We test our theoretical propositions in an experimental study and a quasi-experimental study. In Study 1, we conducted a course experiment with students, seven-wave measurement waves over 4 months resulting in 630 observations from 90 teams. We invited 360 undergraduates from a university in southern China majoring in economics or management. We randomly and equally assigned 360 college students into 90 teams, and then divided the teams into experimental and control groups. We gave the experimental group team reflexivity training and assisted them with reflexivity activities in subsequent sessions, while the control group was given team building training to avoid a placebo effect. We measured team ambidexterity at all seven measurement waves and team reflexivity after and before intervention using established scales and items. Conditional latent growth modeling was applied to test the slope difference of team ambidexterity trend between experimental and control groups. To investigate the theoretical hypotheses in Study 2, we further conducted quasi-experimental study, which took one year, three measurement waves, resulting in 222 observations from 74 teams. We invited a total of 656 employees from R&D teams in 26 companies engaged in high-tech industries related to information technology, precision instruments, and biopharmaceuticals in a southern Chinese province in this study. 74 R&D teams were randomly and equally divided into experimental and control groups. We gave the experimental group team reflexivity training in the first month and required them to conduct a formal reflexivity activity at a regular time each week (or two week) thereafter. We measured team ambidexterity at first and second measurement waves, meta-knowledge sharing and perspective taking at second and third measurement waves. To account for the mediating effect of meta-knowledge sharing and perspective taking between team reflexivity training and team ambidexterity development, latent change scores modeling was applied.
