Final answer:
The situation in question represents an example of social bias, where the teacher's actions could unintentionally favor males and reinforce stereotypes, hindering diversity in computer science.
Step-by-step explanation:
The scenario described in the question is an example of social bias. Social bias occurs when individuals or institutions favor one group over another, which can lead to unequal treatment based on characteristics such as gender, race, ethnicity, or sexual orientation. In the context of the question, the computer science teacher's actions of only showcasing and inviting males could perpetuate stereotypes and discourage diversity in the field of technology. By only targeting males and using examples that may not represent all students, the teacher may unintentionally reinforce the notion that computer science is a male-dominated field, reducing the likelihood that females or other underrepresented groups will be interested or feel welcome to participate.
