The Effect of Instruction Based on Web-Quest on Achievement Motivation and Learning of Students in Multigrade Classes in Science Course

This study aimed to investigate the effect of instruction based on Web-Quest on achievement motivation and learning of multigrade students in experimental sciences course through quasi-experimental method. Statistical population for this study included all students from multigrade classes of semi-smart schools of Markazi Province in the 2018-2019 academic year. The participants (n=26) were randomly divided into two groups: an experimental group (n=13) and a control group (n=13). Data were collected using Hermans’ Achievement Motivation Questionnaire and a researcher-made achievement test.
