Students (n=34) took three tests in the following order: (1) mathematics vocabulary, (2) WRAT Computation, and (3) GMRT Vocabulary. Mathematics vocabulary results revealed that the mathematics vocabulary test was highly reliable. Based on students’ scores in all tests, the correlation between mathematics vocabulary knowledge and general vocabulary knowledge as well as the relationship between mathematics vocabulary and mathematics computation were strong. However, there was no significant association between mathematics computation and general vocabulary knowledge. Mathematics vocabulary knowledge was a mediator between the two.","PeriodicalId":7397,"journal":{"name":"ACM SIGCHI Bull.","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2006-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74773599","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

{"title":"Resurrection & penance","authors":"Richard I. Anderson","doi":"10.1145/360405.360417","DOIUrl":"https://doi.org/10.1145/360405.360417","url":null,"abstract":"The process of starting a CHI local SIC can appear daunting. The process of running a CHI local SIC ongoing-i.e., keeping things going and going-probably appears even more daunting; indeed, there have been a few cases of CHI local SIGs becoming dormant. Several previous columns have addressed the topics of starting a local SIC and keeping it going; for example, the January 99 column tells the tale of \"Starting a S IGCHI Local Group in the Netherlands\"; the April 97 column, \"The Social Design of a Local SIC,\" describes key elements of the design of a sustained community; the January '97 column is about \"Ensuring a Local SIG's Future: Fitting Into & Creating a Culture\"; and the April 99 column provides advice regarding the many \"Challenges Facing CHI Local SIGs.\" But, if a CHI local SIG has stopped functioning, how do you get it going again? What Leads to Local SIC Dormancy? The primary reason a few local SIGs have died appears to be the disappearance of the one key energetic leader-often the one who got the local SIC going in the first place. CHI-Atlanta (Georgia) stopped functioning a few years ago when its founder moved from the area. Lone Star CHI (Dallas / Ft. Worth, Texas) became dormant more recently when its leader moved from the area, and LA SIGCHI (Los Angeles, California) has suffered multiple periods of dormancy when different leaders moved away. CapCHI (Ottawa, Canada) became dormant in 1997 when the person who ran the chapter single-handedly for a long time burned out. After about 2 years of regular meetings, SwissCHI experienced an \"unplanned intermission\" of several months during 1998, because no one wanted to take the lead in setting up new meetings. A CHI-Austin (Texas) \"pause\" occurred for similar reasons. This is a problem local SIGs must try to avoid. It is very important to involve others who can play key leadership roles; such involvement readies others to take over if necessary and reduces the chance of leadership burnout. But, sometimes involving others can be difficult. Indeed, many local SIGs report difficulty finding volunteers and integrating those they do find within the leadership core. Other developments can lead to dor-mancy. Dormancy struck NUCHI (Northern Utah) and TriCHI (Research Triangle Park, North Caro-lina) when significant changes in the makeup of the industrial landscape in those areas greatly lowered the number of people interested in a local community. …","PeriodicalId":7397,"journal":{"name":"ACM SIGCHI Bull.","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2000-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87317196","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

End-User Challenge: Speech provides a new and larger set of capabilities to the user, and can improve the quality of the user interface over touch-tone interactions. However, speaking to systems is unfamiliar to users, and each system is different requiring users to learn how to use each one individually. A greater degree of predictability in the interface would likely reduce the end-user's learning curve, speeding adoption and increasing the user's comfort level. Touch-tone systems have not had the benefit of interface standards, and user confusion about the meaning/function of certain \"keys\" on the keypad is not uncommon.","PeriodicalId":7397,"journal":{"name":"ACM SIGCHI Bull.","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2000-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87175071","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The gap between welleducated and poorly educated is also increasing. Today's 90minute discussion by government, business, and community leaders (see list below) tried to draw attention to the issues, describe efforts to deal with it, and promote new initiatives. Secretary Daley promised annual reports on progress and needs.

A universal command is one that is available to the caller at all times. Example universals from some currently deployed systems include \"help\" in order to get additional instruction relevant to the current state of the call, and \"repeat\" to hear the most recent prompt again. Universal commands provide the caller with consistency throughout an application. They typically provide functions a caller can fall back on any time they are having problems, increasing the ease of use of systems.","PeriodicalId":7397,"journal":{"name":"ACM SIGCHI Bull.","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2000-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"73244989","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

He asked a lot of questions to our adults and kids who work together in a team. But the funny thing is we weren' t sure he really understood our answers to his questions. All too often this seems to happen, because most people make certain assumptions about how adults and kids can work together to create new technologies. Many people assume kids can be technology testers. Some people even think kids can help in the brainstorming process every once in a while. But few people quite believe that adults and kids can be on-going partners in designing new technology. This is what we strive for here in Maryland.","PeriodicalId":7397,"journal":{"name":"ACM SIGCHI Bull.","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2000-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"83071283","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

A laser pointer used by the instructor emulates mouse actions on a computer projection screen. An inexpensive video camera sends each projected frame to a video capture card in the computer; our software detects the bright laser spot, moves a screen cursor, and performs other mouse operations according to user actions. The system frees the instructor to move about the classroom as he/she controls the presentation. Other software allows students, from their laptop computers, to request control of the main computer's mouse and keyboard over a local network. This facilitates student interaction with the main computer's screen to perform tasks like: go to specific parts of the presentation; enter text; annotate diagrams; run programs. Both systems can help increase interactivity between instructor and students in a large classroom environment. Technical details are given in this paper.","PeriodicalId":7397,"journal":{"name":"ACM SIGCHI Bull.","volume":null,"pages":null},"PeriodicalIF":0.0,"publicationDate":"2000-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"81683259","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
