The human need to doodle goes back centuries – and Dutch medieval book researcher Erik Kwakkel has proof.

Kwakkel, who teaches at University of Leiden, has spent years examining some of the planet's oldest manuscripts and was amazed to discover the types of things – smiley faces, geometric shapes, random squiggles – medieval scribes and readers would scribble in the margins or back pages of books.

"It's really quite amazing and brings you closer to someone who died a thousand years ago," he told interviewers with NPR's How To Do Everything. "It's quite phenomenal to see that for the first time."

Although some of the doodles Kwakkel has catalogued were made by bored readers, most were created by medieval scribes, testing the ink flow of their pens and quills, prior to copying a book.

"You are actually looking at monks who were in a cell somewhere in a monastery in the middle of nowhere, who grabbed their inkpot to draw a smiley face," Kwakkel said. "It [the doodles] become just as important, I find, as the text that surrounds it."

Metacognition

Metacognition is a critically important, yet often overlooked component of learning. Effective learning involves planning and goal-setting, monitoring one's progress, and adapting as needed. All of these activities are metacognitive in nature. By teaching students these skills - all of which can be learned - we can improve student learning. There are three critical steps to teaching metacognition:

  1. Teaching students that their ability to learn is mutable
  2. Teaching planning and goal-setting
  3. Giving students ample opportunities to practice monitoring their learning and adapting as necessary

Self-Regulated Learning

Expert learners consider their learning goals, plan accordingly, and monitor their own learning as they carry out their plans. Novice learners, in contrast, don't have explicit learning goals, fail to plan, and often have only one learning strategy, which they apply without thinking about whether it's appropriate to the situation. Not surprisingly, novice learners are often disappointed in the results of their studying, while expert learners are generally satisfied with their results (and will make adjustments if not).

Expert learners engage in what we call Self-Regulated Learning. A Self-Regulated Learner begins with goal-setting and planning, taking into account his or her time constraints, strengths and weaknesses relevant to the learning task, and motivation for learning. Having set reasonable goals and planned his or her learning strategies, the Self-Regulated Learner then implements his or her plan, monitoring the results as he or she studies. If the chosen strategies are working well, he or she continues; if not, he or she makes adjustments and monitors the results until they are in line with his or her learning goals.

Expert Learners Can Be Made

Although early attempts to teach students metacognitive skills were unsuccessful, more recent studies demonstrate that metacognition can be taught and learned.

Step 1: Teach students that the ability to learn is not a fixed quantity

The key to a student's ability to become a self-regulated (i.e., metacognitive) learner is understanding that one's ability to learn is a skill that develops over time rather than a fixed trait, inherited at birth. Students who believe that the ability to learn can improve over time earn higher grades, even after controlling for prior achievement (Henderson and Dweck, 1990). These students set reasonable learning goals for themselves and have the self-efficacyto choose and use productive learning strategies. These strategies then result in learning gains. Moreover, students can be taught that their ability to learn can improve over time; those who learn this simple lesson show increased motivation to learn and improved grades (Aronson et al., 2002; Blackwell et al., 2007).

Step 2: Teach students how to set goals and plan to meet them

Many students don't set explicit learning goals for themselves, or make plans to meet any goals they might have. Yet students who received as little as half an hour of training (in the form of one-to-one tutoring) on the process of self-regulated learning outperformed students who did not receive the training in several important ways. First and foremost, they learned more. In addition, they planned how they would spend their time in the learning task, spent more of their time in goal-oriented searching, and periodically reminded themselves of their current goal (Azevedo and Cromley, 2004).

Step 3: Give students opportunities to practice self-monitoring and adapting

Accurate self-monitoring is quite difficult. Many first-year college students, in particular, are over-confident. For example, first-year students at Carnegie Mellon University were asked what grades they anticipated earning in their science and math courses. While results varied somewhat by subject area, more than 90% of students in biology, chemistry, physics and calculus courses expected to earn A's or B's. These expectations were clearly not realistic and suggested some problems on the horizon for these students.

