Do you perhaps have headphones with you while this occurs? Earlier it happened randomly when I had enabled Siri in background (listening mode), after disabling it only occurs like I showed in example.

Are you actually able to see when the iPhone places the call or does it show up in Recents? If it shows up in Recents, do you have other devices that use the same Apple ID that your phone number could be linked to? If so, make sure the call isn't being placed from that device and showing up in Recents on your iPhone 14.
Are you experiencing other issues such as apps opening on their own as though the display is being touched? If so, this could be related to display itself.

Understanding how instructional techniques and classroom norms influence in-class student interactions has the potential to positively impact student learning. Many previous studies have shown that students benefit from discussing their ideas with one another in class. In this study of introductory biology students, we explored how using an in-class accountability system might affect the nature of clicker-question discussions. Clicker-question discussions in which student groups were asked to report their ideas voluntarily (volunteer call) were compared with discussions in which student groups were randomly selected to report their ideas (random call). We hypothesized that the higher-accountability condition (random call) would impress upon students the importance of their discussions and thus positively influence how they interacted. Our results suggest that a higher proportion of discussions in the random call condition contained exchanges of reasoning, some forms of questioning, and both on- and off-topic comments compared with discussion in the volunteer call condition. Although group random call does not impact student performance on clicker questions, the positive impact of this instructional approach on exchanges of reasoning and other features suggests it may encourage some types of student interactions that support learning.
We investigated the impact of using a modified version of random call, in which groups, rather than individual students, were randomly called. The effects of group random call on student discussion, to our knowledge, have not yet been investigated. We specifically measured whether group random call influenced the characteristics of in-class student discussions of clicker questions by comparing student discussion in two sections of an introductory biology course. In one section, idea sharing following discussion was voluntary, and in the other section, sharing was enforced through randomly calling on groups to report their ideas to the rest of the class.
In both study conditions, groups were formed in the first 2 weeks of the course. Students were asked to choose their own groups of three to four people and asked to sit and work with their groups for the whole semester. In the volunteer call condition, students were not asked to officially record the makeup of their groups, since groups were not called on by the instructor. In the random call condition, groups were given an index card with a number on the front and were asked to record their names on the back so that their group numbers and names could be called out by the instructor. No additional points were awarded to either volunteers or randomly called groups.
Some of the discussions included in the volunteer call data set have been previously analyzed and reported on, including discussions involving nearby learning assistants (Knight et al., 2015). Only discussions without learning assistant involvement were included in the current analysis.
For freshmen, if no university GPA existed, a predicted GPA, which is calculated using a formula that takes into account high school GPA and standardized test scores, was used. There were no significant differences in % female or class rank (Mann-Whitney U-test) or GPA (independent-samples t test) between volunteer and random call sections. There were also no significant differences between volunteer and nonvolunteer students in each year (unpublished data), except for volunteers in the volunteer call section, who had a significantly higher GPA than nonvolunteers (independent-samples t test, p < 0.05).
The complete data set for this study includes 110 discussions: 46 discussions by six groups of students in the volunteer call condition and 64 discussions by six groups of students in the random call condition. Owing to occasional problems with recording equipment, all question discussions were not captured for each group; on average, eight out of 13 possible discussions were captured per group in the volunteer call condition and 10 out of 13 possible per group in the random call condition.
Students were also surveyed online about their opinions regarding clicker use, group work, and classroom dynamics at the beginning and end of the semester, answering 21 questions on a Likert scale of strongly disagree (1) to strongly agree (5), seven of which were directly related to discussion of clicker questions.
The average turns of speech within a discussion, time given for discussion, discussion length, and percent productivity (discussion length/time given) are shown for discussions in each section. SDs are shown in parentheses.
We characterized performance on clicker questions in two ways: overall performance by the whole class and performance by each recorded group. Class performance averages on the 13 clicker questions used in this analysis were similar between the two sections: 71% (18 SD) correct in the volunteer call condition and 68% (18 SD) correct in the random call condition (p = 0.67, independent-samples t test). In the random call section, the instructors generally asked students to consider their answers to clicker questions individually but did not always ask for an individual vote, while in the volunteer call section, the instructors usually asked for an individual vote and a revote. Because of this difference, we cannot compare gains in clicker performance between the two sections. However, for reference, the average percent correct for the whole class in the volunteer section on the initial vote was 50% (14 SD), similar to previously reported values for initial votes with introductory biology students (Knight et al., 2015).
The whole-discussion codes used in this analysis describe the general features of student clicker discussions with regard to their use of reasoning statements, different kinds of questioning, statements that further discussion, and other short comments (see Table 2 for a complete description of characteristics).
Reasoning about Multiple Answers describes discussions in which the reason(s) for more than one answer choice are discussed. A single individual could describe his or her reasons for multiple answers, or multiple individuals could be discussing their reasons for different answers; thus, this code is distinct from the Exchange of Quality Reasoning. As shown in Table 4, Reasoning about Multiple Answers is seen in a little less than half of student discussions.
Students typically use three kinds of questions in their discussion. The most common question is to ask another student what he or she voted (Requesting Information). The next most common is Requesting Feedback, in which a student first describes his or her reason for an answer and then ends with a question, requesting others to corroborate the idea or to check whether the idea is correct. Least common is Requesting Reasoning, in which a student directly asks another student to explain his or her reason for an answer (Table 4).
In addition to measuring frequency of characteristics within discussions, line-by-line coding of each discussion also allowed us to search for possible reproducible patterns of student interactions. In general, we do not see evidence that student discussions routinely follow an exact pattern, even when the frequency of discussion characteristics used is similar. However, there are some sequences that are similar: for example, a discussion may begin with a series of claims followed by a reasoning statement, or a student question could be followed by background and then a reasoning statement. In Figure 1, we illustrate the sequence of exchanges for two different clicker questions. In Figure 1A, both the random and volunteer call sections had similar exchanges; in Figure 1B, the random call section discussions were similar to each other but different from those in the volunteer call condition. In Figure 1A, discussion had a similar sequence and frequency of interactions and similar total number of turns of speech and length of discussion. In Figure 1B, the random call group discussions used both more turns of speech and more time for their discussions than the volunteer call groups. The random call groups also used a high frequency of Comments, which, as described in Table 4, were more common on average across random call discussion. Despite these differences, the sequences of talk shown here do not appear to impact the performance of the students, as shown by the percent correct (by group) for each discussion.
FIGURE 1. Order of student statements for discussions of the same clicker question by four different groups in each condition. Length of discussion and percent correct by group are shown for each discussion. Each color indicates a category of statements, with abbreviations for each code shown in each square. (A) Example in which discussions of a question were of similar length and turns of speech in both conditions. (B) Example in which discussions of a question were different: random call discussions took both more time and had more turns of speech than the volunteer call discussions.
