Brown University Study Finds 1:1 Online Tutoring Effective for Middle School Math Acceleration

Published

on

NEW YORK, June 17, 2024 /PRNewswire/ — Brown University researchers Matthew Kraft and Virginia Lovison partnered with Littera Education to conduct a pilot study to explore the effect of increasing student-tutor ratios on middle school students’ math achievement and growth during an online tutoring program. The study adds to a small but growing literature that documents the effectiveness of online tutoring programs, and is one of the first to show that 1:1 online tutoring can be effective for accelerating student achievement in middle school math.

To conduct the pilot study, the researchers randomly assigned 180 middle school students to a 10-week online math tutoring program offered during the school day in an individual format or a small group format (3:1) and evaluated the effect on student achievement and growth. They estimate that 1:1 online tutoring produced larger gains in student academic growth in math relative to 3:1 student tutoring, equivalent to 8.10 student growth percentiles.

“The research base for high-impact tutoring is almost entirely built on in-person tutoring programs, which tend to be more expensive and difficult to scale. Success in middle school math is critical for student success in high school and beyond.  We’re excited to demonstrate that scalable, online tutoring can deliver results for students in need of math acceleration,” says Justin Serrano, CEO of Littera.

The researchers also collected Likert-scale and open-ended survey responses from tutors about their experiences delivering online tutoring. A novel feature of the experimental design is that many participating tutors taught both individual (1:1) and small-group (3:1) tutoring sessions during the study. This allowed tutors to compare their experiences across these two different tutoring formats and report back on the experience.

“In addition to the evidence that 1:1 online tutoring promoted students’ academic growth in math, the feedback from tutors providing both 1:1 and small group tutoring was striking,” says Matthew Kraft, an education and economics professor at Brown University. “Tutor feedback revealed the importance of designing tutoring platforms and curricular materials with specific student-tutor ratios in mind and the ways in which tutors need to be supported to overcome the challenges of working with multiple students at once.”

By

SHANGHAI, Nov. 14, 2026 /PRNewswire/ — Windward Bio, a portfolio company of Qiming Venture Partners and a clinical-stage biotechnology company, successfully listed on Nasdaq on November 13, 2026. Windward Bio (Nasdaq: WWB) priced its IPO at $17.00 per share. Its shares closed at $28.50 on the first trading day, up 68% from the IPO price, giving the company a market capitalization of approximately $1.69 billion. This is Qiming Venture Partners’ 11th IPO in 2026.

Qiming Venture Partners invested in Windward Bio’s inaugural Series A financing in 2025 and continued to support the company in its Series B financing in 2026. Qiming also participated in this IPO financing round.

Windward Bio was founded in 2024 with a mission to transform the treatment paradigm for patients living with chronic inflammatory diseases through the development of differentiated biologic therapies targeting clinically validated disease pathways. Led by a team with extensive expertise across discovery, development, and commercialization, Windward Bio is advancing a pipeline of ultra-long-acting antibody medicines to improve clinical outcomes, reduce treatment burden and expand treatment options for patients with serious respiratory and dermatologic diseases, including asthma, chronic obstructive pulmonary disease (COPD) and atopic dermatitis.

Windward Bio’s lead program, WIN378, is a potentially novel anti-TSLP monoclonal antibody engineered for improved potency and extended half-life. WIN378 is currently being evaluated in POLARIS-1, a Phase 2/3 study in severe uncontrolled asthma, and SIRIUS, a Phase 2 study in COPD. The company’s pipeline also includes WIN027, a clinical-stage, long-acting bispecific antibody targeting TSLP and IL-13 with potential applications across multiple inflammatory and immunological diseases. Windward Bio holds exclusive global rights (excluding Greater China and certain Asian countries) to WIN378 through a licensing agreement with Kelun-Biotech and Harbour BioMed, and has separately licensed WIN027 from Qyuns Therapeutics.

