Identifying threshold concepts in the careers of educational developers

The purpose of this multiple case study was to identify threshold concepts in the careers of educational developers. Twenty-one common threshold concepts emerged, with one threshold concept common among all participants: Facilitating a change process. The remaining 20 threshold concepts were captured in the following three categories: (1) Ways of knowing and being that facilitate change in individuals and in groups; (2) Ways of knowing and being that facilitate systemic change and (3) Core ways of knowing and being. Study results may provide guidance for the design of initial and ongoing formation programmes in educational development.     

Differential Effects of Three Teachers Over a Unit of Instruction

The purpose of this study was to describe the effects of three teachers on psychomotor, affective, and cognitive outcomes over a 15-lesson volleyball unit. Three intact middle school physical education classes were used. Pre- and posttests were administered for the overhead set, forearm pass, and serve psychomotor skills. A semantic differential test with four affective dimensions and a written test on the rules, strategies, and mechanics of volleyball were also administered pre- and posttest. Data on instructional characteristics were obtained using academic learning time (ALT-PE); observation system for content development (OSCD-PE), and a content analysis of lessons.

The following were key aspects of the results: (a) Teachers differed in their approaches to the content of the unit more than in the characteristics of their instruction as determined through observational data; (b) teachers differed in respect to the psychomotor skills for which they were able to produce statistically significant student gain; (c) the skill level of students played a major role in psychomotor outcomes; (d) affective measures started high and remained high from pre- to posttest with significant change occurring positively with the low-skilled in one measure; (d) cognitive learning was significant from pre- to posttest in rules and mechanics but not in strategies. Instructional characteristics, as described in this study, did not change from skill to skill, but student learning did. This led the authors to conclude that the instrumentation for instructional variables was not sensitive to differences in the way individual skills were handled by individual teachers.     

The effects of teacher expectation interventions on teachers’ expectations and student achievement: narrative review and meta-analysis

ABSTRACT

This study provides a systematic review of the effects of 19 teacher expectation interventions. Prior research on teacher expectations primarily focussed on correlational relationships with student and teacher characteristics, leaving open the questions of whether it is possible to raise teacher expectations and to prevent (too) low expectations from having detrimental effects on student achievement. These questions were the scope of the current review. We distinguished 3 types of interventions: changing teacher behaviour, creating awareness of expectancy effects, and addressing the beliefs underlying the expectations. The results indicated that it was possible to raise teacher expectations and subsequent student achievement. We found summary effects of Hedges’ g?=?0.38 and 0.30, respectively. The narrative review suggested that the intervention type did not affect the effectiveness, but teacher support for the intervention did. However, verification of this suggestion with moderator analysis was not possible due to the limited number of interventions.     

A black technician and blue babies

In this paper, I discuss the many contributions of a versatile black technician, Vivien Thomas, to surgical animal research between 1930 and 1979 at Vanderbilt University and Johns Hopkins University. Thomas' experimental work led to a surgical solution for a life-threatening heart defect, called tetralogy of Fallot. Children with this condition lack sufficient oxygenation and were referred to as 'blue babies'. Following Thomas' research trajectory and his relationship with surgeon Dr Alfred Blalock, I review the conditions under which differing expectations towards race and occupation clashed, creating a status dilemma for Thomas. While the torsion originated in the laboratory where technical skills are valued, the research locale also facilitated a temporary, fragile solution for the status dilemma, because it separated Thomas from public view. Yet, Thomas' dexterity as a laboratory researcher enhanced his dilemma, because credit kept eluding him. In order to track the dynamics of race and occupational subordination as lived experience in the laboratory, I argue for an analysis of the process of crediting people for their scientific accomplishments.     

Dominant achievement goals and academic outcomes across tracks in high school

The self-reported grades Dutch, English and Math of 13,970 students in the third grade of Dutch secondary education (US grade 9) were investigated with regard to educational track-level and dominant achievement goal (DAG). The performance approach goal group scored significantly higher on all three subjects than the performance avoidance group, the mastery approach group, the mastery avoidance group and the group without a DAG. In addition, the differences between the performance approach group and the other groups with regard to the three school subjects were of the same size, suggesting that the DAG is associated with the same processes across various school subjects. The magnitude of the differences between the other DAG groups, however, decreased with decreasing track level, suggesting that the DAGs’ adaptive value varies systematically with ability level.     

Value added based on educational positions in Dutch secondary education

Estimating added value as an indicator of school effectiveness in the context of educational accountability often occurs using test or examination scores of students. This study investigates the possibilities for using scores of educational positions as an alternative indicator. A number of advantages of a value added indicator based on educational positions of students can be formulated, such as: (a) the societal significance of educational position as output measure; (b) the fact that a single indicator can be estimated for an entire school in a differentiated educational system, where not all schools provide education in all tracks; and (c) the expectation that value added based on educational positions leads to other incentives for schools than value added based on test scores. Empirical analysis of Dutch cohort data (VOCL'99) for secondary education showed considerable differences in effectiveness between schools in the positions of students. Furthermore, differential school effects were found for both socio‐economic status and prior achievement. The phenomena of differential school effects for socio‐economic status and prior achievement are linked to differences between schools in the kind of tracks in which the schools provide schooling.     

A framework for working with university teachers to create and embed ‘Integrated Threshold Concept Knowledge’ (ITCK) in their practice

Abstract

In this paper, we propose a framework to help educational developers navigate the now vast literature on threshold concepts, so that they may effectively support university teachers in their work to embed threshold concept knowledge into courses and programs. This research- and practice-informed framework consists of seven principles and seven clusters of activities. It includes an ‘actionable literature review’ – a distillation and synthesis of threshold concept-related knowledge that can be acted upon and adapted in a variety of settings by educational developers and teachers.
