, little mathematical belief research has taken place in the field of adult education. This paper presents preliminary results from a study conducted in this field in Switzerland. It is based on Ernest’s (1989) description of mathematics as an instrumental, Platonist or problem solving construct. The analysis uses pictures drawn by the participants and interviews conducted with them as data. Using a categorising scheme developed by Rolka and Halverscheid (2011), the author argues that adults’ mathematical beliefs are complex and especially personal aspects are difficult to capture with said scheme. Particularly the analysis of visual data requires a more refined method of analysis.
