Software Carpentry lección para la terminal de Unix La terminal de Unix ha existido por más tiempo que la mayoría de sus usuarios. Ha sobrevivido tanto tiempo porque es una herramienta poderosa que permite a las personas hacer cosas complejas con sólo unas pocas teclas. Lo más importante es que ayuda a combinar programas existentes de nuevas maneras y automatizar tareas repetitivas, en vez de estar escribiendo las mismas cosas una y otra vez. El uso del terminal o shell es fundamental para usar muchas otras herramientas poderosas y recursos informáticos (incluidos los supercomputadores o “computación de alto rendimiento”). Esta lección te guiará en el camino hacia el uso eficaz de estos recursos.

This investigation is a lab where students find out if mass is created or destroyed in a closed system. Students will balance the chemical equation to re-enforce their findings.

In Episode 10, young people who are looking for that first job can learn about the basics of the labor market in this country. A brief explanation is given of the roles played by education, supply, demand, productivity and government regulation.

The purpose of this task is to introduce students to exponential growth. While the context presents a classic example of exponential growth, it approaches it from a non-standard point of view. Instead of giving a starting value and asking for subsequent values, it gives an end value and asks about what happened in the past. The simple first question can generate a surprisingly lively discussion as students often think that the algae will grow linearly.

This activity is an on-line research activity in which students research different Minnesota lakes and determine their physical characteristics, chemical characteristics, and the overall health of the lake.

This word problems helps students learn to build the biggest three-digit number given any three numbers between 0 and 9 to use as digits.

In this activity, learners use a laser pointer and two small rotating mirrors to create a variety of fascinating patterns, which can be easily and dramatically projected on a wall or screen. In this version of the activity, learners use binder clips to build the base of the device. Educators can use a pre-assembled device for demonstration purposes or engage learners in the building process.

This activity is a guided inquiry or demonstration where students investigate elastic potential energy and gravitational potential energy and interpret their findings as related to Newton's Laws of motion.

Isaac Newton's famous thought experiment about what would happen if you launched a cannon from a mountaintop at a high velocity comes to life with an interactive computer model. You are charged with the task of launching a satellite into space. Control the angle and speed at which the satellite is launched, and see the results to gain a basic understanding of escape velocity.

An ILD to help demonstrate the Law of Diminishing Marginal Returns using an experiment.

Using spaghetti and marshmallows, students experiment with different structures to determine which ones are able to handle the greatest amount of load. Their experiments help them to further understand the effects that compression and tension forces have with respect to the strength of structures. Spaghetti cannot hold much tension or compression; therefore, it breaks very easily. Marshmallows handle compression well, but do not hold up to tension.

A recent report by the AAC&U (2002) advocates greater emphasis on educating students to be "intentional learners" who are purposeful and self-directing, empowered through intellectual and practical skills, informed by knowledge and ways of knowing, and responsible for personal actions and civic values. Self-directing learners also take initiative to diagnose their learning needs, they formulate learning goals, they select and implement learning strategies, and they evaluate their learning outcomes. It is commonly assumed that students will develop these sorts of skills, motivations, and attitudes in the course of mastering content, but this is not necessarily the case.

In an effort to help students develop these skills, Dexter Perkins and I began introducing a learning co-curriculum into our courses. This curriculum includes readings, classroom activities, discussions, and reflective journaling about learning. These activities not only provide a foundation for developing skills for life-long learning, they also provide scaffolding as students undertake greater responsibility for their own learning. Additionally, students now have a shared vocabulary about thinking and learning, they have a clearer understanding of our expectations for their learning (i.e., that student learning goals should go far beyond memorizing content), and they are more intentional about their own learning. Student motivations and attitudes have changed remarkably with the greater focus on thinking and learning. Furthermore, students more fully understand the value of their learning and their own development.

The aim of this practical guide is to introduce learning analytics to educators in higher education. To this end, we define learning analytics, provide some background to how learning analytics work, explore successful learning analytics implementations, and present findings from an exploratory study of perceptions of the users of learning analytics—educators, students, and advisors—of common metrics and visualizations from learning management system analytic tools at an Ontario university to provide a practical guide to learning analytics.

This is an interactive powerpoint lecture on the science of electricity followed by a laboratory investigation where students dissect a disposable camera.

The purpose of this exercise is to learn how to think about gravity, learn about scientific methodology, and transition from the Aristotelian to Newtonian to Einsteinian understanding of gravity.

Students learn about how biomedical engineers create assistive devices for persons with fine motor skill disabilities. They learn about types of forces, balanced and unbalanced forces, and the relationship between form and function, as well as the structure of the hand. They do this by designing, building and testing their own hand "gripper" prototypes that are able to grasp and lift a 200 ml cup of sand.

Concepts underlying the first of the Essential Principles of the Climate Sciences are aligned with topics typically taught in the elementary grades. This article identifies lessons that will help elementary students develop an understanding of how Sun's light warms Earth and how variations in daylight hours are associated with seasonal change. This article appears in the free, online magazine Beyond Weather and the Water Cycle.

This article highlights lessons and activities for elementary students about the people and cultures of the Arctic region.

This article includes lessons that elementary teachers can use to build the foundations of climate literacy while meeting elementary science standards. Lessons are paired with literacy activities as well.
