The study made an exploration of the feedback quality of an Automated Writing Evaluation system (AWE) Pigai, which has been widely applied in English teaching and learning in China. The study not only focused on the diagnostic precision of the feedback but also investigated the students’ perceptions of the feedback use in their daily writing practices. Taking 104 university students’ final exam essays as the research materials, the paired sample t-test was conducted to compare the mean number of errors identified by Pigai and professional teachers. It was found that Pigai feedback could not so well diagnose the essays as the human feedback given by the experienced teachers, however, it was quite competent in identifying lexical errors. The analysis of students’ perceptions indicated that most students thought Pigai feedback was multi-functional, but it was inadequate in identifying the collocation errors and giving suggestions in syntactic use. The implications and limitations of the study were discussed at the end of the paper.

This research seeks to examine the effectiveness of learning tactical and technical approach to the learning outcomes of football skills. Results of this study are expected to be used as an alternative solution in order to develop the quality of learning football. The method used in this study is the experimental method to the design of post-only design. The population in this study were students of class XI SMA Labschool son UPI Bandung as many as 60 students. The sampling technique using purposive sampling technique.When the study is over 2 months, the number of 18 treatment sessions, with a frequency of 1 week 3 times. Author chosen instrument is a test of football skill and playing ability test (GPAI) for high school students football skills tests (test start and end of the football skills) there are four authors use the test passing and stoping, heading, dribbling and shooting and playing ability test (GPAI). Based on the analysis, it can be concluded that: (1) there is a significant effect of learning tactical approach to the learning outcomes of football skills. (2) There is a significant effect of technical learning approach to the learning outcomes of football skills. (3) There are differences in the effect of tactical and technical learning approach towards learning outcomes football skills, but more tactical approach a significant impact on learning outcomes of football skills than technical learning approach.Keywords: learning approach tactical, technical learning approach, results learning skills football.

This study was a research and development used ADDIE model aimed to produce mathematics textbook for 8th-grade students by applying five principles of the Realistic Mathematics Education (RME) approach, included: phenomenological exploration, bridging by vertical instruments, self-reliance with students own constructions and productions, interactivity, and intertwining. The subject in this study involved 30 students' junior high school in Yogyakarta. The qualities of the developed textbook refer to three criteria, namely validity, practicality, and effectiveness. Supporting instruments used to examine three criteria for the quality of the textbook were validation sheets, assessment sheets for teachers and students, and students' mathematical communication ability test. The textbook meets the criteria of validity, practicality, and effectiveness if at least "good" from the results of validator assessments, the results analysis from teachers and student assessments, and at least 75% of the students' mathematical communication ability test results. Based on the results of this study, the developed textbook has met the criteria of validity (very good), practicality (very good by the teacher and good by students), and effectiveness (good for 86.67%). Therefore, developing textbooks is suitable to use as an alternative to enhance the students' mathematical communication ability.

This study aims to analyze argument-counterargument structure of English argumentative essays written by Chinese EFL university students, based on the adapted Toulmin’s (2003) model of the argument structure constituting four elements (i.e. claim, data, counterargument and rebuttal). It also measures whether there is a correlation between the use of counterargument structure and the participants’ overall essay quality assessed by an online AWE (Automated Writing Evaluation) program. Three hundred and ninety students with various majors in a Chinese university submitted their argumentative essays in English online. The results demonstrated that half of the participants developed a one-sided model of argumentation while the other half of them used argument-counterargument structure in their essays. The participants’ use of counterarguments affected the overall quality of their essays. Pedagogical implications of these findings are also discussed.

Grammatical Structures

Syntactic complexity is considered to be an important device for assessing the quality of writing in a second language (L2), as it indicates the diversity and complexity of production units or grammatical structures. This paper studies the development of Chinese college students’ syntactic complexity in essay writing by using an Automatic Writing Evaluation (AWE) tool, the Pigai system (www.pigai.org, which has been most widely used in China in the last ten years). The data analysis showed that the students’ syntactic competences in their final drafts outperformed that in their first drafts in three aspects: length of production unit, amount of subordination, and amount of coordination.

Valid evaluations of automated writing evaluation (AWE) design, development, and implementation should integrate the learners’ perspective in order to ensure the attainment of desired outcomes. This paper explores the learner fit quality of the Research Writing Tutor (RWT), an emerging AWE tool tested with L2 writers at an early stage of its development. Employing a mixed-methods approach, the authors sought to answer questions regarding the nature of learners’ interactional modifications with RWT and their perceptions of appropriateness of its feedback about the communicative effectiveness of research article Introductions discourse. The findings reveal that RWT’s move, step, and sentence-level feedback provides various opportunities for learners to engage with the revision task at a useful level of difficulty and to stimulate interaction appropriate to their individual characteristics. The authors also discuss insights about usefulness, user-friendliness, and trust as important concepts inherent to appropriateness.

Definition Of

During the past investigations of immunoferritin localization of intracellular antigens in ultrathin frozen sections, we found that the degree of negative staining required to delineate u1trastructural details was often too dense for the recognition of ferritin particles. The quality of positive staining of ultrathin frozen sections, on the other hand, has generally been far inferior to that attainable in conventional plastic embedded sections, particularly in the definition of membranes. As we discussed before, a main cause of this difficulty seemed to be the vulnerability of frozen sections to the damaging effects of air-water surface tension at the time of drying of the sections.Indeed, we found that the quality of positive staining is greatly improved when positively stained frozen sections are protected against the effects of surface tension by embedding them in thin layers of mechanically stable materials at the time of drying (unpublished).

Exposure Process

Most production electron beam lithography systems can pattern minimum features a few tenths of a micron across. Linewidth in these systems is usually limited by the quality of the exposing beam and by electron scattering in the resist and substrate. By using a smaller spot along with exposure techniques that minimize scattering and its effects, laboratory e-beam lithography systems can now make features hundredths of a micron wide on standard substrate material. This talk will outline sane of these high- resolution e-beam lithography techniques.We first consider parameters of the exposure process that limit resolution in organic resists. For concreteness suppose that we have a “positive” resist in which exposing electrons break bonds in the resist molecules thus increasing the exposed resist's solubility in a developer. Ihe attainable resolution is obviously limited by the overall width of the exposing beam, but the spatial distribution of the beam intensity, the beam “profile” , also contributes to the resolution. Depending on the local electron dose, more or less resist bonds are broken resulting in slower or faster dissolution in the developer.
