Digital content creators, such as podcasters, musicians, writers, and YouTubers, are increasingly using subscription-based crowdfunding (SBC) platforms to attract backers and obtain recurring funding from them. Unlike conventional crowdfunding, a hallmark of SBC is the recurring funding scheme structured as a creator-centered freemium model. Empowering creators to build their person brands, SBC platforms are providing creators with novel features to control the information that they share with their backers or fans or conceal from them. Based on a large-scale study on Patreon, an SBC platform, we show how creators can effectively leverage two types of information controls—earnings concealment and private postings—to build their person brands and thereby develop their backer base and fan engagement. Interestingly, we also find a reinforcing relationship in which the increases in backer base and fan engagement further stimulate creators to leverage information controls in their SBC campaigns to grow their person brands. In sum, although information controls are effective in aggregate to build person brands on SBCs, creators need to dynamically adjust the extent of use of information controls based on changes in their backer base and fan engagement.

Background and Context: The Inclusive Assessment of Computational Thinking (CT) designed for accessibility and learner variability was studied in over 50 classes in US schools (grades 3-8). Objective: The validation studies of IACT sampled thousands of students to establish IACT’s construct and concurrent validity as well as test-retest reliability. Method: IACT items for each CT practice were correlated to examine construct validity. The CT pre-measures were correlated with post-measures to examine test-retest reliability. The CT post-measures were correlated with external measures to examine concurrent validity. Findings: IACT studies showed moderate evidence of test-retest reliability and concurrent validity and low to moderate evidence of construct validity for an aggregated measure of CT, but weaker validity and reliability evidence for individual CT practices. These findings were similar for students with and without IEPs or 504s. Implications: IACT is the first CT tool for grades 3-8 that has been validated in a large-scale study among students with and without IEPs or 504s. While improvements are needed for stronger validity, it is a promising start.
