In the workplace mathematics does not announce itself: towards overcoming the hiatus between mathematics education and work

After improving enrolment rates significantly, many developing countries such as Peru are facing the challenge to increase learning levels among students. Over the past few years, many researchers have turned to teacher-related variables as a way to better understand classroom processes that may help increase learning levels among students. In this study, we analyze one of these, that falls under what Shulman (Educational Researcher, 15 (2), 4–14, 1986) called pedagogical content knowledge (PCK). Specifically, in this study, we analyze one of the areas of PCK which is knowledge of content and students. This was measured through a test where teachers were asked to explain students’ mistakes and predict responses in similar mathematics exercises. We explore if PCK is associated with the socioeconomic status of children and if it has an effect on children’s achievement. Additionally, we analyze which teacher characteristics are associated with higher scores in PCK. The analysis uses the Young Lives longitudinal survey for Peru. We found that students’ socioeconomic status at age 1 and maternal education were positively associated with their teachers’ PCK by the time students were enrolled in fourth grade, thus depicting a very unequal education system. Furthermore, teachers’ PCK was positively associated with student achievement, but only when a threshold for the PCK test was established. For our sample, male teachers, who were younger, and Spanish speakers had higher PCK scores.     

Developmental Changes in Event Memory

Do developmental differences exist in children's organization of event memories? We explored this question by examining children's recall of standard features of a repeated event versus features that deviated from that event. 4- and 7-year-old children experienced an initially unfamiliar laboratory event (standard event) 1 or 3 times. Following the last visit, deviations from the standard event were introduced (deviation event). Children's recall was assessed 1 week later under free recall and contextual recall conditions. Younger children had more difficulty than older children distinguishing between the standard and deviation visits. That is, 4-year-olds were more confused regarding which event features occurred in the different event visits. 7-year-olds, in contrast, did a better job of correctly remembering the features of the standard and deviation visits. Implications for developmental changes in the organization of general and specific event memory are discussed.     

Effort–reward imbalance and overcommitment in UK academics: implications for mental health,satisfaction and retention

This study utilises the effort–reward imbalance (ERI) model of job stress to predict several indices of well-being in academics in the UK: mental ill health, job satisfaction and leaving intentions. This model posits that (a) employees who believe that their efforts are not counterbalanced by sufficient rewards will experience impaired well-being and (b) feelings of ERI are more frequent and damaging in employees who are overcommitted to the job. A sample of 649 academic employees working in UK higher education institutions completed validated measures. Findings showed that academics who found their work more demanding, who perceived greater rewards and who were less overcommitted typically reported poorer well-being across all measures. Rewards related to esteem/support and financial/status appeared to be particularly important in protecting academics from the negative impact of work-related efforts. Potential interventions are discussed that draw on the ERI framework to improve mental health, satisfaction and retention in the sector.     

Building teacher capacity for implementing curricular coherence: mathematics teacher professional development tasks

Improving mathematics education in the United States has taken many forms. Our work has focused on two aspects: the content knowledge of teachers and a well-articulated coherent curriculum. Our aim was teacher “capacity building” that is enabling teachers to teach to coherent and significant mathematical curricular goals and describe the implementation in a large-scale project based at Michigan State University. We highlight the design, structure and use of mathematics teacher learning tasks that were intended to improve teachers’ capacity to teach to these goals and note how the teachers’ perceptions of the structure and sequencing of mathematics itself affect the ways they organize mathematics in their teaching and the ways they teach.     

Effects of ICT: Do we know what we should know?

Many decades after the introduction of ICT into classrooms there are still unanswered questions about the impact of technology in the long and short term on students’ learning, and how it has affected simple and complex learning tasks. These are important for (a) forming government policies; (b) directing teacher education programmes: (c) advancing national curricula; (d); designing or reforming classroom implementation and (e) analysing costs and benefits. While a plethora of studies has been conducted on the effects of ICT in education, major policy and methodological problems have precluded an unambiguous answer to such questions as:—“Does the way in which ICT is implemented have a major/minor impact on students’ knowledge and understanding?” and “Does the impact affect the surface or deep structure of students’ thinking and acting?” To date we have had no large-scale longitudinal studies of ICT’s impact in education such as we have in the form of studies of earlier major curriculum development projects. Nor have we had many comprehensive studies of the complex interactions between various types of ICT implementation and the effects of other factors such as school-based interventions, socio-economic status and school expenditures which have been shown to have a greater impact on education compared with other previous innovations in education. Furthermore we do not know if previous research studies have used research methods that matched learning objectives to instruments/procedures. Many previous studies are vague as to the actual measures used but we can infer that standardized tests were a frequent measure. In other instances, ad hoc analyses, with criteria that may have varied from analyst to analyst and were not “blind” analyses were certainly used to measure “success.” All of these limitations and uncertainties and many more point to the need for a thorough, rigorous, and multifaceted approach to analysing the impact of ICT on students’ learning. This paper draws on previous research evidence to identify relevant research strategies to address the gaps in our knowledge about ICT and students’ learning explained above.     

Communication in spiders

As in other animals, the exchange of signals between spiders serves many purposes and in recent years it has been shown that they have evolved a very complex system. This includes the exchange of information by acoustic/vibratory mechanisms; by visual means; and by pheromones. This article reviews these systems and the circumstances in which they are brought into play.
