For many students, mathematics, traditionally thought to be difficult and dull, is often considered inaccessible, generating a negative attitude towards it. In order to encourage a positive attitude towards mathematics, we propose class practices that, through research activities, will lead the students to experiment a similar path to the one that has given, as a final product, a structured theory, so as to enhance their self-efficacy, give a correct vision of the discipline and stimulate positive emotions. This can be realized, for example, as a “laboratory activity” in which the students compare ideas, intuitions, arguments, and work together to obtain results, using their critical capabilities in a collaborative learning activity. A team of university professors and high school teachers has developed a laboratory activity that focuses on some properties of quadrilaterals. The activity has at any rate been experimented in different first biennium classes of some high schools and has obtained very good results.

Syftet med denna undersökning har varit att studera huruvida individuella målsättningaranvänds inom elitfotboll. Dessutom undersöktes vilka målsättningsstrategier som föredrassamt vilka av dem som uppfattas som mest effektiva. Vidare studerades hur användningen avolika målsättningsstrategier är relaterat till elitfotbollspelares upplevda kompetens ochmotivation. . Även skillnader mellan ordinarie och icke ordinarie spelare samt juniorer ochseniorer studerades. Slutligen undersöktes även interaktionen mellan målsättningsarbetet,motivation och upplevd kompetens. Totalt deltod 101 fotbollsspelare i studien. Metoden somanvändes var kvantitiv och bestod av enkäterna GSSQ, TEOSQ samt Harterskompetensfrågeformulär (1980). Resultaten visade att resultatmål var som den mestföredragna målsättningen. Vidare var inre motivationsinriktning vanligare än yttre. Resultatenvisade även att målsättningars upplevda effektivite samt spelarnas motivation var lägst hosicke ordinarie juniorer. Interaktionseffekterna visade även att icke ordinarie juniorer uppleverlägre nivå av upplevd kompetens. Resultaten diskuteras i förhållande till uppsatsens teoretiskaramverk. Nyckelord: Elitfotbollsspelare, motivation, målsättning, upplevd kompetens / The purpose of this study was to examine if individual goal setting are being used byprofessional soccer players, what kind of goal setting is preferred and which of those areperceived as most effective. How the use of goal settings are related to professional soccerplayers and elite junior players perceived competence and motivation is also being examined.Also difference between regular, non-regular, juniors and senior players was studied. Finally,the interaction between the use of goal settings, motivation and perceived competence wereexamined. 101 soccer players participated in the study. A quantitative method with thequestionnaires GSSQ, TEOSQ and Harter’s competence questionnaire was used. The resultsshowed that performance goals were the most preferred and that task orientation was morecommon than ego. Perceived effectiveness of goal setting and the player’s motivation waslowest among non-regular juniors. Interaction results also showed that non-regular juniorsshowed low perceived competence. The results are discussed in relation to the essay’stheoretical framework. Keywords: Goal settings, motivation, perceived competence, professional/elite soccer players.

Background: Unemployment may impair mental and physical health. The influencing factors causing such negative effects are relevant from an individual and public health perspective. The personality as one possible influencing factor was discussed. This study investigated the prevalence of the type-D personality in an unemployed population and its connections to socio-demographic, psychological and heart rate variability (HRV) parameters. Methods: A questionnaire set including socio-demographics, type-D scale (DS14), Complaint list (BL), Beck-Depression-Inventory II (BDI-II) and the General Self-Efficacy Scale (GSE) was handed out to 203 unemployed individuals [126 females, mean age ± SD: 42.36 ± 11.08]. For HRV assessment (RMSSD), a subsample of 83 participants [50 females, median age ± IQR: 47.00 ± 17.00] passed the “stress-tests” (timed breathing, d2-attention-stress-test, math test) while heart frequency (HF) was acquired via the Stressball software (BioSign GmbH, Ottenhofen, Germany). Results: 53% of the unemployed had a type-D personality. Compared to non-type-D individuals, type-D individuals had rarely children and by trend a lower educational level; they showed significantly higher scores in the BDI-II and lower scores in the GSE and BL. No differences were observed in mean HF or RMSSD during all the stress-tests. Conclusion: The HRV of individuals with a type-D personality is no worse than that of individuals without a type-D personality. Type-D personality was significantly associated with negative health effects regarding depressiveness, self-efficacy and physical complaints. Our main findings implicate that the DS14 could serve as a short and reliable screening instrument to select concerned unemployed individuals who might be at risk for negative health effects for adequate intervention.

Objectives The primary objective of this study was to investigate the effect of the video-based smartphone app ‘VIDEA bewegt’ over eight programme weeks on physical activity in German adults. - Design The study used a single-arm observational design, assessing the app’s effectiveness under real-life conditions. Data were collected from July 2019 to July 2020. - Setting The app is enabling users to access video-based educational content via their smartphone. A clinical visit or in-person contact was not required. Participants All individuals registered in the freely available app were invited to take part in the study. - Interventions The app aims to increase physical activity in everyday life. It combines educative videos on lifestyle-related benefits and instructional videos of strength and endurance exercises to do at home with motivational components like goal setting, documentation of progress and personalised messages. - Primary and secondary outcome measures Primary outcomes were physical activity based one MET minutes per week (metabolic equivalent) and step numbers. Secondary outcomes included physical self-efficacy (motivational, maintenance, recovery self-efficacy), health-related quality of life: Mental Health Component Summary score and Physical Health Component Summary score. - Results Of 97 people included in the data analysis, 55 successfully completed the programme and all questionnaires. Significant increases over eight programme weeks (between T0 and T2) were observed in physical activity based on MET minutes per week, health-related quality of life, and recovery self-efficacy. Time spent sitting and body mass index significantly decreased for those completing the programme. Conclusions Although significant benefits of physical activity were observed following a complete-case analysis, results should be dealt with caution. Studies with a larger and less heterogeneous sample and robust study designs able to measure causal effects would be desirable. Trial registration number DRKS00017392.
