其他摘要：The purposes of the study were 1) to construct the programmed lessons on atomic structure and periodic table. 2) to develop science learning achievement of 10 th grade students using the programmed lessons and 3) to study students’ satisfaction toward the programmed lessons. The research tools used for the study were 1) the programmed lessons on atomic structure and periodic table”. 2) the assessment form for Index of consistency of the programmed lessons 3) the assessment form for quality of the programmed lessons 4) the students’ satisfaction questionnaire toward the programmed lessons, and 5) the science achievement test (the reliability value was 0.763). The collected data were analyzed by mean, standard deviation and the hypothesis was tested by using the t–test for dependent sample. The results revealed that: 1) the programmed lesson consisted of 3 units, unit 1: atomic structure and periodic table, unit 2: properties of elements, and unit 3: elements and compounds, which the programmed lessons assessed by 5 experts were at level of good quality (x = 3.75). 2) The post test scores were statistically higher than those of the pre–test at the 0.05 level of significance. And 3) the students’ satisfaction toward the programmed lessons was at good level.
