    We had a very positive experience with Alissa as a tutor for our pod of 5th grade boys from January - June 2020. She cared a lot about the boys and worked hard to create meaningful activities for them. The pod experience was invaluable … More for all of our families during a difficult year and we were so grateful to have found this partnership! We also want to appreciate Craig for helping to match us with a tutor on very short notice after we had cycled through a few folks who were not able to see the commitment through. Thanks for sticking with us!

    Dusty was the exact person we needed to help our child finish out the school year. So grateful to him for the way he steadily encouraged her and helped her stay on track and organized. He is flexible, responsive to our needs/schedule as … More a family, and a delight to be with. We are also thankful that Craig at Themba Tutors really "gets it" and partnered us with such a wonderful tutor who was a great fit for our girl.
  • Avatar Nicole May ★★★★★ 11 months ago
    My child worked with Gillian D virtually for math enrichment. She is an excellent teacher. She took time to understand my child's specific learning style and provided tools that would be engaging. She was kind and empathetic- really … More made it her goal to connect with my child and build trust and rapport. My child started the school year with confidence and without the typically "brain-drain" that occurs over the summer, thanks to Gillian.

Craig and the rest of the Themba team do such an excellent job picking and choosing Themba tutors that suit each client's … More individual needs! I look forward to meeting new tutors and clients in the 2021-2022 school year!
  • Avatar carolina luttmann ★★★★★ 11 months ago
    Our son started in a new high school, 100% remote, and was really struggling with Latin and Physics. I found Themba Tudors online and had an initial call with Craig, who was very knowledgeable, responsive, and found 2 amazing tutors for … More us. Both the Latin and the physics tutors were fantastic, connected with my son really well and helped him go from 'failing' grade to 'honors'! I will for sure continue using (and recommending!) Themba Tutors. Thank you, C, K, and W!

  • Avatar Christine Gennetti ★★★★★ a year ago
    As an adult student diagnosed with a learning disability during grad school, I knew I needed help dealing with my Master's program's demanding workload. I was seriously considering dropping out when I was referred to Themba Tutors. … More I was paired up with a wonderful tutor, Julie, who was a total lifesaver. I learned many techniques that I can utilize in the future as I embark on the next phase of my career.
    I can wholeheartedly say after working with Themba for two years that I would not have finished my program without this organization. And I am so thankful I selected them.
  • Avatar Fabiola FITZPATRICK ★★★★★ 2 years ago
    We were introduced to a wonderful tutor: Mcedwyn. He and our son, a freshman in college, worked well together. As a result, our son’s grades significantly improved. The tutor taught our son subject content and various methods to effectively … More study for quizzes and exams. Our son was also taught time management and organization. My son’s experience with the tutor made the first year of college a less intimidating experience.
  • Avatar Jude Eugene ★★★★★ a year ago
    We have been with our tutor, Cailin Schiller, for two years, from 5th - 7th grade. She started as an executive functioning tutor with my daughter. From the start, she demonstrated a depth of expertise and a selective use of techniques skillfully … More adapted to my daughter’s ADHD and Math disability. Cailin made Math accessible and understandable to her in a way that even her teachers had not been able to do. She differentiated reading, writing and math tasks and assignments to tailor them to my daughter’s unique learning differences. Not only did it have an effect on her grades and her work efficiency, but she finally could do her work with less anxiety. Even my daughter’s teachers used Cailin’s guidance to modify their work with her. But most importantly, she became my daughter’s favorite resource. I can’t say how invaluable Cailin has been to my daughter’s progress and well-being. I’d recommend her a million times over. She is a gem.

    We were very lucky to have found Edwouine Swift, my son's therapist through Themba Tutors. Thomas is 12 years old, and it is extremely difficult to get him to write. Edwouine just works her magic with him, he adores her and is so … More eager to follow her guidance. I have no doubt she will be a positive driving force in his academic future.

What Is Computer Science?

Is your tween or teen interested in technology, computers, or STEM? Does he or she want to be computer literate? Computer literate means knowing computer science, the foundation for computing.


Themba Tutоrѕ can support students with technology at all levels. We offer in-home and online computer science tutoring for 6th through 12th-grade students. Themba Tutors can introduce new skills and concepts or supplement the computer science curriculum at your child’s school. 



computer science3

There is sometimes confusion between “computer science” and the everyday use of computers. Everyday computing is solely focused on the use of technology. Here are the four ways technologies are used at home, in school, and at work.



Computer Literacy


Is the use of digital tools and computer applications, such as creating a PowerPoint or searching the Internet. 



Educational Technology


This is when teachers use computer literacy to support classroom subjects such as Social Studies, Science, Math, or English Language Arts. Activities might include using a web-based application to store writing assignments or creating a podcast for a history research project. 



Digital Citizenship


Is learning how to be responsible with technology and keep information secure.



Information Technology (IT)


Focuses on installing and operating computers and software in industries, businesses, and organizations. There is an overlap with computer science. IT professionals might have a background in computer science.


