In the initial design of PyBlocks [1], Python's basic data types and lists are represented using colors, every expression block is colored according to its type, and each unfilled slot contains color indicating all valid argument types. In this paper we extend the design to include Python's most common built-in composite types (lists, tuples, dictionaries and sets) and to allow nesting of these where appropriate. Using example types from a pedagogical media computation library, we also show how further types may be supported. Together, these extensions provide almost any type novice Python programmers are likely to use.","PeriodicalId":424744,"journal":{"name":"2017 IEEE Blocks and Beyond Workshop (B&B)","volume":"71 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"133618267","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}

Smartphones afford an ideal platform for ESM study applications as devices seldom leave their users, and can automatically sense surrounding context to augment subjective survey responses. ESM studies are employed in fields such as psychology and social science where researchers are not necessarily programmers and require tools for application creation. Previous tools using web forms, text files, or flowchart paradigms are either insufficient to model the potential complexity of study protocols, or fail to provide a low threshold to entry. We demonstrate that blocks programming simultaneously lowers the barriers to creating simple study protocols, while enabling the creation of increasingly sophisticated protocols. We discuss the design of Jeeves, our blocks-based environment for ESM studies, and explain advantages that blocks afford in ESM study design.","PeriodicalId":424744,"journal":{"name":"2017 IEEE Blocks and Beyond Workshop (B&B)","volume":"266 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2017-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"124189966","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 have recently started mining this data to determine whether student performance on the programming exercises matches our assumptions about the difficulty of the individual exercises. Various analytic techniques, such as linear regression, are used to identify those features that are most determinative of problem difficulty. Our analysis supports that the number of abstractions may be a useful predictor for the difficulty (defined for our data set as the average number of attempts) in solving Quizly exercises. However, there are other not so easily quantifiable factors that also affect a problem's difficulty.","PeriodicalId":424744,"journal":{"name":"2017 IEEE Blocks and Beyond Workshop (B&B)","volume":"42 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":"123857554","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 investigate the use of procedures in MIT App Inventor, a web-based blocks programming environment for creating Android mobile apps. We explore how procedures are used “in the wild” by examining two datasets of App Inventor projects: all projects of ten thousand randomly chosen users and all projects of all prolific users (those users with 20 or more projects). Our data analysis indicates that procedural abstraction is a concept that is learned over time by some App Inventor users, but it is used relatively infrequently, and features like parameters and returning values are used even more rarely. Procedures are most frequently called only once, indicating that they are often used to organize code rather than to reuse it. Surprisingly, 10% of declared procedures are never called, suggesting that this situation should be flagged by the environment.","PeriodicalId":424744,"journal":{"name":"2017 IEEE Blocks and Beyond Workshop (B&B)","volume":"10 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":"123147306","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 addition to feedback based on run-time and output checking, we are particularly interested in immediate feedback: corrective guidance given as the program is being constructed. Immediate feedback is a natural extension of the block-based language philosophy. Block-based languages prevent by design certain types of mistakes in all cases. Immediate feedback guides against, without fully preventing, problem-specific mistakes (i.e., constructions that are erroneous in only some cases). A feedback specification contains a block pattern and a set of actions that can be taken whenever the corresponding pattern is present or absent in the student's block program for a given problem. The paper illustrates the language through several examples derived from misconceptions found in the block-based programs of students taking a university-level Computational Thinking class. The feasibility of the proposed approach is shown by the translation of a specification using an evolving programmatic interface in BlockPy, a dual block/text programming environment for a subset of Python.","PeriodicalId":424744,"journal":{"name":"2017 IEEE Blocks and Beyond Workshop (B&B)","volume":"50 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":"115617416","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 this paper, we explore the potential of using this same approach in a very different programming context: industrial robotics. Using a customized language built with the Blockly library, we created a block-based interface for programming a one-armed industrial robot. This paper presents a block-based robot programming language called Robot Blockly, focusing on how the various affordances of block-based programming were utilized to make the challenge of robot programming more accessible. We also present results from a small-scale study showing adults with no prior programming experience successfully programming a virtual robot to accomplish a pick and place task.

To alleviate this problem, we propose a novel pedagogy uniting logical reasoning with proofs of program correctness along with a proof assistant, ORC2A, that helps students author proofs in this domain. One of the defining features of ORC2A is that it has a blocks-based surface language of proof to reduce friction when adopting the tool in the classroom. We report on the current progress on ORC2A, in particular, its blocks-based interface, current design consideration, and our plans for evaluating the system.","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":"130010153","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}
