Abstract The purpose of this study was to examine the mathematical modelling competencies of student mathematics teachers within a learning environment that was based on a holistic approach to instruction. The participants were student mathematics teachers enrolled in undergraduate programmes at two different universities. In one of the university programmes, the participants took a mathematical modelling course that was taught according to a holistic approach, while the participants at the other university followed the standardized undergraduate programme that did not include a mathematical modelling course. The sub-competencies of mathematical modelling of the student mathematics teachers who participated in the mathematical modelling course were examined using an analytic rubric that was designed according to the holistic approach applied within the context of the study. In order to determine whether the observed changes were related to the experiences of mathematical modelling, these results were compared to the sub-competencies of mathematical modelling of the control group. The findings showed that experience within a learning environment based on mathematical modelling, as well as affective factors, supported the development of modelling competencies. On the other hand, it was observed that certain sub-competencies were difficult to develop; while many sub-competencies were enhanced by the modelling experiences, others were adversely affected. Furthermore, a certain group of sub-competencies was found not to be directly linked to modelling experiences.

The aim of the study is to estimate the effect of the Russian academic excellence project (Project 5-100) on the publication activity of the University of Tyumen, measured by the number of articles published in journals indexed in the Web of Science database. The hypothesis of the research is that there is a positive causal relationship between the number of published articles and the University’s participation in Project 5-100. This impact was estimated empirically for the University of Tyumen while the other university participants (31 universities) were taken as a control group. Counterfactual scenarios are used to find the number of articles that the university employees would have published in the absence of Project 5-100. Thus, it is shown that, despite the failure to meet the goal of entering the top 200 of world universities in the ranking for ecology and agricultural biology, the University of Tyumen benefited from its participation in Project 5-100: its number of publications, especially in journals of the first and second quartile, has been growing faster than in the control group of universities.

Until my very inspiring associations with the Mathematics teachers of the University, I should have said that the contribution of the department of Mathematics to the department of English lay in the correction of a child's inaccuracies of speech— the troubling verbs, and the no less troubling pronouns. But four years of delightful professional camaraderie with my friends, the mathematicians, have taught me that this correction of verbal errors, while it is a help for which all English teachers are grateful, is by no means the greatest service which the one department renders to the other. No child handicapped from birth by constant association with illiterate minds, ever learns to speak accurately just because he is required by teachers of all departments to stumble again and again over a recitation until he has straightened out his verbs and purified his pronouns. To a child handicapped by environment, accuracy of speech comes only as the result of an inward desire—a yearning, a craving, a passion, for accuracy, In the development of linguistic power as well as in the development of character, we are saved by desire and not by compulsion; we are saved from within and never from without. The correction of a specific inaccuracy, therefore, is a help, to be sure; but it is neither the only nor yet the greatest service rendered, as many of us in our blindness had once supposed it to be.

Insight Into

Current research areas in the field of mathematical modelling are identified on the basis of specific research and development projects. Modelling cycles are an important theoretical basis for this. The measurement of students modelling competencies as well as that of competencies for teaching mathematical modelling with the help of written tests are important components. The investigation of different mathematical modelling tools, such as the use of technology in larger control group studies, and the evaluation of lecture series in teacher education, are current lines of research in the field of modelling in mathematics education. Overall, selected studies from Germany are used as examples to provide insight into the current research landscape.

The Relationship

The 21st century requires people to make good decisions based on thoughtful and reasoned thinking. It is the task of the university teacher to provide the necessary conditions to develop critical thinking by using strategies that place the student as the basis of teaching work. The objective of the research was to determine the relationship between the level of critical thinking and the level of learning of mathematics of students entering university. The research is based on the quantitative correlational scope approach with transectional, correlational design. The sample was 115 students belonging to two universities, one private and the other public, located in Lima, Peru. For data collection, two tests were administered: one to assess the level of critical thinking, and the other to assess the level of learning in mathematics. The results show that critical thinking and learning of mathematics are significantly correlated. Likewise, each dimension of mathematics learning is significantly correlated with critical thinking. It is concluded that critical thinking favors the learning of mathematics in students entering university. This research serves as an indicator for mathematics teachers to use teaching strategies that develop critical thinking at the university level to obtain better results in learning mathematics. [El siglo XXI requiere de personas que tomen buenas decisiones en base a un pensamiento reflexivo y razonado. Es tarea del docente universitario brindar las condiciones necesarias para desarrollar el pensamiento crítico y utilizar estrategias que sitúen al estudiante como centro de la labor de enseñanza. El objetivo de la investigación fue determinar qué relación existe entre el nivel de pensamiento crítico y el nivel de aprendizaje de la matemática en estudiantes ingresantes a la universidad. La investigación se basa en el enfoque cuantitativo de alcance correlacional y diseño transeccional-correlacional. La muestra fue de 115 estudiantes pertenecientes a dos universidades, una privada y otra pública situadas en Lima, Perú. Para la recolección de datos se administraron dos test: uno para evaluar el nivel de pensamiento crítico, otro para evaluar el nivel de aprendizaje de la matemática. Los resultados evidencian que el pensamiento crítico y aprendizaje de la matemática se correlacionan significativamente. Así mismo, cada dimensión del aprendizaje de la matemática se correlaciona significativamente con el pensamiento crítico. Se concluyó que el pensamiento crítico favorece el aprendizaje de la matemática en estudiantes ingresantes a la universidad. Esta investigación sirve como indicador para que los docentes de matemática en el nivel universitario utilicen estrategias de enseñanza que desarrollen el pensamiento crítico para obtener mejores resultados en el aprendizaje de la matemática].