Introduction

Introduction

Metacognition

This summary was compiled by Carol Ormand, SERC.

High-performing students engage in metacognitive activities, monitoring and adjusting their learning strategies (Lovett, 2008). Fortunately, these self-regulating behaviors can be taught, resulting in improved classroom performance (Lovett, 2008; Weinstein et al., 2000).

Metacognition can be learned

A person's ability to learn is mutable, not fixed. In fact, understanding this fact alone can have a profound impact on students' learning (Lovett, 2008). Teaching our students to be strategic learners is therefore one of the most valuable skills we can give them. Courses focusing on students' application of effective learning strategies can improve students' performance in those courses, but can also improve long-term performance and retention of students considered to be at risk (Lovett, 2008; Weinstein et al., 2000). Surprisingly, self-regulating and adaptive behaviors can be taught in minimal class time (literally a matter of minutes over the course of a semester) and students quickly learn to apply these behaviors without prompting (Lovett, 2008). Once the behaviors are internalized, students continue to use them but focus their attention on the content they are learning. The page on teaching metacognition summarizes the key factors in teaching metacognition and offers a few strategies for doing so.

Definitions

Learning Strategies "include any thoughts, behaviors, beliefs, or emotions that facilitate the acquisition, understanding, or later transfer of new knowledge and skills" (Weinstein et al, 2000). Learning strategies are most effective when students can make informed choices about which strategies to use in particular learning situations. This requires that learners have both procedural and conditional knowledge about specific strategies. Procedural knowledge involves knowing how to use a particular learning strategy; conditional knowledge is knowing under what circumstances it is appropriate to use that strategy.
Self-Regulation includes monitoring and reflecting on one's learning strategies and their effectiveness and adjusting accordingly. It also includes monitoring one's affective state while learning and managing it if necessary.

The Role of Metacognition in Learning

An awareness of the learning process can improve learning dramatically (e.g. How People Learn, NRC 2000). Yet students are rarely taught how to develop this awareness. We can help our students to improve their learning by incorporating metacognition into our courses: by having them think about their thinking and by helping them to become aware of and monitor their learning strategies.

  • Dexter Perkins and Karl Wirth convened two sessions at the 2009 GSA annual meeting on fostering the development of metacognition and self-regulation. Most of the presentations are available here: 2009 GSA session on metacognition.

Workshop on the Role of Metacognition in Teaching Geoscience

A workshop on the role of metacognition in teaching geoscience was held at Carleton College, in Northfield, MN, in November, 2008. The workshop program page contains PowerPoint files, suggested teaching strategies and links to working group pages. We have videos of many of the presentations. You can also find essays about metacognition submitted by workshop participants. While the focus of this workshop was in geoscience, the information in these pages is applicable to a wide range of disciplines.

DIY CONCRETE:: Clock

DIY CONCRETE:: Clock

DIY CONCRETE:: Clock

Picture of DIY CONCRETE:: Clock
This Instructable will show you how to cast a fiber-reinforced concrete clock in a melamine box, using a foam knockout to recess the clock hands and mechanism.

About Fiber Reinforced Concrete: CHENG D-FRC is a fiber reinforced concrete mix that is ideal for large or small projects where strength and thinness are desired. Fiber reinforced concrete doesn't contain rock aggregate, instead it contains a range of fibers that act as the aggregate and help bind it together. The 1/4" thickness at the face of this clock is less of a concern with D-FRC because it's designed to be cast thin. The aggregate in regular sacked concrete can be up to 5/8" in size, and getting small forms to fill without large voids can be tricky (a 5/8" rock won't fit in a 1/4" gap). Concrete without aggregate (cement by itself) is brittle, but with that said, try this project even if you're not using fiber reinforced concrete, just take out the larger aggregate, don't mix it too dry, and vibrate the form to remove as much air as possible.

It takes some time to shape the foam knockouts and then they can only be used once, but the foam is relatively easy to shape with hand tools, and the total cost of forming materials is pretty cheap.

Because I didn't have so many pictures of this project, I modeled it in sketchup to help explain the process, hope it helps!
