Introducing: On-hover glossaries to support literacy
The 2023 Stile Science Education Report showed that an alarming 57% of teachers believe their students' literacy levels limit their ability to understand science. We want to make science more accessible to every student. To make this a reality, we've created a handy new feature: On-hover glossary! While we start rolling this out, read on to find out more about how the on-hover glossary works.
For a first look at on-hover glossary in practice, take a look at our latest breaking news lesson: Scientists use lasers to steer lightning bolts!.
What is an on-hover glossary?
We've had glossary lessons containing lists of unit-specific vocabulary in each of our units for ages. But, more recently, teachers have asked if we could make these more interactive. This set the wheels in motion for on-hover glossaries.
Within a Stile lesson, the on-hover glossary allows students to see in-line definitions of scientific terminology and cognitive verbs. These words appear with a lovely blue line beneath them to show that a definition is available. By holding their cursor over the underlined word, your students will see a definition and associated image. They can also click the speaker icon to hear the word and its definition read aloud.
To support Spanish-speaking students at Stile schools in the USA, there's an additional button to switch the word, definition, and audio into Spanish. This will support these students in making connections between English and Spanish words and to interpret the text while strengthening their English vocabulary.
Why use an on-hover glossary?
On-hover glossary tools have been shown to support reading comprehension and vocabulary acquisition (Lenders, 2008). This is especially true when the words included in the glossary aren't seen or heard frequently in students' daily lives. We've worked with experts in English Language Development to design and implement an on-hover glossary tool that helps your students interpret scientific terminology and improve their understanding.
Which words have definitions available?
The effectiveness of glossaries and their impact on students "depend critically on the specific rules for glossing words" (Cohen, Tracy & Cohen, 2017, p.262). There's an additional cognitive load associated with using a glossary tool as students switch from reading the text to the definition and then apply the definition in context (ibid.). For this reason, we've been careful not to include too many words and to provide definitions only where they support comprehension. This is also why we've chosen not to include the on-hover glossary in our collection of primary school units.
We've mainly glossed three categories of words, though you might also notice us using the on-hover glossary to provide supporting information. For example, the name of a city or landmark may show details and a map of its location.
The three main categories are:
- Terminology from the unit's glossary
The existing glossary list for each unit provides an excellent source of relevant words and phrases for the on-hover glossary. These same terms are found in the glossary for Stile X and students can also revise them using the flashcards in the Stile X app. - General scientific terminology
Where relevant, we've also included definitions for broader scientific terms. For example, if the word "hypothesis" appears in a lesson, a definition is available. Building students' familiarity with these terms is crucial for their scientific literacy. - Cognitive verbs
Each question in Stile incorporates a cognitive verb. These verbs appear in bold text and give students clear information about how to answer the question. The use of cognitive verbs through frameworks such as SOLO taxonomy supports development of metacognition and self-regulation (Hook, 2018.) but students must first understand their meaning. Student-friendly definitions are available when hovering the cursor over a question's cognitive verb. To avoid confusion with other definitions, cognitive verbs do not include an image and explicitly refer to how students can use the verb to answer the question. To reduce cognitive load, we haven't glossed Depth of Knowledge Level 1 terms like "identify", "name" and "recall".
Talking to students about the on-hover glossary
We recommend taking a minute or two to introduce this new feature to your students when you first encounter it. If they're anything like my students, they might've already discovered it themselves!
Using Teach Mode, project your screen at the front of the room and point out the underlined words in the text. Demonstrate how holding your cursor over these words brings up a definition, image, and speaker icon that will read the definition aloud. An effective strategy for using the glossary is to try to interpret the word's meaning in context before checking the definition. You might like to model this approach for students at the front of the room by thinking aloud. For example, "I see there is a glossary word here. I'm going to read this sentence to see if I understand it before I check the definition. I think I know what an asteroid is, it's something to do with objects in space… I'm going to keep reading to see if my understanding makes sense… Now that I've read a bit further, I think I need to check exactly what it means, because I'm not sure I really understand this section of text without it. I'll hold my mouse over the word and now I can see that an asteroid is a large space rock that orbits the Sun, so when I look back at what I was reading, I understand that there are large space rocks that orbit the Sun between Mars and Jupiter."
Your students may already be familiar with cognitive verbs and how to use them to respond to a question appropriately. If not, check out the Stile Skill builder lesson, designed to help you introduce these words and what they mean. When demonstrating the on-hover glossary function with these terms, scroll to a question and show the underlined cognitive verb, with its definition. Explain that these words are intended to help them understand the level of thinking required for the question, and to construct an appropriate answer. Show a variety of questions with different verbs to demonstrate the guidance each one provides.
