Gearing up for the AECT conference this week. I will have 3 presentations, a roundtable, and a panel discussion – talk about busy! I will be posting conference updates here in the comments section of this post. My presentations will also be posted to this blog (see placeholders on blog).
Hope to see you in Jacksonville!
Presentation is attached. Presentation is from 215-245 today. Hope to see you there!
Presentation is attached. Presentation will take place from 1-2pm this afternoon. Hope to see you there!
Mobile learning presentation attached. This is a very informative presentation, please attend!
I am exploring this game for my classes so I figured I would post as I learn how to use it. So far there are many possibilities for this game in education. This tutorial goes through creating your first shelter, mining, and crafting tools needed to survive that first night. I did not create this tutorial.

Here is some useful information on the topic that I recently gathered to do a presentation on a mobile learning study I am working on at AECT:
Apps
Here is a link to the apple site which walks you through the process. First you need to pay $99:( Then you download the SDK (standard development kit). At that point you can develop apps, test them, and send them to apple for approval. Remember apple apps are developed using Objective-C. This is actually not that easy of a language for the average programmer to develop with so it may take some time. I have spoken with several advanced programmers who had many difficulties at first when developing with this code so be patient as there may be a steep learning curve.
After toying around with many scripts, I have finally gotten a login script to work. (Note this code was taken from several different websites and modified to work for myself and my students). So here are the directions to create a login/password page to protect your webpages.
1. You need to create a table in a database that includes the columns: username and password. This is the first step and I am assuming you have done this.
2. Create a form in html. Here is my form code. I call this page “login.html”
<html>
<body>
<form action=”login.php” method=”post”>
<p>username
<input type=”text” name=”username” id=”username”>
</p>
<p>password
<input type=”password” name=”password” id=”password”>
</p>
<p>
<input type=”submit”>
</p>
</form>
</body>
</html>
3. Next I create a login script that tests if the login is correct or not. If correct, it logs the user in. I call this page “login.php”. Please note that the 4 words in ALL caps need to be changed to match your information.
<?php
mysql_connect(“SERVERPATHUSUALLYLOCALHOST”, “YOURUSERNAME”,
“YOURPASSWORD”);
mysql_select_db(“YOURDATABASENAME”);
$myusername=$_POST[‘username’];
$mypassword=$_POST[‘password’];
// To protect MySQL injection (more detail about MySQL injection)
$myusername = stripslashes($myusername);
$mypassword = stripslashes($mypassword);
$myusername = mysql_real_escape_string($myusername);
$mypassword = mysql_real_escape_string($mypassword);
$mysql = “SELECT * FROM members WHERE username=’$myusername’ and password=’$mypassword’ “;
$result = mysql_query($mysql) or die(“cannot execute query”);
$count = mysql_num_rows($result);
if($count==1)
{
session_register(‘username’);
header(“location:home.php”); // put your home page neme here
}
else
echo “login fail – please click here to <a href=\”login.html\”>login</a>”;
?>
4. Next I create a welcome page once they have logged in. I call this “home.php”
<?php
session_start();
if(!$_SESSION[‘username’]) {
header(“location:login.php”);
}
?>
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
<html xmlns=”http://www.w3.org/1999/xhtml”>
<head>
<meta http-equiv=”Content-Type” content=”text/html; charset=UTF-8″ />
<title>Untitled Document</title>
</head>
<body>
<p>congrats you have logged in</p>
<p><a href=”test.php”>Check out test page both logged in and out</a></p>
<p><a href=”logout.php”>logout </a></p>
</body>
</html>
5. I then create a test page so you can play around with this once uploaded online. I call this “test.php”
<?php
session_start();
if(!$_SESSION[‘username’]) {
header(“location:login.php”);
}
?>
<?php
echo “you logged in as “.$username;
?>
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
<html xmlns=”http://www.w3.org/1999/xhtml”>
<head>
<meta http-equiv=”Content-Type” content=”text/html; charset=UTF-8″ />
<title>Untitled Document</title>
</head>
<body>
<p> </p>
<p> </p>
<p> </p>
<p>This is a test page so that you can see what happens on pages when users are logged in or out.</p>
<p> </p>
<p><a href=”logout.php”>logout</a></p>
</body>
</html>
6. Finally I create a logout page. This logs the user out. I call this “logout.php”
<?php
session_start();
session_destroy();
echo “successfuly logout”;
?>
<!DOCTYPE html PUBLIC “-//W3C//DTD XHTML 1.0 Transitional//EN” “http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd”>
<html xmlns=”http://www.w3.org/1999/xhtml”>
<head>
<meta http-equiv=”Content-Type” content=”text/html; charset=UTF-8″ />
<title>Untitled Document</title>
</head>
<body>
<p>you have logged out</p>
<p> </p>
<p> <a href=”loginform.html”>log back in </a></p>
<p>visit <a href=”test.php”>test </a>page – you should not have access now and should be redirected to login screen.</p>
</body>
</html>
7. Now for every page on your site that you want to be pass protected, put this script at the very top. This script will check if the user is logged in. If logged in they can access the page. Otherwise they will be directed to the login/register page:
<?php
session_start();
if(!$_SESSION[‘username’]) {
header(“location:login.php”);
}
?>
8. You will probably need to create a form that lets people register but that is for another tutorial.
Has your phone been getting slower? Does it take a few more seconds than normal get to a screen ie sticks? Well there are a few things you can do make your phone much faster. I recently took my Droid 1 and made it nearly new again. Here are a few simple steps to make your phone fast:
1. Get rid of all apps you do not use
2. Get rid of task killer apps. Android 2.1 and later does NOT need these. They take up and waste memory.
3. Use widgets sparingly. They take up a lot of memory. I actually got rid of all of mine except the google search bar and power setting widget. My weather widget was taking a lot of memory.
4. Power off phone once a week.
5. Take the battery out of the phone once a week.
6. Check to see what apps are running and stop them if you are not using them. To do this go to menu->settings->applications->running services
7. Delete all your texts. Using too much space can bog the phone.
8. Clear your internet cache.
9. If you are really desperate you can do a system reboot. This will wipe the phone clean and you need to reinstall everything. I would only do this if you have the time to reinstall or you are having major phone problems.
