Modelling TIMSS Data in a European Comparative Perspective: Exploring Influencing Factors on Achievement in Mathematics in Grade 8

In international comparative studies like TIMSS data analysis is aimed at differences and similarities among education systems (countries). In this article the outcomes are presented of explorative path analysis on data collected with grade 8 students and classrooms in eight Western and two Central European education systems. For the 10 education systems the resulting general path model explains 19% or less of the variance in achievement in mathematics. In many systems home educational background and students’ attitude towards mathematics have a positive relation with achievement in mathematics, out-of-school activities a negative. Due to the psychometric quality of scales and non-availability of measures of important factors at classroom level (e.g., time on task and teacher’s expectation), no significant results were found of factors that can be manipulated by policy makers.     

The quality of student ratings of teacher behaviour

In a research project into the effectiveness of mathematics teaching in the first year of secondary education, external observers and students rated teachers' behaviour. The reliability and validity of both methods were established. The results show that teacher behaviour is assessed well when student ratings are aggregated at the classroom level. The quality of aggregated student ratings is as good as the quality of data from external observers. The predictive validity of aggregated student ratings is higher than the predictive validity of external observations when subject motivation is taken as a dependent variable.     

Development and evaluation of a student-centred multimedia self-assessment instrument for social-communicative competence

Communication plays an important role in manyprofessional contexts. This is especially truefor students in the field of social work. Theaim of this study was to develop formative,self-regulated multimedia self-assessment ofsocial-communicative competencies for socialwork students. First, a pilot study wasconducted to gain insight into the students'specific characteristics. This insight was usedto design guidelines for the development of theassessment instrument in order to tune these tothe students' perceptions, instructionalpreferences, and personalities and thusenhancing the students' enthusiasm to use theself-assessment instrument. This might increasethe chance for successful implementation ofthis new form of assessment.A first version of a multimedia test wasdeveloped. A quality expert meeting wasorganised to gain insight into expertjudgements on the quality of the test and toobtain indications for improvement of theassessment. A second version of the test wasconstructed and put on the Internet. Nearly 400students completed the assessment and expressedtheir opinions on this new way of communicationassessment.We found it was possible to testsocial-communicative competence by means ofmultimedia, with the help of digital video. Theuse of Internet makes assessments available atany time to fit curriculum needs and alsoresolves time and space constraints. Ourconclusion was that the multimedia test isreasonably valid. All students reported havingliked the multimedia assessment.     

Understanding teachers’ professional learning goals from their current professional concerns

In the day-to-day workplace teachers direct their own learning, but little is known about what drives their decisions about what they would like to learn. These decisions are assumed to be influenced by teachers’ current professional concerns. Also, teachers in different professional life phases have different reasons for engaging in professional learning. In this study, we explored the professional concerns underlying teachers’ learning goals in order to understand variation in professional learning over a teacher’s career. In this qualitative study, we administered a semi-structured interview and a card sorting task to 15 secondary school teachers to elicit teachers’ learning goals and current professional concerns. By conceptually combining teachers’ learning goals with professional concerns in concern-goal pairs, we sought to understand the different reasons for teachers’ learning. These concern-goal pairs were characterized in three different types of reasons: continuous, growth and improvement, and work-management. The results showed that early career teachers have mainly growth and improvement concerns, whereas mid- and late-career teachers have both continuous and growth and improvement concerns. Work-management concerns differ for early- and late-career teachers. Results are further discussed in terms of professional life phase models and teachers’ developmental tasks throughout their career.     

Identification of red colorants in van Gogh paintings and ancient Andean textiles by microspectrofluorimetry

Red lake pigments and dyes used in works of art were characterized by microspectrofluorimetry, a new tool in the field of cultural heritage. Emission and excitation spectra were obtained with high spatial resolution (8–30 μm) in cross-sections from paintings by Vincent van Gogh and Lucien Pissarro and from millenary Andean textiles. The fluorophores were identified by comparing their spectra with those from historic reconstructions assembled in a database. In the paints, purpurin and eosin lakes were detected. In the Paracas and Nasca textiles, dated from 200 B.C. to A.D.1476, purpurin and pseudopurpurin were the red dyes used. Carminic acid was detected in textiles dated close to the Inca Empire, A.D. 1000–1476. The results obtained with this new technique were confirmed and are in agreement with those obtained with conventional methods, requiring microsampling, such as HPLC-DAD-MS and SEM-EDX.     

Delimiting Coefficient α from Internal Consistency and Unidimensionality

I discuss the contribution by Davenport, Davison, Liou, & Love (2015) in which they relate reliability represented by coefficient α to formal definitions of internal consistency and unidimensionality, both proposed by Cronbach (1951). I argue that coefficient α is a lower bound to reliability and that concepts of internal consistency and unidimensionality, however defined, belong to the realm of validity, viz. the issue of what the test measures. Internal consistency and unidimensionality may play a role in the construction of tests when the theory of the attribute for which the test is constructed implies that the items be internally consistent or unidimensional. I also offer examples of attributes that do not imply internal consistency or unidimensionality, thus limiting these concepts' usefulness in practical applications.

Measuring general and specific stress causes and stress responses among beginning secondary school teachers in the Netherlands

The main aim of this study was to adjust the Questionnaire on the Experience and Evaluation of Work (QEEW) in order to measure stress causes and stress responses of beginning secondary school teachers in the Netherlands. First, the suitability of the original QEEW stress scales for use in the beginning teachers (BTs) context was investigated using a sample of 356 beginning teachers from 52 different secondary school locations in the Netherlands. Confirmatory Factor Analyses, Principal Component Analyses and Mokken scaling item reduction was applied to create high concise and precise scales. Hereafter, based on the teacher stress literature, additional teacher specific stress items were added, resulting in the adjusted version of the measure, the Questionnaire on the Experience and Evaluation of Work – Beginning Teachers (QEEW-BT, study 1). To cross-validate the results and to examine the internal consistency and validity of the adjusted instrument a different sample of 143 beginning teachers from 61 different secondary school locations in the Netherlands was used (study 2). The present findings provide adequate support that the QEEW-BT is a reliable and valid instrument to measure stress causes and responses for beginning secondary school teachers in the Netherlands.     

The relationship between beginning teachers’ stress causes,stress responses,teaching behaviour and attrition

In this study, the relationships between beginning teachers’ perceived stress causes, stress responses, observed teaching behaviour and attrition is investigated employing structural equation modelling (SEM). A total of 143 BTs were surveyed using the Questionnaire on the Experience and Evaluation of Work-BTs (QEEW-BT). Teaching behaviour was observed using the ICALT observation instrument. Results show that BTs’ perceived negative pupil aspects relate positively to the stress responses perceived tension, discontent and negative emotions. Negative emotions, in turn, are negatively associated with observed teaching behaviour. This study also shows that discontent positively relates to attrition. Additionally, this study provides important cues to improve professional support programmes for BTs.     

Teacher agency within the context of formative teacher assessment: an in-depth analysis

Teachers’ agency has an effect on their own learning process at the workplace. In this study we explored the extent to which teachers participating in a formative teacher assessment procedure developed a sense of agency. We investigated not only whether teachers participating in a such an assessment procedure experienced agency and thus felt in control of the learning process and able to pursue their learning objectives, but also whether agency was visible, by looking at decision-making in real time: did teachers take an active role in their own assessment, especially regarding the learning objectives to be pursued, during the assessment meetings? We found that teachers experienced a high level of agency while participating in the assessment procedure, but did not consistently show this during the assessment procedure.
