Chapter 1 Draft and Research Proposal
Development of MagniVault: A Multipurpose Magnetic Tray for Organizing Small Items Among Students and Teachers, S.Y. 2026–2027
Drafting note. This proposal treats MagniVault as a prototype to be developed and evaluated, not as a proven intervention. The school, grade band, sample size, exact material specification, and locally applicable product-safety requirements must be confirmed before recruitment or fabrication.
1.1 Background of the Study
Students and teachers routinely handle small items such as paper clips, pins, binder clips, keys, and other classroom or study supplies. When these items are left loose on desks or mixed with other materials, they may be difficult to locate, may clutter a work surface, or may be misplaced. These are reasonable design problems to investigate locally; the present proposal does not assume a measured prevalence rate.
Research on classroom environments supports attention to physical context, but it does not establish that a particular organizer will improve learning. In a laboratory study of kindergarten children, highly decorated walls were associated with more distraction, more off-task behavior, and smaller learning gains than a minimally decorated condition Fisher, Godwin, & Seltman, 2014 . An observational study of 58 classrooms also reported associations between visual-environment characteristics and children’s on-task behavior, but observational associations do not demonstrate that an organizer causes an improvement Godwin et al., 2022 . Broader classroom-design research considers multiple environmental factors rather than storage alone Barrett et al., 2015 . Accordingly, this study focuses narrowly on product performance—functionality, usability, organization effectiveness, stability, and durability—not academic achievement.
MagniVault is proposed as a reusable tray with a magnetic surface or magnetic component intended to help retain selected compatible small metal items. Its value is a testable design hypothesis: within a defined task and user setting, the tray may make items easier to keep together and retrieve. That hypothesis must be examined rather than stated as a result. Iterative prototyping is appropriate because sequential testing and refinement can identify design errors and improve a prototype against its requirements Camburn et al., 2017 . Usability should be judged for specified users, goals, and context; ISO defines it in terms of effectiveness, efficiency, and satisfaction in context ISO 9241-11:2018 .
Safety is a central design constraint, not an afterthought. The U.S. Consumer Product Safety Commission warns that swallowed magnets can attract across tissue and cause severe internal injury or death CPSC magnet safety information . U.S. federal requirements apply to certain products containing loose or separable magnets and include performance requirements for qualifying small magnets 16 CFR Part 1262 . Applicability depends on the product’s design, marketing, intended use, and jurisdiction; a school prototype should not be presumed exempt or compliant. The design should therefore avoid exposed detachable magnets, use securely enclosed components, and be reviewed by the school/adviser and, where applicable, a qualified safety authority before student use. If safe containment cannot be demonstrated, testing with minors should not proceed.
1.2 Statement of the Problem
Small classroom and study items can be inconvenient to locate and keep organized during routine work. A magnetic tray may offer a practical, reusable way to gather compatible items, but its performance and suitability for students and teachers in an educational setting are not yet established. In particular, a prototype must be evaluated for whether users can place and retrieve items easily, whether items remain organized during ordinary handling, whether the tray stays stable on a work surface, and whether its structure and magnetic component withstand repeated use without creating unacceptable hazards.
This study will develop and evaluate MagniVault through iterative prototyping and structured user testing in a bounded school setting during S.Y. 2026–2027. It will assess product-level outcomes and will not claim to establish effects on learning, grades, or school-wide organization.
1.3 Purpose and Objectives
The purpose is to develop a MagniVault prototype and assess its functionality, usability, organization effectiveness, stability, durability, and perceived safety for selected students and teachers in an educational setting.
The specific objectives are to:
- Identify user needs and design requirements for a multipurpose tray for small classroom/study items.
- Produce and refine a prototype through at least two design iterations, documenting changes and reasons.
- Assess task completion, retrieval accuracy, retrieval time, and observed handling difficulties in representative organization tasks.
- Obtain structured student and teacher feedback on ease of use, usefulness for the specified tasks, comfort, and perceived safety.
- Test stability and durability using a repeatable protocol and record component loosening, deformation, damage, or loss of magnetic function.
- Use the findings to determine whether the prototype meets pre-set project criteria and to recommend further modification; do not infer effectiveness beyond the tested users, items, and setting.
1.4 Research Questions
- What design requirements do participating students and teachers identify for organizing small classroom and study items?
- To what extent can users complete specified placement and retrieval tasks with the prototype, as measured by completion, accuracy, time, and observed errors?
- How do students and teachers rate the prototype’s ease of use, perceived usefulness for the test tasks, comfort, and perceived safety?
- How well does MagniVault maintain items and remain stable during the defined handling and surface tests?
- What physical wear, damage, or change in function occurs after the specified repeated-use durability test?
