## Quick Overview

Josh Jett argues that science education must shift its focus from excessive standardized testing to fostering student curiosity, experimentation, and inquiry, using the discovery of cells and the characteristics of the protist Euglena as examples of engaging, meaningful learning experiences that are often overshadowed by assessment metrics.

**Key Points:**
- Jett contends that the current system overemphasizes assessments (like PSAT, ELA, FSA, EOC, SAT) over genuine scientific inquiry and experimentation.
- He uses the historical discovery of cells by Robert Hooke in 1665 as a prime example of an inquiry-based discovery that predates modern standardized testing.
- Jett highlights the protist Euglena, noting its fascinating characteristics like being mixotrophic (both predatory and photosynthetic), capable of movement, and possessing an eyespot, all within a single-celled package.
- He contrasts the historical discovery of 'animalcules' by Leeuwenhoek in the 1670s with modern teaching, suggesting that focusing on experiments over rote testing leads to deeper learning.
- Jett explicitly states his proposal is to have less testing and more lab-based activities that encourage student discovery and creativity, which he believes is the true purpose of science education.
- He recounts a personal story where a student asked him which assessment (like the SAT) or district assessment counted the most towards their grade, highlighting the assessment-centric focus.
- Jett concludes by advocating for an educational shift that prioritizes curiosity and inquiry, suggesting that the most profound learning comes from exploration rather than standardized metrics.

**Context:** Josh Jett, a teacher of Biological Sciences and Science Dept Chair at Santa Fe High School, presents at TEDxGainesville High School on the theme 'Innovating for Impact' to discuss necessary changes in science education. He frames his argument by contrasting the overwhelming list of current standardized tests and assessments with historical scientific discoveries and engaging biological examples like the protist Euglena, advocating for a pedagogy centered on experimentation and curiosity.

## Detailed Analysis

Josh Jett delivers a talk advocating for a fundamental shift in science education away from excessive standardized assessments towards inquiry-based learning and experimentation. He begins by listing numerous acronyms representing current tests (PSAT, ELA, FSA, EOC, PM, DCA, AIMS, FCLE, ACT, SAT), noting that for students, these dominate the educational landscape, and for adults, they represent the system's focus. Jett contrasts this with historical science, referencing Robert Hooke's 1665 discovery of cells in cork, an event driven by pure observation through a microscope, not standardized testing. He then focuses on the *Euglena*, a protist he calls his favorite 'animalcule' (a term coined by Leeuwenhoek), detailing its complex features: it is mixotrophic (both predatory and photosynthetic), capable of movement via a flagellum, and possesses an 'eyespot' to detect light—all within a single cell. Jett points out that in his experience, students gravitate toward the fascinating, creative aspects of science, like studying *Euglena* or using iNaturalist, over the tedious nature of assessments. He argues that the current system over-tests, causing students to focus only on what counts toward grades, rather than fostering genuine curiosity. His proposal is to reverse the current dynamic, valuing experiments and inquiry more than formal assessments, moving education toward a more discovery-based model that allows students to learn about themselves and the world around them.

### Introduction & Thesis

- Science Education: Past, Present, Future
- Acknowledging the work of organizers
- Stating the core problem: Assessments are overemphasized
- The comparison of old technology (pager) vs. new (iPhones) illustrates technological evolution.

### The Problem with Current Metrics

- List of Assessments
- Lists acronyms like PSAT, ELA, SAT, ACT
- Suggests these assessments overshadow genuine learning goals
- Contrasts the emphasis on testing with the importance of inquiry.

### Historical Context & Inquiry

- Time Machine Microscopy
- References Robert Hooke's 1665 discovery of 'cells' in cork
- Highlights that discovery was observation-based, not test-driven.

### The Fascination of Biology

- Introducing 'Euglena'
- Details *Euglena*'s traits: mixotrophic, capable of movement (flagellum), possesses an 'eyespot'
- Calls it a 'personal favorite of mine' and a great example of complex life in a unicellular package.

### Proposed Shift

- Assessments < Experiments
- Argues for less testing and more lab-based activities, inquiry, and creativity
- Notes that students are naturally drawn to discovery and exploration.
