  • What topics will I learn about in Logic & Critical Thinking?

    As a one-semester high school course, Logic & Critical Thinking focuses on helping students become familiar with the key facets of sound reasoning. The course involves weekly readings, recorded lectures, and homework exercises; monthly exams, and culminates with a short capstone paper.

    Before discussing the topics covered, many students and parents will appreciate a brief introduction to logic and critical thinking.

    Logic is part reading comprehension and part math, but more practical and more fun, (unless you’re already a math lover).

    Similar to how we solve math equations, we analyze arguments using logic to determine whether the given information leads to a good conclusion. 

    We need critical thinking skills to help us interpret information we read in the news or hear in our daily conversations. Critical thinking helps us find the logic amidst rhetoric, biases, vagueness, and other fallacies that can obscure or hamper reasoning.

    Almost half the course is spent on aspects of critical thinking such as

    • thinking and communicating clearly
    • separating rhetoric from logic
    • spotting various type of fallacious reasoning.

    Alongside, these aspects, students study aspects of logic such as

    • understanding the flow of arguments
    • recognizing argument forms
    • categorical (Aristotelian) logic with Venn diagrams
    • and truth-functional logic with an introduction to truth tables and formal argument proofs (the fun math side).

    Throughout this process, we will read and discuss short Christian readings on logic. We approach logic as an important structure within God’s creation. Logic enables reasoning which helps us understand, and function well within, the world.

    God’s word makes clear that He interacts with us as thinking beings. So thinking well is especially important for Christians.

    Content Disclaimer: Please note, we will spend time in class analyzing controversial topics and real-world debates. We do not shy away from these topics, since it is important for students to learn how to interpret ideas they will hear on the news and in everyday conversations. However, we do our best to address all topics from a student-friendly and biblical perspective. 


  • How much homework is in Logic & Critical Thinking?

    We estimate that the course workload will take 5–7 hours per week.

    During a typical week in this course, students will complete the following coursework:

    • 60–90 minutes of live class instruction
    • 2-3 video lectures (~15–30 minutes per lecture)
    • Reading assignments (~20–25 pages per week)
    • McGraw Hill Connect homework assignments (~3–6 problems per homework assignment)
    • Puzzle
    • Quiz

    Throughout the year, students will also complete the following tasks:

    • BAT (Basic Argument Transcript) assignment every few weeks (Year total: 8)
    • Exam every few weeks (Year total: 5)
    • Capstone Paper
    • Cumulative final exam
  • What books will I use in Logic & Critical Thinking?

    The official booklist for Logic & Critical Thinking is available now. In the official booklist, you will find information about the editions, book descriptions, and ISBN numbers.

    You can order course materials for competitive prices through our Christian Book Distributors bookstore. Use the Textbook Finder to locate the required resources for your courses. Please note that while most books are available through Christian Book Distributors, some titles are not carried and will need to be purchased elsewhere.

  • Am I ready to take Logic & Critical Thinking

    While there are no special prerequisites for this course, having certain skills and abilities will reduce the stress and workload of this course considerably.

    Logic is a mix between mathematics and reading comprehension—it uses the same skills. So, the more comfortable students are with these two subjects, the more ready they are to succeed. If students struggle with both math and reading comprehension, then they will need to be prepared to spend more time and energy working to master and apply the skills being taught. However, Logic & Critical Thinking is especially useful for students who struggle with reading comprehension or with thinking analytically, and it can do wonders for many students’ SAT® prep for this reason.

    Though the course is designed for students in the 10th grade level and up, the textbook is a college-level text. However, it is an especially straightforward and clear textbook, and should be very readable for most students. Additionally, a basic understanding of sentence grammar (e.g., recognition of subjects, predicates, conjunctions) will go a long way in making aspects of this course more accessible from the start, though students can usually pick up some of this along the way.

    This course involves very little writing, but it does involve consistent homework exercises, which are indispensable. Students with already-developed analytic skills will probably spend 5-7 hours a week, all told (including lectures and live sessions); some students may need to spend closer to 10 hours a week to do well.

  • What is a Live Online Class Session in Logic & Critical Thinking?

    In every HSLDA Academy course, students meet weekly with their instructor and classmates in an online classroom for additional teaching, discussion, Q&A, or group activities. The class sessions are interactive and are conducted using a web meeting software with video, audio, chat, and application sharing capabilities.

    Scheduled, real-time sessions in the online classroom are not the only form of instruction available in a HSLDA Online Academy course, but are offered in addition to lectures or other instructional materials that students are able to access online at their convenience.

    When they register, students will need to select a particular class section and live class meeting time. Additional class sections may be added to the schedule at a later point in the course registration period. Registered students will be notified of any changes to the live session schedule.

  • What if I have a schedule conflict with listed Logic & Critical Thinking class times?

    All live class sessions are recorded for later viewing. While it is recommended that students attend each live class session, students can make arrangements to watch the recordings and receive full participation credit.

    Students should contact their instructor at the start of their course to inform the instructor of any foreseen schedule conflicts.
