However, block environments that attempt to represent feature-rich languages, such as Python or Java, face serious usability and pedagogical challenges. How can the affordances and controls of a block be exposed, without over-complicating the block's interface and obscuring its meaning to the user? In this paper, we visually explore a number of interface mechanisms to reconfigure blocks. We outline research questions to compare and contrast the advantages and disadvantages of these mechanisms, and call on the community to pursue these trade-offs further.","PeriodicalId":424744,"journal":{"name":"2017 IEEE Blocks and Beyond Workshop (B&B)","volume":"1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130898201","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}

However, these environments offer little support when learners encounter difficulty with programming concepts themselves, especially in the absence of instructors. Textual programming environments increasingly use AI and data mining to provide intelligent, adaptive support for students, similar to human tutoring, which has been shown to improve performance and learning outcomes. In this position paper, we argue that block-based programming environments should also include these features. This paper gives an overview of promising research in intelligent support for programming and highlights the challenges and opportunities for applying this work to block-based programming.","PeriodicalId":424744,"journal":{"name":"2017 IEEE Blocks and Beyond Workshop (B&B)","volume":"24 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"132977452","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}

While some people focus on teaching conventional text-based languages like Javascript or Python, there is evidence that visual programming languages are more accessible for naive programmers. Visual programming languages fall into two broad categories: block-based, imperative programming, or flow-based, functional programming. However there have not been empirical studies to evaluate the relative merits of the two categories. This paper describes a study of hundreds of random people via Amazon Mechanical Turk attempting to program some simple problems in one or the other of two environments designed to be as similar as possible, except for the choice of paradigm.","PeriodicalId":424744,"journal":{"name":"2017 IEEE Blocks and Beyond Workshop (B&B)","volume":"18 Suppl 1 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"123563514","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}

Here I present different representations of projects that could potentially be used to identify App Inventor projects that have structural similarities to each other, e.g., projects created by users following tutorials. I compare the different representations based solely on how accurately they predict the correct tutorial from a labeled data set. The results suggest that we use both blocks and components from a project, apply TF-IDF to the counts of each feature, and measure distance or similarity in terms of a generalized Jaccard distance. This work lays the foundation for being able to find clusters of similar projects to distinguish original from unoriginal projects and to be able to filter out similar projects when trying to determine a user's skill level.","PeriodicalId":424744,"journal":{"name":"2017 IEEE Blocks and Beyond Workshop (B&B)","volume":"31 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114389477","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}

In various experiments, referenced in this paper, we observed how objects (tangibles) augmented with digital properties — that is, tangible user interface (TUI) objects — can help develop CT skills. We investigate which paradigm can be used to introduce CT skills with TUIs. By drawing on past experience, we conclude that block-oriented programming provides a suitable answer to our research questions. Furthermore, we introduce a framework for implementing block-oriented programmable objects that we believe can help end-users learn CT skills.","PeriodicalId":424744,"journal":{"name":"2017 IEEE Blocks and Beyond Workshop (B&B)","volume":"28 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-10-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"127722768","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}
