Metacognitive Experiences

This article deals with the functioning of affect and epistemic emotions, such as surprise and curiosity, in self-regulated learning (SRL). The claim is that affect plays a major role in SRL not only as an independent process that can facilitate or impede learning activities and performance but also through its interactions with cognition and metacognition. These interactions render metacognition a hot rather than a cold process. Critical cognitive states that have implications for affect and metacognition are processing fluency/disfluency, interruptions, discrepancies, or gaps in knowledge. Epistemic emotions focus on such cognitive states and are related to metacognitive experiences such as feeling of difficulty (in the case of surprise) and feeling of confidence (in the case of curiosity). Two studies exemplifying the relations between metacognitive experiences and epistemic emotions are presented. The implications of the findings for learning and SRL are discussed.

The Relationship

Viewing school administrators as learners, the purpose of this investigation was to assess the relationship between learner perceptions of differential training systems and role and performance in school administration. The findings suggest that school administrators view problem solving as an important descriptor of role and performance and that clinical training experiences may be at least as relevant or more relevant to the process of school problem solving and administration than more traditional training experiences. A perceived inverse relationship between the relative hinderance (paperwork) level of instructional media and relevance to practice was noted. School administrators saw other administrators and their professional staff as being at least as relevant to performance in a clinical setting as the training component's instructional staff.

Student Reflections

Anecdotal research is a common phenomenon in the study of distance education.  In an effort to review some of the factors that affect student satisfaction, an existing instrument was used to gauge learner perceptions of online interaction/communication, learning and performance, collaboration, hardware and software issues and the quality of support. According to some authors, use of samples of convenience and small study populations, the conclusions drawn by Yu and Brandenburg (2006) could not be generalized across differing student populations.  In an effort to create some generalizable conclusions regarding student perceptions, surveys contained some of Yu and Brandenburg’s (2006) inquiries on communication, interaction, perceptions of the instructor, course materials and the availability of student support services in online and blended courses. Questions on student demographic data were also included.  The purpose of this study is to examine some of the ideas associated with existing distance education research.  It was hypothesized that students would have had more success if 1) they had more time to interact with other students, 2) knew what the course expectations were prior to registration, c) they had access to a newer computer, and 4) they had administrative support.

It has repeatedly been show that with conventional electron microscopes very fine electron probes can be produced, therefore allowing various micro-techniques such as micro recording, X-ray microanalysis and convergent beam diffraction. In this paper the function and performance of an SIEMENS ELMISKOP 101 used as a scanning transmission microscope (STEM) is described. This mode of operation has some advantages over the conventional transmission microscopy (CTEM) especially for the observation of thick specimen, in spite of somewhat longer image recording times.Fig.1 shows schematically the ray path and the additional electronics of an ELMISKOP 101 working as a STEM. With a point-cathode, and using condensor I and the objective lens as a demagnifying system, an electron probe with a half-width ob about 25 Å and a typical current of 5.10-11 amp at 100 kV can be obtained in the back focal plane of the objective lens.

Type Detector

A cylindrical mirror analyser (CMA) has been built with a parallel recording detection system. It is being used for angular resolved electron spectroscopy (ARES) within a SEM. The CMA has been optimised for imaging applications; the inner cylinder contains a magnetically focused and scanned, 30kV, SEM electron-optical column. The CMA has a large inner radius (50.8mm) and a large collection solid angle (Ω > 1sterad). An energy resolution (ΔE/E) of 1-2% has been achieved. The design and performance of the combination SEM/CMA instrument has been described previously and the CMA and detector system has been used for low voltage electron spectroscopy. Here we discuss the use of the CMA for ARES and present some preliminary results.The CMA has been designed for an axis-to-ring focus and uses an annular type detector. This detector consists of a channel-plate/YAG/mirror assembly which is optically coupled to either a photomultiplier for spectroscopy or a TV camera for parallel detection.

Acid Anhydrides

Embedding media based upon an epoxy resin of choice and the acid anhydrides dodecenyl succinic anhydride (DDSA), nadic methyl anhydride (NMA), and catalyzed by the tertiary amine 2,4,6-Tri(dimethylaminomethyl) phenol (DMP-30) are widely used in biological electron microscopy. These media possess a viscosity character that can impair tissue infiltration, particularly if original Epon 812 is utilized as the base resin. Other resins that are considerably less viscous than Epon 812 now are available as replacements. Likewise, nonenyl succinic anhydride (NSA) and dimethylaminoethanol (DMAE) are more fluid than their counterparts DDSA and DMP- 30 commonly used in earlier formulations. This work utilizes novel epoxy and anhydride combinations in order to produce embedding media with desirable flow rate and viscosity parameters that, in turn, would allow the medium to optimally infiltrate tissues. Specifically, embeding media based on EmBed 812 or LX 112 with NSA (in place of DDSA) and DMAE (replacing DMP-30), with NMA remaining constant, are formulated and offered as alternatives for routine biological work.Individual epoxy resins (Table I) or complete embedding media (Tables II-III) were tested for flow rate and viscosity. The novel media were further examined for their ability to infilftrate tissues, polymerize, sectioning and staining character, as well as strength and stability to the electron beam and column vacuum. For physical comparisons, a volume (9 ml) of either resin or media was aspirated into a capillary viscocimeter oriented vertically. The material was then allowed to flow out freely under the influence of gravity and the flow time necessary for the volume to exit was recored (Col B,C; Tables). In addition, the volume flow rate (ml flowing/second; Col D, Tables) was measured. Viscosity (n) could then be determined by using the Hagen-Poiseville relation for laminar flow, n = c.p/Q, where c = a geometric constant from an instrument calibration with water, p = mass density, and Q = volume flow rate. Mass weight and density of the materials were determined as well (Col F,G; Tables). Infiltration schedules utilized were short (1/2 hr 1:1, 3 hrs full resin), intermediate (1/2 hr 1:1, 6 hrs full resin) , or long (1/2 hr 1:1, 6 hrs full resin) in total time. Polymerization schedules ranging from 15 hrs (overnight) through 24, 36, or 48 hrs were tested. Sections demonstrating gold interference colors were collected on unsupported 200- 300 mesh grids and stained sequentially with uranyl acetate and lead citrate.

Structure Properties

Trace constituents, which can be very loosely defined as those present at concentration levels below 1 percent, often exert influence on structure, properties, and performance far greater than what might be estimated from their proportion alone. Defining the role of trace constituents in the microstructure, or indeed even determining their location, makes great demands on the available array of microanalytical tools. These demands become increasingly more challenging as the dimensions of the volume element to be probed become smaller. For example, a cubic volume element of silicon with an edge dimension of 1 micrometer contains approximately 5×1010 atoms. High performance secondary ion mass spectrometry (SIMS) can be used to measure trace constituents to levels of hundreds of parts per billion from such a volume element (e. g., detection of at least 100 atoms to give 10% reproducibility with an overall detection efficiency of 1%, considering ionization, transmission, and counting).
