Abstract: Disclosed herein are methods and systems for user-interface-assisted composition construction. In an embodiment, a plurality of input fields, each having an argument-element type, is presented via a client-side user interface, initially arranged according to a predefined sequence. Textual inputs are received via the input fields, and corresponding argument-building-block elements are responsively presented via the client-side user interface according to a current arrangement on the client-side user interface of the input fields. Each presented argument-building-block element has the same argument-element type and the received textual input of the corresponding user-interface input field.

Abstract: Disclosed herein are methods and systems for mitigating the effects of intermittent network connectivity in educational settings. A student assignment is presented via a client-side user interface of an educational platform. The client-side user interface is initially operated in a read/write mode. Student input is received via the client-side user interface in connection with the student assignment, and is responsively locally stored. A remote-save-triggering event is detected, and a remote-save method is responsively executed. The remote-save method attempts to save the locally stored student input to a remote server. If the remote-save method returns a remote-save-success promise, the client-side user interface is continued to be operated in the read/write mode. If the remote-save method returns a remote-save-failure promise, the client-side user interface is transitioned to being operated in a read-only mode.
