Impact of Student Teaching On the Mathematics Teaching Efficacy Beliefs of Preservice Elementary Teachers
Much attention, both nationally and internationally, has been given to mathematics teaching and student mathematical performance (e.g. No Child Left Behind Act (2001), National Council of Teachers of Mathematics (1991, 2000) standards, Common Core State Standards Initiative, Trend in International Mathematics and Science Study (2013), and Program of International Student Assessment PISA (2013)). Teachers of mathematics have come under greater scrutiny and demands for student success have been placed upon them. Research has shown that teacher efficacy and mathematics teaching efficacy, forms of self-efficacy beliefs (Bandura, 1977, 1997), can have a positive impact on teaching and learning. Yet, there has been limited research on the mathematics teacher efficacy of preservice elementary teachers (Swars, 2005).
This study examined the impact of the student teaching experience on the mathematics teaching efficacy beliefs of preservice elementary teachers. What happens to the level of mathematics teaching efficacy beliefs of preservice teachers during the student teaching experience? What are the characteristics of preservice teachers with low and high levels of efficacy beliefs? What factors from the student teaching experience influenced efficacy beliefs? A qualitative case study (Merriam, 2009) with an embedded survey was used to address the previous questions.
The results of this study demonstrate that mathematics teaching efficacy beliefs of preservice teachers rose significantly during the student teaching experience. However, the change was not uniform. Personal mathematics teaching efficacy (PMTE) increased significantly. Although mathematics teaching outcome expectancy (MTOE) increased, it was not significant. Furthermore, the research indicates four characteristics influenced mathematics teaching efficacy beliefs: attitude toward mathematics, use of manipulatives, motivation to teach, and persistence. Four factors appear to impact the development of efficacy beliefs of preservice teachers: prior experiment with mathematics, student teaching experience, relationship with cooperating teacher, and students served by the preservice teachers

Results from the Wide Angle Search for Planets Prototype (WASP0) II: Stellar Variability in the Pegasus Field
Recent wide-field photometric surveys which target a specific field for long
durations are ideal for studying both long and short period stellar
variability. Here we report on 75 variable stars detected during observations
of a field in Pegasus using the WASP0 instrument, 73 of which are new
discoveries. The variables detected include 16 delta Scuti stars, 34 eclipsing
binaries, 3 BY Draconis stars, and 4 RR Lyraes. We estimate that the fraction
of stars in the field brighter than V ~ 13.5 exhibiting variable behaviour with
an amplitude greater than 0.6% rms is ~ 0.4%. These results are compared with
other wide-field stellar variability surveys and implications for detecting
transits due to extra-solar planets are discussed.Comment: 10 pages, 8 figures, published in MNRA

Effects of antiplatelet therapy on stroke risk by brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases: subgroup analyses of the RESTART randomised, open-label trial
Background
Findings from the RESTART trial suggest that starting antiplatelet therapy might reduce the risk of recurrent symptomatic intracerebral haemorrhage compared with avoiding antiplatelet therapy. Brain imaging features of intracerebral haemorrhage and cerebral small vessel diseases (such as cerebral microbleeds) are associated with greater risks of recurrent intracerebral haemorrhage. We did subgroup analyses of the RESTART trial to explore whether these brain imaging features modify the effects of antiplatelet therapy
Reading and Ownership
First paragraph: âIt is as easy to make sweeping statements about reading tastes as to indict a nation, and as pointless.â This jocular remark by a librarian made in the Times in 1952 sums up the dangers and difficulties of writing the history of reading. As a field of study in the humanities it is still in its infancy and encompasses a range of different methodologies and theoretical approaches. Historians of reading are not solely interested in what people read, but also turn their attention to the why, where and how of the reading experience. Reading can be solitary, silent, secret, surreptitious; it can be oral, educative, enforced, or assertive of a collective identity. For what purposes are individuals reading? How do they actually use books and other textual material? What are the physical environments and spaces of reading? What social, educational, technological, commercial, legal, or ideological contexts underpin reading practices? Finding answers to these questions is compounded by the difficulty of locating and interpreting evidence. As Mary Hammond points out, âmost reading acts in history remain unrecorded, unmarked or forgottenâ. Available sources are wide but inchoate: diaries, letters and autobiographies; personal and oral testimonies; marginalia; and records of societies and reading groups all lend themselves more to the case-study approach than the historical survey. Statistics offer analysable data but have the effect of producing identikits rather than actual human beings. The twenty-first century affords further possibilities, and challenges, with its traces of digital reader activity, but the map is ever-changing
Schoolbooks and textbook publishing.
In this chapter the author looks at the history of schoolbooks and textbook publishing. The nineteenth century saw a rise in the school book market in Britain due to the rise of formal schooling and public examinations. Although the 1870 Education and 1872 (Scotland) Education Acts made elementary education compulsory for childern between 5-13 years old, it was not until the end of the First World War that some sort form of secondary education became compulsory for all children

TOI-836 : a super-Earth and mini-Neptune transiting a nearby K-dwarf
Funding: TGW, ACC, and KH acknowledge support from STFC consolidated grant numbers ST/R000824/1 and ST/V000861/1, and UKSA grant ST/R003203/1.We present the discovery of two exoplanets transiting TOI-836 (TIC 440887364) using data from TESS Sector 11 and Sector 38. TOI-836 is a bright (T = 8.5 mag), high proper motion (âŒ200 mas yrâ1), low metallicity ([Fe/H]ââ0.28) K-dwarf with a mass of 0.68 ± 0.05 Mâ and a radius of 0.67 ± 0.01 Râ. We obtain photometric follow-up observations with a variety of facilities, and we use these data-sets to determine that the inner planet, TOI-836 b, is a 1.70 ± 0.07 Râ super-Earth in a 3.82 day orbit, placing it directly within the so-called âradius valleyâ. The outer planet, TOI-836 c, is a 2.59 ± 0.09 Râ mini-Neptune in an 8.60 day orbit. Radial velocity measurements reveal that TOI-836 b has a mass of 4.5 ± 0.9 Mâ, while TOI-836 c has a mass of 9.6 ± 2.6 Mâ. Photometric observations show Transit Timing Variations (TTVs) on the order of 20 minutes for TOI-836 c, although there are no detectable TTVs for TOI-836 b. The TTVs of planet TOI-836 c may be caused by an undetected exterior planet.Publisher PDFPeer reviewe
TOI-836: A super-Earth and mini-Neptune transiting a nearby K-dwarf
We present the discovery of two exoplanets transiting TOI-836 (TIC 440887364)
using data from TESS Sector 11 and Sector 38. TOI-836 is a bright (
mag), high proper motion ( mas yr), low metallicity
([Fe/H]) K-dwarf with a mass of M and a
radius of R. We obtain photometric follow-up
observations with a variety of facilities, and we use these data-sets to
determine that the inner planet, TOI-836 b, is a R
super-Earth in a 3.82 day orbit, placing it directly within the so-called
'radius valley'. The outer planet, TOI-836 c, is a R
mini-Neptune in an 8.60 day orbit. Radial velocity measurements reveal that
TOI-836 b has a mass of M , while TOI-836 c has a mass
of M. Photometric observations show Transit Timing
Variations (TTVs) on the order of 20 minutes for TOI-836 c, although there are
no detectable TTVs for TOI-836 b. The TTVs of planet TOI-836 c may be caused by
an undetected exterior planet
