An experimental investigation on the effects of Web-based instruction / training on cognitive and psychomotor learning

An experimental investigation on the effects of Web-based instruction / training on cognitive and psychomotor learning

Date: August 2000
Creator: Alzafiri, Fayiz M.
Description: The purpose of this study was to investigate the effects of web-based instruction (WBI) on cognitive and psychomotor learning. The subjects of the study received two types of instructional methods, WBI (experimental group) and traditional classroom instruction (control group). Each group received 30 minutes of instruction on "Soldering a Circuit Board." The researcher chose this content subject because it involved both cognitive and psychomotor objectives, which suited the purpose of this study. It was hypothesized that there would be no significant difference between the two methods of instruction, and also that there would be no significant interaction effects between methods of instruction and gender. Forty-six subjects from a population of students enrolled in summer classes offered by the Applied Technology, Training and Development (ATTD) program at the University of North Texas voluntarily participated in this study. Random assignment of subjects was applied in this study. A subject matter expert delivered the content for both the experimental and control groups. To measure cognitive variable, a 10 item, multiple-choice test was administered immediately after instruction. To measure the psychomotor variable, a 15-item checklist was utilized by trained judges to evaluate learners’ performances while soldering. The 2 x 2 factorial model with interaction ...

An Experimental Study of Collision Broadening of some Excited Rotational States of the Bending Vibration of Methyl Cyanide

An Experimental Study of Collision Broadening of some Excited Rotational States of the Bending Vibration of Methyl Cyanide

Date: May 1993
Creator: Hajsaleh, Jamal Y. (Jamal Yousef)
Description: A double modulation microwave spectrometer is used to evaluate the linewidth parameters for some excited rotational components in the bending vibration v_8 of 13CH3 13C 15N and 13CH3C15N isotopomers of methyl cyanide. The linewidth parameters for self-broadening of the ΔJ=2←1 rotational components for the ground v_8 , 1v_8, and the 2v_8 vibrations were determined over a pressure range of 1 to 13 mtorr and at a temperature of 300 K. The double modulation technique is used to explore the high eighth derivative of the line shape profile of the spectral line. This technique proved to give good signal-to-noise ratios and enabled the recovery of weak signals. An experimental method is developed to correct for source modulation broadening. The tests of the ratios of the two inner peak's separation of the eighth derivative of the line showed that they were up to 95% similar to those for a Lorentzian line shape function. The line shapes were assumed to be Lorentzian for the theoretical analysis of the derivative profiles and comparisons were made between experiment and theory on this basis. Dipole moments for vibrationally excited states were calculated from linewidth parameters and show systematic decrease with the increase of excitation. Impact parameters ...

An Experimental Study of Intonation Factors of the Cornet and Trumpet

An Experimental Study of Intonation Factors of the Cornet and Trumpet

Date: August 1971
Creator: McMahon, Ann E. (Ann Elizabeth)
Description: Many musicians have theorized that intonation would be improved if all players in a band or orchestral section used instruments of identical dimensions and material. This study consists of a test taken under experimental conditions comparing the Conn 38A cornets used in the North Texas State University Concert Band with a random selection of trumpets, using the same performers for both sets of instruments.

An Experimental Study of Personality Development in the Stenography Class of the Edinburg High School

An Experimental Study of Personality Development in the Stenography Class of the Edinburg High School

Date: 1948
Creator: Moore, Phelma Newton
Description: The purpose of this study is (1) to make a survey of all personality training procedures in an attempt to adapt those methods to the instructional problems of schools having a large Latin-American enrollment, and (2) to correlate personality development with the study of stenography and job finding by giving it specific emphasis in such a course.

An Experimental Study of Student Progress in General Mathematics

An Experimental Study of Student Progress in General Mathematics

Date: 1947
Creator: Christian, Jewel Morris
Description: The purpose of this investigation is to make an experimental study of the compiled data obtained from the results of three standardized tests that were administered to two groups of general mathematics students during one semester; and to determine, if possible, by the scores, whether the prescribed course in mathematics makes for any significant increases, or losses in student progress.

An experimental study of teachers' verbal and nonverbal immediacy, student motivation, and cognitive learning in video instruction

An experimental study of teachers' verbal and nonverbal immediacy, student motivation, and cognitive learning in video instruction

Date: May 2000
Creator: Witt, Paul L.
Description: This study used an experimental design and a direct test of recall to provide data about teacher immediacy and student cognitive learning. Four hypotheses and a research question addressed two research problems: first, how verbal and nonverbal immediacy function together and/or separately to enhance learning; and second, how immediacy affects cognitive learning in relation to student motivation. These questions were examined in the context of video instruction to provide insight into distance learning processes and to ensure maximum control over experimental manipulations. Participants (N = 347) were drawn from university students in an undergraduate communication course. Students were randomly assigned to groups, completed a measure of state motivation, and viewed a 15-minute video lecture containing part of the usual course content delivered by a guest instructor. Participants were unaware that the video instructor was actually performing one of four scripted manipulations reflecting higher and lower combinations of specific verbal and nonverbal cues, representing the four cells of the 2x2 research design. Immediately after the lecture, students completed a recall measure, consisting of portions of the video text with blanks in the place of key words. Participants were to fill in the blanks with exact words they recalled from the videotape. ...
