However, teaching novices programming has long been considered a big challenge by computer science educators as manifested by the observation that first-year programming topics tend to have a higher failure rate than other first-year topics. Existing studies have discovered that lack of engagement in learning programming is a key determinant of a student's poor performance. Therefore, it is beneficial to perceive a student's lack of engagement so that appropriate actions can be taken ahead of time. However, first year topics especially programming topics usually have very large enrolments, making it hard for a lecturer to keep track of each individual student's engagement level. As learning management systems (LMS) have been widely adopted by universities, in this paper we suggest using a student's voluntary participation in a programming topic's discussion forum provided by LMS as an engagement indicator so that the lecturer can constantly monitor and re-engage those who present low or no engagement. This recommendation is based on an empirical study of a first-year programming topic that reveals a positive correlation between one's voluntary participation in peer interaction through the topic's discussion forum and one's learning outcome in the topic.","PeriodicalId":309823,"journal":{"name":"Proceedings of the 28th Australian Conference on Computer-Human Interaction","volume":"29 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132884035","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}

We explore this possibility for the retrieval of news broadcasts in Danish. An average of 84% of the words in the broadcasts was recognized. Most of the unrecognized words were compounds, names, and other words that appear of value to retrieval. Thus, the set of words describing a broadcast has to be expanded to compensate for the recognition errors. We discuss doing this by exploiting the alternative matches from the speech recognizer and by extracting words from a related corpus.","PeriodicalId":309823,"journal":{"name":"Proceedings of the 28th Australian Conference on Computer-Human Interaction","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133249055","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}

This paper examined literature and known projects in Human-Computer Interaction (HCI) and related fields that aim to facilitate children's interaction with the natural world through technology. A thematic analysis was then undertaken in order to identify the different approaches to connecting children with nature through technology. We identified three major types of technology use, instructional, exploratory and contributory: (1) Instructional technology to enhance and enable structured science curriculum activities in outdoor environments; (2) Exploratory technology to encourage children to explore outdoors in nature; (3) Contributory technology to engage children in contributing to citizen science activities. We discuss ways to deepen and extend the scope of HCI research for environment, in order to entice and engage children to care about the physical environment and nature on its own terms, developing lasting connections to and knowledge about their natural environment.","PeriodicalId":309823,"journal":{"name":"Proceedings of the 28th Australian Conference on Computer-Human Interaction","volume":"36 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"117044810","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 participatory action research process allowed our Aboriginal partners to embed their own culture in the games, leading to a product that supported their goals and aspirations for language renewal. This collaboration has not only provided a way to sustain their language, but also added capacity to their community in ICT development.

Human Computer Interaction (HCI) as a progressive field of research, has opened up alternatives to the traditional interaction techniques. Embedded Infrared (IR) sensors, Accelerometers and RGBD cameras have become common inputs for devices to recognize gestures and body movements. These sensors are vision based and as a result the devices that incorporate them will be reliant on presence of light. Ultrasonic sensors on the other hand do not suffer this limitation as they utilize properties of sound waves. These sensors however, have been mainly used for distance detection and not with HCI devices. This paper presents our approach in developing a multi-dimensional interaction input method and tool Ultrasonic Gesture-based Interaction (UGI) that utilizes ultrasonic sensors. We demonstrate how these sensors can detect object movements and recognize gestures. We present our approach in building the device and demonstrate sample interactions with it. We have also conducted a user study to evaluate our tool and its distance and micro gesture detection accuracy. This paper reports these results and outlines our future work in the area.","PeriodicalId":309823,"journal":{"name":"Proceedings of the 28th Australian Conference on Computer-Human Interaction","volume":"6 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127413099","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}

App reviews---some helpful, others irrelevant---can be analysed for feedback on this user experience. However, few studies have specifically examined the helpfulness of app reviews. In this paper, we surveyed users and developers to rate 167 reviews for helpfulness, obtaining a total of 2,558 helpfulness ratings captured on a 5 point Likert scale. We found only slight agreement (nominal Krippendorff's alpha = 0.039) between participants on the helpfulness of reviews. Differences between reviews become evident when we summarise all the helpfulness ratings per review. We conclude that the disagreement among users limits the potential of mobile app review recommender systems.","PeriodicalId":309823,"journal":{"name":"Proceedings of the 28th Australian Conference on Computer-Human Interaction","volume":"102 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2016-11-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132391528","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}
