Constructivist Practices

Developing Business Intelligence (BI) has been a top priority for enterprise executives in recent years. To meet these demands, universities need to prepare students to work with BI in enterprise settings. In this study, we considered a business simulator that offers students opportunities to apply BI and make top-management decisions in a system used by real-world professionals. The simulation-based instruction can be effective only if students are not discouraged by the difficulty of using the BI computer system and comprehending the complex BI subjects. Constructivist practices embedded in the business simulation are investigated to understand their potentials for helping the students to overcome the perceived difficulty. Consequently, it would enable instructors to more efficiently use the simulator by providing insights on its pedagogical practices. Our findings showed that the constructivist practices such as collaboration and subject integration positively influence active learning and meaningful learning respectively. In turn, both active learning and meaningful learning positively influence business intelligence motivational behavior. These findings can be further used to develop a robust learning environment in BI classes.

Backstepping Algorithm

Pipelines are a nonlinear and complex component to transfer fluid or gas from one place to another. From economic and environmental points of view, the safety of transmission lines is incredibly important. Furthermore, condition monitoring and effective data analysis are important to leak detection and localization in pipelines. Thus, an effective technique for leak detection and localization is presented in this study. The proposed scheme has four main steps. First, the learning autoregressive technique is selected to approximate the flow signal under normal conditions and extract the mathematical state-space formulation with uncertainty estimations using a combination of robust autoregressive and support vector regression techniques. In the next step, the intelligence-based learning observer is designed using a combination of the robust learning backstepping method and a fuzzy-based technique. The learning backstepping algorithm is the main part of the algorithm that determines the leak estimation. After estimating the signals, in the third step, their classification is performed by the support vector machine algorithm. Finally, to find the size and position of the leak, the multivariable backstepping algorithm is recommended. The effectiveness of the proposed learning control algorithm is analyzed using both experimental and simulation setups.

University Spanish courses designed specifically for heritage language learners (HLLs) are becoming more common, and researchers have indicated that empirical research is needed to evaluate their effectiveness. This longitudinal study investigates the writing development of 24 HLLs as a result of instruction over the course of the semester. Nine were enrolled in a heritage-only section of a Spanish composition course, and the remainder were from mixed HL/L2 sections of the same course. Both section types were taught online. The major assignments the students produced were two 500-word essays, and students also completed bi-weekly forum posts. We examined the development of lexical density, sophistication, and diversity as well as syntactic complexity and accuracy by comparing each student’s first and final essay and forum posts. Findings indicate that there were significant differences between the scores received on the forum posts in comparison to the essays. However, there were no significant developmental differences in terms of group. Implications, avenues for future research, and pedagogical suggestions are discussed.

A system that builds and maintains a dynamic map for a mobile robot is presented. A learning rule associated to each observed landmark is used to compute its robustness. The position of the robot during map construction is estimated by combining sensor readings, motion commands, and the current map state by means of an Extended Kalman Filter. The combination of landmark strength validation and Kalman filtering for map updating and robot position estimation allows for robust learning of moderately dynamic indoor environments.

Abstract Because of limited language input, different dominant languages, and learners’ differing backgrounds, the acquisition of heritage languages is distinguished from the acquisition of L1 and L2. Few studies of Chinese as a Heritage Language (CHL) have explored whether students can acquire native-like sociolinguistic competence and language-specific variables with educational input. Based on a sociolinguistic variationist perspective, this study investigates the acquisition of variation between null and overt subject personal pronouns (SPP s) by heritage learners in an undergraduate-level Mandarin program. A total of 11,970 tokens were collected through classroom observation, sociolinguistic interviews, and narratives. Measuring mixed-effects logistic regression with Rbrul (Johnson, 2009), results show that the overall usage pattern of SPP s by CHL students largely resembled that in the input provided by the language program. Results also demonstrate that linguistic constraints including coreference, person and number, and verb type, and social factors such as discourse context, first languages, course level, and age of arrival had a significant effect on SPP expression by CHL learners. Implications for CHL development and variationist studies in heritage languages are discussed.
