Does the EDI Measure School Readiness in the Same Way Across Different Groups of Children?

The present study investigates whether the Early Development Instrument (Offord & Janus, 1999) measures school readiness similarly across different groups of children. We employ ordinal logistic regression to investigate differential item functioning, a method of examining measurement bias. For 40,000 children, our analysis compares groups according to gender, English-as-a-second-language (ESL) status, and Aboriginal status. Our results indicate no systematic measurement differences regarding Aboriginal status and gender, except for 1 item on which boys are more likely than girls to be rated as physically aggressive by Kindergarten teachers. In contrast, ESL children systematically receive lower ratings on items of the language and communication domains—as expected by definition of ESL status—but not within the physical, social, and emotional domains. We discuss how our results fit with child development research and the purpose of the Early Development Instrument, thus supporting its validity.     

Learning from texts: activation of information from previous texts during reading

Learning often involves integration of information from multiple texts. The aim of the current study was to determine whether relevant information from previously read texts is spontaneously activated during reading, allowing for integration between texts (experiment 1 and 2), and whether this process is related to the representation of the texts (experiment 2). In both experiments, texts with inconsistent target sentences were preceded by texts that either did or did not contain explanations that resolved the inconsistencies. In experiment 1, the reading times of the target sentences introducing inconsistencies were faster if the preceding text contained an explanation for the inconsistency than if it did not. This result demonstrates that relevant information from a prior text is spontaneously activated when the target sentence is read. In experiment 2 free recall was used to gain insight into the representation after reading. The reading time results for experiment 2 replicated the reading time results for experiment 1. However, the effects on reading times did not translate to measurable differences in text representations after reading. This research extends our knowledge about the processes involved in multiple text comprehension: Prior text information is spontaneously activated during reading, thereby enabling integration between different texts.     

Gender norms and STEM: the importance of friends for stopping leakage from the STEM pipeline

More women are now entering male-dominated fields, yet, science, technology, engineering, and mathematics (STEM) remain dominated by men. We examined the association between boys’ and girls’ STEM choices after secondary education and friends’ gender norms, and whether pressure to conform to traditional gender norms differs depending on the gender composition of the friend group. Drawing on 3 waves of longitudinal data (N?=?744) from the Netherlands, our sample consists of adolescents in STEM trajectories in secondary education. Their retention in STEM after secondary education gives us a better understanding of gender-specific “leakage” from the STEM pipeline. We found that girls’ likelihood of choosing STEM decreased drastically when friends had more traditional gender norms. Friends with traditional gender norms had less effect on boys. Nonetheless, boys with only same-sex friends were more likely to enter STEM. Our findings indicate that an environment with gender-normative ideas pushes girls out of the STEM pipeline.     

Strategies of Number Sense in Pre-service Secondary Mathematics Teachers

This paper presents some results of an investigation on the number sense of a group of pre-service secondary teachers from Spain. The objective of this research was to analyze students’ use of strategies associated to number sense and compare them with those obtained in a previous study with pre-service primary teachers in Taiwan, (Yang, Reys & Reys, International Journal of Science and Mathematics Education, 7, 383–403, 2009). Pre-service secondary teachers showed lower success than pre-service primary teachers in a number sense test. Nevertheless, these last based their reasoning mainly on rules and algorithms, while pre-service secondary teachers used more strategies of number sense. In an attempt to delve into the low success shown by of Spanish pre-service secondary teachers, some students were interviewed. Those interviews showed that a deeper work on number sense in the training of these students is needed.     

Teachers’ professional learning goals in relation to teaching experience*

In this study, we explored the relationships between teachers’ self-articulated professional learning goals and their teaching experience. Although those relationships seem self-evident, in programmes for teachers’ professional development years of teaching experience are hardly taken into account. Sixteen teachers with varying years of experience and subjects were interviewed. The results show different learning goals, related to communication and organisation, curriculum and instruction, innovation, responsibilities, and themselves as professional. Various relationships between learning goals and teaching experience emerged, which clearly reflect the development from early- to mid- and late-career teachers. Issues related to curriculum and instruction appeared to be learning goals for early- and mid-career teachers. This implies that regardless of increasing teaching expertise, curriculum and instruction remain central to teachers’ continuous learning. Late-career teachers were interested in learning about extra-curricular tasks and innovations. Models of professional life phases have been used to interpret these results.     

Testing the effectiveness of classroom formative assessment in Dutch primary mathematics education

Classroom formative assessment (CFA) is considered to be a fundamental part of effective teaching, as it is presumed to enhance student performance. However, there is only limited empirical evidence to support this notion. In this effect study, a quasi-experiment was conducted to compare 2 conditions. In the treatment condition, 17 teachers implemented a CFA model containing both daily and weekly goal-directed instruction, assessment, and immediate instructional feedback for students who needed additional support. In the control condition, 17 teachers implemented a modification to their usual practice. They assessed their students’ mastery of learning goals on the basis of half-yearly mathematics tests, and prepared weekly pre-teaching sessions for groups of low-achieving students. The posttests showed no significant differences in student performance between the 2 conditions after controlling for student and teacher characteristics. The degree of implementation of the CFA model, however, appeared to be positively related to the 5th-grade students’ performance.     

Localising and tailoring research evidence helps public health decision making

Background

Published research evidence is typically not readily applicable to practice but needs to be actively mobilised.

Objectives

This paper explores the mechanisms used by information professionals with a specific knowledge mobilisation role to make evidence useful for local decision making and planning of public health interventions.

Methods

Data are drawn from a NIHR project that studied how, when, where and by whom published research evidence is used in commissioning and planning across two sites (one in England and one in Scotland). Data included 11 in‐depth interviews with information professionals, observations at meetings and documentary analysis.

Results

Published research evidence is made fit for local commissioning and planning purposes by information professionals through two mechanisms. They localise evidence (relate evidence to local context and needs) and tailor it (present actionable messages).

Discussion

Knowledge mobilisation roles of information professionals are not recognised and researched. Information professionals contribute to the ‘inform’ and ‘relational’ functions of knowledge mobilisation; however, they are less involved in improving the institutional environment for sustainable knowledge sharing.

Conclusion

Information professionals are instrumental in shaping what evidence enters local decision making processes. Identifying and supporting knowledge mobilisation roles within health libraries should be the focus of future research and training.

     

Bias vs. Bias

When Pope Francis, the leader of the Roman Catholic Church, released his encyclical on climate change in June 2015, the Fox News Channel, the most watched cable news network in the United States, faced a dilemma. Some of its news anchors and regular commentators are Catholics, and therefore have a positive bias for the Pope. But the network is also known for its bias against man-made climate change. Guided by cognitive dissonance theory, this study analyzed how Fox News’ anchors and commentators discussed Pope Francis’ stance on climate change. The analysis found a clear ambivalence in their discourse and identified four discursive strategies that they used to navigate discursive dissonance.
