Texas Courses Update

Professional development courses for CPE credit are transitioning to a new course platform—TEALearn; professional development courses are no longer available through the Texas Gateway. As part of this process, TEA has reviewed courses that were previously offered through the Gateway. This resource provides an update on current status and availability of Classic Gateway courses.

###
Covalent Bonding: Electron Dot Diagrams

Given descriptions, diagrams, scenarios, or chemical symbols, students will model covalent bonds using electron dot formula (Lewis structures).

###
Transformations of Absolute Value Functions

Given an absolute value function, the student will analyze the effect on the graph when f(x) is replaced by af(x), f(bx), f(x – c), and f(x) + d for specific positive and negative real values.

###
Forms of Energy

Given diagrams, illustrations, or descriptions, students will identify the types of energy.

###
Law of Conservation of Energy: Heat Transfer

Given illustrations, scenarios, descriptions, and/or diagrams, students will demonstrate understanding of heat transfer.

###
Thermochemical Equations

Given descriptions, diagrams, scenarios, or chemical symbols, students will calculate the energy changes and identify exothermic and endothermic reactions.

###
Calorimetry

Given scenarios, illustrations, or descriptions, students will identify the process of calorimetry and calculate the heat of a chemical process.

###
Water

Given scenarios, descriptions, or illustrations, the student will determine the properties of water that affect chemical and biological systems.

###
Types of Motion

Students will distinguish between and/or interpret the types of motion.

###
Gravity

Using interactives, students will demonstrate that gravity is the force that governs the motion of our solar system.

###
Using Theoretical and Experimental Probability to Make Predictions

Given an event to simulate, the student will use theoretical probabilities and experimental results to make predictions and decisions.

###
Types of Science Investigations

Students will distinguish between descriptive, comparative, and experimental investigations.

###
Experimental Design

Given investigation scenarios and lab procedures, students will identify independent variables, dependent variables, constants, and control groups.

###
Using Multiplication by a Constant Factor

Given problems involving proportional relationships, the student will use multiplication by a constant factor to solve the problems.

###
Predicting, Finding, and Justifying Data from a Table

Given data in table form, the student will use the data table to interpret solutions to problems.

###
Interpreting Scatterplots

Given scatterplots that represent problem situations, the student will determine if the data has strong vs weak correlation as well as positive, negative, or no correlation.

###
Making Predictions and Critical Judgments (Table/Verbal)

Given verbal descriptions and tables that represent problem situations, the student will make predictions for real-world problems.

###
Collecting Data and Making Predictions

Given an experimental situation, the student will write linear functions that provide a reasonable fit to data to estimate the solutions and make predictions.

###
Writing Expressions to Model Patterns (Table/Pictorial → Symbolic)

Given a pictorial or tabular representation of a pattern and the value of several of their terms, the student will write a formula for the nth term of a sequences.

###
Analyzing the Effects of the Changes in m and b on the Graph of y = mx + b

Given algebraic, graphical, or verbal representations of linear functions, the student will determine the effects on the graph of the parent function *f(x) = x*.
