A recent “third wave” of neural network (NN) approaches now delivers state-of-the-art performance in many machine learning tasks, spanning speech recognition, computer vision, and natural language processing. Because these modern NNs often comprise multiple interconnected layers, work in this area is often referred to as deep learning. Recent years have witnessed an explosive growth of research into NN-based approaches to information retrieval (IR). A significant body of work has now been created. In this paper, we survey the current landscape of Neural IR research, paying special attention to the use of learned distributed representations of textual units. We highlight the successes of neural IR thus far, catalog obstacles to its wider adoption, and suggest potentially promising directions for future research. 相似文献
Since its inception 30 years ago, the then Department of Engineering Science, Institut Teknologi MARA (ITM) was given the responsibility of preparing all the students in the first year engineering programmes by giving enough knowledge in basic science and mathematics. The nation's vision to become a fully‐industrialised economy by the year 2020 required all institutes of higher learning (IHLs) in Malaysia to increase their intake of students in the science and technology courses, especially in engineering. However, at the upper secondary education level, students have the freedom to choose between the science‐based or non‐science combination of subjects. This has led to a dearth of science‐based students enrolling in IHLs. Because ITM believes that it is possible to educate individuals from various backgrounds, the engineering courses are open to students with a variety of academic qualifications. Special bridging courses were designed and created for such students since late 1996. The success or failure of the new courses can be assessed after the students have gone through the proper first year engineering courses which consist of Mathematics, Physics and Chemistry. This paper reports on a pilot study on the pioneer groups of students with variable entry qualifications to assess the effectiveness of the courses. The study involved the analysis of the students’ examination results as a performance indicator, and it was found that the bridging programme for non‐science students needed to be redesigned. It is also proposed that to improve the quality of the programme, and hence students’ performance, a regular review be conducted, student support activities be continued and to expand the use of self‐study materials. 相似文献
It is generally known that the general goals of universities are to produce high-quality graduates for the job market, to
continuously advance the frontier of knowledge in all the disciplines, and ultimately to advance human civilization. There
can, however, be numerous specific goals which differ from one university to the other. Whatever it is, in order to achieve
the desired goals, universities need to design a realistic strategic development plan, which must include, among others, the
important logistical components and factors of university development. In Malaysia, little is known about university development
planning process as a subject area. Annual reports and calendars published by universities do not provide sufficient information
about the elements and aspects of high priorities in their strategic development plan. As such, we decided to conduct a study
on eleven (11) foremost public universities in Malaysia—a country with a centralized education system—in order to examine
the goals, components, and factors considered by university top-management in planning university development. We administered
a checklist to 296 respondents, comprising deputy vice-chancellors or deputy rectors, registrars, deans, and directors. The
checklist required the respondents to rate the consideration level on a scale of 1 (least considered) to 5 (highly considered)
for each of the items on goals, components, and factors. This article reports the main findings of our study. Among other
things, the most obvious result revealed by the study was that universities were very concerned with the relevancy of academic
programs offered and their performance in research. It was rather surprising, however, that the top-management of public universities
in Malaysia placed the goal of providing quality infrastructure and facilities at the lowest ranking. Also, this study revealed
that the government, as a factor, exerted its prominence only in terms of university budget and research grants and the execution
of some policies of national interest, but university expansion and development was largely driven by the university organization
itself, i.e., on where, what, and how it wants to expand and grow. In this regard, public universities in Malaysia still enjoy
a large degree of academic autonomy and a strong support by the government. 相似文献
Despite considerable research in advanced countries on public perceptions of and attitudes to modern biotechnology, limited effort has been geared towards developing a structural model of public attitudes to modern biotechnology. The purpose of this paper is to identify the relevant factors influencing public attitudes towards genetically modified (GM) soybean, and to analyze the relationship between all the attitudinal factors. A survey was carried out on 1,017 respondents from various stakeholder groups in the Klang Valley region. Results of the survey have confirmed that attitudes towards complex issues such as biotechnology should be seen as a multifaceted process. The most important factors predicting support for GM soybean are the specific application-linked perceptions about the benefits, acceptance of risk and moral concern while risk and familiarity are significant predictors of benefit and risk acceptance. Attitudes towards GM soybean are also predicted by several general classes of attitude. 相似文献
Background: Elementary Science Education is struggling with multiple challenges. National and State test results confirm the need for deeper understanding in elementary science education. Moreover, national policy statements and researchers call for increased exposure to engineering and technology in elementary science education. The basic motivation of this study is to suggest a solution to both improving elementary science education and increasing exposure to engineering and technology in it.
