In numerous studies, intelligent tutoring systems (ITSs) have proven effective in helping students learn mathematics. Prior work posits that their effectiveness derives from efficiently providing eventually-correct practice opportunities. Yet, there is little empirical evidence on how learning processes with ITSs compare to other forms of instruction. The current study compares problem-solving with an ITS versus solving the same problems on paper. We analyze the learning process and pre-post gain data from N = 97 middle school students practicing linear graphs in three curricular units. We find that (i) working with the ITS, students had more than twice the number of eventually-correct practice opportunities than when working on paper and (ii) omission errors on paper were associated with lower learning gains. Yet, contrary to our hypothesis, tutor practice did not yield greater learning gains, with tutor and paper comparing differently across curricular units. These findings align with tutoring allowing students to grapple with challenging steps through tutor assistance but not with eventually-correct opportunities driving learning gains. Gaming-the-system, lack of transfer to an unfamiliar test format, potentially ineffective tutor design, and learning affordances of paper can help explain this gap. This study provides first-of-its-kind quantitative evidence that ITSs yield more learning "opportunities" than equivalent paper-and-pencil practice and reveals that the relation between opportunities and learning gains emerges only when the instruction is effective.

For the forty-fifth time, the Association for Educational Communications and Technology (AECT) is sponsoring the publication of these Proceedings. Papers published in this volume were presented online and onsite during the annual AECT Convention. The Proceedings of AECT's Convention are published in two volumes. Volume #1 contains papers dealing primarily with research and development topics. Papers dealing with the practice of instructional technology including instruction and training issues are contained in Volume #2. This year, both volumes are included in one document.

In this study we present results of a discourse analysis of the interactions between two partners, Uma and Sean, through a feminist lens. During roughly five hours of small group work in a teaching experiment, how each partner used language to position each other's thinking as mathematically significant and establish a collaborative environment varied dramatically. Specifically, Uma shouldered the burden of continuously working to maintain collaboration, oftentimes at the expense of having her thinking positioned as mathematically significant. On the other hand, Sean regularly offered little opportunity for Uma to engage openly with his thinking, which ultimately constrained Uma's opportunities to learn.

This study aimed to evaluate the preparation and characterization of paper towels from watermelon rind waste. The paper towel manufacturing process had several stages: the drying process, pulping process, bleaching process, and printing process. There were five treatments, including paper towels use of NaOH 2.5 M with pulp recycling, paper towels use of 1 NaOH with pulp recycling, paper towels use of 1 NaOH, paper towels use of 1 NaOH with additives, and paper towels use of 1 NaOH with different drying time (110 oC for 60 minutes with ten days of the natural drying). Several characterizations have been employed, such as physical and mechanical properties and optical and chemical properties. The treatments of paper towels were tested, and the test results were compared with SNI 7891: 2017. From the FTIR test, it was observed that the functional groups formed from paper towels from watermelon rind waste. From the Microscope test, paper towels from watermelon skin should be added with materials with long fibers. Based on Physical and Mechanical Characterization, paper towels comply with the SNI. Based on optical characterization, it complies with the SNI for treatments 4 and 5. Chemical characterization is higher than standard. It can be concluded that the natural paper towels from watermelon rind waste comply with the standard of SNI ISO 7891:2017 about Basic Paper towels within the parameter of grammage and water absorption capacity, Tensile strength except for the parameter of tensile strength, pH extract, and fluorescence.

This study traces the evolution of Computer Assisted Language Learning (CALL) through published Research Articles (RAs) in four major journals: "ReCALL," "CALL," "Language Learning & Technology (LL&T)," and "CALICO Journal." The paper outlines the rationale and the methodology of this, which begins with downloading all 2,397 full RAs published in English, from the very first issues up to the end of 2019. This preliminary report already gives an overview of the history of the field; in particular, the increasing number of papers attests to the healthy state of research in CALL. Subsequent analysis focuses on a subcorpus of 426 papers chosen by the frequency of citation in each year as a gauge of impact within the community. The final analysis will use computer tools to help identify methodologies, themes, and theories as they rise and fall over the years.

Generally, development in the pulp and paper industry requires extensive cutting of trees, which in effect contributes to deforestation. The dramatic growth in demand for wood supply, combined with the increasingly increasing cost of timber, has created a surge of interest in the use of non-wood plant fibres for paper production in widely developed countries. The use of waste material in pulping and paper-based industries could be beneficial as it helps prevent the need for disposal, which currently increases agricultural costs and causes environmental deterioration due to pollution and fires. The manufacture of sugarcane bagasse paper may help to minimize deforestation in the development of paper utilizing wood, which also contributes to the creation of biodegradable, biocompatible, and eco-friendly paper utilizing non-wood fibre. This would help the industry to develop sustainable technology in the current economy and environmental order. In the meantime, the magnetic material inside the paper acts as a filler can improves the quality and strength of the paper. While the incorporation of paper radiation will also improve the quality of pulp production, by preventing the presence of fungi on paper. This will be widely used on food wrapping or packaging that is clean is the most important aspect that should be taken to prevent food from being damaged. Biodegradable implies that it can be spontaneously broken down by microorganisms such as bacteria, fungi under some circumstances such as temperature, humidity and others. [ABSTRACT FROM AUTHOR]
