The search interface is made of three sections: Search, Explore, and Results. These are described in detail below.
You may start searching either from the Search section or from the Explore section.
Search
This section shows your current search criteria and allows you to submit keywords to search in the bibliography.
Each new submission adds the entered keywords to the list of search criteria.
To start a new search instead of adding keywords to the current search, use the Reset search button, then enter your new keywords.
To replace an already submitted keyword, first remove it by unchecking its checkbox, then submit a new keyword.
You may control the extent of your search by selecting where to search. The options are:
Everywhere: Search your keywords in all bibliographic record fields and in the text content of the available documents.
In authors or contributors: Search your keywords in author or contributor names.
In titles: Search your keywords in titles.
In publication years: Search a specific publication year (you may use the OR operator with your keywords to find records having different publication years, e.g., 2020 OR 2021).
In all fields: Search your keywords in all bibliographic record fields.
In documents: Search your keywords in the text content of the available documents.
You may use boolean operators with your keywords. For instance:
AND: Finds entries that contain all specified terms. This is the default relation between terms when no operator is specified, e.g., a b is the same as a AND b.
OR: Finds entries that contain any of the specified terms, e.g., a OR b.
NOT: Excludes entries that contain the specified terms, e.g., NOT a.
Boolean operators must be entered in UPPERCASE.
You may use logical groupings (with parentheses) to eliminate ambiguities when using multiple boolean operators, e.g., (a OR b) AND c.
You may require exact sequences of words (with double quotes), e.g., "a b c". The default difference between word positions is 1, meaning that an entry will match if it contains the words next to each other, but a different maximum distance may be specified (with the tilde character), e.g., "web search"~2 allows up to 1 word between web and search, meaning it could match web site search as well as web search.
You may specify that some words are more important than others (with the caret), e.g., faceted^2 search browsing^0.5 specifies that faceted is twice as important as search when computing the relevance score of the results, while browsing is half as important. Such term boosting may be applied to a logical grouping, e.g., (a b)^3 c.
Keyword search is case-insentitive, accents are folded, and punctuation is ignored.
Stemming is performed on terms from most text fields, e.g., title, abstract, notes. Words are thus reduced to their root form, saving you from having to specify all variants of a word when searching, e.g., terms such as search, searches, and searching all produce the same results. Stemming is not applied to text in name fields, e.g., authors/contributors, publisher, publication.
Explore
This section allows you to explore categories associated with the references.
Categories can be used to filter your search. Check a category to add it to your search criteria and narrow your search. Your search results will then only show entries that are associated with that category.
Uncheck a category to remove it from your search criteria and broaden your search results.
The numbers shown next to the categories indicate how many entries are associated with each category in the current set of results. Those numbers will vary based on your search criteria to always describe the current set of results. Likewise, categories and whole facets will disappear when the result set has no entry associated to them.
An arrow icon () appearing next to a category indicates that subcategories are available. You may press it to expand a list of more specific categories. You may press it again later to collapse the list. Expanding or collapsing subcategories will not change your current search; this allows you to quickly explore a hierarchy of categories if desired.
Results
This section shows the search results. When no search criteria has been given, it shows the full content of the bibliography (up to 20 entries per page).
Each entry of the results list is a link to its full bibliographic record. From the bibliographic record view, you may continue exploring the search results by going to previous or following records in your search results, or you may return to the list of results.
Additional links, such as Read document or View on [website name], may appear under a result. These give you quick access to the resource. Those links will also be available in the full bibliographic record.
The Abstracts button lets you toggle the display of abstracts within the list of search results. Enabling abstracts, however, will have no effect on results for which no abstract is available.
Various options are provided to let you sort the search results. One of them is the Relevance option, which ranks the results from most relevant to least relevant. The score used for ranking takes into account word frequencies as well as the fields where they appear. For instance, if a search term occurs frequently in an entry or is one of very few terms used in that entry, that entry will probably rank higher than another where the search term occurs less frequently or where lots of other words also occur. Likewise, a search term will have more effect on the scores if it is rare in the whole bibliography than if it is very common. Also, if a search term appears in, e.g., the title of an entry, it will have more effect on the score of that entry than if it appeared in a less important field such as the abstract.
The Relevance sort is only available after keywords have been submitted using the Search section.
Categories selected in the Explore section have no effect on the relevance score. Their only effect is to filter the list of results.
This study explores the influence of digital game-based learning on the English learning outcomes and learning motivation of first-grade primary school students in a private girls' school in Macau. The researcher used the Wordwall digital game platform as the medium and conducted teaching experiments using the quasi-experimental research method. Two classes were divided into the experimental group (n=24) and the control group (n=21) according to the convenient sampling method. The digital game-based learning method was integrated into the teaching materials and school-based self-compiled content. The experimental group implemented the digital game-based learning method for 8 weeks. Using the Wordwall game platform once a week, and 20 minutes each time, the control group maintained the traditional didactic teaching method. The research tools included a self-compiled learning effectiveness test and a learning motivation scale. The total score of the learning effectiveness test was 40 points, and the total score of the learning motivation scale was 120 points. Data analysis was conducted using paired sample t-tests and independent sample t-tests.
The research results show that: (1) The score of the experimental group in the post-test of learning outcomes was slightly higher than the control group, indicating that the digital game-based learning method has a positive impact on students' learning outcomes. (2) In terms of learning motivation, the post-test score of the experimental group was slightly higher than the pre-test score, while the control group showed the opposite, indicating that the digital game-based learning method has a positive impact on students' learning motivation.
According to the research results, it is suggested that the following can be revised in future studies including (1) expand the scope of research samples and objects, (2) extend the time of teaching experiments, (3) adopt diversified assessment tools, (4) consider teaching environment and teacher factors, (5) conduct learning analysis for individual differences, and (6) carry out cross-disciplinary integration and teaching mode innovation. Exploring the impact of digital game-based learning on students' learning outcomes and motivation from more diverse perspectives.
本研究旨在探討數位遊戲式學習對澳門某私立女校小學一年級學生的英語學習成效和學習動機之影響。研究者以Wordwall數位遊戲平台為媒介，並透過準實驗研究法來進行教學實驗，將兩個班級按方便取樣的方式分為實驗組（n=24）和控制組（n=21），把數位遊戲式學習法融入教材和校本自編內容當中，實驗組實施為期8週的數位遊戲式學習法，每週使用Wordwall遊戲平台1次，每次使用時間為20分鐘；控制組則維持傳統講述法教學，研究工具包含自編的學習成效測驗卷和學習動機量表，學習成效測驗卷的總分為40分，學習動機量表的總分為120分，並以配對樣本t檢定與獨立樣本t檢定進行數據分析。 研究結果顯示：（1）在學習成效方面，實驗組的後測得分稍微高於控制組，顯示數位遊戲式學習法對學生的學習成效具正面影響。（2）在學習動機方面，實驗組的後測分數稍微高於前測分數，控制組則相反，顯示數位遊戲式學習法對學生的學習動機具正面影響。 根據研究結果顯示，建議未來的研究可擴大研究樣本和對象範圍、延長教學實驗的時間、採用多元化的評量工具、考慮教學環境和教師因素、針對個別化差異進行學習分析、進行跨領域整合和教學模式創新，以更多元的角度探討數位遊戲式學習對學生學習成效和學習動機的影響。