“Qiming Venture Partners invests in differentiated, globally competitive biotech innovation designed to address significant unmet needs for patients, and Windward Bio exemplifies this approach. We believe novel, long-acting biologics will reshape the treatment of severe chronic respiratory and skin diseases, and that WIN378 and WIN027 have the potential to expand and meaningfully improve the treatment options available to patients. In the hands of Luca and his team, with their expertise and proven track record, Windward is well-positioned to deliver on this potential, and we look forward to supporting the company through its next phase of growth,” said Alexander Sinclair Wilson, Principal at Qiming Venture Partners.

WeFetch AI Corp. Is the New Name of GreenCore Solutions Corp.

Published

By

gtinfetch.ai, WeFetch.ai’s lead product, removes the guess from artificial intelligence (AI) shopping: the right barcode, and signed proof of it.

VANCOUVER, BC and LONDON, Nov. 13, 2026 /PRNewswire/ — WeFetch AI Corp., the artificial intelligence (AI) shopping company formerly named GreenCore Solutions Corp., has completed its change of name. The Registrar of Companies for British Columbia issued the Certificate of Change of Name on November 13, 2026.

One Answer for Every Barcode

An AI agent picks a product in words. The same words can match a dozen barcodes: the right brand in the wrong size, last year’s pack, a look-alike from another maker. When the agent guesses, the shopper gets the wrong product, the brand loses a sale it had already won, and the retailer pays for the return.

The Company’s lead product, gtinfetch.ai, removes the guess. It answers for 84,810,515 barcodes from 376,271 makers across 3,520,471 points of sale. An AI agent sends a barcode and gets a firm answer: verified, not verified or unknown, with the sources behind it.

Who it matters to:

The shopper gets the product they asked for.The brand keeps the sale the AI already gave it.The retailer does not pay for a wrong order.

A Signed Receipt of Every Check

When an AI agent buys on a shopper’s behalf, someone has to be able to show it bought the right product. Today nobody can: the agent’s choice leaves no record. gtinfetch.ai gives the agent a signed receipt of the check, written at rco.wefetch.ai and open to public verification. The retailer, the brand and the auditor can each see what was checked, when, and what the answer was. The mark is “Barcode verified”.

Three Regions, One Record

The full record now answers from France, Singapore and the United States. Every barcode also has its own free public page at gtinfetch.ai. The three regions are where AI shopping starts. Singapore has the highest consumer use of generative AI in Asia, at 64.3% of working-age people. France stands at 49.6% and the United States at 33.0%, against 18.8% worldwide. (Source: Microsoft AI Diffusion Report, Q2 2026.) They are also the home markets of the AI that shoppers ask: ChatGPT and Claude in the United States, Mistral in France, and Singapore among the top countries in the world for Claude use per head. (Source: Anthropic Economic Index.)

What we built

WeFetch.ai, the barcode fetch system for AI agents. It answers for 84 million products in 70 countries, with 3.5 million points of sale on its own record, and includes:

triggerfetch for brands;shopfetch for shoppers;matchfetch for AI agents;gtinfetch, the record itself.

It is AI native, and works with ChatGPT, Claude, Gemini, Grok, Mistral, Perplexity and Muse. Every answer is signed.

“Words were the first generation of AI answers. Barcodes are agentic commerce,” said Matthew Keddy, Chief Executive Officer of WeFetch AI Corp. “Every AI agent that moves from search results to shopping needs barcode precision. wefetch has it, signed, in three regions.”

The market: Gartner forecasts $2.7 trillion in AI spending in 2026. McKinsey projects that AI agents will orchestrate $3 trillion to $5 trillion in global commerce by 2030, up to $1 trillion of it in US retail. Every one of those AI agent purchases needs the right barcode.

About WeFetch AI Corp.

WeFetch AI Corp. develops AI software products for AI shopping, retail, grocery and fast-moving consumer goods (FMCG). Its lead product, gtinfetch.ai, is the AI agentic shopping barcode engine: 84 million barcodes, answered for the agents of seven AI labs. WeFetch is headquartered in Vancouver, Canada, with sales offices in London, UK. Please visit: wefetch.ai