- What prototype revisions are indicated by the combined observation, feedback, and test results?
1.5 Significance of the Study
Students. Findings may inform whether this prototype is practical for keeping selected small supplies together during study tasks. Participation is voluntary, and no benefit is promised.
Teachers. Teachers may provide task and classroom-use feedback and may use the findings to judge whether an organizer concept merits further development.
School leaders and research advisers. The project provides a bounded, documented process for reviewing a student-developed product’s usability and safety before any broader use.
Future student researchers. The protocol and design log may serve as a starting point for improved prototypes or broader trials. Results will be local and preliminary; they should not be generalized without replication.
1.6 Scope and Delimitations
The study will take place at one school selected after approval (or, if access is unavailable, one nearby school with formal approval) during S.Y. 2026–2027. The recommended participant groups are (a) one selected grade-level cohort of students—preferably learners aged 13 or older, subject to local confirmation—and (b) classroom teachers who regularly use small supplies in instruction. A feasible target is 12–20 students and 4–8 teachers. This is a purposive, convenience-based product-evaluation sample, not a statistically representative sample. If the school’s rules or project scale require fewer participants, report the actual numbers and treat results as exploratory.
Students should be enrolled in the selected grade, able to understand the assent process and carry out the agreed tasks, and have parent/guardian permission if minors. Teachers should be employed at the participating site, use small supplies in classroom work, and provide informed consent. Exclude anyone who does not consent/assent, whose guardian does not consent where required, or for whom the approved safety protocol indicates the test is unsuitable. Do not exclude learners solely because of disability; provide accessible task alternatives where feasible and approved. Record relevant accommodations without collecting unnecessary sensitive information.
The project covers needs assessment, prototype fabrication, iterative refinement, supervised user testing, and a limited bench durability test. It evaluates only the prototype version(s), item types, setting, and test conditions described in the final protocol. It does not evaluate academic achievement, long-term classroom management, cost-effectiveness at scale, environmental life-cycle impacts, or compliance certification. Results cannot establish long-term durability or safety under all conditions.
1.7 Proposed Product-Development and Evaluation Method
Design and iteration
- Needs assessment: Ask participating teachers and a small student advisory group which small items are commonly misplaced, how they are currently stored, and what tray size, portability, cleaning, and access needs matter. Keep prompts neutral and avoid leading questions.
- Requirements and concept: Convert user input into a short requirements list, including containment, rounded/non-sharp edges, stable base, easy cleaning, visible organization, and safe magnetic construction. Draw at least two concepts and select one with adviser review.
- Prototype 1: Build a low-risk model to check dimensions and layout, then conduct researcher/adviser inspection. Do not distribute detachable magnets or permit unsupervised access.
- Prototype 2: Incorporate feedback and create a functional prototype. Record materials, dimensions, magnetic configuration, assembly method, and changes. If feasible, run a second refinement after preliminary user testing.
- Evaluation: Use the same tasks and protocols for each participant, with the final tested version clearly identified. Any change to the device after testing requires a version record and should not be pooled as if it were the same prototype.
Proposed materials and safety controls
Materials are design choices to be confirmed against local availability and risk review, not established evidence: a smooth, cleanable tray body (for example, a commercially available non-brittle plastic or coated metal), a non-slip base, rounded corners, and a fully enclosed magnetic element or safely retained magnetic insert. Avoid exposed high-powered neodymium magnets, loose magnetic pieces, sharp edges, brittle parts that can fragment, and finishes that chip or shed. Prefer a non-magnetic tray body with a fixed, enclosed magnetic insert if it can retain only the intended items. The adviser should inspect the prototype before use and after each test session. Keep the product away from medical devices where relevant, electronics that may be affected, and persons with implanted devices according to applicable device guidance. Establish stop-use criteria for a cracked housing, loose component, sharp edge, unexpected heating, or any participant discomfort. Confirm applicable national/local standards and school policy; U.S. CPSC sources cited here are safety references, not a determination of legal applicability in the study’s jurisdiction.
Participants and sampling
Use purposive recruitment within a convenience-access school. Include students and teachers as separate user groups because their tasks and experience may differ. Invite eligible participants through school-approved channels; participation must not affect grades, discipline, or employment. The proposed numbers are feasible for a student project and appropriate for descriptive prototype feedback, but are not powered for inferential comparisons. If enrollment permits, seek representation across gender and differing levels of familiarity with the relevant supplies without collecting identifying details unnecessarily.