Purpose/Hypothesis: This mixed-method study examined the impact of an engineering design-based curriculum compared to an inquiry-based curriculum on fifth graders’ content learning of simple machines. We hypothesize that the LEGO-engineering design unit is as successful as the inquiry-based unit in terms of students’ science content learning of simple machines.
Design/Method: We used a mixed-methods approach to investigate our research questions; we compared the control and the experimental groups’ scores from the tests and interviews by using Analysis of Covariance (ANCOVA) and compared each group’s pre- and post-scores by using paired t-tests.
Results: Our findings from the paired t-tests show that both the experimental and comparison groups significantly improved their scores from the pre-test to post-test on the multiple-choice, open-ended, and interview items. Moreover, ANCOVA results show that students in the experimental group, who learned simple machines with the design-based unit, performed significantly better on the interview questions.
Conclusions: Our analyses revealed that the design-based Design a people mover: Simple machines unit was, if not better, as successful as the inquiry-based FOSS Levers and pulleys unit in terms of students’ science content learning. 相似文献
This article discusses the views of Turkish and British novice teachers on pedagogy and pedagogical relationships with school students when confronted with the pedagogical practices of the ‘Other’ in particular policy contexts. Experiences of those practices were gained by novice teachers during an exchange visit for British and Turkish university students in the period 2008–2009. Data was collected through questionnaires and focus group interviews. Findings suggest that Turkish and British novice teachers initially constructed the ‘Other’ as very different from themselves. The views of members of both groups were heavily influenced by the cultural contexts in which they trained and worked. British novice teachers tended to take as axiomatic constructivist and inclusive approaches to pedagogy and the relevance to successful pedagogy of listening to students’ voices. Turkish novice teachers questioned both, many seeing control and dissemination of knowledge as central to pedagogy and student teacher relationships. 相似文献
The DIIA (Diploma in Investment Analysis) students from the FBM (Faculty of Business Management) were required to undertake several MOF (Mathematic of Finance) courses. The passing rates for all of the MOF courses were good except for one course. There are many factors for this low passing rate phenomenon for this particular MOF course. One of the factors is mathematics anxiety as suggested by Richardson in 1971. As a result, this paper is carried out in order to measure the undergraduates' level of mathematics anxiety in general and between genders in this one particular course. The outcome is expected to fill in the gap as study of anxiety in MOF is still lacking. A 30-item MARS (Mathematics Anxiety Rating Scale) is adapted and used in this study, because this course is predominant by complex computations. The Ss (samples) of the study are 119 students who undertook this MOF course during the study semester of December 2008 to April 2009 in UiTM (Universiti Teknologi MARA). It is expected that the findings will show that the Ss have a considerably high mean for mathematics anxiety; and female students have a higher mean of mathematics anxiety as compared to their male counterparts. The study confirms the expectation of the researchers. In terms of the final and overall results, it was expected that the passing percentage be dominated by the male students. However, at the end of the study, the overall performance of the female students was much better compared to their male counterparts. 相似文献
Adult learners are returning to college in increasing numbers. The Marywood University Library has seen an influx, particularly in the university's Master of Social Work program, where many adult learners are reentering school after years of absence. Reaching out to this user group, the library initiated a personal librarian service through a Course Management System, a familiar online environment for these students. A survey was conducted to determine whether library help delivered in this way is favored among adult learners. 相似文献
The use of gamification to enhance learning in education has been well documented. However, little is known about whether gamification can impact supply chain management knowledge and behaviors among healthcare professionals. In this study, we tested the effectiveness of a simulation app (ShipShape) designed and developed to gamify the fundamental concepts of supply chain management. We field tested the effectiveness of the app to impact knowledge gain and supply chain practice by asking healthcare professionals to use the app in their day-to-day operations. We collected longitudinal data spanning the period before and after the introduction of the app. The analysis and results of different types of data collected provide support for the positive impact of the app on both supply chain knowledge and practice among healthcare professionals. 相似文献
