Academic Words List

Lorraine Dunn —

The purpose of this document is to give the school community access to a list of the key academic words used across all the subject areas at CBHS.

The words are arranged alphabetically and by year level. Each word is followed by a subject-specific definition and, in some cases, an example (in italics) of how that word might be used in that subject area or a further clarification. Many of these words build on each other over various levels or are used at successive levels, with development in their meaning and expectations.

 

Below is a brief list of key verbs used in the five SOLO Taxonomy levels. Many of these words, or words like them, appear in our school list.

Year 10 and General

Change

Change involves any alteration to the natural or cultural environment. Change can be spatial and/or temporal. Change is a normal process in both natural and cultural environments. It occurs at varying rates, at different times, and in different places. Some changes are predictable, recurrent, or cyclic, while others are unpredictable or erratic. Change can bring about further change.

Cultural

The human environment.

Describe

This means to identify and give an account of; to make reference to the qualities, characteristics or recognisable features. A simple explanation can also be included.

Environments

Environments can be natural and/or cultural. They have particular characteristics and features that can be the result of natural and/or cultural processes. The particular characteristics of an environment may be similar to and/or different from another.

Explain

This means to provide reasons for, to account for, to provide a clear answer, to clarify. Logical reasons are provided.

Interaction

Interaction involves elements of an environment affecting each other and being linked together. Interaction incorporates movement, flows, connections, links, and interrelationships. Landscapes are the visible outcome of interactions. Interaction can bring about environmental change.

Natural

The physical environment.

Patterns

Patterns can be spatial, such as the arrangement of features on the earth’s surface, or temporal, such as how characteristics differ over time in recognisable ways.

Perspectives

The way people view and interpret environments. Perspectives and values may be influenced by culture, environment, social systems, technology, economic and political ideology. They may influence how people interact with environments and the decisions and responses that they make.

Processes

A sequence of actions, natural and/or cultural, that shape and change environments, places and societies. Some examples of geographic processes include erosion, migration, desertification, and globalisation.

Sustainability

Sustainability involves adopting ways of thinking and behaving that allow individuals, groups, and societies to meet their needs and aspirations without preventing future generations from meeting theirs. Sustainable interaction with the environment may be achieved by preventing, limiting, minimizing, or correcting environmental damage to water, air, and soil, as well as considering ecosystems and problems related to waste, noise, and visual pollution.

Aroha

love and empathy. It is an attitude and an important cultural value of Māori, derived from a particular Māori view of the natural world and the place of Māori within it. Aroha is an important concept that underpins a Māori environmental management system.

Kaitiakitanga

to “care for” the environment. It is the sustainable use, management and control of natural and

physical resources that are carried out to the mutual benefit of people and resources.

Taonga

is a resource either physical or cultural that can be found in the environment (including features within the environment e.g. lakes, mountains, rivers, also including people, te reo, whakapapa, etc.).

Tino Rangatiratanga

- includes the rights, responsibilities and obligations involving the use, management and control of the land and other resources.

Whanaungatanga

Māori share a common whakapapa with other people/taonga and therefore a strong sense of responsibility and reciprocal obligations toward those people/taonga. This forms an important part of a holistic world-view. All taonga are interrelated, interconnected and Interdependent. The life force (mauri) of taonga must be protected. The sustainable management of taonga is therefore paramount to our survival.

Year 11 – NCEA Level 1


Apply and integrate

When applying a concept a student uses an appropriate idea; when integrating they will incorporate concepts and evidence into the answer to demonstrate comprehensive understanding.

Describe/explain in

detail

This means the response has complexity showing greater understanding that differentiates it from an Achieved level answer. The response incorporates specific information, case study, facts, names or other explicit information which enhances the answer.

This involves the breaking down or deconstruction of data and examination of the separate parts. When analysing students can identify patterns, trends, relationships, and connections; and synthesise these understandings into explanations. Students should have access to a range of data including maps, graphs, diagrams, tables etc. from which to draw inferences.

Critically analyse

This extends an analysis to involve examination of the factors or circumstances that may have influenced them, identifying and examining any irregularities, examining any relationships that appear etc. A critical analysis will question and/or judge the evidence gained in the analysis.

Critically evaluate

This involves identifying and discussing strengths, weaknesses, opportunities and threats associated with the available options or decisions. Criteria could be established on which to make a final or future judgement.

Justify

Give reasons and evidence why one alternative is better than others.

Rima now moves slightly closer to the pivot of the seesaw. Discuss what will happen to the motion of the seesaw. The seesaw will tilt, moving Rima's end upwards. Her moving towards the pivot will reduce the downwards torque on Rima's side, while keeping the torque on the other side constant. The system will no longer be in equilibrium.

Explain

Write a paragraph linking facts together with the effect/observation, a diagram or calculation might

help


 

Tim and Rima are sitting on a seesaw, they are stationary and both of them are in the air. Explain who we know that the seesaw is in equilibrium. Since the seesaw is stationary, we know that there are no unbalanced forces acting. Since the seesaw is not rotating, we know that there are no unbalanced torques acting. Since the two conditions for equilibrium are satisfied, the seesaw must

be in equilibrium.
