‘Collaborate to graduate’: what works and why?

ABSTRACT

Collaboration is recognised as valuable in enhancing students’ learning as well as their social integration and sense of belonging at an institution, which lead to higher retention rates. We investigate the informal, self-organised collaborative practices of military and civilian engineering students in out-of-class settings using a mixed-methods approach including a weekly survey and in-depth interviews. We find that these students collaborate frequently and pervasively and have developed informal codes of ethics around sharing. Most of the students believe that collaboration with peers is the most effective form of study support. However, we also find that some students may remain isolated. The aspects of the institution and the engineering programme that support these collaborative processes are identified. These aspects include the concurrent military training, which fosters a collaborative rather than competitive or individualistic culture, residential accommodation, and the type of assessment used in engineering. Implications for non-military campuses are discussed.     

Veteran teachers’ job satisfaction as a function of personal demands and resources in the relationships with their students

Many teachers experience their profession as stressful, which can have a negative impact on their job satisfaction, and may result in burnout, absenteeism, and leaving the profession. The relationship with students can have both positive and negative implications for the job satisfaction of teachers, both early and later in their careers. The current study focused on the relationship between veteran teachers’ job satisfaction and their aspirations in teacher-student relationships. Data were gathered among 12 Dutch veteran secondary school teachers, including interviews, the Questionnaire on Teacher Interaction, and the Questionnaire on Teachers’ Self-Efficacy. Veteran teachers’ job satisfaction appeared to be positively related to the extent to which their aspirations in teacher-student relationships had been realized. Teachers who had failed to realize their aspirations in teacher-student relationships showed relatively low job satisfaction, or avoided feelings of low job satisfaction by reducing the number of tasks that were directly related to teaching students. An implication for coaching veteran teachers is the need to pay more attention to the teacher-student relationship so that they can adhere to the way they would like to teach students.     

Visual performance of adults with prelingual auditory impairment

Reaction times and picture evaluations by 18 adults with hearing loss were compared with those of 18 matched controls during two visual priming tasks. In Task 1, participants reacted to sexual and plant target pictures (while influenced by similar preceding pictures) by pressing "sex" or "plant" buttons. In Task 2, they evaluated target Japanese ideographs (while influenced by preceding positive or negative facial expressions as prime pictures) by pressing "positive" or "negative" buttons. In Task 1, the controls had the faster responses. In Task 2, they showed the usual congruent priming effect during very short prime presentations. Participants with hearing loss showed this effect only during short and long prime presentation times; thus, they were not superior to the controls in picture recognition, instead showing (a) impaired processing of visual information or (b) impaired perceptual-motor skills regarding quick responses to visual information (or both).     

Building Latent Class Growth Trees

Researchers use latent class growth (LCG) analysis to detect meaningful subpopulations that display different growth curves. However, especially when the number of classes required to obtain a good fit is large, interpretation of the encountered class-specific curves might not be straightforward. To overcome this problem, we propose an alternative way of performing LCG analysis, which we call LCG tree (LCGT) modeling. For this purpose, a recursive partitioning procedure similar to divisive hierarchical cluster analysis is used: Classes are split until a certain criterion indicates that the fit does not improve. The advantage of the LCGT approach compared to the standard LCG approach is that it gives a clear insight into how the latent classes are formed and how solutions with different numbers of classes relate. The practical use of the approach is illustrated using applications on drug use during adolescence and mood regulation during the day.     

The triangel (socio-therapeutical institute)

We have given a brief outline of the work which is being done at the Triangel. We do not pretend to present a report based on a scientific justification. The aid we give seems to be better described as “the arm around the shoulder of someone in distress” than by the use of precise scientific terms. The common, natural reaction to a disturbed person is a spontaneous gesture of help. We should not try to classify him, or to adopt an attitude of cool scientific interest. The natural, instinctive approach seems to us the most obviously supportive and in this respect the Triangel would seem to serve as a model for all assistance agencies.     

A research model for the study of science teachers’ PCK and improving teacher education

In this article, a new research model for the study of pedagogical content knowledge (PCK) is presented which aims to improve teacher education. This model called “educational reconstruction for teacher education” (ERTE) represents the framework for an integrative approach to the study of science teachers’ topic specific PCK, which is a largely unexplored field. By integrating the PCK concept, originating in the American Curriculum tradition, into the German (Fach)didaktik tradition, this model adds a new perspective to (Fach)didaktik. This paper, therefore, also aims to clarify the PCK concept and its relation to Fachdidaktik.     

Supporting hypothesis generation by learners exploring an interactive computer simulation

Computer simulations provide environments enabling exploratory learning. Research has shown that these types of learning environments are promising applications of computer assisted learning but also that they introduce complex learning settings, involving a large number of learning processes. This article reports on an instrument for supporting one of these learning processes: stating hypotheses.The resulting instrument, an hypothesis scratchpad, was designed on the basis of a conceptual representation of the simulation model and tested in an experimental study. In this study three versions of the scratchpad, varying in structure, were compared. It was found that support offered for identifying variables, in the form of a selection list, is relatively successful: students who used this list were better in differentiating different types of variables. For identifying relations, a selection list of relations offered to the students proved unhelpful in finding accurate relations: students using this list stated their hypotheses mainly at a very global level.The research reported was conducted in the project SIMULATE. SIMULATE was part of SAFE, a R&D project partially funded by the CEC under contract D1014 within the Exploratory Action of the DELTA programme. The work of SIMULATE is continued in the DELTA main phase project SMISLE.     

Automatization aspects of dyslexia: speed limitations in word identification, sensitivity to increasing task demands, and orthographic compensation

A study is presented in which three characteristics of dyslexia were examined: (a) speed limitations in word identification, (b) sensitivity to increasing task demands, and (c) orthographic compensation. Ten students with dyslexia (10 years old) were compared to 10 chronological-age controls and 20 reading-age controls on their performance in reading. Response latencies of the students with dyslexia were slower when familiar words, letter clusters, and nonwords had to be named. A larger word-frequency effect and a larger word-length effect in the these students indicates that they have difficulty with increasing task demands. In addition, a subword-frequency effect was found to be larger in the students with dyslexia. These differences among the three groups of students are interpreted in terms of automatization. Furthermore, it is suggested that students with dyslexia may have a preference for large orthographic units, which is used as a compensatory tool in reading.     

Boys’ and girls’ educational choices in secondary education. The role of gender ideology

This study aims to explain why boys and girls in secondary education choose different educational tracks. We argue that adolescents internalise gender expectations as to what is “appropriate” male and female behaviour in their gender ideology. Gender ideology can affect educational choices by influencing (1) how adolescents evaluate their competence in certain subjects (competence beliefs), (2) what they find important in a future occupation (occupational values) and (3) what school subject they prefer right now (subject preferences). Longitudinal data collected among adolescents at age 15 and 16 (N = 1062) are used. Multinomial path models show that gender ideology shapes boys’ occupational values and subject preferences, whereas for girls it shapes their competence beliefs. Only for boys this leads to gender-stereotypical educational choices, however. Our results support the idea that gender expectations are stricter for boys than for girls and may prevent men from entering more feminine career tracks.