In contrast, computer science is an understanding of why computers work and how to create those technologies. Computer science actually builds on the four technologies described above. We define computer science asthe study of computers and algorithmic processes, including their principles, their hardware and software designs, their [implementation], and their impact on society (Tucker et. al. 2003, p. 6).

Why Study Computer Science?

At Themba Tutors, our digital literacy tutors will design a learning plan around your student’s needs and are age-appropriate. Our goal is to support your student in being digitally literate and supplementing what your child or teen is learning in school.


Students will learn skills from the list below. The possibilities are endless. 


The world is influenced by technology. Computers and technologies are tools for learning and expression in a variety of disciplines. “To be well-educated citizens in a computing-intensive world and to be prepared for careers in the 21st century, our students must have a clear understanding of the principles and practices of computer science.” (CSTA, 2017,


In 2016, professionals and educators in computer science developed a vision and guidelines for our nation’s schools. The document titled  “The K–12 Computer Science Framework”  ( states Computer science’s ways of thinking, problem-solving, and creating have become invaluable to all parts of life…The K–12 Computer Science Framework envisions a future in which students have informed citizens who can:


  • critically engage in public discussion on computer science topics;
  • develop as learners, users, and creators of computer science knowledge and artifacts;
  • better understand the role of computing in the world around them; and
  • learn, perform, and express themselves in other subjects and interests. 
computer science

Themba Tutors has adopted the vision from the Framework. All students can gain computer science knowledge and become both users and creators of computing technology. Computer Science prepares middle and high school students for a variety of college experiences and careers. As stated by computer educators, “students who graduate with a K–12 computer science foundation will go on to be computationally literate members of society who are not just consumers of technology but creators of it. They will become doctors, artists, entrepreneurs, scientists, journalists, and software developers who will drive even greater levels of innovation in these and a variety of other fields, benefiting their communities and the world.”(

What Do Middle and High School Students Learn in Computer Science?


The great news is that students can learn computer science principles, practices, and skills at any point in their education. Computer science courses are divided into three sections, including core practices, computational thinking skills, and concepts. They are taught in a progression from grades k to 12.  


Themba Tutors align tutoring goals with your school’s curriculum, child’s needs, and skill level. We use the progression chart here published by the CSTA and/or your school’s curriculum to determine a tutoring plan. Progression Chart for Computer Science


First, the core practices are “ways of thinking.” 


Students need the following skills to understand why computers work and how to create these technologies.


The seven practices include:


    1. Fostering an Inclusive Computing Culture
    2. Collaborating Around Computing
    3. Recognizing and Defining Computational Problems
    4. Developing and Using Abstractions
    5. Creating Computational Artifacts
    6. Testing and Refining Computational Artifacts
    7. Communicating About Computing


Second, students need to learn computational thinking skills. 


The core practices, numbers 3 to 6, are these skills broken into learning modules. Computational thinking is the key to computer science. Here is the best definition.  “Computational thinking refers to the thought processes involved in expressing solutions as computational steps or algorithms that a computer can carry out.” (Lee I., 2016)  Students learn how to understand computers’ capabilities, formulate problems to be addressed by a computer, and design algorithms that a computer can execute. (2016, 


Finally, students gain the core concepts of computer science in middle school (level 2) and high school (level 3A). Here are the seven concepts with a few examples of learning in computer science studies.



Computing Systems


This refers to the physical hardware and software (instructions) that communicate and process information in digital form. Students will:

  • learn systems and how the interaction between humans and devices influences design decisions;
  • gain a deeper understanding of the interaction between hardware and software; and
  • explore problem-solving and troubleshooting strategies.



Networks and the Internet


Devices communicate with each other and share information along with cybersecurity.  Students will: 

  • understand how information travels across different networks, and
  • learn ways to protect information systems and networks.



Data and Analysis


This refers to how to collect, process, and store data effectively. 

Students will: 

  • learn what happens when data is collected with computational and automated tools;
  • evaluate different storage methods; 
  • discover patterns and trends and communicate them to others; and
  • practice data science to make inferences, theories, or predictions after collecting data from users or simulations. 


Algorithms and Programming


Algorithms and programming control of all computing systems. An algorithm is a sequence of steps to accomplish a specific task, is translated into programs or code, and provides instructions for computing devices. Students at this level in middle and high school explore the complex world of algorithms after studying programming in elementary school. 


Students will:

  • learn how to develop meaningful and efficient programs
  • organize data collections into data structures that are very complex
  • expand their understanding to more complex execution
  • understand modularity or breaking down tasks into simpler tasks and combining simple tasks to create complex tasks
  • learn the design process and make complex decisions involving user constraints, efficiency, ethics, and testing



Impacts of Computing


Students learn how to be responsible and understand the digital world’s social implications, including equity and computing access. Computing affects people locally, nationally, and globally.


Students will:

  • learn how computing influences culture and, in turn, how culture shapes how people engage with computing (belief systems, language, technology, institutions);
  • understand the social part of computers, including how to connect people, communicate information, and express ideas;
  • discover how institutions and careers are affected by technologies; and 
  • learn the safety, law, and ethics of using computers.
