Transitioning to agile software development: Lessons learned from a government-contracted program

With a need to implement an agile software development methodology in government programs, this study was conducted to explore how organizations transitioned from a traditional waterfall software development method to agile methods. To accomplish this study, a case study research was utilized. A multimillion-dollar government-contracted program in the US was studied. The research findings reveal key challenges faced by organizations during the transition and the lessons learned that can be applied to future programs. Propositions for future research are also presented.     

Prediction of adult height in girls: the Beunen-Malina-Freitas method

The purpose of this study was to validate and cross-validate the Beunen-Malina-Freitas method for non-invasive prediction of adult height in girls. A sample of 420 girls aged 10-15 years from the Madeira Growth Study were measured at yearly intervals and then 8 years later. Anthropometric dimensions (lengths, breadths, circumferences, and skinfolds) were measured; skeletal age was assessed using the Tanner-Whitehouse 3 method and menarcheal status (present or absent) was recorded. Adult height was measured and predicted using stepwise, forward, and maximum R (2) regression techniques. Multiple correlations, mean differences, standard errors of prediction, and error boundaries were calculated. A sample of the Leuven Longitudinal Twin Study was used to cross-validate the regressions. Age-specific coefficients of determination (R (2)) between predicted and measured adult height varied between 0.57 and 0.96, while standard errors of prediction varied between 1.1 and 3.9 cm. The cross-validation confirmed the validity of the Beunen-Malina-Freitas method in girls aged 12-15 years, but at lower ages the cross-validation was less consistent. We conclude that the Beunen-Malina-Freitas method is valid for the prediction of adult height in girls aged 12-15 years. It is applicable to European populations or populations of European ancestry.     

Questionnaire on Perceived Competency-based Learning for primary school students (#ICOMpri1) / Cuestionario del Aprendizaje Percibido basado en Competencias para el Alumnado de Educación Primaria (#ICOMPri1)

The purpose of this study was to design and validate an assessment tool to find out how primary school students perceive their competency-based learning. By examining the content validity (n = 35 experts), comprehension (n = 173 students) and construct (n = 523 students) of the instrument, the results showed correct psychometric quality, internal consistency, reliability and adequacy of the structural model: χ²/df = 2.08, TLI = 0.88, CFI = 0.90, GFI = 0.90, RMSEA = 0.04, and SRMR = 0.04. The final version of the Questionnaire on Perceived Competency-based Learning of primary school students (#ICOMpri1) includes eight dimensions and 27 items. The results showed a high perceived competency-based learning of primary school students. This is therefore a valid and reliable instrument that provides a more subjective and real vision of primary students’ academic performance. Nevertheless, future studies should analyse the criterion-related validity by comparing perception results with those of international academic achievement.     

Implementation of a project-based engineering school: increasing student motivation and relevant learning

The School of Engineering at Universidad Europea de Madrid (UEM) implemented, starting in the 2012–2013 period, a unified academic model based on project-based learning as the methodology used throughout the entire School. This model expects that every year, in each grade, all the students should participate in a capstone project integrating the contents and competencies of several courses. This paper presents the academic context under which this experience has been implemented, and a summary of the work done to design and implement the Project-Based Engineering School at the UEM. The steps followed, the structure used, some sample projects, as well as the difficulties and benefits of implementing the programme are discussed in this paper. The results are encouraging as students are more motivated and the initial set objectives were accomplished.     

Promoting Gypsy children's behavioural engagement and school success: Evidence from a four‐wave longitudinal study

Low schooling, high non‐attendance and school dropout rates are critical phenomena within disadvantaged groups, especially among the Gypsy community. For example, in the UK, 10%–25% of Gypsy children do not attend school regularly and have significantly higher levels of overall absence from school (percentage of half‐day sessions missed) than pupils from other ethnic groups. In Portugal, available data on Gypsy children is sparse, yet data from one geographic region of the country reports high school failure (45%) and dropout rates (15%) among this population. The present study assessed the efficacy of a four‐year intervention to promote Gypsy children's behavioural engagement and school success. Gypsy communities were contacted and 30 children participating in the four waves were randomly distributed into control and experimental groups. Every school day throughout four years, 16 children in the experimental group were called at home and invited to go to school. The effectiveness of the intervention was evaluated in four waves (at the end of each of the four school years), assessing behavioural engagement (i.e. school non‐attendance, classroom behaviour) and school achievement (i.e. mathematics achievement, student progression). Findings show the efficacy of the intervention on promoting behaviour engagement and academic success without devaluing Gypsy people's culture.     

SCHOOL PSYCHOLOGISTS’ FAMILY–SCHOOL PARTNERING EXPERIENCES WITH LATINOS

The purpose of this phenomenological study was to identify the beliefs, perceptions, and actions of school psychologists toward family–school partnering (FSP) with Latino families in the public school system. Existing research in this area is extremely limited; therefore, the present study has significant implications for pre‐ and in‐service training to achieve effective FSP with Latino families. Five school psychologists working in school districts with greater than 40% Latino student enrollment participated in this study. Five major themes emerged from data analysis: Attitudes toward FSP, Knowledge and Skills Needed, Expectations for Engagement, Perceived Barriers to FSP, and Engagement Activities. The results of this study will help researchers and educators develop an awareness of the challenges school psychologists face and the actions they take to enhance relationships with Latino families.     

Implementing Key Competences in Basic Education: reflections on curriculum design and development in Spain

The concept of competence is a recent introduction into the curricula of the Spanish education system, and applies to vocational training and university, but also to basic education. In both cases, the meaning and use of the term have differed, sometimes giving rise to confusion. There can be no doubt, however, that this incorporation has been of significant impact. On the one hand, it has generated considerable debate between those who consider the concept to respond to economistic arguments, removed from educational realities, and those who believe it to have a transformation potential that cannot be ignored. On the other, incorporation of the concept is leading to a series of modifications in school practices and in teaching and learning with whose consequences we are not yet acquainted. This article analyses the situation created by the introduction of key competences in Spanish compulsory education and seeks to gauge the potential this offers for improving opportunities for success at school. The authors believe that key competences are a reformulation of educational intentions, whose consequences for schools and teaching practices largely depend on the new interpretation of learning in the light of different approaches and research traditions.