When interacting on a learning task, which is typical of several academic situations, individuals may experience two different motives: Understanding the problem, or showing their competences. When a conflict (confrontation of divergent propositions) emerges from this interaction, it can be solved either in an epistemic way (focused on the task) or in a relational way (focused on the social comparison of competences). The latter is believed to be detrimental for learning. Moreover, research on cooperative learning shows that when they share identical information, partners are led to compare to each other, and are less encouraged to cooperate than when they share complementary information. An epistemic vs. relational conflict vs. no conflict was provoked in dyads composed by a participant and a confederate, working either on identical or on complementary information (N = 122). Results showed that, if relational and epistemic conflicts both entailed more perceived interactions and divergence than the control group, only relational conflict entailed more perceived comparison activities and a less positive relationship than the control group. Epistemic conflict resulted in a more positive perceived relationship than the control group. As far as performance is concerned, relational conflict led to a worse learning than epistemic conflict, and - after a delay - than the control group. An interaction between the two variables on delayed performance showed that epistemic and relational conflicts were different only when working with complementary information. This study shows the importance of the quality of relationship when sharing information during cooperative learning, a crucial factor to be taken into account when planning educational settings at the university.

The study aimed to assess the number, localization and distribution of interleukin 6 (IL-6) positive cells in healthy pulp, acute and chronic pulpitis. The study group included 48 patients aged between 18-72, treated in University of Medicine and Pharmacy Grigore T. Popa Iasi, Romania. The pulpectomy was performed on 42 patients diagnosed with acute and chronic pulpitis. The other 6 patients, without signs of dental caries or periodontal disease, were submitted to extractions of teeth for orthodontic purposes, with pulpectomy performed before extraction. The pulp samples were examined with optic microscope. The detection and assessment of IL-6 were performed using immunohistochemical technique. Data were statistically analysed using non-parametric tests. According to morphopathological criteria, 42.85% were classified as acute pulpitis and 57.14% as chronic pulpitis. The pulp samples in control group were not associated with IL-6 positive cells. The analysis of all samples with acute and chronic pulpitis identified 73.80% samples with IL-6 and 26.20% associated with the absence of IL-6. The highest frequency of IL-6 positive cells was recorded in rich-cell zone of crown dental pulp. The systemic distribution of IL-6 positive cells was mostly diffused without well-defined orientation. IL-6 release in acute and chronic pulpitis is significantly higher comparing with healthy pulp tissue.

Before And After

Moderate and severe periodontitis represents a challenge in the non-surgical periodontal therapy. Due to the lack of evidence regarding the antimicrobial effectiveness of 940 nm diode laser in periodontal treatment, this study aimed to evaluate the antimicrobial effect of hydrogen peroxide (H2O2) photolysis performed with 940 nm diode laser in the treatment of moderate and severe periodontitis. Twenty-five patients with 100 teeth were selected for this pilot study. The test teeth were randomly assigned to one of the four treatment groups: Group 1: scaling and root planning (SRP) (control group); and the following experimental groups: Group 2: H2O2; Group 3: 940 nm diode laser therapy; Group 4: 940 nm diode laser therapy and H2O2. Clinical examinations, like probing depth (PD), clinical attachment level (CAL) and bleeding on probing (BOP) were performed before and after the treatment. The microbiological evaluation, effectuated before and after the treatment, included nine periodontal bacteria species and investigated by means of real-time PCR assay. The clinical and bacterial differences in the tested groups, was assessed between control group and the other three experimental groups, as well as between the experimental groups. The total bacteria load was reduced for all four studied groups. Group 4 (diode laser + H2O2) showed significant bacterial reduction of the major periodontal bacteria like Pg., Tf., Td., Pi., Pm., Fn (p[0.001) than the other 3 groups (p]0.001). Also the periodontal clinical parameters, like PD, CAL and BOP showed a significant reduction after the photolysis of H2O2 with the 940 nm diode laser (p[0.001). Differences between tested groups showed a significant beneficial results in regard to Group 4.It is suggested that the photoactivation of H2O2 with the 940 nm diode laser can be used successfully in adjunctive to the non-surgical periodontal treatment as a bactericidal tool.
