Students' perceptions of fairness in peer assessment: evidence from a problem-based learning course

This paper describes the experience of peer assessment in a problem-based learning course in a Portuguese university, and presents the results of a survey of 120 students who attended the course over seven semesters. Cluster analysis revealed that students group into two distinct clusters with significantly different experiences of peer assessment. Although the larger cluster (70%) expressed a positive experience, the other group perceived peer assessment results and final marks to be unfair, and reported incidents of friendship-marking and conflict arising from peer assessment. Results show that perceptions of fairness (both regarding peer assessment and final marks) are very much associated with those problems. We reflect on these findings to explore implications for practice as well as future research.     

The Hybrid Construction of Sexuality in Mexico and its Impact on Sex Education

As is now widely established, sexuality is a historically and culturally specific social construction. In Mexico, such construction has been dominated by different institutions and discourses at different times. From pre-Hispanic times to today, this article traces the ideas that main institutions, like the Catholic Church, have ingrained in Mexican sexual culture and shows how they have changed over time. At present, sexuality has become a contested arena?like never before?in which very diverse discourses contend for hegemony. Formal sex education has not been alien to this debate, in which religion, medicine, gender equity discourses and ethics seem to have a differential input in curricula and textbooks. This article discusses the expression of this tension in formal sex education in Mexico.     

Latin American immigrant women and intergenerational sex education

People of Latin American descent make up the largest and fastest-growing minority group in the USA. Rates of pregnancy, childbirth, and sexually transmitted infections among people of Latin American descent are higher than among other ethnic groups. This paper builds on research that suggests that among families of Latin American descent, mothers have a particularly strong influence on the sexual attitudes and behaviours of their children, yet that parents of Latin American descent communicate less with their children about sex than parents of other ethnic groups. It examines the messages about sex women received as children in their countries of origin, and how these messages and their views of the USA influence the sexual education women provide for their children. On the basis of data from focus groups, we suggest that, in spite of the persistence of sexual silence, some women's self-reflective analyses of their own sexual education as well as their views of the USA as a sexually more open society contribute to their views of silence as dangerous and trigger more open communication with sons and daughters. Mothers hope to break the cycle of unwanted pregnancy by speaking with daughters about the consequences of menstruation and with sons about contraception.

Structure of cartoons,narrative skills and perception of values/countervalues in primary school / Estructura de los dibujos animados,habilidades narrativas y percepción de valores/contravalores en Educación Primaria

Abstract

This study analyses whether narrative skill and the perception of values/countervalues among students in primary school vary according to the structure (narrative vs non-narrative) of the episodes of fiction viewed, the grade age (third and sixth, 8–12 years old), sex and attentional level. With this purpose in mind, quantitative and qualitative methodologies were implemented. The most noteworthy results include the higher narrative skill and perception of values/countervalues of students in the sixth grade of primary school and those who viewed an episode with a narrative structure. The conclusion is that when addressing narrative skills and the education in values/countervalues from the formal and informal spheres, special importance should be attached to the structure of the fiction contents, given that it can to some extent help students make the messages meaningful in terms of values and countervalues.     

Agents control in intelligent learning systems: The case of reactive characteristics

Intelligent learning systems (ILSs) have evolved in the last few years basically because of influences received from multi-agent architectures (MAs). Conflict resolution among agents has been a very important problem for multi-agent systems, with specific features in the case of ILSs. The literature shows that ILSs with cognitive or pedagogical agents are prone to arbitration methods, where as ILSs with reactive agents are much in favor of control mechanisms. For these kind of systems, different control types are proposed based on the different stimuli that these agents will receive. These stimuli are aspects to be evaluated during the teaching/learning process such as: (1) error analysis, (2) learning styles, (3) analogies, (4) social aspects, etc.

The paper reviews several ILSs, related to our work; different control mechanisms are proposed to solve the agents' intervention conflicts. Finally, the use of several mechanisms is exemplified by the results of a specific ILS.     

Secondary School Students’ Construction and Use of Mathematical Models in Solving Word Problems

This study focussed on how secondary school students construct and use mathematical models as conceptual tools when solving word problems. The participants were 511 secondary-school students who were in the final year of compulsory education (15–16 years old). Four levels of the development of constructing and using mathematical models were identified using a constant-comparative methodology to analyse the student’s problem-solving processes. Identifying the general in the particular and using the particular to endow the general with meaning were the key elements employed by students in the processes of construction and use of models in the different situations. In addition, attention was paid to the difficulties that students had in using their mathematical knowledge to solve these situations. Finally, implications are provided for drawing upon student’s use of mathematical models as conceptual tools to support the development of mathematical competence from socio-cultural perspectives of learning.     

Accelerated degrees in education: a new profile,alternative access to teaching or part of a re-tooling process?

In the UK, the provision of accelerated undergraduate programmes is responding to the needs of an increasingly diverse and career-focused student body and a flexible, ever-changing labour market. These fast track degrees are particularly new in education where recent developments in school autonomy and teacher training have had consequences on the design and delivery of programmes, definition of professional profiles and implications for the future of education as a subject of study in universities. This article portrays a small-scale research study about the views of students undertaking a new two-year accelerated degree in one English university using surveys at the beginning and end of the first academic year. The great majority were not planning to attend the programme but have chosen it for its career options and for being a quicker and cheaper route to access a degree – with teaching as the career goal. After one year, students reported gains in knowledge and skills, recommended the programme and kept their intention to pursue a career in teaching. Overall, we address a gap in the literature and start the discussion about the (dis)association between the students’ career routes and goals, the provision of these programmes and the teacher training offers.     

Simulation framework for teaching in modeling and simulation areas

Simulation is the process of executing a model that describes a system with enough detail; this model has its entities, an internal state, some input and output variables and a list of processes bound to these variables. Teaching a simulation language such as general purpose simulation system (GPSS) is always a challenge, because of the way it executes the models and the abstraction level it can achieve, very different compared with most well-known programming languages. This article presents an open source simulation framework that implements a subset of entities of GPSS, which could help students to improve the understanding of this language. This tool also stores all entities of simulations in every single simulation time, which is very useful for debugging simulations, but also for getting a detailed history of all entities in the simulations, knowing exactly how they have behaved in every simulation time.