Data-collection tools and protocol
A. Observation and task sheet. For each user, administer a standardized set of three to five tasks: place designated compatible items in the tray; locate and retrieve a named item; return several items to their designated place; move or gently reposition the tray as instructed. Record task completion (yes/no), correct retrievals, retrieval time in seconds, dropped/misplaced items, requests for help, and observable handling issues. Define start/stop timing rules in advance. Do not use live sharp items; use safe, blunt, school-approved sample objects.
B. Structured user feedback. After tasks, administer a brief 5-point rating form (1 = strongly disagree, 5 = strongly agree) covering ease of placing items, ease of finding/retrieving, clarity of layout, stability, comfort, perceived safety, and willingness to use for the tested tasks. Include two open-ended prompts: “What worked well?” and “What should be changed?” Use age-appropriate wording and pilot the form with a non-participant before data collection. Do not treat a satisfaction rating as proof of objective performance.
C. Stability test. On a level desk, place a pre-specified set of safe items in the tray. Record whether the tray slides or tips during a standardized gentle push or brief surface repositioning. Use the same force/application method each time (e.g., a defined displacement by hand rather than an unmeasured claim of force), and record any item loss. If possible, use a simple inclinometer or marked test surface; specify the chosen method before testing.
D. Durability protocol. Perform a controlled repeated-use test before and after user trials. A feasible school-project protocol is 100 cycles of placing and removing the same safe test items, followed by 10 standardized repositioning cycles on a desk; inspect and photograph the tray at baseline, after each 25 cycles, and at completion. Record cracks, deformation, loosened parts, surface damage, change in magnetic retention (using the same set of compatible test items), and any sharp/exposed component. These cycle counts are proposed study parameters, not an industry standard or certification. A researcher/adviser should document the test procedure and stop immediately if a hazard appears.
E. Design log. Maintain dated sketches/photos, materials and assembly notes, user feedback themes, failures, and design revisions. Obtain permission before photographing participants; preferably photograph the product only.
Analysis and decision criteria
Summarize task outcomes using counts and percentages; report median and range for retrieval time if the sample is small or times are skewed. For ratings, report item-level frequency distributions and median (and range); do not imply scale validation. Summarize open comments and observation notes by recurring themes, retaining anonymized examples. Report student and teacher results separately where numbers allow. Compare Prototype 1 and later versions descriptively only when tasks and conditions are sufficiently comparable.
Before testing, the research team should set practical project targets with the adviser—for example, at least 80% successful completion of each core task, no critical safety event, no detachment or sharp damage, and favorable median usability ratings. These are proposed decision thresholds, not validated benchmarks. Report every threshold and any deviation. If safety failure occurs, halt use regardless of average ratings. A conclusion should say whether the tested prototype met the project’s pre-set criteria under the test conditions, not that MagniVault is universally effective or durable.
1.8 Operational Definitions
- MagniVault: The specific student-developed tray prototype, identified by version number, dimensions, materials, magnetic arrangement, and assembly details.
- Multipurpose magnetic tray: A tray intended to hold or attract more than one category of compatible small items. In this study, “multipurpose” means the item categories actually included in the test protocol, not all small objects.
- Functionality: Whether the prototype performs the defined placement, containment, and retrieval tasks, measured by completion, correct retrieval, item loss, and observable failure.
- Usability: The extent to which the specified student and teacher users can complete the defined tasks effectively and efficiently and report satisfaction in the study context, consistent with the ISO usability framework ISO 9241-11:2018 .
- Organization effectiveness: Performance on the study’s item-placement and retrieval tasks, operationalized as correct retrievals, successful placements, item loss, and retrieval time. It does not mean improved academic performance.
- Stability: The tray’s ability to remain upright and in place, and retain the designated items, during the stated desk-handling test.
- Durability: The prototype’s observable condition and function after the defined repeated-use and repositioning cycles; it is not a prediction of service life.
- Structured user feedback: Responses to the study’s standardized rating and open-response questions following supervised tasks.
- Small items: The safe, predefined, compatible test objects used in this study; the final list must be approved by the school/adviser.
- Selected grade-level cohort: The single grade level approved by the host school for recruitment; the exact grade is to be confirmed before ethics review.
1.9 Ethical and Local Decisions Requiring Confirmation
Before implementation, confirm: (1) school access and written administrative approval; (2) the actual school/site and selected grade/age range; (3) research ethics review or school research approval; (4) parent/guardian permission and student assent for minors, plus teacher consent; (5) applicable national/local product-safety rules and whether the proposed magnetic design is permissible; (6) supervision and incident-response procedures; (7) accessible task adaptations; (8) final materials and safe construction method; (9) whether student participants may handle any magnetic component; and (10) approved data storage, retention, and anonymization. No participant recruitment or student handling of the prototype should begin until these decisions are resolved.
